  Malaria and leishmaniasis are two of the World’s most important tropical parasitic diseases. Thirteen new 2-cyano-3-(4-phenylpiperazine-1-carboxamido) quinoxaline 1,4-dioxide derivatives (CPCQs) were synthesized and evaluated for their in vitro antimalarial and antileishmanial activity against erythrocytic forms of Plasmodium falciparum and axenic forms of Leishmania infantum. Their toxicity against VERO cells (normal monkey kidney cells) was also assessed. None of the tested compounds was efficient against Plasmodium, but two of them showed good activity against Leishmania. Toxicity on VERO was correlated with leishmanicidal properties.

  疟疾和利什曼病是世界上最重要的两种热带寄生虫病。合成了13种新型2-氰基-3-(4-苯基哌嗪-1-羧酰胺)喹喔啉-1,4-二氧化物衍生物(CPCQs),并评估了它们对红细胞内恶性疟原虫(Plasmodium falciparum)和无菌利什曼原虫(Leishmania infantum)形式的体外抗疟和抗利什曼活性。同时,评估了它们对VERO细胞(正常猴肾细胞)的毒性。测试化合物均对疟原虫无效,但其中两种对利什曼原虫显示出良好活性。对VERO的毒性与抗利什曼特性相关。
