NOVEL MODULATORS OF FSHR AND USES THEREOF CROSS-REFERENCE [001] This application claims the benefit to U.S. provisional application No.63/401,441 filed August 26, 2022 and U.S. provisional application No.63/522,983 filed June 23, 2023 each of which is incorporated herein by reference in its entirety. BACKGROUND [002] Glycoprotein hormones (e.g. gonadotropins and/or TSH) serve important functions in a variety of bodily functions including metabolism, temperature regulation and the reproductive process. Gonadotropins act on specific gonadal cell types to initiate ovarian and testicular differentiation and steroidogenesis. The gonadotropin FSH (follicle stimulating hormone) is released from the anterior pituitary under the influence of gonadotropin-releasing hormone and estrogens, and from the placenta during pregnancy. FSH is a heterodimeric glycoprotein hormone that shares structural similarities with luteinizing hormone (LH) and thyroid stimulating hormone (TSH), both of which are also produced in the pituitary gland, and chorionic gonadotropin (CG), which is produced in the placenta. In the female, FSH plays a pivotal role in the stimulation of follicle development and maturation and in addition, it is the major hormone regulating synthesis of estrogens, whereas LH induces ovulation. In the male, FSH is responsible for the integrity of the seminiferous tubules and acts on Sertoli cells to support gametogenesis. [003] cellular receptor for these hormones is expressed on testicular Sertoli cells and ovarian granulosa cells. The FSH receptor is known to be members of the G protein-coupled class of membrane- bound receptors, which when activated stimulate an increase in the activity of adenylyl cyclase. monophosphate (cAMP), which in turn causes increased steroid synthesis and secretion. Recent research on FSH receptor has shown that intracellular signaling extends beyond the classic Gs- mediated adenylyl cyclase (cAMP) and includes Gi, Gq proteins and changes in intracellular calcium, and serine/threonine kinases (e.g. MAPK, Akt). Hydropathicity plots of the amino acid sequences of these receptors reveal three general domains: a hydrophilic amino-terminal region, considered to be the amino-terminal extracellular domain , that includes a hinge domain that serves as a tethered inverse agonist; seven hydrophobic segments of membrane-spanning length, considered to be the transmembrane domain; and a carboxy-terminal region that contains potential phosphorylation sites (serine, threonine, and tyrosine residues), considered to be the carboxy -terminal intracellular or cytoplasmic domain. The glycoprotein hormone receptor family is distinguished from other G protein-coupled receptors, such as the β-2-adrenergic, rhodopsin, and substance K receptors, by the large size of the hydrophilic amino-terminal domain, which is involved in hormone binding.

[004] Annually in the U.S. there are millions of couples experiencing infertility that are potential candidates for treatment. FSH, either extracted from urine or produced by recombinant DNA technology, is a parenterally-administered protein product used by specialists for ovulation induction and for controlled ovarian hyperstimulation. Whereas ovulation induction is directed at achieving a single follicle to ovulate, controlled ovarian hyperstimulation is directed at harvesting multiple oocytes for use in various in-vitro assisted reproductive technologies, e.g. in- vitro fertilization (IVF). FSH is also used clinically to treat male hypogonadism and male nonobstructive infertility, e.g. some types of failure of spermatogenesis.

[005] FSHR is a highly specific target in the ovarian follicle growth process and is exclusively expressed in the ovary. However, the use of FSH is limited by its high cost, lack of oral dosing, and need of extensive monitoring by specialist physicians. Hence, identification of a non-peptidic small molecule substitute for FSH that could be developed for oral administration is desirable. There is still a need for low molecular weight hormone mimetics that selectively modulate FSHR.

