Description

本発明は医薬品及び健康食品において有用な、炎症性サイトカインTNF-αやIL-6の産生等を抑制し、抗炎症作用を有する薬剤に関する。   The present invention relates to a drug having an anti-inflammatory effect, which suppresses the production of inflammatory cytokines TNF-α and IL-6, which is useful in pharmaceuticals and health foods.

TNF-αやIL-6などの炎症性サイトカインは、病原菌の侵入に対して免疫機能を賦活するなど本来は合目的な機能を有しているが、何らかの原因によって過剰に生産され続けるとリウマチ性関節炎、潰瘍性大腸炎、クローン病、2型糖尿病などさまざまな疾病を引き起こす。そのため、このような病態においてTNF-αなど炎症性サイトカインの生産を抑制する薬剤が開発されており、イブプロフェンやインドメタシン等既存の抗炎症剤の他、サリドマイド誘導体(非特許文献1参照)、ピラゾロン誘導体(非特許文献2参照)、合成クロメン誘導体(非特許文献3参照)、スベリヒユ科植物のアルカロイド(特許文献1参照)、クロモン誘導体(特許文献2参照)、肝実質細胞増殖因子(特許文献3参照)などがあるが、これらの疾病は慢性的な経過をたどることが多く治療は長期化することから、経口摂取が可能で副作用がなく安全な化合物が特に求められている。このような観点から、乳蛋白の断片ペプチド(特許文献4参照)、甘草やショウガの抽出物(特許文献5)、ドコサヘキサエン酸等の高度不飽和脂肪酸(特許文献6,7参照)など食品成分が注目されているが、より活性の強い化合物や当該活性のさらなる増強が必要である。   Inflammatory cytokines such as TNF-α and IL-6 have originally intended functions such as stimulating immune function against the invasion of pathogenic bacteria, but rheumaticity is caused by excessive production for some reason. Causes various diseases such as arthritis, ulcerative colitis, Crohn's disease, and type 2 diabetes. Therefore, drugs that suppress the production of inflammatory cytokines such as TNF-α in such pathological conditions have been developed. In addition to existing anti-inflammatory agents such as ibuprofen and indomethacin, thalidomide derivatives (see Non-Patent Document 1), pyrazolone derivatives (See Non-Patent Document 2), synthetic chromene derivatives (see Non-Patent Document 3), albeloids of the genus Euphorbiaceae (see Patent Document 1), chromone derivatives (see Patent Document 2), hepatocyte growth factor (see Patent Document 3) However, since these diseases often follow a chronic course and treatment is prolonged, there is a particular need for safe compounds that can be taken orally and have no side effects. From this point of view, food components such as milk protein fragment peptides (see Patent Document 4), licorice and ginger extracts (Patent Document 5), highly unsaturated fatty acids such as docosahexaenoic acid (see Patent Documents 6 and 7), and the like. Although attracting attention, there is a need for more active compounds and further enhancement of the activity.

