Tenofovir blocks reverse transcriptase and hepatitis B virus infections.
1 Customer Review
The Nucleotide analog reverse-transcriptase inhibitor Tenofovir disoproxil fumarate was added to TZM-bl cells. Cells were inoculated with 0.05 ng mock-exposed and semen-exposed HIV, and 0.5 ng HIV as infectivity-matched control. Infection rates were measured 3 days post infection by measuring β-galactosidase or or 4 days post infection by measuring luciferase activities. The left panels show the mean enzyme activities ± standard deviation derived from triplicate infections. RLU/s: relative light units per second. Middle panels show normalized infection rates in which reporter enzyme activities obtained from infected cells in the absence of inhibitor were set at 100%. The right panels depict the calculated IC50 values. The number above the bar represents the fold-change in the IC50 derived from 0.05 ng semen-exposed relative to 0.05 or 0.5 ng mock-exposed virus infection. Ns, no statistically significant difference; **** p<0.0001; *** p<0.001 (unpaired t-test).

|Description||Tenofovir blocks reverse transcriptase and hepatitis B virus infections.|
|Features||Tenofovir disoproxil fumarate is the prodrug form of tenofovir.|
Tenofovir reduces the viral cytopathic effect of HIV-1(IIIB), HIV-2(ROD) and HIV(EHO) with EC50 of 1.15 μg/mL, 1.12 μg/mL and 1.05 μg/mL in MT-4 cells. Tenofovir also reduces the viral cytopathic effect of SIV(mac251) , SIV(B670) ,SHIV(89.6) and SHIV(RTSHIV).  Tenofovir is uniquely active against multinucleoside-resistant HIV expressing the Q151M mutation, but shows reduced susceptibility to the T69S insertion mutations.  Tenofovir inhibits hepatitis B virus (HBV) activity in HepG2 2.2.15, HepAD38 and HepAD79 cells.  Tenofovir (4 μM) completely inhibits the growth of HIVIIIB in MT-2 cells. Tenofovir inhibits synthesis of negative strand strong-stop DNA with IC50 of 9 µM for wild-type RT, 6 µM for M184V RT and 50 µM for K65R RT. 
|In vivo||Tenofovir (30 mg/kg) completely prevents SIV infection in all macaques without toxicity. Tenofovir treatment reduces plasma viral RNA levels to undetectable, with parallel decreases in the infectivity of plasma and infectious cells in peripheral blood mononuclear cells and cerebrospinal fluid (CSF) and stabilization of CD4+ T-cell numbers. Tenofovir (30 mg/kg, s.c.) completely abrogates HIV infection via intravaginal exposure in pig-tailed macaques. |

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × 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.
