Description
본 발명은 나르도시논 계열 대사체를 함유하는 항염증 조성물에 관한 것으로, 보다 상세하게는 감송향 메탄올 추출물의 헥산 분획물로부터 분리될 수 있는 나르도시논(Nardosinone), 이소나르도시논(Isonardosinone), 칸숀 E(Kanshone E) 또는 칸숀 B(Kanshone B)를 함유하는 항염증 약학적 조성물, 화장품 조성물 및 식품 조성물에 관한 것이다.The present invention relates to an anti-inflammatory composition containing a narcondanone-based metabolite, and more particularly, nardosinone, isonardosinone, which can be separated from the hexane fraction of the extract of persimmon fragrance. An anti-inflammatory pharmaceutical composition, cosmetic composition and food composition containing Kanshone E or Kanshone B.
염증성 질환이란 세균의 침입에 의해 형성되는 농양의 병리적 상태를 의미한다. 대표적인 염증성 질환으로는 골관절염, 류마티스 관절염, 통풍, 강직성 척추염, 건염, 건막염, 류마티스 열, 루프스, 섬유근통(Fibromyalgia), 건선 관절염, 천식, 아토피, 크론병, 궤양성 대장염 등 급성 만성 염증질환 등이 있다. 염증은 물리적인 외상, 유해한 화학물질, 미생물에 의한 감염이나 생체 내 대사산물 중의 자극성 물질에 의하여 야기되는 조직손상에 대하여 국소적으로 나타나는 정상적이고 보호적인 생체 내 방어기전의 발현이다. Inflammatory disease refers to the pathological condition of an abscess formed by the invasion of bacteria. Representative inflammatory diseases include acute chronic inflammatory diseases such as osteoarthritis, rheumatoid arthritis, gout, ankylosing spondylitis, tendinitis, tendonitis, rheumatic fever, lupus, fibromyalgia, psoriatic arthritis, asthma, atopic dermatitis, Crohn's disease, ulcerative colitis, etc. have. Inflammation is a manifestation of normal and protective in vivo defense mechanisms that are localized to tissue damage caused by physical trauma, harmful chemicals, microbial infections or irritants in metabolites in vivo.
생체에 있어서 염증의 발생에는 다양한 생화학적인 현상이 관여하고 있다. 대식세포(Macrophage)는 다양한 기능을 가진 세포로 화학적 자극에 의하여 여러 가지 사이토카인(cytokine)과 질소산화물(NO)을 생성하여 염증반응에서 중요한 역할을 한다. 특히, 대식세포에서 인터페론-감마(Interferons-γ, IFN-γ)와 같은 사이토카인 자극에 의해 발현되는 유도성 질소산화물 합성효소(iNOS)는 장시간 동안 다량의 질소산화물(NO)을 생산한다. 이러한 산화적 스트레스는 IκB에 의하여 억제되어 있는 염증 반응의 전사인자인 NF-κB활성을 촉진시키는 것으로 알려져 있다. 활성화된 NF-κB는 핵으로 이동하여 iNOS, COX-2 및 IL-1β나 TNF-α와 같은 여러 종류의 사이토카인 등 염증반응을 유도하는 유전자 발현을 촉진시키는 것으로 알려져 있으며, 이들 인자들을 저해하면 염증 반응이 억제되는 것으로 알려져 있다(Baeuerle et al., Annu. Rev. Immunol., 12:141-179, 1994).Various biochemical phenomena are involved in the development of inflammation in the living body. Macrophage is a multi-functional cell that plays an important role in the inflammatory response by generating various cytokines and NOx by chemical stimulation. In particular, inducible nitric oxide synthase (iNOS) expressed by cytokine stimulation such as interferons-gamma (IFN-γ) in macrophages produces large amounts of nitric oxide (NO) for a long time. This oxidative stress is known to promote NF-κB activity, a transcription factor of the inflammatory response inhibited by IκB. Activated NF-κB is known to promote the expression of genes that induce inflammatory responses, such as iNOS, COX-2, and various cytokines such as IL-1β or TNF-α. Inflammatory responses are known to be inhibited (Baeuerle et al., Annu. Rev. Immunol., 12: 141-179, 1994).
