| Outline of Final Research Achievements |
Phosphonyl and phosphinyl functionalities have been utilized as phosphate mimetics and a bioisostre of carboxylic acids to discover biologically active compounds. In this project, several methods for synthesis of novel phosphonate and phosphinate derivertives have been developed.
A novel series of phosphonate esters was synthesized on the basis of our previously developed aryl carboxylate-type tryptase selective inhibitor. The potency of these synthesized compounds was assessed with an enzyme inhibition assay using three available serine proteases. The phosphonate derivative showed potent thrombin inhibitory activity, whereas it exhibited no or only weak tryptase and trypsin inhibition. The inhibition pattern against thrombin with developed compound is non-competitive in spite of the fact that the lead carboxylate compound is competitive inhibitor.
