Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 11/087,051 filed Mar. 22, 2005 and claims benefit of U.S. Application No. 60/555,945, filed on Mar. 24, 2004, the disclosure of which is incorporated by reference herein in its entireties.

FIELD OF THE INVENTION

This invention relates to agonists and antagonists of the progesterone receptor, their preparation and their use as progesterone receptor modulators.

BACKGROUND OF THE INVENTION

Intracellular receptors (IR) form a class of structurally related gene regulators known as “ligand dependent transcription factors” (Mangelsdorf, D. J. etc. Cell, 83, 835, 1995). The steroid receptor family is a subset of the IR family, including progesterone receptor (PR), estrogen receptor (ER), androgen receptor (AR), glucocorticoid receptor (GR), and mineralocorticoid receptor (MR).
The natural hormone, or ligand, for the PR is the steroid progesterone. Synthetic compounds, such as medroxyprogesterone acetate or levonorgestrel, can also serve as PR ligands. Once a ligand is present in the fluid surrounding a cell, it passes through the membrane via passive diffusion, and binds to the IR to create a receptor/ligand complex. This complex binds to specific gene promoters present in the cell's DNA. Once bound to the DNA the complex modulates the production of mRNA and the protein encoded by that gene.
A compound that binds to an IR and mimics the action of the natural hormone is termed an agonist, whilst a compound which inhibits the effect of the hormone is an antagonist.
PR agonists (natural and synthetic) are known to play an important role in the health of women. PR agonists are used in birth control formulations, either along or in the presence of an ER agonist. ER agonists are used to treat the symptoms of menopause, but have been associated with a proliferative effect on the uterus which can lead to an increased risk of uterine cancers. Co-administration of a PR agonist reduces/ablates that risk.
PR antagonists may also be used in contraception. In this context they may be administered alone (Ulmann, et al., Ann. N.Y. Acad. Sci., 261, 248, 1995), in combination with a PR agonist (Kekkonen, et al, Fertility and Sterility, 60, 610, 1993) or in combination with a partial ER antagonist such as tamoxifen (U.S. Pat. No. 5,719,136).
PR antagonists may also be useful for the treatment of hormone dependent breast cancers (Horwitz, et al, Horm. Cancer, 283, 1996, pub: Birkhaeuser, Boston, Mass., ed. Vedeckis) as well as uterine and ovarian cancers. PR antagonists may also be useful for the treatment of non-malignant chronic conditions such as uterine fibroids (Murphy, et al, J. Clin. Endo. Metab., 76, 513, 1993) and endometriosis (Kettel, et al., Fertility and Sterility, 56, 402, 1991).
PR antagonists may also be useful in hormone replacement therapy for post menopausal patients in combination with a partial ER antagonist such as tamoxifen (U.S. Pat. No. 5,719,136).
PR antagonists, such as mifepristone and onapristone, have been shown to be effective in a model of hormone dependent prostate cancer, which may indicate their utility in the treatment of this condition in men (Michna, et al, Ann. N.Y. Acad. Sci., 761, 224, 1995).
PR ligands have been described, for example, in Zhi, et al, (Bioorg. & Med. Chem. Lett. 10, 415, 2000 and J. Med. Chem., 41, 291, 1998), Tegley, et al (J. Med. Chem. 41, 4357, 1998), Combs, et al. (J. Med. Chem., 38, 4880, 1995), Perlman, et. al. (Tet. Letters, 35, 2295, 1994), Hamann, et al (Ann. N.Y. Acad. Sci., 761, 383, 1995), Chen, et al (Chen, et al, POI-37, 16^thInt. Cong. Het. Chem., Montana, 1997), Kurihari, et. al., described the PR ligand 12 (J. Antibiotics, 50, 360, 1997).
Zhang, et al., described several PR modulators (U.S. Pat. Nos. 6,432,949, 6,380,235, and 6,358,948). Other PR modulators are described in Fensome, et al. (U.S. Pat. Nos. 6,391,907 and 6,355,648), Santilli, et al (U.S. Pat. No. 6,306,851), Zhang, et al. (U.S. Pat. No. 6,369,056), Ullrich, et al. (U.S. Pat. No. 6,417,214), and Collins, et al. (U.S. Pat. Nos. 6,407,101 and 6,339,098).
Certain 4,1-benzoxazepinones are disclosed in the art. PCT Patent Application WO 99/11635 describes the use of some 5,5-disubstituted-1,5-dihydro-4,1-benzoxazepinones as HIV reverse transcriptase inhibitors.

