Biological Activity

Human Endogenous Metabolite |
Hydroxocobalamin (1 mM) acetate shows no significant improvement in key mitochondrial respiratory states and no attenuation of superoxide production in Cyanide-poisoned peripheral blood mononuclear cells (PBMC) and human aortic smooth muscle cells (HASMC)[4].
Hydroxocobalamin (50-100 μM) acetate prevents hepatocyte cytotoxicity induced by NaSH in isolated rat hepatocytes[8].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Hydroxocobalamin (25-50 mg/kg; i.v.; 14 days) acetate significantly reduces Cyanide toxicity in rats ingesting Amygdalin (HY-N0190)[6].
Hydroxocobalamin (75-150 mg/kg; i.v.) acetate significantly reduces mortality from Potassium cyanide poisoning in adult beagle dogs, and is associated with cardiovascular recovery and improvement in acid-base status[7].
Hydroxocobalamin (0.25 mmol/kg; i.p.; 2 min after NaSH administration) acetate effectively prevents NaSH-induced death in mice at 24 h[8].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:Male Wistar strain albino rats (weight 150-165 g) with Cyanide poisoning induced by oral Amygdalin ingestion[6]
-
Dosage:25 mg/kg or 50 mg/kg
-
Administration:Intravenous injection, 14 days
-
Result:Reduced blood cyanide and serum lactate levels in a dose-dependent manner.
Normalized packed cell volume (PCV), haemoglobin concentration, and blood pH.
Prevented histological alterations in the liver, with no significant histological change in the colour and size of the hepatic lobes.
-
Animal Model:Adult beagle dogs (male and female, mean weight 8.9-9.2 kg) with acute cyanide poisoning induced by intravenous Potassium cyanide infusion[7]
-
Dosage:75 mg/kg or 150 mg/kg
-
Administration:Intravenous infusion
-
Result:Significantly reduced mortality rate.
Caused 15 of 19 animals to survive through 14 days at 75 mg/kg, and all 18 animals survived through 14 days at 150 mg/kg.
Led to rapid cardiovascular recovery, with increased blood pressure starting 1-3 min after infusion.
Improved acid-base status, with lower arterial lactate concentrations and higher arterial pH values.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (1.80 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (1.80 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
