Cecropin A TFA is a linear 37-residue antimicrobial polypeptide isolated from Hyalaphora cecropia pupae. Cecropin A TFA exhibits anti-bacterial, anti-inflammatory[1] and anti-cancer activity[2].
Cecropin A (10, 20, 30, 40 and 50 μM) induces cytotoxicity on HL-60 cells in a dose-dependent manner. Cecropin A induces apoptosis independent of caspase activation[1].Cecropin A shows good antibacterial activity against both multidrug-resistant Gram-negative bacteria such as A. baumanii (MDRAB) and multidrug-resistant P. aeruginosa (MDRPA) with IC50s of 0.5-1 μM.Cecropin A (0.1, 0.25 μM) exhibits anti-inflammatory activities. Cecropin A (25 μM) effectively suppresses the expression of mTNF-α, mIL-1β, and mMIP-2 mRNA and slightly inhibits the expression of mMIP-1 mRNA. Cecropin A also effectively inhibits LPS-induced phosphorylation of ERK, JNK, p38 MAPK, and reduced the expression of COX-2[2].
