Several members of a new family of non-sugar-type α-glucosidase inhibitors, bearing a phthalimide moiety connected to a variously substituted phenoxy ring by an alkyl chain, were synthesized and their activities were investigated. The efficacy of the inhibition activity appeared to be governed by the chain length of the substrate. Substrates possessing 10 carbons afforded the highest levels of activity
合成了一个新的非糖型α-葡萄糖苷酶抑制剂家族的成员,这些抑制剂带有通过烷基链连接到各种取代的苯氧基环上的邻苯二甲酰亚胺部分,并研究了它们的活性。抑制活性的功效似乎由底物的链长决定。具有10个碳原子的底物具有最高水平的活性,其活性比已知的抑制剂1-脱氧野oji霉素(dNM)强一到两个数量级。此外,结构与活性之间的关系研究表明,苯氧基上的吸电子取代基对于该活性起着至关重要的作用。该系列中最有效的衍生物是带有氯原子以及强吸电子基团(例如硝基)的衍生物。
