Definitions
- the present invention relates to the use of new 2-Phenyl-1-[4(2-Aminoethoxy)-Benzyl]-Indole compounds which are useful as estrogenic agents, in conjunction with estrogens, as well as pharmaceutical compositions and methods of treatment utilizing these compounds.
- 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, 176-estradiol, esterified estrogens, or conjugated estrogens isolated from natural sources (i.e. Premarin® conjugated estrogens from Wyeth-Ayerst) or synthetic estrogens.
- 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.
- Raloxifene a benzothiophene antiestrogen
- tissue selective estrogens is seen in the article “Tissue-Selective Actions Of Estrogen Analogs”, Bone Vol. 17, No. 4, October 1995, 181S-190S.
- WO A 95 17383 (Karo Bio AB) describes indole antiestrogens with long straight chains.
- Another related patent WO A 93 10741 describes 5-Hydroxyindoles with a broad range of side chains.
- WO 93/23374 (Otsuka Pharmaceuticals, Japan) describes compounds sharing structural similarities with those of the present invention, except with the structure referred to as R 3 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.
- U.S. Pat. No. 4,894,373 (Young) teaches the use of antiestrogens, including clomiphene and its isomers, citrates and derivatives, in the absence of estrogen for treating menopausal symptoms and treating or preventing osteoporosis.
- U.S. Pat. No. 5,552,401 (Cullinan et al.) describes benzodhophene compounds as usefull for the treatment of various medical indications associated with post-menopausal syndrome, and uterine fibroid disease, endometriosis, and aortal smooth muscle cell proliferation, the compounds being used in pharmaceutical formulations optionally containing estrogen or progestin.
- 5,646,137 and 5,591,753 discloses methods of treating osteoporosis with formulations of raloxefine-type arylbenzothiophene compounds in conjunction with a progestin selected from medroxyprogesterone, norethindrone or norethynodrel, or pharmaceutically acceptable salts thereof.
- a progestin selected from medroxyprogesterone, norethindrone or norethynodrel, or pharmaceutically acceptable salts thereof.
- 5,550,107 claims an invention comprising the treatment of breast or endometrial cancer with an antiestrogen together with at least one compound selected from the group of an androgen, a progestin, at least one inhibitor of sex steroid formation, expecially 17 ⁇ -hydroxysteroid dehydrogenase and aromatase activity, at least one inhibitor of prolactin secretion, one inhibitor of growth hormone secretion and one inhibitor of ACTH secretion.
- U.S. Pat. No. 5,672,609 discloses pyridine compounds useful in treating post menopausal syndrome and formulations therefore containing estrogen or progestin.
- U.S. Pat. No. 5,534,527 Black et al. teaches the use of aroylbenzothiophenes and estrogens in the inhibition of bone loss.

- the primary target tissues for estrogens include the reproductive tract (ovary; uterus; vagina), mammary tissue, skeleton, cardiovascular system and the central nervous system (CNS).
- the reduction in circulating estrogens results in a number of changes.
- a change in lipid profile occurs with increases in Low Density Lipoprotein (LDL) and decreases in High Density Lipoprotein (HDL) commonly measured and an associated increased risk of a cardiovascular event (heart attack, stroke).
- LDL Low Density Lipoprotein
- HDL High Density Lipoprotein
- Changes in the central nervous system include an increase in vasomotor symptoms (hot flush) and potentially changes in cognition and memory.
- Estrogen replacement therapy normalizes some of these changes, particularly those associated with the cardiovascular system (reduced LDL, increased HDL, reduced risk of heart attack), the skeleton (maintenance of bone mass, reduced fracture risk), and central nervous system (reduction in frequency and severity of the hot flush). While the reproductive tract responds, it is not all positive. On the positive side, vaginal dryness is alleviated. However, negative uterine responses include hypertrophy and hyperplasia, along with some menstrual-like bleeding. The breast is also affected and there are data correlating exogenous estrogen therapy with an increased risk of breast cancer.
- estrogens in combination with a progestin to reduce uterine stimulation. While the risks of endometrial cancer are reduced to non-hormone treated levels, the other side effects of progestins reduce compliance in women on hormone replacement.
- TSE tissue selective estrogen
- the tissue selective estrogen (TSE) compounds of this invention provide positive skeletal and cardiovascular affects similar to estrogens, without the negative effects associated with the uterus and breast.
- the combinations of TSEs and estrogens derive the positive effects of estrogens on the CNS, bone and cardiovascular, with the combination providing complimentary or additive effects on the bone and cardiovascular systems.
- the major variable is the TSEs ability to block estrogenic influence on the uterus and breast, which are the two major negative effects of unopposed estrogens.

