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 general structures (I) or (II).

Description

2-PHENYL-1-T4- (2-AMINOETOXY) -BENCIL] -INDOL IN COMBINATION WITH ESTROGENS DESCRIPTION OF THE INVENTION The present invention relates to the use of novel 2-phenyl-l- [4- (2-aminoethoxy) -benzyl] -indole compounds which are useful as estrogenic agents, together with estrogens, as well as with pharmaceutical compositions and methods of treatment using these compounds.
BACKGROUND OF THE INVENTION The use of replacement hormone therapy to prevent bone loss in postmenopausal women is well-founded. The usual protocol requires estrogen supplementation using formulations containing estrogan, estriol, ethinylestradiol, 17β-estradiol, esterified estrogens or conjugated estrogens isolated from natural sources (eg conjugated estrogens PremarinME from Wyeth-Ayerst) or synthetic estrogens. In some patients the therapy may be contraindicated due to the unopposed estrogen proliferative effects (estrogens that are not supplied in combination with progestins) and that are found on uterine tissue. This proliferation is Ftef: 124346"! - -" • 'nor mii? associated with an increased risk of endometriosis or endometrial cancer, or both. The effects of non-opposite estrogens on breast tissue are less clear, but they are often worrisome. The need for estrogen is evident, which can maintain a bone sparing effect and at the same time minimize the proliferative effects on the uterus and the breasts. It has been shown that certain non-steroidal antiestrogens maintain bone mass in the ovariectomized rat model as well as in human clinical trials. Tamoxifen (sold as the brand of tamoxifen citrate Novadex ™ by Zeneca Pharmaceuticals, Wilmington, Delaware) for example is a useful palliative for the treatment of breast cancer and has been shown to exert an effect similar to estrogen agonist in bone, in humans . However, it is also a partial agonist in the uterus and is the cause of some concern. It has been shown that raloxifene, a benzothiophene antiestrogen stimulates uterine growth in ovariectomized rats to a lesser degree compared to tamoxifen and at the same time maintains the ability to save bone. An adequate review of tissue selective oestrogens is observed in the article "Tissue-Selective Actions of Estrogen Analogs", Bone Vol. 17, No. 4 of October 1995, 181S-190S. The use of Índles as estrogen antagonists has been reported by Von Angerer, Chemical Abstracts, Vol. 99, No. 7, (1983), Extract No. 53886u. See also, J. Med. Chem. 1990, 33, 2635-2640; J. Med. Chem. 1987, 30, 131-136. See also Gerl Offen., DE 3821148 Al 891228 and WO 96/03375. These compounds of the prior art share structural similarities with the present compounds, but are functionally different. For compounds containing a basic amine, there is no phenyl group that stiffens 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 wide range of side chains. WO 93/23374 (Otsuka Pharmaceuticals, Japan) discloses compounds that share structural similarities with those of the present invention, except with the structure referred to as R3 in the present formulas I and II, in the following, the which is defined as thioalkyl and in the reference no such compounds are described with chains from the indole nitrogen having the same structure as those provided by the present invention. In the postmenopausal article Hormone replacement therapy wi th is trogen peri odi cal and s uppl emen ted wi th antiestrogen, Am. J. Obstet. Gynecol. , Vol. 140, No. 7, 1981, pp. 787-792, Kauppila et al. describe their postmenopausal estrogen therapy study of seven estrogen regimens weeks followed by treatments for 10 days with the antiestrogen clomiphene citrate. In addition, in his article Comparison of Megestrol Acétate and Clomiphene Ci treat as Supplemental Medication in Postmenopausal Oestrogen Replacement Therapy, Arch. Gynecol. (1983) 234: 49-58, Kauppila et al. describe combination therapies in postmenopausal women with estrogen and with random supplementation of megestrol acetate or clomiphene citrate. U.S. Patent No. 4,894,373 (Young) describes the use of antiestrogens, including clomiphene and its isomers, citrates and derivatives, in the absence of estrogen to treat menopausal symptoms and treat or prevent osteoporosis. U.S. Patent No. 5,552,401 (Cullinan et al.) Discloses benzothiophene compounds as being useful for the treatment of various medical indications associated with postmenopausal syndrome and uterine fibroid disease, endometriosis and proliferation of smooth muscle cells in the aorta , the compounds are used in pharmaceutical formulations that optionally contain estrogen and progestin. U.S. Patent Nos. 5,646,137 and 5,591,753 (both issued to Black et al.) Describe methods of treating osteoporosis with formulations of arylbenzothiophene compounds of the raloxefin type together with a progestin selected from medroxyprogesterone, norethindrone or norethinodrel, or a pharmaceutically acceptable salt thereof. U.S. Patent No. 5,550,107 (Labrie) 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 an inhibitor of the formation of sex steroids, especially 17β-hydroxysteroid dehydrogenase and aromatase activity, at least one inhibitor of prolactin secretion, an inhibitor of growth hormone secretion and an inhibitor of ACTH secretion. U.S. Patent No. 5,672,609 (Bryant et al.) Discloses pyridine compounds useful in treating postmenopausal syndrome and formulations that therefore contain estrogen or progestin. U.S. Patent No. 5,534,527 (Black et al.) Describes the use of aroylbenzothiophenes and oestrogens in the inhibition of bone loss.

