l)salicylic acids (14a and 14b) were completely non-ulcerogenic since no gastric lesions were present (UI = 0) relative to aspirin (UI = 57) at an equivalent μmol/kg oral dose. The N-difluoromethyl-1,2-dihydropyridin-2-one moiety provides a novel 5-LOX pharmacophore for the design of cyclic hydroxamic mimetics for exploitation in the development of dual COX-2/5-LOX inhibitory AI drugs.
一类新的水杨酸和的ñ -乙酰基-2- carboxybenzenesulfonamide具有一个区域异构体Ñ附连到其C-4或C-5位上二氟甲基-1,2-二氢吡啶-2-酮药效被设计用于评价作为抗炎(AI)代理商。用N-二氟甲基-1,2-二氢吡啶-2-酮部分取代二氟菊酯中的2,4-二氟苯环,可提供显示出双重选择性环加氧酶2(COX-2)/ 5-脂氧合酶(5-LOX)抑制性的化合物活动。AI结构活性研究表明,C-4(14a)和C-5(14b)水杨酸酯区域异构体的效力分别比阿司匹林和C-5 N-乙酰基-2-羧基苯磺酰胺区域异构体(1.4-1.6倍)强。22b)的效力分别比布洛芬和阿司匹林高1.3倍和2.8倍。体内溃疡指数(UI)研究表明4-和5-(N-二氟甲基-1,2-二氢吡啶-2-一-4-基)水杨酸(14a和14b)完全无溃疡性,因为没有胃相对于阿司匹林(UI = 57)而言,当量口服剂量为μmol/
