Osteoporosis is a skeletal disorder characterized by low bone density and disrupted bone tissue architecture, which leads to the increased risk of fracture. Existing pharmacological treatments inhibit osteoclast bone-resorption activity or stimulate differentiation and increase the functional activity of osteoblasts. For example, bisphosphonates (e.g., alendronate) increase structural bone strength by promoting increased bone volume and density (Appelman-Dijkstra et al., Clinical Endocrinology & Metabolism, 28, 843-857 (2014)). However, with the approval of the receptor activator of NF-kappaB ligand (RANKL) inhibitor denosumab, the most potent antiresorptive agent, new approaches in this class of therapeutics have been mainly exhausted. In contrast, the use of parathyroid hormone peptides is the first and only available anabolic approach to stimulate osteoblast differentiation through activation of several cellular transduction pathways, including canonical WNT signaling. However, peptide treatment requires daily injections and is expensive. Other agents such as sclerostin, GSK-30, Dickkopf-1 (Dkk1) inhibitors, activins, bone morphogenetic protein (BMP) stimulators, and nitroglycerin have been tested in clinical trials with mixed success. All these drugs have some drawbacks. For example, bisphosphonate treatments are only beneficial for 3-5 years, while alendronate and reloxifene decrease fractures in the spine but not in other sites.
Insulin-like3 hormone is a peptide in the relaxin/insulin-like family. It is produced continuously after birth, primarily in testicular Leydig cells and follicular ovarian cells (Sozubir et al., J Urol, 183, 2373-2379 (2010); and Nef et al., Nat Genet, 22, 295-299 (1999)). It was discovered that human patients with mutations of the INSL3 G protein-coupled receptor (RXFP2) manifested osteoporosis or osteopenia (Ferlin et al., Journal of Bone andMineral Research, 23, 683-693 (2008)). The abnormalities detected in patients with non-functional alleles suggested the role of INSL3/RXFP2 signaling in bone metabolism. The level of INSL3 declines in men with the loss of normal testicular function during aging (Anand-Ivell et al., Int J Androl, 29, 618-626 (2006)) whereas the risk of osteoporosis increases. The XXY patients with Klinefelter Syndrome (KS), a disease associated with small testes, have a high risk of developing osteoporosis and osteopenia and a consequent increased risk of fractures.
Consistent with the human phenotype, bone histomorphometric, and micro computed tomography (pCT) analyses of Rxfp2−/−knockout mice generated showed decreased bone mass, mineralizing surface, bone formation, and osteoclast surface compared with wild-type littermates. These data suggested that the low bone mass phenotype in the Rxfp2−/− mice is linked to functional osteoblast impairment causing little bone formation, little mineralizing surface, and ultimately, a negative balance between bone formation and bone resorption.
Alternatively, relaxin peptide acting through its receptor RXFP1, expressed on human peripheral blood monocytes, regulate their differentiation into mature osteoclasts, osteoclast survival and activation (Ferlin et al., Bone, 46, 504-513 (2010)). Thus, two members of the same peptide family play opposing roles in bone metabolism: INSL3 stimulates bone growth, relaxin has the opposite effect. Studies in mice with the RXFP2 deletion and INSL3 overexpression show that INSL3 is the only cognate ligand for RXFP2 in vivo (Bogatcheva et al., Molecular Endocrinology, 17, 2639-2646 (2003)). Moreover, an analysis of ligand-receptor interaction suggests that INSL3 and relaxin utilize different binding modes and distinct sites within the receptor (Scott et al., Mol Endocrinol, 26(11), 1896-1906 (2012)).
Besides the use of RXFP2 agonists as therapeutic agents in the induction of bone differentiation, there are numerous other potential research and clinical applications for such activators. A major role for INSL3/RXFP2 signaling has been demonstrated in testicular descent and cryptorchidism, which typically is treated by orchiopexy surgery (Agoulnik et al., Methods in Molecular Biology, 825, 127-147 (2012); Bogatcheva et al., Reproductive Biomedicine online, 10, 49-54 (2005); and Ferguson et al., Frontiers in Endocrinology, 4, 32 (2013)). However, there are notable risks associated with orchiopexy surgery, such as infection, bleeding, anomalous healing, damage to the blood vessels and other structures in the spermatic cord resulting in the loss of testis, failure of the testis to remain in the scrotum, urination problems, pathology, and slow recovery. No reliable pharmacological intervention exists for treating cryptorchidism apart from a GNRH/hCG gonadotropin hormone regiment with an overall 15-20% success rate.
In addition, a role for INSL3/RXFP2 has been described in uterine structural integrity (Li et al., Endocrinology, 152, 2474-2482 (2011)), as a female anti-apoptotic germ cell agent (Nef et al., Nat Genet, 22, 295-299 (1999); amd Spanel-Borowski et al., Mol Reprod Dev, 58, 281-286 (2001)), and as a therapeutic agent in wound healing at the ocular surface (Hampel et al., Endocrinology, 154, 2034-2045 (2013)). Importantly, the INSL3 overexpression transgenic model showed that the excess of INSL3 had no effect on survival, development (other than gonadal position), viability, or fertility of mutant mice (Adham et al., Mol Endocrinol, 16, 244-252 (2002)). The INSL3/RXFP2 system also has been observed in certain cancers, including prostate carcinoma and human thyroid carcinoma tissues (Esteban-Lopez et al., Journal of Endocrinology, 247 (1), R1-R12 (2020)).
To date, no small molecule agonists of RXFP2 have been reported in the literature. Thus, there remains an unmet need to provide small molecule compounds that activate the functional activity of RXFP2 to be used in various therapeutic methods, including treating osteoporosis, hypogonadism, and cancer.