DETAILED DESCRIPTION Definitions [00335] The terminology used herein is for the purpose of describing particular cases only and is not intended to be limiting. In this application, the use of the singular includes the plural unless specifically stated otherwise. [00336] As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content clearly dictates otherwise. It should also be noted that the term “or” is generally employed in its sense including “and/or” unless the content clearly dictates otherwise. Further, headings provided herein are for convenience only and do not interpret the scope or meaning of the claimed disclosure. [00337] The abbreviations used herein have their conventional meaning within the chemical and biological arts, unless otherwise specified. The chemical structures and formulae set forth herein are constructed according to the standard rules of chemical valency known in the chemical arts. [00338] The symbol ” denotes the point of attachment of a chemical moiety to the remainder of a molecule or chemical formula. [00339] As used herein, the terms “about” or “approximately” can mean within an acceptable error range for the particular value as determined by one of ordinary skill in the art, which may depend in part on how the value is measured or determined, i.e., the limitations of the measurement system. For example, “about” can mean within 1 or more than 1 standard deviation, per the practice in the art. Alternatively, “about” can mean a range of up to 20%, up to 10%, up to 5%, or up to 1% of a given value. Alternatively, particularly with respect to biological systems or processes, the term can mean within an order of magnitude, within 5-fold, or within 2-fold, of a value. Where particular values are described in the application and claims, unless otherwise stated the term “about” meaning within an acceptable error range for the particular value should be assumed. [00340] As used herein, the words “comprising” (and any form of comprising, such as “comprise” and “comprises”), “having” (and any form of having, such as “have” and “has”), “including” (and any form of including, such as “includes” and “include”) or “containing” (and any form of containing, such as “contains” and “contain”) are inclusive or open-ended and do not exclude additional, unrecited elements or method steps. It is contemplated that any embodiment discussed in this specification can be implemented with respect to any method or composition of the present disclosure, and vice versa. Furthermore, compositions of the present disclosure can be used to achieve methods of the present disclosure. [00341] As used herein, the term “derivative” indicates a chemical or biological substance that is related structurally to a second substance and derivable from the second substance through a modification of the second substance. In particular, if a first compound is a derivative of a second compound and the second compound is associated with a chemical and/or biological activity, the first compound differs from the second compound for at least one structural feature, while retaining (at least to a certain extent) the chemical and/or biological activity of the second compound and at least one structural feature (e.g. a sequence, a fragment, a functional group and others) associated thereto. Non-limiting examples of “derivatives” can include a prodrug, a metabolite, an enantiomer, a diastereomer, esters (e.g. acyloxyalkyl esters, alkoxycarbonyloxyalkyl esters, alkyl esters, aryl esters, phosphate esters, sulfonate esters, sulfate esters and disulfide containing esters), ethers, amides, carbonates, thiocarbonates, N-acyl derivatives, N-acyloxyalkyl derivatives, quaternary derivatives of tertiary amines, N-Mannich bases, Schiff bases, amino acid conjugates, phosphate esters, metal salts, sulfonate esters, and the like. In some cases, a derivative may include trivial substitutions (i.e. additional alkyl/akylene groups) to a parent compound that retains the chemical and/or biological activity of the parent compound. [00342] As used herein, the term “pharmaceutically acceptable salt” generally refers to an acid or base salt that is generally considered in the art to be suitable for use in contact with the tissues of human beings or animals without excessive toxicity, irritation, allergic response, or other problem or complication. Such salts include mineral and organic acid salts of basic residues such as amines, as well as alkali or organic salts of acidic residues such as carboxylic acids. Specific pharmaceutical salts include, but are not limited to, salts of acids such as hydrochloric, phosphoric, hydrobromic, malic, glycolic, fumaric, sulfuric, sulfamic, sulfanilic, formic, toluenesulfonic, methanesulfonic, benzene sulfonic, ethane disulfonic, 2-hydroxyethyl sulfonic, nitric, benzoic, 2-acetoxybenzoic, citric, tartaric, lactic, stearic, salicylic, glutamic, ascorbic, pamoic, succinic, fumaric, maleic, propionic, hydroxymaleic, hydroiodic, phenylacetic, alkanoic such as acetic, HOOC-(CH ₂ )n-COOH where n is 0-4, and the like.

