Definitions
- Methylcobalamin is a cobalamin (eCbl or MeB12) used in the treatment of peripheral neuropathy, diabetic neuropathy, and as a preliminary treatment for amyotrophic lateral sclerosis. It is a form of vitamin B12 and different from danocobalamin where the cyanide group is replaced by a methyl group. This vitamer is one of two active coenzymes used by vitamin B12-dependent enzymes and is specifically the form of vitamin B12 used by homocysteine methyltetrahydrofolate methyltransferase 5 (MTR), also known as methionine synthase.
- MTR homocysteine methyltetrahydrofolate methyltransferase 5
- Metücobaiamine is notable for being one of the few examples in the nature of an authentic organometallic bond, although N ⁇ -CH3 intermediaries are proposed for the final step of methanogenesis. It is also equivalent to vitamin B12, for example to treat pathologies that occur due to vitamin B12 deficiency, such as pernicious anemia.
- the pH is adjusted (6.5 or 7.0) with concentrated hydrochloric acid, and where no resin is needed to purify the Methylcobalamin, while in the processes where the pH is not adjusted it is necessary to use ion exchange resins for purification.
- the yields are between 80 to 90%, either by pH adjustment and recrystallization or by purification with Resins.
- JP-62056491 A called HIGH PURITY METILCOBALAMINE PRODUCTION
- the denaturation of cyanocobalamin is described, adjusted to 2.5-7.0 pH, bringing the resulting reaction mixture to a chromatographic column of silica gel and eluting with the divinylbenzene polymer and styrene one after another, the eluate is concentrated and the compound crystallized, essentially obtaining metolcobalamin.
- JP 8143590 a reaction mixture of hydroxycobalamin and cyanocobalamin is obtained by conventional cyanocobalamin methylation under oxygen-free conditions using an inert gas.
- cyanocobalamin is reduced with sodium borohydride in deionized water, with subsequent methylation reaction by adding Mohr salt, ferric chloride and methyl iodide to the system, it is recommended that the concentration of dissolved oxygen in deionized water be less than or equal at 0.1 ppm eliminating it using an inert gas.
- the inert gas is also used in the isolation process to reduce the amount of oxygen present.
- a method of manufacturing the methylcobalamin from cyanocobalamin is described, in which the instillation of a reduced cobalamin is carried out, characterized in that it comprises the steps of a solution containing at least 40 g per liter of cyanoeobalamin in a mixture of methanol and water Mestyl acid oxalate and a metal powder capable of releasing hydrogen by action on methyl acid oxalate are added to this solution, in order to simultaneously reduce cyanoeobalamin reduction and reduced cobalamin methylation in methicobalamin, while maintaining the reaction medium at a temperature between 28 and 32 ° C.
- methylcobalamin In other processes for obtaining methylcobalamin, the substitution of the cyano group by a methyl group is described, which comes from a halogenated derivative of Trimethylsulfonium or trimethylsulfoxonium (loduro, Bromide or Chloride), and some other methyl group donating agents, such as Monomethyl oxalate and dimethyl carbonate, in the presence of a chelating agent (eg, Chlorides or sulfates of iron, Nickel, Cobalt, Zinc) and a reducing agent (Sodium borohydride, due to its solubility in water).
- a chelating agent eg, Chlorides or sulfates of iron, Nickel, Cobalt, Zinc
- a reducing agent sodium borohydride, due to its solubility in water.
- aqueous media or Water-solvent mixture Water / Acetone or Water / Methanol aided by 2-Butanone
- the present work shows how to obtain methylcobalamin using dimethyl sulfate as an alkylating agent, either alone or as a Vilsmeier complex, with non-alkylated, monoalkylated and dialkylated, sodium borohydride as reducing agent, without using chelating agent.
- Metylcobalamin obtained from Example 4 is used. 5g Raw Methylcobalamin Assets are suspended in 89 ml of Demineralized Water. The pH 2.3-2.6 is adjusted with 9% HCI. Prepare the column with 100 mL of SEPABEADS ® SP207 Adsorption resin, previously activated with Methanol and washed with demineralized water. The dissolved Methylcobalamin is loaded in water, with a flow of 7 mUmin. At the end of the load, wash with demineralized water, until a negative Chloride test is obtained using silver nitrate reagent.
- Methylcobalamin was identified by HPLC method.
