The invention discloses application of 9 ''-
salvianolic acid B monomethyl ester in preparation of a
medicine for treating
ischemic heart disease, and belongs to the technical field of biological
medicine. The CAS number of the 9 ''-
salvianolic acid B monomethyl ester is 1167424-31-8, the
ischemic heart disease refers to myocardial injury induced by heart
ischemia reperfusion, and the invention further provides a pharmaceutical composition or a
small molecule injection preparation. Animal experiments show that 9 ''-
salvianolic acid B monomethyl ester is exogenously injected to relieve myocardial injury of a mouse and improve the heart function of the mouse, and it is proved that the
medicine containing 9''-
salvianolic acid B monomethyl ester can improve the
ischemic heart disease, especially myocardial injury caused by heart
ischemia reperfusion, and has a good application prospect. The invention provides potential
drug selection and research direction for preventing and treating ischemic
heart disease, and has important clinical application value.
