Research Areas

This Team focuses on the development of novel types of ligand molecules, which can activate or inhibit the functions of their target proteins, based on synthetic organic chemistry. In particular, the ligand molecules, which interact with proteins involved in post-translational modification such as protein phosphorylation, glycosylation, methylation, acetylation will be designed and synthesized. We plan to design the ligand molecules based on the structure of physiological ligands and substrates of target molecules, the information on the ligand molecules found by Molecular Ligand Discovery Research Team and the structural information on target molecules found by Molecular Ligand Target Research Team. This Team also expects to contribute to identification of target molecules by optimizing ligand molecules and developing the probe molecules. In addition, we do innovate in the novel synthetic methodologies for synthesizing ligand molecules.

Research Subject

  1. Development of molecular ligands controlling protein modification
