Scripps research scientists develop brand new class of small molecules through innovative chemistry
Date:11/20/2011

JUPITER, FL -- Inspired by natural products, scientists on the Florida campus of the Scripps Research Institute have created a new class of small molecules with the potential to serve as a rich foundation for drug discovery.

Combining the power of synthetic chemistry with some advanced screening technologies, the new approach could eventually expand by millions the number of provocative synthetic compounds available to explore as potential drug candidates. This approach overcomes substantial molecular limitations associated with state-of-the-art approaches in small molecule synthesis and screening, which often serve as the foundation of current drug discovery efforts.

The study, led by Scripps Research Associate Professor Glenn Micalizio, was published Nov. 20, 2011, in an advanced online edition of the journal Nature Chemistry.

To frame the significance of this advance, Micalizio explains that high-throughput screening is an important component of modern drug discovery. In high-throughput screening, diverse collections of molecules are evaluated en masse for potential function in a biological area of interest. In this process, success is critically dependent on the composition of the molecular collections under evaluation. Modern screening centers maintain a relatively static collection of molecules, the majority of which are commercially available materials that have structures unrelated to natural products -- molecules that are appreciated as validated leads for drug development.

"This divergence in structure between natural products and commercially available synthetics lies at the heart of our inquiry," said Micalizio. "Why should we limit discovery of therapeutic leads to compound collections that are influenced by concerns relating to commercial availability and compatibility with an artificial set of constraints associated with the structure of modern screening centers?"
