In addition, this invention relates to these compounds of general formula I as well as their physiologically compatible addition salts with pharmaceutical preparations that contain organic and inorganic acids as well as their use for the production of pharmaceutical agents.
In the compounds of general formula I, the nitrogen atom in the side chain is preferably separated by 5 methylene groups from carbon atom 7 of the steroid skeleton.
If A stands for an alkyl group with up to 5 carbon atoms, this is a methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, pentyl, isopentyl, or neopentyl group; a methyl group is preferred as A.
Index n can assume the value 0, 1 or 2, whereby if A is a hydrogen atom or an alkyl group with up to 5 carbon atoms, value 1 is preferred for n, so that the nitrogen atom and the sulfur atom are separated by 3 methylene groups.

The nitrogen atom can be a component of a 4- to 7-membered or 5- to 7-membered heterocycle, which is substituted in 2- or 3-position with the radical of side chain -(CHz)n-SOx-(CH2)3-E.
Preferably, A and B together are a trimethylene group, i.e., together with the nitrogen atom and its adjacent carbon atom, they form a pyrrolidine ring that is substituted in 2-position.
In the latter case, value O is preferred for n and value O
is preferred for x.
The sulfur atom in the side chain can be present as a simple sulfur bridge (sulfide), as sulfone or sulfoxide. The sulfides are preferred.
As radical E, an unsubstituted ethyl radical or an ethyl radical that is fluorinated in one to five places is suitable;
the perfluorine radical is preferred for E.
If terminal substituent -(CH2)3-E in the side chain is replaced by an optionally substituted aryl or heteroaryl radical, which is bonded directly or via a mono-, di- or trimethylene group to the sulfur atom, the aryl radical is preferably a phenyl radical; in the case of a heteroaryl radical, this is preferably a 2-furyl or 2-thienyl radical. As a substituent to this aryl or heteroaryl radical, for example, this can be a pentafluoroethyl or trifluoromethyl group, preferably a trifluoromethyl group, and this in turn will preferably be in the 4-position of a phenyl radical. A 2-furyl or 2-thienyl radical is preferably separated from the sulfur atom by a methylene group.
Substituent R3 at the 3-oxygen atom is primarily a hydrogen atom. The hydroxy group can also, however, be etherified with a straight-chain or branched-chain, saturated or unsaturated hydrocarbon radical with up to 8 carbon atoms, such as, e.g., a methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, pentyl, isopentyl, neopentyl, heptyl, hexyl or octyl radical or esterified with an acyl radical R3--C(o)--~ in which R3 is a hydrogen atom or a hydrocarbon radical with up to 8 carbon atoms or a phenyl radical.
Substituents R11 can be a hydrogen atom, a halogen atom (F, Cl, Br, I) or a nitrooxy group; a fluorine atom is preferred.
If R11 stands for a hydrogen atom or if A and B together do not stand for - (CH2)p- or if A and D together do not stand for - (CH2)q-~ the D-ring exhibits a substitution from the group 14,15-double bond, 14~,15~-methylene, 15B-methyl, 15,15-dimethyl, 15~,16B-methylene, 16~- or 16~-halogen and of these especially 16~-fluorine, 16-methylidene or 14a,17a-ethano. A 15B-methyl group or 16~-fluorine atom preferably can be mentioned.
R17 can be in ~- or B-position.
In the case of a Cl5 alkyl group, this is a methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, pentyl, isopentyl or neopentyl group. As a C2s alkenyl group, for example, the vinyl or allyl radical can be mentioned. Typical representatives of a C25 alkinyl group are the ethinyl and 1-propinyl radicals.
If Rl7 is in a-position, especially a hydrogen atom, a methyl or trifluoromethyl group or an ethano bridge that is formed together with R14 stands for this.
For R17 in B-position, primarily a hydrogen atom and a methyl group can be mentioned.

