Research Subject(s)
Novel coronavirus (SARS-CoV-2) outbreak and antimicrobial resistance are impacting global health and show importance of novel therapeutics. Our research themes are the development of novel drugs for infectious diseases. Additionally, we analyze the mechanisms of drug resistance and the intermolecular interactions between compounds and proteins.
Key Words
outbreak / drug resistance / drug development / Antiviral drug / Antibacterial drug
Research Activities

Development of novel therapeutics for human immunodeficiency virus infection
Using X-ray crystal structural analyses, we identified important interactions, which  play key roles in highly potent activity of the novel compounds against both wild-type and drug-resistant HIV-1 strains and their substantially high genetic barrier.

Development of novel antibacterial compounds
We identified novel antibacterial drugs and analyzed their antibacterial mechanisms.
