screening PL inhibitors, which generate numerous pPL inhibitors but the potent inhibitors against human PL (hPL) are rarely reported. Herein, a series of salicylanilide derivatives were designed and synthesized, while their anti-hPL effects were assayed by a fluorescence-based biochemical approach. To investigate the structure–activity relationships of salicylanilide derivatives as hPL inhibitors in detail
肥胖是一个日益严重的全球健康问题,并与许多代谢性疾病的患病率增加有关,包括糖尿病、高血压和心血管疾病。胰脂肪酶(PL)因其在脂质消化和吸收中的关键作用而被证实是开发抗肥胖药物的关键靶点。在过去的几十年里,猪PL(pPL)一直被用作筛选PL抑制剂的酶源,产生了大量的pPL抑制剂,但针对人PL(hPL)的强效抑制剂却很少报道。在此,设计并合成了一系列水杨酰苯胺衍生物,并通过基于荧光的生化方法测定了它们的抗 hPL 作用。为了详细研究水杨酰苯胺衍生物作为 hPL 抑制剂的构效关系,对水杨酰苯胺骨架的三个环(A、B 和 C)进行了结构修饰。在所有测试的化合物中,2t和2u被发现具有最有效的抗 PL 活性,IC50值分别为 1.86 μM 和 1.63 μM。抑制动力学分析表明,2t和2u均能以非竞争性方式有效抑制hPL,k i值分别为1.67 μM和1.70 μM。荧光猝灭测定表明两种抑制剂可以通过静态猝灭程序猝灭
