Description

本発明は血小板活性化因子アセチルヒドロラーゼ機能調整剤に関し、更に詳細には、アンドログラホリドを含有し、生体内での細胞質から細胞の膜への血小板活性化因子アセチルヒドロラーゼの移行の促進や、酸化ストレス抵抗性を改善するなどの作用を有する血小板活性化因子アセチルヒドロラーゼ機能調整剤およびこれを含有する外用剤ないし経口用組成物に関するものである。   The present invention relates to a platelet activating factor acetylhydrolase function regulator, and more particularly, andrographolide, which promotes the transfer of platelet activating factor acetylhydrolase from the cytoplasm to the cell membrane in vivo and is oxidized. The present invention relates to a platelet activating factor acetylhydrolase function regulator having an action such as improving stress resistance, and an external preparation or oral composition containing the same.

紫外線、環境汚染などの外的因子によって活性酸素が発生すると、過酸化脂質が作られることはよく知られている。この過酸化脂質は、炎症、老化、色素異常症などの様々な老化現象を引き起こすことも明らかとなってきた。そこで、このような老化現象を防止する目的で皮膚外用剤においては、ビタミンC、ビタミンEなどの抗酸化物質を用いて、過酸化脂質の形成を未然に防ぐという予防的な方策がとられてきた。しかし、いったん形成された過酸化脂質に対する対処法については、検討が進んでいないのが現状である。   It is well known that lipid peroxide is produced when active oxygen is generated by external factors such as ultraviolet rays and environmental pollution. It has also been revealed that this lipid peroxide causes various aging phenomena such as inflammation, aging, and dysplasia. Therefore, in order to prevent such an aging phenomenon, in the preparation for external use of skin, a preventive measure has been taken to prevent the formation of lipid peroxide by using antioxidant substances such as vitamin C and vitamin E. It was. However, the current situation is that studies have not been made on how to cope with lipid peroxides once formed.

先に本発明者らは、生体には本来、これら過酸化脂質の害から生体を防御する為の様々な抗酸化機構が備わっていることに着目し検討した結果、これら生体内での抗酸化機構は加齢とともに低下し、活性酸素やフリーラジカル、紫外線照射等の酸化ストレスによる障害の修復に対して充分に対処できなくなり、障害が蓄積することを見出した。そして、過酸化脂質による皮膚障害の原因に血小板活性化因子アセチルハイドロラーゼという酵素の働きが大きく関与していることを突き止め、この酵素の活性を調整する剤を見出し、特許出願している(特許文献1参照)。   The inventors of the present invention have previously studied paying attention to the fact that the living body is originally provided with various antioxidant mechanisms for protecting the living body from the damage of these lipid peroxides. The mechanism declined with aging, and it was found that it was unable to cope with the repair of damage caused by oxidative stress such as active oxygen, free radicals, and ultraviolet irradiation, and the damage accumulated. And we found out that the action of an enzyme called platelet activating factor acetylhydrolase is greatly involved in the cause of skin damage caused by lipid peroxide, and found an agent that regulates the activity of this enzyme, and have applied for a patent (patent) Reference 1).

また、本発明者らは、血小板活性化因子アセチルヒドロラーゼが、生体膜の構成成分であるリン脂質のうち、過酸化された部位を特異的に取り除く働きがあること、つまり過酸化脂質による障害を修復すること、また、その機能が細胞の生命維持に重要であること、さらに、加齢につれて過酸化脂質修復機能が低下することを報告している(非特許文献1参照。)

In addition, the present inventors have shown that the platelet activating factor acetylhydrolase has a function of specifically removing a peroxidized site from phospholipids that are constituents of biological membranes, that is, the disorder caused by lipid peroxide. It has been reported that repairing, the function of which is important for maintaining the life of cells, and that the lipid peroxide repairing function decreases with age (see Non-Patent Document 1).