Zinetti et al., Immunology, 86, 416-421, 1995)よりも弱いがイブプロフェンよりは強い。さらにFATAは、炭素数16〜22の不飽和脂肪酸あるいはそのグリセリドまたは低級アルキルエステルを同時に動物細胞に添加すると、それぞれを単独で添加した場合よりも強くTNF-α産生を抑制する。例えばドコサヘキサエン酸を併用した場合、その産生抑制効果はクロルプロマジンに匹敵する効果を示す。FATAはトウモロコシやベニバナの油糧種子に含まれており、ドコサヘキサエン酸も魚油等に含まれる食品成分であるため、これらの組合せになるTNF-α産生抑制剤の安全性は高い。FATAの他、N-(β−フェネチル)フェルラミド(FAPA)、フェルラ酸フェネチルエステル(FAPE)、フェルラ酸3-フェニル-2-プロペニル、カフェイン酸フェネチルエステル、カフェイン酸3-フェニル-2-プロペニル、カフェイン酸フェネチルアミド等、フェルラ酸あるいはカフェイン酸の誘導体はTNF-α産生抑制作用を示し、当該抑制作用はいずれもドコサヘキサエン酸等の炭素数16〜22の不飽和脂肪酸あるいはそのグリセリドまたは低級アルキルエステル添加により増強される。
A representative example of the ferulic acid derivative of the present invention is feruloyltryptamine (FATA), and it was first found by the present inventor that the compound suppresses TNF-α production in animal cells.
This activity itself is weaker than ibuprofen but is weaker than chlorpromazine (M. Zinetti et al., Immunology, 86, 416-421, 1995), which is an existing pharmaceutical and known for its TNF-α inhibitory activity. Furthermore, FATA, when an unsaturated fatty acid having 16 to 22 carbon atoms or a glyceride or lower alkyl ester thereof is simultaneously added to animal cells, suppresses TNF-α production more strongly than when each is added alone. For example, when docosahexaenoic acid is used in combination, the production inhibitory effect is comparable to that of chlorpromazine. Since FATA is contained in oil seeds of corn and safflower, and docosahexaenoic acid is also a food ingredient contained in fish oil and the like, the safety of the TNF-α production inhibitor that combines these is high. In addition to FATA, N- (β-phenethyl) ferramide (FAPA), ferulic acid phenethyl ester (FAPE), ferulic acid 3-phenyl-2-propenyl, caffeic acid phenethyl ester, caffeic acid 3-phenyl-2-propenyl , Ferulic acid or caffeic acid derivatives such as caffeic acid phenethyl amide exhibit TNF-α production inhibitory action, all of which are unsaturated fatty acids having 16 to 22 carbon atoms such as docosahexaenoic acid or their glycerides or lower Enhanced by addition of alkyl ester.

上記バニリン酸誘導体の代表例はバニリン酸3-フェニル-2-プロペニル、プロトカテク酸3-フェニル-2-プロペニル等であり、このようなバニリン酸エステルが、動物細胞におけるTNF-α産生を抑制することは本発明者により初めて見いだされたものであり、また、本作用は炭素数16〜22の不飽和脂肪酸あるいはそのグリセリドまたは低級アルキルエステルの同時添加により増強される。   Representative examples of the vanillic acid derivatives are 3-phenyl-2-propenyl vanillate, 3-phenyl-2-propenyl protocatechuate, etc., and such vanillic acid ester suppresses TNF-α production in animal cells. Was first discovered by the present inventor, and this action is enhanced by the simultaneous addition of an unsaturated fatty acid having 16 to 22 carbon atoms or a glyceride or lower alkyl ester thereof.

上記カルコン誘導体の代表例は2’-ヒドロキシカルコン、4’-ヒドロキシカルコン、4-ヒドロキシカルコン、2−ヒドロキシカルコン、イソリキリチゲニン、キサントフモール、キサントアンゲロール、及びカルコン等であり、カルコン誘導体は、いずれも3〜10μM という低濃度で動物細胞におけるTNF-α産生を抑制し、さらに、炭素数16〜22の不飽和脂肪酸あるいはそのグリセリドまたは低級アルキルエステルとの併用により一層強い抑制作用を示す。
特に、ヒドロキシ基を持たないカルコンやモノヒドロキシカルコンのようなごく簡単な化合物であっても10μMの低濃度において、わずか10μMのドコサヘキサエン酸との共存で、同濃度のクロロプロマジンに匹敵する強力なTNF-α産生抑制作用を示すことは特筆すべきことである。
Representative examples of the chalcone derivatives are 2′-hydroxychalcone, 4′-hydroxychalcone, 4-hydroxychalcone, 2-hydroxychalcone, isoliquiritigenin, xanthohumol, xanthoangelol, and chalcone. All of the derivatives suppress TNF-α production in animal cells at a low concentration of 3 to 10 μM, and further exert a stronger inhibitory effect when used in combination with an unsaturated fatty acid having 16 to 22 carbon atoms or a glyceride or lower alkyl ester thereof. Show.
In particular, even a simple compound such as a chalcone without a hydroxy group or monohydroxychalcone can be compared with chloropromazine at the same concentration in the presence of only 10 μM docosahexaenoic acid at a low concentration of 10 μM. It is noteworthy that TNF-α production is suppressed.