[00345] Ranges provided herein are understood to be shorthand for all of the values within the range. For example, a range of 1 to 50 is understood to include any number, combination of numbers, or sub-range from the group consisting of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50, as well as all intervening decimal values between the aforementioned integers such as, for example, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, and 1.9. With respect to sub-ranges, “nested sub-ranges” that extend from either end point of the range are specifically contemplated. For example, a nested sub-range of an example range of 1 to 50 may comprise 1 to 10, 1 to 20, 1 to 30, and 1 to 40 in one direction, or 50 to 40, 50 to 30, 50 to 20, and 50 to 10 in the other direction.

[00347] As used herein, the term “aromatic” generally refers to a planar ring having a delocalized -electron system containing 4n+2 electrons, where n is an integer. Aromatics can be optionally substituted. The term “aromatic” includes both aryl groups (e.g., phenyl, naphthalenyl) and heteroaryl groups (e.g., pyridinyl, quinolinyl). [00348] As used herein, the term “Halo” or “halogen” generally refers to bromo, chloro, fluoro or iodo.

[00352] As used herein, the term "tautomer" generally refers to a proton shift from one atom of a molecule to another atom of the same molecule. The compounds presented herein may exist as tautomers. Tautomers are compounds that are interconvertible by migration of a hydrogen atom, accompanied by a switch of a single bond and adjacent double bond. In bonding arrangements where tautomerization is possible, a chemical equilibrium of the tautomers may exist. All tautomeric forms of the compounds disclosed herein are contemplated. The exact ratio of the tautomers depends on several factors, including temperature, solvent, and pH. Some examples of tautomeric interconversions include: . [00353] As used herein, the terms “effective amount” or “therapeutically effective amount,” generally refer to a sufficient amount of an agent or a compound being administered which will relieve to some extent one or more of the symptoms of the disease or condition being treated. The result can be reduction and/or alleviation of the signs, symptoms, or causes of a disease, or any other desired alteration of a biological system. For example, an “effective amount” for therapeutic uses is the amount of the composition comprising a compound as disclosed herein required to provide a clinically significant decrease in disease symptoms. An appropriate “effective” amount in any individual case may be determined using techniques, such as a dose escalation study. An “effective amount” is an amount sufficient for a compound to accomplish a stated purpose relative to the absence of the compound (e.g., achieve the effect for which it is administered, treat a disease, reduce enzyme activity, increase enzyme activity, reduce a signaling pathway, or reduce one or more symptoms of a disease or condition). An example of an “effective amount” is an amount sufficient to contribute to the treatment, prevention, or reduction of a symptom or symptoms of a disease, which could also be referred to as a “therapeutically effective amount.” A “reduction” of a symptom or symptoms (and grammatical equivalents of this phrase) means decreasing of the severity or frequency of the symptom(s), or elimination of the symptom(s). A “prophylactically effective amount” of a drug is an amount of a drug that, when administered to a subject, will have the intended prophylactic effect, e.g., preventing or delaying the onset (or reoccurrence) of an injury, disease, pathology or condition, or reducing the likelihood of the onset (or reoccurrence) of an injury, disease, pathology, or condition, or their symptoms. The full prophylactic effect does not necessarily occur by administration of one dose, and may occur only after administration of a series of doses. Thus, a prophylactically effective amount may be administered in one or more administrations. An “activity decreasing amount,” as used herein, refers to an amount of antagonist required to decrease the activity of an enzyme relative to the absence of the antagonist. A “function disrupting amount,” as used herein, refers to the amount of antagonist required to disrupt the function of an enzyme or protein relative to the absence of the antagonist. The exact amounts may depend on the purpose of the treatment, and may be ascertainable by one skilled in the art using known techniques (see, e.g., Lieberman, Pharmaceutical Dosage Forms (vols.1-3, 1992); Lloyd, The Art, Science and Technology of Pharmaceutical Compounding (1999); Pickar, Dosage Calculations (1999); and Remington: The Science and Practice of Pharmacy, 20th Edition, 2003, Gennaro, Ed., Lippincott, Williams & Wilkins).

Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds. A person of ordinary skill in the art should note that any carbon as well as heteroatom with valences that appear to be unsatisfied as described or shown herein is assumed to have a sufficient number of hydrogen atom(s) to satisfy the valences described or shown. In certain instances one or more substituents having a double bond (e.g., "oxo" or "=O") as the point of attachment may be described, shown or listed herein within a substituent group, wherein the structure may only show a single bond as the point of attachment to the core structure of Formula (I).

FSH Modulators [00370] For ovulation induction, the only approved medication to date is clomiphene citrate, a mixture of estrogen agonist and antagonist isomers that are used to increase endogenous FSH and LH release. The objective of clomiphene prescription is to increase endogenous plasma FSH levels and LH levels to a level sufficient to support the development of one or two follicles to the point of ovulation. The mechanism of clomiphene or off-label use of aromatase inhibitors is indirect; it assumes a homogeneous response of the hypothalamic-pituitary-ovarian axis across patient subgroups to achieve comparable responders across patients. FSH modulators (e.g. orally active FSH receptor agonists) described herein can show improved ovulation induction with low doses of FSH agonist, for example by directly acting on the ovary and without requiring hypothalamic-pituitary input for efficacy. In this regard, FSH modulators described herein (e.g.oral FSH receptor agonists) can deliver improved efficacy and precision of control over ovulation induction than can be accomplished through administration of clomiphene (approved) or aromatase inhibitors (off-label). [00371] According to one embodiment, the disclosure relates to a method of allosterically modulating FSHR activity in a biological sample comprising contacting said biological sample with a compound of this disclosure, or a composition comprising said compound. According to another embodiment, the disclosure relates to a method of allosterically modulating FSHR, or a mutant thereof, activity in a biological sample in a positive manner, comprising contacting said biological sample with a compound of this disclosure, or a composition comprising said compound. [00372] The compounds of the disclosure are strong and selective modulators of the FSH receptor. In some instances, their selectivity to the FSH receptor can be 3 to 10-fold over the LH receptor and even 10 to 100-fold over the TSH receptor. In some embodiments, the EC ₅₀ or IC ₅₀ amounts to more than 10 μM on unrelated G protein-coupled receptors (GPCR) or non- GPCR targets. In some instances, the selectivity of the FSH modulators to the FSH receptor can be 100 to 200-fold over the LH receptor. The current disclosure comprises the use of the compounds of the disclosure in the regulation and/or modulation of the FSHR signal cascade, which can be advantageously applied as research tool, for diagnosis and/or in treatment of any disorder arising from FSHR signaling. [00373] For example, the compounds of the disclosure are useful in-vitro as unique tools for understanding the biological role of FSH, including the evaluation of the many factors thought to influence, and be influenced by, the production of FSH and the interaction of FSH with the FSHR (e. g. the mechanism of FSH signal transduction/receptor activation). The present compounds are also useful in the development of other compounds that interact with FSHR since the present compounds provide important structure-activity relationship (SAR) information that facilitate that development. Compounds of the present disclosure that bind to FSHR can be used as reagents for detecting FSHR on living cells, fixed cells, in biological fluids, in tissue homogenates, in purified, natural biological materials, etc. For example, by labeling such compounds, one can identify cells having FSHR on their surfaces. In addition, based on their ability to bind FSHR, compounds of the present disclosure can be used in in-situ staining, FACS (fluorescence-activated cell sorting), western blotting, ELISA (enzyme-linked immunoadsorptive assay), etc., receptor purification, or in purifying cells expressing FSHR on the cell surface or inside permeabilized cells. Compounds of the present disclosure that bind to FSHR can also be used to distinguish the effects of FSH that are independent of carbohydrate moieties that comprise the glycoprotein nature of FSH, and to identify essential and alternative cellular responses of the small molecule FSHR agonist relative to the glycoprotein FSH. [00374] The compounds of the disclosure can also be utilized as commercial research