|Description||Telbivudine is a potent, and selective HBV reverse transcriptase inhibitor, used to treat HBV infection.|
Telbivudine shows potent, selective, and specific antiviral activity against HBV and other hepadna viruses. Telbivudine is phosphorylated by intracellular thymidine kinases to the active triphosphate form, which has an intracellular half-life of 14 hours. Telbivudine 5′-triphosphate inhibits HBV DNA polymerase (reverse transcriptase) by competing with the natural substrate, dTTP.  Telbivudine significantly increases the production of tumour necrosis factor-alpha and interleukin-12 in MHV-3-induced macrophages. Telbivudine significantly elevates serum levels of interferon-gamma. Telbivudine treatment enhances the ability of T cells to undergo proliferation and secrete cytokines but does not affect cytotoxicity of infected hepatocytes. Telbivudine treatment suppresses programmed death ligand 1 expression on T cells.  Telbivudine remains active as shown by respective fold-changes of 0.5 (N236T) and 1.0 (A181V and A194T). Telbivudine 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.

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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
