title: Structure-based virtual screening for low molecular weight chemical starting points for dipeptidyl peptidase IV inhibitors.
abstract: Structure-based virtual screening was performed against the target dipeptidyl peptidase IV (DPP-IV) to identify good chemical starting points for medicinal chemistry. A database of available compounds was filtered by calculated physical properties and undesired chemistry. This database was matched against two in-house designed DPP-IV pharmacophores, and the hits from these pharmacophore searches were docked into a DPP-IV crystal structure. Compounds were then selected for testing and 51 active compounds were identified from a list of 4000 compounds tested. These had activities ranging from 30% to 82% when tested at a concentration of 30 microM in an enzyme inhibition assay.