reagents for various medical research and diagnostic uses. Such uses can include but are not limited to: use as a calibration standard for quantifying the activities of candidate FSH agonists in a variety of functional assays; use as blocking reagents in random compound screening, i.e. in looking for new families of FSH receptor ligands, the compounds can be used to block recovery of the presently claimed FSH compounds; use in the co-crystallization with FSHR receptor, i.e. the compounds of the present disclosure will allow formation of crystals of the compound bound to FSHR, enabling the determination of receptor/compound structure by x-ray crystallography or cryoEM; other research and diagnostic applications, wherein FSHR is preferably activated or such activation is conveniently calibrated against a known quantity of an FSH agonist, etc.; use in assays as probes for determining the expression of FSHR on the surface of cells; and developing assays for detecting compounds which bind to the same site as the FSHR binding ligands. [00375] The compounds of the disclosure can be applied either themselves and/or in combination with physical measurements for diagnostics of treatment effectiveness. Pharmaceutical compositions containing said compounds and the use of said compounds to treat FSHR-mediated conditions is a promising, novel approach for a broad spectrum of therapies causing a direct and immediate improvement in the state of health, whether in human or animal. The impact is of special benefit to efficiently combat infertility, either alone or in combination with other fertility- inducing treatments. [00376] In particular, the compounds of the disclosure potentiate the native FSH effect for both ovulation induction and assisted reproductive technology. The orally bioavailable and active new chemical entities of the disclosure improve convenience for patients and compliance for physicians. [00377] The compounds of the disclosure are active in the primary screen (CHO with or without FSH), selective in secondary screen (no or low activity against TSHR and LHR) and potent in the granulosa cell estradiol assay. Neither hERG nor any toxic effects can be observed in-vitro. [00378] In certain embodiments, the disclosure provides a method for in-vitro fertilization comprising: (a) treating a mammal according to the method as described above, (b) collecting ova from said mammal, (c) fertilizing said ova, and (d) implanting said fertilized ova into a host mammal. [00379] Described herein are FSH modulator compounds, pharmaceutically acceptable salts or solvates thereof, pharmaceutical compositions comprising FSH modulator compounds (or pharmaceutically acceptable salts or solvates thereof), lipid nanoparticle compositions comprising FSH modulators, and methods of treating a disease comprising administering FSH modulator compounds, pharmaceutically acceptable salts or solvates thereof, pharmaceutical compositions comprising FSH modulator compounds (or pharmaceutically acceptable salts or solvates thereof), and/or lipid nanoparticle compositions comprising FSH modulators (or pharmaceutically acceptable salts or solvates thereof), as described herein, to a subject in need thereof. [00380] In some embodiments, the compounds of the disclosure can show low activity or no activity on FSHR as agonists. Such low activity agonists can have similar structural features as potent FSHR agonists are antagonists of the glycoprotein hormone FSH. In some embodiments, an inactive (e.g. a low activity) FSHR compound can displace and inhibit the activity of a potent FSHR agonist of a similar structural feature. Such compounds can be useful as a diagnostic too by displacing agonist without having agonist activity itself. [00381] In some instances, inactive compounds of the disclosure can attenuate the activity of a more active compound by displacing the agonist activity of the more active compound. In some embodiments, inactive compounds can be useful, for example, to prevent over-stimulation of agonist response in women and/or to avoid or mitigate ovarian hyperstimulation syndrome. [00382] In some instances, FSH modulators or compositions described herein are compounds of Formula (I): [00383] [00384] or a pharmaceutically acceptable salts thereof.

[00518] In some cases FSH modulators described herein can have a structure of any of the compounds of Table 1. Table 1. Structures of additional example FSH Modulators.

[00519] In some instances, FSH modulators described herein can have any structure described herein, including, but not limited to, those described in FIGs.1-193, in the Examples, and/or the synthetic schemes throughout the instant application, and pharmaceutically acceptable salts, solvates, or formulations thereof.