Especially those compounds of general formula I are preferred in which side chain SK is either a radical of partial formula --(cH2)5--N(cH3)--(cH2)3--sox--(cH2)3 CzFs wi 2 or --(CH2)s--N(A)--(CHB)--CH2--S--(CH2)3--C2Fs with A + B =
--(CH2)3--. In the latter case, the compounds preferably exhibit a 17~-hydrogen atom.
Inorganic and organic acids, as they are known to one skilled in the art for forming physiologically compatible salts, are suitable for forming acid addition salts. As addition salts with acids, especially hydrochlorides and methanesulfonates can be mentioned.
The compounds below are especially preferred according to the invention:

The compounds according to the invention are, on the one hand, pure antiestrogens, or, on the other hand, so-called partial antagonists, i.e., antiestrogens with partial estrogenic action such as tamoxifen or raloxifen. The agonistic, estrogenic action is clearly less pronounced than in tamoxifen, however, in the compounds according to the invention in each case. Unlike tamoxifen, in the case of the partial antagonists of general formula I, their agonistic, estrogenic action occurs in a tissue-selective manner. The agonistic action especially occurs on bones, in the cardiovascular system and in the CNS (central nervous system). No agonistic action occurs especially on the uterus.
Compounds with antiestrogenic properties, i.e., substances with inhibiting actions relative to estrogens, have already been described extensively.
As the compounds that come closest structurally to the compounds in question here of general formula I, on the one hand, the steroid derivatives that are described in EP-A 0 138 504 can be considered, and of the latter especially 7~-[9-(4,4,5,5,5-pentafluoropentylsulfinyl)-n-nonyl~-estra-1,3,5(10)-triene-3,17~-diol (EP-A 0 138 504, page 58, penultimate compound). This compound is currently under clinical development for hormone-dependent tumors (breast cancer) and represents the compound that is best known at this time, i.e., the one with the strongest antiestrogenic activity, of these steroid derivatives.
Pharmaceutical compositions that contain sex steroid inhibitors and exhibit a steroidal skeleton, which exhibits a 7~-side chain with the simultaneous presence of at least one other substituent in 14-, 15- or 16-position, are the subject of EP-A 0 376 576 and are also to be considered as the closest prior art.
A considerable number of the most varied compounds -- i.a., those of steroidal origin and those with a 2-phenylindole skeleton -- which act as antiestrogens and/or suppress the estrogen biosynthesis, are disclosed in W0 93/10741.

CA 02263708 l999-02-l9 ~ 13 Other steroidal antiestrogens are described in EP-AS 0 384 842 and O 629 635, which have an 11~-phenyl radical.
In the compounds according to the invention, there are antiestrogens with stronger antiestrogenic action than the already mentioned 7~-[9-(4,4,5,5,5-pentafluoropentylsulfinyl)-n-nonyl]-estra-1,3,5(10)-triene-3,17~-diol.
The compounds of general formula I according to this application are distinguished in comparison to the already known steroid derivatives according to EP-A O 138 504 and EP-A 0 367 576 by novel side chains on carbon atom 7 of the steroid skeleton. This structural modification results in especially greatly antiestrogenically active compounds, as was demonstrated in a transactivation test.
In addition, relative to the compounds of EP-A O 138 504, the compounds of general formula I are distinguished with respect to the substitution on carbon atom 11 and/or of the D-ring (except in the case that A and B together stand for - (CH2)p- or A and D together stand for - (CH2)q ). In comparison to the compounds of EP-A 0 367 576, the compounds of general formula I
on carbon atom 11 and/or in the D ring can carry the same or other substituents.
By the disclaimer in the definition of general formula I, compounds that are described from their scope in non-prepublished DE P 196 22 457 are excluded.
The antiestrogenic action of the compounds according to the invention was determined in transactivation assays [Demirpence, E.; Duchesne, M.-J.; Badia, E.; Gagne, D. and Pons, M.: MVLN

