The Program that this Announcement describes is one component of the NIH Roadmap Molecular Libraries and Imaging Initiative. It provides $100K of funding in Year 1 (via the R21 mechanism) to develop and characterize assays to novel targets, pathways and cellular phenotypes that can be miniaturized and automated. The objective of the Program is to develop assays that can be used to identify small molecule interactions via high-throughput screening (HTS) of small molecular compound libraries, and to chemically optimize these active compounds as molecular probes. For this reason, the Program provides rapid “Fast-Track” access, and $25K of additional funding, for HTS-ready assay projects that enter the Roadmap Molecular Library Screening Center Network (MLSCN) in Year 2 of the award.
All applications should provide a rationale for how the availability of a small molecule molecular probe would add a pharmacological dimension to their work that is not currently possible. In addition, Investigators should define the attributes to be captured in the design of this probe, and provide a plan for developing and characterizing assays that could be used to identify small molecules with essential probe attributes from a large diversity collection of >300,000 small molecules. Emphasis will be placed on the screening of targets for which selective and potent small molecule modulators are not currently available.
Particularity of the program
The overall goal of the Roadmap Molecular Library Initiative is to promote the development of small molecule pharmacological tools, and to also facilitate the creation of a PubChem database matching biological assays (for targets, pathways or phenotypes) to small molecules that have activity in these assays. This is being accomplished through the creation of the MLSCN, a national network of 10 high-throughput Screening Centers.
The Assay Development for HTS Program described by PAR-08-024 provides the funding necessary to translate assays from the lab bench into formats that can be used by the MLSCN Centers, and thus acts to promote the first necessary step required for molecular probe development.
It is expected that 40-50 assay development projects will be funded (for $8 million), in response to two receipt dates each year for the Assay Development for HTS Program.
