In order to study the anti-inflammatory activity of novel 6-substituted and 6,9-disubstituted purine derivatives, 20 compounds, L1–10 and W1–10, derived from purine and lacking a gold complex were designed, synthesized and their anti-inflammatory activity was screened. LPS-induced TNF-α, IL-1β, IL-6, PGE2, NO, COX-2 and iNOS mRNA were evaluated, and western blot and NF-κB p65 translocation assay were
为了研究新型6取代和6,9-二取代嘌呤衍生物的抗炎活性,设计,合成了20种衍生自嘌呤且缺乏金配合物的化合物L1-10和W1-10,它们的抗炎作用筛选炎症活动。评价LPS诱导的TNF-α,IL-1β,IL-6,PGE2,NO,COX-2和iNOS mRNA,并在RAW 264.7巨噬细胞中进行western blot和NF-κBp65易位测定。此外,在小鼠中进行了角叉菜胶诱导的后爪水肿实验。化合物L1,L4,W2和W4对RAW 264.7巨噬细胞中LPS诱导的TNF-α,IL-1β,IL-6和PGE2释放具有明显的剂量依赖性抑制作用。此外,这些化合物在同一细胞中强烈抑制LPS诱导的NO,COX-2和iNOS mRNA。体内抗炎活性测试结果表明,L1和L4在给药后2至5小时比已知的消炎药Au(L 3)(PPh 3)更有效,而W4在给药后3至5小时最有效。因此,W2,W4和L1,L4可以在体外和
