evaluated for their anti-inflammatory activity. Ibuprofen, celecoxib and indomethacin were used as standard drugs. All the newly synthesized compounds were in vitro screened for their anti-inflammatory activity adopting 3-(4,5-dimethylthiazol-2-yl)2,5-diphenyltetrazolium bromide dye (MTT), as well as Griess assays. The results showed that all compounds exhibited significant anti-inflammatory activity without
合成了两个源自烟酸支架的创新系列,并评估了它们的抗炎活性。使用布洛芬、塞来昔布和吲哚美辛作为标准药物。采用3-(4,5-二甲基噻唑-2-基)2,5-二苯基溴化四唑染料(MTT)以及Griess试验对所有新合成的化合物进行体外抗炎活性筛选。结果表明,与布洛芬相比,所有化合物均表现出显着的抗炎活性,且不影响巨噬细胞的活力。此外,化合物4d 、 4f 、 4g 、 4h和5b表现出最有效的亚硝酸盐抑制活性,因此具有优异的抗炎活性,MTT结果范围在值86.109±0.51至119.084±0.09之间。与作为参考化合物的布洛芬相比,对 LPS/INF γ 刺激的 RAW 264.7 巨噬细胞中最活跃的化合物进行 TNF-α、IL-6、iNOS 和 COX-2 水平的评估。与布洛芬相比,这五种化合物对这些炎症细胞因子的抑制效力相当。通过角叉菜胶诱导的大鼠关节炎,进一步体内评估了相同化合物的抗炎活性。
