The invention relates to 20-aralkyl-5&agr;-pregnane derivative having general formula (I), or a pharmaceutically acceptable salt thereof, wherein R1 is (H,OR), (H,OSO3H) or NOR; R is H, (C1-6)alkyl or (C1-6)acyl; each of R2 and R3 is independently hydrogen or (C1-6)alkyl; X is a straight chain divalent C1-8 hydrocarbon radical, optionally comprising a double or a triple bond; or X is —(CH2)m—CR7R8—; m=0-4; at least one of R7 and R8 is (C1-4)alkyl, hydroxy, (C1-4)alkoxy or halogen; the other, if present, being hydrogen; or R7 and R8 together represent O or NOR′; R′ is H, (C1-6)alkyl or (C1-6)acyl; each of R4, R5 and R6 is independently hydrogen, hydroxy, (C1-4)alkoxy, halogen, NR9, R10 or (C1-4)alkyl, optionally substituted by hydroxy, alkoxy, halogen or oxo; each of R9 and R10 is independently hydrogen or (C1-4)alkyl; and 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). The compounds of the invention have meiosis activating activity and can be used for the control of fertility.
该发明涉及具有通式(I)的20-芳基-5α-孕烷衍生物,或其药学上可接受的盐,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中的每一个独立地为氢或(C1-6)烷基;X为直链二价的C1-8碳氢基团,可选地包括双键或三键;或X为—(CH2)m—CR7R8—;m=0-4;R7和R8中的至少一个为(C1-4)烷基、羟基、(C1-4)烷氧基或卤素;另一个,如果存在的话,为氢;或R7和R8一起代表O或NOR′;R′为H、(C1-6)烷基或(C1-6)酰基;R4、R5和R6中的每一个独立地为氢、羟基、(C1-4)烷氧基、卤素、NR9、R10或(C1-4)烷基,可选地被羟基、烷氧基、卤素或氧代取代;R9和R10中的每一个独立地为氢或(C1-4)烷基;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。该发明的化合物具有激活减数分裂活性,可用于控制生育能力。
