Stress-induced p38α mitogen-activated protein (MAP) kinase activation modulates cytokine overproduction and is associated with neuroinflammation and neurodegeneration. As a potential therapeutic approach, novel Skepinone-based p38α MAP kinase inhibitors were optimized to cross the blood–brain barrier via either amino acid transporters or hydrophobic diffusion. To enhance absorption from the oral route
应激诱导的 p38α 丝裂原活化蛋白 (MAP) 激酶激活调节细胞因子过度产生,并与神经炎症和神经变性有关。作为一种潜在的治疗方法,基于 Skepinone 的新型 p38α MAP 激酶抑制剂经过优化,可通过氨基酸转运蛋白或疏水扩散穿过血脑屏障。为了增强口服途径的吸收,我们使用了活性羧基类似物的甲酯前药。其中,3-(8-((2,4-二氟苯基)氨基)-5-oxo-10,11-dihydro- 5H - dibenzo[ a , d ][7]annulene-3-carboxamido)propanoic acid ( 43 ; p38α, IC 50 = 5.5 nM) 和 4-(8-((2,4-二氟苯基)氨基)-5-oxo-10,11-dihydro-5 H -dibenzo[a , d ][7] annulene-3-carboxamido)butanoic acid ( 44 ; p38α
