  Discovery, Synthesis, and Optimization of Antimalarial 4(1H)-Quinolone-3-Diarylethers

  摘要：

  The historical antimalarial compound endochin served as a structural lead for optimization. Endochin-like quinolones (ELQ) were prepared by a novel chemical route and assessed for in vitro activity against multidrug resistant strains of Plasmodium falciparum and against malaria infections in mice. Here we describe the pathway to discovery of a potent class of orally active antimalarial 4(1H)-quinolone-3-diarylethers. The initial prototype, ELQ-233, exhibited low nanomolar IC50 values against all tested strains including clinical isolates harboring resistance to atovaquone. ELQ-271 represented the next critical step in the iterative optimization process, as it was stable to metabolism and highly effective in vivo. Continued analoging revealed that the substitution pattern on the benzenoid ring of the quinolone core significantly influenced reactivity with the host enzyme. This finding led to the rational design of highly selective ELQs with outstanding oral efficacy against murine malaria that is superior to established antimalarials chloroquine and atovaquone.

  ELQ-300、ELQ-316 和其他抗寄生虫喹诺酮类药物的新可扩展合成路线

  摘要：

  内啡肽样喹诺酮 (ELQ) 化合物类可以为一系列重要的人类和动物疾病提供有效、安全的治疗方法。然而，为了获得该化合物系列的公共卫生潜力，需要设计一种合成路线，该路线将降低成本并适合大规模生产。在这里描述的新合成路线中，通过 Ullmann 反应和随后的酰化形成取代的 β-酮酯，通过 Conrad-Limpach 反应与苯胺反应生成 3-取代的 4( 1H )-喹诺酮类，例如ELQ -300和ELQ-316. 该合成路线首次被描述为真正适合工业规模生产，相对较短（五个反应步骤），不需要钯、色谱分离或保护基化学，并且可以在没有高真空蒸馏的情况下进行。
