Developing potent 5-LOX inhibitors especially, natural product based ones, are highly attractive. Coumaperine, a natural product found in white pepper and its derivatives were herein developed as 5-LOX inhibitors. We have synthesized twenty four derivatives, characterized and evaluated their 5-LOX inhibition potential. Coumaperine derivatives substituted with multiple hydroxy and multiple methoxy groups
5-Lipoxygenase(5-LOX)是参与促炎性白三烯生物合成的关键酶,可导致哮喘。开发有效的5-LOX抑制剂,特别是基于天然产物的抑制剂,具有很高的吸引力。香豆碱是白胡椒及其衍生物中的天然产物,在本文中被开发为5-LOX抑制剂。我们已经合成了二十四个衍生物,表征并评估了它们对5-LOX的抑制潜力。取代有多个羟基和多个甲氧基的香豆碱衍生物表现出最佳的5-LOX抑制作用。CP-209(一种邻苯二酚型二羟基衍生物)和CP-262-F2(一种邻位三羟基衍生物)在20 µM时分别显示出对5-LOX的抑制率为82.7%和82.5%。它们的IC50值分别为2.1±0.2 µM和2.3±0.2 µM,与齐留通相当,IC50 = 1.4±0.2 µM。CP-155,亚甲基二氧基衍生物(天然产物)和CP-194(2,4,6-三甲氧基衍生物)在20 µM时分别显示出对5-LOX的抑制率为76.0%和77