上記したカルコン類のうち、キサントフモールはビールのホップに含まれ、キサントアンゲロールは明日葉に含まれ、イソリキリチゲニンは甘草に含まれ、いずれも従来から喫食されてきたものであり安全性は高い。キサントフモールについての動物における安全性試験のデータ(100mg/Kg・dayの投与でも安全;R. Hussong et al., Mol. Nutr. Food Res., 49, 861-867, 2005)やカルコン自体について急性毒性を示すLD50が500mg/Kg以上の高濃度とされていること(MSDSに収録)から、簡単な構造のカルコンやモノヒドロキシカルコンも通常使用される濃度域では安全性は高いと考えられる。   Of the chalcones described above, xanthohumol is contained in beer hops, xanthoangelol is contained in tomorrow, and isoliquiritigenin is contained in licorice, both of which have been eaten in the past. Safety is high. Data on animal safety studies on xanthohumol (safe for 100 mg / Kg · day administration; R. Hussong et al., Mol. Nutr. Food Res., 49, 861-867, 2005) and the chalcone itself Since LD50, which indicates acute toxicity, has a high concentration of 500 mg / Kg or higher (recorded in MSDS), it is considered that safety is high in the concentration range where normal structures and monohydroxychalcones are also commonly used.

次に、本発明を実施例に基づいてさらに詳細に説明する。
Some of the compounds of the general formula (1) suppress inflammatory cytokines such as TNF-α, and docosahexaenoic acid has already been known to suppress the production of inflammatory cytokines such as TNF-α ( Patent publication 2006-511514, JP-A-2000-159667), combined use of the compound of the above general formula (1) and unsaturated fatty acid such as docosahexaenoic acid, the inflammatory cytokine production inhibitory activity is dramatically improved, and a synergistic effect It has been found for the first time in the present invention.

Next, the present invention will be described in more detail based on examples.

ヒトTHP-1急性単球性白血病細胞(大日本製薬株式会社より購入)を10%の牛胎仔血清(FBS)を含むRPMI-1640培地で前培養後、1 x 105 cells/mlの懸濁液とし、0.1μMのphorbol 12-myristate 13-acetate (PMA) を添加してから0.1mlづつ96-wellプレートに分注した。2日間培養後、細胞がマクロファージ様に分化し底面に張り付いたことを検鏡・確認してから、各ウェルの培地を10μM のドコサヘキサエン酸(DHA、Cayman社製)を加えたかもしくは加えていない10%FBS入り新鮮培地の0.2mlづつに交換した。次いで各ウェルの培地に所定濃度(1〜10mM)のサンプルのエタノール溶液またはエタノールのみを2μl添加し、さらに3時間培養した。次いで、大腸菌細胞膜のリポ多糖(0127:B8、Sigma社製)を32μg/mlの濃度で含むリン酸緩衝液の6μlづつを各ウェルに添加し、20時間培養した。培地を回収し、ELISAキット(Endogen社製)でTNF-α濃度を測定した。培地を回収後ウェルに残った細胞は0.2%クリスタルバイオレット−20%メタノール液で染色し、十分水洗後、1%SDS水溶液の0.1mlづつを各ウェルに加えて色素を溶出させプレートリーダー(595nm)で吸光度を測定して細胞数の指標とした。 Human THP-1 acute monocytic leukemia cells (purchased from Dainippon Pharmaceutical Co., Ltd.) are pre-cultured in RPMI-1640 medium containing 10% fetal bovine serum (FBS) and then suspended at 1 x 10 5 cells / ml After adding 0.1 μM phorbol 12-myristate 13-acetate (PMA), 0.1 ml was dispensed into a 96-well plate. After culturing for 2 days, after confirming that the cells differentiated into macrophages and stuck to the bottom surface, 10 μM docosahexaenoic acid (DHA, Cayman) was added or not added to the medium in each well. The fresh medium containing 10% FBS was replaced with 0.2 ml each. Next, 2 μl of an ethanol solution of a sample having a predetermined concentration (1 to 10 mM) or ethanol alone was added to the medium of each well, and further cultured for 3 hours. Next, 6 μl of a phosphate buffer containing lipopolysaccharide (0127: B8, Sigma) of E. coli cell membrane at a concentration of 32 μg / ml was added to each well and cultured for 20 hours. The medium was collected and the TNF-α concentration was measured with an ELISA kit (Endogen). Cells collected in the well after collecting the medium are stained with 0.2% crystal violet-20% methanol solution, washed thoroughly with water, and 0.1 ml of 1% SDS aqueous solution is added to each well to elute the dye and plate reader (595 nm) The absorbance was measured by using as an index of cell number.

