Our previous study demonstrated that the secapin peptide from the venom of the Asiatic honeybee (Apis cerana, AcSecapin-1) exhibits anti-fibrinolytic, anti-elastolytic, and anti-microbial activities. In the present study, we investigated the anti-microbial activity and cytotoxicity of a synthetic AcSecapin-1 peptide. Seven synthetic AcSecapin-1 peptides (AcSecapin-S1 to AcSecapin-S7) were synthesized based on the peptide sequence of AcSecapin-1. AcSecapin-S1, which consists of the 25-amino acid sequence identical to that of the mature AcSecapin-1 peptide, exhibited the highest anti-microbial activity against bacteria and fungi. This was followed by AcSecapin-S6, which was missing 10 N-terminal amino acids and 6 C-terminal amino acids from AcSecapinS1. Furthermore, AcSecapin-S1 was not cytotoxic and did not activate macrophages. Taken together, our data demonstrated that a synthetic AcSecapin-1 peptide could exhibit anti-microbial activity without producing a cytotoxic or inflammatory response, suggesting that this synthetic AcSecapin-1 peptide can be used as an anti-microbial agent for biomedical applications.