Methods The compounds of this invention can be synthesized in a general sense according to Reaction Scheme 1, below.
Reaction scheme 1 NaH, DMF The initial indole synthesis is carried out by heating an α-bromo-ketone (b) appropriately substituted with the desired aniline (a) in DMF to form the indole (c). The product is then alkylated with benzyl chloride (e) to provide the substituted (f) indole. Benzyl chloride (e) can be easily prepared from 3 not substituted with chlorosulfonyl isocyanate, followed by tetylamine. A compound of the nitro group in position 3 can be prepared by treatment of the mdol with sodium nitrite and acetic acid. One skilled in the art recognizes that these routes are not limiting and that other routes are also available.
Reaction scheme 2 3 - . 3 -Deproteger 1-Protect nitrogen nitrogen 2-Functionalize position 4 -Add chain 3 with -X lateral The synthesis of the selected representative examples are provided in the following schemes: Reaction scheme 3 s- ~ rc? a ^ '^ -'. ^ The synthesis of the analogs with a 3 carbon chain (example No. 166) between the oxygen and the basic amine can be carried out as shown in reaction scheme 4.
Reaction scheme 4 EtOH / THF The synthesis procedure shown in the Reaction Scheme 4 can be used for compounds with two carbon chains analogous to Example No. 97 in Reaction Scheme 3. This is shown in Reaction Scheme 4 for the synthesis of Example No. 127.
Reaction diagram 4th CAS # [20886-03-7] CAS # [51388-20-6] Example No.17 Synthesis of indoles with alternative substituents (CN, Cl) at position 3 of indole use both 3-unsubstituted indole No. 141 for a precursor. Indole is synthesized by the Fisher Method using the hydrazone derived from the condensation of 4-benzyloxyacetophenone CAS No. [54696-05-8] and 4-benzyloxyphenylhydrazine CAS No. [51145-58-5]. Hydrazone No. 140 is then cyclized in acetic acid using zinc chloride to provide the desired indole No. 141. This synthesis can be seen in Reaction Scheme 5.
Reaction scheme 5 Example No. 141 The synthesis of the 3-chloroindole compounds is demonstrated for Example No. 134 and is shown below in Reaction Scheme 6. Indole No. 141 of Reaction Scheme 5 is chlorinated with N-chlorosuccinamide. The 3-chloroindole No. 142 obtained in this way is taken to the final product in a manner analogous to that shown in Reaction Scheme 3.
Reaction scheme 6 Example No. 141 Example No. 142 Same stages as in Reaction Scheme 3 The 3-cyano analogs are synthesized from the indole precursor No. 141 as shown in Reaction Scheme 7.
The reaction of the indole precursor No. 141 with chlorosulfonyl isocyanate followed by the addition of triethylamine provides 3-cyanoindole No. 155. The side chain is produced by conversion of a benzyl alcohol of CAS No. [111728-87-1] to a benzyl bromide No. 156 using thionyl bromide in THF. The indole is alkylated by the side chain in DMF using sodium hydride to provide the intermediate No. 157. This can then be taken for the final product No. 138 in a manner analogous to that shown in Reaction Scheme 4.
