The invention relates to new C-19-halogen-substituted steroids of the androst-9(11)-ene series, namely 17&bgr;-hydroxy-19-halogen-androsta-4,9(11)-dien-3-ones of general formula (I) and process for their production. In addition, the use of new radiohalogen-labeled compounds of Formula (I) as radiopharmeceutical agents is the subject of the invention as well as the use of non-labeled compounds of Formula (I) as starting products for the production of new biologically active 5&bgr;-substituted androst-9(11)-enes of general formula (II) and the new 6&bgr;,19-cycloandrostadienes of Formula (III) as well as processes for their production and their use.
                            该发明涉及一种新的C-19卤代类
固醇,属于雄甾-9(11)-烯系列,即17β-羟基-19卤代雄甾-4,9(11)-二烯-3-酮的一般式(I)及其生产方法。此外,新的Formula (I)放射性卤代化合物作为放射性药用剂的使用也是本发明的内容,以及Formula (I)非标记化合物作为生产新的
生物活性5β-取代雄甾-9(11)-烯的起始物质,其一般式为(II),以及新的6β,19-环雄烯的Formula (III)的生产过程和使用。