The invention provides a compound of formula (I)
in which R1, R2, R3, R4, R5, X1, X2, X3, X4, and X5 are as described herein.
The small molecule compounds have been discovered to activate the functional activity of relaxin family peptide receptor 2 (RXFP2), thereby providing therapeutic treatments for a variety of disorders, such as a bone disorder, hypogonadism, cryptorchidism, polycystic ovary syndrome, cancer, infertility, or an ocular wound.

In any of the aspects herein, the phrase “salt” or “pharmaceutically acceptable salt” is intended to include nontoxic salts synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two. For example, an inorganic acid (e.g., hydrochloric acid, sulfuric acid, phosphoric acid, or hydrobromic acid), an organic acid (e.g., oxalic acid, malonic acid, citric acid, fumaric acid, lactic acid, malic acid, succinic acid, tartaric acid, acetic acid, trifluoroacetic acid, gluconic acid, ascorbic acid, methylsulfonic acid, or benzylsulfonic acid), an inorganic base (e.g., sodium hydroxide, potassium hydroxide, calcium hydroxide, magnesium hydroxide, or ammonium hydroxide), an organic base (e.g., methylamine, diethylamine, triethylamine, triethanolamine, ethylenediamine, tris(hydroxymethyl)methylamine, guanidine, choline, or cinchonine), or an amino acid (e.g., lysine, arginine, or alanine) can be used. Generally, nonaqueous media such as ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are typical. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 18th ed., Mack Publishing Company, Easton, PA, 1990, p. 1445, and Journal of Pharmaceutical Science, 66, 2-19 (1977). For example, they can be a salt of an alkali metal (e.g., sodium or potassium), alkaline earth metal (e.g., calcium), or ammonium of salt.

Extemporaneous injection solutions and suspensions can be prepared from sterile powders, granules, and tablets of the kind previously described.
The compound of formula (I) can be made into an injectable formulation. The requirements for effective pharmaceutical carriers for injectable compositions are well known to those of ordinary skill in the art. See Pharmaceutics and Pharmacy Practice, J. B. Lippincott Co., Philadelphia, Pa., Banker and Chalmers, eds., pages 238-250 (1982), and ASHP Handbook on Injectable Drugs, Toissel, 4th ed., pages 622-630 (1986).
Topically applied compositions are generally in the form of liquids (e.g., mouthwash), creams, pastes, lotions and gels. Topical administration includes application to the oral mucosa, which includes the oral cavity, oral epithelium, palate, gingival, and the nasal mucosa. In some aspects, the composition contains at least one active component and a suitable vehicle or carrier. It may also contain other components, such as an anti-irritant. The carrier can be a liquid, solid or semi-solid. In aspects, the composition is an aqueous solution, such as a mouthwash. Alternatively, the composition can be a dispersion, emulsion, gel, lotion or cream vehicle for the various components. In one aspect, the primary vehicle is water or a biocompatible solvent that is substantially neutral or that has been rendered substantially neutral. The liquid vehicle can include other materials, such as buffers, alcohols, glycerin, and mineral oils with various emulsifiers or dispersing agents as known in the art to obtain the desired pH, consistency and viscosity. It is possible that the compositions can be produced as solids, such as powders or granules. The solids can be applied directly or dissolved in water or a biocompatible solvent prior to use to form a solution that is substantially neutral or that has been rendered substantially neutral and that can then be applied to the target site. In aspects of the invention, the vehicle for topical application to the skin can include water, buffered solutions, various alcohols, glycols such as glycerin, lipid materials such as fatty acids, mineral oils, phosphoglycerides, collagen, gelatin and silicone based materials.

They also may be formulated as pharmaceuticals for non-pressured preparations, such as in a nebulizer or an atomizer.
The dose administered to the subject, particularly human and other mammals, in accordance with the present invention should be sufficient to affect the desired response. One skilled in the art will recognize that dosage will depend upon a variety of factors, including the age, condition or disease state, predisposition to disease, genetic defect or defects, and body weight of the subject. The size of the dose will also be determined by the route, timing and frequency of administration as well as the existence, nature, and extent of any adverse side-effects that might accompany the administration of a particular compound of formula (I) and the desired effect. It will be appreciated by one of skill in the art that various conditions or disease states may require prolonged treatment involving multiple administrations.
The inventive methods comprise administering an effective amount of a compound of formula (I) or a pharmaceutically acceptable salt thereof. An “effective amount” means an amount sufficient to show a meaningful benefit in an individual, e.g., promoting bone growth, reducing bone loss, maintaining bone density, increasing vertebrae trabecular number and/or thickness, inhibiting of glomerular cell proliferation, maintaining muscle density, increasing wound healing, increasing corneal healing, promoting testis descent, treating polycystic ovary syndrome (PCOS), treating cryptorchidism, promoting germ cell survival, promoting Leydig cell maturation, promoting at least one aspect of tumor cell cytotoxicity (e.g., inhibition of growth, inhibiting survival of a cancer cell, reducing proliferation, reducing size and/or mass of a tumor (e.g., solid tumor)), or treatment, healing, prevention, delay of onset, halting, or amelioration of other relevant medical condition(s) associated with a particular disorder. The meaningful benefit observed in the subject can be to any suitable degree (e.g., 10% or more, 20% or more, 30% or more, 40% or more, 50% or more, 60% or more, 70% or more, 80% or more, or 90% or more). In some aspects, one or more symptoms of the disorder (e.g., osteoporosis, hypogonadism, cancer) are prevented, reduced, halted, or eliminated subsequent to administration of a compound of formula (I) or a pharmaceutically acceptable salt and/or enantiomer thereof, thereby effectively treating the disorder to at least some degree.
