Description

[0002] The present invention relates to new 2-Phenyl-1-[4-(2-Aminoethoxy)-Benzyl]-Indole compounds which are useful as estrogenic agents, as well as pharmaceutical compositions and methods of treatment utilizing these compounds.

BACKGROUND OF THE INVENTION

[0003] The use of hormone replacement therapy for bone loss prevention in post-menopausal women is well precedented. The normal protocol calls for estrogen supplementation using such formulations containing estrone, estriol, ethynyl estradiol or conjugated estrogens isolated from natural sources (i.e. Premarin® conjugated estrogens from Wyeth-Ayerst). In some patients, therapy may be contraindicated due to the proliferative effects of unopposed estrogens (estrogens not given in combination with progestins) have on uterine tissue. This proliferation is associated with increased risk for endometriosis and/or endometrial cancer. The effects of unopposed estrogens on breast tissue is less clear, but is of some concern. The need for estrogens which can maintain the bone sparing effect while minimizing the proliferative effects in the uterus and breast is evident. Certain nonsteroidal antiestrogens have been shown to maintain bone mass in the ovariectomized rat model as well as in human clinical trials. Tamoxifen (sold as Novadex® brand tamoxifen citrate by Zeneca Pharmaceuticals, Wilmington, Del.), for example, is a useful palliative for the treatment of breast cancer and has been demonstrated to exert an estrogen agonist-like effect on the bone, in humans. However, it is also a partial agonist in the uterus and this is cause for some concern. Raloxifene, a benzothiophene antiestrogen, has been shown to stimulate uterine growth in the ovariectomized rat to a lesser extent than Tamoxifen while maintaining the ability to spare bone. A suitable review of tissue selective estrogens is seen in the article “Tissue-Selective Actions Of Estrogen Analogs”, Bone Vol. 17, No. 4, October 1995, 181S-190S.

[0004] The use of indoles as estrogen antagonists has been reported by Von Angerer, Chemical Abstracts, Vol. 99, No. 7 (1983), Abstract No. 53886u. Also, see, J.Med.Chem. 1990, 33, 2635-2640; J.Med.Chem. 1987, 30, 131-136. Also see Ger. Offen., DE 3821148 A1 891228 and WO 96/03375. These prior art compounds share some structural similarities with the present compounds, but are functionally different. For compounds containing a basic amine, there is no phenyl group to ridgidify the side chain. The reported data for these compounds indicates that they may have a weaker binding to estrogen receptor than the compounds of the present invention and the reported compounds containing the basic side chain show some uterotrophic effect in the rat uterus. One compound from the listed family of compounds in WO 96/03375 possesses a benzyl group, but does not have a basic side chain. The majority of these compounds fall into a class of compounds best characterized as being “pure antiestrogens”. Many of the compounds described presently, due to their particular side chain, act as pure antiestrogens in the uterus, however, show strong estrogenic action in the bone and cardiovascular systems. No such action is demonstrated for the related prior art compounds described herein.

[0005] WO A 95 17383 (Kar Bio AB) describes indole antiestrogens with long straight chains. Another related patent WO A 93 10741 describes 5-Hydroxyindole with a generic descriptor incorporating other side chains. WO 93/23374 (Otsuka Pharmaceuticals, Japan) describes compounds which differ from the present invention; where R3 in the present formulas I and II, below, is defined as thioalkyl and the reference discloses no such compounds having chains from the indole nitrogen having the same structure as the ones provided by the present invention. Where the side chain claimed is similar to that described herein, the compounds are amides: Acylated indoles are not claimed in the present invention.

DESCRIPTION OF THE INVENTION

[0006] 2-Phenylindoles of the general structure type shown in formulas (I) and (II) are estrogen agonists/antagonists useful for the treatment of diseases associated with estrogen deficiency. The compounds of the present invention show strong binding to the estrogen receptor. In vitro assays, including an Ishikawa alkaline phoshatase assay and an ERE transfection assay, show these compounds are antiestrogens with little to no intrinsic estrogenicity and they have proven capable of completely antagonizng the effects of 17β-estradiol while showing little or no uterine stimulation in a rat uterine assay when dosed alone. Additionally, some of these compounds are capable of inhibiting bone loss in an ovariectomized rat while showing little or no uterine stimulation. These compounds also decrease the weight gain normally seen in the ovariectomized animals as well as reduce total cholesterol levels.