しかしながら、血小板活性化因子アセチルヒドロラーゼが、上記活性を奏するためには、この酵素が生体膜に到達し、その構成成分であるリン脂質の過酸化された部位を特異的に取り除くことが必要であり、細胞質から細胞の膜への移行を促進させる手段の開発が求められている。   However, in order for the platelet activating factor acetylhydrolase to exert the above-mentioned activity, it is necessary for this enzyme to reach the biological membrane and specifically remove the peroxidized site of its constituent phospholipid. There is a need for the development of means to promote the transition from the cytoplasm to the cell membrane.

本発明者らは、上記した血小板活性化因子アセチルヒドロラーゼの作用に着目し、この酵素の機能を調整し、皮膚などに適用した場合にその細胞質から細胞の膜への移行を促進しうる化合物を検索していたところ、アンドログラホリドという物質が優れた効果を有することを見出し、本発明を完成した。   The present inventors paid attention to the action of the above-mentioned platelet activating factor acetylhydrolase, adjusted the function of this enzyme, and added a compound that can promote the transition from the cytoplasm to the cell membrane when applied to the skin or the like. As a result of searching, it was found that a substance called andrographolide had an excellent effect, and the present invention was completed.

すなわち本発明は、アンドログラホリドを有効成分とすることを特徴とする血小板活性化因子アセチルヒドロラーゼ機能調整剤を提供するものである。   That is, the present invention provides a platelet activating factor acetylhydrolase function regulator characterized by comprising andrographolide as an active ingredient.

また本発明は、血小板活性化因子アセチルヒドロラーゼ機能調整剤を含有する外用剤および経口用組成物を提供するものである。   The present invention also provides an external preparation and an oral composition containing a platelet activating factor acetylhydrolase function regulator.

本発明によれば、アンドログラホリドの作用により、生体中での血小板活性化因子アセチルヒドロラーゼ(以下、「PAFアセチルヒドロラーゼ」と略すことがある)の機能を調整することができ、細胞内でPAFアセチルヒドロラーゼの細胞質から細胞の膜への移行を促進することができる。また、アンドログラホリドは生体内での酸化ストレス抵抗を改善することができる。   According to the present invention, the function of platelet activating factor acetylhydrolase (hereinafter sometimes abbreviated as “PAF acetylhydrolase”) in the living body can be adjusted by the action of andrographolide, and PAF can be intracellularly regulated. The transfer of acetyl hydrolase from the cytoplasm to the cell membrane can be facilitated. Andrographolide can improve oxidative stress resistance in vivo.

以下、本発明について詳細に説明する。
本発明において、有効成分として用いるアンドログラホリドは、下記式(1)で示される既知の化合物である。

Test example 1
Assessment of PAF acetylhydrolase translocation from cytoplasm to cell membrane:
Human neonatal skin-derived fibroblasts are cultured for 5 days in Dulbecco's modified Eagle medium (manufactured by Nissui) containing 10% fetal bovine serum. Then, 1 μg / mL of andrographolide (Note 1) or 5 μg / mL of catechin is added, and after culturing for 24 hours, t-butyl hydroperoxide (manufactured by Sigma) is added. After further incubation for 3 hours, the cells were collected and disrupted. The cell lysate is ultracentrifuged at 100,000 × g for 60 minutes, and fractionated into a cytoplasmic fraction and a membrane fraction. These fractions were electrophoresed by SDS-PAGE, PAF acetylhydrolase was detected by Western blotting, and the amount of protein in each fraction was quantified. From the ratio of the amount of PAF acetylhydrolase protein in the cell membrane fraction to the cytoplasmic fraction (the amount of protein in the cell membrane fraction / the amount of protein in the cytoplasm fraction), the PAF acetylhydrolase from the cytoplasm to the cell membrane Migration was evaluated. The results are shown in Table 1.
* Note: Andrographolide is manufactured by Calbiochem
(Purity 95% or more) was used as it was.