Effective amounts may vary depending upon the biological effect desired in the individual, condition to be treated, and/or the specific characteristics of the compound of formula (I) or a pharmaceutically acceptable salt and/or enantiomer thereof, and the individual. In this respect, any suitable dose of the compound of formula (I) or a pharmaceutically acceptable salt and/or enantiomer thereof can be administered to the subject (e.g., human), according to the type of disorder to be treated. Various general considerations taken into account in determining the “effective amount” are known to those of skill in the art and are described, e.g., in Gilman et al., eds., Goodman and Gilman's: The Pharmacological Bases of Therapeutics, 8th ed., Pergamon Press, 1990; and Remington's Pharmaceutical Sciences, 17th Ed., Mack Publishing Co., Easton, Pa., 1990, each of which is herein incorporated by reference. The dose of the compound of formula (I) or a pharmaceutically acceptable salt and/or enantiomer thereof desirably comprises about 0.01 mg per kilogram (kg) of the body weight of the subject (mg/kg) or more (e.g., about 0.05 mg/kg or more, 0.1 mg/kg or more, 0.5 mg/kg or more, 1 mg/kg or more, 2 mg/kg or more, 3 mg/kg or more, 5 mg/kg or more, 10 mg/kg or more, 15 mg/kg or more, 20 mg/kg or more, 30 mg/kg or more, 40 mg/kg or more, 50 mg/kg or more, 75 mg/kg or more, 100 mg/kg or more, 125 mg/kg or more, 150 mg/kg or more, 175 mg/kg or more, 200 mg/kg or more, 225 mg/kg or more, 250 mg/kg or more, 275 mg/kg or more, 300 mg/kg or more, 325 mg/kg or more, 350 mg/kg or more, 375 mg/kg or more, 400 mg/kg or more, 425 mg/kg or more, 450 mg/kg or more, or 475 mg/kg or more) per day. Typically, the dose will be about 500 mg/kg or less (e.g., about 475 mg/kg or less, about 450 mg/kg or less, about 425 mg/kg or less, about 400 mg/kg or less, about 375 mg/kg or less, about 350 mg/kg or less, about 325 mg/kg or less, about 300 mg/kg or less, about 275 mg/kg or less, about 250 mg/kg or less, about 225 mg/kg or less, about 200 mg/kg or less, about 175 mg/kg or less, about 150 mg/kg or less, about 125 mg/kg or less, about 100 mg/kg or less, about 75 mg/kg or less, about 50 mg/kg or less, about 40 mg/kg or less, about 30 mg/kg or less, about 20 mg/kg or less, about 15 mg/kg or less, about 10 mg/kg or less, about 5 mg/kg or less, about 2 mg/kg or less, about 1 mg/kg or less, about 0.5 mg/kg or less, or about 0.1 mg/kg or less). Any two of the foregoing endpoints can be used to define a close-ended range, or a single endpoint can be used to define an open-ended range.

Mammals include, but are not limited to, the order Rodentia, such as mice, and the order Lagomorpha, such as rabbits. It is preferred that the mammals are from the order Carnivora, including Felines (cats) and Canines (dogs). It is more preferred that the mammals are from the order Artiodactyla, including Bovines (cows) and Swines (pigs) or of the order Perissodactyla, including Equines (horses). It is most preferred that the mammals are of the order Primates, Cebids, or Simioids (monkeys) or of the order Anthropoids (humans and apes). An especially preferred mammal is a human.
In an aspect, a compound of formula (I) or a pharmaceutically acceptable salt and/or enantiomer thereof activates the functional activity of (i.e., agonizes) relaxin family peptide receptor 2 (RXFP2). The RXFP2 activity can be measured by any suitable assay, including those described herein. Accordingly, the invention provides a method of activating the functional activity of RXFP2 in a cell comprising contacting the cell with the compound of formula (I) or a pharmaceutically acceptable salt and/or enantiomer thereof. The cell can be in vivo or ex vivo and can be from any suitable tissue whose cells express RXFP2. Suitable tissue includes, for example, bone, eye, muscle, ovary, uterus, testis, prostate, thyroid, muscle, brain, and combinations thereof.
Agonism of the INSL3/RXFP2 signaling pathway is considered a viable treatment of disorders associated with RXFP2, including mutations of RXFP2. Accordingly, the invention provides a method of treating a disorder mediated by RXFP2 in a subject comprising administering the compound of formula (I) or a pharmaceutically acceptable salt and/or enantiomer thereof to the subject. The disorder mediated by RXFP2 can be, for example, a bone disorder, hypogonadism, cryptorchidism, polycystic ovary syndrome (PCOS), cancer, infertility, or an ocular (eye) wound. The bone disorder can be, for example, osteoporosis, osteopenia, or osteogenesis imperfecta. The cancer can be, for example, testicular cancer, prostate cancer, or thyroid cancer.
In another aspect, the invention provides a method of growing (e.g., increasing the amount of) bone or muscle in a subject comprising contacting the subject with the compound of formula (I) or a pharmaceutically acceptable salt and/or enantiomer thereof. The term “growing” refers to the amount of bone or muscle that is increased relative to a control sample in which no compound of formula (I) is administered in the same time frame.

