| Outline of Final Research Achievements |
We conducted basic research aiming at elucidating the inhibitory molecular mechanism of phosphonate compounds which show inhibitory activity only to thrombin among serine proteases, and also bind to sites different from the substrate binding site to show inhibitory activity. The conversion of the phosphonate site of the present compound to the carboxylate show competitive type inhibition and the enzyme selectivity decreases. This phenomena is a very interesting because the inhibition mode shows quite different only converted carbonyl group to phosphoryl group. However, the present compounds since strength and enzyme selectivity of the activity was not sufficient, in the present study were subjected to structural development was oriented to improve the activity and selectivity. As a result, various valuable information to increase the inhibition ability and enzyme selectivity was obtained.
