Described are steroidal C-17 benzoazoles, pyrimidinoazoles (azabenzoazoles) and diazines. Methods for their synthesis are also described, which include methods having a step of nucleophilic vinylic “addition-elimination” substitution reaction of 3β-acetoxy-17-chloro-16-formylandrosta-5,16-diene or analogs thereof and benzoazole or pyrimidinoazole nucleophiles and methods having a palladium catalyzed cross-coupling reaction of 17-iodoandrosta-5,16-dien-3β-ol or analogs thereof with tributylstannyl diazines. The compounds are potent inhibitors of human CYP 17 enzyme as well as potent antagonists of both wild type and mutant androgen receptors (AR). The compounds are useful for the treatment of human prostate cancer.
描述了类
固醇C-17苯并咫唑、
嘧啶咪唑咪唑(氮杂苯并咫唑)和二氮杂
苯并咪唑。还描述了它们的合成方法,其中包括3β-乙酰氧基-17-
氯-16-甲酰基雄甾-5,16-二烯或其类似物和苯并咫唑或
嘧啶咪唑亲核试剂的亲核
乙烯“加成-消除”取代反应步骤的方法,以及17-
碘雄甾-5,16-二烯-3β-醇或其类似物与三
丁基锡二氮杂苯基的
钯催化交叉偶联反应的方法。这些化合物是人类CYP 17酶的有效
抑制剂,同时也是野生型和突变雄激素受体(AR)的有效拮抗剂。这些化合物对于治疗人类前列腺癌是有用的。
