Embodiment 1

[0021] Embodiment 1, the preparation of the pharmaceutical composition of anti-platelet aggregation

[0022] According to the molar concentration ratio of each component shown in Table 1, cinnamic acid, p-coumaric acid and coumarin were weighed and mixed to obtain a pharmaceutical composition.

[0023] Table 1 Molar concentration ratio of each component

[0024]

Embodiment 2

[0025] Embodiment 2, the experiment of the inhibitory effect of pharmaceutical composition on ADP-induced platelet aggregation

[0026] 1. Preparation of anticoagulation buffer Buffer A

[0027] Sodium chloride 130mmol / L, sodium citrate 10mmol / L, sodium bicarbonate 9mmol / L, glucose 6mmol / L, magnesium chloride 0.9mmol / L, potassium dihydrogen phosphate 0.81mmol / L, trishydroxymethylaminomethane 10mmol / L L mixed to prepare anticoagulation buffer solution Buffer A.

[0028] 2. Preparation of the pharmaceutical composition solution

[0029] a. Add Buffer A to the pharmaceutical composition of test number 1 to form a pharmaceutical composition solution 1 with a coumarin molar concentration of 720 μM;

[0030] b. Add Buffer A to the pharmaceutical composition of test number 2 to form a pharmaceutical composition solution 2 with a coumarin molar concentration of 640 μM;

[0031] c. Add Buffer A to the pharmaceutical composition of test number 3 to form a pharmaceutical composition s...

Abstract

The invention provides an anti-platelet aggregation pharmaceutical composition comprising cinnamic acid, p-coumaric acid and coumarin, wherein the molar concentration ratio of the cinnamic acid to the p-coumaric acid to the coumarin is (1-9):(1-9):(4-36). The experiment result shows that the inhibiting effect on ADP-induced platelet aggregation caused by combined utilization of the cinnamic acid, the p-coumaric acid and the coumarin is obviously higher than that caused by independent use of the coumarin.

Description

technical field [0001] The invention belongs to the field of medicines, in particular to a pharmaceutical composition for anti-platelet aggregation. Background technique [0002] Under physiological conditions, platelets in the undamaged vascular system do not undergo activation and aggregation, and have the function of protecting endothelial cells and preventing the formation of cardiovascular diseases such as atherosclerosis. Platelet aggregation plays a key role in the normal coagulation mechanism, but when it deforms abnormally, adheres, and aggregates, it can form a thrombus. For example, when platelets are stimulated by agonists such as thrombin (THR), they are activated, aggregate, form thrombus, and lead to cardiovascular events. During cerebral ischemia-reperfusion, oxygen free radicals and other signaling molecules can activate inflammatory cytokines, cause the release of chemokines, and upregulate adhesion molecules, which in turn lead to enhanced platelet adhesi...
