Brevinin-2R is a novel non-hemolytic defensin that was isolated from the skin of the frog Rana ridibunda. It exhibits preferential cytotoxicity towards malignant cells, including Jurkat (T-cell leukemia), BJAB (B-cell lymphoma), HT29/219, SW742 (colon carcinomas), L929 (fibrosarcoma), MCF-7 (breast adenocarcinoma), A549 (lung carcinoma), as compared to primary cells including peripheral blood m...

introduction: antimicrobial peptides as the body's defense strategy play an important role in resistance against infection of microorganism. these peptides are able to modulate the immune and inflammatory processes through the production of defensive molecules. therefore, the modulatory effects of brevinin-2r, an antimicrobial peptide extracted from the skin of the frog (rana ridibunda), w...

b ackground: brevinin-2r, as 25 amino acids peptide of the skin of r ana ridibunda frog, possesses potent antimicrobial and low hemolytic activity. it has an n-terminal hydrophilic region and a c-terminal loop that is delineated by an intra-disulfide bridge. in our study, brevinin-2r and its diastereomer as well  as its  cyclic  analogue  were  synthesized  and  characterized  in  order  to inv...

Brevinin-2R, a member of a new family of antimicrobial peptides isolated from the skin of Rana ridibunda, displays antimicrobial activity against bacteria and fungi. In this study, we have used an assembly PCR method for the fast and extremely accurate synthesis of the brevinin-2R gene. A total of six primers were assembled in a single step PCR, and the assembly was then amplified by PCR to pro...

Antimicrobial peptides are the backbone of first-line defense against various microorganisms in the animal kingdom. Thus, not surprisingly, they are gaining attention in the science and medical fields as a rich repository of new pro-drugs. Below, we focus our attention on the Brevinin family of anuran peptides. While most of them show strong antibacterial activities, some, e.g. Brevinin-2R, app...
