Product Description

Tomeglovir (also known as BAY-38-4766) is a novel, potent and non-nucleoside anti-CMV (cytomegalovirus) agent which inhibits processing of viral DNA-concatemers with IC50s of 0.34 μM and 0.039 μM for HCMV and MCMV. Tomeglovir protects against cytomegalovirus (CMV) disease and mortality in immunocompromised guinea pigs. Tomeglovir-resistant HCMV and MCMV strains are not cross-resistant to the nucleoside analogues ganciclovir and cidofovir or the pyrophosphate analogue foscarnet, indicating a different mode of action. Tomeglovir is highly specific for the viral as opposed to cellular functions, since UL89 is related to a bacteriophage terminase and no human equivalent exists.

Biological Activity I Assay Protocols (From Reference)
Targets
HCMV(IC50= 0.34 μM);HCMV(MCMV=0.039 μM)
ln Vitro
Strong anti-CMV agent tomeglovir (BAY 38-4766) has IC50 values for HCMV and MCMV of 0.34 μM and 0.039 μM, respectively. Additionally, HELF and NIH 3T3 cells are suppressed by tomeglovir, with CC50s of 85 μM and 62.5 μM, respectively[1]. At EC50s of 1.03 ± 0.57 μM and less than 1 μM, tomeglovir (BAY 38-4766) inhibits the HCMV Davis and different strains of monkey CMV[2].
ln Vivo
Tomeglovir (BAY 38-4766; 3, 10, 30, 100 mg/kg, p.o.) decreases MCMV-DNA in the salivary glands, livers, and kidneys of NOD-SCID mice infected with MCMV in a dose-dependent manner while also extending the mice's survival. In the hollow fiber mouse model, tomeglovir (10, 25 and 50 mg/kg) exhibits antiviral activity[1]. In SCID mice infected with MCMV, tomeglovir (BAY 38-4766) exhibits antiviral activity; in rats and mice, the LD50 is greater than 2000 mg/kg[2].
Cell Assay
A total of 100 μL of EMEM/10 is added to each well of 96-well microtitre plates to assess the toxicity of the drugs. Following the addition of 2 μL of 50 mM Tomeglovir stock solutions in duplicate into 198 μL in row 2, 100 μL up to row 12 and 100 μL of a HELF, NHDF, or 3T3 cell suspension (5 × 103 cells/mL) are added per well in a series of two-fold dilutions.Row 1 is the control cell that has not been treated. Following a 6-day incubation period at 37°C and 5% CO2, the cells are rinsed once with phosphate-buffered saline (PBS) and 200 μL of fluorescein diacetate, a fluorescent dye solution containing 10 μg/mL in PBS at pH 7.2, are added to each well. A Fluorskan Ascent fluorimeter (emission filter: 530 ± 15 nm, excitation filter: 485 ± 11 nm) is used to measure the fluorescence signal after 45 minutes. CC50 values are calculated graphically, and the relative fluorescence units (RFUs) of treated cells are expressed as percentages of untreated cell controls[2].
Animal Protocol
Mice [1]
Avertin 2.5% (0.015-0.017 mL/g body weight) is used to anesthetize NOD/LtSz-scid/j mice weighing 20–30 g. Avertin 100% is made up of 10 g tribromoethyl alcohol in 10 mL tertiary amyl alcohol. The abdomens are opened and the fibers are inserted intra-abdominally after the belly has been shaved and cleaned aseptically. Two layers of sutures are used to close the abdomens. In this study, only asymptomatic animals are involved. The mice receive Tomeglovir treatment at the recommended dosages twice a day for four days in a row starting the day after transplantation. Under these circumstances, day 5 viral peak titers are seen in preliminary experiments[1].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
