submicromolar inhibition of Plasmodium falciparum FK506 binding domain 35 (FKBD35) PPIase activity. SRA and its analogues not only inhibit the in vitro growth of Plasmodium falciparum 3D7 strain but also show stage specific activity by inhibiting the trophozoite stage of the parasite. SRA/4a also inhibits the Plasmodium vivax FKBD35 PPIase activity and our crystal structure of PvFKBD35 in complex with
疟原虫物种中的FKP35,FK506结合蛋白家族成员,显示出规范的肽基脯氨酰异构酶(PPIase)活性,并复杂地参与了蛋白质折叠过程。FK506或其类似物对PfFKBP35的抑制作用会干扰恶性疟原虫的体外生长。在这项研究中,我们合成了金刚烷基衍生物Supradamal(SRA / 4a)及其类似物SRA1 / 4b和SRA2 / 4c,它们证明了亚微摩尔抑制恶性疟原虫FK506结合域35(FKBD35)PPIase活性。SRA及其类似物不仅抑制恶性疟原虫3D7菌株的体外生长,而且还通过抑制寄生虫的滋养体阶段而显示出阶段比活性。