[00524] In some embodiments, the disease or condition is Klinefelter syndrome. [00525] In some embodiments, the disease or condition is primary ovary insufficiency (POI). [00526] Further described herein described herein are pharmaceutical compositions comprising a compound of any one of claims or a pharmaceutically acceptable salt or pharmaceutically acceptable solvate thereof, and a pharmaceutically acceptable excipient or carrier. [00527] Pharmaceutically acceptable lipid nanoparticle formulation can comprise any of the compounds described herein. [00528] Any of the methods described herein can comprise treating a condition or disease by administering any compound, pharmaceutically acceptable salt, and/or pharmaceutically acceptable solvate described herein to a subject in need thereof. [00529] Any of the methods described herein can comprise use of any compound, pharmaceutically acceptable salt, and/or pharmaceutically acceptable solvate described herein in the manufacture of a medicament for the treatment of a condition or disease. [00530] The compounds of formula (I) , their salts, isomers, tautomers, enantiomeric forms, diastereomers, racemates, derivatives, prodrugs and/or metabolites are characterized by a high specificity and stability, low manufacturing costs and convenient handling. These features form the basis for a reproducible action, wherein the lack of cross-reactivity is included, and for a reliable and safe interaction with the target structure. [00531] Modulation of FSHR, or a mutant thereof, activity in a biological sample is useful for a variety of purposes that are known to one of skill in the art. Examples of such purposes include, but are not limited to, blood transfusion, organ transplantation, biological specimen storage, and biological assays. Further Forms of Compounds [00532] In some embodiments, compounds described herein are prepared as prodrugs. A “prodrug” refers to an agent that is converted into the parent drug in vivo. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. In some embodiments, the design of a prodrug increases the effective water solubility. An example, without limitation, of a prodrug is a compound described herein, which is administered as an ester (the “prodrug”) to facilitate transmittal across a cell membrane where water solubility is detrimental to mobility but which then is metabolically hydrolyzed to the carboxylic acid, the active entity, once inside the cell where water-solubility is beneficial. A further example of a prodrug might be a short peptide (polyaminoacid) bonded to an acid group where the peptide is metabolized to reveal the active moiety. In certain embodiments, upon in vivo administration, a prodrug is chemically converted to the biologically, pharmaceutically or therapeutically active form of the compound. In certain embodiments, a prodrug is enzymatically metabolized by one or more steps or processes to the biologically, pharmaceutically or therapeutically active form of the compound. [00533] In one aspect, prodrugs are designed to alter the metabolic stability or the transport characteristics of a drug, to mask side effects or toxicity, to improve the flavor of a drug or to alter other characteristics or properties of a drug. By virtue of knowledge of pharmacokinetic, pharmacodynamic processes and drug metabolism in vivo, once a pharmaceutically active compound is known, the design of prodrugs of the compound is possible. (see, for example, Nogrady (1985) Medicinal Chemistry A Biochemical Approach, Oxford University Press, New York, pages 388-392; Silverman (1992), The Organic Chemistry of Drug Design and Drug Action, Academic Press, Inc., San Diego, pages 352-401, Rooseboom et al., Pharmacological Reviews, 56:53–102, 2004; Aesop Cho, “Recent Advances in Oral Prodrug Discovery”, Annual Reports in Medicinal Chemistry, Vol.41, 395-407, 2006; T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems, Vol.14 of the A.C.S. Symposium Series). [00534] In some embodiments, some of the herein-described compounds may be a prodrug for another derivative or active compound. [00535] In some embodiments, sites on the aromatic ring portion of compounds described herein are susceptible to various metabolic reactions Therefore incorporation of appropriate substituents on the aromatic ring structures may reduce, minimize or eliminate this metabolic pathway. In specific embodiments, the appropriate substituent to decrease or eliminate the susceptibility of the aromatic ring to metabolic reactions is, by way of example only, a halogen, or an