  • Drug-induced myocardial damage is a so-called side effect of anticancer drugs, and is also considered a problem in cancer chemotherapy treatment.
  • Drug-induced myocardial injury is a disease whose basic condition is cardiomyopathy caused by damage to the myocardium caused by drugs, and patients who develop this disease may develop intractable heart failure and die.
  • Non-Patent Document 1 Non-Patent Document 1
  • Non-Patent Document 2 The development of drug-induced myocardial damage caused by anthracycline anticancer drugs including doxorubicin involves inhibition of topoisomerase 2 ⁇ activity expressed in cardiomyocytes, resulting in DNA damage, mitochondrial dysfunction, and increased production of reactive oxygen species. Guidance is considered to be important (Non-Patent Document 2).
  • Ferroptosis is a phenomenon in which various stimuli cause a decrease in antioxidant function such as a decrease in the amount of intracellular glutathione and glutathione peroxidase 4 (GPX4), and as a result of divalent iron-dependent reactions progressing, intracellular lipid peroxide becomes lethal.

Description

薬剤性心筋障害の治療剤又は予防剤Treatment or prevention agent for drug-induced myocardial damage
 本発明は、薬剤性心筋障害の治療剤又は予防剤に関する。 The present invention relates to a therapeutic or preventive agent for drug-induced myocardial damage.
 心筋症において薬剤性心筋障害はいわゆる抗がん剤の副作用であり、がん化学療法治療においても問題とされている。薬剤性心筋障害は、薬剤によって心筋の障害が引き起こされて心筋症を呈することを基本病態とする疾患であり、これを発症した患者は、難治性心不全を呈して死に至ることがある。 In cardiomyopathy, drug-induced myocardial damage is a so-called side effect of anticancer drugs, and is also considered a problem in cancer chemotherapy treatment. Drug-induced myocardial injury is a disease whose basic condition is cardiomyopathy caused by damage to the myocardium caused by drugs, and patients who develop this disease may develop intractable heart failure and die.
 これまでに、多数の薬剤が薬剤性心筋障害を引き起こすことが報告されている。特に、抗がん剤として広く使用されている代表的な薬剤であるドキソルビシン等のアントラサイクリン系薬剤は、投与後早期から心筋障害を引き起こすが、軽微な障害であっても慢性期に心筋リモデリングが進行し、不可逆かつ進行性の薬剤性心筋症を引き起こす場合がある(非特許文献1)。 To date, many drugs have been reported to cause drug-induced myocardial damage. In particular, anthracyclines such as doxorubicin, a typical drug widely used as an anticancer drug, cause myocardial damage early after administration, but even if the damage is minor, myocardial remodeling occurs in the chronic phase. may progress and cause irreversible and progressive drug-induced cardiomyopathy (Non-Patent Document 1).
 ドキソルビシンを含むアントラサイクリン系抗がん剤に起因する薬剤性心筋障害の発症には心筋細胞に発現するトポイソメラーゼ2β活性の阻害、これによって引き起こされるDNA障害、ミトコンドリア機能障害及び活性酸素種産生亢進等の誘導が重要だと考えられている(非特許文献2)。 The development of drug-induced myocardial damage caused by anthracycline anticancer drugs including doxorubicin involves inhibition of topoisomerase 2β activity expressed in cardiomyocytes, resulting in DNA damage, mitochondrial dysfunction, and increased production of reactive oxygen species. Guidance is considered to be important (Non-Patent Document 2).
 近年、様々な形態の制御性細胞死があることが判明してきており、2価鉄依存性の制御性細胞死の形態をとる新しい細胞死の一種として、フェロトーシス(Ferroptosis)が報告されている(非特許文献3)。フェロトーシスとは、種々の刺激により細胞内グルタチオン量やグルタチオンペルオキシダーゼ4(GPX4)の低下といった抗酸化機能の低下が生じ、2価鉄依存性の反応が進行することにより細胞内脂質ペルオキシドが致死的なレベルまで上昇し、細胞死が生じる反応のことである。 In recent years, it has become clear that there are various forms of regulated cell death, and ferroptosis has been reported as a new type of cell death that takes the form of divalent iron-dependent regulated cell death. (Non-patent document 3). Ferroptosis is a phenomenon in which various stimuli cause a decrease in antioxidant function such as a decrease in the amount of intracellular glutathione and glutathione peroxidase 4 (GPX4), and as a result of divalent iron-dependent reactions progressing, intracellular lipid peroxide becomes lethal. This is a reaction in which the amount of cells increases to a certain level, resulting in cell death.
 最近、ドキソルビシンに起因する薬剤性心筋障害にフェロトーシスの関与が報告されている。例えばドキソルビシンを投与したマウスでは心筋障害に加え、GPX4の低下や、過酸化脂質の増加が報告されている。さらに、GPX4を過剰発現したマウスでは心筋障害の改善や過酸化脂質の低下が報告され、薬剤性心筋症の治療にはフェロトーシス阻害が有用な方法だと考えられている(非特許文献4)。 Recently, the involvement of ferroptosis in drug-induced myocardial damage caused by doxorubicin has been reported. For example, mice administered doxorubicin have been reported to have myocardial damage, as well as a decrease in GPX4 and an increase in lipid peroxide. Furthermore, it has been reported that mice overexpressing GPX4 have improved myocardial damage and decreased lipid peroxide levels, and ferroptosis inhibition is considered to be a useful method for treating drug-induced cardiomyopathy (Non-Patent Document 4). .
 フェロトーシス阻害作用を示す化合物としては、Ferrostatin-1等のアニリン誘導体が知られている(非特許文献3、5)。また、テトラヒドロキノキサリン誘導体や3,4-ジヒドロ-2H-ベンゾ-[1,4]オキサジン誘導体もフェロトーシス阻害作用を有することが開示されている(特許文献1,2)。 Aniline derivatives such as Ferrostatin-1 are known as compounds that exhibit a ferroptosis inhibitory effect (Non-Patent Documents 3 and 5). Furthermore, it has been disclosed that tetrahydroquinoxaline derivatives and 3,4-dihydro-2H-benzo-[1,4]oxazine derivatives also have ferroptosis inhibiting effects (Patent Documents 1 and 2).
 フェロトーシス阻害作用の発現には、ラジカル捕捉作用が重要であることが報告されている(非特許文献6)。また、特許文献1に記載のテトラヒドロキノキサリン誘導体は、強力なラジカル捕捉作用を有すること、その結果としてフェロトーシス阻害作用を発現することが開示されている(非特許文献7、8)。 It has been reported that radical scavenging action is important for the expression of ferroptosis inhibitory action (Non-Patent Document 6). Furthermore, it has been disclosed that the tetrahydroquinoxaline derivative described in Patent Document 1 has a strong radical scavenging effect and, as a result, exhibits a ferroptosis inhibiting effect (Non-patent Documents 7 and 8).
 一方、特許文献3~7には、抗ウイルス作用、抗腫瘍作用、疼痛治療作用又は免疫応答の修飾作用を有するテトラヒドロキノリン誘導体が開示されている。 On the other hand, Patent Documents 3 to 7 disclose tetrahydroquinoline derivatives having antiviral action, antitumor action, pain treatment action, or immune response modification action.

