Description

本発明は、縮合ピリダジン誘導体化合物に関する。
さらに詳しく言えば、本発明は
(1)一般式(I)

Figure 0004561698
(式中、すべての記号は後記と同じ意味を表わす。)で示されるピリダジン誘導体化合物、またはそれらの薬学的に許容される塩、
(2)それらの製造方法、および
(3)それらを有効成分として含有する薬剤に関する。 The present invention relates to a fused pyridazine derivative compound.
More specifically, the present invention relates to (1) general formula (I)
Figure 0004561698
(Wherein all symbols have the same meanings as described later), or a pharmaceutically acceptable salt thereof,
(2) It relates to a production method thereof, and (3) a drug containing them as an active ingredient.

ポリ(ADP−リボース)ポリメラーゼ(以下、PARPと略す。)はDNA損傷に依存して活性化される特異的な核内酵素であり、ニコチンアミドアデニンジヌクレオチド(以下、NAD+と略す。)のADP−リボースをヒストン、DNA−ポリメラーゼ、DNA−トポイソメラーゼ等のタンパク質に転移する反応を司っている。
ところで、DNAがペルオキシナイトライト(ONOO−)や活性酸素等により損傷を受けると、PARPの異常活性化(ニックの入ったDNAがPARPのZnフィンガードメインに結合すると100倍にも活性化される。)が起こり、電子伝達系に必須のNAD+の枯渇が生じ、ATPが減少してエネルギー産生系の破綻が起こることにより、細胞死が起こると考えられている(PARP自殺仮説:Free Radic. Biol. Med., 21, 855 (1996) ; TIPS., 19, 287 (1998)参照)。従って、PARP阻害剤は細胞死抑制剤として有用であると考えられる。
Poly (ADP-ribose) polymerase (hereinafter abbreviated as PARP) is a specific nuclear enzyme activated depending on DNA damage, and is a nicotinamide adenine dinucleotide (hereinafter abbreviated as NAD + ). It is responsible for the transfer of ADP-ribose to proteins such as histone, DNA-polymerase, DNA-topoisomerase.
By the way, when DNA is damaged by peroxynitrite (ONOO-), active oxygen, or the like, abnormal activation of PARP (when nicked DNA binds to the Zn finger domain of PARP, it is activated 100 times). ) Occurs, cell depletion occurs due to the depletion of NAD + , which is essential for the electron transport system, and ATP decreases and the energy production system fails (PARP suicide hypothesis: Free Radic. Biol Med., 21 , 855 (1996); TIPS., 19 , 287 (1998)). Therefore, PARP inhibitors are considered useful as cell death inhibitors.

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(Cell., 81, 801 (1995)参照)ことからアポトーシスに関連しているとも言われている。
さらにPARP阻害剤として一般的に知られている3−アミノベンズアミドやニコチンアミド等は、イン・ビトロ(in vitro)およびイン・ビボ(in vivo)での検討やPARPノックアウトマウスを用いた実験より、脳、心臓、消化管、骨格筋および網膜等の虚血性疾患、関節炎、炎症性腸疾患および多発性脳硬化症等の炎症性疾患、糖尿病、ショック、錐体外路系障害(TIPS., 19, 287 (1998) ; Eur. J. Pharmacol., 350, 1 (1998)参照)、痛覚過敏(Pain., 72, 355 (1997)参照)といった種々の病態モデルにおいて、細胞死抑制作用ならびに病態の改善作用を有することが報告されている。また、PARP阻害剤はHIVを含む抗レトロウイルス剤(Biochem. Biophys. Res. Commun., 180, 504 (1991)参照)、抗癌療法の増感剤(Radiat. Res., 126, 367 (1991) ; Br. J. Cancer., 72, 849 (1995)参照)や免疫抑制剤(Int. J. Immunopharmac., 17, 265 (1995)参照)としても有用であることが報告されている。
In addition, PARP is related to apoptosis because it is cleaved as a substrate of caspase-3 which is one of the interleukin-1β converting enzyme-like protease family (see Cell., 81 , 801 (1995)). It is also said.
Furthermore, 3-aminobenzamide, nicotinamide, etc., which are generally known as PARP inhibitors, have been studied in vitro (in vitro) and in vivo (in vivo) and from experiments using PARP knockout mice. Ischemic diseases such as brain, heart, gastrointestinal tract, skeletal muscle and retina, inflammatory diseases such as arthritis, inflammatory bowel disease and multiple sclerosis, diabetes, shock, extrapyramidal disorders (TIPS., 19 , 287 (1998); Eur. J. Pharmacol., 350 , 1 (1998)), hyperalgesia (Pain., 72 , 355 (1997)) It has been reported to have an effect. In addition, PARP inhibitors include HIV-containing antiretroviral agents (see Biochem. Biophys. Res. Commun., 180 , 504 (1991)) and anticancer therapy sensitizers (Radiat. Res., 126 , 367 (1991). ); Br. J. Cancer., 72 , 849 (1995)) and immunosuppressants (see Int. J. Immunopharmac., 17 , 265 (1995)).

