SUMMARY Computational Chemical Biology (CCB) Core will provide comprehensive computational support, including chemical virtual screening, physical property prediction, target validation, hits identification, lead optimization, pharmacophore identification, and pharmacokinetic and dynamic modeling. In addition, the CCB core will provide information management infrastructure supporting the creation and management of scientific data analysis workflows, project reporting, and database management for chemicals including their structures and biological properties. These activities will be fully integrated with projects and with Cores B and D. For example, the analysis of high-throughput screening data and chemical structure-activity relationship data generated by Core B will be stored, indexed, computationally analyzed, and visualized at the CCB Core.