 しかしながら、特許文献1~7及び非特許文献1~8には、テトラヒドロキノリン誘導体のフェロトーシス阻害作用及び薬剤性心筋障害の治療又は予防についての開示はなく、その可能性について示唆もされていない。また、薬剤性心筋障害の発症リスクは正確な予測には至っておらず、薬剤性心筋障害の予防・治療法の開発は社会的に強く求められているにも関わらず、有効な手段がない。 However, Patent Documents 1 to 7 and Non-Patent Documents 1 to 8 do not disclose the ferroptosis inhibiting effect of tetrahydroquinoline derivatives and the treatment or prevention of drug-induced myocardial damage, nor do they suggest the possibility thereof. Furthermore, the risk of developing drug-induced myocardial damage has not been accurately predicted, and although there is a strong social need to develop preventive and therapeutic methods for drug-induced myocardial damage, there is no effective method.
 そこで本発明は、フェロトーシス阻害作用を有し、薬剤性心筋症に対して治療又は予防効果を発揮する化合物を提供することを目的とする。 Therefore, an object of the present invention is to provide a compound that has a ferroptosis inhibiting effect and exhibits a therapeutic or preventive effect on drug-induced cardiomyopathy.
 本発明者らは、上記の課題を解決すべく鋭意研究を重ねた結果、新規なテトラヒドロキノリン骨格を有する化合物が、フェロトーシス阻害作用を有し、薬剤性心筋障害に対し著しい症状抑制効果を有することを見出し、本発明を完成するに至った。 As a result of intensive research aimed at solving the above problems, the present inventors found that a novel compound having a tetrahydroquinoline skeleton has a ferroptosis inhibitory effect and has a remarkable symptom-suppressing effect on drug-induced myocardial damage. This discovery led to the completion of the present invention.

