NuP-3

Biological Activity

NuP-3 is a potent and selective MAPK13 and MAPK14 inhibitor (IC50 of 7 nM and 14 nM, respectively) that effectively targets respiratory inflammation and mucus overproduction. In human tracheal epithelial cell (hTEC) cultures, it markedly inhibits IL-13-induced MUC5AC and CLCA1 expression without causing cell toxicity, showing superior efficacy compared to the MAPK14 inhibitor NuP-43. Beyond its success in minipig models of airway disease and viral infection, NuP-3 also down-regulates biomarkers associated with basal-epithelial stem cell activation, demonstrating its role as a precise upstream therapeutic agent for chronic lung conditions.
