RESUMEN
The design, synthesis and biological evaluation of novel triazolyl p38α 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 p38α 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 p38α MAPK inhibitor 88 (IC50=0.096 µM) displayed the most promising in vitro activity.