 「フェロトーシス阻害」とは、フェロトーシス(2価鉄依存的に制御される細胞死)を阻害することを意味する。本発明のフェロトーシス阻害剤は、フェロトーシスを阻害することによって病態の改善又は症状の寛解が期待できる疾患、障害又は症候群に対して用いることができる。 "Ferrotosis inhibition" means inhibiting ferroptosis (cell death controlled in a divalent iron-dependent manner). The ferroptosis inhibitor of the present invention can be used for diseases, disorders, or syndromes in which improvement of pathological conditions or remission of symptoms can be expected by inhibiting ferroptosis.
 薬剤性心筋障害とはいわゆる抗がん剤の副作用であり、がん化学療法治療においても問題とされている。薬剤性心筋障害は、薬剤によって心筋の障害が引き起こされて心筋症を呈することを基本病態とする疾患であり、これを発症した患者は、難治性心不全を呈して死に至ることがある。特に、抗がん剤として広く使用されている代表的な薬剤であるドキソルビシン等のアントラサイクリン系薬剤は、投与後早期から心筋障害を引き起こすが、軽微な障害であっても慢性期に心筋リモデリングが進行し、不可逆かつ進行性の薬剤性心筋症を引き起こす場合がある。 Drug-induced myocardial damage is a so-called side effect of anticancer drugs, and is also considered a problem in cancer chemotherapy treatment. Drug-induced myocardial injury is a disease whose basic condition is cardiomyopathy caused by damage to the myocardium caused by drugs, and patients who develop this disease may develop intractable heart failure and die. In particular, anthracyclines such as doxorubicin, a typical drug widely used as an anticancer drug, cause myocardial damage early after administration, but even if the damage is minor, myocardial remodeling occurs in the chronic phase. may progress and cause irreversible and progressive drug-induced cardiomyopathy.
 なお、本発明のテトラヒドロキノリン誘導体(I)又はその薬理学的に許容される塩は、テトラヒドロキノリン誘導体(I)又はその薬理学的に許容される塩を有効成分として含有するフェロトーシス阻害剤である、薬剤性心筋障害の治療剤又は予防剤として使用することもできる。ここで、上記フェロトーシス阻害剤としては、テトラヒドロキノリン誘導体(I)又はその薬理学的に許容される塩や2-フェニル-1,2,3,4-テトラヒドロキノリン又はその薬理学的に許容される塩を用いることができる。 The tetrahydroquinoline derivative (I) or a pharmacologically acceptable salt thereof of the present invention is a ferroptosis inhibitor containing the tetrahydroquinoline derivative (I) or a pharmacologically acceptable salt thereof as an active ingredient. It can also be used as a therapeutic or preventive agent for certain drug-induced myocardial disorders.

 ところで、フェロトーシス阻害作用を示すには非特許文献6に記載の通りラジカル捕捉作用を有することが重要であることが報告されている。また、特許文献1及び非特許文献7にはテトラヒドロキノキサリン誘導体が強力なラジカル捕捉作用を有することが開示されている。一方、非特許文献7にはテトラヒドロキノリン誘導体はラジカル捕捉作用が極めて弱いことが報告されている。それにもかかわらず、本発明のテトラヒドロキノリン誘導体(I)又はその薬理学的に許容される塩は、フェロトーシス阻害作用を示すことから、薬剤性心筋障害を治療又は予防するための新たな医薬として用いることができる。 By the way, it has been reported that in order to exhibit a ferroptosis inhibiting effect, it is important to have a radical scavenging effect as described in Non-Patent Document 6. Further, Patent Document 1 and Non-Patent Document 7 disclose that tetrahydroquinoxaline derivatives have a strong radical scavenging effect. On the other hand, Non-Patent Document 7 reports that tetrahydroquinoline derivatives have an extremely weak radical scavenging effect. Nevertheless, the tetrahydroquinoline derivative (I) of the present invention or a pharmacologically acceptable salt thereof exhibits a ferroptosis inhibiting effect, and therefore can be used as a new pharmaceutical for treating or preventing drug-induced myocardial damage.

 テトラヒドロキノリン誘導体(I)又はその薬理学的に許容される塩のフェロトーシス阻害作用は、in vitro試験を用いて評価することができる。例えば、ヒト線維肉腫細胞(HT-1080細胞)等の株化細胞や初代培養細胞やiPS細胞等にフェロトーシス誘導剤であるErastin、RSL3、FIN56又はブチオニンスルフォキシミン等を処置することで生じる細胞死の抑制作用を指標に評価することができる。 The ferroptosis inhibitory effect of the tetrahydroquinoline derivative (I) or a pharmacologically acceptable salt thereof can be evaluated using an in vitro test. For example, by treating established cell lines such as human fibrosarcoma cells (HT-1080 cells), primary cultured cells, iPS cells, etc. with ferroptosis inducers such as Erastin, RSL3, FIN56, or buthionine sulfoximine. The inhibitory effect on cell death that occurs can be used as an index for evaluation.
 被験化合物のラジカル捕捉作用はin vitro試験を用いて評価することができる。例えば、安定ラジカルである1,1-Diphenyl-2-picrylhydrazyl(DPPH)を用いた方法(Antioxidants、2019年、第258巻)で評価することができる。 The radical scavenging effect of a test compound can be evaluated using an in vitro test.

