Résumé
Snake bite is a common acute and severe disease in tropical and subtropical regions, and its public health importance has been largely neglected. Snake venom is a complex mixture of active proteins, polypeptides, and other toxins. Many of these components can target multiple ion channels, cell receptors, and membrane transporters. Compared with traditional small molecule drugs, the proteins and polypeptides from snake venom have stronger specificity and affinity to targets and are especially suitable for novel drug design. The current studies show that snake venom and its components have great potential for development as leading compounds of new drugs. In this paper, the recent advances in main components, toxic effects, and detoxification strategies of snake venom, as well as its pharmacological activities and medical application are reviewed. The aim is to provide reference for clinical diagnosis and treatment of snake bite and development of new drugs based on snake venom.
