Description

≪ Desc / Clms Page number 2 > Composition for anti-inflammation containing an extract of Thymus quinquecostatus var. Japnica Hara)

The present disclosure relates to the anti-inflammatory use of isomaltic acid extract.

Inflammation is a complex biological process involving activation of various immune cells such as monocytes / macrophages. Control disorders of the inflammatory immune response cause a variety of pathological conditions, including cancer (Ben-Neriah and Karin, 2011) and metabolic syndrome (Donath and Shoelson, 2011). Macrophages are the major type of cells involved in the inflammatory process by producing a variety of inflammatory mediators such as cytokines / chemokines and nitric oxide (NO) and prostaglandins (PGs) (Zhang and Mosser, 2008). iNOS (inducible NO synthase) is an enzyme that synthesizes NO from L-arginine using NADPH and oxygen molecules (Murakami and Ohigashi, 2007). COX-2 (Cyclooxygenase-2) converts arachidonic acid to prostaglandins such as PGE2 (Aoki and Narumiya, 2012). Control of the reduction of inflammatory mediators in macrophages provides a rationale for the development of therapeutic agents useful in a variety of inflammatory diseases (Murakami and Ohigashi, 2007).

Various transcription factors and cell signaling pathways play a role in the proinflammatory gene expression of macrophages (Guha and Mackman, 2001). Under stimulation by lipopolysaccharides (LPS) or cytokines, NF-κB is activated through activation of the IκB-kinase (IKK) complex. The IKK complex consists of two kinase subunits (IKKα and IKKβ) and the regulatory subunit IKKγ / NEMO. The IKK complex phosphorylates IκBα of Ser32 and Ser36, resulting in ubiquitination followed by proteome degradation (Gloire et al., 2006). Free NF-κB separates from IκBα in the cytoplasm and migrates into the nucleus, activating the transcription of target genes such as proinflammatory genes in the nucleus.

Thyme (Thymus quinquecostatus Celakov) is a perennial deciduous tree belonging to the genus Lepidoptera (Labiatae) originating from the Mediterranean coast of southern Europe and is one of the subtropical and temperate herbivores. In Korea, only thyme thyme ( Thymus quinquecostatus var. Japonica Hara) and two thyme species are native to Japan. In particular, the thyme thyme is native to the Nari Dong Basin, Ulleungdo Island, and is designated as Natural Monument No. 52. It is well- It grows and is known to be easy to cultivate.

Currently, most studies of islet thyme have focused on the study of essential oils and essential oil extracts.

7) detection anti-body (ab) and streptavidin-HRP were diluted with a dilution factor of the protocol in the kit and 100 uL each was dispensed. After incubation at 37 ° C in a CO 2 incubator, For 1 hour.

8) 200 uL aliquots were washed with washing solution 7 times.

9) TMB substrate solution was dispensed in 100 μl aliquots, and the color development was observed in cows.

10) 2N H 2 SO 4 as a stop solution was dispensed in 100 μl aliquots to stop color development.

11) The absorbance (OD) value was measured using a microplate spectrophotometer at a wavelength of 450 nm within 40 minutes after stopping the color development.

The measurement results are shown in FIG. 2 and FIG. The nitrite concentration was measured by the Griess reaction in the cell culture supernatant. The highest nitrite was produced in the LPS (1 ug / mL) - treated group and the thymus thymus As the concentration of extract increased, the nitrite production was decreased statistically. In addition, the concentration of nitrite in the island thyme alone group was similar to that of the untreated group.

PGE2 concentration was measured by ELISA method. As a result, it was found that PGE2 was not produced in the case of the treatment with isothiocyanate alone, but the concentration of PGE2 was increased as the treatment concentration of the island thyme extract was increased LPS alone treatment group.

[Experimental Example 3] Effect of LPS-induced iNOS and COX-2 on Isolation of Thymus Thymus Extract

 To investigate the inhibitory effects of the extracts of thymus thrips on the expression of iNOS and COX-2 in RAW 264.7 cells, pretreatment of thymus thalassemia extract with different concentrations of LPS was carried out for 4 hours for mRNA analysis and 18 hours for protein analysis. (RT-PCR) and Western blot were performed. The primer sequences used for RT-PCR are shown in Table 1.

The measurement results are shown in Fig. As a result, it was confirmed that the expression of mRNA and protein of iNOS and COX-2 induced by LPS was significantly inhibited by the isothiocyanate extract in a concentration-dependent manner. As shown in Experimental Example 2, thymus thymus extract significantly decreased NO and PGE 2 produced by LPS, which was confirmed by the inhibition of iNOS and COX-2 mRNA and protein expression.

[Experimental Example 4] Effect of LPS-induced NF-κB signaling molecule activity on the activity of island thyme extract

In order to confirm whether NF-κB signal transduction pathway is inhibited, LPS was treated for 20 minutes at the concentration of the extract of thymus thymus, and Western blot was performed by extracting the nucleus and cytosol extract.

The results are shown in Fig. As shown in FIG. 5, phosphorylation of NF-κB p65 and p65 migrated into the nucleus when LPS treatment was performed, and it was confirmed that IκBα was degraded. In the case of treatment with the extract of Thymus japonicus at different concentrations, the migration of NF-κB p65 to the nucleus was inhibited and it was observed to inhibit the phosphorylation of p65. In addition, it was confirmed that decomposition of IκBα was remarkably suppressed at a concentration of 20 μM. Thus, the extract of the islet thymus inhibits the expression of iNOS and COX-2 by inhibiting the activity of NF-κB.

[Experimental Example 5] Effect of LPS-induced MAPK activity on the activity of the island thyme extract

 Mitogen-activated protein kinase (MAPK) signaling is activated by several signals such as LPS, which is known to affect the activity of NF-kB and AP-1. There are three kinds of MAPK, ERK, p38, and JNK, which are activated by phosphorylation.

Therefore, the activity of LPS - induced MAPK was tested for the efficacy of the extract. When LPS was treated, the phosphorylation of ERK, p38, and JNK was increased by Western blot. The results are shown in Fig. When thymus extracts were treated in the same manner, LPS - induced phosphorylation of p38 and JNK was inhibited in a concentration - dependent manner. However, phosphorylation of ERK was not inhibited.

Experimental Example 6 Effect of LPS-Induced Thyme Extract on the Production of Pro-inflammatory Cytokine

 TNF-α, one of the cytokines, plays an important role in triggering inflammatory responses by activating T cells and macrophages and by increasing other pro-inflammatory cytokines. Similarly, IL-6, IL-1β is one of the major inflammatory cytokines secreted by macrophages by LPS and is known to always exhibit high levels of inflammation. Finally, we investigated whether thyme extract inhibits TNF-α, IL-6 and IL-1β, which are inflammatory or inflammatory cytokines, in RAW 264.7 cells using ELISA kit and RT-PCR Protein production and mRNA expression were analyzed. The primer sequences of RT-PCR are shown in Table 1.

The results are shown in Fig. It was confirmed by ELISA assay that the protein production of TNF-α, IL-6 and IL-1β was reduced in a concentration-dependent manner in the case of the extract of thymus thymus (FIG. 7A) As shown in FIG. 7B, the expression of TNF-α, IL-6 and IL-1β mRNA was inhibited when the extract of Ishimaki thymus was treated at different concentrations as in the case of protein.
