TECHNICAL FIELD
The present invention relates to a novel compound, which is a selective estrogen receptor modulator.
BACKGROUND ART
Estrogen is a “female hormone” whose various physiological activities have been described in a number of references (for instance, D. S. Loose-Mitchell and G. M. Stancel, Goodman and Gilman's, The Pharmacological Basis of Therapeutics, 10th Ed., J. G. Hardman and L. E. Limbird Eds, 2001, p. 1597-1634). In addition, estrogen regulates the development and function of the reproduction system, and affects a variety of physiological function (including maintenance of vaginal inner layer, retention of bone density and temperature regulation). In recent years, investigations showed that estrogen has a number of function other than physiological functions associated with female reproduction and genital tissue functions. On the other hand, in males, it is also known that estrogen is present in the body, and that the estrogen receptor is present in a variety of tissues (for instance, G. Lombardi et al., Mol Cell Endocrinol, 2001, Vol. 178 (1-2), p. 51-55). In addition, estrogen decreases low density lipoproteins (LDLs) and regulates the production of cholesterol in liver. Furthermore, estrogen is thought to be involved in decreasing the risk of manifestation of Alzheimer's disease, and to alleviate the manifestation thereof (for instance, V. W. Henderson, Neurology, 1997, Vol. 48, (5 Suppl 7), S27-35).
Thus, estrogen is involved in a variety of functions in vivo, and when estrogen can no longer be produced, physiologically important alterations arise. Among others, estrogen production in healthy females is known to decrease sharply at menopause. Examples of effects of decrease in estrogen production include, in addition to the problems of urinary incontinence, vaginal dryness and decrease in skin tone, the problems of neurological symptoms, emotional instability and modulation of temperature regulation, as well as increase in blood lipid (leading to a large increase of the occurrence of cardiac diseases) and decrease in bone density (osteoporosis) and the like.
For example, in addition to urinary incontinence, vaginal dryness, increase in the rate of incidence of autoimmune diseases and loss of skin tone, problems related to the increase in the occurrence of autoimmune diseases, vasomotor complications (hot flashes), and neurological symptoms and the like, are symptoms which are associated with menopause, and are known to be alleviated or improved by estrogen replacement therapy.
However, estrogen administration leads to the increase of serious dangers such as breast cancer and endometrial cancer as well as thrombus formation.
A estrogen-dependent breast cancer is an example of pathological state associated with abnormal cell response to endogenous tissue estrogen. Estrogen-dependent tumor cells proliferate in the presence of estrogen. Current chemotherapies against these cancers largely rely on the use of anti-estrogen compounds, for instance, tamoxifen. Altough such estrogen agonists-antagonists have beneficial effects in the treatment of these cancers and are acceptable in situations where adverse events of estrogen is life-threatening, they are not ideal. For instance, these agents, due to the estrogen (agonist) characteristics that they have, sometimes exhibit estrogenic stimulation of a group of cancer cells present in the uterus. A better therapy to treat these cancers is an agent, which is an anti-estrogen compound whose estrogen agonist characteristics may be ignored against the proliferating tissue or is completely inexistent.
Another estrogen-dependent symptom is uterine fibrosis (uterine fibroid tumor disease). This uterine fibrosis is fundamentally a state where a deposition of fibroid tissue is present on the uterine wall. This state is responsible for dysmenorrhea and infecundity in females. Except for the suggested evidence of an inadequate response of the fibroid tissue to estrogen, the exact cause of this state is not well known. The most general treatment of uterine fibrosis include surgical operations, which is expensive and sometimes cause complications such as abdominal adhesion and infection and the like.
In addition, another estrogen-dependent disease is endometritis, a serious dysmenorrhea state accompanied by sharp pain and hemorrhage into the endometrial mass or peritonea, often leading to infecundity. The cause for the occurrence of this state is thought to be the growth of a heterotropic endometrium present in an inadequate tissue, which respond inadequately to a normally hormonal regulation.
For a long time, estrogen replacement therapy has been practised for a number of important health problems caused by the inability to produce estrogen; however, due to an increase in the adverse effects and risks thereof, the use thereof became limited.
In addition, in case of problems related to osteoporosis caused by estrogen being no longer produced, one of the most general types of osteoporosis is associated with menopause. Here, osteoporosis means a group of diseases resulting from various causes of disease, and is characterized by the net loss of bone mass. This loss of bone mass and the resulting fracture lead to weakening of the skeleton that sufficiently maintains the body in structural terms. The majority of females lose approximately 20% to approximately 60% of bone mass in the trabecular constituent portion of the bone within 3 to 6 years after missed menstruation. Osteoporosis is a general and serious illness for postmenopausal females. Osteoporosis induces psychological damages to patients and family members; in addition, due to the chronical nature of this disease, large economical losses are sustained, and wide-range and lengthy care (hospitalization and home care nursing) is required due to the aftereffects of this illness. An excellent method for treating osteoporosis is estrogen replacement therapy (for instance, R. L. Prince et al., N. Engl. J. Med., 1991, Vol. 325, p. 1189-1195 and J. E. Compston, Physiol Rev, 2001, Vol. 81, p. 419-447). As mentioned above, estrogen therapy often provokes undesirable adverse effects, in particular in uterine and mammary tissues, the use of estrogen is limited, although this therapy has a therapeutic effect.
