Natural Products & Antibiotics

Natural products are chemical compounds or substances produced by a living organism that usually have a pharmacological or biological activity for use in drug discovery. Modern clinically useful natural product-derived drugs include aspirin, quinine, Paclitaxel (Taxol®) and Artemisinin. Microorganisms produce a large variety of antimicrobial agents, and marine organisms have proven a rich source of potent chemicals with inflammatory, antiviral, and anticancer activity. Venoms and toxins often specifically interact with a macromolecular target in the body. As a result, they are important tools in studying receptors, ion channels, and enzymes.

Enzo provides a comprehensive collection of over 800 natural products and rare antibiotics for the drug discovery, diagnostics, and life sciences research market.
