series of catechol and dioxolane analogs containing thiazole CGA derivatives have been synthesized and evaluated for their inhibitory activity against α-MSH. The inhibitory activity was improved by replacing an α,β-unsaturated carbonyl of previously reported caffeamides with thiazole motif. Surprisingly, compound 7d, one of the derivatives of dioxolane analogs, displayed the most potent inhibitory activity
合成了一系列含有噻唑CGA衍生物的邻苯二酚和二氧戊环类似物,并评估了其对α-MSH的抑制活性。通过用噻唑基序代替先前报道的咖啡酰胺的α,β-不饱和羰基,可以提高抑制活性。出乎意料的是,化合物2d是二氧戊环类似物的衍生物之一,显示出最有效的抑制活性,IC 50为0.90μM。还完成了对代谢稳定性和生物激活潜力的进一步研究。