[0033] The invention includes sulfate, sulfates and sulfate esters of phenolic groups. Sulfates can be readily prepared by the reaction of the free phenolic compounds with sulfur trioxide complexed with an amine such as pyridine, trimethylamine, triethylamine, etc. Sulfamates can be prepared by treating the free phenolic compound with the desired amino or alkylamino or dialkylamino sulfamyl chloride in the presence of a suitable base such as pyridine. Sulfate esters can be prepared by reaction of the free phenol with the desired alkanesulfonyl chloride in the presence of a suitable base such as pyridine. Additionally, this invention includes compounds containing phosphates at the phenol as well as dialkyl phoshates. Phosphates can be prepared by reaction of the phenol with the appropriate chlorophosphate. The dialkyiphosphates can be hydrolyzed to yield the free phosphates. Phosphinates are also claimed where the phenol is reacted with the desired dialkylphosphinic chloride to yield the desired dialkylphosphinate of the phenol.

[0034] The invention includes acceptable salt forms formed from the addition reaction with either inorganic or organic acids. Inorganic acids such as hydrochloric acid, hydrobromic acid, hydroiodic acid, sufuric acid, phoshoric acid, nitric acid useful as well as organic acids such as acetic acid,propionic acid, citric acid, maleic acid, malic acid, tartaric acid, phthalic acid, succinic acid, methanesulfonic acid, toluenesulfonic acid, napthalenesulfonic acid, camphorsulfonic acid, benzenesulfonic acid are useful. It is known that compounds possessing a basic nitrogen can be complexed with many different acids (both protic and non-protic) and usually it is preferred to administer a compound of this invention in the form of an acid addition salt. Additionally, this invention includes quaternary ammonium salts of the compounds herein. These can be prepared by reacting the nucleophilic amines of the side chain with a suitably reactive alkylating agent such as an alkyl halide or benzyl halide.

Methods

[0035] Compounds of this invention can be synthesized in a general sense according to Scheme 1, below. 6

[0036] The initial indole synthesis is accomplished by heating an appropriately substituted alpha-bromo ketone (b) with the desired aniline (a) in DMF to form the indole (c). The product is then alkylated with a benzyl chloride (e) to give the substituted indole (f). The benzyl chloride (e) can be readily prepared from the aldehyde (d) in 2 steps as given. Product (g) can be prepared from (f) by reduction of the ester, conversion of the alcohol to a bromide, displacement of the bromide with the desired amine in a suitable solvent such as THF or DMF, and finally, deprotected if necessary. Deprotection is necessary when either R1 or R2 or both is a protected phenol. The preferred protecting group is a benzyl group which can be conveniently removed by several conventional methods, especially hydrogenolysis.

[0037] For the synthesis of compounds with X═H, halogen, trifluoromethyl, cyano, nitro, an alternative synthesis shown in scheme 2 may be preferable. The formation of halogens at the 3-position can be easily performed with such reagents as N-chlorosuccinamide, N-bromosuccinamide, or N-iodosuccinamide. A 3-Iodoindole compound obtained can be used as a precursor to the 3-trifluoromethyl compound by a coupling reaction utilizing a palladium catalyst and bistrifluoromethyl mercury (II). A compound with a cyano group in the 3-position can be prepared by electrophilic cyanation or alternatively the 3-position can be formylated (with a formyl iminium salt, for example) then the formyl group converted to an oxime and subsequently dehydrated to a nitrile. Alternatively, the 3-cyano compound can be synthesized by reaction of the 3-unsubstituted indole with chlorosulfonylisocyanate followed by triethylamine. A compound with the nitro group in the 3-position can be prepared by treating the indole with sodium nitrite and acetic acid. One skilled in the art recognizes these routes are not limiting and other routes are also available. 7

[0038] Synthesis of selected representative examples are given in the following schemes: 8

[0039] The synthesis of analogues with a 3-carbon chain (example No. 166) between the oxygen and the basic amine can be accomplished as shown in scheme 4. 9

[0040] The synthetic procedure shown in scheme 4 may be used for compounds with two carbon chains analogous to example No. 97 in scheme 3. This is shown in scheme 4a for the synthesis of example No. 127. 10

[0041] The synthesis of indoles with alternative substituents (CN, Cl) at the 3-position of the indole both utilize the 3-unsubstituted indole No. 141 for a precursor. The indole is synthesized by the Fisher method utilizing the hydrazone derived from the condensation of 4-benzyloxyacetophenone CAS No. [54696-05-8] and 4-benzyloxyphenylhydrazine CAS No. [51145-58-5]. The hydrazone No. 140 is then cyclized in acetic acid using zinc chloride to afford the desired indole No. 141. This synthesis can be seen in scheme 5. 11