The compounds of the present invention can be synthesized following the schemes described below or variations thereof as appreciated by those of skill in the art.
Scheme I illustrates a general synthesis of the compounds of the present invention. The 7-aryl (R₆) group was assembled via a coupling reaction such as Suzuki coupling reaction and is critical to the PR activity of compounds in the present invention. As illustrated in Scheme I, access to ketones 2 can be achieved by reaction of an appropriately substituted anthranilic acids 1 with a suitable organo lithium reagent. The reaction can be executed in an aprotic solvent including but not limited to THF or diethyl ether at a suitable temperature such as 0° C. or room temperature under a blanket of inert atmosphere such as nitrogen or argon. To prevent the formation of carbinol side products, a reversing quenching procedure (pouring the reaction mixture to a diluted aqueous acidic solution such as hydrogen chloride solution) is preferred. An alternative way to work up the reaction included but not limited to an addition of trialkylsilyl chloride or equivalent to the reaction before quenching the reaction mixture with a diluted aqueous acidic solution. Treatment of ketones 2 to give carbinols 3 is effected with a suitable organo metallic reagent including but not limited to Grignard or lithium reagents. The reaction can be performed in an aprotic solvent such as diethyl ether or THF at low temperature ranging from −78° C. to room temperature under an inert atmosphere such as argon or nitrogen. Formation of amide 4 can be achieved by treatment of carbinols 3 with an appropriate acylation reagent including but not limited to substituted chloro or bromoacetyl chloride or bromide. A suitable base such as triethyl amine, Hünig's base, potassium carbonate, or sodium carbonate and an aprotic solvent including but not limited to THF or diethyl ether can be used and the reaction temperature ranges from −78° C. to room temperature under an inert atmosphere such as argon or nitrogen. The ring closure to 5 can be effected by treatment of 4 with a suitable base such as sodium hydride, potassium carbonate, or triethyl amine. The reaction can be carried out in an aprotic solvent such as DMF, HMPA, or THF at the temperature ranging from 0° C. to room temperature. The coupling product 6 from 5 can be effected by a number of coupling reactions such as Suzuki and Stille procedures. These reactions are commonly performed in the presence of transition metallic catalyst, e.g., palladium or nickel complex often with phosphino ligands, e.g., Ph₃P, dppf, or dppe. Under this catalytic condition, an appropriately substituted nucleophilic reagent, e.g., aryl boronic acid, arylstannane, or aryl zinc compound, can be coupled with 5 to produce the compounds of the present invention, 7-aryl benzoxazepinones 6. The commonly used bases in the reaction include but not limited to sodium bicarbonate, sodium carbonate, potassium phosphate, barium carbonate, cesium fluoride, and potassium acetate. The most commonly used solvents in these reactions include benzene, toluene, DMF, isopropanol, ethanol, DME, and ether. The coupling reaction is generally executed under an inert atmosphere such as nitrogen or argon at temperatures ranging from room temperature to 95° C. In the case when the 7-aryl boronic acid is not available, the 7-halogen of 5 can be converted to the borate or stannane, which can be coupled with an appropriate aryl halide such as aryl bromide or aryl iodide using any coupling reaction described above.
Scheme IA describes a general synthesis of 7-(5-cyanopyrrol-2-yl)benzoxazepinones. An appropriately protected pyrrole moiety was coupled with 5 to yield 7 using the coupling procedure described above. Cyanation of pyrrole moiety at 5′-position can be readily effected by treatment of 7 with a suitable cyanating reagent such as chlorosulfonyl isocyanate in a non-protic solvent including but not limited to THF. When chlorosulfonyl isocyanate is used, the complex was formed and DMF can be used to break up the complex to install cyano moiety on the 5′-position of pyrrole ring. The reaction can be effected at −78° C. under an inert atmosphere such as nitrogen or argon and then treated with DMF to yield 8. There are other means known to those of skill in the art to install cyano moiety on the pyrrole ring including but not limited to a coupling reaction of cyano group to the pyrrole moiety catalyzed by a transition metal. In this procedure, the pyrrole moiety is substituted with bromine, iodine, or triflate serving as a leaving group to effect the coupling with cyano nucleophile. Removal of protecting group from 1′-position of pyrrole can be effected via various means depending on the nature of protecting group by ones of skill in the art. For example, Boc group can be removed by a number of conditions. These include ones such as treatment of 8 with base or acid or by thermo condition of simply heating neat material of 8 under an inert atmosphere such as nitrogen or argon at high temperature such as 165° C. to give the unprotected compounds of the present invention 9. Transformation at the 1′-position of pyrrole moiety included but not limited to alkylation and acylation. The alkylation such as methylation of the 1′-position on the pyrrole moiety to give 10 can be effected by treatment of 9 with an appropriate methylating reagent such as iodomethane. An aprotic solvent such as DMF and a suitable base such as potassium carbonate or potassium bicarbonate are often used and reaction is executed at 0° C. to room temperature.