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.
- each rat was evaluated for bone mineral density (BMD).
- BMD bone mineral density
- the BMD's of the proximal tibiae (PT) and fourth lumbar vertabrae (L4) were measured in anesthetized rats using a dual energy X-ray absorptiometer (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 ketarmine (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.
- DXA dual energy X-ray absorptiometer
- 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 BMs 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.
Abstract
The present invention relates to new formulations containing one or more estrogens and 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, which have the general structures below:
Description
- This application claims the benefit of U.S. Provisional Application No. 60/109,809, which was converted from U.S. patent application Ser. No. 09/079,561, filed May 15, 1998, pursuant to a petition filed under 37 C.F.R. 1.53(c)(2)(i).
- The present invention relates to the use of new 2-Phenyl-1-[4(2-Aminoethoxy)-Benzyl]-Indole compounds which are useful as estrogenic agents, in conjunction with estrogens, as well as pharmaceutical compositions and methods of treatment utilizing these compounds.
- 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, 176-estradiol, esterified estrogens, or conjugated estrogens isolated from natural sources (i.e. Premarin® conjugated estrogens from Wyeth-Ayerst) or synthetic estrogens. 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 are less clear, but are 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 ovariectormized 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 ovariectormized 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.
- 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 structural similarities with the present compounds, but are functionally different. For: compounds containing a basic amine, there is no phenyl group to rigidify the side chain.
- WO A 95 17383 (Karo Bio AB) describes indole antiestrogens with long straight chains. Another related patent WO A 93 10741 describes 5-Hydroxyindoles with a broad range of side chains. WO 93/23374 (Otsuka Pharmaceuticals, Japan) describes compounds sharing structural similarities with those of the present invention, except with the structure referred to as 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.
- In their article Postmenopausal Hormone replacement therapy with estrogen periodically supplemented with antiestrogen, Am. J. Obstet. Gynecol., Vol. 140, No. 7, 1981, pp. 787-792, Kauppila et al. describe their study of postmenopausal estrogen therapy of seven-week estrogen regimens followed by 10-day treatments with the antiestrogen clomiphene citrate.
- Also, in their article Comparison of Megestrol Acetate and Clomiphene Citrate as Supplemental Medication in Posmenopausal Oestrogen Replacement Therapy, l Arch. Gynecol. (1983) 234:49-58, Kauppila et al. describe combination therapies in postmenopausal women of estrogen with random supplementation of megestrol acetate or clomiphene citrate.