The HeLa cells are transiently transfixed with human estrogen receptor-expression vector (HEGO) and Vit-TK-CAT
reporter genes, and the MVLN cells are transfixed in a stable manner with reporter gene Vit-TK-LUC. The estrogenic active strength was determined in the presence of 0.1 Nm of estradiol.
The ICso values for the new compounds lie in the nanomolar range. In the HeLa cell line as well as the MVLN cell line, the following IC50 values are produced for the compounds of Examples 12, 15, 18, 25, 29, 31 and 36 as well as for 7~-[9-(4,4,5,5,5-pentafluoropentylsulfinyl)-n-nonyl]-estra-1,3,5(10)-triene-3,17B-diol (execution of test according to the above-indicated CA 02263708 l999-02-l9 bibliographic references):

The tests that are described below were performed:
1. Uterus growth test in infantile rats, p.o. (test for antiestrogenic action) 2. Tumor test: Antitumor action on the hormone-dependent breast cancer DMBA+-induced breast cancer in rats ~ - dimethylbenzanthracene 1. Uterus growth test in infantile rats (Antiestrogenic action) CA 02263708 l999-02-l9 Principle of the Method In rodents, the uterus reacts to the administration of estrogens with a weight increase (both proliferation and water retention). This growth can be inhibited, depending on the dose, by simultaneous administration of compounds that have an antiestrogenic action.

Execution of the Test Animals:
Infantile, female rats that weigh 35-45 g at the beginning of the test, 5-6 animals per dose.

Formulation and Administration of the Substances:
For p.o. administration, the substances are dissolved in 1 part ethanol (E) and made up with 9 parts peanut oil (EO).

Test Preparation The young rats just dropped by the mothers are delivered for acclimation one day before the beginning of treatment and immediately supplied with food -- right in the cage. The treatment then is carried out once daily over 3 days in combination with 0.5 ~g of estradiolbenzoate (EB). EB is always administered subcutaneously (s.c.), while the test substance is administered p.o. (perorally). Twenty-four hours after the last administration, the animals are weighed, sacrificed, and the uteri are removed. The moist weights (less contents) are determined from the prepared uteri.

CA 02263708 l999-02-l9 Controls Negative control: vehicle (E/EO), 0.2 ml/animal/day Positive control: 0.5 ~g of EB/0.1 ml/animal/day Evaluation From the relative organ weights (mg/100 g of body weight), the average values with standard deviation (X + SD), and the significance of the differences to control group (EB) in the Dunnett test (p < 0.05) are determined for each group. The calculation of inhibition (in %) compared to the EB control is carried out with a program. The relative actions of the test substances are determined by co-variance and regression analysis.

The compounds according to the invention are distinguished by a better bio-availability after oral administration.

2. Tumor Test Influencing the Tumor Growth in the DMBA Model in Rats ~ DMBA Tumor Model) 9,10-Dimethyl-1,2-benzanthracene Biological Basis The growth of the DMBA-induced breast neoplasm in rats is largely dependent on estrogens and prolactin. Active antiestrogens, antigestagens and aromatase inhibitors result in inhibiting tumor growth. Substances that have antigonadotrophic and androgenic properties also exert a tumor-inhibiting action.

Animal 8ubjects 45-47-day-old female rats (Sprague-Dawley, ZIH or Mollegard strains), 8-10 animals per group.

Test PreParation The animals receive 10 mg of DMBA orally on a one-time basis. Then, the animals are checked once a week by palpation for tumor development. Six to ten weeks after the DMBA
treatment, about 1 to 10 tumors develop per animal. The tumor size is determined once weekly with the aid of a sliding gauge.

If at least one tumor has reached a defined size (150 mm2 of tumor surface area), the ovariectomy of the animals is carried out or the treatment of the animals with the test substance begins. In most cases, the treatment is carried out daily over about 28 days (for details of the procedure, see Test Plan). In addition, the tumor size is determined once a week.

Evaluation The total tumor size per animal is determined before the beginning of the treatment (previous values). For each group, the mean of the percentage changes in tumor size, relative to the starting values, is then calculated. In addition, the percentage of animals per group is determined whose tumors in each case (1) have totally regressed (total regression), have partially regressed (partial regression), (3) are unchanged (no change) or (4) have further progressed (increase).
The values that are determined are tested for significance in the Dunnett Test and are depicted graphically.