Scheme II described an alternative route leading to ketones 2 by treatment of an appropriately substituted Weinreb amide 11 with organo metallic reagents such as Grignard or lithium reagents. The reaction can be most effectively executed in a suitable nonprotic solvent including but not limited to THF or diethyl ether at the temperature ranging from −78° C. to 0° C. under an inert atmosphere such as nitrogen or argon. The Weinreb amide 11 can be effected by the reaction of an appropriately substituted isatoic anhydride with N,O-dimethylhydroxylamine hydrochloride salt in a protic solvent such as ethanol or methanol at reflux.
Scheme III illustrates an alternative procedure for preparation of the symmetrical carbinaol 3. The substituted anthranilic acids can be treated with Grignard reagent to give 3. When the ester is used, both Grignard and organo lithium species can be used to effect the formation of carbinols 3 in good yield. The commonly used solvent in this transformation is an aprotic solvent including but not limited to THF and diethyl ether. The reaction can be executed at the temperature ranging from −78° C. to room temperature under an inert atmosphere such as argon or nitrogen.
Amino carbinol 3 can also be effected as illustrated in Scheme IV. A substituted aniline is protected with a suitable protecting group to give 13. The t-butoxylcarbonyl protecting group is preferred but other protecting groups including but not limited to t-butylcarbonyl and acetyl aniline can be used. The protected aniline 13 is treated with a suitable organo lithium base such as n-butyllithium and then quenched with a suitable ketone to afford n-protected amino carbinol. The reaction is executed in an aprotic solvent such as diethyl ether or THF at −78° C. under an inert atmosphere such as argon or nitrogen. Removal of the protecting group to give carbinol 3 can be effected by a number of ways known to those of skill in the art.
Scheme V depicts an alternative approach for the preparation of 7-pyrrolyl benzoxazepinone 7. A benzoxazepinone 5 is converted into a suitable nucleophile such as borate species by means well known by those of skill in the art. For example, the borate moiety can be effected by a boration procedure catalyzed by a transition metal similar to one reported by Murata et al. (M. Murata et al., J. Org. Chem., 62, 6458-6459, 1997). The borate 14 is then coupled with a suitable pyrrole such as a protected 2-bromo- or 2-iodopyrrole using the procedure described above for the preparation of 7 in Scheme IA.
Scheme VI illustrates another approach for synthesizing compounds in the present invention. Ketone 2 can be coupled with aryl moiety to give 15 using the coupling procedure described above. Following the procedures described in Scheme I, compounds 6 of the present invention can be effected in a multi-step synthesis.
The preparation of 7-aryl benzoxazepin-2-thione 16, the compounds of present invention, is depicted in Scheme VII. The transformation of 7-aryl benzoxazepinone 6 into 16 can be often effected using a sulfur reagent including but not limited to Lawesson's reagent or phosphorus pentasulfide in a suitable solvent such as toluene, chlorobenzene, or xylene at about 120° C. under nitrogen or argon.
Scheme VIII illustrates a synthesis of 7-aryl benzoxazepines. Benzoxazepinones 5 can be readily reduced to produce 17 by a suitable reducing reagent including but not limit to lithium aluminum hydride in an aprotic solvent such as THF at the ambient temperature under a blanket of inert atmosphere such as nitrogen or argon. Coupling of 17 with various aryl boronic acids using the coupling protocols described in Scheme I can readily effect the compounds of the present invention, 7-aryl benzoxazepines (18). Following the similar procedures described in Scheme IA, benzoxazepines substituted with 7-pyrrole moiety can be prepared.
A general synthesis of 7-aryl benzodiazepinones is depicted in Scheme IX. Ring closure of ketone 2 to benzodiazepinones 19 can be effected by condensing 2 with a suitable glycine ester or its derivatives in an aprotic solvent such as pyridine or toluene at reflux under nitrogen or argon. Addition of organo metallic reagent at position-5 can be difficulty without the activation of 4-nitrogen. In this regard, compound 19 can be readily alkylated and activated to give 20 by an appropriate alkylating reagent such as alkyl iodide in a suitable solvent such as acetonitrile under nitrogen or argon. Addition of an appropriate organo metallic reagent such as alkyllithium or Grignard reagent at position-5 to yield 21 can be easily achieved in an aprotic solvent such as diethyl ether or THF from ambient temperature to boiling point of the solvent under nitrogen or argon. In a similar manner as mentioned in Scheme I, the coupling reaction can be most efficiently used to convert 21 to the compounds of the present invention, 7-aryl benzodiazepinones (22). Following the procedure described in Scheme VII, 7-aryl benzodiazepin-2-thiones (23), the compounds of the present invention, can be readily effected.
Scheme X describes a synthesis of 7-aryl benzoazepinones. Aryl ketone 24, which can be readily prepared from the appropriately substituted arenes and lactones via Friedel-Crafts reactions, can be converted to benzoazepinones 25 by reacting with hydroxylamine (Beckmann rearrangement) under an acidic condition. Benzoazepinones 25 can also be prepared by treatment of 24 with sodium azide under acidic conditions (Schmidt rearrangement). 7-Bromobenzoazepinones 26 can be effected by treatment of 25 with bromine and a suitable base such as sodium acetate in an acidic solvent such as acetic acid at 0° C. to the ambient temperature. The compounds of present invention, 7-aryl benzoazepinones (27), can be produced most efficiently from 26 and a suitable substituted arene nucleophile by a coupling reaction such as ones described in Scheme I.
Using the procedure illustrated in Scheme VII, 7-aryl benzoazepin-2-thiones (28), claimed in the presentation invention, can be prepared.

