The 17ß-cyano-18a-homo-19-nor-androst-4-ene derivatives of the present invention have gestagenic activity. They have the general chemical formula (1), in which Z is selected from the group comprising O, two hydrogen atoms, NOR and NNHSO2R, wherein R is hydrogen or C1-C4 alkyl, R4 is hydrogen or halogen and in addition either: R6a, R6b together form methylene or 1,2 ethanediyl or R6a is hydrogen and R6b is selected from the group comprising hydrogen, methyl and hydroxymethylene, and R7 is selected from the group comprising hydrogen, C1-C4 alkyl, C2-C3 alkenyl and cyclopropyl, or: R6a is hydrogen and R6b and R7 together either form methylene, or are omitted, whereby a double bond is formed between C6 and C7, R9 andR10 are hydrogen, or are omitted, whereby a double bond is formed between C9 and C10, R15 and R16 are hydrogen or together form methylene, R17 is selected from the group comprising hydrogen, C1-C4 alkyl and aIIyI, at least one of the substituents R4, R6a, R6b, R7, R15, R16 and R17 not being hydrogen, or R6b and R7 being omitted, whereby a double bond is formed between C6 and C7,or are omitted, whereby a double bond is formed between C1 and C2. The derivatives also comprise the solvates, hydrates, stereoisomers, diastereomers, enantiomers and salts of the aforementioned substances.

La présente invention concerne des dérivés de 17ß-cyano-18a-homo-19-nor-androst-4-ène présentant une activité gestagène, ainsi que certains de leurs solvates, hydrates, stéréoisomères, diastéréoisomères, énantiomères et sels. Ces dérivés sont représentés par la formule chimique générale (1). Dans cette formule, Z est choisi dans le groupe O, deux atomes d'hydrogène, NOR et NNHSO2R, R étant hydrogène ou C1-C4-alkyle. R4 est hydrogène ou halogène. En outre, on a soit d'une part R6a et R6b qui forment ensemble un méthylène ou un 1,2-éthanediyle (ou encore R6a qui est hydrogène alors que R6b est choisi dans le groupe hydrogène, méthyle et hydroxyméthylène) et R7 qui est choisi dans le groupe hydrogène, C1-C4-alkyle, C2-C3-alcényle et cyclopropyle, soit d'autre part R6a qui est hydrogène et R6b et R7 qui forment ensemble un méthylène (ou qui sont absents en cas de constitution d'une double liaison entre C6 et C7). R9 et R10 sont hydrogène ou sont absents en cas de formation de double liaison entre C9 et C10. R15 et R16 sont hydrogène ou forment ensemble un méthylène. R17 est choisi dans le groupe hydrogène, C1-C4-alkyle et allyle. L'un au moins des substituants R4, R6a, R6b, R7, R15, R16 et R17 est autre qu'hydrogène, ou bien R6b et R7 sont absents en cas de constitution d'une double liaison entre C6 et C7 ou entre C1 et C2.
