- Nrf2 is a transcription factor having a basic leucine zipper motif that exists in mammals. Nrf2 is expressed in a wide range of organs and is usually present in the cytoplasm by binding to the Keap1 protein, but it is an electrophilic substance. It is transferred into the nucleus by stimulation of oxidative stress and forms a heterodimer with a small Maf protein to induce expression of genes related to detoxification and antioxidant. With this transcriptional activation, the Nrf2 complex binds to an antioxidant response element (ARE) that is commonly present in the promoter region of the target gene cluster. So far, analysis of Nrf2-deficient mice suggests that activation of Nrf2 contributes to suppression of carcinogenesis, liver injury, lung injury, inflammation and the like.

- shaft of FIG.1 and 2 shows the survival rate of a nematode
- a horizontal axis shows the breeding days (lifetime) after reaching an adult
- foot of a graph shows a standard deviation. 1 and 2 indicate the number of nematodes at the time of the test. The same applies to FIGS. 3 and 4 below.
- Example 5 comparative example 2: acetone adduct
- the acetone adduct produced in Production Example 2, sodium bicarbonate of the same weight, and sterilized water were mixed to obtain test sample concentrate 2.
- Test sample concentrate 2 was adjusted so that the content of the acetone adduct was 30 mM.
- Example 1 except that the addition amount of test sample concentrate 2 was adjusted so that the concentration of the acetone adduct in the medium solution was 0 mM (Comparative Example 2) and 5.0 mM (Example 5). By the same operation, a petri dish having media containing different concentrations of acetone adducts was produced. Thereafter, a life test was conducted in the same manner as in Example 1. The result is shown in FIG.
- the average lifetime tends to be extended by including the acetone adduct.
- IPQ trisodium salt The IPQ trisodium salt prepared in Production Example 3 and water were mixed to obtain a test sample concentrate 3. Test sample concentrate 3 was adjusted so that the content of IPQ trisodium salt was 30 mM. The test sample concentrate 3 was used by autoclave sterilization.
- Example 1 except that the amount of test sample concentrate 3 was adjusted so that the concentration of IPQ trisodium salt in the medium solution was 0 mM (Comparative Example 3) and 5.0 mM (Comparative Example 4).
- Petri dishes having culture media containing different concentrations of IPQ trisodium salt were prepared by the same operation as described above. Thereafter, a life test was conducted in the same manner as in Example 1. The result is shown in FIG. In FIG. 4, the data of Example 4 are also shown.
- Example 8 Stability of reduced PQQ
- Reduced PQQ was added to sterilized water to prepare a 30 mM dispersion. This was added so that it might become 5 mM in the said composition for evaluation, and the petri dish was produced. A storage test was conducted at 30 degrees for 3 days, and LC analysis and UV spectrum analysis were performed. The reduced form changes to PQQ under neutral conditions. Therefore, the reduction state can be confirmed by detecting PQQ by LC analysis, dissolving it with dimethyl sulfoxide, and measuring the UV spectrum. As a result of confirming the state of reduced PQQ in the agar medium in this way, 86% of all PQQs maintained the reduced state.
- Example 1-5 E. coli colonies in the petri dish used in Example 1-5 were taken out and extracted and analyzed in the same manner as the medium analysis. The test substance was also detected as a major component from E. coli used for the test.
- IPQ amino acids in peptone
- IPQ has a small effect of extending the life, and it can be seen that PQQ is an active ingredient. Further, it was found that IPQ that is easily generated by using an acetone adduct was not observed, and the stability was improved.
- Example 14 and Example 17 the life-extension effect by PQQ was not observed in the strains with reduced function of the bli-3 gene.
- the life span was extended by adding PQQ, and a phenotype that did not cause a life extension was rescued by PQQ.
- the bli-3 gene is a gene that is useful for realizing longevity. In other words, it can be said that PQQ activates dual oxidase.
- the nematode bli-3 gene corresponds to the mammalian DUOX1 gene and the DUOX2 gene.
- nsy-1 (ky400) and pmk-3 (ok169) mutants are strains in which the activities of ASK-1 / MAPKKKK and p38 / MAPK are reduced, respectively.
