Description
본 발명은 PDKs 억제제를 유효성분으로 함유하는 부종, 과민증, 알러지성 비염, 천식, 알러지성 결막염, 알러지성 피부염, 아토피성 피부염, 접촉성 피부염, 두드러기, 소양증, 곤충 알러지, 식품 알러지 및 약품 알러지 등을 포함하는 알러지성 질환의 예방 또는 치료용 약학적 조성물, 화장료 조성물 및 건강 기능 식품에 관한 것이다.The present invention relates to a medicament for the treatment or prophylaxis of edema, hypersensitivity, allergic rhinitis, asthma, allergic conjunctivitis, allergic dermatitis, atopic dermatitis, contact dermatitis, urticaria, pruritus, insect allergies, food allergies and drug allergies containing an PDKs inhibitor as an active ingredient A cosmetic composition and a health functional food for preventing or treating an allergic disease.
비만 세포(mast cells; MC)는 조혈 전구 세포(hematopoietic precursors)로부터 유래된 면역 세포로서 직접적 알러지 반응(immediate-allergic reactions)에 주된 역할을 한다1 -3. 비만 세포에서 고 친화성 IgE 수용체(FcεRI)의 집합(aggregation) 및 뉴로펩티드(neuropeptides)에 의한 자극은 히스타민(histamine), 프로테아제(protease), 새로 합성된 염증 매개 물질(예를 들어, 프로스타글란딘 D2(PGD2), 류코트리엔 C4(LTC4) 및 다양한 사이토카인)과 같은 매개체의 방출을 유발한다4 -7. 비만 세포는 형성된 TNF(tumor necrosis factor)를 저장하는 유일한 세포이며, 형성된 TNF는 빠른 속도로 방출되고 T-세포의 수집과 활성화에 영향을 미친다9 , 10. 비만 세포의 다수의 매개체를 방출할 수 있는 능력은 비만 세포가 주변 환경에 있는 다른 세포들과 활동적인 상호 작용을 할 수 있도록 도와주며, 비만 세포 관련 질병 발생에 참여할 수 있도록 해준다. 종국적으로, 비만 세포의 활성화는 과민증(anaphylaxis), 천식(asthma), 비염(rhinitis), 아토피 피부염(atopic dermatitis) 등 생명을 위협하거나, 직접 알러지 반응을 유발하는 여러 종류의 질병으로 이어질 수 있다3 , 11-15. 따라서, 비만 세포 활성화의 억제는 잠재적 치료법으로 강력히 제시되고 있다. Mast cells (mast cells; MC) has a major role in the direct allergic reaction (immediate-allergic reactions) as immune derived from hematopoietic precursor cells (hematopoietic precursors) cells 1-3. Aggregation of high affinity IgE receptors (FcεRI) and stimulation by neuropeptides in mast cells is associated with histamine, protease, newly synthesized inflammatory mediators (eg, prostaglandin D2 PGD 2), leukotriene C4 (LTC 4) and results in the release of mediators such as various cytokines) 4-7. Mast cells are the only cells that store the formed TNF (tumor necrosis factor), and the formed TNF is released at a rapid rate and affects the collection and activation of T-cells 9 , 10 . The ability of mast cells to release multiple mediators helps mast cells to interact with other cells in the environment and participate in the development of mast cell-related diseases. Ultimately, the activation of mast cells hypersensitivity (anaphylaxis), asthma (asthma), rhinitis (rhinitis), life-threatening, such as atopic dermatitis (atopic dermatitis), or it can lead to several types of diseases that directly cause allergic reactions 3 , 11-15 . Therefore, inhibition of mast cell activation is strongly suggested as a potential treatment.