General Methods. All air or moisture sensitive reactions were performed under positive pressure of nitrogen or argon with oven-dried glassware. Anhydrous solvents such as dichloromethane (DCM), N,N-dimethylformamide (DMF), tetrahydrofuran (THF), acetonitrile (ACN), methanol (MeOH), and triethylamine (TEA) were purchased from Sigma-Aldrich (St. Louis, MO). Preparative purification was performed on a Waters semi-preparative HPLC system (Waters Corp., Milford, MA). The column used was a Phenomenex Luna C18 (5 micron, 30×75 mm; Phenomenex, Inc., Torrance, CA) at a flow rate of 45.0 mL/min. The mobile phase consisted of acetonitrile and water (each containing 0.1% trifluoroacetic acid). A gradient of 10% to 50% acetonitrile over 8 minutes was used during the purification. Fraction collection was triggered by ultraviolet (UV) detection at 220 nM. Analytical analysis was performed on an Agilent liquid chromatography/mass spectrometry (LC/MS) (Agilent Technologies, Santa Clara, CA). Method 1 (t1): A 7-minute gradient of 4% to 100% acetonitrile (containing 0.025% trifluoroacetic acid) in water (containing 0.05% trifluoroacetic acid) was used with an 8-minute run time at a flow rate of 1.0 mL/min. Method 2 (t2): A 3-minute gradient of 4% to 100% acetonitrile (containing 0.025% trifluoroacetic acid) in water (containing 0.05% trifluoroacetic acid) was used with a 4.5-minute run time at a flow rate of 1.0 mL/min. A Phenomenex Luna C18 column (3 micron, 3×75 mm) was used at a temperature of 50° C. Method 3 (t3): A 3-minute gradient 4% to 100% acetonitrile (containing 0.1% NH4OH in water) was used with a 4.5-minute run time at a flow rate of 1.0 mL/min. Method 4 (t4):−d4 A 3-minute gradient 4% to 100% acetonitrile (containing 0.1% NH4OH in water) was used with a 4.5-minute run time at a flow rate of 1.0 mL/min. Purity determination was performed using an Agilent diode array detector for Method 1, Method 2, Method 3, and Method 4. Mass determination was performed using an Agilent 6130 mass spectrometer with electrospray ionization in the positive mode (Method 1, Method 2, and Method 3) and in the negative mode for Method 4. 1H nuclear magnetic resonance (NMR) and 19F NMR spectra were recorded on Varian 400 MHz or 600 spectrometers (Agilent Technologies, Santa Clara, CA). Chemical shifts are reported in ppm with deuterated solvent (DMSO-d6) at 2.50 ppm, Acetic Acid-d4 at 2.03 ppm, CDCl3 at 7.26 and ACD-d4 at 1.96 ppm as internal standard reference chemical shifts for NMR sample solutions. All of the analogs tested in the biological assays had a purity of greater than 95% based on both analytical methods. High resolution mass spectrometry was recorded on Agilent 6210 Time-of-Flight (TOF) LC/MS system. Confirmation of molecular formula was accomplished using electrospray ionization in the positive mode with the Agilent Masshunter software (Version B.02). Chiral and racemic 1-(tert-butyl)-3-methyl piperazine-1,3-dicarboxylates (R([α]D20=−27 (c=1, CHCl3)), S [α]D20=+25 (c=1, CHCl3)), and the racemic compound were purchased from Combiblocks (Combi-Blocks, Inc. San Diego, CA). Chimeric receptor constructs were obtained from Dr Ross Bathgate (Florey Institute, Australia). The design of the plasmids was in accordance with the methods of Sudo et at. (The Journal of Biological Chemistry, 278(10), 7855-7862 (2002)), the contents of which are fully incorporated by reference.

The resultant reaction mixture was allowed to stir 18 hours at room temperature. The reaction mixture was poured into ethyl acetate (EtOAc) and washed twice with water. The organic layer was dried with Na2SO4 and concentrated in vacuo. The crude mixture was purified by flash column chromatography (silica gel, 0-50% EtOAc-hexanes) to afford the corresponding 1-(tert-butyl)-3-methyl 4-(5-bromo-2-((tert-iodo-2-((tert-butoxycarbonyl)amino)benzoyl)piperazine-1,3-dicarboxylates or 1-(tert-butyl)-3-methyl 4-(4-((tert-butoxycarbonyl)amino)-[1,1′-substituted-biphenyl]-3-carbonyl)piperazine-1,3-dicarboxylates.

This example demonstrates the agonist RXFP2 agonist activity of exemplary compounds of formula (I) in an aspect of the invention.
Compound efficacy and EC50 were determined by measuring cAMP induction in vitro. HEK293T cells stably expressing RXFP2 (HEK-RXFP2) produce cAMP when RXFP2 is activated, which can be measured in an antibody-based immunoassay utilizing a fluorescent readout (cAMP Gs HiRange Kit, PerkinElmer, Waltham, MA). HEK-RXFP2 cells were seeded in 96-well plates in serum-free DMEM and incubated overnight at 37° C., 5% CO2. Plates were then treated with a compound titration up to 25 μM or INSL3 control, in the presence of isobutylmethylxanthine phosphodiesterase inhibitor (IBMX) at 200 μM to amplify the cAMP signal, for 1 hour at 37° C., 5% CO2 before being processed as per kit instructions. Table 7 lists the efficacy and EC50 of compounds tested under different experimental conditions. Protocols were modified since more potent compounds had responses too high to measure under initial conditions. In condition (a), 20,000 cells were seeded per well in the 96 well plate, and efficacy was determined by normalizing the maximum compound cAMP response to the 1 nM INSL3 cAMP response (% Efficacy 1 nM INSL3 (a)). In condition (b), 10,000 cells were seeded per well, and compound response was normalized to the 1 nM INSL3 cAMP response (% Efficacy 1 nM INSL3 (b)). In condition (c), 7,500 cells were seeded per well, compound response was normalized to the 100 nM INSL3 cAMP response, and IBMX was omitted (% Efficacy 100 nM INSL3 (c)). A range is given when compounds were tested multiple times. Where compounds were tested under multiple experimental conditions, the EC50 listed for the corresponding condition is marked (a) through (c) to correlate. When EC50 could not be calculated from the dose-response curve, EC50 is listed as not determined (ND).
