Overview
The Shoichet lab seeks to bring chemical reagents to biology,
combining computation and experiment. In a protein-centric
approach, molecular
docking, we discover new ligands that complement protein
structures. Using
a ligand-centric
approach, we discover new targets for known drugs and
reagents. A focus for both is the discovery of reagents to
modulate G-Protein Coupled Receptors (GPCRs).

To support our research we have had to develop and optimize chemical library, docking, and chemoinformatics tools. These we have made freely available to the community:
- The ZINC database of commercially available, dockable molecules.
- The DUD-E benchmark of 102 targets, 30,000 ligands & 1.5 Million decoys.
- DOCK Blaster, a web-based community tool for docking.
- An Excipients Database of FDA-approved drug excipients, their properties, sources, and activities.
- SEA, a chemoinformatics method for predicting targets for ligands.
We are grateful to the NIGMS, the NIH office of the Director, and the US FDA for financial support. We thank and OpenEye Scientific Software for software.
