Definitions
- the present invention relates to a novel pharmaceutical composition for preventing or inhibiting acute kidney injury, comprising an angiotensin type 2 receptor (hereinafter referred to as AT 2 receptor) agonist or a pharmacologically acceptable salt thereof as an active ingredient. .
- AT 2 receptor angiotensin type 2 receptor
- the present invention also relates to a novel method for preventing or suppressing acute kidney injury.
- Renal failure refers to a condition in which renal function, mainly the excretion mechanism of normal kidneys, is impaired, and acute renal failure (ARF) and chronic kidney are caused by differences in the rate of progression of the decline in function. It is roughly divided into chronic renal failure (CRF).
- Chronic renal failure is a condition in which renal function gradually decreases over a long period due to causes such as hypertension and diabetes. When chronic renal failure occurs, recovery of renal function cannot be expected. At present, there is no effective treatment for chronic renal failure. Therefore, the main treatment is to delay the progression and prevent complications. As chronic renal failure progresses and transitions to end-stage renal failure, artificial dialysis or kidney transplantation is required.
- acute renal failure is a pathological condition in which renal function declines rapidly in a short period of time, resulting in hypernitremia, electrolyte abnormalities, uremia symptoms, etc. Dialysis therapy is introduced because it is at risk. Unlike chronic renal failure, acute renal failure can be expected to restore renal function by eliminating its cause, and early detection is important to prevent aggravation.
- Acute kidney injury is caused by various factors, and in particular, damage to tubular epithelial cells by administration of platinum antitumor agents (cisplatin, etc.) used as a central drug in many cancer chemotherapy. Occurs as a side effect such as acute kidney injury.
- platinum antitumor agents cisplatin, etc.
- cisplatin increases renal damage in a dose-dependent manner, the usage and dose of cisplatin are limited when renal damage occurs. Therefore, in clinical practice, in order to prevent or suppress the development of acute kidney injury, a large amount of physiological saline is administered or infused before and after cisplatin administration. It is difficult to prevent or suppress.
- angiotensinogen is converted into angiotensin I through renin, which is converted into angiotensin II (Ang II) having a strong and diverse physiological action by a converting enzyme such as angiotensin converting enzyme (ACE).
- a converting enzyme such as angiotensin converting enzyme (ACE).
- angiotensin type 1 receptor (hereinafter referred to as AT 1 receptor), and AT 2 receptors have been identified. It has been understood that the actions of Ang II such as pressorization and vasoconstriction, which are well known from the past, are mainly mediated by the classic AT 1 receptor. On the other hand, the AT 2 receptor functions in many cells / tissues by antagonizing the AT 1 receptor, and mainly develops pathological conditions such as antihypertensive, cell growth suppression, hypertrophy suppression, apoptosis promotion, and extracellular matrix production inhibition. In recent years, it has been elucidated that it works in the direction of stopping progress.
- AT 2 receptors are expressed in a wide range and high level prenatal, its expression level decreases after birth rapidly.
- pathological conditions such as vascular disorders and cardiovascular remodeling after myocardial infarction, it has become known that tissue-specific re-expression, and the AT 2 receptor involved in the prevention of onset and progression of various diseases The importance is drawing attention.
- Non-patent Document 2 A general pharmacological action predicted by activating the AT 2 receptor has been reported in a paper by de Gasparo et al. (Non-patent Document 2), and as a pharmaceutical use of an AT 2 receptor agonist for various diseases. A therapeutic or preventive effect is expected.
- the target diseases include many disease groups involving the renin-angiotensin-aldosterone system (hereinafter referred to as RAAS), such as metabolic / circulatory diseases, cerebral infarction, kidney disease, heart disease, hypertension, diabetes , Metabolic syndrome and the like.
- RAAS renin-angiotensin-aldosterone system
- Non-patent Documents 3 and 4 Patent Documents 1 to 9
- Each of these non-patent documents or compounds described in patent documents is characterized by a combination of a bisaryl structure and a sulfonamide group.
- Non-patent document 5 It has been described that even when LPS, which is an endotoxin, is allowed to act on human kidney cells, the concentration of TNF- ⁇ and IL-6 is reduced by the action of C21 (Non-patent Document 6). Further, in a mouse chronic renal failure model, since it exacerbates the renal damage by a deficiency of AT 2 receptors, it has been suggested that AT 2 receptor activation is useful in the treatment of chronic renal failure (Non Patent Document 7). However, these documents do not describe any relationship between the AT 2 receptor and acute kidney injury.
