We are working at the interface of chemistry and biology, exploring small molecules that can bind to nucleic acids (DNAs and RNAs) and modulate their functions. Most of the human genome is transcribed into RNAs, however, only a small portion of them is translated to proteins. These non-protein-coding RNAs (non-coding RNAs, ncRNAs) are thought to have diverse roles in cellular processes, so they are emerging targets for drug development. In response to the increasing interest in the ncRNA-related topics, small molecules targeting ncRNAs have attracted considerable attention from researchers in various research fields, including chemistry, chemical biology, biotechnology, and medicine, because of their potential application in modulating the function of ncRNAs. Our main research fucuses are:

● Exploring/development of small molecules that bind to a specific RNA and application of small molecules to modulate the RNA-related biochemical reactions in cells
● Development of a method to screen and identify RNA motifs for small-molecule binding
