    Product Description

    JCP251 is a protease inhibitor.1 It inhibits neutrophil elastase when used at a concentration of 5 µM and reduces the activity of HIV protease and caspase-3 by 70 and 68%, respectively, when used at a concentration of 100 µM in cell-free assays.1,2 JCP251 decreases amyloid-β (1-40) (Aβ40; Item No. 21617) and Aβ42 (Item No. 20574) levels in HEK293 cells expressing wild-type and Swedish mutant amyloid precursor peptide (APP; IC50s = ~30 µM for both).3

    WARNING This product is not for human or veterinary use.
