Problems solved by technology

Salicornia saponin A is a norpentacyclic triterpene saponin isolated from the whole herb of Salicornia, and it has a killing effect on human leukemia cells HL-60 and human liver cancer cells HepG2, and can be used to prepare antineoplastic drugs ( 3. Shan Yu, patent application number: 201110262116.9), but the effect of salicornia saponin A on inflammation has not been reported

Embodiment 1

[0019] Example 1 Cytotoxicity Test of Salicornia saponin A

[0020] The cytotoxicity of salicornia saponin A was detected by MTT method, and the specific steps were as follows:

[0021] RAW264.7 cells (2×10 5 cells / well) were inserted into 96-well culture plates and cultured overnight, and different concentrations of salicordin A (1, 2, 4, 6, 8, 10 μg / ml, DMSO was used as a blank control) were added for 24 hours, and then Add MTT to a final concentration of 0.5 mg / ml for 4 hours, add DMSO at 100 μl / well, shake for 15 minutes, and read the absorbance at a wavelength of 570 nm.

[0022] OD 570 Can reflect the growth of cells, according to OD 570 Calculate the cell viability to judge whether salicordin A has cytotoxicity.

[0023] The results of the MTT method showed that (see figure 2 ): Salicordin A has basically no cytotoxicity to RAW264.7 cells at a concentration of 1-10 μg / ml.

Embodiment 2

[0024] Example 2 Salicordin A inhibits prostaglandin E 2 (PGE 2 )effect

[0025] Mouse macrophages RAW264.7 in the logarithmic growth phase were spread on 24-well plates, adhered to the wall overnight, added saponin A or positive control indomethacin, and 100 ng / ml LPS was added for 24 hours after 2 hours. Collect the cell culture fluid, 1000g, 15min, use the competitive ELISA method to detect the prostaglandin E in the supernatant 2 . see results image 3 .

[0026] Compared with the LPS-induced inflammation model group, after administration of salicordin A, LPS induced prostaglandin E secreted by mouse macrophage RAW264.7 2 Significantly reduced, and showed a good dose-dependent.

Embodiment 3

[0027] Example 3 Salicordin A inhibits the action of inflammatory factor nitric oxide (NO)

[0028] RAW264.7 cells (1×10 6 Cells / mL) were inserted into 96-well culture plates and cultured overnight, then different concentrations of salicordin A (0.1, 1, 10 μg / ml, DMSO was used as blank control), and then 100 ng / ml LPS was added to stimulate After 24 hours, the cell culture supernatant was collected, and the content of nitric oxide (NO) was detected by the Griess method.

[0029] Experimental results (see Figure 4 ) showed that: Salicornia saponin A can inhibit bacterial lipopolysaccharide-induced nitric oxide production in RAW264.7 cells in a dose-dependent manner.

Abstract

The invention belongs to the field of natural drug, and relates to applications of specific monomer bigelovii A in Salicornia bigelovii Torr. in preparing drug compositions, and especially in preparing drug compositions used for preventing and treating inflammatory diseases. It is shown by in vitro inflammation model experiments that bigelovii A is capable of inhibiting generation of inflammatory induced prostaglandin E2 and release of nitric oxide; it is fond by in vivo experiments on animals that bigelovii A is capable of inhibiting phorbol ester induced mouse ear swelling; and it is confirmed by experiments that bigelovii A possesses obvious anti-inflammatory action on inflammatory diseases, and can be used for preparing drugs used for preventing and treating inflammatory diseases, wherein the inflammatory diseases include acute lung injury, rheumatic arthritis, inflammatory bowel disease, neurodegenerative disease, and septic shock.

Description

technical field [0001] The invention relates to the field of natural medicines, in particular to the application of a specific monomer salicornia saponin A (Bigelovii A) in the preparation of pharmaceutical compositions, especially in the preparation of pharmaceutical compositions for preventing and treating inflammation-related diseases. application. Background technique [0002] Inflammatory response is one of the important components of the body's immune system, which is precisely regulated by the body through various channels. However, when the inflammatory response is uncontrollable, it will lead to a variety of diseases in the body, such as acute lung injury (acute lung injury), rheumatoid arthritis (rtheumatoid arthritis), inflammatory bowel disease (Inflammatory bowel disease, IBD), neurodegenerative Disease (neurodegenerative disorder) and septic shock (septic shock syndrome), etc., long-term inflammatory response stimulation can also induce body cancer (1, Zhu et ...
