[Research progress on medicinal values of scorpion venom components].

For thousands of years, scorpions and their venoms have been applied in traditional medicine in China to treat a variety of difficult miscellaneous diseases. The venom is a complex mixture of bioactive molecules, such as peptides and proteins (e.g. neurotoxins). Among them, neurotoxins (named scorpion toxins) are the most important bioactive components. Up to now, more and more characterized venom components have been isolated from different scorpions, providing numerous candidate molecules for drug design and development. Many investigations have shown the potent effects of venom or its components against the nervous, immune, infection, cardiovascular and neoplastic diseases. Moreover, the scorpion toxins could be used as molecular backbone to develop new specific drugs based on their unique structures and functions. In this review, we focus on the medicinal values and the possible mechanisms of scorpion toxins with promising medicinal prospect against the relative diseases, providing the data basis for further development of relative drugs.
