BMAP-27
BMAP-27 is a cationic amphipathic α-helical antimicrobial peptide with anticancer activity. BMAP-27 disrupts the integrity and permeability of cell membranes, leading to the leakage of intracellular DNA, proteins and alkaline phosphatase. BMAP-27 increases intracellular ROS levels and reduces plasma endotoxin and TNF-α concentrations. BMAP-27 can be used in studies related to Salmonella infection, breast cancer, lung cancer and obstructive jaundice.

Activité biologique
BMAP-27 (2-4 μM) potently inhibits the growth of S. aureus and E. coli with MIC values of 2-4 μM[2].
BMAP-27 (2-5 μM; 20-60 min) rapidly kills S. aureus and E. coli, achieving near-complete bacterial death within 20 min at its MIC of 2 μM[2].
BMAP-27 efficiently depolarises the cytoplasmic membranes of S. aureus and E. coli at concentrations lower than its MIC of 2-4 μM[2].
BMAP-27 (2 days) exhibits strong dose-dependent cytotoxicity against human MDA-361 and A549 cancer cells, with IC50 values lower than its haemolytic activity IC50[2].
BMAP-27 (1 h) exhibits moderate dose-dependent haemolytic activity against human red blood cells[2].
BMAP-27 (5-32 μM; 2-5 min) potently disrupts anionic POPC/POPG (2:1) membranes, shows moderate disruption of zwitterionic POPC/cholesterol (4:1) membranes at high concentrations, and exhibits Phosphatidylserine (PS) (HY-A0183)-dependent membrane disruption that correlates with its anticancer activity[2].
