A series of ferrocenylchalcone-β-lactam conjugates were synthesized and evaluated against 3D7 (CQ-Sensitive) and W2 (CQ-Resistant) strains of Plasmodium falciparum. The SAR studies revealed the dependence of activities at N-1 substituent of β-lactam ring with compounds being more potent on resistant strain. The compound 9f and 9l with N-cyclohexyl substituent proved to be the most potent and non-cytotoxic among the series exhibiting IC50 values of 2.36 and 2.43 μM respectively, against W2 strain of P. falciparum.
合成了一系列二茂铁基查尔酮-β-内酰胺缀合物，并针对恶性疟原虫的3D7（对氯喹敏感）和W2（对氯喹耐药）菌株进行了评估。构效关系研究表明，β-内酰胺环N-1取代基的活性具有依赖性，化合物对耐药菌株的活性更强。在该系列化合物中，具有N-环己基取代基的化合物9f和9l被证明是最有效的且无细胞毒性，对恶性疟原虫W2菌株的IC50值分别为2.36和2.43 μM。
