Based on the significant anti-inflammatory activity of natural quinone primin (5a), series of 1,4-benzoquinones, hydroquinones, and related resorcinols were designed, synthesized, characterized and tested for their ability to inhibit the activity of cyclooxygenase (COX-1 and COX-2) and 5-lipoxygenase (5-LOX) enzymes. Structural modifications resulted in the identification of two compounds 5b (2-methoxy-6-undecyl-1
基于天然醌primin(5a)的显着抗炎活性,设计,合成,表征和测试了一系列1,4-苯醌,对苯二酚和相关间苯二酚抑制环氧化酶(COX-1)的能力。和COX-2)和5-脂氧合酶(5-LOX)酶。结构修饰导致鉴定出两种化合物5b(2-甲氧基-6-十一烷基-1,4-苯醌)和6b(2-甲氧基-6-十一烷基-1,4-氢醌)作为有效的双重COX / 5-LOX抑制剂。使用酶促测定在体外评估的IC 50值对于化合物5b为IC 50 = 1.07、0.57和0.34μM,对于化合物6b对于COX-1,COX-2和5-LOX酶,IC 50分别为1.07、0.55和0.28μM。此外,化合物6d被鉴定为测试化合物中最有效的5-LOX抑制剂(IC 50 = 0.14μM;参考抑制剂齐留通IC 50 = 0.66μM),而其对COX酶的抑制潜力(IC 50 = 2.65和2.71μM对于COX-1和COX-2的浓度分别与参考抑制剂布洛芬(IC