These salts include, but are not limited to, the following salts with inorganic acids such as hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid and, as the case may be, such organic acids as acetic acid, oxalic acid, succinic acid, and maleic acid. Other salts include salts with alkali metals or alkaline earth metals, such as sodium, potassium, calcium or magnesium in the form of esters, carbamates and other conventional “pro-drug” forms, which, when administered in such form, convert to the active moiety in vivo.

When the compounds are employed for the above utilities, they may be combined with one or more pharmaceutically acceptable carriers or excipients, for example, solvents, diluents and the like, and may be administered orally in such forms as tablets, capsules, dispersible powders, granules, or suspensions containing, for example, from about 0.05 to 5% of suspending agent, syrups containing, for example, from about 10 to 50% of sugar, and elixirs containing, for example, from about 20 to 50% ethanol, and the like, or parenterally in the form of sterile injectable solutions or suspensions containing from about 0.05 to 5% suspending agent in an isotonic medium. Such pharmaceutical preparations may contain, for example, from about 25 to about 90% of the active ingredient in combination with the carrier, more usually between about 5% and 60% by weight.
The effective dosage of active ingredient employed may vary depending on the particular compound employed, the mode of administration and the severity of the condition being treated. However, in general, satisfactory results are obtained when the compounds of the invention are administered at a daily dosage of from about 0.5 to about 500 mg/kg of animal body weight, preferably given in divided doses two to four times a day, or in a sustained release form. For most large mammals, the total daily dosage is from about 1 to 100 mg, preferably from about 2 to 80 mg. Dosage forms suitable for internal use comprise from about 0.5 to 500 mg of the active compound in intimate admixture with a solid or liquid pharmaceutically acceptable carrier. This dosage regimen may be adjusted to provide the optimal therapeutic response. For example, several divided doses may be administered daily or the dose may be proportionally reduced as indicated by the exigencies of the therapeutic situation.
These active compounds may be administered orally as well as by intravenous, intramuscular, or subcutaneous routes. Solid carriers include starch, lactose, dicalcium phosphate, microcrystalline cellulose, sucrose and kaolin, while liquid carriers include sterile water, polyethylene glycols, non-ionic surfactants and edible oils such as corn, peanut and sesame oils, as are appropriate to the nature of the active ingredient and the particular form of administration desired. Adjuvents customarily employed in the preparation of pharmaceutical compositions may be advantageously included, such as flavoring agents, coloring agents, preserving agents, and antioxidants, for example, vitamin E, ascorbic acid, BHT and BHA.
The preferred pharmaceutical compositions from the standpoint of ease of preparation and administration are solid compositions, particularly tablets and hard filled or liquid-filled capsules. Oral administration of the compounds is preferred.
These active compounds may also be administered parenterally or intraperitoneally. Solutions or suspensions of these active compounds as a free base or pharmacologically acceptable salt can be prepared in water suitably mixed with a surfactant such as hydroxypropylcellulose. Dispersions can also be prepared in glycerol, liquid, polyethylene glycols and mixtures thereof in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.
The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form must be sterile and must be fluid to the extent that easy syringe ability exits. It must be stable under conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacterial and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol (e.g., glycerol, propylene glycol and liquid polyethylene glycol), suitable mixtures thereof, and vegetable oil.
The present invention may be further understood by the following non-limiting examples.

