Inhibition of plasminogen activator inhibitor (PAI)-1 is useful to treat several disorders including thrombosis. An inhibitor of PAI-1 (TM5275) was newly identified by an extensive study of structure-activity relationship based on a lead compound (TM5007) which was obtained through virtual screening by docking simulations. Its antithrombotic efficacy and(More)
Small molecule inhibitors of plasminogen activator inhibitor (PAI)-1 have been reported to date but their clinical effects still remain unknown. The present study was undertaken to investigate the structure-activity relationships (SAR) of newly synthesized 2-acylamino-3-thiophenecarboxylic acid dimers based upon a core structure of TM5001 (1) and TM5007 (2)(More)
Novel anthranilic acid derivatives having substituted N-acyl side chains were designed and synthesized for evaluation as plasminogen activator inhibitor-1 (PAI-1) inhibitors. Compounds with a 4-diphenylmethyl-1-piperazinyl moiety on the acyl side chains in general exhibited potent in vitro PAI-1 inhibitory activity and good pharmacokinetic profiles after(More)
