GRI Compound Library It’s NOT just a numbers game – compound selection can greatly enhance screening efficiency Originally from P&G Pharma and represents a $22M investment Selected based on drug-like properties and to maximize structural diversity within a 6-dimensional “drug-like” space Both external (commercial suppliers) and internal discovery and combinatorial chemistry programs used as sources ~250,000 compounds Software to rapidly expand around structural leads identified Vendor Database Remove duplicates Remove reactives, Unusual groups, & toxicophores (80 substructures) MW filter Solubility Filter Lipinski Rule of Five > 5 H-bond donors MW < 500 c log P < 5  N's + O's < 10 “Cleaned” database 26 databases >4 million structures

Compounds Selected for Repository Defined by experienced medicinal chemists Broad, uniform distribution across Drug Space with concentrations of density in key areas from directed purchase and in house synthesis. Compare to 5 vendor screening collections 3,000 to 500,000 compounds 27% - 56% of vendors’ compound collections do NOT meet criteria for drug-like UC Compound collection is 2X to 100X more chemically diverse across Drug Space. Vendor Libraries are inherently predisposed to clustered groupings. We picked the best, most relevant compounds from each.

Molecular Modeling & Virtual Screening Protein – Ligand Docking Rapid docking algorithms for high volume virtual screening of drug targets against all commercially available compounds Detailed dynamic follow-up docking for enhanced accuracy and prediction of binding interactions. Pharmacophore Modeling Abstracting key pharmacophoric elements from molecular series, and using this as the basis for virtual screening. Nearest-Neighbor Analysis (hit expansion) Shape matched and general similarity based methods to identify compounds similar to leads.
