寄生性半胱氨酸蛋白酶,例如来自罗得西亚锥虫的罗地赛因 ( Tb CatL )是开发针对寄生虫病(例如人类非洲锥虫病)的新的潜在药物的相关靶标。为寄生组织蛋白酶设计选择性抑制剂可能具有挑战性,因为它们与人类组织蛋白酶具有高度的结构相似性。在本文中,我们通过应用基于结构的从头设计方法和分子对接协议描述了新型拟肽罗地塞因抑制剂的开发。在 P2 和 P3 位置具有新支架的抑制剂对锥体罗地赛因的选择性高于对人组织蛋白酶 L 和 B 的选择性和高的抗锥体活性。乙烯基磺酸盐2a已成为一种有效的罗地塞因抑制剂 ( k 2nd = 883 • 10 3 M -1 s -1 ),具有个位数的纳摩尔结合亲和力 ( K i = 9 nM),对人体组织蛋白酶的选择性超过 150 倍,因此构成一种有趣的起始化合物,用于进一步开发针对人类非洲锥虫病的选择性药物。

members of the Epsilonproteobacteria (Campylobacter and Helicobacter). Amixicile selectively inhibits pyruvate-ferredoxin oxidoreductase (PFOR) and related enzymes by inhibiting the function of the vitaminB1 cofactor (thiamine pyrophosphate) by a novel mechanism. Here, we interrogate the amixicile scaffold, guided by docking simulations, direct PFOR inhibition assays, and MIC tests against Clostridium
