Reversed chloroquine (RCQ) is a multiple ligand compound active against chloroquine-sensitive and resistant falciparum malaria. It is composed by a 4-aminoquinoline moiety (like that present in chloroquine (CQ)) joined to imipramine (IMP), a modulating agent that also showed intrinsic antiplasmodial activity against Brazilian Plasmodium falciparum isolates resistant to CQ. Molecular modeling and ultraviolet-visible spectroscopy (UV-vis) studies strongly suggest that the interaction between RCQ and heme is predominant through the quinoline moiety in a mechanism of action similar to that observed for CQ.
抗疟有效化合物 RCQ 是一种多配体化合物，对敏感和耐药恶性疟原虫均有活性。它由 4-氨基喹啉部分（与氯喹 （CQ） 相同）与丙咪嗪（IMP）组成，IMP 是一种调节剂，对巴西耐 CQ 的恶性疟原虫分离株也具有内在的抗疟原虫活性。分子建模和紫外可见光谱 （UV-vis） 研究强烈表明，RCQ 与血红素的相互作用主要通过喹啉部分，其作用机制与观察到的 CQ 相似。
