In this work, a serie of cyclocoumarol derivatives was designed, synthesized, characterized and studied for their potentialities as selective inhibitors of COX-2. All target compounds have been screened for their anti-inflammatory activity by the assay of PGE2 production. Among them, compound 5d exhibited the most potent inhibitory activity with a PGE2 inhibition compared to NS-398 (79% and 88% respectively)
在这项工作中,设计,合成,表征和研究了一系列环香豆酚衍生物作为COX-2选择性抑制剂的潜力。已经通过测定PGE 2的产生筛选了所有目标化合物的抗炎活性。其中,与NS-398(分别为79%和88%)相比,化合物5d表现出对PGE 2的抑制作用最强,并且对COX-1酶表现出非抑制作用。对接研究揭示了该化合物占据选择性COX-2腔的能力,从而在甲氧基的氧与酶结合位点的His90和Arg513之间建立了额外的氢键。
