drug target for management of hormone-dependent malignancies. In the present study, a new series of twenty-one aryl amido-linked sulfamate derivatives 1a-u was designed and synthesized, based upon a cyclohexyl lead compound. All members were evaluated as STS inhibitors in a cell-free assay. Adamantyl derivatives 1h and 1p-r were the most active with more than 90% inhibition at 10 µM concentration and
甾族硫酸酯酶(STS)最近已成为治疗激素依赖性恶性肿瘤的药物靶标。在本研究中,基于环己基铅化合物,设计并合成了一系列新的二十一个芳基酰胺基连接的氨基磺酸酯衍生物1a-u。在无细胞试验中将所有成员评估为STS抑制剂。金刚烷衍生物1h和1p-r在10 µM浓度下活性最高,抑制率超过90%,对于那些抑制活性最大的化合物,测定IC 50值。这些化合物在约25-110nM的范围内表现出STS抑制。其中,化合物1q具有o-氯苯磺酸氨基酯部分表现出最有效的STS抑制活性,IC 50为26 nM。此外,为了确保能够穿过细胞脂质双层,在JEG-3全细胞试验中针对STS活性测试了具有低IC 50值的化合物。因此,1h和1q的IC 50值分别约为14 nM和150 nM。因此,化合物1h的效力是相应的环己基铅的31倍(在JEG-3全细胞试验中,IC 50值= 421 nM)。此外,最有效的STS抑制剂(1h和1
