Hydroxocobalamin monohydrochloride (Vitamin B12a monohydrochloride) is an injectable naturally occurring form of vitamin B12 with a favorable adverse effect profile, used as a dietary supplement in the treatment of vitamin B12 deficiency including pernicious anemia[1][2].
The cobalt atom of hydroxocobalamin binds cyanide and nitric oxide and hydroxocobalamin attenuates vascular responses to NO in vitro[3].
Treatment with hydroxocobalamin before or after giving LPS attenuates LPS-induced hypotension and increases in plasma RNI and enhances LPS-induced urinary excretion of RNI. Hydroxocobalamin (20 mg/kg i.p.) given to Swiss-Webster mice 30 min before giving LPS (16 mg/kg i.p.) decreases the 24-hr mortality of LPS from 80 to 50% and the 36- and 96-hr mortality from 100 to 60% (hydroxocobalamin)[3]. More than 60% of the mice administered 35 mg/kg (0.63 mmol/kg) of NaSH (LD90) survive (at 24 h) when hydroxocobalamin (0.25 mmol/kg) is given after NaSH administration whereas less than 15% of the mice survive without hydroxocobalamin. Hydroxocobalamin (50-100 μM) or cobalt (50-100 μM) also preventes hepatocyte cytotoxicity induced by NaSH (500 μM). Furthermore, adding hydroxocobalamin 60 min later than NaSH still shows some protective activity[4].

Animal experiment: | Rats: Rats are pretreated with sterile PBS (0.1 mL/kg i.v.) 30 min before administration of LPS (0.8 mg/kg i.v.). Fifteen minutes after administration of LPS, when the 125-mediated decrease in blood pressure is maximum, the rats are administered either PBS (0.1 mI/kg i.v.) or hydroxocobalamin (20-30 mg/kg i.v.). Blood pressure, heart rate and RNI are measured[1]. Mice: Adult male CD1 mice, 25-30 g body weight are allowed to acclimatize for at least 7 days prior to experiment on standard chip bedding. All animals are fed ad libitum and are not fasted before experiments. Mice are treated with 0.1 mL/25 g volume per weight ratio of single injection. The survival of animals is recorded 24 h after the treatment[4]. |
