A series of novel 1,2,3,5-tetrahydroimidazo[2,1-b]quinazolin-2-one derivatives substituted with a secondary amino group has been prepared and tested for the activities of inhibitingplateletaggregation in rats in vitro and ex vivo. Most of the compounds were found to be the potentinhibitors of plateletaggregation. Some of the active compounds were soluble in water and effective via iv infusion in

A series of dual OX(1)R/OX(2)R orexin antagonists was prepared based on a N-glycine-sulfonamide core. SAR studies of a screening hit led to compounds with low nanomolar affinity for both receptors and good oral bioavailability. One of these compounds, 47, has demonstrated in vivo activity in rats following oral administration. (C) 2008 Elsevier Ltd. All rights reserved.
