Abstract

We have investigated the contribution of drug accumulation and inhibition of heme polymerization to the in vitro activities of a series of antimalarial drugs. Only those compounds exhibiting structural relatedness to the quinolines inhibited heme polymerization. We could find no direct correlation between in vitro activity against chloroquine-susceptible or chloroquine-resistant isolates and either inhibition of heme polymerization or cellular drug accumulation for the drugs studied. However, in vitro activity against a chloroquine-susceptible isolate but not a chloroquine-resistant isolate showed a significant correlation with inhibition of heme polymerization when the activity was normalized for the extent of drug accumulation. The importance of these observations to the rational design of new quinoline-type drugs and the level of agreement of these conclusions with current views on quinoline drug action and resistance are discussed.

摘要

我们研究了药物蓄积和血红素聚合抑制对一系列抗疟药物体外活性的作用。只有那些与喹啉结构相关的化合物能抑制血红素聚合。对于所研究的药物,我们未发现其对氯喹敏感或氯喹耐药分离株的体外活性与血红素聚合抑制或细胞内药物蓄积之间存在直接关联。然而,当针对药物蓄积程度对活性进行标准化处理时,对氯喹敏感分离株而非氯喹耐药分离株的体外活性与血红素聚合抑制呈现出显著相关性。本文讨论了这些观察结果对于新型喹啉类药物合理设计的重要性以及这些结论与当前关于喹啉类药物作用和耐药性观点的契合程度。
