Four scaffolds of varied benzylidene derivatives were synthesized and evaluated as Syk inhibitors for the treatment of rheumatoid arthritis (RA). Among these 31 compounds, 3‐benzylidene pyrrolidine‐2,5‐dione derivatives (including 12k) universally showed good Syk inhibitory activities in the low micromolar to submicromolar range. In the cellular profiling, compound 12k, the most efficient compound
合成了四种不同亚苄基衍生物的支架,并将其作为 Syk 抑制剂用于治疗类风湿性关节炎 (RA)。在这 31 种化合物中,3-亚苄基吡咯烷-2,5-二酮衍生物(包括 12k)在低微摩尔至亚微摩尔范围内普遍表现出良好的 Syk 抑制活性。在细胞分析中,最有效的化合物化合物 12k 对成纤维细胞样滑膜细胞 (FLS)-RA 显示出优异的抗增殖活性,并显示出抑制 IL-6 和 MMP-3 分泌的效力几乎等于 R406(阳性对照) . 尽管比 R406 弱,但 12k 在小鼠胶原诱导关节炎模型中的口服功效是显着的。综合起来,
