A series of new malonamide derivatives were synthesized by Michael addition reaction of N1,N3-di(pyridin-2-yl)malonamide into α,β-unsaturated ketones mediated by DBU in DCM at ambient temperature. The inhibitory potential of these compounds in vitro, against α-glucosidase enzyme was evaluated. Result showed that most of malonamide derivatives were identified as a potent inhibitors of α-glucosidase
N 1,N 3-二(吡啶-2-基)丙二酰胺在室温下由DBU介导的α,β-不饱和酮的Michael加成反应合成了一系列新的丙二酰胺衍生物。评价了这些化合物在体外对α-葡萄糖苷酶的抑制潜力。结果表明,大多数丙二酰胺衍生物被认为是有效的α-葡萄糖苷酶抑制剂。在所有化合物中, 与标准药物阿卡波糖(IC 50 = 840±1.73μM)相比,发现4K(IC 50 = 11.7±0.5μM)是活性最高的化合物。进一步的细胞毒性为4a – 4m 还对许多癌症和正常细胞系进行了评估,并获得了有趣的结果。
