The invention relates to 17beta-allyloxy(thio)alkyl-androstane derivatives having general formula (I) wherein R1 is (H, OR), (H, OSO3H) or NOR; with R being H, (C1-6)alkyl or (C1-6)acyl; each of R2 and R3 is independently hydrogen or (C1-6)alkyl; n is 0, 1 or 2; X is O, S, S(O) or S(O)2; each of R4 and R5 is independently hydrogen or (C1-4)alkyl; each of R6, R7 and R8 is independently hydrogen, phenyl, halogen or (C1-4)alkyl, optionally substituted by hydroxy, (C1-4) alkoxy or halogen; or R7 and R8 together with the carbon atom to which they are bound form a (C3-6)cycloalkane ring; or R6 and R7 together with the carbon atoms to which they are bound form a (C5-6) cycloalkene ring; and wherein the dotted lines indicate a DELTA7 or a DELTA8 double bond, or a pair of conjugated double bonds selected from DELTA7,14, DELTA8,14 and DELTA6,8(14); or a pharmaceutically acceptable salt thereof. The compounds of the invention have meiosis activating activity and can be used for the control of fertility. |
