A set of 1,2,4-triazine derivatives were designed as cyclooxygenase-2 (COX-2) inhibitors. These compounds were synthesized and screened for inhibition of cyclooxygenases (COX-1 and COX-2) based on a cellular assay using human whole blood (HWB) and lipoxygenase (LOX-15) that are key enzymes in inflammation. The results showed that 3-(2-(benzo[d][1,3]dioxol-5-ylmethylene)hydrazinyl)-5,6-bis(4-methoxyphenyl)-1
设计了一组1,2,4-三嗪衍生物作为环氧合酶2(COX-2)抑制剂。基于细胞分析,使用人全血(HWB)和脂氧合酶(LOX-15)作为炎症中的关键酶,基于细胞试验合成了这些化合物并筛选了对环氧合酶(COX-1和COX-2)的抑制作用。结果表明3-(2-(苯并[d] [1,3]二氧杂-5-基亚甲基)肼基)-5,6-双(4-甲氧基苯基)-1,2,4-三嗪(G11)为相对于COX-1(50%)被确定为最有效的COX-2抑制剂(78%)。铁还原抗氧化能力(FRAP)分析表明,化合物G10具有最高的抗氧化活性。在LOX抑制试验中,IC50值为124μM的化合物G3是最有效的化合物。进行了分子对接,并且在计算和实验结果之间观察到良好的一致性。
