Description

本発明は、PARG阻害活性を有する新規なポリフェノール化合物又はそれらの薬理学的に許容される塩に関する。   The present invention relates to a novel polyphenol compound having PARG inhibitory activity or a pharmacologically acceptable salt thereof.

蛋白質の翻訳後修飾の一つであるADP−リボシル化は、ADP−リボシルトランスフェラーゼ(ART)によって触媒され、ニコチンアミドアデニンジヌクレオチド(NAD)を基質として、核蛋白質残基にADP−リボースを転移させる反応である。また、ポリADP−リボシル化反応では、ポリ(ADP−リボース)ポリメラーゼ(PARP)を触媒として、さらに次々にADP−リボース残基を伸張してポリ(ADP−リボース)となる。他方、ポリ(ADP−リボース)を特異的に分解する酵素であるポリ(ADP−リボース)グリコヒドロラーゼ(PARG)は、核及び細胞質に局在し、ポリ(ADP−リボース)のリボース−リボース結合を切断し、ADP−リボースを生成する。ポリADP−リボシル化反応は、細胞内では、PARPによる合成と、PARGによる分解によって調節されている。この反応は、細胞間の情報伝達やDNA修復、アポトーシスなど多くの細胞機能に関わっている。従って、PARPや、PARGの阻害剤は、抗がん剤や、抗がん剤の効果増強剤として期待される。 ADP-ribosylation, a post-translational modification of proteins, is catalyzed by ADP-ribosyltransferase (ART), and transfers ADP-ribose to nucleoprotein residues using nicotinamide adenine dinucleotide (NAD + ) as a substrate. Reaction. In the poly ADP-ribosylation reaction, poly (ADP-ribose) polymerase (PARP) is used as a catalyst to further extend ADP-ribose residues one after another to form poly (ADP-ribose). On the other hand, poly (ADP-ribose) glycohydrolase (PARG), an enzyme that specifically degrades poly (ADP-ribose), is localized in the nucleus and cytoplasm and binds the ribose-ribose bond of poly (ADP-ribose). Cleave to produce ADP-ribose. The poly ADP-ribosylation reaction is regulated in cells by synthesis by PARP and degradation by PARG. This reaction is involved in many cell functions such as information transfer between cells, DNA repair, and apoptosis. Therefore, PARP and PARG inhibitors are expected as anticancer agents and effect enhancers of anticancer agents.

例えば、下記式(A)で表わされるポリ(エテノADP−リボース)は、PARGによる分解耐性を有し、PARG阻害剤として知られている(例えば、特許文献1参照)。   For example, poly (ethenoADP-ribose) represented by the following formula (A) has a resistance to degradation by PARG and is known as a PARG inhibitor (see, for example, Patent Document 1).