Test Result At an oral dose of 3 mg/kg/day, llB-fluoro-7~-{5-[2-(4,4,5,5,5-pentafluoropentylthiomethyl~-pyrrolidin-1-yl]-pentyl}-estra-1,3,5(10)-triene-3,17~-diol (compound of Example 29) inhibits the tumor growth more greatly than an oral dose of 10 mg/kg/day of 7~-[9-(4,4,5,5,5-pentafluoropentanesulfinyl)-nonyl]-estra-1,3,5(10)-triene-3,17~-diol, which at this dose exerts only a slight action in comparison to the intact control. An ovariectomy results in a total remission of tumors (Figure 1).
The compounds have an inhibiting action on the growth of hormone-dependent tumor cells; they especially inhibit the growth of estrogen-dependent human breast neoplasm cells (MCF-7).
The antiproliferative activity of the new compounds in breast neoplasm cell lines is greater than that of 7~-[9-4,4,5,5,5-pentafluoropentylsulfinyl)-n-nonyl]-estra-1,3,5(10)-triene-3,17~-diol.
As pure antiestrogens for the purposes of this invention, those compounds of general formula I can be considered that show no agonistic action or only a slight agonistic action in the in-vitro test on estrogenic action below (up to about 10% of the action of estradiol).
In this case, the partial estrogenic action was also determined by transactivation assays. HeLa cells were transfixed with human estrogen receptor-expression vector (HEG0) and a reporter gene rPR-TK-CAT. This reporter gene contains the "estrogen responsive element" of the rabbit progesterone receptor gene (+698/+729 region) before a TK-CAT gene (Savouret, J. F.;
Bailly, A.; Misrahi, M.; Rauch, C.; Redeuilh, G.; Chauchereau, A.; Milgrom, E.: Characterization of the Hormone Responsive Element that is Involved in the Regulation of the Progesterone Receptor Gene. EMBO J. 10, 1875-1883 (1991).
The estrogenic active strength was determined at a concentration of 1 ~M.

Reference ZM 182780 -15 A negative value means suppression of the reporter gene activity below the values of the controls.
The compounds according to the invention, especially if they are pure antiestrogens, are suitable for treatment of estrogen-dependent diseases, for example, breast cancer (second-line treatment of tamoxifen-resistant breast cancer; for adjuvant treatment of the breast cancer instead of tamoxifen), endometrial carcinoma, prostatic hyperplasia, anovulatory infertility and melanoma.
In addition, the pure antiestrogens of general formula I can be used as components in the products that are described in EP
346 014 B1 and that contain an estrogen and a pure antiestrogen, namely for simultaneous, sequential or separate use for the selective estrogen therapy of peri- or postmenopausal women. The compounds of general formula I, especially if these are pure antiestrogens, can be used together with antigestagens (competitive progesterone antagonists) for the treatment of hormone-dependent tumors (EP 310 542 A).
Other indications, in which the compounds of the general formula can be used, are male hair loss, diffuse alopecia, alopecia that is caused by chemotherapy and hirsutism (Hye-Sun Oh and Robert C. Smart. Proc. Natl. Acad. Sci. USA, 93 (1996) 12525-12530).
In addition, the compounds of general formula I can be used for the production of medications for the treatment of endometriosis and endometrial carcinomas.
The compounds of general formula I can also be used for the production of pharmaceutical compositions for male and female birth control (male birth control: DE-A 195 10 862.0).
The compounds of general formula I with tissue-selective partial estrogenic action primarily can be used for prophylaxis and treatment of osteoporosis and for the production of preparations for substitution therapy in pre-, peri- and post-menopause (HRT) (Black, L. J.; Sato, M.; Rowley, E. R.; Magee, D.
E.; Bekele, A.; Williams, D. C.; Cullinan, G. J.; Bendele, R.;
Kauffman, R. F.; Bensch, W. R.; Frolik, C. A.; Termine, J. D. and Bryant, H. U.: Raloxifene [LY 139481 HCl] Prevents Bone Loss and Reduces Serum Cholesterol without Causing Uterine Hypertrophy in Ovariectomized Rats; J. Clin. Invest. 93: 63-69, 1994). The CA 02263708 l999-02-l9 partial estrogenic action occurs only on the desired target organ.
The invention also relates to pharmaceutical preparations that contain at least one compound of general formula I (or physiologically compatible addition salts with organic and inorganic acids of them), and the use of these compounds for the production of pharmaceutical agents, especially for treating estrogen-dependent diseases and tumors and pharmaceutical agents for hormone replacement treatment (HRT).
The compounds according to the invention and the acid addition salts are suitable for the production of pharmaceutical compositions and preparations. The pharmaceutical compositions or pharmaceutical agents contain as active ingredient one or more of the compounds according to the invention or their acid addition salts, optionally in a mixture with other pharmacologically or pharmaceutically active substances. The production of the pharmaceutical agents is carried out in a known way, whereby the known and commonly used pharmaceutical adjuvants as well as other commonly used vehicles and diluents can be used.
As such vehicles and adjuvants, for example, those are suitable which are recommended or indicated in the following bibliographic references as adjuvants for pharmaceutics, cosmetics and related fields: Ullmans Encyklopadie der technischen Chemie [Ullman's Encyclopedia of Technical Chemistry], Volume 4 (1953), pp. 1 to 39; Journal of Pharmaceutical Sciences, Volume 52 (1963), pp. 918 and ff.; H. v.