This example demonstrates the secondary luciferase cAMP screening of positive homogeneous time resolved fluorescence (HTRF) hits.
A confirmatory cAMP assay was done to eliminate false positives using a HEK293T-CRE-Luc cell line stably transfected with RXFP2 (HEK-CRE-Luc-RXFP2), as this cell line expresses luciferase under the control of the cAMP response element (CRE). Activation of the RXFP2 receptor increases intracellular cAMP levels, inducing luciferase transcription in the nucleus. Thus, luciferase activity in these cells is proportional to cAMP accumulation. For this assay, cells were seeded in 96-well flat-bottom opaque plates at 20,000 cells/well in 60 μL/well of serum-free DMEM medium and allowed to attach overnight at 37° C., 5% CO2. The next morning, cells were treated with 1 μL/well of compound (25 μM-0.21 nM), 1 μM forskolin, or DMSO vehicle. Cells were also treated with 4 μL of INSL3 (100-0.01 nM) (Phoenix Pharmaceuticals, Burlingame, CA) or vehicle serum-free DMEM. Cells were incubated with the treatments for 3 hours at 37° C., 5% CO2, then rested 30 minutes at room temperature for equilibration, after which 65 μL/well of substrate AMPLITE™ Luciferase Reporter Gene Assay Kit (AAT Bioquest, Sunnyvale, CA) was added. Plates were incubated for 40 minutes at room temperature protected from light, and then luciferase output was read on a CLARIOstar plate reader (BMG Labtech, Germany).
This example describes an HTRF cAMP counter-screen in HEK-RXFP1 cells in an aspect of the invention.
HEK293T cells stably transfected with RXFP1 (HEK-RXFP1) were used to test compound specificity towards the RXFP2 receptor using the HTRF Gs dynamic cAMP assay kit (PerkinElmer, Waltham, MA). This is a competitive immunoassay where a time-resolved fluorescence resonance energy (TR-FRET) signal is produced when exogenous d2-labeled cAMP (acceptor) binds to europium cryptate-conjugated anti-cAMP antibody (donor). No signal is produced when endogenous cAMP binds to the antibody. Thus, the TR-FRET signal is inversely proportional to the concentration of cAMP produced by the cells. The HTRF cAMP assay was carried out in the presence of isobutylmethylxanthine phosphodiesterase inhibitor (IBMX) at 200 μM to amplify the cAMP signal. For this assay, cells were seeded in 96-well flat-bottom opaque plates at 30,000 cells/well in 60 μL/well of serum-free DMEM medium and allowed to attach overnight at 37° C., 5% CO2. The next morning, cells were treated with 1 μL/well of compound (10 μM-1.2 nM), 1 μM forskolin, or DMSO vehicle. Cells were also treated with 4 μL of 10 nM Relaxin2 (Peprotech, Cranbury, NJ) as a positive control or vehicle (serum-free DMEM+IBMX). Plates were incubated for 1 hour at 37° C., 5% CO2, after which 16 μL/well of kit cAMP-d2 and 16 μL/well of anti-cAMP antibody were added as per manufacturer protocol. Cells were incubated for 1 hour at room temperature, and then the signal was read on a CLARIOstar plate reader (BMG Labtech, Germany).
This example demonstrates a PRESTO-Tango GPCRome counter-screen in transiently transfected HTLA cells in an aspect of the invention.
The PRESTO-Tango GPCRome assay, which measures G-protein coupled receptors (GPCR) mediated beta-arrestin recruitment, was used to perform a HTS of related GPCRs to study specificity and selectivity of the RXFP2 agonists. A total of 320 GPCR Tango constructs were tested. Each of the GPCR constructs used in the assay contained a FLAG tag, the GPCR gene of interest, a Vasopressin 2 C-terminal tail, the TEV protease cleavage site, and the tetracycline-controlled transactivator (tTA) transcription factor. The assay was performed using transiently transfected HTLA cells that stably express the beta-arrestin2-TEV protease fusion protein and a luciferase reporter gene under the control of the tTA transcription factor. Ligand activation of the transfected GPCR construct induces beta-arrestin translocation to the GPCR, where the tobacco etch virus (TEV) protease cleaves the tTA transcription factor, causing activation of luciferase transcription in the nucleus. Thus, luciferase activity in these cells is proportional to beta-arrestin translocation activity. For this assay, HTLA cells were seeded in Poly-L-Lys (PLL)-coated 384-well white clear-bottom plates at 10,000 cell/well in 40 μl/well DMEM supplemented with 10% FBS. Cells were incubated overnight at 37° C., 5% CO2 to allow them to attach. The next morning, cells were fed 10 μL/well of 50% FBS DMEM 1 hour before transfection. Cells were transfected with 20 ng of plasmid diluted in an equal volume of 0.25 M CaCl2) and HEPES ((4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) buffered saline (HBS) (50 mM HEPES, 280 mM NaCl, 10 mM KCl, 1.5 mM Na2HPO4, pH 7.00) in a total volume of 6 μl/well using a MICROLAB™ STAR (Hamilton, Reno, NV) with a 384-well pipetting head. After transfection, cells were incubated overnight at 37° C., 5% CO2. The next morning, medium was removed and replaced with 40 μl/well of fresh 1% FBS DMEM 2 hours before addition of treatments. Cells were treated with 10 μL/well of 10 μM compound diluted in 1% FBS DMEM and incubated overnight at 37° C., 5% C02. The following day, medium was removed and 20 μl/well of BrightGlo reagent (Promega, Madison, WI) diluted 1:20 with Tango assay buffer was added. Plates were incubated for 20 minutes at room temperature protected from light and the luminescence signal was read on a MicroBeta counter (PerkinElmer, Waltham, MA).