Reaction scheme 7 Example No. 141 Example No. 155 2-Et3N [111728-87-1P] Example No. 156 NaH DMF Example No. 138 Compounds 3e formulas (I) and (II) are partial estrogen agonists and show high affinity for the estrogen receptor. However, unlike many estrogens, these compounds do not cause increases in wet uterine 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 for treating or preventing morbid states in mammals or syndromes which are caused or associated with an estrogen deficiency. This tissue selectivity allows its use for desirable estrogenic activity in certain tissues, such as bone, and at the same time limits this activity in others, for example as uterine tissue. Estrogens useful in the formulations of this invention include estrone, estriol, equilin, estradiene, equilenin, eti ni 1 is radiol, 17 β-estr adi ol, 17a-dihydroequilenin, 17β-dihydroequilenin (U.S. Patent No. 2,834,712), 17a-dihydroequilin, 17β-dihydroequilin, menstranol, and conjugated estrogenic hormones such as the products of Premarin "* from Wyeth-Ayerst Laboratories 1. Also, phytoestrogen methods such as equol or enterolactone can be used in the present formulations and a preferred embodiment of this invention. comprises pharmaceutical compositions and methods of treatment using conjugated estrogenic hormones such as those of the products Premarin "" from Wyeth Ayerst Laboratories with 1 or more compounds of formula (I) or (III) included herein. Estergenic esters, such as those sold by "olvay Pharmaceuticals Inc." under the tradename Estratab "" can also be used with the present formulations. Salts of the applicable estrogens are also preferred for the use of the present invention, more preferably sodium salts. Examples of these preferred salts are estrone sodium sulfate, equilin sodium sulfate, sodium alkale dihydroequiline sulfate, sodium 17alpha-estradiol sulfate, delta 8, 9-sodium dehydroestrone sulfate, sodium equilenin sulfate, 17beta dihydroequiline sulfate sodium, 17alpha dihydroequilenine sodium sulfate, 17beta-estradiol sodium sulfate, 17beta-dihydroequilenine sodium sulfate, estrone sodium 3-sulfate, equilin 3 sodium sulfate, 17alpha-dihydroequiline 3-sodium sulfate, 3beta hydroxyster 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, sodium 17alpha-diol 3 -sulfate, 3beta-hydroxystr-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 and have the ability to behave as estrogen agonists, for example by lowering cholesterol and preventing bone loss., or as estrogen antagonists. Therefore, these compounds in the present formulations are useful for treating many discomforts 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 can 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. Bone loss can also be induced by medications such as that resulting from heparin treatments, alcohol consumption or the use of tobacco, barbiturates or corticosteroids. Drug-induced bone loss may also be the basis for treatment with gonadotropin-releasing hormone (GnRH or LHRH) or synthetic GnRH antagonists or agonists, such as injectable leuprolide acetate and sold TAP Pharmaceuticals Inc. by LUPRON "", or the goserelin acetate implant sold by Zeneca Pharmaceuticals under the trade name Zoladex "". Such bone loss can also result from the immobilization of chronic individual renal failure, malabsorption syndrome, liver disease, chronic obstructive pulmonary disease, rheumatoid arthritis or sarcoidosis. Additionally, these formulations can be used for hormone replacement therapy in postmenopausal women or in other estrogen deficiency states where estrogen supplementation may be beneficial. The symbiotic activity of the compounds and estrogen or oestrogens of the present methods of treatment are particularly of interest in resolving the undesired consequences of estrogen therapy, such as external bleeding and / or endometrial overstimulation, which can lead to endometrial hyperplasia or endometriosis. Therefore, these formulations can be used in methods to treat or prevent excessive uterine estrogen stimulation in a mammal. The formulations of this invention can also be used in methods of treatment for bone loss, which can result from an imbalance of the individual formation of new bone tissue and the resorption of older tissues, leading to a net loss of bone. Such bone reduction results in a range of individuals, particularly in postmenopausal women, who have experienced hysterectomy / oophorectomy, those who receive or who have received prolonged corticosteroid therapies, those who have experienced adrenal dysgenesis and those who suffer from Cushing's syndrome. Special needs for bone substitution can also be solved by using these formulations in individuals with bone fractures, defective bone structures and those receiving bone-related surgeries and / or prosthetic implantation. In addition to these problems described in the above, these formulations