Abstract

The invention discloses a conjugate of paeonol and ozagrel, a pharmaceutical composition and medical application of the conjugate. The conjugate of paeonol and ozagrel has a structural formula shown in the specification. The invention also discloses application of the conjugate of paeonol and ozagrel in preparation of a medicine for preventing or treating cardiovascular and cerebrovascular diseases caused by platelet aggregation, and also discloses the pharmaceutical composition of the conjugate of paeonol and ozagrel, and a carrier containing the conjugate of paeonol and ozagrel or a pharmaceutically acceptable vector. The compound has the effect of preventing or treating cardiovascular and cerebrovascular diseases caused by platelet aggregation, and especially treating the thrombotic cardiovascular and cerebrovascular ischemia or infarct and other diseases.

Description

technical field [0001] The invention relates to the field of medicinal chemistry, in particular to a paeonol-ozagrel conjugate and a pharmaceutical composition containing them. Background technique [0002] Cardiovascular and cerebrovascular diseases are common and frequently-occurring diseases that seriously endanger human health. With the aging of the social population, the incidence rate is increasing day by day. [0003] Thromboembolism is one of the important factors leading to cardiovascular and cerebrovascular diseases. Coronary artery disease and its corresponding ischemic complications can cause a variety of clinical syndromes, such as stroke, myocardial infarction or peripheral arterial disease. The main cause is the formation of A blood clot blocks a blood vessel, causing severe ischemia. Thromboembolic diseases with coronary thrombosis and cerebral thrombosis as the core also have high morbidity and mortality in my country. Therefore, preventing thrombosis has b...
