Used in research for its antiviral properties, particularly against hepatitis B virus (HBV). It acts as a core protein allosteric modulator (CpAM), disrupting the normal assembly of the viral capsid, which is essential for viral replication. This makes it a candidate for development in functional cure strategies for chronic hepatitis B. Studies show it can reduce levels of viral DNA and antigens in cell cultures and animal models. Often used in combination with other antivirals to assess synergistic effects. Not approved for clinical use but valuable in preclinical drug development.
