Research Summary

Mikiko  Sodeoka(D.Phar.)

Our laboratory focuses on the following research areas based on synthetic organic chemistry: 1) development of new reactions and methodologies for the efficient synthesis of bioactive molecules, 2) design and synthesis of molecules having unique biological activity, 3) biological researches using these unique molecules as biological probes. Our research interests encompass from novel synthetic methods using transition metal-catalysts for fluorine-containing molecules and chiral compounds to the design and synthesis of intracellular signal transduction modulators and their application to cell biology research. In particular, we are focusing on enzymes in charge of chemical modification of proteins, such as phosphorylation and methylation. We are working on design and synthesis of selective inhibitors of such enzymes as well as development of new methods for analyzing chemical modification of proteins. Development of new chemical methodology for identification of target protein/binding site of small bioactive molecules and for their imaging. Clarification of the unknown molecular mechanism of cell death (necrosis) by using our original cell death control molecules is also currently underway.