can be used in treatments for osteoarthritis, Paget's disease, osteomalasia, osteoalisteresis, endometrial cancer, multiple myeloma and other forms of cancer that have harmful effects on bone tissues. The methods for treating these diseases included in the above 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 the formulas (I) and (II) or a pharmaceutically acceptable salt of the same, along with a therapeutically desirable amount of an estrogen. This invention also includes pharmaceutical compositions using one or more of the present compounds and / or pharmaceutically acceptable salts thereof, together with one or more carriers, pharmaceutically acceptable excipients, etc. Estrogens regulate many physiological processes. The main target tissues for estrogens include the reproductive tract (ovary, uterus vagina), breast tissue, the skeletal and cardiovascular system as well as the central nervous system (CNS). The reduction in circulating estrogens produces numerous changes. There is a suspension of reproductive function with associated amenorrhea, uterine atrophy and increased vaginal dryness (lack of keratinization). The breast tissue becomes relatively quiescent. There is an increase in the rate of bone loss (2-7%) compared to the normal of 0.5-1.0% / year observed in all individuals over 35. A change in the lipid profile occurs which is increased in low density lipoprotein (LDL) and decreases in commonly measured high density lipoprotein (HDL) and an increased associated risk of a cardiovascular event (heart attack or attack). Changes in the central nervous system include an increase in vasomotor symptoms (flushing) and potential changes in learning 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 skeletal system (maintenance of bone mass, reduced risk of fractures). ) and the central nervous system (reduction in the frequency and severity of flushes). Although the reproductive tract He responds, not everything is positive. By the positive side, vaginal dryness is relieved. However, negative uterine responses include hypertrophy and hyperplasia along with some bleeding similar to menstrual bleeding. The breasts are also affected and there are data that correlate exogenous estrogen therapy with an increased risk of breast cancer. Currently, women with intact uteri are generally not prescribed estrogen alone, but estrogen in combination with a progestin to reduce uterine stimulation. Although the risks of endometrial cancer are reduced to treated levels without hormone, the other side effects of progestins reduce compliance in women on hormone replacement. The tissue selective estrogen (TSE) compounds of this invention provide skeletal and cardiovascular positive effects similar to those of estrogens, without the negative effects associated with the uterus and the breasts. The combinations of TSE and estrogen derive the positive effects of estrogen on the CNS, the bone system and the cardiovascular system with the combination that provides complementary or additive effects in the bone and cardiovascular systems. The main variable is the ability of TSEs to block the estrogenic influence in the uterus and breasts, which are the two main negative effects of non-opposite 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 discomfort and the individual being treated and will be submitted to the judgment of the practicing physician involved. It is preferred that the administration of one or more of the compounds herein begin at a low dose and increase until the desired effects are obtained. Similarly, it will be understood that the dosage or dosages of the estrogen or estrogens used in the present formulations will be selected according to conventional methods. It is further preferred that the dosage will be monitored to obtain the desired result with the minimum of estrogen or estrogen required. The effective administration of these compounds of formulas (I) and (II) can be provided at a dose of about 0.01 mg / day to about 1000 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.

Biological data Method 16 Stroke receptor binding test in vitro Preparation of the receiver CHO cells that overexpress the estrogen receptor are grown in 150 mm2 containers in DMEM + 10% dextran-coated activated charcoal, purified fetal bovine serum. The plates are washed twice with PBS and once with mM Tris-HCl, pH 7.4, 1 mM EDTA. The cells are harvested by scraping the surface after the cell suspension is placed on ice. The cells are broken with a portable motorized tissue grinder using two discharges of seconds. The crude preparation is centrifuged at 12,000 g for 20 minutes followed by centrifugation for 60 minutes at 100,000 g to produce a ribosome-free cytosol. The cytosol is then frozen and stored at -80 ° C. The protein concentration of the cytosol is estimated using the BCA assay with the standard reference protein.