Further, in case of cardiovascular related problems, it has been long known that during the premenopausal period, the rate of incidence of cardiovascular illness for a majority of females is lower than males of the same age. However, at postmenopause, the rate of incidence of cardiovascular illness in females increases slowly in comparison to the proportion seen in males. This increase in rate of incidence is associated with a loss of estrogen, and particularly to a loss of estrogen that adjusts the serum lipid level. Postmenopausal females receiving estrogen replacement therapy have been reported to make their cardiovascular protection improve to a level that is equivalent to premenopausal state. Therefore, estrogen is thought to be a rational treatment for this state (for instance, M. E. Mendelsohn et al., N. Engl. J. Med., 1999, Vol. 340, p. 1801-1811). However, the adverse effects of estrogen replacement therapy cannot be accepted by a number of females, such that the use of this therapy is limited.
Meanwhile, Alzheimer's disease (hereinafter referred to as “AD”) is clinically a regressive neurodegenerative disease characterized by the gradual loss of memory, recognition, deduction, judgement and emotional stability, provoking gradually remarkable psychological depression and ultimately leading to death. AD is a general cause of progressive psychological impairment (dementia) in the elderly, and in the U.S. it is believed to be the 4th general medical cause of death. AD is observed in a variety of populations and ethnic groups in the world and represents a present and future major public health problem. The frequency of occurrence of this disease increases with age, and approximately 10% of the elderly population of 65 years and older is estimated to be affected (for instance, Evans et al., J. Amer. Med. Assoc., 1989, Vol. 262, p. 2551-2556). Thus far, AD has been shown to be incurable, and AD is expected to multiply in the world as human life span becomes longer.
Several studies in human have shown that the use of estrogen prevented the decline of the recognition function, then led to recovery (for instance, B. B. Sherwin, Psychoneuroendocrinology, 1988, Vol. 13, No. 4, p. 345-357 and T. Duka et al., Psychopharmacology, 2000, Vol. 149, No. 2, p. 129-139). Several epidemiological studies reported that the use of estrogen also decreases the risk of AD episode (for instance, V. W. Henderson, Neurology, 1997, Vol. 48, (5 Suppl 7), S27-35). In addition, estrogen appears to improve recognition function in AD patients (for instance, Ohkura et al., Endocrine J, 1994, Vol. 41, p. 361-371 and V. W. Henderson, CNS Drugs, 1997, Vol. 8, No. 5, p. 343-351). Further, estrogen is known to possess an action of protecting nerve cells, which are beneficial to the treatment of neurodegenerative diseases such as AD, and an action of activating neurotrophic factors. However, the use of estrogen is also associated with a number of disadvantageous adverse effects including the increase in the risk of breast cancer and uterine cancer. It is possible that estrogen agonists or antagonists, while maintaining a large number of estrogen actions, lack adverse effects on tissues such as mammary gland and uterus.
Thus far, the discovery that a number of agents worked as estrogen agonists on some tissues (for instance, bone) and as antagonists on other tissues (for instance, mammary gland) provided effective treatments for symptoms provoked by a decrease in estrogen or estrogen-dependent diseases. Best known among these so-called selective estrogen receptor modulators (hereinafter referred to as “SERM”), tamoxifen, that is 1-(4-β-dimethylaminoethoxyphenyl)-1,2-diphenylbut-1-ene, has been demonstrated to be therapeutically useful in the treatment and the prophylaxis of breast cancers, as well as in the decrease in LDL concentration. However, as tamoxifen simultaneously has an estrogenic stimulatory action on the uterus, it turned out to increase the risk of endometrial cancer.
In recent years, newer SERMs, for instance, raloxifene, that is 6-hydroxy-2-(4-hydroxyphenyl)-3-[4-(2-piperidinoethoxy)benzoyl]benz[b]thiophene, were reported to be, in regard to bone and lipid, similar to the desired action of estrogen, but in contrast to estrogen, uterine stimulation was minimal (for instance, Scrip, 1993, Apr. 16/20, No. 1812/13, p. 31 and Breast Cancer Research and Treatment, 1987, Vol. 10, No. 1, p. 31-36).
Raloxifene and related compounds are described as anti-estrogen substances and anti-androgen substances that are effective for the treatment of breast cancers and prostate cancers (for instance, U.S. Pat. No. 4,418,068 and Journal of Medicinal Chemistry, 1984, Vol. 27, No. 8, p. 1057-1066).
Other compounds such as those mentioned below are known as SERMs.
Derivatives of 2-phenyl-3-aroylbenzothiophene and 2-phenyl-3-aroylbenzothiophene-1-oxide, which are useful as contraceptive drugs and useful in inhibiting the growth of breast cancers, have been disclosed (for instance, U.S. Pat. No. 4,133,814).
An estrogen antagonist represented by the following formula;




