3'-O-(2-Methoxyethyl)guanosine

3'-O-(2-Methoxyethyl)guanosine is a guanosine analogue. Some guanosine analogs have immunostimulatory activity. In some animal models, they also induce type I interferons, producing antiviral effects. Studies have shown that the functional activity of guanosine analogs is dependent on the activation of Toll-like receptor 7 (TLR7).

3'-O-(2-Methoxyethyl)guanosine is a remarkable modified nucleoside with immense potential in the field of antiviral drug discovery. This exquisite compound takes center stage in targeting viral RNA-dependent RNA polymerases, thus rendering it a powerful weapon in research of respiratory syncytial virus (RSV) and hepatitis C virus (HCV).
