Product Description

Pritelivir mesylate (formerly known as AIC-316, BAY-571293), the mesylate salt of Pritelivir, is a novel and potent helicase primase inhibitor with antiviral effects against herpes simplex virus (HSV). It inhibits HSV with IC50 of 20 nM for both HSV-1 and HSV-2. It represents a new class of potent inhibitors of HSV that target the virus helicase primase complex. BAY 57-1293 exhibits anti-herpes activity through inhibiting the helicase-primase and affecting the viral DNA synthesis. In the in vitro viral replication assay, BAY 57-1293 shows inhibition against HSV-1 F, HSV-2 G and acyclovir-resistant HSV-1 F mutant with IC50 value of 20nM. Thus, BAY 57-1293 has significant potential for the treatment of HSV disease in humans, including those resistant to current medications.

Targets
HSV-1(IC50=0.02 μM);HSV-2(IC50=0.02 μM)
ln Vitro
Pritelivir (formerly known as AIC316, BAY 57-1293) is a novel and potent helicase primase inhibitor that showed antiviral effect on herpes simplex virus (HSV) with IC50 of 20 nM for both HSV-1 and HSV-2. It represents a new class of potent inhibitors of HSV that target the virus helicase primase complex. BAY 57-1293 exhibits anti-herpes activity through inhibiting the helicase-primase and affecting the viral DNA synthesis. In the in vitro viral replication assay, BAY 57-1293 shows inhibition against HSV-1 F, HSV-2 G and acyclovir-resistant HSV-1 F mutant with IC50 value of 20nM. Thus, BAY 57-1293 has significant potential for the treatment of HSV disease in humans, including those resistant to current medications. The mechanism of action is that BAY 57-1293 directly inhibits the ATPase activity of the viral helicase-primase enzyme complex in a dose-dependent manner. BAY 57-1293 also shows potent antiviral activity against acyclovir resistant HSV mutants. BAY 57-1293 reduces Aβ and P-tau induced by herpes simplex virus type 1 in vero cells.
ln Vivo
BAY 57-1293 (p.o.) shows profound antiviral activity in murine and rat lethal challenge models of disseminated herpes (0.5 mg/kg), in a murine zosteriform spread model of cutaneous disease (15 mg/kg), and in a murine ocular herpes model.

Cell Assay
In the in vitro viral replication assay, BAY 57-1293 shows inhibition against HSV-1 F, HSV-2 G and acyclovir-resistant HSV-1 F mutant with IC50 value of 20nM.

For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

*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)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
