The National Institutes of Health (NIH) is offering a funding opportunity for Research Project Grants (R01) aimed at the development of screening assays for drug candidates targeting psychiatric disorders. The primary objectives of this initiative are to stimulate research in the discovery and development of novel small molecules that can potentially treat mental illnesses, as well as to validate compounds that demonstrate desired biological activity through rigorous screening processes. This funding is crucial for advancing therapeutic options for conditions such as depression, schizophrenia, and PTSD, and it encourages applicants to align their proposals with the National Institute of Mental Health (NIMH) priorities. Interested applicants must submit their proposals by May 7, 2026, and can find additional information and application guidelines at the NIH grants website or contact NIH Grants Information at grantsinfo@nih.gov for further inquiries.
