Introduction of water-solubilizing groups on the 5-phenyl ring of a 2-aminopyrazine series led to the identification of highly potent compounds against the blood life-cycle stage of the human malaria parasite Plasmodium falciparum. Several compounds displayed high in vivo efficacy in two different mouse models for malaria, P. berghei-infected mice and P. falciparum-infected NOD-scid IL-2Rγnull mice
在2-氨基吡嗪系列的5-苯基环上引入水溶性基团导致鉴定出针对人类疟疾寄生虫恶性疟原虫血液生命周期阶段的高效化合物。在两种不同的疟疾小鼠模型中,几种化合物在疟疾,伯氏疟原虫感染的小鼠和恶性疟原虫感染的NOD -scidIL-2Rγ无效小鼠中表现出很高的体内功效。领先者之一化合物3被确定为还具有良好的药代动力学,并且还具有针对肝脏和配子细胞寄生虫生命周期阶段的非常有效的活性。
