T 705 (CAS 259793-96-9) is an anti-viral drug targeting RNA-dependent RNA polymerase (RdRp). T 705 exerts its biological activity primarily through selective inhibition of viral RdRp, thereby suppressing viral genome replication. In biochemical assays, T 705 demonstrates inhibitory activity, with IC50 values typically ranging from micromolar to submicromolar concentrations, depending on specific viral polymerase targets. T 705 holds research potential in antiviral studies against various RNA viruses, including influenza viruses, Ebola virus, and other emerging or re-emerging viral pathogens.