[0042] The synthesis of 3-Chloroindole compounds is demonstrated for example No. 134 and shown, infra, in scheme 6. The indole No. 141 from scheme 5 is chlorinated with N-chlorosuccinamide. The 3-Chloroindole No. 142, thus obtained, is taken to the final product in analogous fashion to that shown in scheme 3. 12

[0043] 3-Cyano analogues are synthesized from the precursor indole No. 141 as shown in Scheme 7. Reaction of the precursor indole No. 141 with chlorosulfonyl isocyanate followed by addition of triethylamine yields the 3-Cyanoindole No. 155. The side chain is made by conversion of the benzylic alcohol of CAS No. [111728-87-1] to the benzylic bromide No. 156 using thionyl bromide in THF. The indole is alkylated by the side chain in DMF using sodium hydride to give the intermediate No. 157. This can then be taken to the final product No. 138 in an analogous fashion to that shown in scheme 4. 13

[0044] The compounds of the invention are selective estrogen agonists and display high affinity for the estrogen receptor. Unlike many estrogens, however, many of these compounds do not cause increases in uterine wet weight. These Compounds are antiestrogenic in the uterus and can completely antagonize the trophic effects of estrogen agonists in uterine tissue. Due to the tissue selective nature of these compounds, they are useful in treating or preventing in a mammal disease states or syndromes which are caused or associated with an estrogen deficiency (in certain tissues such as bone or cardiovascular) or an excess of estrogen (in the uterus or mammary glands). They may also be used in methods of treatment for diseases or disorders which result from proliferation or abnormal development, actions or growth of endometrial or endometrial-like tissues.

[0045] The present compounds have the ability to behave like estrogen agonists by lowering cholesterol and preventing bone loss. These compounds are useful for treating many maladies which result from estrogen effects and estrogen excess or deficiency including osteoporosis, prostatic hypertrophy, male pattern baldness, vaginal and skin atrophy, acne, dysfunctional uterine bleeding, endometrial polyps, benign breast disease, uterine leiomyomas, adenomyosis, ovarian cancer, infertility, breast cancer, endometriosis, endometrial cancer, polycystic ovary syndrome, cardiovascular disease, contraception, Alzheimer's disease, cognitive decline and other CNS disorders, as well as certain cancers including melanoma, prostrate cancer, cancers of the colon, CNS cancers, among others. Additionally, these compounds can be used for contraception in pre-menopausal women, as well as hormone replacement therapy in post-menopausal women or in other estrogen deficiency states where estrogen supplementation would be beneficial. They may also be used in disease states where amenorrhea is advantageous, such as leukemia, endometrial ablations, chronic renal or hepatic disease or coagulation diseases or disorders.

[0046] The compounds of this invention may also be used in methods of treatment for and prevention of bone loss, which may result from an imbalance in a individual's formation of new bone tissues and the resorption of older tissues, leading to a net loss of bone. Such bone depletion results in a range of individuals, particularly in post-menopausal women, women who have undergone bilateral oophorectomy, those receiving or who have received extended corticosteroid therapies, those experiencing gonadal dysgenesis, and those suffering from Cushing's syndrome. Special needs for bone, including teeth and oral bone, replacement can also be addressed using these compounds in individuals with bone fractures, defective bone structures, and those rceiving bone-related surgeries and/or the implantation of prosthesis. In addition to those problems described above, these compounds can be used in treatments for osteoarthritis, hypocalcemia, hypercalcemia, Paget's disease, osteomalacia, osteohalisteresis, multiple myeloma and other forms of cancer having deleterious effects on bone tissues Methods of treating the maladies listed herein are understood to comprise administering to an individual in need of such treatment a pharmaceutically effective amount of one or more of the compounds of this invention or a pharmacetically acceptable salt thereof. This invention also includes pharmaceutically compositions utilizing one or more of the present compounds, and/or the pharmaceutically acceptable salts thereof, along with one or more pharmaceutically acceptable carriers, excipients, etc.

[0047] It is understood that the dosage, regimen and mode of administration of these compounds will vary according to the malady and the individual being treated and will be subject to the judgement of the medical practitioner involved. It is preferred that the administration of one or more of the compounds herein begin at a low dose and be increased until the desired effects are achieved.

[0048] Effective administration of these compounds may be given at a dose of from about 0.1 mg/day to about 1,000 mg/day. Preferably, administration will be from about 10 mg/day to about 600 mayday, more preferably from about 50 mg/day to about 600 mg/day, in a single dose or in two or more divided doses. Such doses may be administered in any manner useful in directing the active compounds herein to the recipient's bloodstream, including orally, via implants, parenterally (including intravenous, intraperitoneal and subcutaneous injections), rectally, vaginally, and transdermally. For the purposes of this disclosure, transdermal administrations are understood to include all administrations across the surface of the body and the inner linings of bodily passages including epithelial and mucosal tissues. Such administrations may be carried out using the present compounds, or pharmaceutically acceptable salts thereof, in lotions, creams, foams, patches, suspensions, solutions, and suppositories (rectal and vaginal).