(wherein R2 represents phenyl or cyclopentyl and R3 represents H,





or —CH2CHOHCH2OH) has been described (for instance, Journal of Medicinal Chemistry, 1969, Vol. 12, No. 5, p. 881-885).

Preparation of a series of tetrahydronaphthalenes intended to achieve the separation of estrogen activity, contraception activity, and hypocholesterolemia activity has been described. These structures are represented by the formula;




(wherein R1 represents H or OCH3; R2 represents H, OH, OCH3, OPO(OC2H5)2, OCH2CH2N(C2H5)2, OCH2COOH or OCH(CH3)COOH) (for instance, Journal of Medicinal Chemistry, 1967, Vol. 10, No. 2, p. 138-144).

An estrogen agonist and antagonist represented by the following formula;




have been disclosed (for instance, U.S. Pat. No. 6,204,286).

A compound represented by the following formula;




(wherein R3 represents a lower alkyl, R1 and R2 are selected from the group consisting of lower alkyls and 5 to 7 membered saturated heteocyclic ring formed by bonding lower alkyls to each other) has been disclosed (for instance, U.S. Pat. No. 3,274,213 and Journal of Medicinal Chemistry, 1967, Vol. 10, No. 1, p. 78-84).

An estrogenic compound represented by the following formula;




is disclosed (for instance, European patent application No. 802,183).

However, so far, there may be the current situation that no therapeutic agent exists, which is effective against symptoms caused by a decrease in estrogen and a variety of estrogen-dependent diseases and symptoms, furthermore, against central nervous system diseases including Alzheimer's disease. Therefore, there is a need for development of a compound that selectively has the activity which is an estrogen receptor modulator, and the property which is satisfactory as a desired medicine.

