Actinins as novel broad-spectrum AMP isolated from the tentacle of Anthozoan Actinia equina (Linnaeus, 1758)

2023

Capturing activities and defense mechanisms of Cnidarian are strongly associated with toxins and peptide with antimicrobial properties. AMP are an important component of many organisms’ innate immune system with a good inhibitory or killing effect against invaders pathogens. We investigated the AMP activity of acid extracts obtained from tentacle and body of Actinia equina (Cnidaria, Anthozoa) against Gram positive (Micrococcus lysodeikticus) and Gram negative (Escherichia coli, Vibrio alginolyticus) bacteria. The peptide fractions showed interesting minimum inhibitory concentrations (MIC) values (concentrations up to 0.125 μg/ml) against tested pathogens. Tentacle acid extracts exhibiting …
