The invention relates to 17&bgr;-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 &Dgr;7 or a &Dgr;8 double bond, or a pair of conjugated double bonds selected from &Dgr;7,14, &Dgr;8,14 and &Dgr;6,8(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.
本发明涉及具有一般式(I)的17β-烯丙氧基(硫)烷基-雄烷衍生物,其中R1为(H,OR),(H,OSO3H)或NOR;R为H,(C1-6)烷基或(C1-6)酰基;R2和R3各自独立地为氢或(C1-6)烷基;n为0、1或2;X为O、S、S(O)或S(O)2;R4和R5各自独立地为氢或(C1-4)烷基;R6、R7和R8各自独立地为氢、苯基、卤素或(C1-4)烷基,可选择由羟基、(C1-4)烷氧基或卤素取代;或R7和R8与它们所连接的碳原子形成(C3-6)环烷基;或R6和R7与它们所连接的碳原子形成(C5-6)环烯基;其中虚线表示&Dgr;7或&Dgr;8双键,或从&Dgr;7,14、&Dgr;8,14和&Dgr;6,8(14)中选择的一对共轭双键;或其药学上可接受的盐。本发明的化合物具有减数分裂活性,可用于控制生育能力。
