trypanosomatid parasite's defense against oxidative stress and has emerged as a promising target for antitrypanosomal drugs. We describe the synthesis and activity of dethiotrypanothione and analogues (2−4) as inhibitors of Trypanosoma cruzi TR. The syntheses of these macrocycles feature ring-closing olefin metathesis (RCM) reactions catalyzed by ruthenium catalyst 17. Derivative 4 is our most potent
锥虫硫醚还原酶(TR)催化NADPH依赖性的锥虫硫醚二硫化物的还原(1)。TR在锥虫病寄生虫对氧化应激的防御中起着核心作用,并已成为抗锥虫病药物的有希望的靶标。我们描述了合成和dethiotrypanothione和类似物(活性2 - 4)作为抑制剂的克氏锥虫TR。这些大环的合成具有钌催化剂17催化的闭环烯烃复分解(RCM)反应。衍生物4是我们最有效的抑制剂,K i = 16μM。