- PQQ activates the dual oxidase encoded by the upstream bli-3. Thereafter, ROS produced from the activated dual oxidase activates SKN-1 / NRF-2 via activation of the p38 MAPK cascade.
- ROS active oxygen
- the dual oxidase activated by PQQ enhances the biological defense response and contributes to the life extension.
- active oxygen ROS
- ROS active oxygen
- an antioxidant is effective for preventing aging of the living body.
- PQQ not as an antioxidant, surprisingly extends life by enhancing the action of active oxygen producing enzymes.
- the life extension agent and dual oxidase activator of the present invention have industrial applicability in applications such as foods, feeds, and pharmaceuticals.

〔寿命試験〕
〔線虫用培地の作製〕
ピロロキノリンキノンジナトリウムを水と水酸化ナトリウムとを混合し、pH6の試験サンプル濃縮液1を得た。
(シンクロナイズ(年齢の調整))
実験開始時の線虫個体の年齢を同期させるため、産卵させたあと親虫を取り除き、孵化させて一定時間の期間一様に育てた個体を使用した。具体的には、シャーレに5匹ずつ、adult(抱卵している個体)を選んで移し、20℃で2時間放置(産卵期間)し、親虫を取り除いた。その後、20℃で72時間放置し、1シャーレあたり10~20匹となったところで寿命試験を開始した。1シャーレあたり10~20匹という低密度で飼育することで、エサの不足や排泄物の蓄積に由来する影響を減少させた。
シャーレ内の個体を毎日新しいシャーレに移し替えた。スコアシートに日付、生存数、死亡数、行方不明数などの情報を記録した。保管時はシャーレにパラフィルムをまいた。自発的な行動がみられず、振動刺激や接触刺激を与えても全く反応がみられなかった場合を死亡と判断した。また、線虫がシャーレ外へ逃走したり、壁面で乾燥したり、培地の隙間から潜り込んだりするなどの理由で行方不明になることがしばしば起こるため、行方不明数を記録し、データからは除外した。また、ある種の変異体において頻出する自分の子供が体内で羽化して死亡する個体をBAG、脱腸などにより個体が死亡する個体を破裂と記録し、テータからは除外した。培地中のピロロキノリンキノンジナトリウム塩の濃度を変えて測定した結果を図1及び2に示す。
製造例2で作製したアセトン付加体と、同重量の炭酸水素ナトリウムと、滅菌水とを混合し、試験サンプル濃縮液2を得た。試験サンプル濃縮液2は、アセトン付加体の含有量が30mMになるように調整した。
製造例3で作製したIPQトリナトリウム塩と水とを混合し、試験サンプル濃縮液3を得た。試験サンプル濃縮液3は、IPQトリナトリウム塩の含有量が30mMになるように調整した。また、試験サンプル濃縮液3は、オートクレーブ滅菌により使用した。
寿命試験に使用したシャーレ中の還元型ピロロキノリンキノン、ピロロキノリンキノンのアセトン付加体、及びIPQトリナトリウム塩の安定性を液体クロマトグラフィー分析(LC分析)によって評価した。その結果を表1に示す。なお、液体クロマトグラフィー分析は、上記したものに従って行うことができる。
還元型PQQを滅菌水に加え、30mMの分散液を作製した。これを前記の評価用組成において5mMになるように添加してシャーレを作製した。30度で3日保存試験を行い、LC分析、およびUVスペクトル分析を行った。還元型は中性条件ではPQQに変化する。そのため、LC分析によりPQQを検出し、それをジメチルスルホキシドで溶解しUVスペクトルを測定することで還元状態を確認できる。このようにして寒天培地中の還元型PQQの状態を確認した結果、全PQQのうち86%が還元状態を維持していた。
線虫の変異体を使用することでPQQがどのように働いているかを知ることができる。実施例4で調製したPQQ5mMを含む培地を用いて、シャーレを複数作製した。作製したシャーレを用いて、表2に示す各変異体で上記実施例1と同様に寿命延長試験を行った。その結果を以下の表2にまとめる。相対的な効果としてPQQを添加しない場合を100として示す。なお、表2は成体に成長したのちの、5mMPQQにおける寿命延長を示す。