This example demonstrates a cytotoxicity assay in HEK293T and HCO cells in an aspect of the invention.
Cytotoxicity induced by the compounds in HEK293T cells and primary human calvarial osteoblasts (HCO) (ScienCell Research Laboratories, San Diego, CA) were tested using the CELLTITER-GLO™ Luminescent Cell Viability Assay (Promega, Madison, WI). This is a luminescence-based assay that determines viable cells by measuring cellular adenosine triphosphate (ATP) production. The luciferase enzyme requires ATP to catalyze the conversion of beetle luciferin to oxyluciferin and light. Thus, luciferase activity is proportional to ATP accumulation in the cells. For this assay, 96-well flat-bottom opaque plates seeded with HEK293T cells at 5,000 cells/well and HCO cells at 3,000 cells/well in 100 μL/well of growth medium (DMEM, 10% FBS, 1× Penicillin/Streptomycin). After incubating overnight at 37° C., 5% CO2 to allow attachment, cells were treated with 1 μL/well of compound (25-0.1 μM) or DMSO vehicle and incubated an additional 24 hours. Then cells were equilibrated for 30 minutes at room temperature and 100 μL/well of CELLTITER-GLO™ Reagent was added. Plates were placed on an orbital shaker for 2 minutes and incubated at room temperature for 10 minutes to stabilize the luminescent signal, which was read immediately after on a CLARIOstar plate reader (BMG Labtech, Germany).
This example demonstrates activation of mouse RXFP2 in transiently transfected HEK-CRE-Luc cells in an aspect of the invention.
It was of interest if the RXFP2 agonists of formula (I) activate the mouse RXFP2 receptor. HEK-CRE-Luc cells transiently transfected with mouse RXFP2 were used to test agonist activity by measuring induction of cAMP. For this assay, cells were seeded in 6-well flat-bottom clear plates at 0.6 million cells/well in 2 mL/well of growth medium (DMEM, 10% FBS, 1× Pen/Strep) and allowed to attach overnight at 37° C., 5% CO2. The next morning, cells were transfected with 2 μg of plasmid (human or mouse RXFP2) and 6 μL of Lipofectamine2000 (Invitrogen, Waltham, MA) in a total volume of 200 μl/well OPTI-MEM™ I (Thermo Fisher, Waltham, MA) reduced serum medium and incubated an additional 24 hours. The transfected cells were then harvested and seeded in 96-well flat-bottom opaque plates at 30,000 cells/well in 60 μL/well of serum-free DMEM medium and incubated overnight to attach. The next morning, cells were treated with 1 μL/well of compound (10 μM-1.2 nM), 2 μM forskolin, or DMSO vehicle, and with 4 μL of positive control INSL3 (100-0.01 nM) (Phoenix Pharmaceuticals, Burlingame, CA) or vehicle serum-free DMEM. Cells were incubated with the treatments for 3 hours at 37° C., 5% CO2, then rested 30 minutes at room temperature for equilibration, after which 65 μL/well of substrate AMPLITE™ Luciferase Reporter Gene Assay Kit (AAT Bioquest, Sunnyvale, CA) were added. Plates were incubated for 40 minutes at room temperature protected from light, and the signal was read on a CLARIOstar plate reader (BMG Labtech, Germany).
This example shows the characterization of agonist-receptor interactions using an INSL3 antagonist in an aspect of the invention.
Previous publications have characterized the INSL3/RXFP2 binding model, showing that the B-chain of INSL3 binds with high affinity to the extracellular leucine-rich repeat (LRR) domain of RXFP2. To determine if the RXFP2 agonists interact with the receptor in a similar manner, an INSL3 antagonist (INSL3 B dimer) was used to co-treat HEK-RXFP2 cells with RXFP2 agonists or INSL3 and measure induction of cAMP using the HTRF assay. This INSL3 antagonist consists of a dimer formed by two INSL3 B-chains and has been shown to bind the LRR domain of RXFP2 without inducing a cAMP response. The HTRF cAMP assay was carried out in the presence of 200 μM IBMX to amplify the cAMP signal. For this assay, cells were seeded in 96-well flat-bottom opaque plates at 7,500 cells/well in 60 μL/well of serum-free DMEM medium and allowed to attach overnight at 37° C. and 5% CO2. The next morning, cells were treated with 2 μL of INSL3 B dimer antagonist (10 μM-0.21 nM) and 2 μL of 30 nM INSL3 or 4 μL of vehicle (serum-free DMEM+IBMX). Cells were also treated with 1 μL/well of 0.28 μM compound, 2 μM forskolin, or DMSO vehicle. Cells were incubated for 1 hour at 37° C., 5% CO2, after which kit cAMP-d2 and anti-cAMP antibody were added as previously described. Plates were incubated for 1 hour at room temperature, and then the signal was read on a CLARIOstar plate reader (BMG Labtech, Germany).
This example shows the characterization of agonist-receptor interactions using chimeric receptors in an aspect of the invention.
To further investigate the involvement of the RXFP2 extracellular and transmembrane domains in agonist activation of the receptor, two complementary chimeras were created using the RXFP1 receptor, which is not activated by the agonists of formula (I), to transiently transfect HEK293T cells and measured changes in cAMP induction using the HTRF assay.
