Description

【0001】
【発明の属する技術分野】
本発明は、優れたPARP阻害作用を有する新規4−アリール−5−ヒドロキシイソキノリン誘導体とその付加塩およびその製造方法に関する。
【0002】
【発明の背景】
ポリ(ADP−リボース)合成酵素(poly(ADP−ribose)polymerase;以下、「PARP」と略す)は、核内DNA機能調節タンパク質であり、DNAの損傷を認識することで活性化を受け、細胞内必須構成要素であるNAD(nicotinamide adenine dinucleotide)を酵素基質として、ポリ(ADP−リボース)をDNA−ポリメラーゼ等のアクセプタータンパク質に逐次結合させる酵素である。従って、PARPの過剰な活性化は、電子伝達系に必須なNADの枯渇に基づく細胞内エネルギー生産能の低下を惹起し、細胞死を招くと考えられている(C. Szabo, Free Radic. Biol. Med., 21, 855(1996))。また、PARPがインターロイキン−1β変換酵素様プロテアーゼファミリーの一つであるカスパーゼ−3の基質となって限定分解されることから、アポトーシス関連酵素としても注目を集めている。
【0003】
更に、PARP−ノックアウトマウスを用いた実験で、このノックアウトマウスの脳より採取された培養神経細胞が、一酸化窒素およびNMDA(N−methyl−D−aspartate)等の興奮性アミノ酸による障害に対して抵抗性を示すこと、更にこのノックアウトマウスは脳虚血により引き起こされる脳梗塞巣を約80%以上抑制する驚異的な保護効果を示すことが報告された(M.J.L. Eliasson et al., Nature Med.,3, 1089(1997))。これらのことからPARP阻害剤は、脳梗塞や神経変性疾患(アルツハイマー病、ハンチントン舞踏病、パーキンソン病等)に有効であると考えられている。これら以外にも、糖尿病、心筋梗塞や急性腎不全等の虚血あるいは虚血−再潅流による疾患、敗血症性ショック等の循環器系疾患、慢性関節リュウマチ、多発性硬化症といった炎症性疾患にも有効であるとの報告がある(C. Szabo et al., Trend Pharmacol Sci., 19, 287(1998))。またPARP阻害剤は、HIVを含む抗レトロウイルス剤(G. A. Cole et al., Biochem. Biophys. Res. Commun., 180, 504(1991))や抗癌療法の増感剤(C. Arundel−Suto, et al., Radiat. Res., 126, 367(1991);S. Boulton et al., Br. J. Cancer, 72, 849(1995))としても有用であることが報告されている。
【0004】
以上のことから、PARP阻害活性を有する化合物は、PARPの過剰な活性化に起因する疾患、例えば、種々の虚血性疾患(脳梗塞、心筋梗塞、急性腎不全等)、炎症性疾患(炎症性腸疾患、多発性脳硬化症、関節炎、慢性関節リュウマチ等)、神経変性疾患(アルツハイマー病、ハンチントン舞踏病、パーキンソン病等)、糖尿病、敗血症性ショック、頭部外傷等の予防および/または治療剤として有用であることが期待される。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a novel 4-aryl-5-hydroxyisoquinoline derivative having excellent PARP inhibitory activity, an addition salt thereof, and a method for producing the same.
[0002]
BACKGROUND OF THE INVENTION
Poly (ADP-ribose) synthase (poly (ADP-ribose) polymerase; hereinafter abbreviated as “PARP”) is a nuclear DNA function regulating protein, and is activated by recognizing DNA damage, It is an enzyme that sequentially binds poly (ADP-ribose) to an acceptor protein such as DNA-polymerase using NAD (nicotinamide @ adeneine @ dinucleotide), which is an essential component in the enzyme, as an enzyme substrate. Therefore, excessive activation of PARP is thought to cause a decrease in intracellular energy producing ability based on depletion of NAD essential for the electron transport system, leading to cell death (C. Szabo, Free Radic. Biol). .. Med., $ 21, $ 855 (1996)). In addition, PARP has been attracting attention as an apoptosis-related enzyme because PARP is a substrate of caspase-3, which is a member of the interleukin-1β converting enzyme-like protease family, and is limitedly degraded.
[0003]
Furthermore, in an experiment using a PARP-knockout mouse, cultured neurons collected from the brain of the knockout mouse were not affected by excitatory amino acids such as nitric oxide and NMDA (N-methyl-D-aspartate). It has been reported that the knockout mouse exhibits a remarkable protective effect of suppressing cerebral infarction caused by cerebral ischemia by about 80% or more (MJL {Eliason et al. , {Nature} Med., 3, $ 1089 (1997)). From these facts, it is considered that PARP inhibitors are effective for cerebral infarction and neurodegenerative diseases (Alzheimer's disease, Huntington's disease, Parkinson's disease, etc.). In addition to these, it is also useful for diseases such as diabetes, ischemia or ischemia-reperfusion such as myocardial infarction and acute renal failure, circulatory diseases such as septic shock, inflammatory diseases such as rheumatoid arthritis and multiple sclerosis. It has been reported that it is effective (C. Szabo et al., Trend Pharmacol Sci., 19, 287 (1998)). PARP inhibitors include antiretroviral agents including HIV (G.A. Cole et al., Biochem. Biophys. Res. Commun., 180, 504 (1991)) and sensitizers for anticancer therapy (C. Arundel-Suto, @ et @ al., @ Radiat. @ Res., $ 126, $ 367 (1991); S. @ Bolton @ et @ al., @ Br. @ J. Cancer, $ 72, $ 849 (1995)). I have.
[0004]
From the above, compounds having PARP inhibitory activity are useful for diseases caused by excessive PARP activation, such as various ischemic diseases (cerebral infarction, myocardial infarction, acute renal failure, etc.), inflammatory diseases (inflammatory Preventive and / or therapeutic agent for bowel disease, multiple sclerosis, arthritis, rheumatoid arthritis, etc., neurodegenerative disease (Alzheimer's disease, Huntington's chorea, Parkinson's disease, etc.), diabetes, septic shock, head trauma, etc. It is expected to be useful as.

The precipitate was collected on a glass fiber filter by suction filtration and washed 5 times with a 5% aqueous solution of trichloroacetic acid. Radioactivity on the filter was measured with a liquid scintillation counter. The enzyme activity in the absence of the test compound was defined as 100%, and the concentration of the test compound which reduced this to 50% (IC50Value) was calculated. (Koizumi J., et al., Jpn.
