摘要:

设计和合成了一些4'-5'-取代的17-(2'-噁唑基)-雄甾-5,16-二烯衍生物作为_17α-羟化酶/C17,20-裂解酶(P45017α) 的抑制剂,用以治疗前列腺癌。药理筛选结果表明,化合物6c,17-(2'-噁唑基)-雄甾-5,16-二烯-3-醇为强的抑制剂,其活性可与欲进入临床I 期的标准对VN85相当。在噁唑基4' 5'位上甲基或苯基基团的引入降低了生物活性。如预期所料,3-醋酸酯5ac8的体外活性要弱于其相应的3-羟基物6a~c 9。化合物6c 的深入药理实验在进行中。

Abstract:

Several 4'- and 5'-substituted 17-(2'-oxazolyl)-androsta-5,16-diene derivatives were designed and synthesized as inhibitors of 17α-hydroxylase/C17,20-Lyase (P45017α) for the treatment of prostatic cancer, the results of the preliminary pharmacological screening showed that compound 6c, i.e. 17-(2'-oxazoly)-androsta-5,16-diene-3-ol was a strong inhibitor, comparable with that of the reference compound VN-85. The introduction of methyl or phenyl group at the 4' or 5' position of oxazole ring decreased the activity. The in vitro activities of 3-acetate 5a~c and 8 were lower than their 3-ol counterparts 6ac and 9 as expected. The further pharmacological study of 6c is in progress.

Key words: 17-Oxazolyl androstene, P45017α Inhibitors, Prostate cancer, Bioisosterism
