lobatamides to mammalian V-ATPase, three photoactivatable analogues bearing benzophenone photoaffinity labels have been prepared. The analogues were designed on the basis of a simplified acyclic analogue 2. Late-stage installation of the enamide side chain and tandem deallylation/amidation were employed in synthetic routes to these derivatives. Simplified analogue 2 showed strong inhibition against bovine
洛巴胺和相关的水杨酸酯烯酰胺天然产物是有效的哺乳动物V-ATPase抑制剂。为了探究洛巴酰胺与哺乳动物V-ATPase结合的细节,已经制备了三种带有二苯甲酮光亲和标记的可光活化类似物。这些类似物是在简化的无环类似物2的基础上设计的。在这些衍生物的合成途径中采用了酰胺侧链的后期安装和串联脱羧/酰胺化。简化的类似物2对牛网格蛋白包被的囊泡V-ATPase(10 nM)表现出强烈的抑制作用。类似物3 - 5,以选择用于将来光亲和标记研究的合适候选也评价抑制牛V-ATP酶的。
