Biological Activity

Description Telbivudine is a potent, and selective HBV reverse transcriptase inhibitor, used to treat HBV infection.
HBV RT [1]
In vitro

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. [1] 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. [2] 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.

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

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.
