A series of 2-pyrazolyl quinolones has been designed and synthesized in 5-7 steps to optimize for both in vitro antimalarial potency and various in vitro drug metabolism and pharmacokinetics (DMPK) features. The most potent compounds display no cross-resistance with multidrug resistant parasite strains (W2) compared to drug sensitive strains (3D7), with IC50 (concentration of drug required to achieve
已经设计并合成了一系列2-吡唑基喹诺酮类药物,分5-7个步骤进行了优化,以优化体外抗疟药功效以及各种体外药物代谢和药代动力学(DMPK)功能。与对药物敏感的菌株(3D7)相比,最有效的化合物与对多药耐药的寄生虫菌株(W2)没有交叉耐药性,IC50(达到最大最大生长抑制一半所需的药物浓度)值在15-33 nM之间。此外,该系列的成员保留了对耐阿托伐醌的寄生虫分离物(TM90C2B)的中等活性。所述的2-吡唑酰基系列显示出改善的DMPK特性,与先前报道的喹诺酮系列相比具有改善的水溶性,并且通过体外细胞毒性评估具有可接受的安全范围。
