title: Combinatorial peptide libraries in drug design: lessons from venomous cone snails.
abstract: Many present-day drugs are derived from compounds that are natural products, a traditional source of which is fermentation broths of microorganisms. The venoms of cone snails are a new natural resource of peptides that may have a pharmaceutical potential equivalent to those from traditional sources, particularly for developing drugs that target cell-surface receptors or ion channels. In effect, cone snails have used a combinatorial library strategy to evolve their small, highly bioactive venom peptides. The methods by which the snails have generated thousands of peptides with remarkable specificity and high affinity for their targets may provide important lessons in designing combinatorial libraries for drug development.
