Definitions
- the present invention relates to new 11 ⁇ -long-chain-substituted 19-nor-17 ⁇ - 5 pregna-1, 3,5 (10) -triene-17ß-ols with a 21, 16-lactone ring, processes for their preparation and pharmaceuticals containing these compounds Preparations and the use of these compounds for the manufacture of medicinal products.
- Estrogens exert their physiological effect via receptor proteins, the estrogen receptors (ERs). These are core transcription factors that can be activated by ligands. Until a few years ago, estrogens were thought to exert their effect through a single receptor.
- ERß estrogen receptor 5
- ERß predominates over ER ⁇ in the rat prostate
- ER ⁇ predominates in the rat uterus.
- Areas were identified in the brain in which only one of the two ER subtypes is expressed (Shugrue et al., Steroids 61, 1996, 678-0681; Li et al., Neuroendocrinology 66, 1997, 63-67).
- ERß knockout mice In malignant degenerate breast tissue, upregulation of ER ⁇ expression and reduced ERß expression were observed in several independent studies (Leygue et al., Cancer Res. 58, 1998, 3197-3201; Iwao et al., Int. J. Cancer 88, 2000 , 733-736; Lacennec et al., Endocrinology 142, 2001, 4120-4130; 0 Roger et al., Cancer Res. 61, 2001, 2537-2541).
- ERß knockout mice missing ERß have abnormal epithelial growth of the breast and overexpression of the proliferation marker Ki67 (Gustafsson and Warner, 2000).
- ERß also acts as an inhibitor of ER ⁇ transcriptional activity and lowers cellular responsiveness to estradiol (Hall and McDonnell, Endocrinology 140, 1999, 5566-5578). These data support the hypothesis that ERß is, among other things, a protective factor against the mitogenic activity of estrogens mediated by ER ⁇ . ERß can therefore be seen as an endogenous opponent of ER ⁇ .
- WO 01/00652 discloses 11 ⁇ -long-chain-substituted estratrienes of the general formula I,
- R11 is a long-chain radical which has a nitrogen atom and, if appropriate, a sulfur atom and which can also be terminally functionalized with a perfluoroalkyl group or an optionally substituted aryl radical.
- the compounds have antiestrogenic or tissue-selective estrogenic properties and are suitable for the production of medicaments.
- the object of the present invention is to provide new compounds which have a dissociation in vitro with regard to their binding to estrogen receptor preparations from rat prostate and rat uterus, and in vivo via the preferential antagonization of ER ⁇ without stopping the positive properties of ERß antiproliferative effect. This closes also a preferential suppression of the expression of ER ⁇ without reducing the ERß expression.
- R 33 is a hydrogen atom, a C 1- alkyl, C 2 . 6 -acyl or tri (C -4 -4 -alkyl) silyl group or a group R 18 SO 2 -, where R 18 is a group R 19 R 20 N-, where R 19 and R 20 independently of one another are a hydrogen atom, a C 1- 5 -alkyl radical, a group C (O) R 21 and wherein
- R 21 is a straight-chain or branched hydrocarbon radical having up to 12 carbon atoms, which can also contain up to three double bonds, a C 3-7 cycloalkyl radical, an aryl radical which may be substituted, an aralkyl or an alkylaryl radical, and
- R 11 is a radical of the formula -BZR 22 , where B is a straight-chain or branched-chain alkylene having 4 to 9
- R 13 represents a methyl or ethyl group.
- the present invention further relates to medicaments which contain a compound of the general formula II or its pharmaceutically acceptable addition salts with organic or inorganic acids.
- an aryl radical which may optionally be substituted, is a phenyl, 1- or 2-naphthyl radical, the phenyl radical being preferred. If not expressly mentioned, aryl always includes a heteroaryl radical. Examples of a heteroaryl radical are the 2-, 3- or 4-pyridinyl, the 2- or 3-furyl, the 2- or 3-thienyl, the 2- or 3-pyrrolyl, the 2-, 4- or 5 -lmidazolyl-, the pyrazinyl, the 2-, 4- or 5-pyrimidinyl or 3- or 4-pyridazinyl radical.
- substituents for an aryl, heteroaryl or aralkyl radical are methyl, ethyl, trifluoromethyl, pentafluoroethyl, trifluoromethylthio, methoxy, ethoxy, nitro, cyano, halogen (fluorine, chlorine, bromine, iodine) ), hydroxy, amino, mono (C- ⁇ -8 - alkyl) - or di (C 1-8 alkyl) amino, whereby both alkyl groups are identical or different, di (aralkyl) amino, whereby both aralkyl groups are identical or are different.
- alkyl radicals or straight or branched chain alkyl groups with up to 12 carbon atoms in the sense of R 3 , R 19 and R 20 or R 21 are, for example, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, To name pentyl, isopentyl, neopentyl, hexyl, heptyl, decyl. Methyl, ethyl, propyl and isopropyl are preferred.
- Alkylene, alkenylene or alkinylene radicals in the range from 3 to 11 carbon atoms in the sense of B or R22 include, for example, propylene, butylene, isobutylene, pentylene, methylbutylene, hexylene, heptylene, octylene or butenylene, 2-butenylene, 3-butenylene, 1-ethyl-ethenylene, 2-ethyl-ethenylene, 1-methyl (1-propenylene), 1-methyl (2-propenylene), 2, 3-dimethyl-1-butenylene, 2,3-dimethyl-2- butenylene, 3-dimethyl-1-butenylene, 2-methyl-2-butenylene, hexenylene, 4-methyl-1-pentenylene, heptenylene, 1-octenylene, trans-2-octenylene or 1-butynylene, 2-butynylene, 3 - Butynylene, 3-methyl (1-but
- the alkyl groups can be partially or completely substituted by 1-5 halogen atoms, for example fluorine atoms.
- Trifluoromethyl and pentafluoroethyl may be mentioned as perfluorinated alkyl groups.
- Representatives of the partially fluorinated alkyl groups are, for example, 2,2,2-trifluoroethyl, 5,5,5,4,4-pentafluoropentyl, etc.
- C 2-6 acyl radicals mean, for example, acetyl, propionyl, butyryl, valeroyl, isovaleroyl, pivaloyl, hexanoyl.
- C 3 -cycloalkyl group can be, for example, cyclopropyl, cyclobutyl, cyclopentyi, cyclohexyl.
- the hydroxyl group on the C atom 3 can be esterified with an aliphatic, straight or branched chain, saturated or unsaturated C 26 carboxylic acid.
- suitable carboxylic acids for esterification are: acetic acid, propionic acid, butyric acid, isobutyric acid, valeric acid, isovaieric acid or pivalic acid.
- Examples of a tri (C 1-4 alkyl) group include a trimethylsilyl group and a tert-butyldimethyl group.
- R 3 represents a hydrogen atom or a methyl group and R 13 represents a methyl group and R 11 can be selected from the group of the following side chains - (CH 2 ) 5 N (CH 3 ) (CH 2 ) 3 C 2 F 5
- inorganic acids include hydrochloric acid, hydrobromic acid, sulfuric acid and phosphoric acid