以上のことから、PARP阻害活性を有する化合物は、虚血性疾患(脳梗塞、心筋梗塞、再灌流傷害、術後障害等)、炎症性疾患(炎症性腸疾患、多発性脳硬化症、関節炎、肺障害等)、神経変性疾患(錐体外路系障害、パーキンソン病、アルツハイマー病、筋ジストロフィー、腰部脊柱管狭窄症等)、緑内障、糖尿病、糖尿病合併症、ショック、頭部外傷、脊髄損傷、腎不全、痛覚過敏、血流障害等の予防および/または治療剤として有用であり、また、抗レトロウイルス剤(HIV等)、抗癌療法の増感剤や免疫抑制剤としても有用である。   From the above, compounds having PARP inhibitory activity are ischemic diseases (cerebral infarction, myocardial infarction, reperfusion injury, postoperative disorder, etc.), inflammatory diseases (inflammatory bowel disease, multiple cerebral sclerosis, arthritis, Lung disorders etc.), neurodegenerative diseases (extrapyramidal disorders, Parkinson's disease, Alzheimer's disease, muscular dystrophy, lumbar spinal canal stenosis, etc.), glaucoma, diabetes, diabetic complications, shock, head trauma, spinal cord injury, renal failure It is useful as a prophylactic and / or therapeutic agent for hyperalgesia, blood flow disorder, etc., and is also useful as an antiretroviral agent (such as HIV), a sensitizer for anticancer therapy, and an immunosuppressive agent.

実施例3で製造した化合物(537mg)のエタノール(4mL)溶液に、塩化スズ・二水和物(2.07g)を加え、30分間還流した。反応混合物を室温まで放冷後、飽和炭酸水素ナトリウム水溶液を加え、酢酸エチルで抽出した。抽出液を飽和食塩水で洗浄し、無水硫酸マグネシウムで乾燥後、濃縮した。得られた固体(137mg)をメタノール(2mL)に加えた後、4N塩化水素−ジオキサン溶液(0.26mL)を加え、室温で3時間撹拌した。反応混合物を濃縮した。残渣を混合溶媒(イソプロパノール:エタノール=4:1)で再結晶し、下記物性値を有する本発明化合物(144mg)を得た。さらに公知の方法によってメタンスルホン酸塩に変換した。
Example 6
4- (3-Aminophenyl) -6,7,9,9a-tetrahydro [1,4] thiazino [4,3-d] [1,2,4] triazin-1 (2H) -one In Example 3 To a solution of the prepared compound (537 mg) in ethanol (4 mL) was added tin chloride dihydrate (2.07 g), and the mixture was refluxed for 30 minutes. The reaction mixture was allowed to cool to room temperature, saturated aqueous sodium hydrogen carbonate solution was added, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated. The obtained solid (137 mg) was added to methanol (2 mL), 4N hydrogen chloride-dioxane solution (0.26 mL) was added, and the mixture was stirred at room temperature for 3 hr. The reaction mixture was concentrated. The residue was recrystallized with a mixed solvent (isopropanol: ethanol = 4: 1) to give the compound of the present invention (144 mg) having the following physical data. Further, it was converted into methanesulfonate by a known method.