Pharmacology

(1) T47D Cell Proliferation Assay

Objective:

Determination of progestational and antiprogestational potency by using a cell proliferation assay in T47D cells. A compound's effect on DNA synthesis in T47D cells is measured.

Methods:

A. Reagents:

Growth medium: DMEM:F12 (1:1) (GIBCO, BRL) supplemented with 10% (v/v) fetal bovine serum (not heat-inactivated), 100 U/ml penicillin, 100 mg/ml streptomycin, and 2 mM GlutaMax (GIBCO, BRL).
Treatment medium: Minimum Essential Medium (MEM) (#51200-038GIBCO, BRL) phenol red-free supplemented with 0.5% charcoal stripped fetal bovine serum, 100 U/ml penicillin, 200 mg/ml streptomycin, and 2 mM GlutaMax (GIBCO, BRL).

B. Cell Culture:

Stock T47 D cells are maintained in growth medium. For BrdU incorporation assay, cells are plated in 96-well plates (Falcon, Becton Dickinson Labware) at 10,000 cells/well in growth medium. After overnight incubation, the medium is changed to treatment medium and cells are cultured for an additional 24 hr before treatment. Stock compounds are dissolved in appropriate vehicle (100% ethanol or 50% ethanol/50% DMSO), subsequently diluted in treatment medium and added to the cells. Progestin and antiprogestin reference compounds are run in full dose-response curves. The final concentration of vehicle is 0.1%. In control wells, cells receive vehicle only. Antiprogestins are tested in the presence of 0.03 nM trimegestone, the reference progestin agonist. Twenty-four hours after treatment, the medium is discarded and cells are labeled with 10 mM BrdU (Amersham Life Science, Arlington Heights, Ill.) in treatment medium for 4 hr.

C. Cell Proliferation Assay:

At the end of BrdU labeling, the medium is removed and BrdU incorporation is measured using a cell proliferation ELISA kit (#RPN 250, Amersham Life Science) according to manufacturer's instructions. Briefly, cells are fixed in an ethanol containing fixative for 30 min, followed by incubation in a blocking buffer for 30 min to reduce background. Peroxidase-labeled anti-BrdU antibody is added to the wells and incubated for 60 min. The cells are rinsed three times with PBS and incubated with 3,3′5,5′-tetramethylbenzidine (TMB) substrate for 10-20 min depending upon the potency of tested compounds. Then 25 μl of 1 M sulfuric acid is added to each well to stop color reaction and optical density is read in a plate reader at 450 nm within 5 min.

