Embodiment 1

[0021] Example 1: Human THP-1 mononuclear cell line was purchased from Shanghai Cell Bank, Chinese Academy of Sciences. THP-1 cells were cultured in 1640 medium (containing 10% FBS, 1% penicillin and streptomycin) at 37°C, 5% CO 2 cultured in an incubator. THP-1 mononuclear cells in the logarithmic growth phase were evenly spread into six-well plates (1×105 / ml) and cultured for 12 hours. Add 2ml of medium containing phorbol ester (100nM) to THP-1 mononuclear cells for induction for 48h; add 2ml of medium containing icolin A respectively, set up 4 concentration gradients (5, 10, 20, 40μM); 1h Afterwards, 2 ml of culture medium containing ox-LDL (20 μg / ml) was added and induced for 12 hours; RNA of THP-1 cells was isolated, and mRNA expression was measured by real-time quantitative PCR.

[0022] Conclusion: if figure 2 As shown, after incubation with Ox-LDL, the expressions of IL-1, TNF-α and IL-6 mRNA in THP-1 cells were significantly increased, and the levels of IL-1 and T...

Embodiment 2

[0023] Example 2: 20 ApoE knockout mice were randomly divided into two groups (n=10). After adapting to feeding for a week, feed high-fat feed. The mice in the test group were given 12 mg / kg / d of icolin A (Ilexin A dissolved in 0.5% CMC-Na aqueous solution) by intragastric administration; the mice in the model group were given an equal volume of 0.5% CMC-Na aqueous solution by intragastric administration for 16 weeks. In the blank group, 10 C57BL / 6J mice were fed with high-fat diet and fed with equal volume of 0.5% CMC-Na aqueous solution for 16 weeks. The mice were sacrificed and the aorta was taken to make slices, stained with H&E, and the area of ​​aortic plaque was observed under a light microscope.

[0024] Conclusion: if image 3 As shown, compared with the model group, the aortic atherosclerotic lesion area of ​​mice in the hollylin A intervention group was significantly reduced.

Embodiment 3

[0025] Example 3: Preparation of Capsules IlexgeninA 25g, starch 75g, thoroughly mix the dried starch and IlexgeninA, pass through a 120-mesh sieve, and mix thoroughly to prepare capsules, each containing 50mg of IlexgeninA.

Abstract

The invention relates to the technical field of medicines and particularly discloses application of ilexgenin A in preparation of anti-atherosclerosis drugs. The research finds that ilexgenin A has a good effect on resisting atherosclerosis, and can obviously inhibit the formation of foamed cells in a certain concentration range. The whole experiment shows that ilexgenin A has an improvement effect on Apo E<- / -> mice atherosclerosis. Compared with the existing anti-atherosclerosis drugs, the drug prepared from ilexgenin A has the advantages of high efficiency, multiple targets and low toxic and side effects.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to the anti-atherosclerosis activity of Ilexgenin A and the new application of Ilexgenin A in preparing anti-atherosclerosis drugs. Background technique [0002] In my country, cardiovascular and cerebrovascular diseases caused by atherosclerosis rank first and have become the main cause of death of cardiovascular and cerebrovascular diseases. [0003] IlexgeninA is an ursane-type triterpene derivative, which was first found in Ilex pubescens Hook.et.Arn. It has a higher content in holly plants and is the main characteristic component of mountain green tea (JohjiYamahara et al. Photochemistry, 1987, 26 (7): 2023-2027). We previously reported that it has a good improvement effect on non-alcoholic fatty liver in rats (Wei-xi Cui, Jing-Jing Li et al. Drug Development Research, 2013,74(4):227-236); in addition, we found that IlexgeninA has a certain antibacterial effect (Xiao-QingChe...
