protein 35, FKBP35, has been implicated as an essential malarial enzyme. Rapamycin and FK506 exhibit antiplasmodium activity in cultured parasites. However, due to the highly conserved nature of the binding pockets of FKBPs and the immunosuppressive properties of these drugs, there is a need for compounds that selectively inhibit FKBP35 and lack the undesired side effects. In contrast to human FKBPs, FKBP35
FK506结合蛋白35,FKBP35,已被认为是必需的疟疾酶。雷帕霉素和FK506在培养的寄生虫中表现出抗疟原虫活性。然而,由于FKBP的结合口袋的高度保守的性质和这些药物的免疫抑制特性,需要选择性地抑制FKBP35并且缺乏不良副作用的化合物。与人FKBP相比,FKBP35在雷帕霉素结合口袋附近包含一个半胱氨酸C106,为开发靶向疟原虫FKBP35的共价抑制剂提供了机会。在这里,我们合成了FKBP35的抑制剂,表明它们在模型细胞环境中直接结合FKBP35,选择性地共价修饰C106,并在血阶段培养的寄生虫中表现出抗疟原虫活性。
