Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/?term=27799218

Vesatolimod, also known as GS-9620, is being developed in clinical studies for the 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. It is demonstrate interferon-stimulated gene induction without detectable serum interferon at low oral doses. GS-9620 is a potent and oral agonist of Toll-like receptor-7, a pattern-recognition receptor whose activation results in innate and adaptive immune stimulation

In Vitro Use Guide

The antiviral activity of GS-9620 was assessed in isolated macrophages, CD4+T cells and in total peripheral blood mononuclear cells (PBMCs) following infections with a replication component HIV-1BaL. In uninfected cultures, the viability of each cell type remained unchanged up to 10 μM GS-9620, the maximum concentration tested. GS-9620 was inactive against HIV in isolated CD4+ T cells and macrophages up to the highest concentration tested (10 µM), but did show dose-dependent inhibition of HIV-1 replication in complete PBMCs following infection with either HIV-1BaL (EC50 = 536 nM) or HIV-1VSVg (EC50 = 953 nM). Although GS-9620-mediated antiretroviral activity varied significantly between individual donors, its antiretroviral potency in PBMCs was enhanced by approximately 35-fold when GS-9620 was added 48 hours prior to infection with HIV-1VSVg (EC50 = 27 nM).
