Product Description
Pyridoxylamine diHCl is an inhibitor (blocker/antagonist) of glycation end products (AGE) and lipidation end products (ALE) and can prevent retinal vasculopathy caused by diabetes.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
The B6 vitamin pyridoxamine (PM) is a strong reactive carbonyl scavenger that prevents the production of AGE by blocking the last stages of the glycation reaction [1].
ln Vivo
In STZ diabetic rats, pyridoxamine prevents the production of CML and CEL, restricts the cross-linking of skin collagen, and eventually prevents the onset of nephropathy. Because it offers little defense against lipid peroxidation, pyridoxamine does not seem to have an antioxidant role. In Zucker rats, it also inhibits the production of 4-hydroxynonenal adducts and malondialdehyde on proteins, hence preventing protein modifications of lipid peroxidation products [1].

Additional Infomation
Pyridoxamine dihydrochloride is a hydrochloride obtained by combining pyridoxamine with two molar equivalents of hydrochloric acid. Used for treatment of diabetic nephropathy. It has a role as an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite, a human metabolite, a mouse metabolite, a plant metabolite, an iron chelator and a nephroprotective agent. It is a hydrochloride and a vitamin B6. It contains a pyridoxamine(2+).

Solubility Data
Solubility (In Vitro)
DMSO : ~120 mg/mL (~497.70 mM)
H2O : ~120 mg/mL (~497.70 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 3 mg/mL (12.44 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 30.0 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: ≥ 3 mg/mL (12.44 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 30.0 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.

Solubility in Formulation 3: ≥ 3 mg/mL (12.44 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 30.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.


Solubility in Formulation 4: 100 mg/mL (414.75 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication.

*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
