  Identification of Regioisomers in a Series of N-Substituted Pyridin-4-yl Imidazole Derivatives by Regiospecific Synthesis, GC/MS, and ¹H NMR

  摘要：

  The regiospecific synthesis of 2a (Scheme 3), a novel and potent pyridinyl imidazole inhibitor of p38 MAP (mitogen-activated protein) kinase, and the regioselective preparation of its regioisomer 2b (Scheme 4) are described. Chromatographic and spectroscopic data are presented, which in this class of compounds allow the unambiguous identification of regioisomers prepared by a nonregiospecific synthetic strategy. Biological data demonstrating the importance of the correct regiochemistry for inhibition of p38 are given.

  Tetra-substituted imidazoles were designed as dual inhibitors of c-Jun N-terminal kinase (JNK) 3 and p38α mitogen-activated protein (MAP) kinase. A library of 45 derivatives was prepared and evaluated in a kinase activity assay for their ability to inhibit both kinases, JNK3 and p38α MAP kinase. Dual inhibitors with IC50 values down to the low double-digit nanomolar range at both enzymes were identified

  The anti-inflammatory potential of p38 mitogen-activated protein kinase (MAPK) inhibitors was coincidentally expanded to a dual inhibition of p38 alpha MAPK and phosphodiesterase 4 (PDE4), and the potential benefits arising from the blockage of both inflammation-related enzymes were thoroughly investigated. The most promising compound, CBS-3595 (1), was successively evaluated in in vitro experiments as well as in ex vivo and in vivo preclinical studies after administration of 1 to rodents, dogs, and monkeys. The resulting data clearly indicated a potent suppression of tumor necrosis factor alpha release. For reconfirming the findings of the animal studies when administering 1 to healthy human volunteers, a phase I clinical trial was conducted. Apart from further information regarding the pharmacokinetic and pharmacodynamic characteristics of 1, it was demonstrated that dual inhibition of p38 alpha MAPK and PDE4 is able to synergistically attenuate the excessive anti-inflammatory response.

  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.