[0049] Oral formulations containing the active compounds of this invention may comprise any conventionally used oral forms, including tablets, capsules, buccal forms, troches, lozenges and oral liquids, suspensions or solutions. Capsules may contain mixtures of the active compound(s) with inert fillers and/or diluents such as the pharmaceutically acceptable starches (e.g. corn, potato or tapioca starch), sugars, artificial sweetening agents, powdered celluloses, such as crystalline and microcrystalline celluloses, flours, gelatins, gums, etc. Useful tablet formulations may be made by conventional compression, wet granulation or dry granulation methods and utilize pharmaceutically acceptable diluents, binding agents, lubricants, disintegrants, suspending or stabilizing agents, including, but not limited to, magnesium stearate, stearic acid, talc, sodium lauryl sulfate, microcrystalline cellulose, carboxymethylcellulose calcium, polyvinylpyrrolidone, gelatin, alginic acid, acacia gum, xanthan gum, sodium citrate, complex silicates, calcium carbonate, glycine, dextrin, sucrose, sorbitol, dicalcium phosphate, calcium sulfate, lactose, kaolin, mannitol, sodium chloride, talc, dry starches and powdered sugar. Oral formulations herein may utilize standard delay or time release formulations to alter the absorption of the active compound(s). Suppository formulations may be made from traditional materials, including cocoa butter, with or without the addition of waxes to alter the suppository's melting point, and glycerin. Water soluble suppository bases, such as polyethylene glycols of various molecular weights, may also be used.

[0050] Aldrich Sure Seal™ Solvents, anhydrous without further purification, may be used for the reactions described herein and may be obtained from Aldrich Chemical Company. All reactions were carried out under a nitrogen atmosphere. Chromatography was performed using 230-400 mesh silica gel (Merck Grade 60, Aldrich Chemical Company). Thin layer chromatography was performed with Silica Gel 60 F254 plates from EM Science. 1H NMR spectra were obtained on a Bruker AM-400 or Bruker DPX-300 instrument in DMSO and chemical shifts reported in ppm. Melting points were determined on a Thomas-Hoover apparatus and are uncorrected. IR spectra were recorded on a Perkin-Elmer diffraction grating or Perkin-Elmer 784 spectrophotometers. Mass spectra were recorded on a Kratos MS 50 or Finnigan 8230 mass spectrometers. Elemental analyses were obtained with a Perkin-Elmer 2400 elemental analyzer. Compounds for which CHN are reported are within 0.4% of the theoretical value for the formula given unless expressed otherwise. Compound nomenclature was generally arrived at by use of the Beilstein Autonom™ program.

Synthesis of α-bromo Ketones

Method a

[0051] The synthesis of the alpha bromo ketones is conveniantly accomplished by simply dissolving the starting phenyl ketone in ethyl ether (0.05-0.10 M) and at room temperature, 1.1 equivalents of bromine is added in dropwise. The reaction can be monitored by TLC for consumption of starting materials. The reaction is worked up by washing with an aqueous sodium bicarbonate solution followed by a 10% aqueous sodium sulfite solution. The ether layer is washed with brine and dried over magnesium sulfate. Concentration of the reaction mixture typically yields the bromoketones in good yield and purity. The bromoketones were taken “as is” (without purification or characterization) to the next step.

ILLUSTRATED FOR EXAMPLE NO. 7

5-Benzyloxy-2-(4-benzyloxy-phenyl)-3-methyl-1H-indole

[0053] A flask was charged with 4-benzyloxyaniline hydrochloride CAS No. [51145-58-5]. (45 g, 0.23 mol), 4′-benzyloxy-2-bromophenylpropiophenone CAS No. [66414-19-5] (21 g, 0.066 mol), and 50 mL DMF. The reaction was heated at reflux for 30 minutes and then cooled to rt and then partitioned between 250 mL EtOAc and 100 mL 1N HCl (aq). The EtOAc was washed with NaHCO3 (aq) and brine, then dried over MgSO4. The solution was concentrated and the residue taken up in CH2Cl2 and hexanes added to precipitate out 25 g of a crude solid. The solid was dissolved in CH2Cl2 and evaporated onto silica gel and chromatographed using CH2Cl2/Hexane (1:5) to yield 9.2 g of a tan solid (33%): Mp=150-152° C.; 1H NMR (DMSO) 10.88 (s, 1H), 7.56 (d, 2H, J=8.8 Hz), 7.48 (d, 4H, J=7.9 Hz), 7.42-7.29 (m, 6H), 7.21 (d, 1H, J=7.0 Hz), 7.13 (d, 2H, J=8.8 Hz), 7.08 (d, 1H, J=2.2 Hz), 6.94 (dd, 1H, J=8.8, 2.4 Hz), 5.16 (s, 2H), 5.11 (s, 2H), 2.33 (s, 3H); IR (KBr) 3470, 2880, 2820, 1620 cm−1; MS eI m/z 419.

