Definitions
- the present invention relates to agents used for activating or enhancing the expression of sirtuins or klotho, increasing NAD + , and suppressing senescent cells.
- Sirtuin and Klotho are known as molecules whose life span is extended by high expression in nematodes, flies, mammals, etc., and whose life span is shortened by deletion.
- Sirtuins are NAD + -dependent deacetylases whose genes are widely conserved from bacteria to eukaryotes. Deletion of Sir2, a sirtuin homolog of yeast and nematodes, shortens lifespan, and overexpression extends lifespan.
- SIRT1-7 sirtuins in mammals, among which SIRT1, which is most similar in structure and function to yeast Sir2, is involved in gene expression associated with aging, intracellular metabolism, energy consumption, inflammation and stress response.
- Non-Patent Document 1 Possibility of involvement in regulation of a wide range of cell functions such as pathways has been clarified (Non-Patent Document 1).
- sirtuins may be related to specific diseases.
- Non-Patent Document 2 shows that cognitive functions including immediate memory, classical conditioning, and spatial learning are impaired in SIRT1 knockout mice.
- overexpression of SIRT1 was found to exhibit ordered synaptic plasticity and memory. From this, it has been clarified that SIRT1 acts on normal learning, memory, and synaptic plasticity.
- Nicotinamide mononucleotide functions in vivo as a coenzyme for dehydrogenase and as a substrate for sirtuins. Also, increasing NAD + levels are known to increase the activity of sirtuins. NAD synthesis is controlled by nicotinamide phosphoribosyltransferase (NAMPT). Since the function of NAMPT declines with age, it is known that the amount of NAD + decreases and the activity of sirtuins declines.
- Non-Patent Document 3 discloses that administration of nicotinamide riboside, which is a precursor of NAD + , suppresses senescent cells in the brain.
- Klotho maintains phosphorus homeostasis as a receptor for fibroblast growth factor 23.
- CKD chronic kidney disease
- Cellular senescence is caused by excessive DNA damage caused by the accumulation of DNA replication errors accompanying cell division, oxidative stress, radiation, activation of oncogenes, etc., resulting in the activation of the p16/RB and p53/p21 pathways. It is a phenomenon in which irreversible cell cycle arrest occurs due to the induction of inhibitors of cyclin inhibitory kinases.
- Cells undergoing cellular senescence (senescent cells) accumulate in tissues due to accelerated cell senescence and reduced ability to eliminate mitochondria and immune functions associated with aging.
- Senescent cells accumulated in tissues secrete inflammatory cytokines, proteases, and the like called senescence-related secretory factors, which damage surrounding tissues and promote aging of tissues and living organisms.
- Non-Patent Document 5 removal of senescent cells has been suggested to prevent or delay tissue dysfunction and suppress aging.
- Non-Patent Document 6 it has been clarified that an increase in senescent cells is involved in renal damage.

Abstract
Description
また、近年、サーチュインは特定の疾患との関係の可能性も明らかにされている。例えば、非特許文献2にはSIRT1のノックアウトマウスでは即時記憶、古典的条件付け及び空間学習を含む認知機能が低下した。逆に、SIRT1の過剰発現は規則正しいシナプス可塑性と記憶を示すことが認められた。このことから、SIRT1が正常な学習、記憶、シナプス可塑性に作用することが明らかにされている。

また、S-1-プロペニルシステイン又はその塩は、アリウム属植物を種々の方法で加工することにより得ることができる。例えば、加熱処理したアリウム属植物に、Bacillus subtilis由来のプロテアーゼ又はラクターゼを含む酵素を作用させS-1-プロペニルシステインを得る方法(特許第6105871号公報)、アリウム属の植物の搾汁又は抽出物にガンマグルタミルトランスペプチダーゼ又はグルタミナーゼ活性を有する酵素を共存させS-1-プロペニルシステインを得る方法(特開2015-144571号公報)、ニンニクに酵母を接種し発酵させS-1-プロペニルシステインを得る方法(韓国特許第2010-072874-5号)、アリウム属植物をエタノール水溶液中で1ヵ月以上熟成し、S-1-プロペニルシステインを得る方法(国際公開第2016/088892号、Molecules. 2017;22:570.)等が挙げられる。
ここで、陽イオン交換樹脂を用いた吸着・分離は、陽イオン交換樹脂(例えば、アンバーライト(ダウ・ケミカル社)、DOWEX(ダウ・ケミカル社製)、DIAION(三菱化学製)等)に吸着させ、0.1~3Nのアンモニア水で溶出させる方法が挙げられる。
順相クロマトグラフィーとしては、例えばシリカゲルカラムを用いて、クロロフォルム/メタノール/水混合物等で溶出させる方法が挙げられる。
逆相クロマトグラフィーとしては、例えばオクタデシルシリルカラムを用いて、0.01~3%ギ酸水溶液等で溶出させる方法が挙げられる。
上記工程1)及び2)によって得られるS-1-プロペニルシステインは、トランス体の割合が、トランス体とシス体の合計を100%とした場合に、大凡70~90%である。
また、後記試験例に示すように、S-1-プロペニルシステイン又はその塩は、老化細胞のマーカーであるp16及びp21を腎臓で、p53を海馬で発現した細胞を抑制した。よって、S-1-プロペニルシステイン、その塩又はこれらを含有する組成物は老化細胞抑制剤となり得る。
サーチュイン及びクロトーの活性化又は発現増強、老化細胞抑制、及びNAD+増加は、互いに共通する機構を有するという技術常識を考慮すると、S-1-プロペニルシステイン、その塩又はこれらを含有する組成物は、腎臓及び脳において作用させるための、サーチュイン又はクロトー活性化又は発現増強剤、NAD+増加剤、又は老化細胞抑制剤として使用し得る。

SIRT1又はクロトーの機能低下や細胞老化の亢進は、既に述べたように、腎障害、認知/記憶障害等の症状や疾患に関わっているとされている(非特許文献2、4、6)。したがって、本発明のサーチュイン又はクロトーの活性化又は発現増強剤及び老化細胞抑制剤は、腎障害、認知/記憶障害(短期及び長期を含む。)等の症状若しくは疾患の予防、治療又は改善のために用いられてよい。
「クロトー」とは、クロトータンパク質及びそのホモログを意味する。ヒトのクロトーには、α、β、γが知られているが、本発明においてはα-クロトーが好ましい。
「サーチュイン又はクロトー発現増強」とは、サーチュイン又はクロトー遺伝子の転写産物及び/又はサーチュイン又はクロトータンパク質が増加することであって、例えば、遺伝子の転写及び/又は翻訳の活性化、転写産物及び/又はタンパク質の安定性の向上、転写産物及び/又はタンンパク質分解の阻害等、が包含される。
p16、p21及びp53遺伝子は、細胞老化を引き起こすDNA損傷の分子マーカーとして知られているが、本発明の老化細胞抑制剤は、細胞老化を促進するミトコンドリアの機能不全やDNA損傷を抑制するものがより好ましい。また、免疫機能を高めることにより老化細胞をより効果的に抑制することができる。
ただし、当該医薬の剤形は、特に限定されず、非経口に適した剤形、例えば、静脈内(注射、カテーテル)、経粘膜(液剤又は軟膏)、頭蓋内投与(カテーテル)に適した剤形であってもよい。
