The Uses of distigmine bromide

Distigmine Bromide is a cholinesterase inhibitor.

Definition

ChEBI: Distigmine bromide is an organic bromide salt of distigmine. It is an anticholinesterase drug used for the treatment of myasthenia gravis and postoperative urinary retention. It has a role as an EC 3.1.1.8 (cholinesterase) inhibitor. It is a pyridinium salt and an organic bromide salt. It contains a distigmine.

Manufacturing Process

2 parts of sodium are dissolved in 24 parts of methanol and to the solution of sodium methylate formed 8.25 parts of 3-oxypyridine and 90 parts of xylene (mixture of isomers) are added. Then the mixture is distilled in an atmosphere of nitrogen as protecting gas until the boiling point of xylene is reached and the methanol is completely removed. The remainder is brought together with a solution of 11.7 parts of hexamethylene-bis-(N-methyl carbamic acid chloride) in 45 parts of xylene and maintained 4 hours at a temperature of80°C under vigorous stirring.
After having been cooled it is washed three times in water, three times in a 5% solution of caustic soda, and then another three times in water. The solution in xylene is dried over sodium sulfate and the xylene is completely distilled off in vacuo. Thus 11.0 parts of hexamethylene-bis-(Nmethylcarbamic acid-3-pyridyl ester) are obtained.
7.3 parts of hexamethylene-bis-(N-methyl carbamic acid-3-pyridyl ester) are dissolved in 120 parts of acetone, then 22 parts of methyl bromide are added and the mixture is left to stand at room temperature until the reaction is finished, whereby crystals are precipitated. The reaction product after being drawn off and dried (9.9 parts) can be purified by dissolving in acetic acid and precipitating with methyl ethyl ketone. The hexamethylene-bis-(N-methyl carbamic acid-3-pyridyl ester bromomethylate) has a micro melting point between 147°C and 150°C.