Method 2 (Shown in Scheme 8)

ALSO ILLUSTRATED FOR EXAMPLE NO. 7

[0054] Reagents used were same as in method 1 except the additional use of triethylamine in this method. The bromoketone CAS No. [66414-19-5] (50.0 g, 0.16 mol) in 200 mL DMF was treated with the aniline hydrochloride CAS No. [51145-58-5] (44 g, 0.22 mol) and the reaction purged with nitrogen for about 10 minutes. The triethylamine (54.6 mL) was added and the reaction was heated at 120° C. for 2 hours. TLC analysis (EtOAc/hexanes) shows the starving material has dissappeared forming a more polar spot The reaction mixture is allowed to cool down and an additional 48 g of the aniline hydrochloride was added. The reaction was heated to 150° C. for 2 hours. An additional 5 grams of the aniline hydrochloride was added and the reaction was heated at 150° C. for an additional 30 minutes. The reaction mixture is allowed to cool to room temperature and then poured into approximately 1.5 liters of water and extracted with 2 liters of ethyl acetate. Solids are dissolved with additional ethyl acetate as neccessary. The ethyl acetate layer is washed with 1 liter of 1 N NaOH solution aq., 1 liter of water, brine, then dried over magnesium sulfate and filtered The organic layers were concentrated down to yield a crude solid which is stirred with 500 mL of methanol and filtered This solid is then stirred with 500 mL of ethyl ether and filtered. The solid is stirred alternatively with methanol and ether until it is of whitish color and has a melting point similar to that described for No. 7 in method 1. Reaction yields 36 grams of product.

Hydrogenation of Indoles Containing Benzyl Ether(s)

Method 7

ILLUSTRATED FOR EXAMPLE NO. 97

2-(4-Hydroxy-phenyl)-3-methyl-1-[4-(2-piperidin-1-yl-ethoxy)-benzyl]-1H-indol-5-ol

[0160] A suspension of 10% Pd/C (1.1 g) in EtOH was treated with a solution of No. 63 (2.2 g, 3.4 mmol) in THF EtOH. Cyclohexadiene (6.0 mL, 63 mmol) was added and the reaction was stirred for 48 hours. The catalyst was filtered through Celite and the reaction mixture was concentrated and chromatographed on silica gel using a gradient elution of MeOH/CH2Cl2 (1:19 to 1:10) to yield 0.8 g of the product as a white solid. Mp=109-113° C.; CHN calc'd for C29H32N2O3+0.5 H2O; 1H NMR 9.64 (s, 1H, 8.67 (s, 1H), 7.14 (d, 2H, J=8.6 Hz), 7.05 (d, 1H, J=8.6 Hz), 6.84 (d, 2H, J=8.8 Hz), 6.79 (d, 1H, J=2.2 Hz), 6.74 (s, 4H), 6.56 (dd, 1H, J=8.8, 2.4 Hz), 5.09 (s, 2H), 3.95-3.93 (m, 2H), 2.60-2.51 (m, 2H), 2.39-2.38 (m, 4H), 2.09 (s, 3H), 1.46-1.45 (m, 4H), 1.35-1.34 (m, 2H); IR (KBr) 3350 (br), 2920, 1620, 1510 cm−1; MS (EI) m/z 456.

[0161] Alternatively, the compounds may be dissolved in a THF/EtOH solution (or other appropriate solvent) and hydrogenated with H2 and 10% Pd/C using either a ballon or Parr Hydrogenator. Either procedure is effective. In many of the examples, the compounds were made into acid addition salts. The procedure for the preparation of an HCl salt is given below (Method 8).

