In this research, we exploited derivatives of thieno[2,3-b]pyridine as dual inhibitors of the key enzymes in eicosanoid biosynthesis, cyclooxygenase (COX, subtypes 1 and 2) and 5-lipoxygensase (5-LOX). Testing these compounds in a rat paw oedema model revealed potency higher than ibuprofen. The most active compounds 7a, 7b, 8b, and 8c were screened against COX-1/2 and 5-LOX enzymes. Compound 7a was
在这项研究中,我们利用噻吩并[2,3-b]吡啶衍生物作为类二十烷酸生物合成关键酶,环氧合酶(COX,亚型1和2)和5-脂氧合酶(5-LOX)的双重抑制剂。在大鼠爪水肿模型中测试这些化合物显示出比布洛芬更高的效力。针对COX-1 / 2和5-LOX酶筛选出活性最高的化合物7a,7b,8b和8c。化合物7a是5-LOX的最有效抑制剂,IC50 = 0.15 µM,而其对氯类似物7b对COX-2的活性更高(IC50 = 7.5 µM)。8c对较不理想的目标COX-1的抑制作用更强,IC50 = 7.7 µM。Surflex对接程序预测,化合物(7a)的更稳定的反构象异构体与5-LOX的活性位点形成了良好的络合物,但与COX-1的活性位点没有关系。这与8c的绑定模式相反,
