The search of new molecules presenting pharmacological activities is constantly increasing, especially because pathogenic microorganisms are becoming resistant against antibiotics. As an alternative, researchers are studying animals, plants or microorganisms, trying to find new molecules to fight microbial infections. Following the discovery of the antimicrobial peptides present in skin secretion from the frog Xenopus laevis, in 1987, the search for new molecules with these characteristics was intensified in others amphibians. Thus, due to the evolutionary relationship with X. leavis, the study of the frog Pipa carvalhoi is proposed in this project, aiming to isolate and biochemically characterize molecules that could present potential antimicrobial activities, given the unusual characteristic of females of this species that take care of their offspring, incubating the eggs and carrying tadpoles on the dorsal skin of their bodies.
