A series of new 21 chloroquine heterocyclic hybrids containing either benzylamino fragment or N-(aminoalkyl)thiazolidin-4-one moiety were synthesized and screened for their antimalarial activity against chloroquine (CQ)-sensitive 3D7 and multidrug-resistance Dd2 strains of Plasmodium falciparum. Although no compounds more active than CQ against 3D7 was found; against Dd2 strain, six compounds, four
合成了一系列新的21个含苄基氨基片段或N-(氨基烷基)噻唑烷丁-4-酮部分的氯喹杂环杂种,并筛选了它们对恶性疟原虫对氯喹(CQ)敏感的3D7和耐多药Dd2菌株的抗疟活性。尽管没有发现对3D7的活性比CQ高的化合物。针对Dd2菌株,六种化合物(其中四种具有苄基氨基片段)显示出优异的活性,活性最高是CQ的3倍。在某些化合物中观察到了对J774巨噬细胞的非特异性细胞毒性,而其中只有两个对HepG2细胞显示了肝毒性。此外,所有活性化合物均以约CQ的浓度抑制了铁原卟啉IX的生物结晶过程。体内初步结果表明,至少有两种化合物对伯氏疟原虫ANKA具有与CQ相同的活性。
