About this opportunity

The purpose of this Notice of Funding Opportunity (NOFO) is to support investigators who have the interest and capability to join efforts for the discovery of in vivo chemical probes for novel brain targets. It is expected that applicants will have, in hand, the starting compounds (validated hits) for chemical optimization and bioassays for testing new analog compounds.Through this NOFO, NIH wishes to stimulate research in:Discovery and development of novel, small molecules for their potential use in understanding biological processes relevant to the missions of National Institute of Mental Health (NIMH), National Institute on Drug Abuse (NIDA), National Eye Institute (NEI), and/or National Institute on Aging (NIA) andDiscovery and/or validation of novel, biological targets that will inform studies of brain disease mechanisms.Emphasis will be placed on projects that provide new insight into important disease-related biological targets and biological processes.

Portfolio context — this listing covers more than this opportunity

This opportunity is funded under Assistance Listing 93.242 (“Mental Health Research Grants”), a broad federal program that made about 863 new awards per year over the last five fiscal years (median award $552k). Those figures describe that whole portfolio — not this specific solicitation, so we don't show them as if they were this opportunity's track record.

Applicant counts per solicitation are not published by any federal agency — no one can honestly sell you that number. NIH publishes success rates by institute and activity code — source.