Analysis of Results:

Square root-transformed data are used for analysis of variance and nonlinear dose response curve fitting for both agonist and antagonist modes. Huber weighting is used to downweight the effects of outliers. EC₅₀or IC₅₀values are calculated from the retransformed values. JMP software (SAS Institute, Inc.) is used for both one-way analysis of variance and non-linear dose response analyses in both single dose and dose response studies.

Reference Compounds:

Trimegestone and medroxyprogesterone acetate (MPA) were reference progestins and RU486 is the reference antiprogestin. All reference compounds were run in full dose-response curves and the EC₅₀or IC₅₀values were calculated.

(2) Rat Decidualization Assay

Objective:

This procedure was used to evaluate the effect of progestins and antiprogestins on rat uterine decidualization and compare the relative potencies of various test compounds.

Methods:

A. Reagents

Test compounds were dissolved in 100% ethanol and mixed with corn oil (vehicle). Stock solutions of the test compounds in oil (Mazola™) were then prepared by heating (˜80° C.) the mixture to evaporate ethanol. Test compounds were subsequently diluted with 100% corn oil or 10% ethanol in corn oil prior to the treatment of animals. No difference in decidual response was found when these two vehicles were compared.

B. Animals (RACUC Protocol #5002)

Ovariectomized mature female Sprague-Dawley rats (˜60-day old and 230 g) were obtained from Taconic (Taconic Farms, N.Y.) following surgery. Ovariectomy was performed at least 10 days prior to treatment to reduce circulating sex steroids. Animals were housed under 12 hr light/dark cycle and given standard rat chow and water ad libitum

C. Treatment

Rats were weighed and randomly assigned to groups of 4 or 5 before treatment. Test compounds in 0.2 mL vehicle were administered by subcutaneous injection in the nape of the neck or by gavage using 0.5 ml. The animals were treated once daily for seven days. For testing antiprogestins, animals were given the test compounds and a EC50 dose of progesterone (5.6 mg/kg) during the first three days of treatment. Following decidual stimulation, animals continued to receive progesterone until necropsy four days later.

D. Dosing

Doses were prepared based upon mg/kg mean group body weight. In all studies, a control group receiving vehicle was included. Determination of dose-response curves was carried out using doses with half log increases (e.g. 0.1, 0.3, 1.0, 3.0 mg/kg . . . ).

E. Decidual Induction

Approximately 24 hr after the third injection, decidualization was induced in one of the uterine horns by scratching the antimesometrial luminal epithelium with a blunt 21 G needle. The contralateral horn was not scratched and served as an unstimulated control. Approximately 24 hr following the final treatment, rats were sacrificed by CO₂asphyxiation and body weight measured. Uteri were removed and trimmed of fat. Decidualized (D-horn) and control (C-horn) uterine horns were weighed separately.

Analysis of Results:

The increase in weight of the decidualized uterine horn was calculated by D-horn/C-horn and logarithmic transformation was used to maximize normality and homogeneity of variance. The Huber M-estimator was used to down weight the outlying transformed observations for both dose-response curve fitting and one-way analysis of variance. JMP software (SAS Institute, Inc.) was used for both one-way ANOVA and non-linear dose-response analyses.

Reference Compounds:

All progestin reference compounds were run in full dose-response curves and the EC₅₀for uterine wet weight was calculated.

Objective:

To determine a compound's progestational or antiprogestational potency based on its effect on PRE-luciferase reporter activity in CV-1 cells co-transfected with human PR and PRE-luciferase plasmids.

Methods:

A. Reagents:

Culture Medium:

Growth medium: DMEM (BioWhittaker) containing 10% (v/v) fetal bovine serum (heat inactivated), 0.1 mM MEM non-essential amino acids, 1 OOU/ml penicillin, 100 mg/ml streptomycin, and 2 mM GlutaMax (GIBCO, BRL).
Experimental medium: DMEM (BioWhittaker), phenol red-free, containing 10% (v/v) charcoal-stripped fetal bovine serum (heat-inactivated), 0.1 mM MEM non-essential amino acids, 100 U/ml penicillin, 100 mg/ml streptomycin, and 2 mM GlutaMax (GIBCO, BRL).

