A series of 3-styrylchromone derivatives (4–20) were synthesized and the structure–activity relationships for α-glucosidase inhibition and antioxidant activities were analyzed. Among the synthesized compounds, compounds 15 and 20, which contain a catechol moiety, showed both potent 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity (15: EC50=17 µM; 20: EC50=23 µM) and α-glucosidase inhibitory activity (15: IC50=16 µM; 20: IC50=10 µM). Our data suggest that 3-styrylchromone derivatives are novel α-glucosidase inhibitors that have the potential to counteract diet-induced hyperglycemia in diabetes.
合成了一系列 3-苯乙烯基色酮衍生物(4-20),并分析了其抑制α-葡萄糖苷酶和抗氧化活性的结构-活性关系。在合成的化合物中,含有儿茶酚分子的化合物 15 和 20 同时显示出强大的 1,1-二苯基-2-苦基肼(DPPH)自由基清除活性(15:EC50=17 µM;20:EC50=23 µM)和α-葡萄糖苷酶抑制活性(15:IC50=16 µM;20:IC50=10 µM)。我们的数据表明,3-strylchromone 衍生物是新型的 α-葡萄糖苷酶抑制剂,具有抵消饮食引起的糖尿病高血糖的潜力。