使用したサンプルのうち、Ibp(イブプロフェン、東京化成製)、Cpz,(クロルプロマジン、和光純薬製)、Chal(trans-カルコン、Sigma社製)、2’-OH-Chal(2’-ヒドロキシカルコン、東京化成製)、4’-OH-Chal(4’-ヒドロキシカルコン、和光純薬製)、4-OH-Chal(4-ヒドロキシカルコン、東京化成製)、2-OH-Chal(2-ヒドロキシカルコン、和光純薬製)、Xhum(キサントフモール、Alexis社製)、Isoliq(イソリキリチゲニン、Extrasynthese社製)、Curc(クルクミン、BIOMOL社製)、Ging([6]-ジンゲロール、和光純薬製)、Caps(カプサイシン、和光純薬製)、Rosm(ロスマリン酸、和光純薬製)、CAPE(カフェイン酸フェネチルエステル、和光純薬製)はそれぞれ記載したメーカーから購入した。Xang(キサントアンゲロール)は明日葉の茎、根から文献(小澤 貢ら、薬学雑誌、98、210-214、1978)の方法で抽出、精製、結晶化し、機器分析で構造を確認したものを使用した。   Among the samples used, Ibp (Ibuprofen, manufactured by Tokyo Chemical Industry), Cpz, (Chlorpromazine, manufactured by Wako Pure Chemical Industries), Chal (trans-chalcone, manufactured by Sigma), 2'-OH-Chal (2'-hydroxychalcone, Tokyo Chemical), 4'-OH-Chal (4'-hydroxychalcone, Wako Pure Chemical), 4-OH-Chal (4-hydroxychalcone, Tokyo Chemical), 2-OH-Chal (2-hydroxychalcone) , Wako Pure Chemical), Xhum (Xanthohumol, Alexis), Isoliq (Isolikiritigenin, Extrasynthese), Curc (Curcumin, BIOMOL), Ging ([6] -Gingerol, Wako Pure Chemical) ), Caps (capsaicin, Wako Pure Chemical), Rosm (rosmarinic acid, Wako Pure Chemical), and CAPE (caffeic acid phenethyl ester, Wako Pure Chemical) were purchased from the manufacturers described above. Xang (Xanthoangelol) was extracted, purified and crystallized from stems and roots of tomorrow leaves by the method of literature (Mitsugu Ozawa et al., Pharmaceutical Journal, 98, 210-214, 1978), and the structure was confirmed by instrumental analysis. It was used.

