sleeping sickness. Starting from known inhibitors of other glycosyltransferases, we have developed the first small molecular inhibitors of dolicholphosphate mannose synthase (DPMS), a mannosyltransferase critically involved in glycoconjugate biosynthesis in T. brucei. We show that these DPMS inhibitors prevent the biosynthesis of glycosylphosphatidylinositol (GPI) anchors, and possess trypanocidal activity
迫切需要具有抗布氏锥虫活性的类药物分子作为治疗非洲昏睡病的潜在疗法。从已知的其他糖基转移酶抑制剂开始,我们开发了第一个多羟基磷酸甘露糖合酶 (DPMS) 的小分子抑制剂,DPMS 是一种与T. brucei糖复合物生物合成密切相关的甘露糖基转移酶。我们发现这些 DPMS 抑制剂可阻止糖基磷脂酰肌醇 (GPI) 锚的生物合成,并对活锥虫具有杀锥虫活性。
