was investigated. Compounds 6 and 7, which have a carboxylic acid at the end of the side chain at the position 7alpha of dihydrotestosterone (DHT), showed partial agonistic activities in reporter gene assay (RGA). Conversion of the steroidal core structure to 17alpha-methyltestosterone gave compound 14, which showed weak pure antagonistic activity. Optimization of the side chain by the insertion of
研究了CH4892280(4)(一种雄激素受体(AR)纯拮抗剂)的前导优化。在二氢睾酮(DHT)7α位的侧链末端具有羧酸的化合物6和7在报告基因测定(RGA)中显示出部分激动活性。甾体核心结构向17α-甲基睾丸酮的转化得到化合物14,其显示出弱的纯拮抗活性。通过插入苯环优化侧链产生化合物22和28-30,其在亚微摩尔浓度下显示出纯的拮抗活性。阐明了结构-活性关系。
