Antimicrobial peptides are produced by plants and most organisms throughout the animal kingdom including humans. Antimicrobial peptides protect against a broad range of infectious agents, as bacteria, fungi, and viruses. The amphibian skin is an especially rich source of antimicrobial peptides. See also the product families: Hepcidins LL-37 and Fragments Tuftsin and Analogs (subfamily).

The cecropins are a group of antibacterial peptides that were first isolated from the hemolymph of the giant silk moth Hyalophora cecropia.

Cecropin P1 (SWLSKTAKKLENSAKKRISEGIAIAIQGGPR), a homolog of insect cecropins isolated from pig intestine, was thought to be the first mammalian antimicrobial peptide. Later studies showed that the peptide is produced by the intestinal parasitic nematode Ascaris suum. The 31 amino acid peptide is highly potent against Gram-negative bacteria but has a reduced activity against Gram-positive bacteria. A disruptive effect on bacterial membranes has been proposed as mechanism of antimicrobial activity.
