Abstract
The compoundns can be applied for the preparation ofmedicamentous forms designed for tumour and hormonal therapy. Theyshow very strong antistrogenous effect. Part of them are pureantiestrogens, and another part have partial estrogenous effect.The substituted 7-( -aminoalkyl)-estratrines have the formulawhere the side chain SK means a residue with the formula- -(CH2)m- -N- -CH- -(CH2)n--(CH2)3--EA B Dwhere m has the value of 4, 5 or 6, n - 0, 1 or 2, x - 0, 1 or 2,A means hydrogen atom or C1-5-alkyl group, B and D are always ahydrogen atom, or C1-5-alkyl group, B & D are always a hydrogenatom, or A & B together mean alkylene group --(CH2)p--c, p iw 2,34or 5 and D is hydrogen atom, or A & D together mean alkylene group-(CH2)q-- c, q is 2, 3 or 4 and B means hydrogen atom and E isunsubstituted or one or five times fluorinated ethyl residue, orthe end substitutent --(CH2)-2-E-- of the side chain is optionallysubstituted by a substituted aryl and heteroaryl residue which isbound directly or by means of mono- di- or trimethylene group tothe sulphur atom, R3 means hydrogen atom, carbon residue with upto 8 carbon atoms or residue with the formulaR3'-C(O)-,where R3' is hydrogen or carbon atom with up to 8 carbon atoms oris phenyl residue, R11 is hydrogen, halogen atom or onenitrooxygroup -O-NO2, R14, R15, R16 & R16 always mean hydrgoenatom or R14 & R15 mean additional bond or methylene bridge, or R15means methylene group and R15 means hydrogen atom, or R15 & R15are alway a methylene group, or R15 and R16 together formmethylene bridge, or R16 or R16 means halgen atom or R16 togethermean methylidene group and the customary substitutents R14m R15,R15, R16 and R16 are always hydrogen atom, R17' means hydrogenatom in - or - position means C1-5-alkyl, C2-5-alkylene orC2-5-alkynyl group or is trifluoromethyl group and R17" ishydrogen atom or residue with formulaR17''' --C(O)--in which R17''' is hydrogen atom or carbon residue with up to 8carbon atoms, or when R17' is in - position, R17', together withR14 form ethanol bridge provided that A & B simultaneously do notmean -(CH2)p or A & D togehter do not mean -(CH2)q, at least onesubstituent of R11, R14, R15, R16 & R16 is not a hydrogen atom.The invention also relates to the physiologically aceptableadjunctive salts of the compounds with organic and inorganicacids.42 claims
