Novel imidazo[4,5-c]quinolin-2-ones were synthesized and evaluated in asexual blood stage and late stage gametocyte assays of Plasmodium falciparum, a major causative agent of malaria. The design of these compounds is based on a recently identified lead compound from a high throughput screen. A concise synthesis was developed that allowed for generation of analogues with substitution around both the
合成了新型咪唑并[4,5-c]喹啉-2-酮,并在疟疾的主要病原体恶性疟原虫的无性血液阶段和晚期配子细胞测定中进行了评估。这些化合物的设计基于最近从高通量筛选中鉴定出的先导化合物。开发了一种简明的合成方法,该方法可生成在喹啉和咪唑烷酮环上均被取代的类似物。通过结构-活性关系研究,鉴定了许多有效的化合物,它们对无性和有性阶段均具有优异的抗疟活性,并且在哺乳动物细胞中具有最小的细胞毒性。这是第一封描述咪唑并[4,5-c]喹啉-2-酮(一种新的用于治疗和预防疟疾的先导系列产品)的SAR和杀真菌活性的第一封信。
