CAS#: 1228585-88-3

Description: Vesatolimod, also known as GS-9620, is a potent and oral agonist of Toll-like receptor-7 developed for finite treatment of chronic hepatitis B viral (HBV) infection, with the goal of inducing a liver-targeted antiviral effect without inducing the adverse effects associated with current systemic interferon-α (IFN-α) therapies. GS-9620 demonstrate interferon-stimulated gene induction without detectable serum interferon at low oral doses. GS-9620 can induce a sustained antiviral response in the woodchuck model of CHB.
