Identification of novel small molecular ligands is essential to understand diverse biological phenomena and to control the biological systems by chemical methods. This project focuses on the development of useful molecular ligands that are expected to contribute to an advance in environmental and resource sciences by employing chemical libraries that consist of microbial metabolites and/or synthetic compounds. In particular, we search into novel active compounds by constructing a variety of phenotypic screening systems using genetically modified animal, plant and yeast cells, and in vitro screening systems using various target proteins that include enzymes for metabolism and epigenetics. In addition, we construct new platforms for developing high throughput screening systems. Our goal is to identify and provide unique molecular ligands that are useful for chemical biology research aiming at exploiting new area of environmental and resource sciences.