alkyl group. [00536] In another embodiment, the compounds described herein are labeled isotopically (e.g., with a radioisotope) or by another other methods, including, but not limited to, the use of chromophores or fluorescent moieties, bioluminescent labels, or chemiluminescent labels. [00537] Compounds described herein include isotopically-labeled compounds, which are identical to those recited in the various formulae and structures presented herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into the present compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, sulfur, fluorine, chlorine, and iodine such as, for example, ² H, ³ H, ¹³ C, ¹⁴ C, ¹⁵ N, ¹⁸ O, ¹⁷ O, ³⁵ S, ¹⁸ F, ³⁶ Cl, and ¹²⁵ I. In one aspect, isotopically-labeled compounds described herein, for example those into which radioactive isotopes such as ³ H and ¹⁴ C are incorporated, are useful in drug and/or substrate tissue distribution assays. In one aspect, substitution with isotopes such as deuterium affords certain therapeutic advantages resulting from greater metabolic stability, such as, for example, increased in vivo half-life or reduced dosage requirements. [00538] In additional or further embodiments, the compounds described herein are metabolized upon administration to an organism in need to produce a metabolite that is then used to produce a desired effect, including a desired therapeutic effect. [00539] Compounds described herein may be formed as, and/or used as, pharmaceutically acceptable salts. The type of pharmaceutical acceptable salts, include, but are not limited to: (1) acid addition salts, formed by reacting the free base form of the compound with a pharmaceutically acceptable: inorganic acid, such as, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, metaphosphoric acid, and the like; or with an organic acid, such as, for example, acetic acid, propionic acid, hexanoic acid, cyclopentanepropionic acid, glycolic acid, pyruvic acid, lactic acid, malonic acid, succinic acid, malic acid, maleic acid, fumaric acid, trifluoroacetic acid, tartaric acid, citric acid, benzoic acid, 3-(4-hydroxybenzoyl)benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, 1,2-ethanedisulfonic acid, 2-hydroxyethanesulfonic acid, benzenesulfonic acid, toluenesulfonic acid, 2-naphthalenesulfonic acid, 4-methylbicyclo-[2.2.2]oct-2-ene-1- carboxylic acid, glucoheptonic acid, 4,4’-methylenebis-(3-hydroxy-2-ene-1-carboxylic acid), 3- phenylpropionic acid, trimethylacetic acid, tertiary butylacetic acid, lauryl sulfuric acid, gluconic acid, glutamic acid, hydroxynaphthoic acid, salicylic acid, stearic acid, muconic acid, butyric acid, phenylacetic acid, phenylbutyric acid, valproic acid, and the like; (2) salts formed when an acidic proton present in the parent compound is replaced by a metal ion, e.g., an alkali metal ion (e.g., lithium, sodium, potassium), an alkaline earth ion (e.g., magnesium, or calcium), or an aluminum ion. In some cases, compounds described herein may coordinate with an organic base, such as, but not limited to, ethanolamine, diethanolamine, triethanolamine, tromethamine, N- methylglucamine, dicyclohexylamine, tris(hydroxymethyl)methylamine. In other cases, compounds described herein may form salts with amino acids such as, but not limited to, arginine, lysine, and the like. Acceptable inorganic bases used to form salts with compounds that include an acidic proton, include, but are not limited to, aluminum hydroxide, calcium hydroxide, potassium hydroxide, sodium carbonate, sodium hydroxide, and the like. [00540] It should be understood that a reference to a pharmaceutically acceptable salt includes the solvent addition forms, particularly solvates. Solvates contain either stoichiometric or non- stoichiometric amounts of a solvent, and may be formed during the process of crystallization with pharmaceutically acceptable solvents such as water, ethanol, and the like. Hydrates are formed when the solvent is water, or alcoholates are formed when the solvent is alcohol. Solvates of compounds described herein can be conveniently prepared or formed during the processes described herein. In addition, the compounds provided herein can exist in unsolvated as well as solvated forms. In general, the solvated forms are considered equivalent to the unsolvated forms for the purposes of the compounds and methods provided herein.

The protein coding region was confirmed by sequence analysis to be in-frame and of the expected sequence, matching the following accession numbers: FSHR NM 000145, TSHR NM 000369, and LHCGR NM_000233.

