Product Description

Benserazide HCl (Ro-44602; Serazide; Ro 4-4602), the hydrochloride salt of Benserazide, is a carbohydrazide-based, peripherally acting inhibitor of aromatic L-amino acid decarboxylase/AADC or DOPA decarboxylase and a medication used in combination with levodopa (madopar) to treat Parkinson's disease, parkinsonism, and restless leg syndrome.

Biological Activity I Assay Protocols (From Reference)
ln Vitro
Treatment with benserazide hydrochloride (BH) and levodopa (LD) alone or in combination (benserazide hydrochloride + LD) (25 μM; 0 hours, 12 hours, 24 hours, and 168 hours; SH-SY5Y) decreases protein aggregation and can limit protein aggregation. Amyloid-induced cytotoxicity in human neuroblastoma cell lines. Both benserazide hydrochloride and LD can be efficient inhibitors of the formation of cytotoxic HSA aggregates, and the inhibitory effect is more visible when the two medicines are introduced at the same time [2].
ln Vivo
Benserazide (5–50 mg/kg; intraperitoneal injection; male Wistar rats) treatment raised exogenous L-DOPA-derived extracellular DA levels and considerably extended the time to peak DA levels in 6-OHDA-injured rats. ..Depend on. With 10 mg/kg and 50 mg/kg benserazide, there was a substantial decrease in AADC activity in denervated striatal tissue. Benserazide alters the metabolism of exogenous L-DOPA by lowering central AADC activity in the striatum of rats suffering from nigrostriatal denervation [1].
Cell Assay
Cell Viability Assay[2]
Cell Types: SH-SY5Y Cell
Tested Concentrations: 25 μM
Incubation Duration: 0 hrs (hours), 12 hrs (hours), 24 hrs (hours) and 168 hrs (hours)
Experimental Results: Enhanced cell viability and inhibited cytotoxic human serum albumin (HSA) aggregates Formation.
Animal Protocol
Animal/Disease Models: Male Wistar rat 6-hydroxydopamine (6-OHDA) (8 Ag/4 Al)[1]
Doses: 5 mg/kg, 10 mg/kg or 50 mg/kg (pharmacokinetic/PK/PK study) Give Medication: intraperitoneal (ip) injection.
Experimental Results: Extracellular DA levels derived from exogenous L-DOPA increased, and the time to reach peak DA levels was Dramatically prolonged in a dose-dependent manner. AADC activity in denervated striatal tissue was Dramatically diminished at 10 mg/kg and 50 mg/kg.

Solubility Data
Solubility (In Vitro)
DMSO : ~100 mg/mL (~340.48 mM)
H2O : ≥ 50 mg/mL (~170.24 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.08 mg/mL (7.08 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
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.

Solubility in Formulation 2: ≥ 2.08 mg/mL (7.08 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
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 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline 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