Test Example 1
In Vitro Estrogen Receptor Binding Assay
The binding affinity of the compound according to the present invention to estrogen receptor was measured using an in vitro estrogen receptor binding assay. The binding affinity measures the ability of the compound according to the present invention to remove [3H]-estradiol from estrogen receptor derived from bovine uterus. The following materials were used in this assay: (1) the assay buffer solution was 20 mM Tris/HCl (pH 7.5) containing 1 mM dithiothreitol (DTT), 1 mM EDTA and 10% glycerol; (2) radioactive ligand was [3H]-estradiol purchased from Amersham Life Science; (3) the cold ligand was diethylstilbestrol purchased from sigma (Sigma); and (4) the estrogen receptor was derived from bovine uterus.
The compound to be tested was prepared as a 10% DMSO solution. [3H]-estradiol was dissolved in the assay buffer solution so as to obtain a final concentration of 1 nM. The estrogen receptor derived from bovine uterus was diluted with the assay buffer solution so that 10 to 20 μg total protein was present in each assay well. Using a small titration plate, in each assay well were added a solution (10 μl) of cold diethylstilbestrol (non-specific binding) or compound, [3H]-estradiol (10 μl) and a solution (80 μl) of estrogen receptor derived from bovine uterus. Each plate contains total binding, non-specific binding and the binding which were not inhibited by various concentrations of the compound. The plate was incubated for 1 hour at room temperature. Then, by adding 2% charcoal dextran (100 μl) to the assay buffer solution, mixing and incubating the solution at room temperature for 10 minutes, the binding reaction was terminated. These mixtures were centrifuged, and the supernatent thereof was evaluated for its radioactivity using a liquid scintillation counter. Specific binding was calculated by subtracting non-specific binding dpm (counts remaining in the supernatant obtained by centrifugal separation of a reaction mixture containing estrogen receptor derived from bovine uterus, radioactive ligand and excess cold ligand) from the total binding dpm (counts remaining in the supernatant obtained by centrifugal separation of a reaction mixture containing estrogen receptor derived from bovine uterus and radioactive ligand only). The effectiveness of the compound was evaluated by Ki. Ki was determined according to the following calculation formula: Ki=IC50/(1+(C/Kd)), wherein IC50 (concentration of the compound required to inhibit the total specific [3H]-estradiol binding by 50%) is a value obtained by measuring the specific binding in the presence of various concentrations of the compound, then calculating the percentage of binding relative to the total specific binding and producing a plot with the latter as the vertical axis and the compound concentration (log scale) as the horizontal axis. C is the concentration of [3H]-estradiol in the reaction mixture, and Kd is the [3H]-estradiol dissociation constant. The Kd was determined by Scatchard analysis. That is to say, various concentrations of [3H]-estradiol were used to measure the concentration of specifically bound [3H]-estradiol, which served as the horizontal axis, the value which was obtained by dividing the concentration of specifically bound [3H]-estradiol by the concentration [3H]-estradiol not bound to the receptor served as the vertical axis to produce a plot, and the negative value of the inverse of the slope of the resulting straight line was used as Kd.
Results:
Tamoxifen, a well known selective estrogen receptor modulator, was used as a comparative example. Estrogen receptor binding affinity results for the compound according to the present invention are shown in the following (Table 1).

Test Example 2
MCF-7 Growth Analysis
Test Example 2 determines the estrogen agonist and antagonist activities of the compound according to the present invention in reproduction system cells. It shows that the higher the agonist activity, the less it is desirable in the reproduction system. On the other hand, the antagonist activity demonstrates that the compound is effective in the treatment of cancers whose growth is dependent on steroid hormones in particular breast cancers. The present test was carried out according to the following procedures. MCF-7 breast cancer cells were cultured in the preservation medium until the compound evaluation. The preservation medium is the MEM (minimum essential medium, phenol red-free, Gibco, ##51200-038) supplemented with 10% (volume/volume) fetal bovine serum (FBS), 2 mM L-glutamine, 1 mM sodium pyruvate, non-essential amino acids (0.1 mM, Gibco, #15240-062), and antibiotic-antimycotic solution ( 1/50 of culture medium volume, Gibco). Five days prior to analysis, the preservation medium was exchanged with analytical medium to which 10% charcoal-stripped fetal bovine serum (charcoal-FBS) was added instead of 10% FBS, so as to deprive the MCF-7 cells of endogenous steroids. Twenty-four hours after exchange to the analytical medium, the MCF-7 cells were removed from the preservation flask using cell isolation medium (trypsin-EDTA solution, Gibco). The cells were washed with analytical medium once, and cell suspension at 50,000 cell/ml was prepared using the analytical medium. The prepared cell suspension was added to a 96 well flat-bottomed microculture at 100 μl (5,000 cells) per well, the cells were cultured in a 5% CO2 incubator for 24 hours at 37° C., to equilibrate the cells after cell transfer. Serial dilution of dimethylsulfoxide (DMSO) solution of each drug was carried out using analytical medium to serve as a drug or diluent control, drug/DMSO solution was added to the microculture at 10 μl per well, then the analytical medium (10 μl) or 120 pM 17β-estradiol analytical medium solution (10 μl) was added for agonist activity assay or antagonist activity assay respectively so that the final volume of each well was set to 120 μl. The cells were further cultured in the 5% CO2 incubator for 72 hours at 37° C. After culturing, the cell growth was examined by the MTT assay. MTT assay was carried out as the following protocols. MTT solution at 8 mg/ml (MTT dissolved in phosphate saline water buffer) was added to the microculture at 10 μl/well, and the cells were cultured in the 5% CO2 incubator for 30 minutes at 37° C. Thereafter, resulting from the reduction of MTT by the cells, formazan crystals were dissolved by adding a dissolution buffer (400 g/l of an aqueous solution of SDS (50%) and dimethylformamide (50%)) to the microculture at 100 μl/well, and incubated the microculture for more than 4 hours in the dark. For each well of the microculture, the optical density at 590 nm due to the dissolved formazan crystals was measured.
The results of the evaluation of the compound according to the present invention by the above-mentioned test are shown below (Table 2). Identically to Test Example 1, tamoxifen, a well known selective estrogen receptor modulator, was used as the comparative example. The agonist activity is a value converted from the growth rate for 100 nM test compound, by taking the growth rate for the diluent control as 100, and the growth rate for 17β-estradiol (1 nM) as 200. The antagonist activity is a value obtained by measuring the concentration of test compound required to inhibit the growth by 50% (IC50) when culturing with 17β-estradiol (10 pM) and the test compound present simultaneously.

