Description

本発明は医薬として有用なキノリルアルキルチオ基を有する新規環式化合物又はその塩に関する。それらの化合物は血管新生が関与する疾患の治療剤、特に癌、関節リウマチ、加齢性黄斑変性、糖尿病網膜症、未熟児網膜症、網膜静脈閉塞症、ポリープ状脈絡膜血管症、糖尿病黄斑浮腫、尋常性乾癬、粥状動脈硬化等の治療剤として有用である。   The present invention relates to a novel cyclic compound having a quinolylalkylthio group useful as a pharmaceutical or a salt thereof. These compounds are therapeutic agents for diseases involving angiogenesis, especially cancer, rheumatoid arthritis, age-related macular degeneration, diabetic retinopathy, retinopathy of prematurity, retinal vein occlusion, polypoidal choroidal angiopathy, diabetic macular edema, It is useful as a therapeutic agent for psoriasis vulgaris, atherosclerosis, etc.

血管新生とは既存の血管から新しい血管ネットワークが形成される現象であり、おもに細小血管で観察される。血管新生は本来生理的な現象であり、胎生期の血管形成にとって必須であるが、成人では通常、子宮内膜、卵胞等の限られた部位や創傷治癒の過程等の限られた時期にしか観察されない。ところが、癌、関節リウマチ、加齢性黄斑変性、糖尿病網膜症、未熟児網膜症、網膜静脈閉塞症、ポリープ状脈絡膜血管症、糖尿病黄斑浮腫、尋常性乾癬、粥状動脈硬化等の疾患において病的な血管新生が観察され、それらの疾患の病態進展と密接に関係している。血管新生はその促進因子と抑制因子のバランスにより調節されており、それらのバランスが崩れることにより血管新生が発生すると考えられている(非特許文献1、非特許文献2参照)。   Angiogenesis is a phenomenon in which a new blood vessel network is formed from existing blood vessels, and is mainly observed in small blood vessels. Angiogenesis is inherently a physiological phenomenon and is essential for embryonic angiogenesis, but in adults it is usually only at limited times, such as in the endometrium, follicles, and in the wound healing process. Not observed. However, in diseases such as cancer, rheumatoid arthritis, age-related macular degeneration, diabetic retinopathy, retinopathy of prematurity, retinal vein occlusion, polypoidal choroidal vasculopathy, diabetic macular edema, psoriasis vulgaris, atherosclerosis Angiogenesis is observed and is closely related to the pathological progression of these diseases. Angiogenesis is regulated by the balance between the promoting factor and the inhibitory factor, and it is considered that angiogenesis occurs when the balance is lost (see Non-Patent Document 1 and Non-Patent Document 2).

血管内皮細胞増殖因子(以下、『VEGF』とする)は、血管内皮細胞表面に存在する受容体(Flt-1、KDR/Flk-1等)に特異的に作用して、血管内皮細胞の増殖、遊走、管腔形成による毛細血管ネットワークの構築を促進する因子であり、血管新生の発生において非常に重要な役割を担っている。そのため、このVEGFを阻害して、血管新生の発生を制御することにより、血管新生が関与する疾患を治療する試みが数多く報告されている。このような治療に用いる薬物として、例えば、インドリン−2−オン誘導体(特許文献1参照)、フタラジン誘導体(特許文献2参照)、キナゾリン誘導体(特許文献3参照)、アントラニル酸アミド誘導体(特許文献4参照)、2−アミノニコチン酸誘導体(特許文献5参照)、4−ピリジルアルキルチオ誘導体(特許文献6参照)等を挙げることができる。   Vascular endothelial growth factor (hereinafter referred to as “VEGF”) specifically acts on receptors (Flt-1, KDR / Flk-1, etc.) present on the surface of vascular endothelial cells to proliferate vascular endothelial cells. It is a factor that promotes the construction of capillary networks through migration and tube formation, and plays a very important role in the development of angiogenesis. Therefore, many attempts have been reported to treat diseases involving angiogenesis by inhibiting the VEGF and controlling the occurrence of angiogenesis. Examples of drugs used for such treatment include indoline-2-one derivatives (see Patent Document 1), phthalazine derivatives (see Patent Document 2), quinazoline derivatives (see Patent Document 3), anthranilic acid amide derivatives (Patent Document 4). Reference), 2-aminonicotinic acid derivatives (see Patent Document 5), 4-pyridylalkylthio derivatives (see Patent Document 6), and the like.

しかし、これらの特許文献には、キノリルアルキルチオ基を有する環式化合物に関する記載はなされていない。   However, these patent documents do not describe a cyclic compound having a quinolylalkylthio group.

一方、キノリルアルキルチオ基を有する環式化合物に比較的近い化学構造を有する化合物が、特許文献7及び特許文献8に報告されている。特許文献7はアリールスルホンアミド誘導体に関するもので、その用途として神経変性疾患治療効果が開示されている。また、特許文献8は、置換複素環式化合物に関するもので、その用途としてp56lckタンパク質チロシンキナーゼ阻害作用が開示されている。しかし、いずれの特許文献においても膨大な組み合わせの化学構造が開示されているだけで、キノリルアルキルチオ基を有する環式化合物の具体的な開示は一切なされていない。

On the other hand, compounds having a chemical structure relatively close to a cyclic compound having a quinolylalkylthio group are reported in Patent Document 7 and Patent Document 8. Patent Document 7 relates to an arylsulfonamide derivative, and its therapeutic effect is disclosed as a neurodegenerative disease. Patent Document 8 relates to a substituted heterocyclic compound, and as its use, p56lck protein tyrosine kinase inhibitory action is disclosed. However, any patent document discloses only a huge number of chemical structures, and no specific disclosure of a cyclic compound having a quinolylalkylthio group is made.

At room temperature, 2-mercapto-N- (4-trifluoromethoxyphenyl) pyridine-3-carboxamide (reference compound 8-3, 52 mg, 0.17 mmol), 4- (chloromethyl) quinoline (reference compound 5-1, To a solution of 28 mg, 0.16 mmol) in anhydrous N, N-dimethylformamide (1.0 mL) was added triethylamine (66 μL, 0.47 mmol) and stirred for 18 hours. Ethyl acetate (50 mL) was added, and after washing with saturated aqueous sodium hydrogen carbonate (50 mL) and saturated brine (50 mL), the organic layer was dried over anhydrous magnesium sulfate. After evaporating the solvent under reduced pressure, the residue was purified by silica gel column chromatography to obtain the target compound (40 mg) as a white amorphous (yield 52%).
