Inhibitors with vicinal 4-fluorophenyl/4-pyridine rings on a five- or six-membered heterocyclic ring are known to inhibit the p38 mitogen-activated protein kinase (MAPK), which is a potential target for rheumatoid arthritis and several different types of cancer. Several substituted azastilbene-based compounds with vicinal 4-fluorophenyl/4-pyridine rings were designed using computational docking, synthesized, and evaluated in a cell-free radiometric p38α assay. The biochemical evaluation shows that the best inhibition (down to 110 nM) is achieved for azastilbene-based compounds having an isopropylamine substituent in the 2-position of the pyridine ring. The inhibition of p38 signaling in human breast cancer cells was observed for two of the compounds.
具有邻位4-氟苯基/4-吡啶环的五元或六元杂环环的抑制剂已知能够抑制p38丝裂原激活蛋白激酶(MAPK),该激酶是类风湿关节炎和几种不同类型癌症的潜在靶点。使用计算对接设计了几种基于取代的氮杂斯蒂本的化合物,这些化合物具有邻位4-氟苯基/4-吡啶环,并进行了合成和无细胞放射性测定的p38α评估。生化评估表明,具有异丙胺取代基的氮杂斯蒂本化合物在吡啶环的2位上显示出最佳抑制效果(降至110 nM)。观察到这两种化合物对人乳腺癌细胞中的p38信号传导的抑制。
