Synthesis of new 6-ureido-4-anilinoquinazolines have been accomplished and their in vitro antimalarial activity against chloroquine-sensitive P. falciparum have been examined. Out of 64 compounds evaluated, the IC50 of 16 compounds which have displayed MIC of 0.25 μg/mL were also recorded. One of the compounds (24g) had IC50 value of 2.27 ng/mL which was equipotent to the standard drug chloroquine
已经完成了新的6-脲基-4-苯胺基喹唑啉的合成,并且已经研究了它们对氯喹敏感的恶性疟原虫的体外抗疟活性。在评估的64种化合物中,还记录了MIC值为0.25μg/ mL的16种化合物的IC 50值。其中一种化合物(24g)的IC 50值为2.27 ng / mL,与生物测定中使用的标准药物氯喹等效。导致一个模拟的发现该系列中的几种化合物的体内评价(30克)显示40%的治疗活性(28天)对MDR P. yoeilli nigeriensis在100毫克/公斤×4天的口服剂量。
