Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	HBV RT
In vitro	Telbivudine shows potent, selective, and specific antiviral activity against HBV and other hepadna viruses. This compound is phosphorylated by intracellular thymidine kinases to the active triphosphate form, which has an intracellular half-life of 14 hours. Its 5′-triphosphate inhibits HBV DNA polymerase (reverse transcriptase) by competing with the natural substrate, dTTP. This chemical significantly increases the production of tumour necrosis factor-alpha and interleukin-12 in MHV-3-induced macrophages. It significantly elevates serum levels of interferon-gamma. This treatment enhances the ability of T cells to undergo proliferation and secrete cytokines but does not affect cytotoxicity of infected hepatocytes. It suppresses programmed death ligand 1 expression on T cells. The compound remains active as shown by respective fold-changes of 0.5 (N236T) and 1.0 (A181V and A194T). It is not active against HBV strains bearing lamivudine mutations L180M/M204V/I but remains active against the M204V single mutant in vitro, potentially explaining the difference in resistance profiles between telbivudine and lamivudine.
