1,3-Bis[1-methylpyrrolidin-2-yl]propan-2-one - Uses and synthesis methods
nature
After reduction and acinization, a semi-synthetic new drug-red acinyl alcohol vinegar is obtained. This drug has good central sedation and peripheral anticholinergic effects. It is mainly used for antispasmodic and pain relief. It has therapeutic effects on diseases such as gastric ulcer and insomnia, with low toxicity and small side effects.
application
Rhizopine is an anticholinergic drug with central sedative effect and peripheral anticholinergic effect. There is also the effect of relieving asthma, dilating peripheral blood vessels and lowering blood pressure. It is characterized by strong inhibition of digestive tract peristalsis and gastric acid secretion. It has central sedative effect and peripheral anticholinergic effect. Its activity is weaker than atropine, but it has relatively strong effect on inhibiting gastrointestinal peristalsis and gastric juice secretion. There are also the effects of dilating peripheral blood vessels, increasing coronary flow and certain antiasthmatic effects. It is used for spastic pain caused by gastric ulcer and various gastrointestinal diseases.
Preparation
when using 1-methyl -2-tetrahydropyrrolidone as raw material to synthesize red ancient bean base, due to the control of reaction conditions in the synthesis process and other reasons, there are still a small amount of unreacted raw materials, which affect the product quality. In order to make it separate, the appropriate thin layer chromatography conditions were found through many experiments, and the separation of chromatographic spots was satisfactory. The atropine workshop extracts the remaining mother liquor of the alkaloids, and separates the hydrobromide of the red ancient bean alkali. The aqueous solution of the latter is ammoniated, chloroform extracted, dried, chloroform removed, and distilled under reduced pressure to obtain red ancient bean alkali: boiling point, 178-179.
