The Plasmodium falciparum cysteine protease falcipain-2, one of the most promising targets for antimalarial drug design, plays a key role in parasite survival as a major peptide hydrolase within the hemoglobin degradation pathway. In this work, a series of novel dihydroartemisinin derivatives based on (thio)semicarbazone scaffold were designed and synthesized as potential falcipain-2 inhibitors. The
恶性疟原虫半胱氨酸蛋白酶 falcipain-2 是抗疟药物设计中最有希望的靶点之一,作为血红蛋白降解途径中的主要肽水解酶,在寄生虫存活中起着关键作用。在这项工作中,设计并合成了一系列基于(硫代)缩氨基脲支架的新型双氢青蒿素衍生物作为潜在的 falcipain-2 抑制剂。体外生物测定表明,大多数目标化合物对 P. falciparum falcipain-2 显示出优异的抑制活性,IC(50) 值在 0.29-10.63 μM 范围内。进行分子对接研究以研究抑制剂的结合亲和力和相互作用模式。总结了初步的SARs,可以作为进一步研究抗疟药物开发的基础。