Method 8

[0162] 1.0 g of Example No. 97 free base from the hydrogenation procedure above in a large test tube was dissolved in 20 mL of MeOH. This was treated with slow addition of 2.6 mL 1.0 N HCl and then 4.0 mL deionized water. The tube was partially opened to the atmosphere to encourage slow evaporation of the solvents. After about ten minutes, crystals began to appear and after 4 hours the solution was filtered and the solid crystals washed with water. The product was present as 0.42 g of white crystalline plates with a melting point of 184-185° C. The mother liquor yielded an additional crop of 0.30 g of white solid with a melting point of 177-182° C. CHN calc'd for C29H32N2O3+HCL+1H2O.

[0163] Alternatively, the compounds can be made into quaternary ammonium salts. An example procedure for the synthesis of example No. 107 is given below (Method 9).

2-(4-Hydroxy-phenyl)-3-methyl-1-[4-(2-piperidin-1-yl-ethoxy)-benzyl]-1H-indol-5-ol methiodide

[0164] 0.8 g of example No.97 was dissolved in 18 mL THF and treated with 2 mL of methyl iodide. The solution was heated to reflux for an hour. The reaction was allowed to come to room temperature and the solids filtered to yield 0.72 g as a crystalline solid.

[0287] Biological Data

Method 16

In vitro Estrogen Receptor Binding Assay

Receptor Preparation

[0288] CHO cells overexpressing the estrogen receptor were grown in 150 mm2 dishes in DMEM+10% dextran coated charcoal, stripped fetal bovine serum. The plates were washed twice with PBS and once with 10 mM Tris-HCl, pH 7.4, 1 mM EDTA. Cells were harvested by scraping the surface and then the cell suspension was placed on ice. Cells were disrupted with a hand-held motorized tissue grinder using two, 10-second bursts. The crude preparation was centrifuged at 12,000 g for 20 minutes followed by a 60 minute spin at 100,000 g to produce a ribosome free cytosol. The cytosol was then frozen and stored at −80° C. Protein concentration of the cytosol was estimated using the BCA assay with reference standard protein.

Binding Assay Conditions

[0289] The competition assay was performed in a 96-well plate (polystyrene*) which binds <2.0% of the totals input [3H]-17β-estradiol and each data point was gathered in triplicate. 100 uG/100 uL of the receptor preparation was aliquoted per well. A saturating dose of 2.5 nM [3H]17β-estradiol+competitor (or buffer) in a 50 uL volume was added in the preliminary competition when 100× and 500× competitor were evaluated, only 0.8 nM [3H]17β-estradiol was used. The plate was incubated at room temperature for 2.5 h. At the end of this incubation period 150 uL of ice-cold dextran coated charcoal (5% activated charcoal coated with 0.05% 69K dextran) was added to each well and the plate was immediately centrifuged at 99 g for 5 minutes at 4° C. 200 uL of the supernatant solution was then removed for scintillation counting. Samples were counted to 2% or 10 minutes, whichever occurs first. Because polystyrene absorbs a small amount of [3H]17β-estradiol wells containing radioactivity and cytosol, but not processed with charcoal were included to quantitate amounts of available isotope. Also, wells containing radioactivity but no cytosol were processed with charcoal to estimate unremovable DPM of [3H]17β-estradiol Corning No. 25880-96, 96-well plates were used because they have proven to bind the least amount of estradiol.

Analysis of Results

[0290] Counts per minute (CPM) of radioactivity were automatically converted to disintegrated per minute (DPM) by the Beckman LS 7500 Scintillation Counter using a set of quenched standards to generate a H No. for each sample. To calculate the % of estradiol binding in the presence of 100 or fold 500 fold competitor the following formula was applied:

((DPM sample-DPM not removed by charcoal/(DPM estradiol-DPM not removed by charcoal))×100%=% of estradiol binding

[0291] For the generation of IC50 curves, % binding is plotted vs compound. IC50's are generated for compounds that show >30% competition at. 500× competitor concentration.

Ishikawa Cell Alkaline Phosphatase Assay

Cell Maintenance and Treatment:

[0296] Ishikawa cells were maintained in DMEM/F12 (50%:50%) containing phenol red+10% fetal bovine serum and the medium was supplemented with 2 mM Glutamax, 1% Pen/Strap and 1 mM sodium pyruvate. Five days prior to the beginning of each experiment (treatment of cells) the medium was changed to phenol red-free DMEM/F12+10% dextran coated charcoal stripped serum On the day before treatment, cells were harvested using 0.5% trypsin/EDTA and plated at a density of 5×104 cells/well in 96-well tissue culture plates. Test compounds were dosed at 10−6, 10−7 and 10−8M in addition to 10−6 M (compound)+10−9 M 17β-estradiol to evaluate the ability of the compounds to function as antiestrogens. Cells were treated for 48 h prior to assay. Each 96-well plate contained a 17β-estradiol control. Sample population for at each dose was n=8.

