and evaluated for antiplasmodial activity in vitro. Antimalarial activity has been investigated as for the final peptide mimetics, and their immediate predecessors, carrying TBDMS or TBDPS protecting groups on 4‐hydroxyproline residue and 18 derivatives exhibited toxicity against P. falciparum. Of these agents, compound 23e was shown to have potent antimalarial activity with IC50 528 ng/ml.
设计、合成了一系列新的拟肽 N 取代的 Cbz-4-Hyp-Hpa-酰胺,并评估其对恶性疟原虫的抑制作用。酰胺基团 N 原子上的取代基为烷基-、烯丙基-、芳基-、2-羟乙基-、2-氰乙基-、氰甲基-、2-羟乙基-、2,2-二乙氧基乙基-或2-乙氧基合成了 -2-氧乙基氨基和大约 40 种新化合物,并在体外评估了抗疟原虫活性。已经研究了最终肽模拟物的抗疟活性,它们的直接前身在 4-羟脯氨酸残基上带有 TBDMS 或 TBDPS 保护基团,18 种衍生物对恶性疟原虫表现出毒性。在这些药剂中,化合物 23e 显示具有有效的抗疟活性,IC50 为 528 ng/ml。