- The invention includes sulfate, sulfamates 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 dialkylphosphates 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.
- 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
-
- 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, deprotection 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.
- 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 3position 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 nitrite. 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.
- Synthesis of selected representative examples are given in the following schemes:
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.
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.
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. - 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-Cloroindole No. 142, thus obtained, is taken to the final product in analogous fashion to that shown in scheme 3.
- 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.
- The compounds of Formulas (I) and (II) are partial estrogen agonists and display high affinity for the estrogen receptor. Unlike many estrogens, however, 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. These compounds are useful in treating or preventing mammal disease states or syndromes which are caused or associated with an estrogen deficiency. This tissue selectivity allows their use for desirable estrogenic activity in certain tissues, such as bone, while limiting that activity in others, such as uterine tissue.
- Estrogens useful in the formulations of this invention include estrone, estriol, equilin, estradiene, equilenin, ethinyl estradiol, 17β-estradiol, 17α-dihydroequilenin, 17β-hydroequilenin (U.S. Pat. No. 2,834,712), 17α-dihydroequilin, 17β-dihydroequilin, menstranol and conjugated estrogenic hormones, such as those in Wyeth-Ayerst Laboratories' Premarin® products. Phytoestrogens, such as equol or enterolactone, may also be used in the present formulations and methods. A preferred embodiment of this invention comprises pharmaceutical compositions and methods of treatment utilizing conjugated estrogenic hormones, such as those in Wyeth-Ayerst Laboratories' Premarin® products, with one or more compounds of Formulas (I) or (III) listed herein. Esterified estrogens, such as those sold by Solvay Pharmaceuticals, Inc. under the Estratab® tradename, may also be used with the present formulations. Also preferred for use with the present invention are the salts of the applicable estrogens, most preferably the sodium salts. Examples of these preferred salts are Sodium estrone sulfate, Sodium equilin sulfate, Sodium 17alpha-dihydroequilin sulfate, Sodium 17alphaestradiol sulfate, Sodium Delta8,9-dehydroestrone sulfate, Sodium equilenin sulfate, Sodium 17beta-dihydroequilin sulfate, Sodium 17alpha-dihydroequilenin sulfate, Sodium 17beta-estradiol sulfate, Sodium 17beta-dihydroequilenin sulfate, Estrone 3-sodium sulfate, Equilin 3-sodium sulfate, 17alpha-Dihydroequilin 3-sodium sulfate, 3beta-Hydroxy-estra-5(10),7-dien-17-one 3-sodium sulfate, 5alpha-Pregnan-3beta-20R-diol 20-sodium sulfate, 5alpha-Pregnan-3beta,16alpha-diol-20-one 3-sodium sulfate, delta(8,9)-Dehydroestrone 3-sodium sulfate, Estra-3beta, 17alpha-diol 3-sodium-sulfate, 3beta-Hydroxy-estr-5(10)-en-17-one 3-sodium sulfate or 5alpha-Pregnan-3beta,16alpha,20R-triol 3-sodium sulfate. Preferred salts of estrone include, but are not limited to, the sodium and piperate salts.
- The present compounds of Formulas (I) and (II) are tissue selective compounds having the ability to behave like estrogen agonists, such as by lowering cholesterol and preventing bone loss, or like estrogen antagonists. Therefore, these compounds in the present formulations are useful for treating many maladies including osteoporosis, prostatic hypertrophy, infertility, breast cancer, endometrial hyperplasia, endometrial cancer, endometriosis, cystic glandular hyperplasia, uterine hyperplasia, cervical hyperplasia, benign prostatic hyperplasia, cardiovascular disease, contraception, Alzheimer's disease and melanoma The formulations of this invention may also be used to treat bone loss resulting from secondary osteoporosis, including that categorized as endocrine in nature, including that resulting from glucocorticoid excess, hyperparathyroidism, hyperthyroidism, hypogonadism, hyperprolactinemia, and diabetes mellitus. The bone loss may also be the drug-induced, such as that resulting from heparin treatments, alcohol consumption, or the use of tobacco, barbiturates or corticosteroids. The drug-induced loss of bone may also stem from treatment with gonadotropin releasing hormone (GnRH or LHRH) or synthetic GnRH antagonists or agonists, such as the leuprolide acetate injectable sold by TAP Pharmaceuticals Inc. under the tradename LUPRON® or the goserelin acetate implant sold by Zeneca Pharmaceuticals under the Zoladex® tradename. Such bone loss may also result from immobilization of the individual, chronic renal failure, malabsorption syndrome, hepatic disease, chronic obstructive lung disease, rheumatoid arthritis, or sarcoidosis.
