Is cytotoxic against human non-small cell lung adenocarcinoma A-549 cells (LC(50)=56 ug/ml), breast adenocarcinoma MDA-MBsy-231 cells (LC(50)=62 ug/ml) and colorectal adenocarcinoma HT-29 cells (LC(50)=110 ug/ml). Shows low hemolytic activity against human erythrocytes (LC(50)>600 ug/ml). Is also cytotoxic against human umbilical vein endothelial HUVEC cells (57 ug/ml) indicating no differential activity against cell lines derived from neoplastic tissues. Expressed by the venom gland. LD(50) is 40 +/- 3 mg/kg by intravenous injection into mice. Does not inhibit growth of reference strains of E.coli or S.aureus (MIC values >200 ug/ml). Belongs to the snake three-finger toxin family. Short-chain subfamily. Orphan group X sub-subfamily.