フェルラ酸とバニリン酸の誘導体[N-(β-フェネチル)フェルラミド(FAPA)、フェルロイルトリプタミン(FATA)、フェルロイルチラミン(Fer-Tyr)、β-フェネチルフェルレート(FAPE)、フェルラ酸3-フェニル-2-プロペニル(Fer-oCinn)、N-(β-フェネチル)カフェイン酸アミド(CAPA)、カフェイン酸3-フェニル-2-プロペニル(Caff-oCinn)、N-(3-フェニルプロピル)-4-ヒドロキシ-3-メトキシ安息香酸アミド(Va-nPrPhe)、4-ヒドロキシ-3-メトキシ安息香酸3-フェニル-2-プロペニル(Va-oCinn)、プロトカテク酸3-フェニル-2-プロペニル(Prot-oCinn)、及びシリンガ酸3-フェニル-2-プロペニル(Syr-oCinn)]は特開2005-225872と特願2005-218519において記載した方法で合成した。結果を図1、図2、及び図3に示す。培養液中のサンプルの濃度(μM)は図中に示してある。これらの結果から、フェルラ酸誘導体のFATAやカルコン類並びにクルクミン等各種のフェノール性化合物が図中に表示された範囲で濃度依存的にTNF-αの産生を抑制し、さらに、培地にドコサヘキサエン酸が同時に添加されていると一層強く抑制することがわかる。なお、図1のBに示すように、細胞数の指標となる色素濃度は実験終了後にコントロールとサンプル間で通常10%以下しか違いがなかったことから、TNF-α産生の大きな低下は細胞の逸失によるものではないことが確認された。   Derivatives of ferulic acid and vanillic acid [N- (β-phenethyl) ferramide (FAPA), feruloyltryptamine (FATA), feruloyltyramine (Fer-Tyr), β-phenethylferrate (FAPE), 3-phenyl ferulic acid -2-propenyl (Fer-oCinn), N- (β-phenethyl) caffeic acid amide (CAPA), caffeic acid 3-phenyl-2-propenyl (Caff-oCinn), N- (3-phenylpropyl)- 4-hydroxy-3-methoxybenzoic acid amide (Va-nPrPhe), 4-hydroxy-3-methoxybenzoic acid 3-phenyl-2-propenyl (Va-oCinn), protocatechuic acid 3-phenyl-2-propenyl (Prot- oCinn) and 3-phenyl-2-propenyl syringate (Syr-oCinn)] were synthesized by the methods described in Japanese Patent Application Laid-Open No. 2005-225872 and Japanese Patent Application No. 2005-218519. The results are shown in FIG. 1, FIG. 2, and FIG. The concentration (μM) of the sample in the culture is shown in the figure. From these results, it was confirmed that various phenolic compounds such as ferulic acid derivatives FATA, chalcones and curcumin suppressed TNF-α production in a concentration-dependent manner within the range shown in the figure, and docosahexaenoic acid was added to the medium. It can be seen that the addition is more intense when added simultaneously. As shown in FIG. 1B, the dye concentration, which is an indicator of the number of cells, usually had a difference of only 10% or less between the control and the sample after the experiment was completed. It was confirmed that it was not due to loss.

ドコサヘキサエン酸の代わりにエイコサペンタエン酸(EPA、Cayman社製)とα−リノレン酸(和光純薬製)を用いて実施例1と同様の実験を行なった。結果を図4に示す。この結果から、カルコン類やフェルラ酸誘導体によるTNF-α産生抑制作用がエイコサペンタエン酸やリノレン酸でも増強されることが確認された。   An experiment similar to Example 1 was performed using eicosapentaenoic acid (EPA, manufactured by Cayman) and α-linolenic acid (manufactured by Wako Pure Chemical Industries) instead of docosahexaenoic acid. The results are shown in FIG. From this result, it was confirmed that the TNF-α production inhibitory action by chalcones and ferulic acid derivatives is enhanced by eicosapentaenoic acid and linolenic acid.

