Alamethicin F50 is a peptaibol isolated from Trichoderma. It is a polymer of 20 amino acids that includes modified and non-proteinogenic amino acids. Alamethicin F50 is a mixture of 13 different peptides, with the most abundant designated as alamethicin F50/5. Alamethicin F50 forms voltage-dependent ion channels in lipid membranes and acts as a lytic agent. It induces lysis of leukocytes (IC50 = 54 and 80 μM for rat mast cells and mouse spleen lymphocytes, respectively) and exhibits antibacterial activity against a panel of 8 mollicutes (MICs = 1.56-12.5 μM).