Effect of SERM Compounds on Bone Resorption in Ovariectomized Rats
Experimental Method
Animals
Ten weeks old Female Fischer rats (F344/N, Japan SLC, Shizuoka, Japan) were used. Rats were grouped to eliminate the effect of body weight between each group and housed with free access to food and water. Animals were anesthetized with Nembutal (Abbott Laboratories, Chicago, Ill.) and the ovaries were removed. In sham-operated group, ovaries were only touched with tweezers. Administration of compounds was started one day after the operation.
Drugs:
Estradiol (Sigma-Aldrich, St. louis, MO) was dissolved in DMSO to 150 mg/mL then diluted with sesame oil to 0.15 mg/mL. The compounds in Examples 736 and 814, and Raloxifene were suspended in sesame oil to 5, 5 and 1.5 mg/mL, respectively. Samples were divided into aliquots for daily administration and preserved at −18° C. until use.
Administration:
The samples were orally administered at 2 mL/kg. Administration was carried out once a day from Monday to Friday for 8 weeks.
The measurement of deoxypyridinoline in urine:
Urine was gathered overnight (17 hours) using the metabolic cage under fasting. The amount of urinary deoxypyridinoline was measured with ELISA kit, Osteorincs-DPD (Sumitomo Seiyaku Biomedical Co., Ltd., Osaka, Japan) and evaluated as total amount produced in 17 hours or as the amount per 1 mg of creatinine.
The measurement of bone density:
After animals were sacrificed by decapitation, left femur and the fifth lumbar vertebrae were removed. The bone density was measured by using QDR-1000/W (Hologic Inc., Bedford, Mass.).
The measurement of uterus wet weight:
After animals were sacrificed by decapitation, uterus was removed and adipose tissue and vagina was separated from uterus prior to uterus weight measurement.
Results
The results are summarized in Table 3, the results show the following effects;
The effects on excretion of deoxypyridinoline in urine:
Excretion of deoxypyridinoline in urinary was increased two-fold after ovariectomy over sham-operated rats. The compounds in Examples 736 and 814 significantly attenuated the excretion of deoxypyridinoline after 5 and 8 weeks administrations.
The effects on bone mineral density of femur and fifth lumbar vertebrae:
Eight weeks after ovariectomy, the bone mineral density of total femur, distal femur and fifth lumber vertebrae was decreased about 4, 5 and 10% compared with sham-operated rats, respectively. The compounds in Examples 736 and 814 preserved bone mineral density at the level in sham-operated rats.
The effects on uterus wet weight:
After eight weeks administrations, the compound in Example 736 did not influence the wet weight of the uterus at all. On the other hand, both Raloxifene and the compound in Example 814 slightly increased uterus wet weight to the same level.
