Visceral leishmaniasis is a potentially fatal disease caused by infection by the intracellular protist pathogens or . Present therapies are ineffective because of high costs, variable efficacy against different species, the requirement for hospitalization, toxicity and drug resistance. Detailed analysis of previously published hit molecules suggested a crucial role of ‘guanidine’ linkage for their
内脏利什曼病是一种由细胞内原生生物病原体感染引起的潜在致命性疾病。目前的疗法由于成本高、针对不同物种的疗效不同、需要住院、毒性和耐药性而无效。对先前发表的命中分子的详细分析表明,“胍”连接对于其对抗 .在这里,我们报告了 2-氨基喹唑啉杂环的设计作为带有基本药效团的胍键。使用生理相关的 THP-1 转化巨噬细胞感染模型,在喹唑啉支架的不同位置引入各种基团和功能,可增强抗寄生虫效力,并具有适度的宿主细胞细胞毒性。就 ADME 谱而言,喹唑啉的 C7 位置被确定为设计更好分子的指导工具。这些化合物良好的 ADME 特征表明它们值得进一步考虑作为治疗内脏利什曼病的先导化合物。
