Inhibition of trypsin (By similarity). Has anticarcinogenic activity, prevents transformation of DMBA-treated JB6 cells. Has antipromoter activity, prevents promotion by tetradecanoyl phorbal acetate (TPA) in JB6 cells. Prevents tertiary butyl hydroperoxide-induced mutagenesis. Protects AT base pairs and shows antimutagenesis activity in TA102 and TA104 S.typhimurium mutagenesis tests. Inhibits paw edema formation induced by phospholipase A2 in Swiss Wistar mice. Prevents the release of arachidonate, the parent compound for the synthesis of prostaglandins and prostacyclins. Has antimalarial activity, kills P.falciparum. Has antivenom activity, nullifies the lethal effects of N.naja venom and inhibits phospholipase A2 present in N.naja venom. Has antifungal activity, inhibits cilia formation by A.niger. Is not toxic or allergenic. Stable for 7 days at room temperature and for 30 days at 4 degrees Celsius. Remains active after incubation at 100 degrees Celsius for 3 hours. The N-terminus is blocked. Belongs to the protease inhibitor I3 (leguminous Kunitz-type inhibitor) family. The order of the first peptide shown is unknown.
