The indicated liver cancer cell lines—Hep-3B, Huh-7 and PLC were treated with or without 5 types anti-hepatitis B virus drugs (C) with the concentration of 100 μM, and M1 virus (MOI = 10) for 72 hours. Following 72 hours, cell viabilities were determined by MTT assay (mean ± SD). N.S. Not significant.

Lamivudine’s anti- HBV activity, like its anti-HIV activity, has been shown to depend on the ability of LMV-TP to serve as both substrate and inhibitor of the DNA- and RNA-dependent polymerase activities of the HBV P gene product. Lamivudine owes its activity to the remarkably broad substrate specificity of deoxycytidine kinase and the unusual substrate preference of the HBV polymerases for dNTPs with the unnatural L-conformation, whereas the anti-HBV activity of PCV appears to depend on several factors including optimal phosphorylation (sufficient for antiviral activity but not cytotoxicity) by key cellular enzymes, the long intracellular half-life of PCV-TP and the ability of PCV-TP to inhibit the HBV RT priming reaction as well as RT and DNA polymerase activity. [1] Lamivudine and Penciclovir inhibits duck hepatitis B virus (DHBV) replication to a comparable extent when used alone, and in combination, the two nucleoside analogs acts synergistically over a wide range of clinically relevant concentrations. Lamivudine combined with Penciclovir is more effective in reducing the normally recalcitrant viral covalently closed circular (CCC) DNA form of DHBV than either drug alone. [2] Lamivudine inhibits p24 antigen production by HIV-I in PBMC, with ED50s ranging from 0.07 μM to 0.2 μM. [3] |

Bio Calculators
Molarity Calculator
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).
Dilution Calculator
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.