[00910] HTRF cAMP assays were performed using Chinese Hamster Ovary (CHO-K1) cell lines transiently expressing human FSH, TSH, and LHCG receptors. 48 hours before the assay, cells were washed with PBS and then dissociated from tissue culture flasks with 0.25% trypsin. Dissociated cells were quenched in full media (F-12K Medium Coming REF#10-025-CV, 10% Avantor Seradigm FB Essence Cat# 10803-034, 1% Penicillin/Streptomycin Cytiva HyClone Cat#SV30010) and then collected by centrifugation at 290 x g for 5 min. Cells were resuspended in full media and dispensed into 150 mm cell culture dishes (Nest Scientific Cat#715001), at 2.3 x 10 ⁶ cells/flask. 7 hours later, cells were transfected using Lipofectamine transfection reagent (Invitrogen Cat#l 8324020). Briefly, 60 μL of lipofectamine was dispensed into 2 mL of Opti- MEM (Gibco Cat# 31985070) and incubated for 5 minutes at room temperature. Then, the mixture was added onto 12 g of DNA and incubated for another 20 minutes at room temperature. Cells were washed with warm (37°C) PBS.17.5mL of Opti-MEM was dispensed onto the cells, followed by addition of the Opti-MEM/lipofectamine/DNA mixture. Cells were incubated overnight in a 37°C, 5% CO ₂ cell incubator.17-19 hours later, Opti-MEM was aspirated off the cells and replaced with full media. Cells were incubated for another 24 hours in a 37°C, 5% CO ₂ cell incubator. [00911] On the day of the assay, cells were washed with PBS and then dissociated from tissue culture flasks with 0.25% trypsin. Dissociated cells were quenched in full media and then collected by centrifugation at 290 x g for 5 min. Cells were resuspended in PBS ^+/+ (Corning REF#20-030-CV) to a concentration of 2x10 ⁵ cells/mL.10 L/well of cells (2,000 cells/well) were dispensed into 384-well Corning plates (REF#3825), in triplicate. Cells were incubated at room temperature for 2 hours. [00912] Example FSHR Modulator compounds were diluted in assay buffer (PBS ^+/+ , 0.05% BSA Sigma-Aldrich A3059, 500 M IBMX Sigma-Aldrich I5879) to 3.5x the final assay concentration.4 L of test agonist was added to the cells and incubated for 1 hour at room temperature.10 L of cAMP detection reagents (LANCE Ultra cAMP Detection Kit PerkinElmer TRF0264) were dispensed onto the cells and plates were incubated for 2 hours at room temperature (cAMP detection reagents were made according to the PerkinElmer kit protocol). Plates were read on an Envision plate reader following PerkinElmer guidelines. [00913] Raw data for all assays was transmitted directly from plate readers into a database for processing. All assay plates contained both positive and negative control wells to allow for data normalization and scaling. In agonist assays, negative control wells contained assay buffer and positive control wells contained 10 M positive control (10nM Follicle Stimulating Hormone Sigma-Aldrich F4021, 50nM Thyroid Stimulating Hormone Sigma-Aldrich 869006, 50nM Luteinizing Hormone MyBioSource MBS5308806, for their respective receptors). All control wells contained DMSO at a final assay concentration that matched the test compound wells. [00914] In addition to buffer and acetylcholine containing negative and positive control wells, all assay plates contained an 8-point, quadruplicate cAMP standard curve. Counts from the standard curve wells were used to generate a sigmoidal standard curve, which was used to transform the raw counts from each well on the plate (scaling control wells and compound wells) into a pmol/well cAMP value. The pmol/well values for compound wells were scaled to the values in the positive and negative control wells to generate % control values. The negative control wells defined 0% response and the positive control wells defined 100% response. Data from test compound wells was scaled to these controls and are reported as % control values. Reported agonist efficacies represent the % efficacy compared to a maximal positive control response. [00915] Percent control data were analyzed by non-linear regression with a sigmoidal dose response algorithm in the database to yield potency and efficacy data. Table 2.
