Herein we report the synthesis of a set of constrained peptidomimetics endowed with an electrophilic vinyl ester warhead and structurally related to a previously identified lead compound, a potent and irreversible inhibitor of falcipain‐2 (FP‐2). FP‐2 is the main hemoglobinase of the malaria parasite P. falciparum. The new compounds were evaluated for their inhibition against FP‐2, and the results
在本文中,我们报告了一组受约束的拟肽模拟物的合成,这些拟肽模拟物具有亲电子的乙烯基酯战斗部,并且在结构上与先前鉴定的铅化合物(一种有效且不可逆的falcipain-2(FP-2)抑制剂)相关。FP-2是疟原虫恶性疟原虫的主要血红蛋白酶。评估了新化合物对FP-2的抑制作用,并根据对接实验对结果进行了合理化。这些研究强调了P1'位上的酯功能和P3侧链的三氟甲基在确定Michael受体战斗部在催化位中的正确取向方面的关键作用,以及因此而产生的抑制剂的作用。以及其可逆或不可逆的抑制方式。