미토콘드리아 피루브산 탈수소효소(pyruvate dehydrogenase; PDH) 복합체는 문지기 효소(gatekeeping enzyme)로서, 세포 대사에서 구연산 회로(citric acid cycle)와 그 다음 단계인 산화적 인산화 반응을 해당 작용과 포도당 신생 과정을 통해 연결해주는 주요한 역할을 한다16. 이런 효소 활동은 피루브산 탈수소효소 카이나아제(pyruvate dehydrogenase kinases 1-4; PDK1-4)로 촉매화된 E1α 소단위체의 세 개의 세린 잔기(Ser232, Ser293 및 Ser300)에서의 위치 특이성을 지닌 인산화/탈인산 반응을 통해 제어한다. 네 개의 카이나아제는 세 개의 위치에 대하여 각각 다른 반응성을 가지고 있으며, 모든 위치에서의 인산화는 PDH 활동의 제어로 이어진다. 많은 논문에서는 PDH/PDK 시스템의 조절 장애가 암, 신진 대사 질병, 염증 등 여러 질병의 발병 원인이라는 것을 입증하며, PDK가 이러한 질병을 억제할 수 있는 치료의 잠재성을 지닌 부분이라는 의견을 제시했다17-19.The mitochondrial pyruvate dehydrogenase (PDH) complex is a gatekeeping enzyme that binds the citric acid cycle in the cell metabolism and the next step, oxidative phosphorylation, through the glucose uptake process. Play a major role 16 . This enzymatic activity has been shown to have positional specificity at three serine residues (Ser 232 , Ser 293 and Ser 300 ) of the E1 alpha subunit catalyzed by pyruvate dehydrogenase kinases 1-4 (PDK1-4) Phosphorylation / dephosphorylation. Four kinases have different reactivity for each of the three positions, and phosphorylation at all positions leads to the control of PDH activity. Many paper, adjust disabilities arm of PDH / PDK system, and demonstrated that metabolic disease, causes the onset of many diseases, including inflammation, presenting the opinion that part of having a potential treatment that PDK can suppress these diseases 17 -19 .
한편, 디클로로아세테이트(dichloroacetate; DCA)는 많은 질병에 대해 잠재적 치료 효과를 보인 동형 PDK의 일반적인 약물학적 억제제이다20. 예를 들어, DCA는 폐암 또는 유방암과 같은 종양 질환에 대해 체외 및 체내 암 치료제 또는 증감제 역할을 한다고 입증되어 왔다21 -23. 다른 논문은 DCA가 허혈 모델의 심장에서 글루코오스 산화 반응을 자극하여 보호 효과를 나타내었을 뿐만 아니라24, FOXO1을 이용한 PDK4 상향 조절 및 글루코오스 산화 반응을 억제하여, 결과적으로 우심실 비대에서 우심실의 기능을 개선시킨다는 것을 입증했다25. 구체적인 신호 전달 경로는 제시되어 있지 않지만, Marina 등은 천식 마우스 모델에서 DCA가 기도 염증 및 과반응을 억제한다는 사실을 보여주었다26. 최근에 우리 연구진들은 PDK4의 상향 조절이 SMAD1/5/8 인산화를 통해 혈관 석회화의 촉진을 유발한다는 사실과 DCA가 PDK4를 조절함으로써 혈관 석회화를 개선한다는 사실을 보고한 바 있다27. 이에 더하여, DCA로 인한 PDK의 약물학적 억제는 CFA 유발 염증을 억제하여 염증성 통증에서 PDK-젖산 관계의 중요성을 보여주었다28. DCA는 천식 등 많은 질병 모델에서 광범위하게 연구되어 왔지만, DCA가 체외 및 체내 IgE/항원 유발 알러지 반응 모델에서 항알러지 효과가 있는지에 대한 연구는 진행되지 않았다.Dichloroacetate (DCA), on the other hand, is a general pharmacological inhibitor of isoform PDK, which has potential therapeutic effects on many diseases 20 . For example, DCA has been proven that the role the in vitro and vivo cancer or for sensitizing tumor diseases, such as lung or breast cancer 21-23. Another paper by DCA is by stimulating glucose oxidation in the heart ischemia model as well as eoteul indicate a protective effect inhibiting 24, PDK4 up-regulation and glucose oxidation using FOXO1, sikindaneun consequently improve right ventricular function in the right ventricular hypertrophy 25 proved that. Although no specific signaling pathway has been proposed, Marina et al. Have shown that DCA inhibits airway inflammation and hyperactivity in asthmatic mouse models 26 . Recently, our researchers have reported that up-regulation of PDK4 induces the promotion of vascular calcification through SMAD1 / 5/8 phosphorylation and that DCA improves vascular calcification by modulating PDK4 27 . In addition, pharmacological inhibition of PDK caused by DCA is to suppress the CFA-induced inflammation have shown the importance of the lactic acid from inflammatory pain PDK- relationship 28. DCA has been extensively studied in many disease models, including asthma, but no studies have examined whether DCA has antiallergic effects in in vitro and in vivo IgE / antigen-induced allergic response models.