The compounds can be administered orally or parenterally, for example, intraperitoneally, intramuscularly, subcutaneously or percutaneously. The compounds can also be implanted in tissue. The amount of the compounds to be administered varies within a wide range and can cover any effective amount.
Depending on the condition to be treated and the type of administration, the amount of administered compound is 0.1-25 mg/kg of body weight, preferably 0.5-5 mg/kg of body weight, per day. In humans, this corresponds to a daily dose of 5 to 1250 mg.
The preferred daily dosage in humans is 50 to 200 mg. This holds true especially for tumor therapy.
For oral administration, capsules, pills, tablets, coated tablets, etc., are suitable. In addition to the active ingredient, the dosage units can contain a pharmaceutically compatible vehicle, such as, for example, starch, sugar, sorbitol, gelatin, lubricant, silicic acid, talc, etc. The individual dosage units for oral administration can contain, for example, 5 to 500 mg of active ingredient.
To achieve a better bio-availability of the active ingredient, the compounds can also be formulated as cyclodextrin clathrates. In this connection, the compounds with ~-, B- or y-cyclodextrin or their derivatives are reacted (PCT/EP95/02656).
For parenteral administration, the active ingredients can be dissolved or suspended in a physiologically compatible diluent.
As a diluent, very frequently oils with or without the addition of a solubilizer, a surfactant, a suspending agent or emulsifier are used. Examples of oils that are used are olive oil, peanut oil, cottonseed oil, soybean oil, castor oil and sesame oil.
The compounds can also be used in the form of a depot injection or an implant preparation, which can be formulated so that a delayed release of active ingredient is made possible.
Implants can contain, as inert materials, for example, biodegradable polymers or synthetic silicones, such as, for example, silicone rubber. In addition, the active ingredients can be added to, for example, a patch, for percutaneous administration.
The compounds according to the invention can be produced as described below. The following examples are used for a more detailed explanation of the invention. By an analogous approach using reagents like those in the data that are contained in the examples, all compounds of general formula I can be obtained.
The saponification of the ester groupings as well as esterification and etherification of free hydrogen groups is carried out in each case according to established processes of organic chemistry. By observing the differing reactivity of the esterified and free 3- and 17-hydroxy groups, the 3,17-diesters can be cleaved selectively in 3-position, and the 3-hydroxy-17-acyloxy compound can then be additionally functionalized specifically in the 3-position; it is equally possible to esterify or to etherify the 3,17-dihydroxy compound selectively only in the 3-position and then to introduce specifically another radical into the 17-position as already in the 3-position.
The acid addition salts of the compounds of general formula I can also be produced according to standard processes from the compounds of general formula I.
