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.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
