A series of N2,N4-disubstituted quinazoline-2,4-diamines has been synthesized and tested against Leishmania donovani and L. amazonensis intracellular amastigotes. A structure–activity and structure–property relationship study was conducted in part using the Topliss operational scheme to identify new lead compounds. This study led to the identification of quinazolines with EC50 values in the single
一系列Ñ 2,Ñ 4二取代喹唑啉-2,4-二胺已经合成和对所测试的杜氏利什曼原虫和亚马逊利什曼原虫细胞内无鞭毛体。部分使用 Topliss 操作方案进行了结构-活性和结构-性质关系研究,以确定新的先导化合物。除了有利的物理化学性质外,该研究还鉴定出 EC 50值在个位数微摩尔或高纳摩尔范围内的喹唑啉。喹唑啉23在内脏利什曼病的小鼠模型中也显示出疗效,当通过腹膜内途径以 15 mg kg 给药时,可将肝脏寄生虫血症减少 37%–1天–1连续 5 天。N 2 , N 4 -二取代喹唑啉-2,4-二胺化合物系列具有抗利什曼原虫功效、易于合成和良好的物理化学性质,使其成为未来开发抗利什曼虫剂的合适平台。
