Most compounds exhibited low micromolar antiplasmodial activities against the P. falciparum drug resistant W2 strain. The most active compounds of the series were tested for in vitro microsomal metabolic stability and found to be susceptible to hepatic metabolism. Subsequent metabolite identification studies highlighted the metabolic hot spots. Molecular docking studies of a frontrunner inhibitor
在基于结构的虚拟筛选之后,合成了一系列的2,4噻唑烷二酮,以探索结构活性关系,以抑制恶性疟原虫半胱氨酸蛋白酶falcipain-2(FP-2)和全细胞抗寄生虫活性。大多数化合物对恶性疟原虫耐药的W2株表现出较低的微摩尔抗疟原虫活性。该系列中活性最高的化合物已在体外进行了测试微粒体的代谢稳定,发现对肝代谢敏感。随后的代谢物鉴定研究突出了代谢热点。进行了对前沿抑制剂的分子对接研究,以确定此类抑制剂在FP-2活性位点的可能结合方式。