- malonic acid sulfonamide derivatives are also known as AT 2 receptor agonists and are described to be used for the treatment or prevention of renal diseases and the like (Patent Document 10), but prevention or suppression of acute kidney injury. Is not disclosed.

Abstract
Description
慢性腎不全は、高血圧や糖尿病等の原因により、長期間かけて徐々に腎機能が低下する病態である。慢性腎不全になると腎機能の回復は期待できず、現時点では慢性腎不全の有効な治療法はないため、その進行を遅らせ、合併症を予防する治療が主となる。慢性腎不全が進行し末期腎不全に移行すると、人工透析または腎臓移植が必要となる。
これに対し、急性腎不全は、短期間のうちに急激に腎機能が低下することによって、高窒素血症、電解質異常、尿毒症症状などが認められる病態であり、重篤な場合は生命の危険にさらされることから透析療法が導入される。急性腎不全は、慢性腎不全と異なり、その原因を除去することにより腎機能の回復を期待することができ、重症化を防ぐためには早期発見が重要となる。
さらに、マロン酸スルホンアミド誘導体は除草剤として知られているが(特許文献11)、無置換マロン酸スルホンアミド誘導体であり、マロン酸構造の2位に置換基を有するマロン酸スルホンアミド誘導体のAT2受容体アゴニストに関連する言及はない。

化合物C:(2S)-2-[4-(ベンゾイルアミノ)ベンジル]-N,N-ジエチル-N’-(2-ナフチルスルホニル)マロンアミド
8~9週齢の雄性C57BL/6マウス(n=7~14)にシスプラチン(CDDP) 15 mg/kg(病態群)またはリン酸緩衝生理食塩水(PBS、コントロール群)を15 mL/kgの容量で腹腔内投与した。化合物A又は化合物Cは30mg/kg/日の用量となるように、また化合物Bは45mg/kg/日の用量となるように、それぞれ調整された0.5%カルボキシメチルセルロース(CMC)水溶液(0.2mg/mL)を実験開始3日前から経口摂取させ、実験を行い、化合物A~Cの対照群には同容量の0.5% CMC水溶液を投与した。CDDP投与72時間後、セボフルラン麻酔下で腹部を切開し、シリンジを用いて腹部大静脈より全採血を行った。血液は遠心分離し、上清(血清)を採取した。血漿は-20~-80℃で保存した。なお、解剖直前にマウスより随時尿を採取した。
測定キットを使用して、血清尿素窒素(BUN)、血清クレアチニン(Cr),尿中アルブミン(Alb)および尿中Crを測定し、尿中Alb/Cr比を算出した。その結果を図1および図2に示す。
図1および図2から、シスプラチン(CDDP)投与により急性腎障害が発症したが、化合物A~Cは、CDDPによる急性腎障害を有意に抑制したことがわかる。
8~12週齢の雄性AT2受容体欠損マウス(n=3又は5~7)にシスプラチン(CDDP) 15 mg/kg(病態群)またはリン酸緩衝生理食塩水(PBS、コントロール群)を30 mL/kgの容量で腹腔内投与した。
化合物Cを30mg/kg/日の用量となるように調整された0.5%カルボキシメチルセルロース(CMC)水溶液(0.2mg/mL)を実験開始3日前から経口摂取させ、実験を行った。コントロール群には同容量の0.5% CMC水溶液を投与した。
CDDP投与72時間後、セボフルラン麻酔下で腹部を切開し、シリンジを用いて腹部大静脈より全採血を行った。血液は遠心分離し、上清(血清)を採取した。血清は-20~-80℃で保存した。なお、解剖直前にマウスより随時尿を採取した。
測定キットを使用して、尿中アルブミン(Alb)および尿中Crを測定し、これより尿中Alb/Cr比を算出すると共に、血清尿素窒素(BUN)を測定した。その結果を図3(尿中Alb/Cr比)および図4(BUN)に示す。
図3および図4から、AT2受容体欠損マウスでは、シスプラチン(CDDP)投与により急性腎障害が発症し、化合物Cを投与しても、CDDPによる急性腎障害を抑制することはできなかった。