Union test conditions The competition test was performed on 96-well plates (polystyrene *) which binds < 2.0% of [3H] -17β-estradiol introduced total, and each data point is recovered in triplicate. Aliquots of 100 μg / 100 μl of the receptor preparation are placed per well. A saturating dose of 2.5 nM [3H] 17ß-estradiol + competitor (or buffer) in a volume of 50 μl is added in the preliminary competition when evaluating competitors of lOOx and 500x, only [3H] 17β-estradiol 0.8 nM is used. . The plate is incubated at room temperature for 2.5 h. At the end of this incubation period, 150 μl of ice-cold dextran coated activated carbon (activated charcoal 5% coated with 69 K 0.05% dextran) are added to each well and the plate is immediately centrifuged at 99 g for 5 minutes at 4 ° C. Then 200 μl of the supernatant solution is removed by scintillation counting. Samples are subjected to 2% or 10 minutes, whichever comes first. Because polystyrene absorbs a small amount of [3 H] 17-estradiol, the wells contain radioactivity and cytosol, but are not processed with activated carbon and are included to quantify the amounts of available isotope. In addition, wells containing radioactivity but without cytosol are processed with activated carbon to estimate the non-removable MPE of [3H] 17β-estradiol. HE They used 96-well plates Corning No. 25880-96, because they have been shown to bind the least amount of estradiol.
Analysis of the results The radioactivity per minute (CPM) counts were automatically converted to decays per minute (DPM) by the Beckman LS 7500 scintillation counter using a set of cooled standards to generate an H No. for each sample. To calculate the% binding of estradiol in the presence of 100 or 500 times of competitor, the following formula was applied: ((Sample DPM-DPM not removed by activated carbon / (DPM of estradiol-DPM not removed by activated carbon)) x 100% =% estradiol binding For the generation of the IC50 curves, the union% versus compound% is plotted. IC50's are generated for compounds that show > 30% competition at a competitor concentration of 500x. For a description of these methods see Hulme, E.C., ed. 1992.

Five days before the start of each experiment (cell treatment) the medium is changed to phenol-free of DMEM / F12 + purified serum in activated charcoal coated with 10% dextran. On the day before treatment, cells are harvested using 0.5% trypsin / EDTA and plated at a density of 5 x 10 * cells / well in 96-well tissue culture plates. The test compounds are dosed at 10"s, 10" 7 and 10"8 M in addition to 10" 6 M (compound) + 10"'M 17β-estradiol to assess the ability of the compounds to function as antiestrogens. cells are treated for 48 h before the assay. Each 96-well plate contains a control of 17 β-estradiol. The same population for each dose is n = 8.
Alkaline phosphatase assay: At the end of 48 h, the medium is aspirated into the cells and washed three times with phosphate buffered saline (PBS). 50 μl of lysis buffer is added to each well (0.1 M Tris-HCl, pH 9.8, Triton X-100 0.2%). The plates are placed at -80 ° C for a minimum of 15 minutes. The plates are reheated to 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 dependent calculations are performed using the KineticCalc Application program (Bio-Tek Instruments, Inc., inooski, VT). The results are expressed as the mean +/- S.D. (standard deviation) of the enzyme reaction rate (slope) averaged over the line portion of the reaction kinetic curve (optical density readings every 5 minutes for 30 minutes of absorbance reading). The results for the compounds are summarized as percent of the response relative to 1 nM 17β-estradiol.

At the end of this incubation the precipitate is removed, the cells are washed with medium, fresh treatment medium is replaced and the cells are treated either with vehicle, 17μ-estradiol 1μM, 1μM compound or 1μM + 17β-estradiol compound 1 nM (tests for estrogen antagonism). Each treatment condition is performed in 8 wells (n = 8) which are incubated for 24 hours before the luciferase assay.
Luciferase assay After exposure for 24 h to the compounds, the medium is removed and each well is washed 2 X with 125 μl of PBS lacking Mg + * and Ca * +. After removing the PBS, 25 μl of Promega lysis buffer is added to each well and allowed to sit at room temperature for 15 min, followed by 15 min at -80 ° C and 15 min at 37 ° C. 20 μl of lysate is transferred to an opaque 96 well plate for evaluation of luciferase activity and 5 μl of remaining lysate is used for evaluation of B-galactosidase activity (transfection normalization). The luciferan substrate (Promega) is added in 100 μl aliquots to each well automatically by the luminometer and the light produced (relative light units) is read 10 seconds after the addition.

Then 50 μl of the Promega B-galactosidase 2X assay buffer is 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) is installed for each experimental run. The plates are analyzed in a Molecular Devices spectrophotometric plate reader at 410 nm. The optical densities for the unknown sample are converted to milliunits of activity by mathematical extrapolation from the standard curve.
