Loxoribine | TLR7 agonist

Loxoribine (21288-39-9) is a toll-like receptor 7 (TLR7) agonist.1 A potent immunostimulant with a relatively broad spectrum of immunobiological activities including upregulation of the activity of B cells, T cells, NK cells, macrophages and LAK cells.2 Induces secretion of IFN-γ by NK cells.3 Inhibits influenza A infection in chickens.4 Induces tumor regression by reversing Treg-induced immunosuppression.5
