Comments Information

    • Function

    • Disrupts biological membranes, particularly those rich in phosphocholine. Has antimicrobial activity against Gram- negative bacterium E. coli and the Gram-positive bacteria B. subtilis and S. aureus, and hemolytic activity against sheep red blood cells. Has insecticidal activity against S. frugiperda ovarian cells by opening non-selective ion channels. Enhances the insecticidal activity of spider venom neurotoxic peptides.
