A library of quinoline-based hydrazones bearing 1H-1,2,3-triazole core was designed, synthesized, and evaluated for their antiplasmodial activity against the drug-resistant Plasmodium falciparum W2 strain. The inclusion of pyrazine-2-carboxylic acid with a flexible propyl spacer afforded the most active scaffold with an IC50 value of 0.26 μM. Mechanistically, the compound inhibited heme to hemozoin
设计、合成并评估了带有 1 H -1,2,3-三唑核的基于喹啉的腙库,并评估了它们对耐药性恶性疟原虫W2 株的抗疟原虫活性。吡嗪-2-羧酸与柔性丙基间隔物的结合提供了最活跃的支架,其 IC 50值为 0.26 μM。从机制上讲,该化合物抑制了血红素向疟原虫色素的形成,正如紫外可见光谱和质谱研究所证明的那样。

A targeted series of chalcone and dienone hybrid compounds containing aminoquinoline and nucleoside templates was synthesized and evaluated for in vitro antimalarial activity. The Cu(I)-catalyzed cycloaddition of azides and terminal alkynes was applied as the hybridization strategy. Several chalcone-chloroquinoline hybrid compounds were found to be notably active, with compound 8b the most active, exhibiting submicromolar IC50 values against the D10, Dd2 and W2 strains of Plasmodium falciparum.
