Abstract

PROBLEM TO BE SOLVED: To provide a retinal pigment epithelial cell protectant.SOLUTION: The present invention provides a preventive or therapeutic agent for an eye disease caused by retinal pigment epithelial cell dysfunction or degeneration, the agent comprising (S)-4-fluoro-5-(2-methyl-1,4-diazepan-1-ylsulfonyl) isoquinoline represented by the following formula (1), its acid addition salt or their solvates as an active ingredient.

Description

本発明は、網膜色素上皮細胞障害若しくは変性による眼疾患の予防又は治療剤に関する。   The present invention relates to a preventive or therapeutic agent for eye diseases caused by retinal pigment epithelial cell damage or degeneration.

網膜は約0.1〜0.3mmの厚みを持ち、10種類の細胞群が層状に重なっている。このうち最も外側に位置する網膜色素上皮細胞は、脈絡膜と近接し、視細胞の機能維持に重要な役割を果たしている。従って網膜色素上皮細胞が様々な要因によって障害を受けると、著しい視覚機能低下を起こし、深刻な眼疾患へと至る。中でも加齢黄斑変性症では、網膜の中心部にある黄斑部が加齢に伴って障害・変性を受けるが、脈絡膜からの新生血管によって障害を受ける滲出型と新生血管を生じないが、黄斑部周辺の網膜色素上皮細胞が機能低下を起こし、徐々に変性していく萎縮型の二つのタイプが知られている。現在、滲出型に対する治療方法は複数の選択肢があり、直接的に新生血管の成長をくい止めるレーザー光凝固や光線力学療法、また血管新生に強く関与する血管内皮増殖因子(VEGF)を阻害する抗VEGF薬の投与などが行われており、一定の臨床成績を治めている。しかしながらもう一方のタイプである萎縮型に対する有効な治療方法は未だ確立されていない。
網膜色素変性症においても視細胞及び網膜色素上皮細胞が傷害されることで、暗順応障害(夜盲)や視野狭窄のような症状をきたすことを特徴とする遺伝性疾患であることが知られているが、未だ根本的な治療方法は確立されてない。
このように萎縮型加齢黄斑変性症や網膜色素変性症は、網膜色素上皮細胞の障害が主な原因となって起こるので、網膜色素上皮細胞そのものを保護するような薬剤があれば、新たな治療薬としての期待が持たれる。
The retina has a thickness of about 0.1 to 0.3 mm, and 10 types of cell groups are layered. Of these, the outermost retinal pigment epithelial cells are close to the choroid and play an important role in maintaining the function of the photoreceptor cells. Therefore, when the retinal pigment epithelial cells are damaged by various factors, the visual function is significantly lowered, leading to serious eye diseases. In particular, in age-related macular degeneration, the macula in the central part of the retina is damaged and degenerated with age, but the exudate and new blood vessels that are damaged by new blood vessels from the choroid do not form, but the macular region Two types of atrophy are known, in which peripheral retinal pigment epithelial cells undergo functional deterioration and gradually degenerate. Currently, there are multiple options for the treatment of exudative type, laser photocoagulation and photodynamic therapy that directly block the growth of new blood vessels, and anti-VEGF that inhibits vascular endothelial growth factor (VEGF), which is strongly involved in angiogenesis Medicine is administered, and certain clinical results are governed. However, an effective treatment method for the other type of atrophic type has not yet been established.
Retinitis pigmentosa is also known to be a hereditary disease characterized by symptoms such as dark adaptation disorder (night blindness) and visual field stenosis due to damage to photoreceptor cells and retinal pigment epithelial cells. However, a fundamental treatment method has not been established yet.
As described above, atrophic age-related macular degeneration and retinitis pigmentosa occur mainly due to retinal pigment epithelial cell damage. Therefore, if there is a drug that protects retinal pigment epithelial cells themselves, Expectation as a therapeutic drug.

一方、下記式(1)で表される(S)−4−フルオロ−5−(2−メチル−1,4−ジアゼパン−1−イルスルホニル)イソキノリン(以下、化合物1)は、脳梗塞、脳出血、くも膜下出血、脳浮腫等の脳血管障害の予防及び治療剤、特に緑内障の予防及び治療剤として有用であることが示されているが(特許文献1〜5参照)、網膜色素上皮細胞に対する保護作用については全く開示されていない。   On the other hand, (S) -4-fluoro-5- (2-methyl-1,4-diazepan-1-ylsulfonyl) isoquinoline (hereinafter referred to as Compound 1) represented by the following formula (1) is used for cerebral infarction and cerebral hemorrhage. It has been shown to be useful as a prophylactic and therapeutic agent for cerebrovascular disorders such as subarachnoid hemorrhage and cerebral edema, particularly glaucoma prophylactic and therapeutic agent (see Patent Documents 1 to 5). No protective action is disclosed.

(Test Example 1)
With reference to JP2012-6919A, the effect of Compound 1 on spermidine-induced retinal pigment epithelial cell death was evaluated.
Human retinal pigment epithelial cells (ARPE-19) were treated with Dulbecco's modified Eagle medium (hereinafter also referred to as “DMEM”) / Ham's F-12 medium containing 10% fetal bovine serum (hereinafter also referred to as “FBS”). The cells were cultured and seeded on a 96-well plate at 0.75 × 10 4 cells / 100 μL / well. After overnight culture under conditions of 37 ° C. and 5% CO 2 /95% Air, the medium was changed to 100 μL of spermidine (250 μM) -containing compound 1 (3 and 10 μM), and then 37 ° C., 5% CO 2 / The cells were cultured overnight under the condition of 95% Air. In addition, the group which melt | dissolved the compound 1 in DMSO and replaced | exchanged for 100 microliters 10% FBS containing DMEM / Ham's F-12 culture medium containing 0.1% DMSO was made into the normal control group. A group treated with a medium containing 100 μL spermidine (250 μM) containing 0.1% DMSO was designated as a solvent treatment group. 24 hours after the medium exchange, the number of viable cells was counted using Cell Counting Kit-8 (Dojindo Laboratories), and the cell death inhibition rate (%) was calculated according to the following formula 1. In addition, it subtracted from all the measured values by making the light absorbency of the well which not seed | inoculated the cell and added only the measurement solution into a blank. The number of examples in each group is 3.
