Chemical Discovery (CHEM) Award (R21/R33) -- AIDS

Funding Agency:
National Institutes of Health

The purpose of this FOA is to support the development of chemical probes that aid basic research investigations on substance use disorders (SUDs) or identify new lead chemical scaffolds with potential for structure activity relationship (SAR) studies on SUDs. In the long term, it is hoped that these lead chemical scaffolds will provide a greater number of pharmacological tools for basic research and possible drug candidates for medications development.
