Snake Venoms in Drug Discovery

Animal venoms for defense and predation are not a single toxin but are instead a complex mix of components (proteins, peptides, and enzymes) with specific biological and pharmacological activities. New drug development is one of the greatest challenges in the pharmaceutical industry today, and animal venoms have emerged as a source of therapeutic drugs. Over the past 75 years, potential therapeutic agents have been extracted and isolated from the toxins of plants, animals, and microorganisms, and in the past few decades several drugs have been isolated or derived from snake venom proteins.
