Problems solved by technology

But sometimes thrombosis may have no obvious symptoms, such as the common deep vein thrombosis of the lower extremities, only calf soreness and discomfort, many patients think it is fatigue or catch a cold, do not take it seriously, so it is easy to miss the best time for treatment
It is particularly regrettable that many doctors are prone to misdiagnose this, and when typical lower extremity edema occurs, it will not only bring difficulties to the treatment, but also easily leave sequelae

Embodiment Construction

[0038] The technical solutions of the present invention will be further described in detail below in conjunction with the examples.

[0039]When both R1 and R2 are methyl, it is Atractylodes lactone II, and its structural formula is

[0040]

[0041] Verify the present invention by concrete pharmaceutical test below:

[0042] 1. Preparation of test materials

[0043] Atractylodes Ⅱ, dissolved in DMSO.

[0044] 2. Experimental verification process

[0045] ① Platelet aggregation test

[0046] ⑴Preparation of platelets: human-sourced high-concentration platelet plasma, prepared platelet count of 3×10 8 / mL, placed in a 37°C water bath.

[0047] (2) Concentration gradient of Atractylodes Ⅱ compound: In 300uL platelets, the final concentrations of the compounds were 0.1 μm, 0.5 μm, 1 μm, 5 μm, and 10 μm, respectively.

[0048] Compounds were incubated in platelets for 3 min before the experiment started, and resting and DMSO were set as controls in the experiment. Use th...

Abstract

The invention relates to a platelet aggregation resisting drug. The platelet aggregation resisting drug comprises an atractylenolide-II derivative represented by a structural formula 1 shown in specifications. The invention further relates to application of an atractylenolide-II derivative in preparation of the platelet aggregation resisting drug. The platelet aggregation resisting drug, which is simple in composition and is prepared from effective ingredients of natural medicinal raw materials or effective ingredient extracts of the medicinal raw materials, provided by the invention has a good treatment effect, is free from toxic or side effects, is not prone to the generation of tolerance, is convenient to take and is generally applicable to the problems, such as viscous blood and thrombus, caused by too-high platelet aggregation rate.

Description

technical field [0001] The invention relates to the field of medicine, in particular to the preparation and application of atractyloid II derivatives for anti-platelet aggregation. Background technique [0002] Modern medicine believes that there is a certain relationship between the formation of thrombus and the high rate of platelet aggregation. [0003] Thrombus starts from the local coagulation mechanism. After thrombus formation on the surface of hyperarterial intima, the thrombus is covered by proliferating endothelial cells, and the platelets and white blood cells incorporated into the arterial wall thrombus disintegrate to release lipids and other active substances, gradually forming Atheromatous plaque. The latter believes that the disease begins with arterial intima injury, platelet activating factor (PAF) increases, platelets adhere and then aggregate there, followed by fibrin deposition to form microthrombi. After platelets aggregate, some active substances are...