2.1. PDKs 억제제 DCA의 체외에서 BMMC IgE/항원 자극 β-헥소사미니다아제 방출 억제2.1. Inhibition of PDKs Inhibitor DCA In Vitro BMMC IgE / Antigen Stimulation β-Hexosaminidase Emission Inhibition
알러지 유발 항원으로 인해 FceRI에 결합된 특정 IgE의 교차 결합으로 발병된 과민증은 다중 신호 전달 경로 활성화를 유발하여 결과적으로 탈과립, PGD2, 류코트리엔 합성, 그리고 다양한 사이토카인 및 케모카인의 생성을 유발한다30. IgE/항원의 자극으로 인한 MC의 활성화에서 MC의 탈과립은 빠른 속도로 발생하므로, 과립 구성 요소의 방출량을 측정함으로써 그 정도를 파악할 수 있다. 본 발명의 발명자들은 DCA가 BMMC의 탈과립을 억제하는지에 대하여 β-헥소아미니다아제를 IgE/항원 자극으로 하여 조사하였다. 비만 세포 안정제로 널리 알려진 크로몰린이 체외 및 체내에서 비만 세포의 생물학적 역할을 조사하기 위하여 쥐에 사용되어 왔으므로, IgE/항원 자극 BMMC의 β-헥소사미니다아제 방출에서 DCA 또는 크로몰린의 억제 효과를 비교하였다.Hypersensitivity induced by cross-linking of specific IgE bound to FceRI due to allergen induces antigen induces multiple signaling pathways resulting in degranulation, PGD 2 , leukotriene synthesis, and the production of various cytokines and chemokines 30 . In MC activation due to IgE / antigen stimulation, deagglomeration of MC occurs at a rapid rate, so the extent of granule component release can be determined. The inventors of the present invention investigated β-hexa minidase as an IgE / antigen stimulus as to whether DCA inhibits degranulation of BMMC. Since chromolin, widely known as a mast cell stabilizer, has been used in rats to investigate the biological role of mast cells in vitro and in vivo, the inhibitory effect of DCA or cromolyne on the release of? -Hexosaminidase from IgE / Were compared.
도 1에서 보이는 것과 같이, DCA 또는 크로몰린으로 전배양을 시켰을 경우, IgE/항원 활성 BMMC의 β-헥소사미니다아제 방출이 확연히 억제되었으며 흡광도는 IgE/Ag, DCA, 및 크로몰린으로 처리된 BMMC(p<0.0001)에서 각각 1.96±0.06, 0.49±0.02, 및 0.39±0.01로 나타났다. 흥미롭게도, DCA로 인한 β-헥소사미니다아제 방출의 억제 효과는 크로몰린으로 인한 억제 효과와 유사하다.As shown in FIG. 1, when pre-cultured with DCA or chromolin, the release of β-hexosaminidase from the IgE / antigen-active BMMC was markedly inhibited and the absorbance was measured by IgE / Ag, DCA, (p <0.0001) were 1.96 ± 0.06, 0.49 ± 0.02, and 0.39 ± 0.01, respectively. Interestingly, the inhibitory effect of? -Hexosaminidase release due to DCA is similar to the inhibitory effect of cromolyne.
