ICB&DD Receives $1.4M Grant

The Institute of Chemical Biology and Drug Discovery (ICB&DD) team, consisting of Subramanyan Swaminathan (PI), Brookhaven National Laboratory Department of Biology; Iwao Ojima (Co-PI), ICB&DD Director; Peter Tonge (Co-I), Department of Chemistry; and Robert Rizzo (Co-I),  Department of Applied Mathematics and Statistics, has received a research consortium grant award from the Defense Threat Reduction Agency, which is part of the Department of Defense. This grant award is for the project “Structure-Based Discovery of Pan-Active Botulinum Neurotoxin Inhibitors.”

Clostridium botulinum neurotoxins (BoNTs) are the most potent toxins known to humans and are considered to be potential biowarfare agents. As a consequence, the Centers for Disease Control has classified these neurotoxins as Category A priority pathogens. The only current treatment for botulism is antibody-based, which will not be effective once the toxin enters the cell. Thus, there is a compelling need to develop novel chemotherapeutics against these neurotoxins.

This multi-disciplinary drug discovery project includes: structure determination of enzyme-inhibitor complexes; virtual screening using DOCK or AUTODOCK to identify small molecules, transition state analogs or peptidomimetics of substrate peptides that can be accommodated in the active site of multiple serotypes; synthesis of novel compounds and further modifications required for a broad spectrum of BoNTs; and enzymology and specific absorption rate for additional compound design.

This exploratory grant award for $1.4 million is for two years, which can be expanded to a larger project grant, and is the first research consortium grant that ICB&DD has received with Brookhaven National Lab.
