Abstract
In this work, we describe the original characterization of peptides and proteins present in the skin secretions of the Mexican amphibian Hyla eximia. To this purpose, a novel water/dark extraction method, as well as the classic electrical stimulation procedure, was applied in order to extract the skin secretion. Two novel antimicrobial peptides He-1 and He-2 were sequenced. In addition, a molecular mass fingerprint revealed more than one hundred different molecules. Eight peptides in homogeneous form were assayed against five species of bacteria. Thereafter, the peptide He-2 demonstrated high antiparasitic activity against ookinete forms of malaria parasites at low concentration.
