Venom Peptides and their Mimetics as Potential DrugsOren Bogin, Ph.D. Venomous creatures have a sophisticated mechanism for prey capture which includes a vast array of biologically-active compounds, such as enzymes, proteins, peptides and small molecular weight compounds. These substances target an immense number of receptors and membrane proteins with high affinity, selectivity and potency, and can serve as potential drugs or scaffolds for drug design.