試 験 例 2
酸化ストレス抵抗性の測定方法:
ヒト新生児皮膚由来線維芽細胞を10%牛胎児血清含有ダルベッコ変法イーグル培地(ニッスイ社製)にて培養し、ほぼコンフルエントになったところで、試験例1で用いたのと同じアンドログラホリド 1μg/mL又はカテキン 5μg/mLを添加し、24時間培養した。その後、t−ブチルヒドロペルオキシド(シグマ社製)を0〜800μM添加し、更に4時間培養し、MTTアッセイで細胞生育率を測定した。この結果を図1に示した。
Test example 2
Method for measuring oxidative stress resistance:
Human neonatal skin-derived fibroblasts were cultured in Dulbecco's modified Eagle medium (produced by Nissui) containing 10% fetal bovine serum. mL or catechin 5 μg / mL was added and cultured for 24 hours. Thereafter, t-butyl hydroperoxide (manufactured by Sigma) was added in an amount of 0 to 800 μM, further cultured for 4 hours, and the cell growth rate was measured by MTT assay. The results are shown in FIG.

表1及び図1より、抗酸化剤として汎用されているカテキンを使用した場合とアンドログラホリドを使用した場合の比較では、カテキンを使用した場合では細胞の酸化ストレスに対する抵抗性を上げることができなかったのに対し、アンドログラホリドを使用した場合はPAFアセチルハイドロラーゼの細胞の膜への移行を高めることで酸化された膜を修復し、酸化ストレス抵抗性を高めることが確認された。   According to Table 1 and FIG. 1, when using catechin, which is widely used as an antioxidant, and using andrographolide, the resistance to oxidative stress of cells can be increased when catechin is used. On the other hand, when andrographolide was used, it was confirmed that the oxidized membrane was repaired by enhancing the transfer of PAF acetylhydrolase to the cell membrane, and the resistance to oxidative stress was increased.

試 験 例 3
酸化ストレス抵抗性の測定方法:
試験例2と同様の酸化ストレス抵抗性の測定を、ヒト肝細胞由来のHepG2細胞を用いて行った。まず、HepG2細胞を96穴マイクロプレートに、各ウエルあたり2.5×10細胞(100μl)で分注し、定着させた。次いで、各ウエルに試験例1で用いたのと同じアンドログラホリドを最終濃度が6.3μMとなるようにして25μl添加し、さらに44時間培養を行った。その後、過酸化化合物であるt−ブチルヒドロペルオキシド(t-butyl hydroperoxide:t−BHP)を最終濃度が0〜1mMとなるように添加し、3時間後の細胞生存率を測定した。この結果を図2に示した。なお、細胞生存率はWST−1染色法を用いて、t−BHP無添加対照を100%として算出した。
Test example 3
Method for measuring oxidative stress resistance:
The measurement of oxidative stress resistance similar to Test Example 2 was performed using HepG2 cells derived from human hepatocytes. First, HepG2 cells were dispensed into 96-well microplates at 2.5 × 10 4 cells (100 μl) per well and fixed. Next, 25 μl of the same andrographolide as used in Test Example 1 was added to each well so that the final concentration was 6.3 μM, and further cultured for 44 hours. Thereafter, t-butyl hydroperoxide (t-BHP), which is a peroxide compound, was added so that the final concentration was 0 to 1 mM, and the cell viability after 3 hours was measured. The results are shown in FIG. The cell viability was calculated using the WST-1 staining method with the t-BHP non-added control as 100%.

図2より、アンドログラホリドの使用により、酸化ストレス抵抗性を高めることができることが確認された。   From FIG. 2, it was confirmed that the use of andrographolide can enhance oxidative stress resistance.

表2から明らかなように、薬剤未添加、抗酸化剤として汎用されているカテキンとアンドログラホリドを比較した結果、未添加及びカテキンに比べ、アンドログラホリドは優れたシワ・肌荒れ改善効果を示すことが明らかとなった。以上の結果より、アンドログラホリドはPAFアセチルハイドロラーゼの細胞の膜への移行性を高めることで酸化された膜を修復し、酸化ストレス抵抗性を高めることが実証された。   As is apparent from Table 2, as a result of comparing catechin and andrographolide, which are widely used as anti-oxidants with no drug added, andrographolide has an excellent wrinkle / roughness-improving effect compared with catechin not added and catechin. It became clear. From the above results, it was demonstrated that andrographolide repairs the oxidized membrane by increasing the migration of PAF acetylhydrolase to the cell membrane, and increases resistance to oxidative stress.