Examples of pathological models include the doxorubicin-induced myocardial injury model (Journal of Clinical Investigation Insight, 2020, Vol. 5, e132747) as a drug-induced myocardial injury model. The doxorubicin-induced myocardial injury model is an animal model in which myocardial damage such as decreased heart weight, decreased left ventricular diameter shortening, and decreased ejection fraction is induced by administering the anticancer drug doxorubicin to experimental animals. be. The above-mentioned pathological model is widely used to examine the efficacy of therapeutic or preventive agents for drug-induced myocardial damage due to the similarity of its symptoms and pathological findings to humans. The effectiveness in treating or preventing drug-induced myocardial damage can be evaluated using the above-mentioned doxorubicin-induced myocardial damage model using, for example, body weight, heart weight, left ventricular diameter shortening rate, and ejection fraction as indicators. .

 テトラヒドロキノリン誘導体(I)又はその薬理学的に許容される塩のフェロトーシス阻害作用を、ヒト線維肉腫細胞(HT-1080細胞)を用いて、フェロトーシス誘導剤であるErastin処置により生じる細胞死に対する阻害作用を指標として評価した。
(Example 173) In vitro ferroptosis inhibition effect:
The ferroptosis-inhibiting effect of the tetrahydroquinoline derivative (I) or its pharmacologically acceptable salt was demonstrated using human fibrosarcoma cells (HT-1080 cells) against cell death caused by treatment with Erastin, a ferroptosis-inducing agent. The inhibitory effect was evaluated as an index.
 HT-1080細胞(ATCC)は、DMEM/F12(サーモフィッシャーサイエンス社)に牛胎児血清(サーモフィッシャーサイエンス社)を10%濃度、ペニシリンストレプトマイシン溶液(ナカライテスク社)を1%濃度で混合したもの(以下、溶媒)で培養した。96ウェルプレート(コーニング社)に各ウェル5×10個となるように細胞を播種し一晩培養した。 HT-1080 cells (ATCC) were obtained by mixing DMEM/F12 (Thermo Fisher Sciences) with fetal bovine serum (Thermo Fisher Sciences) at a concentration of 10% and penicillin-streptomycin solution (Nacalai Tesque) at a concentration of 1% ( The cells were cultured in a solvent (hereinafter referred to as "solvent"). Cells were seeded in a 96-well plate (Corning) at 5 x 10 cells per well and cultured overnight.
 被験化合物を、DMSOに溶解した後、DMSOの最終濃度が1%となるように溶媒に希釈して使用した。播種翌日に、最終評価濃度25、30又は50μmol/Lとなるように溶媒に希釈した被験化合物を添加した。添加から30分後に、最終濃度3μmol/Lとなるように溶媒に希釈したErastin(ケイマン社)を添加した。被験化合物添加+Erastin添加のウェルを「被験化合物」とし、被験化合物非添加+Erastin非添加のウェルを「バックグラウンド」とし、被験化合物非添加+Erastin添加のウェルを「コントロール」とした。Erastin添加から24時間後、Cell counting kit-8(同仁化学研究所社)を各ウェル5μLずつ添加し、4時間インキュベートした後、各ウェルの吸光度450nmの値を測定した(N=2)。各ウェルの吸光度450nmの値の平均値を算出した後、被験化合物によるフェロトーシスの阻害率(以下、フェロトーシス阻害率)(%)を下式1から算出した。 The test compound was dissolved in DMSO and then diluted with a solvent to give a final DMSO concentration of 1% before use. On the day after seeding, a test compound diluted in a solvent to a final evaluation concentration of 25, 30, or 50 μmol/L was added. Thirty minutes after the addition, Erastin (Cayman) diluted in a solvent to a final concentration of 3 μmol/L was added. Wells to which the test compound was added and Erastin were added were defined as "test compound," wells to which no test compound and Erastin were added were defined as "background," and wells to which no test compound and Erastin were added were defined as "controls." 24 hours after the addition of Erastin, 5 μL of Cell counting kit-8 (Dojindo Laboratories) was added to each well, and after incubation for 4 hours, the absorbance at 450 nm of each well was measured (N=2). After calculating the average value of the absorbance at 450 nm of each well, the inhibition rate of ferroptosis (hereinafter referred to as ferroptosis inhibition rate) (%) by the test compound was calculated from the following formula 1.
 フェロトーシス阻害率(%)=[1-{(被験化合物添加時吸光度450nmの値の平均値)-(バックグラウンドの吸光度450nmの値の平均値)}/{(コントロールの吸光度450nmの値の平均値)-(バックグラウンドの吸光度450nmの値の平均値)}]×100・・・式1 Ferroptosis inhibition rate (%) = [1-{(average value of absorbance at 450 nm when test compound is added)-(average value of background absorbance at 450 nm)}/{(average value of absorbance at 450 nm of control) value) - (average value of background absorbance at 450 nm)}]×100...Formula 1

