inhibit p38 MAPK, the treatment of javamide-II-ethyl and -methyl esters could suppress the production of IL-8 and MCP-1 protein significantly by 22-73% (p < 0.05) in the differentiated THP-1 cells, and the inhibition was slightly stronger by the ethyl ester than the methyl ester. Altogether, this study suggests that javamide-II-O-ethyl ester may be a most potent p38 MAPK inhibitor among the tested compounds
p38丝裂原激活的蛋白激酶(p38 MAPK)是一种关键的蛋白激酶,与炎症/应激相关疾病的进展密切相关。我们的数据表明,javamide类似物可能具有很强的抗炎活性,但有关其对p38 MAPK的影响的信息很少。因此,在本文中,使用计算机筛选和体外p38 MAPK测定方法研究了三十种javamide类似物对p38 MAPK的影响。合成了javamide类似物,并使用核磁共振(NMR)光谱法确定了其化学结构。然后,使用计算机模拟程序筛选javamide类似物。筛选出的类似物表现出广泛的结合能(ΔE; -20至-39)和几种具有ΔE的类似物。-34至-39显示出与p38 MAPK的强结合亲和力。在体外p38 MAPK分析中,该激酶被具有高结合能(ΔE; -34至-39)和计算机模拟评分(Avg。评分; -27.5至-29.3)的类似物显着抑制。此外,两种检测方法的比较分析显示计算机模拟评分与p38
