A new fragment-basedmethod for the rapid development of novel and distinct classes of nonpeptidic protease inhibitors, SubstrateActivityScreening (SAS), is described. This method consists of three steps: (1) a library of N-acyl aminocoumarins with diverse, low molecular weight N-acyl groups is screened to identify protease substrates using a simple fluorescence-based assay, (2) the identified N-acyl

aggregation, and antagonists at these receptor subtypes have antithrombotic properties. In an earlier publication, we have characterized the SAR as P2Y(1) receptor antagonists of acyclic analogues of adeninenucleotides, containing two phosphate groups on a symmetrically branched aliphatic chain, attached at the 9-position of adenine. In this study, we have focused on antiaggregatory effects of P2Y antagonists

induced by the interactions between angiotensinII (AII) and both AT1 and AT2 receptors, we have pursued the discovery of orally active non-peptide AII antagonists that exhibit potent and equal affinity for human AT1 and AT2 receptor subtypes. A series of previously prepared nanomolar (IC50) trisubstituted 1,2,4-triazolinone biphenyl-sulfonamide dual-acting AII antagonists has been modified at five different
We report an efficient palladium-catalyzed approach to the synthesis of benzoxazole derivatives via sequential heteroarylation/acylation reaction of iodobenzenes. Three readily available starting materials, iodobenzenes, anhydrides, and benzoxazoles, were smoothly coupled to form new C–C bonds at the ortho and ipso positions of the iodobenzenes to afford 2-heteroaryl-3-acylbenzene derivatives in good
products and the compounds are also useful chiral buildingblocks for further synthetic endeavours. Highly enantioselective desymmetrisation of Fittig’s lactones with alcohols is promoted by bifunctional cinchona squaramides. The reactions were carried out with monodeuterated methanol to detect possible hidden racemisation of the stereogenic centre. Current evidence suggests that racemisation was not a
