Syntheses and structure–activity relationships for some triazolyl p38α MAPK inhibitors
摘要:
The design, synthesis and biological evaluation of novel triazolyl p38 alpha MAPK inhibitors with improved water solubility for formulation in cationic liposomes (SAINT-O-Somes) targeted at diseased endothelial cells is described. Water-solubilizing groups were introduced via a 'click' reaction of functional azides with 2-alkynyl imidazoles and isosteric oxazoles to generate two small libraries of 1,4-disubstituted 1,2,3-triazolyl p38 alpha MAPK inhibitors. Triazoles with low IC50 values and desired physicochemical properties were screened for in vitro downregulation of proinflammatory gene expression and were formulated in SAINT-O-Somes. Triazolyl p38 alpha MAPK inhibitor 88 (IC50 = 0.096 mu M) displayed the most promising in vitro activity. (C) 2014 Elsevier Ltd. All rights reserved.

palladium complexes featuring electronically modified, imidazole-based abnormalN-heterocycliccarbene (aNHC) ligands have been prepared in the hopes of accessing a new class of cationic aNHC ligands electronically distinct from normal NHCs and aNHCs. These palladium complexes represent the first examples of transition metal-ligated aNHC complexes featuring a cationic moiety adjacent to the abnormal carbene
