Bay 41-4109 S-isomer is the less active enantiomer of Bay 41-4109. It shows less activity than Bay 41-4109. BAY 41-4109 is a novel and potent inhibitor of human hepatitis B virus (HBV) with an IC50 of 53 nM. BAY-41-4109 is a heteroaryldihydropyrimidine (HAP) antiviral compound effective on Hepatitis B virus (HBV) capsid assembly and on preformed HBV capsids.
ln Vitro |
Mice: For this study, HBV-transgenic mice are employed. The compounds (BAY 41-4109) are given to mice twice a day for 28 days in a suspension solution formulated with 0.5% tylose. The placebo is the 0.5% tylose. The animals are killed six hours after the last treatment, and the livers are taken out and frozen right away for further examination. The anesthetized animals' hearts are punctured to obtain blood[1].

ln Vivo |
Viral DNA in liver and plasma is dose-dependently reduced by BAY 41-4109, with an efficacy that is similar to that of 3TC. HBV transgenic mice's livers had lower levels of the hepatitis B virus core antigen (HBcAg) when BAY 41 -4109 is added. According to pharmacokinetic studies conducted on mice, rats and dogs exhibit fast absorption, with dose-proportional plasma concentrations of about 60% and a bioavailability of 30% [1]. By focusing on the viral capsid, BAY41-4109 prevents the growth of viruses in vivo [2].

Animal Protocol |
Rodents: HBV-transgenic mice are used in this study. For a duration of 28 days, mice are administered the compounds (BAY 41-4109) twice daily in a suspension solution containing 0.5% tylose. 0.5% tylose serves as the placebo. After the animals are killed six hours after the last treatment, the livers are immediately removed and frozen for additional analysis. To get blood, punctures are made in the hearts of the unconscious animals[1].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations

*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.
