The invention relates to the technical field of medicines, discovers that a
natural product glabroolide can be used as an M3 (M3)
receptor stimulant and application thereof, and particularly relates to discovery of a glabroolide action target spot, the target spot is an M3
receptor, the M3
receptor stimulant is glabroolide or a derivative thereof, and the application of the glabroolide in the M3 receptor
stimulant is shown in the description. And one or more than two of the corresponding pharmaceutically acceptable salts of the compound are active ingredients, and in-vitro
cell experiments show that the compound is an M3 receptor
agonist. At present, researches show that the M3 receptor is related to heart diseases, respiratory diseases,
sicca syndrome,
peptic ulcer disease,
frequent urination, prune syndrome, chronic obstructive
pulmonary disease,
cirrhosis,
irritable bowel syndrome and other diseases, while the M3 receptor stimulant has a protective effect on
myocardial cell injury. The compound has a certain
treatment effect on diseases such as arrhythmia, respiratory depression and
sicca syndrome, so that a novel M3 receptor
agonist Miao compound with a clear action target can be provided for the related diseases.
