Back to Nature: Rethinking Natural Products as Sources of Drug Leads

Overview

Although pharmaceutical companies have highly invested in combinatorial chemistry and high-throughput screening, such approaches have not met initial expectations in their ability to identify new drug candidates. Natural products, which provide qualitatively different chemicals than purely synthetic compounds, could offer a more cost-effective strategy for discovering new drugs.

A January 22, 2008, meeting at the Academy explored the use of natural products as sources for new drugs. High-throughput screening methods and rational drug design with natural products as a starting point has already yielded several druggable lead compounds.
