Bioassay guided fractionation from corn gluten meal, a byproduct of a starch manufacturing plant, gave N-p-coumaroyl-N'-feruloylputrescine (1) and N,N'-diferuloylputrescine (2) as alpha-glucosidase inhibitors. Some structure-activity relationships were studied by comparing the inhibitory activity by preparing some related compounds, and it was revealed that the hydroxyl group was important for the
生物测定法指导从淀粉制造厂的副产品玉米蛋白粉分馏,得到了Np-香豆酰基-N'-阿魏酰putrescine(1)和N,N'-二磺酰基putrescine(2)作为α-葡萄糖苷酶抑制剂。通过比较制备一些相关化合物的抑制活性,研究了一些构效关系,结果表明羟基对双酰胺生物碱的抑制活性很重要,但对氧化还原电位却不重要。