Analysis of the results The luciferase data are generated as relative light units (RLU) accumulated during a 10 second measurement and are automatically transferred to a JPM file (SAS Inc) where the background RLUs are subtracted. The B-galactosidase values are automatically imported into the file and these values are divided among the RLUs to normalize the data. The mean and standard deviations are determined for n = 8 for every treatment The activity of the compounds is compared to 17β-estradiol for each plate. The percentage of activity compared to 17β-estradiol is calculated using the formula% = ((Estradiol-control) / (value of the compound) X 100. These techniques are described in Tzukerman, MT, Esty, A., Santiso-Mere, D., Danielian, P., Parker, MG, Stein, RB, Pike, JW and McDonnel, DP (1994) .The transactivational capacity of the human estrogen receptor was determined both in the cellular and promoter context and was mediated by two regions. functionally distinct intramolecular (see Molecular Endocrinology, 8: 21-30).

Black and R.L. Goode, Life Sciences, 26, 1453 (1980)). They are tested in groups of six immature Sprague-Dawley rats (females, 18 days old). The animals are treated by daily ip injection with 10 μg of compound, 100 μg of compound (100 μg of compound + 1 μg of 17β-estradiol) to verify antiestrogenicity and 1 μg of 17 β-estradiol, with 50% DMSO / solution 50% saline as an injection vehicle. On day 4, the animals are sacrificed by asphyxiation by C02 and their uteri are removed and cut to remove the excess lipid, any fluid is removed and the wet weight is determined. A small section of a horn is sent for histology and the rest is used to isolate total RNA in order to evaluate the complement component of expression 3.
Table 17 Uterine test in immature 3-day old rats Method No. 20 6-week ovariectomized rat model Female CD Sprague-Dawley rats, ovx or false ovx, are obtained 1 day after surgery of Taconic Farm (weight range 240-275 g). 3 or 4 rats / cage are housed in a room in a protocol of 14/10 (light / dark) and are provided with food (feed for rat purine 500) and with water ad libitum. Treatment for all studies begins 1 day after the animals arrive and are dosed 5 or 7 days per week, as indicated for 6 weeks. A matched group in age of rats operated on false does not receive any treatment and serve as a control group full of intact estrogen for each study. All treatments are prepared in 1% Tween 80 in normal saline at defined concentrations so that the volume of treatment is 0.1 ml / 100 g of body weight. 17β-estradiol is dissolved in corn oil (20 μg / ml) and is administered subcutaneously, 0.1 ml / rat. All dosages are adjusted at three-week intervals according to the mean body weight measurements of the group. Five weeks after the start of treatment and one week before the end of the study, each rat is evaluated to determine bone mineral density.
(BMD). The BMDs of the proximal tibia (PT) and the fourth lumbar vertebra (L4) in anesthetized rats are measured using a double-energy X-ray abscessiometer (Eclipse XR-26, Norland Corp. Ft. Atkins, Wl). Double-energy X-ray Absorptiometer (DXA) measurements for each rat are performed as follows: 15 minutes before the DXA measurements, the rats are anesthetized with an intraperitoneal injection of 100 mg / kg of ketamine (Bristol Laboratories, Syracuse , NY) and 0.75 mg / kg acepromazine (Aveco, Ft. Dodge, IA). The rat is placed on an acrylic plate under a DXA scanner perpendicular to its trajectory, the members are extended and fixed with paper tape to a surface of the plate. A preliminary scan is performed at a scanning speed of 50 mm / second with a scan resolution of 1.5 mm X 1.5 mm to determine the region of interest in PT and L4. Programming elements of small subjects are used at a scanning speed of 10 mm / second with a resolution of 0.5 mm X 0.5 mm for the final measurements of BMD. The programming elements allow the operator to define an area of 1.5 cm in width to cover the total length of L4. The BMDs for the respective sites are calculated by the programming elements as a function of the double beam attenuation (46.8 KeV and 80 KeV) of X-rays generated by the source below the subject and the detector moving along the area defined above the subject. The data ^^^^ - 20.8: -for BMD values (expressed in g / cm2) and individual scans are stored for statistical analysis. One week after the evaluation of BMD the rats are sacrificed by suffocation with carbon dioxide and the blood is collected for cholesterol determination. The uteri are removed and weighed. Total cholesterol is determined using the Boehringer-Mannheim Hitachi 911 clinical analyzer using the Cholesterol / HP equipment. The statistics are compared using the one-way analysis of variance with the Dunnet tests.
