Frog’s skin secretions are known to present peculiar characteristics involving an arsenal of bioactive molecules. These organisms, in response to stress, injury or predator attack, release a viscous toxic secretion through granular glands containing biogenic amines, alkaloids, steroids, proteins and also peptides. Among such compounds, the antimicrobial peptides (AMPs) are responsible to play an important role in amphibian first-line defense against pathogenic microorganisms such as Gram-negative and positive bacteria, fungi and virus. In amphibians, AMPs have been isolated from different species and functionally studied, presenting not only antimicrobial but also antitumor, antifungal, anti-protozoa and spermicidal activities. However, a large number of AMPs have also shown cytotoxic activities against mammalian cells. In order to develop novel anti-infective drugs with low sid.. View More»
