Estrone sulfamate (EMATE) is a potent irreversible inhibitor of steroid sulfatase (STS). In order to further expand SAR, the compound was substituted at the 2- and/or 4-positions and its 17-carbonyl group was also removed. The following general order of potency against STS in two in vitro systems is observed for the derivatives: The 4-NO2 > 2-halogens, 2-cyano > EMATE (unsubstituted) > 17-deoxyEMA
氨基磺酸雌酮(EMATE)是一种强力不可逆的甾族硫酸酯酶(STS)抑制剂。为了进一步扩大SAR,将该化合物在2-和/或4-位取代,并且还除去其17-羰基。对于两个衍生物,在两个体外系统中观察到针对STS的以下一般效力顺序:4-NO 2 > 2-卤素,2-氰基> EMATE(未取代)> 17-脱氧EMATE> 2-NO 2 > 4-溴> 2-(2-丙烯基),2-正丙基> 4-(2-丙烯基),4-正丙基> 2,4-(2-丙烯基)= 2,4-二-n-丙基。将吸电子取代基放置在A环上具有明显的优势,而卤素优选在2位上,而硝基在4位上。在EMATE的2-和/或4-位上用2-丙烯基或正丙基取代,以及除去17-羰基对效能是有害的。设计的三种环状氨基磺酸盐不是STS抑制剂。这进一步证实,如EMATE和Irosustat抑制剂所示,游离或N-未取代的氨基磺酸酯基团(H 2 NSO 2 O–)是有效和不可
