steroidal and nonsteroidal sulfamate-based active site-directed inhibitors of the enzyme steroid sulfatase, a topical target in the treatment of postmenopausal women with hormone-dependent breast cancer, are described. Novel compounds were examined for estrone sulfatase (E1-STS) inhibition in intact MCF-7 breast cancer cells and placental microsomes. Reaction of the sodium salt of estrone with sulfamoyl
描述了合成有效途径的类固醇和非类固醇氨基磺酸盐类酶类固醇硫酸酯酶的活性定点抑制剂的途径,类固醇硫酸酯酶是绝经后妇女激素依赖型乳腺癌的治疗中的局部靶标。检查了新化合物对完整MCF-7乳腺癌细胞和胎盘微粒体中的雌酮硫酸酯酶(E1-STS)的抑制作用。雌酮的钠盐与氨磺酰氯反应,得到雌酮3-O-氨基磺酸酯(EMATE,2),可有效抑制E1-STS活性(在完整的MCF-7细胞中,0.1 microM时> 99%,IC50 = 65 pM)。时间和浓度依赖性,表明EMATE是一种活性的定点抑制剂。EMATE还具有体内口服活性。合成了5,6,7,8-四氢萘2-O-氨基磺酸盐(7)及其N-甲基化衍生物(8和9),7和10在10 microM时可将完整的MCF-7细胞中的E1-STS活性抑制79%。制备4-甲基香豆素7-O-氨基磺酸盐(COUMATE)及其衍生物(14、16和18)以扩展该系列非甾体抑制剂,并且COUMATE在10
