Synthesis method

Meta-dimethylaminophenol (see 15070) and dimethylcarbamoyl chloride via ester The neostigmine base is obtained by chemical reaction, and then the quaternary ammonium salt is reacted with methyl bromide to obtain neostigmine bromide. For example, by reacting the neostigmine base with dimethyl sulfate to form a quaternary ammonium salt, neostigmine methyl sulfate ([51-60-5]).

Purpose

This product has a reversible cholinesterase inhibitory effect, causing acetylcholine to not be enzymatically decomposed and existing in cholinergic nerve endings for a long time, which can cause Exciting smoothing machine and skeletal muscle; strong effect on skeletal muscles, small miotic force; mostly used for myasthenia gravis, postoperative abdominal distension and urinary retention, and can also be used for supraventricular paroxysmal tachycardia, and Detoxification of tubocurarine overdose. Neostigmine methyl sulfate is for injection.
