example 1

[0057] The preparation of example 1 helexin

[0058] Take 1 kg of Dipsacus medicinal material, add 30 g of calcium oxide, and extract 3 times with 8 times the amount of 60% ethanol under reflux, each time for 2 hours. Combine the extracts three times, filter, and recover the ethanol from the filtrate until it has no alcohol smell, add water to 3000ml, pass through the treated macroporous resin column, and first elute with 20% ethanol containing sodium hydroxide (pH value 13) for 3 times column volume, then eluted with water to neutrality, and finally eluted with 70% ethanol for 4 times the column volume, collected the eluate, and concentrated to dryness under reduced pressure; hydrolyzed 3 times with 2N hydrochloric acid containing 40% ethanol solution Hour. Filtrate, discard the hydrolyzate, wash the filter cake with deionized water until it is neutral; then heat it to boiling with 95% ethanol, add 2% medicinal activated carbon of the volume of the liquid medicine, filter ...

Abstract

The invention relates to the technical field of medicines, in particular to application of a hederagenin derivative in preparation of a hypoxia-reoxygenation injury medicine for myocardial ischemia and reperfusion injury prevention. The compound is stable in a solution; the compound has obvious protective activity against myocardial hypoxia-reoxygenation injury, especially the hypoxia-reoxygenation injury of myocardial ischemia and reperfusion injuries; the myocardium can be well protected from hypoxia-reoxygenation injury when the concentration is 80 micromole/L, and the derivative has stronger pharmacological activity than the parent nucleus hederagenin under the same dosage, so that a new choice is provided for protection against myocardial hypoxia-reoxygenation injury and myocardial ischemia-reperfusion injury.

Description

technical field [0001] The invention relates to the technical field of drug synthesis, in particular to the application of a hedera saponin derivative in the preparation of anti-myocardial hypoxia-reoxygenation injury drugs. Background technique [0002] Cardiovascular disease is a family of diseases that involve the circulatory system. Coronary heart disease, heart failure, and acute myocardial infarction are common cardiovascular diseases, and their pathogenic mechanisms are all related to myocardial cell damage caused by myocardial ischemia-reperfusion. Studies have pointed out that the pathogenesis of cardiovascular diseases is complex, and the drugs that have been marketed for treating cardiovascular diseases have the disadvantages of weak activity, low selectivity, and large side effects, which make them have certain limitations and cannot fundamentally control the disease. Drugs for the treatment of myocardial ischemia-reperfusion injury are well known in existing st...