- Additionally, these formulations can be used for hormone replacement therapy in post-menopausal women or in other estrogen deficiency states where estrogen supplementation would be beneficial. The symbiotic activity of the compounds and estrogen(s) of the present methods of treatment are particularly of interest in overcoming the unwanted consequences of estrogen therapy, such as breakthrough bleeding and/or excessive endometrial stimulation, which may lead to endometrial hyperplasia or endometriosis. These formulations, therefore, may be used in methods of treating or preventing excessive estrogenic uterine stimulation in a mammal.
- The formulations of this invention may also be used in methods of treatment for bone loss, which may result from an imbalance in an 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 hysterectomy/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 replacement can also be addressed using these formulations in individuals with bone fractures, defective bone structures, and those receiving bone-related surgeries and/or the implantation of prosthesis. In addition to those problems described above, these formulations can be used in treatments for osteoarthitis, Paget's disease, osteomalacia, osteohalisteresis, endometrial cancer, 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 Formulas (I) and (II), or a pharmaceutically acceptable salt thereof, in conjunction with a therapeutically desirable amount of an estrogen. This invention also includes pharmaceutical 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.
- Estrogens regulate a number of physiological processes. The primary target tissues for estrogens include the reproductive tract (ovary; uterus; vagina), mammary tissue, skeleton, cardiovascular system and the central nervous system (CNS). The reduction in circulating estrogens results in a number of changes. There is a cessation in reproductive function with an associated amenorrhea, uterine atrophy, and increase in vaginal dryness (lack of keratination). Mammary tissue becomes relatively quiescent. There is an increase in the rate of loss of bone mass (2-7%) compared to the normal 0.5-1.0%/year that is seen in all individuals over the age of 35. A change in lipid profile occurs with increases in Low Density Lipoprotein (LDL) and decreases in High Density Lipoprotein (HDL) commonly measured and an associated increased risk of a cardiovascular event (heart attack, stroke). Changes in the central nervous system include an increase in vasomotor symptoms (hot flush) and potentially changes in cognition and memory.
- Estrogen replacement therapy (ERT) normalizes some of these changes, particularly those associated with the cardiovascular system (reduced LDL, increased HDL, reduced risk of heart attack), the skeleton (maintenance of bone mass, reduced fracture risk), and central nervous system (reduction in frequency and severity of the hot flush). While the reproductive tract responds, it is not all positive. On the positive side, vaginal dryness is alleviated. However, negative uterine responses include hypertrophy and hyperplasia, along with some menstrual-like bleeding. The breast is also affected and there are data correlating exogenous estrogen therapy with an increased risk of breast cancer.
- Currently, women with intact uteri are generally not prescribed estrogens alone, but estrogens in combination with a progestin to reduce uterine stimulation. While the risks of endometrial cancer are reduced to non-hormone treated levels, the other side effects of progestins reduce compliance in women on hormone replacement.
- The tissue selective estrogen (TSE) compounds of this invention provide positive skeletal and cardiovascular affects similar to estrogens, without the negative effects associated with the uterus and breast. The combinations of TSEs and estrogens derive the positive effects of estrogens on the CNS, bone and cardiovascular, with the combination providing complimentary or additive effects on the bone and cardiovascular systems. The major variable is the TSEs ability to block estrogenic influence on the uterus and breast, which are the two major negative effects of unopposed estrogens.
- It is understood that the-dosage, regimen and mode of administration of these compounds of Formulas (I) and (II) will vary according to the malady and the individual being treated and will be subjected to the judgment of the medical practitioner involved. It is preferred that the administration of one or more of the compounds herein begins at a low dose and be increased until the desired effects are achieved. Similarly, it will be understood that the dosage(s) of the estrogen(s) utilized in the present formulations will be selected according to conventional methods. It is most preferred that the dosage will be monitored to achieve the desired result with the minimum of estrogen(s) necessary.
- Effective administration of these compounds of Formulas (I) and (II) may be given at a dose of from about 0.01 mg/day to about 1,000 mg/day. Preferably, administration will be from about 1 mg/day to about 600 mg/day in a single dose or in two or more divided doses. Most preferably a daily dose of between about 1 mg/day and about 150 mg/day will be administered.

