A series of novel D-ring modified derivatives of estrone was synthesized and tested as inhibitors of steroid sulfatase (STS). The steroidal D-ring was cleaved via an iodoform reaction and thermal condensation of the resulting marrianolic acid derivative gave 16,17-seco-estra-1,3,5(10)-triene-16,17-imide derivatives, where a piperidinedione moiety is in place of the D-ring. This synthetic approach was
合成了一系列新的雌酮的D环修饰的衍生物,并作为甾族硫酸酯酶(STS)的抑制剂进行了测试。通过碘仿反应裂解甾族D-环,然后热缩合所得马来酸衍生物,得到16,17-seco-estra-1,3,5(10)-三烯-16,17-酰亚胺衍生物,其中哌啶二酮部分代替D环。发现该合成方法比贝克曼重排的文献方法具有更高的总产率。在亚氨基环的氮原子上引入了一系列烷基侧链,并合成了相应的3-O-氨基磺酸盐。当在胎盘微粒体中对STS进行抑制测试时,带有丙基(39)和1-吡啶-3-基甲基(46)部分的新D环修饰的雌酮衍生物的IC(50)值为1 nM。
