diverse set of flavones, isosteric to 4(1H)-quinolones, were prepared and profiled for their antiplasmodial activity against the blood stage of P. falciparum W2 strain, and the liver stage of the rodent parasite Plasmodium berghei. Ligand efficient leads were identified as dual stage antimalarials, suggesting that scaffold optimization may afford potent antiplasmodial compounds.
疟疾每年导致近一百万人死亡,恶性疟原虫的多抗性菌株的日益流行给控制该疾病带来了巨大挑战。制备了与4(1 H)-喹诺酮等排的多种黄酮,并对其抗恶性疟原虫W2菌株的血液阶段和鼠寄生虫伯氏疟原虫的肝脏阶段的抗疟原虫活性进行了分析。配体有效的潜在客户被确定为双阶段抗疟药,这表明支架优化可以提供有效的抗疟原虫化合物。