- The compounds of this invention can be formulated neat or with a pharmaceutical carrier for administration, the proportion of which is determined by the solubility and chemical nature of the compound, chosen route of administration and standard pharmacological practice. The pharmaceutical carrier may be solid or liquid.
- A solid carrier can include one or more substances which may also act as flavoring agents, lubricants, solubilizers, suspending agents, fillers, glidants, compression aids, binders or tablet-disintegrating agents; it can also be an encapsulating material. In powders, the carrier is a finely divided solid which is in admixture with the finely divided active ingredient. In tablets, the active ingredient is mixed with a carrier having the necessary compression properties in suitable proportions and compacted in the shape and size desired. The powders and tablets preferably contain up to 99% of the active ingredient. Suitable solid carriers include, for example, calcium phosphate, magnesium stearate, talc, sugars, lactose, dextrin, starch, gelatin, cellulose, methyl cellulose, sodium carboxymethyl cellulose, polyvinylpyrrolidine, low melting waxes and ion exchange resins.
- Liquid carriers are used in preparing solutions, suspensions, emulsions, syrups, elixirs and pressurized compositions. The active ingredient can be dissolved or suspended in a pharmaceutically acceptable liquid carrier such as water, an organic solvent, a mixture of both or pharmaceutically acceptable oils or fats. The liquid carrier can contain other suitable pharmaceutical additives such as solubilizers, emulsifiers, buffers, preservatives, sweeteners, flavoring agents, suspending agents, thickening agents, colors, viscosity regulators, stabilizers or osmo-regulators. Suitable examples of liquid carriers for oral and parenteral administration include water (partially containing additives as above, e.g. cellulose derivatives, preferably sodium carboxymethyl cellulose solution), alcohols (including monohydric alcohols and polyhydric alcohols, e.g. glycols) and their derivatives, lethicins, and oils (e.g. fractionated coconut oil and arachis oil). For pareateral administration, the carrier can also be an oily ester such as ethyl oleate and isopropyl myristate. Sterile liquid carriers are useful in sterile liquid form compositions for parenteral administration. The liquid carrier for pressurized compositions can be halogenated hydrocarbon or other pharmaceutically acceptable propellant.
- Liquid pharmaceutical compositions which are sterile solutions or suspensions can be utilized by, for example, intramuscular, intraperitoneal or subcutaneous injection. Sterile solutions can also be administered intravenously. The compounds of this invention can also be administered orally either in liquid or solid composition form.
- The compounds of this invention may be administered rectally or vaginally in the form of a conventional suppository, creams, gels, etc. For administration by intranasal or intrabronchial inhalation or insufflation, the compounds of this invention may be formulated into an aqueous or partially aqueous solution, which can then be utilized in the form of an aerosol. The compounds of this invention may also be administered transdermally through the use of a transdermal patch containing the active compound and a carrier that is inert to the active compound, is non toxic to the skin, and allows delivery of the agent for systemic absorption into the blood stream via the skin. The carrier may take any number of forms such as creams and ointments, pastes, gels, and occlusive devices. The creams and ointments may be viscous liquid or semisolid emulsions of either the oil-in-water or water-in-oil type. Pastes comprised of absorptive powders dispersed in petroleum or hydrophilic petroleum containing the active ingredient may also be suitable. A variety of occlusive devices may be used to release the active ingredient into the blood stream such as a semipermeable membrane covering a reservoir containing the active ingredient with or without a carrier, or a matrix containing the active ingredient. Other occlusive devices are known in the literature.
- The dosage requirements vary with the particular compositions employed, the route of administration, the severity of the symptoms presented and the particular subject being treated. Treatment will generally be initiated with small dosages less than the optimum dose of the compound. Thereafter the dosage is increased until the optimum effect under the circumstances is reached; precise dosages for oral, parenteral, transdermal, rectal or vaginal suppositories, nasal, or intrabronchial and other administrations will be determined by the administering physician based on experience with the individual subject treated. Preferably, the pharmaceutical composition is in unit dosage form, e.g. as tablets or capsules. In such form, the composition is sub-divided in unit dose containing appropriate quantities of the active ingredient; the unit dosage forms can be packaged compositions, for example, packeted powders, vials, ampoules, prefilled syringes or sachets containing liquids. The unit dosage form can be, for example, a capsule or tablet itself, or it can be the appropriate number of any such compositions in package form.
- The compound(s) of Formulas (I) and (II) and the estrogen(s) of the present formulations may be administered in separate dosage units, such as separate pills, tablets, powders, etc., or combined into one formulation. When optimum dosages for the compounds of Formulas (I) and (II) and the estrogens of these formulations have been determined, it may preferable to incorporate both into a single formulation for ease of administration. It is also understood that the formulations herein may or may not include other pharmaceutically active components.
- Solvents used for the reactions described herein were anhydrous Aldrich Sure Seal™ without further purification. Reagents were typically Aldrich and used without further purification. 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 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. Analysis values for compounds with CHN analysis reported were within 0.4% of theoretical values.
- 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.

