[摘要]：A series of spiroimidazolidinone NPC1L1 inhibitors was discovered by virtual screening of the Merck corporate sample repository using 3D-similarity-based screening. Selection of 330 compounds for testing in an in vitro NPC1L1 binding assay yielded six hits in six distinct chemical series. Follow-up 2D similarity searching yielded several sub-to low-micromolar leads; among these was spiroimidazolidinone 10, with an IC50 of 2.5 mu M. Compound 10 provided a useful scaffold to initiate a medicinal chemistry campaign. (C) 2009 Elsevier Ltd. All rights reserved.
