Norsanguinarine has antifungal activity, it exhibits 100 % inhibition of A. brassicicola and C. maculans at 1000 ppm whereas. It shows significant cytotoxic activities (ED (50) values < 4 microg/ml) against P-388, KB16, A549, and HT-29 cell lines.

Cell-permeable calmodulin (CaM) agonist that binds to the EF-hand/Ca2+-binding site; produces CaM-dependent activation of phosphodiesterase. Also binds to cytoplasmic sites on other Ca2+ channels, including NMDA and HIV-1 gp120-activated channels, inhibiting Ca2+-mediated cytotoxicity and apoptosis (IC50 = 52 μM). Shown to protect pancreatic acinar cells from gossypol induced necrosis. Inhibits VLA-5-mediated adhesion of mast cells to fibronectin in vitro and attenuates inflammatory cell influx in guinea pig lung in vivo.