염증유발물질 중 하나인 NO는 정상상태에서는 내피세포나 대식세포에서 생산되며 세포살상과 살균작용 이외에도 다양한 생리활성을 나타내는데, 특히 혈관 내피세포의 이완작용에 있어서 혈압의 항상성(homeostasis)을 유지하는 역할을 하는 것으로 알려져 있다. LPS(lipopolysaccharide), 염증유발인자 및 방사선조사 등의 자극은 특히, 유도형 산화질소 합성효소인 iNOS의 발현을 유도하여 많은 양의 NO를 4 내지 6 시간 동안 계속적으로 생성시키는데 이와 같이 생성된 과도한 양의 NO는 상기와 같은 염증성 질환들을 유발한다. NO, one of the inflammatory substances, is produced in endothelial cells or macrophages in a normal state and exhibits various physiological activities in addition to cell killing and bactericidal action. In particular, it plays a role in maintaining homeostasis of blood pressure in the relaxation of vascular endothelial cells. It is known to do. Stimulation of lipopolysaccharide (LPS), pro-inflammatory factors, and irradiation, in particular, induces the expression of iNOS, an inducible nitric oxide synthase, continuously producing large amounts of NO for 4-6 hours. NO causes such inflammatory diseases.
이러한 염증 질환을 치료하기 위한 가장 일반적인 염증성 질환 예방 또는 치료제는 크게 스테로이드성 및 비스테로이드성 염증성 질환 예방 또는 치료제로 구분되며, 이중 대부분의 합성 염증성 질환 예방 또는 치료제는 주작용 이외에 여러 가지 부작용을 수반하는 경우가 많으므로 효과가 탁월하며 부작용이 적은 염증성 질환 예방 또는 치료제의 개발이 절실히 요구되고 있는 실정이다. 특히, 효능 및 부작용 측면에서 볼 때, 예로부터 임상적 경험이 풍부하고 안전성 측면에서 탁월한 평가를 받고 있는 천연물 제제가 염증 질환의 예방 및 치료제 개발에 있어 좋은 후보물질이 될 것으로 여겨진다.The most common inflammatory disease prevention or treatment for treating such inflammatory diseases is divided into steroidal and nonsteroidal inflammatory disease prevention or treatment, and most of the synthetic inflammatory disease prevention or treatment has several side effects in addition to the main action. In many cases, excellent effects and development of drugs for preventing or treating inflammatory diseases with fewer side effects are urgently needed. In particular, in terms of efficacy and side effects, natural product formulations, which have a long history of clinical experience and excellent evaluation in terms of safety, are considered to be good candidates for the development of preventive and therapeutic agents for inflammatory diseases.
감송향(Nardostachys jatamansi)은 전통적으로 위통, 위장경련, 흉복장만, 신경성 위장병, 구토, 두통, 각기 등에 사용되며, 몇몇 아시아 국가들에서 강장제, 자극제 및 항경련제로 광범위하게 사용되었을 뿐 아니라, 간질, 병적 흥분, 심계 항진 및 경련을 치료하는데도 사용되어 왔다(Bagchi, A., 등, Planta Med., 57, 9697 (1991)). Nardostachys jatamansi is traditionally used for stomach pain, gastrointestinal spasms, chest pain, neurological gastrointestinal disorders, vomiting, headaches, and the like, and has been used extensively as a tonic, irritant and anticonvulsant in several Asian countries.

P-ERK, p-JNK, p-38, a type of mitogen activated protein kinase (MAPKs) for inflammatory responses induced by lipopolysaccharide (LPS) in BV2 cells, mouse-derived microglia In order to confirm the expression inhibition pathway, the method of the literature (Kim et al., European Journal of Pharmacology, 721, pp. 267-276, 2013) and the Western blot analysis of Example 5 were tested.
BV2 세포에 나르도시논 계열 대사체를 20, 40, 80 μM로 3시간 전처리 한 후 리포폴리싸카라이드로 염증 반응 경로 유발하고, 1시간 동안 5% 이산화탄소 배양기 내에서 배양 후 p-ERK, p-JNK 및 p-38의 발현을 확인하였다.After pretreatment with narcionine-based metabolites to BV2 cells for 3 hours at 20, 40, 80 μM, induce inflammatory reaction pathways with lipopolysaccharide, and incubate in 5% carbon dioxide incubator for 1 hour and then p-ERK, p- Expression of JNK and p-38 was confirmed.
도 8 내지 10에 나타낸 바와 같이, LPS를 처리하였을 때 증가하였던 p-JNK(도 8), p-ERK(도 9), p-38(도 10) 발현이 나르도시논 계열 대사체를 농도별 처리하면 발현이 감소하는 것을 확인하였다.As shown in FIGS. 8 to 10, p-JNK (FIG. 8), p-ERK (FIG. 9), and p-38 (FIG. 10) expressions increased when LPS was treated. It was confirmed that expression decreased with treatment.
따라서 나르도시논 계열 대사체의 염증 억제는 미토겐 활성 단백질 키나아제 (MAPKs, mitogen activated protein kinase)의 종류인 p-JNK, p-ERK, p-38 경로의 인산화를 억제함으로써 나타난다는 것을 확인하였다.Therefore, it was confirmed that the inhibition of nardonone-based metabolites was suppressed by the phosphorylation of p-JNK, p-ERK and p-38 pathways, which are a type of mitogen activated protein kinase (MAPKs).