Cell Culture, Transfection, Treatment, and Luciferase Assay

Stock CV-1 cells were maintained in growth medium. Co-transfection was done using 1.2×10⁷cells, 5 mg pLEM plasmid with hPR-B inserted at Sph1 and BamH1 sites, 10 mg pGL3 plasmid with two PREs upstream of the luciferase sequence, and 50 mg sonicated calf thymus DNA as carrier DNA in 250 ml. Electroporation was carried out at 260 V and 1,000 mF in a Biorad Gene Pulser II. After electroporation, cells were resuspended in growth medium and plated in 96-well plate at 40,000 cells/well in 200 μl. Following overnight incubation, the medium was changed to experimental medium. Cells were then treated with reference or test compounds in experimental medium. Compounds were tested for antiprogestational activity in the presence of 3 nM progesterone. Twenty-four hr. after treatment, the medium was discarded, cells were washed three times with D-PBS (GIBCO, BRL). Fifty ml of cell lysis buffer (Promega, Madison, Wis.) was added to each well and the plates were shaken for 15 min in a Titer Plate Shaker (Lab Line Instrument, Inc.). Luciferase activity was measured using luciferase reagents from Promega.

Analysis of Results:

Each treatment consists of at least 4 replicates. Log transformed data were used for analysis of variance and nonlinear dose response curve fitting for both agonist and antagonist modes. Huber weighting was used to downweight the effects of outliers. EC₅₀or IC₅₀values were calculated from the retransformed values. JMP software (SAS Institute, Inc.) was used for both one-way analysis of variance and non-linear response analyses.

Reference Compounds:

Progesterone and trimegestone were reference progestins and RU486 was the reference antiprogestin. All reference compounds were run in full dose-response curves and the EC₅₀or IC₅₀values were calculated.

(4) T47D Cell Alkaline Phosphatase Assay

Purpose:

To identify progestins or antiprogestins by determining a compound's effect on alkaline phosphatase activity in T47D cells.

Methods:

A. Reagents:

Culture Medium:

DMEM:F12 (1:1) (GIBCO, BRL) supplemented with 5% (v/v) charcoal stripped fetal bovine serum (not heat-inactivated), 1 OOU/ml penicillin, 100 mg/ml streptomycin, and 2 mM GlutaMax (GIBCO, BRL).

Alkaline Phosphatase Assay Buffer:

I. 0.1 M Tris-HCl, pH 9.8, containing 0.2% Triton X-100
II. 0.1 M Tris-HCl, pH 9.8 containing 4 mM p-nitrophenyl phosphate (Sigma).

B. Cell Culture and Treatment:

Frozen T47D cells were thawed in a 37° C. water bath and diluted to 280,000 cells/ml in culture medium. To each well in a 96-well plate (Falcon, Becton Dickinson Labware), 180 μl of diluted cell suspension was added. Twenty μl of reference or test compounds diluted in the culture medium was then added to each well. When testing for progestin antagonist activity, reference antiprogestins or test compounds were added in the presence of 1 nM progesterone. The cells were incubated at 37° C. in a 5% CO₂/humidified atmosphere for 24 hr.
Note: For high throughput screening, one concentration of each compound was tested at 0.3 mg/ml. Based on an average molecular weight of 300 g/mol for the compounds in the library, the concentration was approximately 1 mM. Subsequently, active compounds were tested in dose response assays to determine EC₅₀or IC₅₀

C. Alkaline Phosphatase Enzyme Assay:

At the end of treatment, the medium was removed from the plate. Fifty μl of assay buffer I was added to each well. The plates were shaken in a titer plate shaker for 15 min. Then 150 μl of assay buffer II was added to each well. Optical density measurements were taken at 5 min intervals for 30 min at a test wavelength of 405 nM.

