Novel rhodesain inhibitors were obtained by combining an enantiomerically pure 3‐bromoisoxazoline warhead with a specific peptidomimetic recognition moiety. All derivatives behaved as inhibitors of rhodesain, with low micromolar Ki values. Their activity against the enzyme was found to be paralleled by an in vitro antitrypanosomal activity, with IC50 values in the mid‐micromolar range. Notably, a preference
通过将对映体纯的3-溴异恶唑啉战斗部与特定的拟肽识别部分相结合,可获得新型的罗德萨因抑制剂。所有衍生物均表现为罗得沙星的抑制剂,其微摩尔K i值低。发现它们对酶的活性与体外抗锥虫活性平行,IC 50值在中微摩尔范围内。值得注意的是,观察到寄生虫优于人蛋白酶,特别是组织蛋白酶B和L。
