  新型取代的吡啶基咪唑类作为有效的抗细胞因子药物，对肝细胞色素P450酶的活性较低。

  摘要：

  制备了一系列p38 MAP（有丝分裂原活化蛋白）激酶的多取代吡啶-4-基咪唑抑制剂，作为小分子抗细胞因子药物和候选药物，用于治疗慢性炎性疾病。评估了吡啶基和咪唑部分的取代基对选择性抑制p38的贡献，而没有伴随的细胞色素P450相互作用。将1-苯基乙基（7e，p38：IC（50）0.38 microM）或乙酰基取代基放置在几个2-氨基吡啶咪唑的环外氮原子上导致鉴定出有效的p38抑制剂，该抑制剂超过了起始铅ML 3375（p38：IC （50）0.63 microM）效能。初步的模型研究将7e的增强生物活性与其1-苯基乙基氨基侧链和靠近p38接头区域的疏水口袋之间的新型相互作用相关。该系列中最活跃的p38抑制剂在功能性PBMC（外周血单个核细胞）和全血测定中保持了其功效。此外，与在模型p38抑制剂中观察到的肝毒性有关的细胞色素P450相互作用，通过在咪唑核的1位上引入四甲基哌啶取代基而非常有效

  Tetrasubstituted Imidazole Inhibitors of Cytokine Release:  Probing Substituents in the N-1 Position

  摘要：

  We prepared novel 1,2,4,5-tetrasubstituted imidazole derivatives with high anti-inflammatory activity by using our previously described regiospecific synthesis. Systematic optimization of the imidazole N-1 substituent resulted in compound 9b that potently inhibited the mitogen-activated protein kinase p38 (p38 IC50 = 0.218 muM) as well as the release of the proinflammatory cytokines interleukin-1beta (IL-1beta) and tumor necrosis factor alpha. (TNFalpha) from human whole blood after stimulation with LPS. Furthermore, compound 9b exhibited reduced cytochrome P450 interaction in comparison with SB203580. This result is particularly important, since cytochrome P450 interaction is observed for some p38 inhibitors and in turn can potentially cause drug-drug interaction or lead to other hepatic changes such as P450 enzyme induction.

  been linked to the liver toxicity observed for model p38 inhibitors, was very efficiently reduced through introduction of a tetramethylpiperidine substituent at the 1 position of the imidazole nucleus. Combination of both structural features provided 14c (p38: 0.34 microM, inhibition of CYP1A2 0%, 2C9 2.6%, 2C19 7.6% at 10 microM), which was selected for further development.
