Description

PYRAZOLE COMPOUNDS AS TORS OF FSHR AND USES THEREOF RELATED ATIONS The present invention claims the benefit of US provisional application 61/838,460, filed on June 24, 2013, and US. provisional application 61/898,608, filed on November 1, 2013.
The contents of the aforementioned ations are hereby incorporated by reference in their ties.
TECHNICAL FIELD OF THE INVENTION The present invention relates to le compounds useful as agonists of follicle stimulating hormone receptor (FSHR). The invention also provides pharmaceutically acceptable compositions comprising compounds of the present invention and methods of using said compositions in the ent of various disorders.
BACKGROUND OF THE INVENTION Gonadotropins 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 or pituitary under the influence of gonadotropin—releasing hormone and estrogens, and from the placenta during pregnancy. FSH is a heterodimeric rotein e that shares structural similarities with luteinizing hormone (LH) and thyroid stimulating e (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 secretion of estrogens, s LH induces ovulation. In the male, FSH is responsible for the integrity of the seminiferous tubules and acts on Sertoli cells to support gametogenesis.
The hormones are relatively large (28—38 kDa) and are composed of a common 06— subunit non—covalently bound to a distinct B—subunit that confers or binding specificity.
The cellular receptor for these es is expressed on testicular Sertoli cells and n 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. This results in an increase in the level of the intracellular second messenger ine 3', 5'—monophosphate (CAMP), which in turn causes increased steroid synthesis and secretion. Hydropathicity plots of the amino acid sequences of these receptors reveal three general domains: a hydrophilic terminal region, ered to be the amino—terminal extracellular domain; seven hydrophobic segments of membrane—spanning length, considered to be the transmembrane domain; and a carboxy—terminal region that contains ial phosphorylation sites (serine, threonine, and tyrosine residues), considered to be the y— terminal ellular or cytoplasmic domain. The glycoprotein hormone receptor family is distinguished from other G protein—coupled ors, such as the renergic, sin, and substance K receptors, by the large size of the hilic amino-terminal domain, which is involved in hormone binding.
Annually in the U.S. there are 2.4 million 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 ovarial hyperstimulation. Whereas ovulation induction is directed at achieving a single follicle to ovulate, controlled ovarial 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 infertility, e.g. some types of failure of spermatogenesis.
FSHR is a highly ic target in the ovarian follicle growth process and is ively 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 ially be developed for oral stration is desirable. Low molecular weight FSH mimetics with agonistic properties are disclosed in the international applications and WC 2010/ 136438 as well as the patent US 6,653,338. There is still a need for low molecular weight hormone cs that selectively activate FSHR.

As used herein, the term “pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals t undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, l—l9, incorporated herein by reference. Pharmaceutically acceptable salts of the compounds of this invention include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, oric acid, ic acid and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid or malonic acid or by using other methods used in the art such as ion exchange.
Other pharmaceutically acceptable salts include adipate, alginate, ate, aspartate, benzenesulfonate, benzoate, bisulfate, , butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2—hydroxy—ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, esulfonate, thalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3—phenylpropionate, phosphate, te, propionate, stearate, succinate, sulfate, tartrate, anate, p—toluenesulfonate, undecanoate, valerate salts, and the like.

Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lkyl ate and aryl ate.
Unless otherwise stated, structures depicted herein are also meant to include all isomeric (e.g., enantiomeric, diastereomeric, and geometric (or conformational)) forms of the structure; for example, the R and S urations for each asymmetric center, Z and E double bond isomers, and Z and E conformational isomers. ore, single stereochemical isomers as well as enantiomeric, diastereomeric, and geometric (or conformational) mixtures of the present nds are within the scope of the invention. Unless otherwise stated, all tautomeric forms of the compounds of the invention are within the scope of the invention.
Additionally, unless otherwise stated, structures depicted herein are also meant to include compounds that differ only in the presence of one or more ically enriched atoms.
For example, compounds having the present ures ing the replacement of hydrogen by deuterium or tritium, or the replacement of a carbon by a 13C— or 14C—enriched carbon are within the scope of this invention. In some embodiments, the group comprises one or more deuterium atoms.
There is rmore intended that a compound of the formula I includes isotope— d forms thereof. An isotope—labeled form of a compound of the formula I is identical to this compound apart from the fact that one or more atoms of the compound have been replaced by an atom or atoms having an atomic mass or mass number which differs from the atomic mass or mass number of the atom which usually occurs naturally. Examples of isotopes which are readily commercially available and which can be incorporated into a nd of the formula Iby well— known methods include isotopes of hydrogen, carbon, nitrogen, oxygen, phos—phorus, fluo—rine and chlorine, for example 2H, 3H, 13C, 14C, 15N, 18O, 17O, 31P, 32F, 358, 18F and 36CI, respectively.
A compound of the formula I, a prodrug, thereof or a pharmaceutically acceptable salt of either which ns one or more of the above—mentioned isotopes and/or other isotopes of other atoms is intended to be part of the present invention. An isotope—labeled compound of the formula I can be used in a number of beneficial ways. For example, an isotope—labeled compound of the formula I into which, for example, a radioisotope, such as 3H or 14C, has been orated, is suitable for medicament and/or substrate tissue distribution assays. These radioisotopes, i.e. tritium (3H) and —l4 (14C), are particularly preferred owing to simple preparation and excellent detectability. Incorporation of heavier isotopes, for example deuterium (2H), into a compound of the formula I has therapeutic advantages owing to the higher metabolic stability of this isotope—labeled compound. Higher lic stability translates directly into an increased in vivo half—life or lower dosages, which under most circumstances would represent a preferred embodiment of the t invention. An e—labeled compound of the a I can usually be prepared by carrying out the procedures disclosed in the synthesis schemes and the related ption, in the e part and in the preparation part in the present text, replacing a otope—labeled reactant by a readily available isotope—labeled reactant. ium (2H) can also be incorporated into a compound of the formula I for the purpose in order to manipulate the oxidative metabolism of the compound by way of the primary c isotope effect. The y kinetic isotope effect is a change of the rate for a chemical reaction that results from exchange of isotopic nuclei, which in turn is caused by the change in ground state energies necessary for covalent bond formation after this isotopic exchange.
Exchange of a heavier isotope usually results in a lowering of the ground state energy for a chemical bond and thus causes a reduction in the rate in rate-limiting bond breakage. If the bond breakage occurs in or in the vicinity of a saddle—point region along the coordinate of a multi— product reaction, the product distribution ratios can be altered substantially. For explanation: if deuterium is bonded to a carbon atom at a non—exchangeable position, rate differences of kM/kD = 2—7 are typical. If this rate ence is successfully applied to a com—pound of the formula I that is susceptible to oxidation, the profile of this compound in vivo can be drastically modified and result in improved pharmacokinetic properties.
When discovering and developing therapeutic agents, the person skilled in the art is able to optimize pharmacokinetic parameters while retaining desirable in vitro properties. It is reasonable to assume that many compounds with poor pharmacokinetic es are susceptible to oxidative metabolism. In vitro liver microsomal assays currently available provide le information on the course of oxidative metabolism of this type, which in turn permits the rational design of deuterated compounds of the formula I with ed stability through ance to such ive metabolism. Significant improvements in the pharmacokinetic profiles of compounds of the formula I are thereby obtained, and can be expressed quantitatively in terms of ses in the in vivo half—life (t/2), concen-tra—tion at m eutic effect (me), area under the dose response curve (AUC), and F; and in terms of reduced clearance, dose and materials costs.
The following is intended to illustrate the above: a compound of the formula I which has multiple potential sites of attack for oxidative metabolism, for example benzylic hydrogen atoms and en atoms bonded to a nitrogen atom, is prepared as a series of analogues in which various combinations of en atoms are replaced by deuterium atoms, so that some, most or all of these hydrogen atoms have been replaced by deuterium atoms. Half-life determinations enable favorable and accurate determination of the extent of the extent to which the improvement in resistance to oxidative lism has improved. In this way, it is ined that the half—life of the parent compound can be extended by up to 100% as the result of deuterium—hydrogen exchange of this type.
Deuterium—hydrogen exchange in a compound of the formula I can also be used to achieve a favorable modification of the metabolite spectrum of the ng compound in order to diminish or eliminate undesired toxic metabolites. For example, if a toxic metabolite arises through oxidative carbon—hydrogen (C—H) bond cleavage, it can reasonably be assumed that the deuterated analogue will greatly diminish or eliminate production of the unwanted metabolite, even if the particular oxidation is not a rate-determining step. Further information on the state of the art with respect to deuterium—hydrogen exchange may be found, for example in k et al., J. Org. Chem. 55, 3992—3997, 1990, Reider et al., J. Org.

Treatment is also continued after symptoms have resolved, for example to prevent or delay their recurrence.
The nds and compositions, according to the method of the present invention, are administered using any amount and any route of administration effective for treating or lessening the severity of a disorder provided above. The exact amount required will vary from t to subject, depending on the species, age, and general condition of the subject, the severity of the infection, the ular agent, its mode of administration, and the like.
Compounds of the invention are preferably formulated in dosage unit form for ease of administration and uniformity of dosage. The expression "dosage unit form" as used herein refers to a physically te unit of agent appropriate for the patient to be d. It will be understood, however, that the total daily usage of the compounds and compositions of the present invention will be decided by the ing physician within the scope of sound medical judgment. The specific effective dose level for any particular patient or organism will depend upon a variety of factors including the disorder being treated and the ty of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body , general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific nd employed, and like factors well known in the medical arts.
Pharmaceutically acceptable compositions of this invention can be administered to humans and other s orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by s, ointments, or drops), bucally, as an oral or nasal spray, or the like, depending on the severity of the infection being d. In certain embodiments, the compounds of the invention are administered orally or parenterally at dosage levels of about 0.01 mg/kg to about 100 mg/kg and preferably from about 1 mg/kg to about 50 mg/kg, of subject body weight per day, one or more times a day, to obtain the desired therapeutic effect.
Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, mulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms optionally contain inert diluents ly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl l, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3—butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, hylene glycols and fatty acid esters of sorbitan, and es thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, fying and ding agents, sweetening, flavoring, and perfuming agents.

In order to prolong the effect of a compound of the present ion, it is often desirable to slow the absorption of the compound from subcutaneous or intramuscular injection.
This is accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the compound then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered compound form is accomplished by dissolving or ding the compound in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the compound in radable polymers such as ctide— polyglycolide. Depending upon the ratio of compound to polymer and the nature of the ular polymer employed, the rate of compound release can be controlled.
