Inspired by the significant -glucosidase inhibitory activities of (+)- and (-)-pericosine E, we herein designed and synthesized 16 analogs of these marine natural products bearing a methoxy group instead of a chlorine atom at C6. Four of these compounds exhibited moderate -glucosidase inhibitory activities, which were weaker than those of the corresponding chlorine-containing species. The four compounds
受(+)-和(-)-pericosine E的α-
葡萄糖苷酶显着抑制活性的启发,我们在此设计和合成了这些海洋
天然产物的16个类似物,这些类似物在C6处带有甲氧基而不是
氯原子。这些化合物中的四种表现出中等的β-
葡萄糖苷酶抑制活性,比相应的含
氯物质弱。可以通过利用(-)-pericosine B部分进行偶联反应来制备这四种化合物。另外的计算机对接模拟表明,C6-甲氧基化类似物的活性降低的原因可能是甲氧基与β-
葡糖苷酶活性位点周围的
氨基酸残基之间没有氢键。
