Harnessing snake venom phospholipases A2 to novel approaches for overcoming antibiotic resistance

Abstract:

The emergence of antibiotic resistance drives an essential race against time to reveal new molecular structures capable of addressing this alarming global health problem. Snake venoms are natural catalogs of multifunctional toxins and privileged frameworks, which serve as potential templates for the inspiration of novel treatment strategies for combating antibiotic resistant bacteria. Phospholipases A2 (PLA2s) are one of the main classes of antibacterial biomolecules, with recognized therapeutic value, found in these valuable secretions. Recently, a number of biomimetic oligopeptides based on small fragments of primary structure from PLA2 toxins has emerged as a meaningful opportunity to overcome multidrug‐resistant clinical isolates. Thus, this review will highlight the biochemical and structural properties of antibacterial PLA2s and peptides thereof, as well as their possible molecular mechanisms of action and …