Chimeric receptors were generated by IN-FUSION™ (Takara Bio USA, Inc., San Jose, CA) mutagenesis using full-length human RXFP1 and RXFP2 receptor constructs. Polymerase chain reaction (PCR) was performed using PfuTurbo high-fidelity DNA polymerase (Agilent Technologies, Santa Clara, CA) and overlapping primers with at least 15 bp sequence homology within the fusion site. PCR products were digested with Dpnl restricton enzyme at 37° C. overnight, run on a 0.8% agarose gel and purified using the GENEJET™ Gel extraction kit (Thermo Scientific, Waltham, MA). The purified DNA fragments were then ligated into the BamHI and XhoI pre-digested pcDNA3.1™/Zeo(+) AmpR mammalian expression vector using the In-Fusion HD enzyme premix (Clontech, Mountain View, CA) at 50° C. for 15 minutes, and the resulting product was used to transform Stellar competent cells (Takara Bio USA, Inc., San Jose, CA). The clones were fully sequenced to confirm the correct fusion of both receptor fragments. Chimera RXFP2-1 contained the extracellular domain of RXFP2 and the transmembrane domain of RXFP1. Accordingly, chimera RXFP1-2 contained the extracellular domain of RXFP1 and the transmembrane domain of RXFP2.
Induction of cAMP Signaling in Transiently Transfected HEK293T Cells
The chimeric receptors were used to transiently transfect HEK293T cells and measure differences in cAMP induction by INSL3 and the compound of Example 187. HEK293T cells were seeded in 6-well flat-bottom clear plates at 0.5 million cells/well in 2 mL/well of growth medium (DMEM, 10% FBS, 1× Pen/Strep) and allowed to attach overnight at 37° C. and 5% CO2. The next morning, cells were transfected with 2 μg of plasmid (chimeric receptors, WT RXFP2, or WT RXFP1) and 6 μl of Lipofectamine2000 (Invitrogen, Waltham, MA) in a total volume of 200 μl/well OPTI-MEM™ I (Thermo Fisher, Waltham, MA) reduced serum medium and allowed to incubate an additional 24 hours. The next day, transfected cells were seeded in 96-well flat-bottom opaque plates at 30,000 cells/well in 60 μL/well of serum-free DMEM medium and allowed to attach overnight at 37° C. at 5% CO2. The next morning, cells were treated with 1 μL/well of compound (25 μM-0.25 nM), 2 μM forskolin, or DMSO vehicle. Cells were also treated with 4 μL of positive control INSL3 (100-0.01 nM), Relaxin2 (100-10 nM), or vehicle (serum-free DMEM+IBMX). Plates were incubated for 1 hour at 37° C. and 5% CO2, after which kit cAMP-d2 and anti-cAMP antibody were added as previously described. Cells were incubated for 1 hour at room temperature, and then the signal was read on a CLARIOstar plate reader (BMG Labtech, Germany). Table 9 shows the changes in cAMP response of the chimeras in comparison to the wild type (WT) receptors after treatment with representative RXFP2 agonist of Example 187 and positive control INSL3 (means±SEM of 3 independent experiments). The compound of Example 187 and INSL3 efficacies for each receptor were normalized to 2 μM forskolin cAMP response as 100% activity and their Emax and EC50 values are reported in Table 9.
The results in Table 9 showed that the chimera RXFP2-1 had no response to the compound of Example 187 but responded to INSL3 at levels comparable to WT RXFP2. On the contrary, the RXFP1-2 chimera did not respond to INSL3 but responded to the compound of Example 187 at levels comparable to WT RXFP2, and to Relaxin at levels comparable to WT RXFP1. These results suggest that the extracellular domain of RXFP2 is not involved in the compound of Example 187's activation of the receptor, and points to the transmembrane domain as the primary region for agonist interaction.
All receptor constructs contain a FLAG tag that allows measurement of receptor expression on the cell surface via flow cytometry. For this assay, HEK293T cells were seeded in 6-well flat-bottom clear plates at 0.6 million cells/well in 2 mL/well of growth medium (DMEM, 10% FBS, 1× Pen/Strep) and allowed to attach overnight at 37° C. and 5% CO2. The next morning, cells were transfected with 2 μg of plasmid (empty vector pcDNA3.1, chimeric receptors, WT RXFP2 or WT RXFP1) and 6 μL of Lipofectamine2000 (Invitrogen) in a total volume of 200 μl/well OPTI-MEM™ I (Thermo Fisher, Waltham, MA) reduced serum medium and incubated at 37° C. and 5% CO2. Twenty-four hours after transfection, cells were harvested in 1.5 mL/well of phosphate-buffered saline (PBS)+5 mM ethylenediaminetetraacetic acid (EDTA). 750 μL of the cell suspension was used for surface staining and 750 μL permeabilized for total staining. Cells were centrifuged at 2,000×rpm for 3 minutes, resuspended in 400 μl PBS and fixed for 10 minutes in 3.7% formaldehyde. Cells were centrifuged, washed twice with 0.5 mL of stain buffer for surface detection (2% fetal bovine serum (FBS), trsi-buffered saline (TBS), and 1 mM CaCl2)) or with permeabilization buffer for total staining (stain buffer+0.2% polysorbate 20 (TWEEN™ 20)) and incubated with 0.5 μg anti-FLAG M1 Ab (Sigma-Aldrich, St. Louis, MO) for 1 hour at 4° C. in 100 μL of the respective buffer. Cells were washed again with 1 mL of stain or permeabilization buffer and incubated with 1 μg ALEXA FLUOR™ 488 goat anti-mouse IgG (Invitrogen, Waltham, MA) for 20 minutes at 4° C. protected from light in 100 μL of the respective buffer. Cells were washed a final time with 1 mL of the respective buffer and resuspended in 300 μl stain buffer for analysis on an ACCURI™ C6 flow cytometer (BD Biosciences, Franklin Lakes, NJ). Cells transfected with the empty vector were used to establish background staining.
