Skin secretions of amphibia of the Bombina genus contain two families of antimicrobial peptides, the bombinins (bombinin-like peptides) and the bombinins H (H for hydrophobic and hemolytic). The latter family includes a number of peptides containing a D-amino acid in the second position, in addition to their corresponding all L-isomers. The antimicrobial activity of three pairs of bombinin H isomers, H2/H4, H6/H7 and GH-1D/GH-1L, has been investigated. The first two pairs of peptides were actually isolated from the secretion, whereas the third was synthesized according to the sequence deduced from a gene coding for a bombinin-like peptide in Bombina orientalis.
