Description

本発明は、生体内でオートファジーを活性化できるオートファジー活性化剤に関する。 The present invention relates to an autophagy activator capable of activating autophagy in vivo.

オートファジーとは、細胞質の一部が隔離膜によって取り囲まれてオートファゴソームとよばれる膜構造を形成し、このオートファゴソームがリソソームと融合してオートリソソームとなって、老廃物や不要な蛋白質等を分解する細胞内分解機構である。近年、オートファジーが、生体において生理学的又は病理学的機能に重要な役割を担っており、オートファジー活性の低下が一因となっている疾患や症状が多数報告されている。このような疾患や症状としては、例えば、神経変性疾患、感染症、炎症性疾患、免疫疾患、腎疾患、呼吸器疾患、眼疾患、筋疾患、ミトコンドリア病、生活習慣病、皮膚老化、その他の各種疾患又は症状等がある。 In autophagy, a part of the cytoplasm is surrounded by an isolation membrane to form a membrane structure called autophagosome, and this autophagosome fuses with lysosome to become autophagosome, which produces waste products and unnecessary proteins. It is an intracellular degradation mechanism that degrades. In recent years, autophagy plays an important role in physiological or pathological functions in the living body, and many diseases and symptoms contributed by a decrease in autophagy activity have been reported. Such diseases and symptoms include, for example, neurodegenerative diseases, infectious diseases, inflammatory diseases, immune diseases, renal diseases, respiratory diseases, eye diseases, muscle diseases, mitochondrial diseases, lifestyle diseases, skin aging, and others. There are various diseases or symptoms.

そこで、従来、オートファジー活性の低下が一因となっている疾患や症状の予防又は治療のために、オートファジーを活性化する有効成分を配合した医薬や食品が種々開発されている。例えば、特許文献1には、メマンチン、クレマスチン及びそれらの塩をオートファジー誘導剤として使用できることが報告されている。特許文献2には、特定のピロロキノリンキノンをオートファジー誘導剤として使用できることが報告されている。特許文献3には、環状グルコオリゴ糖をオートファジー誘導剤として使用できることが報告されている。特許文献4には、梅肉エキスの疎水性有機溶媒抽出物又は梅肉エキスの中和処理物は、オートファジー誘導用飲食品として使用できることが開示されている。しかしながら、製剤処方の多様化、オートファジー活性化作用の更なる向上等に対応するために、オートファジーを活性化させる新たな有効成分の開発が望まれている。 Therefore, conventionally, various medicines and foods containing an active ingredient that activates autophagy have been developed for the prevention or treatment of diseases and symptoms that are caused by a decrease in autophagy activity. For example, Patent Document 1 reports that memantine, clemastine and salts thereof can be used as autophagy inducers. Patent Document 2 reports that a specific pyrroloquinoline quinone can be used as an autophagy inducer. Patent Document 3 reports that cyclic glucooligosaccharides can be used as autophagy inducers. Patent Document 4 discloses that the hydrophobic organic solvent extract of ume meat extract or the neutralized product of ume meat extract can be used as a food or drink for inducing autophagy. However, in order to cope with the diversification of pharmaceutical formulations and the further improvement of the autophagy activating action, it is desired to develop a new active ingredient that activates autophagy.

試験例1:オートファジー活性の測定
表1に示す成分について、オートファジー活性化効果を測定した。具体的には、先ず、NHEK細胞(正常ヒト新生児表皮角化細胞、クラボウ株式会社)をHuMedia-KG2培地(クラボウ株式会社)に懸濁させた液を、5×103cells/25μL/wellとなるように384ウェルプレートに播種して、37℃で終夜培養した。次いで、培地を除去後、表1に示す成分を含むHuMedia-KG2培地(以下、試験液)を各ウェルに25μL添加して、37℃で18時間インキュベートした。その後、各ウェルの上清を除去し、PBSで1回洗浄した後に、CYTO−ID(登録商標)オートファジー検出キット(Enzo Life Science,Inc)を用いて、オートファジー小胞を特異的に緑色に染色した。また、核をDAPIで青色に核染色した。また、ポジティブコントロールとして、前記試験液に代えて、ラパマイシンを0.457μg/mL含むHuMedia-KG2培地を使用して前記と同条件で操作を行った。更に、ネガティブコントロールとして、前記試験液に代えて、HuMedia-KG2培地(添加成分なし)を使用して前記と同条件で操作を行った。
Test Example 1: Measurement of autophagy activity The autophagy activation effect was measured for the components shown in Table 1. Specifically, first, a solution in which NHEK cells (normal human neonatal epidermal keratinocytes, Kurabou Co., Ltd.) was suspended in HuMedia-KG2 medium (Kurabou Co., Ltd.) was subjected to 5 × 10 3 cells / 25 μL / well. The seeds were sown in 384-well plates so as to be, and cultured at 37 ° C. overnight. Then, after removing the medium, 25 μL of HuMedia-KG2 medium (hereinafter, test solution) containing the components shown in Table 1 was added to each well, and the mixture was incubated at 37 ° C. for 18 hours. Then, the supernatant of each well is removed, washed once with PBS, and then the autophagy vesicles are specifically greened using the CYTO-ID® autophagy detection kit (Enzo Life Science, Inc). Was stained. In addition, the nuclei were stained blue with DAPI. Further, as a positive control, the operation was carried out under the same conditions as described above using HuMedia-KG2 medium containing 0.457 μg / mL of rapamycin instead of the test solution. Further, as a negative control, HuMedia-KG2 medium (without additional components) was used instead of the test solution, and the operation was carried out under the same conditions as described above.

次いで、各ウェルの中心部分を蛍光顕微鏡で観察し、ImageJを用いて画像解析を行い、緑色(オートファジー小胞)の蛍光強度と青色(核)の蛍光強度をそれぞれ求めた。細胞数を標準化するために、緑色(オートファジー小胞)の蛍光強度を青色(核)の蛍光強度で除して、オートファジー活性値を求めた。ポジティブコントロールのオートファジー活性値を1、ネガティブコントロールのオートファジー活性値を0として、各試験液のオートファジー活性値の相対値を算出した。 Next, the central portion of each well was observed with a fluorescence microscope, and image analysis was performed using ImageJ to determine the fluorescence intensity of green (autophagy vesicles) and blue (nucleus), respectively. In order to standardize the number of cells, the fluorescence intensity of green (autophagy vesicles) was divided by the fluorescence intensity of blue (nucleus) to obtain the autophagy activity value. The relative value of the autophagy activity value of each test solution was calculated by setting the autophagy activity value of the positive control to 1 and the autophagy activity value of the negative control to 0.

結果を表1に示す。この結果、セージ抽出物、ウイキョウ抽出物、ソウハクヒ抽出物、チョウジ抽出物、ゲンチアナ抽出物、シャクヤク抽出物、及び緑茶抽出物は、オートファジー活性値の相対値が1を超えており、ラパマイシンを凌ぐ優れたオートファジー活性化作用があることが明らかとなった。 The results are shown in Table 1. As a result, the sage extract, uikyo extract, sohakuhi extract, chouji extract, gentiana extract, sakuyaku extract, and green tea extract have an autophagy activity value of more than 1 and surpass rapamycin. It was revealed that it has an excellent autophagy activating effect.
