The invention concerns a 3-methylene steroid derivative having general formula (1) wherein R1 is H or together with R3 forms a &bgr;-epoxide or R1 is absent if there is a 5-10 or 4-5 double bond; R2 is (C1-C5) alkyl or CF3; R3 is &bgr;H, &bgr;CH3 or together with R1 forms a &bgr;-epoxide or R3 is absent if there is a 5-10 double bond; R4 is H, lower alkyl; Y is [H, H], [OH, H], ═O, [OH, lower alkyl], [OH, (C2-C5)alkenyl], [OH, (C2-C5)alkynyl] or (C1-C6) alkylidene, whereby said alkyl, alkenyl, alkynyl and alkylidene is optionally halogenated; ═NOR5, whereby R5 is H, lower alkyl; dotted lines represent an optional double bond, or prodrugs thereof for the treatment of arthritic diseases and/or autoimmune diseases.
该发明涉及具有一般式(1)的3-亚甲基类固醇衍生物,其中R1为H或与R3一起形成β-环氧化物,或者如果存在5-10或4-5双键,则R1不存在;R2为(C1-C5)烷基或CF3;R3为βH,βCH3或与R1一起形成β-环氧化物,或者如果存在5-10双键,则R3不存在;R4为H,低烷基;Y为[H,H],[OH,H],HO,[OH,低烷基],[OH,(C2-C5)烯基],[OH,(C2-C5)炔基]或(C1-C6)烷基亚甲基,其中所述烷基,烯基,炔基和烷基亚甲基可选择卤代;NOR5,其中R5为H,低烷基;虚线代表可选的双键,或其前药,用于治疗关节炎和/或自身免疫疾病。
