Organic chemistry focuses on scientific study of the structure, properties, and reactions of organic molecules which contain carbon atoms. In our department, we conduct research in synthetic chemistry, bio-organic chemistry, medicinal chemistry, and enzyme chemistry. Representative research areas include designing and synthesis of catalysts for novel synthetic methodologies, new enzyme inhibitors, intermediates associated to in vivo signal transduction, and physiologically active substances. Furthermore, these methodologies could be applied to the synthesis of complex natural products, bio-active pharmaceuticals, macrocyclic molecules, and industrially & agriculturally useful building blocks.
