the treatment of infections. We recently reported the development of a novel antimalarial drug that combines the 4-aminoquinoline pharmacophore of chloroquine with that of clotrimazole-based antimalarials. Here we describe the optimization of this class of hybrid drug through in-depth structure–activity relationship studies. Antiplasmodial properties and mode of action were characterized in vitro and
尽管最近在抗击疟疾方面取得了进展,但耐药性寄生虫的出现和扩散仍然是感染治疗的严重障碍。我们最近报道了一种新型抗疟药的开发,该药结合了氯喹的4-氨基喹啉药效基团和基于克霉唑的抗疟药。在这里,我们通过深入的结构-活性关系研究来描述这类杂合药物的优化。在体外和体内表征了抗疟原虫的性质和作用方式,并在非洲爪蟾卵母细胞表达系统中研究了与寄生虫的“氯喹抗性转运蛋白”的相互作用。这些测试表明哌嗪衍生物4b和4d可能适合与氯喹共同使用,以抵抗耐氯喹的寄生虫。在计算机上测定了细胞色素P450代谢药物的潜力,并测试了先导化合物的毒性和致突变性。在小鼠中进行的初步药代动力学分析表明,化合物4b具有最佳的半衰期。
