<p>The 17Ã-cyano-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, R<sup>4</sup> is hydrogen or halogen and in addition either: R<sup>6a</sup>, R<sup>6b</sup> together form methylene or 1,2 ethanediyl or R<sup>6a</sup> is hydrogen and R<sup>6b</sup> is selected from the group comprising hydrogen, methyl and hydroxymethylene, and R<sup>7</sup> is selected from the group comprising hydrogen, C1-C4 alkyl, C2-C3 alkenyl and cyclopropyl, or: R<sup>6a</sup> is hydrogen and R<sup>6b</sup> and <sup>R7</sup> together form methylene, or are omitted, whereby a double bond is formed between C<sup>6</sup> and C<sup>7</sup>, R<sup>9</sup> and R<sup>10</sup> are hydrogen, or are omitted, whereby a double bond is formed between C<sup>9</sup> and C<sup>10</sup>, R<sup>15</sup> and R<sup>16</sup> are hydrogen or together form methylene, R<sup>17</sup> is selected from the group comprising hydrogen, C1-C4 alkyl and aIIyI, at least one of the substituents R<sup>4</sup>, R<sup>6a</sup>, R<sup>6b</sup>, R<sup>7</sup>, R<sup>15</sup>, R<sup>16</sup> and R<sup>17</sup> not being hydrogen, or R<sup>6b</sup> and R<sup>7</sup> being omitted, whereby a double bond is formed between C<sup>6</sup> and C<sup>7</sup>. The derivatives also comprise the solvates, hydrates, stereoisomers, diastereomers, enantiomers and salts of the aforementioned substances.</p> |