- 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).
- 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+1 H2O.
- 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).
- 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.

The reaction flask was heated to 105° C. for no more than 20 min. During the heating period, the reaction was monitored carefully by TLC for the disappearance of the starting material. The progress of the reaction could be shown as the product solidified out of the solution while heating. The reaction was then cooled to rt and more product crashed out was observed. The reaction content was poured into a separatory funnel containing ether (100 mL) and H2O (200 mL), which was shaken vigorously. The insoluble residue as the desired product stayed in the ether layer which was collected by vacuum filtration. The product was further purified by trituration in ether to give a light gray solid (4.4 g, 46%)

- Biological Data
- In vitro Estrogen Receptor Binding Assay
- Receptor Preparation
- 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
- The competition assay was performed in a 96-well plate (polystyrene*) which binds <2.0% of the total 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-etradiol 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 centnfuged 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-stradiol, 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
- 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 - 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. For a description of these methods, see Hulme, E. C., ed. 1992. Receptor-Ligand Interactions: A Practical Approach. IRL Press, New York. (see especially chapter 8).

- Ishikawa Cell Alkaline Phosphatase Assay
- Cell Maintenance and Treatment:
- Ishikawa cells were maintained in DME 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 (treent 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 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:
- 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 X-100) is added to each well. Plates are placed at −80° C. for a minimum of 15 minutes. Plates are thawed at 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).
- 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 17,stradiol.
- 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 - A description of these methods is described by Holinka, C. F., Hata, H., Kuramoto, H. and Gurpide, E.

- Cell Maintenance and Treatment
- Chinese Hamster Ovary cells (CHO) which had been stably transfected with the human estrogen receptor were maintained in DME+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 (eminent medium). Cells were plated at a density of 5000 cells/well in 96-well plates containing 200 μL of medium/well.
- Calcium Phoshate Transfection
- 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:
10 uG of reporter DNA 5 uG of pCH110DNA 5 uG of pTZ18U 20 uG of DNA/1 mL of transfection solution - The DNA (20 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
- 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.
Infection Luciferase Assay (Standards) Compound % Activation 17β-estradiol 100% activity estriol 38% activity tamoxifen 0% activity (10% with 1 nM 17β-estradiol) raloxifene 0% activity (0% with 1 nM 17β-estradiol)
B-Galactosidase Assay - To the remaining 5 uL of lysate 45 uL of PBS was added. Then 50 uL of Promega B-galactosidase 2× assay buffer 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
- 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-stradiol 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 transactivational capacity was determined by both cellular and promoter context and mediated by two functionally distinct intramolecular regions (see Molecular Endocrinology, 8:21-30).

- 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.

- 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.
- 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 absorptiometer (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 ketarmine (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 BMs 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.