 テトラヒドロキノキサリン誘導体である比較例1の化合物、及び、テトラヒドロキノリン誘導体(I)又はその薬理学的に許容される塩のラジカル捕捉作用を、DPPH法を用いて評価した。DPPH法は抗酸化能測定キット(同仁化学研究所)を用いて実施した。
(Example 174) In vitro radical scavenging effect:
The radical scavenging effects of the compound of Comparative Example 1, which is a tetrahydroquinoxaline derivative, and the tetrahydroquinoline derivative (I) or a pharmacologically acceptable salt thereof were evaluated using the DPPH method. The DPPH method was performed using an antioxidant capacity measurement kit (Dojindo Laboratories).
 被験化合物を、DMSOに溶解した後、DMSOの最終濃度10%となるように、キット付属のアッセイバッファー及びDPPH溶液と全量200μLとして反応させた。ラジカル捕捉剤であるFerrostatin-1を100μmol/L添加したウェルを「コントロール」とし、被験化合物非添加のウェルを「バックグラウンド」とした。被験化合物は最高濃度100μmol/Lから公比3で段階希釈し添加し、室温で反応させた(1.2、3.7、11.1、33.3、100μmol/L)。反応から30分後に吸光度517nmの値を測定し、平均値を算出した(N=2)。被験化合物によるラジカル捕捉作用(以下、ラジカル捕捉率)(%)を下式2から算出した。ラジカル捕捉率から被験化合物のEC50値を算出した。 After the test compound was dissolved in DMSO, it was reacted with the assay buffer and DPPH solution provided in the kit in a total volume of 200 μL so that the final concentration of DMSO was 10%. Wells to which 100 μmol/L of Ferrostatin-1, a radical scavenger, was added were defined as "controls", and wells to which no test compound was added were defined as "background". The test compound was added after being serially diluted at a common ratio of 3 from the highest concentration of 100 μmol/L, and reacted at room temperature (1.2, 3.7, 11.1, 33.3, 100 μmol/L). 30 minutes after the reaction, the absorbance at 517 nm was measured and the average value was calculated (N=2). The radical scavenging effect (hereinafter referred to as radical scavenging rate) (%) by the test compound was calculated from the following formula 2. The EC 50 value of the test compound was calculated from the radical scavenging rate.
 捕捉ラジカル捕捉率(%)=[1-{(被験化合物添加時の吸光度517nmの値の平均値)-(バックグラウンドの吸光度517nmの値の平均値)}/{(コントロールの吸光度517nmの値の平均値)-(バックグラウンドの吸光度517nmの値の平均値)}]×100・・・式2 Captured radical capture rate (%) = [1-{(average value of absorbance at 517 nm when test compound is added)-(average value of background absorbance at 517 nm)}/{(average value of absorbance at 517 nm of control) Average value) - (average value of background absorbance at 517 nm)}]×100...Formula 2
 被験化合物処置によるラジカル捕捉率(%)を表3-1及び表3-2に示す。EC50>100μmol/Lを示す化合物はラジカル捕捉作用未検出(N.D.)と表記した。 The radical scavenging rate (%) by test compound treatment is shown in Table 3-1 and Table 3-2. Compounds exhibiting EC 50 >100 μmol/L were designated as having no radical scavenging activity detected (N.D.).
 この結果から、テトラヒドロキノキサリン誘導体である比較例1の化合物はラジカル捕捉作用を示した。一方、本発明のテトラヒドロキノリン誘導体(I)又はその薬理学的に許容される塩はラジカル捕捉作用を有さないことが明らかとなった。 From this result, the compound of Comparative Example 1, which is a tetrahydroquinoxaline derivative, showed a radical scavenging effect. On the other hand, it has been revealed that the tetrahydroquinoline derivative (I) or a pharmacologically acceptable salt thereof of the present invention does not have a radical scavenging effect.
