A bioactive peptide QUB-1370 from the frog skin secretion of Pelophylax nigromaculata

Bioactive peptides from amphibian skin secretions have been demonstrated to have multiple biological activities, such as antimicrobial activity, anticancer activity and so on. Furthermore, some of the peptides have been proven as the promising candidates of new drugs.<br>A cDNA precursor encoding the peptide was identified from the skin secretion of Pelophylax nigromaculata by using molecular cloning.

The mature peptide was named QUB-1370 according to its molecular mass. The sequence is: VIPIVSGLLFSLL-NH2. Then the peptide synthesizer was used to synthesis the peptide and the peptide was purified by using RP-HPLC.