Alkaline Phosphatase Assay

[0297] At the end of 48 h the media is aspirated and cells are washed three times with phosphate buffered saline (PBS). 50 μL of lysis buffer (0.1 M Tris-HCl, pH 9.8, 0.2% Triton ×-100) is added to each well. Plates are placed at −80° C. for a minimum of 15 minutes. Plates are thawed at 0.37° C. followed by the addition of 150 μL of 0.1 M Tris-HCl, pH 9.8, containing 4 mM para-nitrophenylphosphate (pNPP) to each well (final concentration, 3 mM pNPP).

[0298] Absorbance and slope calculations were made using the KineticCalc Application program (Bio-Tek Instruments, Inc., Winooski, Vt.). Results are expressed as the mean+/−S.D. of the rate of enzyme reaction (slope) averaged over the linear portion of the kinetic reaction curve (optical density readings every 5 minutes for 30 minutes absorbance reading). Results for compounds are summarized as percent of response related to 1 nM 17β-estradiol.

[0299] Various compounds were assayed for estrogenic activity by the alkaline phosphatase method and corresponding ED50 values (95% C.I.) were calculated The four listed in the following were used as as reference standards:

17β-estradiol 0.03 nM
17α-estradiol 1.42 nM
estriol       0.13 nM
estrone       0.36 nM

[0300] A description of these methods is described by Holinka, C. F., Hata, H., Kuramoto, H. and Gurpide, E. (1986) Effects of steroid hormones and antisteroids on alkaline phosphatase activity in human endometrial cancer cells (Ishikawa Line). Cancer Research, 46:2771-2774, and by Littlefield, B.

2× VIT ERE Infection Assay

Cell Maintenance and Treatment

[0302] Chinese Hamster Ovary cells (CHO) which had been stably transfected with the human estrogen receptor were maintained in DMEM+10% fetal bovine serum (FBS). 48 h prior to treatment the growth medium was replaced with DMEM lacking phenol red +10% dextran coated charcoal stripped FBS (treatment medium). Cells were plated at a density of 5000 cells/well in 96-well plates containing 200 μL of medium/well.

Calcium Phoshate Transfection

[0303] Reporter DNA (Promega plasmid pGL2 containing two tandem copies of the vitellogenin ERE in front of the minimal thymidine kinase promoter driving the luciferase gene) was combined with the B-galactosidase expression plasmid pCH110 (Pharmacia) and carrier DNA (pTZ18U) in the following ratio:

[0304] 10 uG of reporter DNA

[0305] 5 uG of pCH110DNA

[0306] 5 uG of pTZ18U

[0307] 20 uG of DNA/1 mL of transfection solution

[0308] The DNA (2 uG) was dissolved in 500 uL of 250 mM sterile CaCl2 and added dropwise to 500 uL of 2× HeBS (0.28 M NaCl, 50 mM HEPES, 1.5 mM Na2HPO4, pH 7.05) and incubated at room temperature for 20 minutes. 20 uL of this mixture was added to each well of cells and remained on the cells for 16 h. At the end of this incubation the precipitate was removed, the cells were washed with media, fresh treatment media was replaced and the cells were treated with either vehicle, 1 nM 17β-estradiol, 1 uM compound or 1 uM compound+1 nM 17β-estradiol (tests for estrogen antagonism). Each treatment condition was performed on 8 wells (n=8) which were incubated for 24 h prior to the luciferase assay.

Luciferase Assay

[0309] After 24 h exposure to compounds, the media was removed and each well washed with 2× with 125 uL of PBS lacking Mg++ and Ca++. After removing the PBS, 25 uL of Promega lysis buffer was added to each well and allowed to stand at room temperature for 15 min, followed by 15 min at −80° C. and 15 min at 37° C. 20 uL of lysate was transferred to an opaque 96 well plate for luciferase activity evaluation and the remaining lysate (5 uL) was used for the B-galactosidase activity evaluation (normalize transfection). The luciferan substrate (Promega) was added in 100 uL aliquots to each well automatically by the luminometer and the light produced (relative light units) was read 10 seconds after addition.

raloxifene    0% activity (0% with 1 nM 17β-estradiol)

B-Galactosidase Assay

[0311] To the remaining 5 uL of lysate 45 uL of PBS was added. Then 50 uL of Promega B-galactosidase 2× assay butter was added, mixed well and incubated at 37° C. for 1 hour. A plate containing a standard curve (0.1 to 1.5 milliunits in triplicate) was set up for each experimental run. The plates were analyzed on a Molecular Devices spectrophotometric plate reader at 410 nm. The optical densities for the unknown were converted to milliunits of activity by mathematical extrapolation from the standard curve.