PARGのN末端側にグルタチオン−S−トランスフェラーゼ融合型の完全長136kDa(RPG300−PGEX4T#11)を用い大腸菌で発現させ、下川らの方法(J.Biochm(Tokyo)1999、126:748−755)を参考に下記のようGSH−セファロースを用いてアフィニティー精製を行った。まず、LB培地−100μg/mlアンピシリンの 500mL 培養液を調製し、最後に 1mL イソプロピル−β−チオガラクトピラノシドを加えて発現誘導し、3時間培養した。6000g、4℃、15分間遠心分離し、沈殿させ、緩衝液A[20mL リン酸カリウム(pH7.5)、10mL β−メルカプトエタノール、150mL NaCl]で洗浄して、7000g、4℃、10分間遠心分離し、沈殿に、緩衝液AにComplete(Roche社)及び終濃度1mg/mL 卵白リゾチーム(Sigma社)を加え、氷上で10分間保温後 、トリトンX−100を終濃度1%、NaClを0.4Mとなるように加え、よく攪拌後、超音波破砕を氷水中で10秒間、3回行った。10,000gで30分間遠心して、上清と沈殿に分けた。上清に0.1%硫酸プロタミンを加え、4℃で1時間攪拌した後、10,000gで1時間遠心し、上清に緩衝液B[20mL リン酸カリウム(pH7.5)、10mL β−メルカプトエタノール、0.1% トリトンX−100]を150mL NaCl濃度となるように加え、GSH−セファロース 4B樹脂(Amersham社)10mlを添加後、1時間、4℃で転倒混和した。500gで5分遠心分離後、上清を除去し、緩衝液C[20mM リン酸カリウム(pH7.5)、10mM β−メルカプトエタノール、150mL NaCl]を加え、転倒混和後、500gで5分遠心分離後、上清除去を4回繰り返した。次に、溶出緩衝液を加えて500gで5分遠心分離後、上清除去を4回繰り返して溶出した後、セントリコン−50(Amicon社)を用いて濃縮した。緩衝液D[50mM リン酸カリウム(pH7.5)、10%グリセロール、0.05%トリトンX−100、10mM β−メルカプトエタノール]を入れて−80℃において保存した。
For PARG activity, recombinant PARG was prepared by the following method and used.
It was expressed in Escherichia coli using glutathione-S-transferase fusion full length 136 kDa (RPG300-PGEX4T # 11) on the N-terminal side of PARG, and the method of Shimokawa et al. (J. Biochm (Tokyo) 1999, 126: 748-755). As shown below, affinity purification was performed using GSH-Sepharose. First, a 500 mL culture solution of LB medium-100 μg / ml ampicillin was prepared, and finally, 1 mL isopropyl-β-thiogalactopyranoside was added to induce expression, followed by culturing for 3 hours. Centrifuge at 6000 g, 4 ° C. for 15 minutes, precipitate, wash with buffer A [20 mL potassium phosphate (pH 7.5), 10 mL β-mercaptoethanol, 150 mL NaCl], and centrifuge at 7000 g, 4 ° C., 10 minutes. The precipitate was separated, and Complete (Roche) and final concentration of 1 mg / mL egg white lysozyme (Sigma) were added to Buffer A. After incubation on ice for 10 minutes, Triton X-100 was adjusted to a final concentration of 1% and NaCl to 0%. Then, the mixture was stirred well and then ultrasonically crushed in ice water for 3 seconds for 10 seconds. Centrifugation was performed at 10,000 g for 30 minutes to separate the supernatant and the precipitate. To the supernatant was added 0.1% protamine sulfate, and the mixture was stirred at 4 ° C. for 1 hour, centrifuged at 10,000 g for 1 hour, and buffer B [20 mL potassium phosphate (pH 7.5), 10 mL β- Mercaptoethanol, 0.1% Triton X-100] was added to a concentration of 150 mL NaCl, 10 ml of GSH-Sepharose 4B resin (Amersham) was added, and the mixture was mixed by inversion at 4 ° C. for 1 hour. After centrifuging at 500 g for 5 minutes, the supernatant is removed, buffer C [20 mM potassium phosphate (pH 7.5), 10 mM β-mercaptoethanol, 150 mL NaCl] is added, and the mixture is inverted and centrifuged at 500 g for 5 minutes. Thereafter, supernatant removal was repeated 4 times. Next, an elution buffer was added, and the mixture was centrifuged at 500 g for 5 minutes, and then supernatant removal was repeated 4 times for elution, followed by concentration using Centricon-50 (Amicon). Buffer D [50 mM potassium phosphate (pH 7.5), 10% glycerol, 0.05% Triton X-100, 10 mM β-mercaptoethanol] was added and stored at −80 ° C.

32P]ポリ(ADP−リボース)は、下川らの方法(Organic Chemistry Insights、2009、2:1−5)を用いて、[32P]−NADを用いて作成した。反応混合液[20mM リン酸カリウム(pH7.5)、50mL KCl、4.0μM [32P]ポリ(ADP−リボース)]に、PARG阻害の試験化合物を加え、GST−PARG 15ngを加えて20μLとした。30℃で30分間インキュベーション後に、最終濃度1%になるようにSDSを加えて反応を終了させた。反応液をポリエチレンイミン−セルロースTLCプレート(Macherey−Nagel社)に2μLをスポットし、展開溶液(0.1M LiCl、3M 酢酸、3M 尿素)で展開を行った。放射能を富士イメージングプレート(富士フイルム社)に感光し、BAS−2500(富士フイルム社)によって解析を行った。 [ 32 P] poly (ADP-ribose) was prepared using [ 32 P] -NAD using the method of Shimokawa et al. (Organic Chemistry Insights, 2009, 2: 1-5). To the reaction mixture [20 mM potassium phosphate (pH 7.5), 50 mL KCl, 4.0 μM [ 32 P] poly (ADP-ribose)], a test compound for PARG inhibition was added, and 15 μg of GST-PARG was added to obtain 20 μL. did. After incubation at 30 ° C. for 30 minutes, SDS was added to a final concentration of 1% to terminate the reaction. 2 μL of the reaction solution was spotted on a polyethyleneimine-cellulose TLC plate (Machery-Nagel) and developed with a developing solution (0.1 M LiCl, 3 M acetic acid, 3 M urea). Radioactivity was exposed to Fuji Imaging Plate (Fuji Film) and analyzed by BAS-2500 (Fuji Film).

放射能の強さは、そのまま検出されるスポットの濃度に反映されるため、反応液をスポットした原点と、反応生成物が検出される領域の濃度を計測し、全体に占める分解産物の割合を計測した。すなわち未分解物は反応液をスポットした原点に残り、PARGにより分解された[32P]ADP−リボースはRf0.22のスポットとなる。
ポリ(ADP−リボース)分解活性は下記[式1]より算出した。
Since the intensity of radioactivity is reflected directly in the concentration of the spot detected, measure the origin where the reaction solution was spotted and the concentration of the area where the reaction product is detected, and determine the proportion of degradation products in the total. Measured. That is, the undegraded product remains at the origin of spotting the reaction solution, and [ 32 P] ADP-ribose decomposed by PARG becomes a spot of Rf 0.22.
The poly (ADP-ribose) degradation activity was calculated from the following [Formula 1].
