风霉素是由芽孢杆菌产生的环状脂质沉积肽,具有有效的抗真菌特性,但化学性质不稳定。这种不稳定性意味着没有发表过任何风霉素的全合成。本文报道了凤霉素A类似物的合成,该类似物在碱性和酸性条件下均表现出增强的抗真菌性能和化学稳定性。制备的类似物还表明,可以在不丧失抗真菌活性的情况下修饰和简化凤霉素的核心结构。
Fengycins are cyclic lipo-depsipeptides produced by Bacillus spp. that display potent antifungal properties but are chemically unstable. This instability has meant that no total synthesis of any fengycin has been published. Here we report the synthesis of fengycin A analogues that display enhanced antifungal properties and chemical stability under both basic and acidic conditions. The analogues prepared also demonstrate that the fengycin core structure can be modified and simplified without the loss of antifungal activity.