フェルラ酸誘導体、カルコン類、及び各種のフェノール性化合物を用いて実施例1と同様の実験を行ない、回収した培地中のインターロイキン6(IL-6)及びインターロイキン1β(IL-1β)の濃度をELISAキット(Endogen社製)で測定した。結果を図5と図6に示すが、これらの炎症性サイトカインの産生もFATAやキサントフモールで抑制され、さらに、この場合もドコサヘキサエン酸を併用すると一層強く抑制されることがわかる。   The same experiment as in Example 1 was performed using ferulic acid derivatives, chalcones, and various phenolic compounds, and the concentrations of interleukin 6 (IL-6) and interleukin 1β (IL-1β) in the collected medium Was measured with an ELISA kit (manufactured by Endogen). The results are shown in FIG. 5 and FIG. 6, and it can be seen that the production of these inflammatory cytokines is also suppressed by FATA and xanthohumol, and in this case, it is further strongly suppressed when docosahexaenoic acid is used in combination.

炎症反応のシグナル分子として一酸化窒素(NO)も重要な役割を果たしており、NOの産生抑制は炎症の抑制につながる。マウスRAW264マクロファージ細胞株(理化学研究所から購入)を10%FBS入りのDMEM培地で前培養し、トリプシン処理で回収して2 x 105 cells/mlの懸濁液とし、0.2mlづつ96-ウェルプレートに植え込んだ。2日間培養後、各ウェルの培地を10μM のドコサヘキサエン酸を加えたかもしくは加えていない10%FBS入り新鮮培地の0.2mlづつに交換した。次いで各ウェルの培地に所定濃度(1〜10mM)のサンプルのエタノール溶液またはエタノールのみを2μl添加し、さらに3時間培養した。次いで、330μg/mlの大腸菌細胞膜リポ多糖(0127:B8、Sigma社製)、3.2μg/mlのアルギニン、及び0.32μg/mlのIFN-γを含む水溶液を6μlづつ各ウェルに添加し、20時間培養した。培地を回収し、培地中でNOから転換生成した亜硝酸イオンをグリース試薬(Sigma社製)で定量した。 Nitric oxide (NO) also plays an important role as a signal molecule of the inflammatory response, and suppression of NO production leads to suppression of inflammation. Mouse RAW264 macrophage cell line (purchased from RIKEN) was pre-cultured in DMEM medium containing 10% FBS, recovered by trypsinization to give a suspension of 2 x 10 5 cells / ml, 96-well in 0.2 ml increments Implanted in a plate. After culturing for 2 days, the medium in each well was replaced with 0.2 ml each of fresh medium containing 10% FBS with or without 10 μM docosahexaenoic acid. Next, 2 μl of an ethanol solution of a sample having a predetermined concentration (1 to 10 mM) or ethanol alone was added to the medium of each well, and further cultured for 3 hours. Next, 6 μl of an aqueous solution containing 330 μg / ml E. coli cell membrane lipopolysaccharide (0127: B8, Sigma), 3.2 μg / ml arginine, and 0.32 μg / ml IFN-γ was added to each well for 20 hours. Cultured. The medium was recovered, and nitrite ions converted from NO in the medium were quantified with a grease reagent (manufactured by Sigma).

また、細胞は実施例1と同様にクリスタルバイオレットで染色し吸光度を測定して細胞数の指標とした。図7のAに示した結果から、フェルラ酸誘導体やカルコン類がLPSで刺激されたマクロファージ細胞におけるNO産生を抑制すること、さらに、ドコサヘキサエン酸が同時に添加されると一層強く抑制することがわかる。なお、図7のBに示すように、細胞数の指標となる色素濃度は実験終了後にコントロールとサンプル間で通常10%以下しか違いがなかったことから、NO産生の大きな低下は細胞の逸失によるものではないことが確認された。   Further, the cells were stained with crystal violet in the same manner as in Example 1 and the absorbance was measured to obtain an index of the number of cells. From the results shown in FIG. 7A, it can be seen that ferulic acid derivatives and chalcones suppress NO production in macrophage cells stimulated with LPS, and further suppress more strongly when docosahexaenoic acid is added simultaneously. Note that, as shown in FIG. 7B, the dye concentration, which is an index of the number of cells, was usually only 10% or less between the control and the sample after the experiment was completed. It was confirmed that it was not a thing.