Analysis of Results:

Analysis of Dose-Response Data

For reference and test compounds, a dose response curve was generated for dose (X-axis) vs. the rate of enzyme reaction (slope) (Y-axis). Square root-transformed data were used for analysis of variance and nonlinear dose response curve fitting for both agonist and antagonist modes. Huber weighting was used to downweight the effects of outliers. EC₅₀or IC₅₀values were calculated from the retransformed values. JMP software (SAS Institute, Inc.) was used for both one-way analysis of variance and non-linear dose response analyses in both single dose and dose response studies.

Reference Compounds:

Progesterone and trimegestone were reference progestins and RU486 was the reference antiprogestin. All reference compounds were run in full dose response curves and the EC₅₀or IC₅₀values were calculated.

The compounds of the present invention can be used in the form of salts derived from pharmaceutically or physiologically acceptable acids or bases. These salts include, but are not limited to, the following salts with inorganic acids such as hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid and, as the case may be, such organic acids as acetic acid, oxalic acid, succinic acid, and maleic acid. Other salts include salts with alkali metals or alkaline earth metals, such as sodium, potassium, calcium or magnesium in the form of esters, carbamates and other conventional “pro-drug” forms, which, when administered in such form, convert to the active moiety in vivo.
When the compounds are employed for the above utilities, they may be combined with one or more pharmaceutically acceptable carriers, for example, solvents, dilutents and the like, and may be administered orally in such forms as tablets, capsules, dispersible powders, granules, or suspensions containing, for example, from about 0.05 to 5% of suspending agent, syrups containing, for example, from about 10 to 50% of sugar, and elixirs containing, for example, from about 20 to 50% ethanol, and the like, or parenterally in the form of sterile injectable solutions or suspensions containing from about 0.05 to 5% suspending agent in an isotonic medium. Such pharmaceutical preparations may contain, for example, from about 25 to about 90% of the active ingredient in combination with the carrier, more usually between about 5% and 60% by weight.
The effective dosage of active ingredient employed may vary depending on the particular compound employed, the mode of administration and the severity of the condition being treated. However, in general, satisfactory results are obtained when the compounds of the invention are administered at a daily dosage of from about 0.5 to about 500 mg/kg of animal body weight, preferably given in divided doses two to four times a day, or in a sustained release form. For most large mammals, the total daily dosage is from about 1 to 100 mg, preferably from about 2 to 80 mg. Dosage forms suitable for internal use comprise from about 0.5 to 500 mg of the active compound in intimate admixture with a solid or liquid pharmaceutically acceptable carrier. This dosage regimen may be adjusted to provide the optimal therapeutic response. For example, several divided doses may be administered daily or the dose may be proportionally reduced as indicated by the exigencies of the therapeutic situation.
These active compounds may be administered orally as well as by intravenous, intramuscular, or subcutaneous routes. Solid carriers include starch, lactose, dicalcium phosphate, microcrystalline cellulose, sucrose and kaolin, while liquid carriers include sterile water, polyethylene glycols, non-ionic surfactants and edible oils such as corn, peanut and sesame oils, as are appropriate to the nature of the active ingredient and the particular form of administration desired. Adjuvents customarily employed in the preparation of pharmaceutical compositions may be advantageously included, such as flavoring agents, coloring agents, preserving agents, and antioxidants, for example, vitamin E, ascorbic acid, BHT and BHA.
The preferred pharmaceutical compositions from the standpoint of ease of preparation and administration are solid compositions, particularly tablets and hard-filled or liquid-filled capsules. Oral administration of the compounds is preferred.
These active compounds may also be administered parenterally or intraperitoneally. Solutions or suspensions of these active compounds as a free base or pharmacologically acceptable salt can be prepared in water suitably mixed with a surfactant such as hydroxypropylcellulose. Dispersions can also be prepared in glycerol, liquid, polyethylene glycols and mixtures thereof in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.
The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form must be sterile and must be fluid to the extent that easy syringe ability exits. It must be stable under conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacterial and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol (e.g., glycerol, propylene glycol and liquid polyethylene glycol), suitable mixtures thereof, and vegetable oil.
All patents, publications, and other documents cited herein are hereby incorporated by reference in their entirety.
