Both five- and six-membered iminocyclitols have proven to be useful transition-state analogue inhibitors of glycosidases. They also mimic the transition-state sugar moiety of the nucleoside phosphate sugar in glycosyltransferase-catalyzed reactions. Described here is the development of a general strategy toward the parallel synthesis of a five-membered iminocyclitol linked to a hydroxamic acid group
已证明五元和六元亚氨基环醇都是有用的糖苷酶过渡态类似物抑制剂。他们还在糖基转移酶催化的反应中模拟了核苷磷酸糖的过渡态糖部分。在此描述的是一种通用策略的发展,该策略是平行连接与异羟肟酸基团连接的五元亚氨基环糖醇的,旨在模拟岩藻糖基转移酶反应中GDP-岩藻糖与Mn(II)的过渡态。由D-甘露糖醇制备含有受保护的羟胺单元的亚氨基环糖醇8。经由8与各种酰氯的反应引入异羟肟酸部分。该策略通常可用于构建糖基转移酶抑制剂的文库。