Analysis of Results

[0312] The luciferase data was generated as relative light units (RLUs) accumulated during a 10 second measurement and automatically transferred to a JMP (SAS Inc) file where background RLUs were subtracted. The B-galactosidase values were automatically imported into the file and these values were divided into the RLUs to normalize the data. The mean and standard deviations were determined from a n=8 for each treatment Compounds activity was compared to 17β-estradiol for each plate. Percentage of activity as compared to 17β-estradiol was calculated using the formula %=((Estradiol-control)/(compound value)) ×100. These techniques are described by Tzukerman, M. T., Esty, A., Santiso-Mere, D., Danielian, P., Parker, M. G., Stein, R. B., Pike, J. W. and McDonnel, D. P. (1994). Human estrogen receptor taansactivational capacity was determined by both cellular and promoter context and mediated by two functionally distinct intramolecular regions (see Molecular Endocrinology, 8:21-30).

Rat Uterotrophic/Antiuterotrophic Bioassay

[0313] The estrogenic and antiestrogenic properties of the compounds were determined in an immature rat uterotrophic assay (4 day) that (as described previously by L. J. Black and R. L. Goode, Life Sciences, 26, 1453 (1980)). Immature Sprague-Dawley rats (female, 18 days old) were tested in groups of six. The animals were treated by daily ip injection with. 10 uG compound, 100 uG compound, (100 uG compound+1 uG 17β-estradiol) to check antiestrogenicity, and 1 uG 17β-estradiol with 50% DMSO/50% saline as the injection vehicle. On day 4 the animals were sacrificed by CO2 asphyxiation and their uteri were removed and stripped of excess lipid, any fluid removed and the wet weight determined. A small section of one horn was submitted for histology and the remainder used to isolate total RNA in order to evaluate complement component 3 gene expression.

6-Week Ovariectomized Rat Model

[0314] Female Sprague Dawley CD rats, ovx or sham ovx, were obtained 1 day after surgery from Taconic Farm (weight range 240-275 g). They were housed 3 or 4 rats/cage in a room on a 14/10 (light/dark) schedule and provided with food (Purina 500 rat chow) and water ad libitum Treatment for all studies began 1 day after the animals arrival and dosed 5 or 7 days per week as indicated for 6 weeks. A group of age matched sham operated rats not receiving any treatment served as an intact, estrogen replete control group for each study. All treatments were prepared in 1% tween 80 in normal saline at defined concentrations so that the treatment volume was 0.1 mL/100 g body weight 17-beta estradiol was dissolved in corn oil (20 uG/mL) and delivered subcutaneously, 0.1 mL/rat. All dosages were adjusted at three week intervals according to group mean body weight measurements.

[0315] Five weeks after the initiation of treatment and one week prior to the termination of the study, each rat was evaluated for bone mineral density (BMD). The BMD's of the proximal tibiae (PT) and fourth lumbar vertabrae (L4) were measured in anesthetized rats using a dual energy X-ray absorpiometer (Eclipse XR-26, Norland Corp. Ft. Atkins, Wis.). The dual energy X-ray absorptiometer (DXA) measurements for each rat were performed as follows: Fifteen minutes prior to DXA measurements, the rat was anesthetized with an intraperitoneal injection of 100 mg/kg ketamine (Bristol Laboratories, Syracuse, N.Y.) and 0.75 mg/kg acepromazine (Aveco, Ft.Dodge, Iowa). The rat was placed on an acrylic table under the DXA scanner perpendicular to its path; the limbs were extended and secured with paper tape to the surface of the table. A preliminary scan was performed at a scan speed of 50 mm/second with a scan resolution of 1.5 mm×1.5 mm to determine the region of interest in PT and L4. Small subject software was employed at a scan speed of 10 mm/second with resolution of 0.5 mm×0.5 mm for final BMD measurements. The software allows the operator to define a 1.5 cm wide area to cover the total length of L4. The BMDs for respective sites were computed by the software as a function of the attenuation of the dual beam (46.8 KeV and 80 KeV) X-ray generated by the source underneath the subject and the detector travelling along the defined area above the subject. The data for BMD values (expressed in g/cm2) and individual scans were stored for statistical analysis. One week after BMD evaluation the rats were sacrificed by carbon dioxide suffocation and blood collected for cholesterol determination. The uteri were removed and the weights taken. Total cholesterol is determined using a Boehringer-Mannheim Hitachi 911 clinical analyzer using the Cholesterol/HP kit. Statitstics were compared using one-way analysis of variance with Dunnet's test.
