Echis carinatus venom toxins

Echis carinatus venom toxins represent a complex mixture of bioactive proteins and peptides derived from the saw-scaled viper, one of the most medically significant snakes globally (WHO, 2016). These toxins primarily include snake venom metalloproteinases (SVMPs), serine proteases, disintegrins, and phospholipases A2, which collectively disrupt the hemostatic system and cause local tissue destruction (PubMed: 22306005). A hallmark of this venom is the presence of procoagulant enzymes like ecarin, which converts prothrombin to meizothrombin, leading to venom-induced consumption coagulopathy (UniProt: P81105). In clinical medicine, these toxins are the primary targets for antivenom therapy, which utilizes equine or ovine antibodies to neutralize their toxic effects (StatPearls: Snake Envenomation). Furthermore, specific components like echistatin have served as structural templates for the development of antiplatelet drugs like tirofiban, while small molecule inhibitors like varespladib are being investigated to target the phospholipase A2 components (PubMed: 32634414).
