NuP-3 — Datasheet

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.

Published experimental findings depend on the model and assay conditions. They do not guarantee equivalent performance in every application. For laboratory research use only.
