Abstract

The present invention relates to a small molecular weight alkaloid compound I whose molecular formula is C9H17NO and molecular weight is 155 and its application in preparation of medicine for stopping pain. The tests show that said compound has good paint-stopping effect, and has no effective component producing dependence.

Description

Technical field: [0001] The present invention relates to the use of alkaloid compounds, in particular to the use in the field of medicine. Background technique: [0002] Many analgesic drugs have been developed. Drugs with better analgesic effects include morphine and pethidine. This is the most effective analgesic drug currently in clinical use. However, the biggest disadvantage of this drug is that it cannot be used for a long time, otherwise, dependence or addiction will occur. Therefore, when people use this type of medicine, they need to be very cautious to avoid the above-mentioned side effects. Invention content: [0003] The present invention refers to providing an alkaloid compound capable of solving the above-mentioned technical problems. [0004] Compound I provided by the present invention has the following structural formula [0005] [0006] Molecular formula is C 9 h 17 NO, with a molecular weight of 155, is a white needle crystal. The compound ca...