2.2. PDKs 억제제 DCA에 의한 체내에서의 IgE/항원 자극 수동 피부 과민증 억제2.2. Inhibition of IgE / antigen stimulation in the body by PDKs inhibitor DCA and inhibition of passive skin hypersensitivity
DCA는 항당뇨병 및 지질저하 효과31뿐만 아니라, 심근 및 뇌혈관 허혈에 대한 잠재적 치료 효과32 , 33도 있으며, 잠복기 및 임상의 후천적34 , 35 및 선천적36 - 38 형태의 유산 산증에 대해 효과가 있는 것으로 보고되어 왔다. DCA가 나트륨염의 형태로 구강 투여된 경우, 빠른 속도로 흡수되어 생체 이용 가능성을 보이고 첫 번째 12.5-50mg/kg DCA 구강 투여의 플라스마 반감기가 최대 1시간이다32 ,39. 모노카복실레이트 및 피루빈산염 운반 시스템으로 각각 플라스마 및 미토콘드리아 세포막을 통과하여 혈액 뇌관문과 미토콘드라이의 농도를 지나간다. 마우스의 귀에 IgE/항원 자극 PCA 반응이 유발되면, 해당 마우스에 에반스 블루 용액을 투여함으로서 피부 내 혈관의 삼투압 증가로 인한 과도 혈관외 유출 및 유출량을 쉽게 모니터링할 수 있다40,41. 즉, PCA는 알러지 유발 항원에 대한 감도 및 해당 반응 개선 효과 연구에 사용될 수 있다.DCA is an antidiabetic and hypolipidemic effect 31, as well as cardiac and cerebrovascular ischemia potential therapeutic effects 32, 33 also are on, the incubation period and the acquired 34, 35 and born 36 clinical - that is effective for the 38 form lactic acidosis . When DCA is orally administered in the form of a sodium salt, it is rapidly absorbed and bioavailable, and the plasma half-life of the first 12.5-50 mg / kg DCA oral administration is up to 1 hour 32 , 39 . Monocarboxylate and pyruvate delivery systems pass plasma and mitochondrial membranes, respectively, to pass through blood primers and mitochondrion concentrations. When IgE / antigen-stimulated PCA reaction is induced in the mouse's ear, the Evans blue solution can be easily administered to the mouse to monitor the transient extravasation and efflux due to increased osmotic pressure in the skin 40,41 . In other words, PCA can be used to study sensitivity to allergen-induced antigens and their response improvement.
IgE/항원 자극 수동 피부 과민증 마우스를 이용하여 DCA 또는 크로몰린의 항 알러지 효과를 살펴보았다. β-헥소사미니다아제 방출 분석의 체외 효과와 동일하게, DCA로 치료한 마우스는 에반스 블루 혈관외 유출의 뚜렷한 감소를 보였다(도 2A 및 도 2B, p < 0.0001). 더 흥미로운 것은, DCA로 인한 에반스 블루 혈관외 유출의 억제 효과는 크로몰린으로 인한 것보다 우수하였다. 에반스 블루 용액의 삼출량은 매개체, DCA, 및 크로몰린으로 치료한 쥐에서 각각 5.02±1.01, 1.14±0.45, 및 1.78±0.58이었다.Anti-allergic effects of DCA or cromolyn were examined using IgE / antigen-stimulated passive skin hypersensitivity mice. Similar to the in vitro effect of the β-hexosaminidase release assay, mice treated with DCA showed a significant reduction in Evans blue extravasation (FIGS. 2A and 2B, p <0.0001). More interestingly, the inhibitory effect of DCA on Evans blue extravasation was superior to that due to chromolin. The excretion of Evans blue solution was 5.02 ± 1.01, 1.14 ± 0.45, and 1.78 ± 0.58 in the rats treated with vehicle, DCA, and cromolyn, respectively.
본 발명은 PDKs 억제제인 DCA가 IgE/항원 활성 BMMC의 β-헥소사미니다아제 방출에 대한 억제 효과가 있다는 것을 처음으로 입증했으며, 그 억제 효과가 크로몰린과 비교하여 유사 내지 우수하다는 사실도 보여주었다. 그러므로, 본 발명의 발명자들은 DCA를 이용한 치료가 IgE/항원 유발 수동 피부 과민증을 성공적으로 억제시키며, 그 효과가 크로몰린을 비교 가능하다는 사실을 확인하였다. 체외 및 체내 IgE/항원 자극 PCA 모델에서 DCA를 매개체로 이용한 항알러지 효과에 대한 신호 전달 경로를 밝히는 시도가 추후에 이루어져야 할 것이다. 더 나아가, 본 연구를 통하여 새로운 DCA 유도체를 잠재적 항알러지 의약품으로 개발시킬 수 있는 근거가 되었다.The present invention demonstrated for the first time that the PDKs inhibitor DCA has an inhibitory effect on the β-hexosaminidase release of IgE / antigen-activated BMMCs, and that the inhibitory effect is similar or superior to that of chromolin . Therefore, the inventors of the present invention have confirmed that treatment with DCA successfully inhibits IgE / antigen-induced passive skin hypersensitivity and that the effect is comparable to chromolin. In the in vitro and in vivo IgE / antigen-stimulated PCA model, attempts to elucidate signaling pathways for anti-allergic effects using DCA as a mediator should be made in the future. Furthermore, this study has provided a basis for developing new DCA derivatives as potential antiallergic drugs.