The biological activity of the RXFP2 agonists was tested in primary HCO cells (ScienCell Research Laboratories, San Diego, CA) by measuring their ability to induce osteoblast mineralization. A fluorescent-based assay (OSTEOIMAGE™ Mineralization Assay, Lonza, Switzerland) was used that measures hydroxyapatite, which is the main mineral component of bone. For this assay, HCO cells were seeded in 0.1% gelatin-coated 96 well black-walled flat-bottom clear plates at 7,000 cells/well in 100 μL/well of growth medium (DMEM, 10% FBS, 1× Pen/Strep) and allowed to attach overnight at 37° C. and 5% CO2. The next day, growth medium was changed to 100 μL/well of mineralization medium (growth medium+10 mM β-glycerophosphate, 50 μg/ml ascorbic acid, 10 nM dexamethasone), along with the respective treatments. Cells were treated with 1 μL/well of compound (1, 3, or 5 μM) or vehicle (serum-free DMEM, 0.05% DMSO). Medium and treatments were replaced every 2-3 days and cells were incubated at 37° C. and 5% CO2 for 14 days. Hydroxyapatite deposits were evaluated using the OSTEOIMAGE™ Mineralization Assay (Lonza, Switzerland). At treatment day 14, cells were rested 30 minutes at room temperature for equilibration, washed with 200 μL/well PBS, and fixed in 100 μL/well 4% formaldehyde for 15 minutes. Cells were washed once with 200 μL/well assay wash buffer and 100 μL/well of assay staining reagent was added as per manufacturer's protocol. Cells were incubated at room temperature for 30 minutes, protected from light. After staining, cells were washed 3 times with 200 μL/well wash buffer and wells were filled with a final 200 μL/well wash buffer. Mineralization was quantified using a CLARIOstar plate reader (BMG Labtech, Germany) and representative images of the hydroxyapatite bone-like nodules were captured using a fluorescence microscope (Nikon Eclipse TS100 attached to an Olympus DP70 camera).
This example shows the characterization of agonist biological activity and specificity in vivo in an aspect of the invention.
The role of INSL3 and RXFP2 in gubernaculum development for the initial transabdominal descent of the testis during embryogenesis has been widely characterized in Insl3−/− and Rxfp2−/− mouse models of cryptorchidism. At embryonic day 14.5, INSL3 starts driving gubemaculum development for the transabdominal stage of testicular descent in males, which is finalized by embryonic day 17.5. Representative histological sections of the developed male gubemaculum at embryonic day 18.5 were taken. The gubernaculum is composed of the gubernacular bulb and cord, and it has begun invagination into the abdominal wall in preparation for the inguinoscrotal stage of testicular descent, which will finalize after birth. In female mice, there is no production of INSL3 during embryogenesis, therefore the gubernaculum does not develop but remains present as a vestigial structure. The hypothesis for our experiment is that by injecting pregnant females with the RXFP2 agonists during this embryonic development window, gubemaculum development could be induced in female embryos, which has been previously shown in female embryos overexpressing INSL3.

The pharmacokinetic parameters for (S)-8-(3,5-bis(trifluoromethyl)phenyl)-2-(2-(2-iodo-4-(trifluoromethoxy)phenoxy)acetyl)-1,3,4,12a-tetrahydrobenzo[e]pyrazino[1,2-a][1,4]diazepine-6,12 (2H, 11H)-dione (KJW012-055), as prepared in Example 187, were measured in female C57/BL6 mice. The compound was formulated with a carrier comprising 75% polyethylene glycol (PEG) 300 and 25% of 40% aq. 2-hydroxypropyl-beta-cyclodextrin (HPBCD). The results are shown in Table 10.
This example shows the study of the RXFP2 agonist of Example 187's bone anabolic role in vivo in an aspect of the invention.
Eight week-old while-type C57BL/6J female mice (Jackson Laboratory) were randomly allocated into 2 treatment groups (vehicle or compound). Mice were treated every other day (Monday, Wednesday, and Friday) with RXFP2 agonist of Example 187 or vehicle formulation (75% PEG 300±25% of 40% aq. HPBCD) for a total of 8 weeks by oral gavage at a concentration of 10 mg/kg using 18G, 1.5-inch, 2 mm ball flexible polytetrafluoroethylene (PTFE) sterile plastic feeding needles. Mice were anesthetized with 2% isoflurane for less than 3 minutes before administrating the treatments to prevent disserts and esophageal lesions. At the end of the treatment, mice were euthanized by isoflurane inhalation overdose, and the lumbar spine was collected, cleaned from muscle tissue, wrapped in a PBS-soaked gauze and frozen at −20° C. until use. All samples were shipped to University of Arkansas for Medical Sciences (UAMS) for analysis. Frozen L3 vertebral bodies were allowed to thaw for at least 2 hours at room temperature before scanning on a Scanco 40 instrument (Scanco Medical, Switzerland) using a slice resolution of 12 μm isotropic voxel size, effective energy of 55 kVp, X-ray tube current of 114 mA, and 200 ms integration time. For the trabecular bone quantification of the L3 vertebrae, the region of interest for analysis comprised the entire vertebral body, including the maximum number of slices possible between both growth plates, applying a grayscale threshold (lower threshold 220, upper threshold 1000) and Gaussian noise filter (sigma 0.8, support 1).
