本発明は(6−{[4−(ピラゾール−1−イル)ベンジル](ピリジン−3−イルスルホニル)アミノメチル}ピリジン−2−イルアミノ)酢酸イソプロピルと他の緑内障若しくは高眼圧症の予防または治療薬とを組み合わせた緑内障若しくは高眼圧症の予防または治療剤、または眼圧下降剤に関するものである。 The present invention relates to the prevention or treatment of (6-{[4- (pyrazol-1-yl) benzyl] (pyridin-3-ylsulfonyl) aminomethyl} pyridin-2-ylamino) acetate and other glaucoma or ocular hypertension. The present invention relates to a preventive or therapeutic agent for glaucoma or ocular hypertension combined with a drug, or an intraocular pressure lowering agent.
緑内障は、種々の病因により眼圧が上昇し、眼球の内部組織(網膜、視神経など)が障害を受けることで失明に至る危険性のある難治性の眼疾患である。緑内障の治療方法としては、眼圧下降療法が一般的であり、その代表的なものとして薬物療法、レーザー治療法、手術療法などがある。 Glaucoma is a refractory eye disease that has a risk of leading to blindness due to increased intraocular pressure due to various etiologies and damage to internal tissues of the eyeball (retina, optic nerve, etc.). As a method for treating glaucoma, intraocular pressure lowering therapy is generally used, and representative examples include drug therapy, laser therapy, and surgical therapy.
薬物療法には、交感神経作動薬(ジピベフリンなどの非選択性刺激薬、ブリモニジンなどのα2受容体作動薬)、交感神経遮断薬(チモロール、ベフノロール、カルテオロール、ニプラジロール、ベタキソロール、レボブノロール、メチプラノロール(Metipranolol)などのβ受容体遮断薬、塩酸ブナゾシンなどのα1受容体遮断薬)、副交感神経作動薬(ピロカルピンなど)、炭酸脱水酵素阻害薬(アセタゾラミドなど)、プロスタグランジン類(イソプロピルウノプロストン、ラタノプロスト、トラボプロスト、ビマトプロストなど)などの薬物が使用されている。また、Rhoキナーゼ阻害剤(SNJ−1656など)、アデノシン作動薬(INO−8875など)、セロトニン遮断薬(BVT−28949)などが新たな薬物として開発中である。また、これらの他にも、プロスタグランジンE2受容体サブタイプ2アゴニスト(EP2アゴニスト)に眼圧下降作用があることが知られており、高いEP2受容体選択性と強力なEP2アゴニスト作用を有するスルホンアミド化合物が緑内障の治療薬として有望であることが国際公開第2010/113957号(特許文献1)に報告されている。 Drug therapy, sympathomimetics (nonselective stimulants such as dipivefrin, alpha 2 receptor agonists, such as brimonidine), sympatholytic (timolol, befunolol, carteolol, nipradilol, betaxolol, levobunolol, Mechipurano roll (Metipranolol) beta receptor blockers such, alpha 1 receptor blockers such bunazosin hydrochloride), parasympathetic agonists (such as pilocarpine) and carbonic anhydrase inhibitors (acetazolamide), prostaglandins (isopropyl Uno Drugs such as prostone, latanoprost, travoprost, bimatoprost) are used. In addition, Rho kinase inhibitors (such as SNJ-1656), adenosine agonists (such as INO-8875), serotonin blockers (BVT-28949) and the like are under development as new drugs. In addition to these, it is known that prostaglandin E2 receptor subtype 2 agonist (EP2 agonist) has an intraocular pressure lowering action, and has high EP2 receptor selectivity and strong EP2 agonist action. It is reported in International Publication No. 2010/113957 (Patent Document 1) that a sulfonamide compound is promising as a therapeutic agent for glaucoma.
ところで、緑内障を治療する目的で眼圧下降作用を有する薬剤を組み合わせて使用することが複数報告されている。例えば、特許第2726672号公報(特許文献2)には、交感神経遮断薬とプロスタグランジン類の組み合わせの投与が報告されている。また、国際公開第2002/38158号(特許文献3)には、眼圧下降作用を有する薬剤をいくつか組み合わせて眼に投与することによる緑内障の治療方法が開示されている。さらに、国際公開第2004/019951号(特許文献4)には、Rhoキナーゼ阻害剤とプロスタグランジン類の組み合わせの投与が、国際公開第2004/045644号(特許文献5)にはRhoキナーゼ阻害剤およびβ受容体遮断薬の組み合わせの投与が報告されている。 By the way, in order to treat glaucoma, multiple reports have been made on the use of a combination of drugs having an action of lowering intraocular pressure. For example, Japanese Patent No. 2726672 (Patent Document 2) reports the administration of a combination of a sympathetic nerve blocker and a prostaglandin. In addition, International Publication No. 2002/38158 (Patent Document 3) discloses a method for treating glaucoma by administering a combination of several drugs having an action of lowering intraocular pressure to the eye. Furthermore, International Publication No. 2004/019951 (Patent Document 4) discloses administration of a combination of a Rho kinase inhibitor and prostaglandins, and International Publication No. 2004/045644 (Patent Document 5) discloses a Rho kinase inhibitor. And the combination of β receptor blockers have been reported.
しかしながら、いずれの文献にも高いEP2受容体選択性および強力なEP2アゴニスト作用を有する(6−{[4−(ピラゾール−1−イル)ベンジル](ピリジン−3−イルスルホニル)アミノメチル}ピリジン−2−イルアミノ)酢酸イソプロピルと他の緑内障若しくは高眼圧症の予防または治療薬との組み合わせを具体的に開示する報告はこれまでになく、当然、これらの組み合わせが眼圧に対してどのような効果を示すかについては一切知られていない。 However, in any document, (6-{[4- (pyrazol-1-yl) benzyl] (pyridin-3-ylsulfonyl) aminomethyl} pyridine- having high EP2 receptor selectivity and potent EP2 agonist activity To date, there have been no reports that specifically disclose combinations of 2-ylamino) isopropyl acetate with other glaucoma or ocular hypertension preventive or therapeutic agents, and of course what effect these combinations have on intraocular pressure.

(結果および考察)
各投与群の点眼後4時間の眼圧下降幅(対コントロール群平均値)を表1に示す。眼圧下降幅(対コントロール群平均値)は、コントロール群の初期眼圧値からの眼圧値変動幅(ΔIOP)の平均値と各個体のΔIOPの差を各群ともに6羽の平均値で示す。
(Results and Discussion)
Table 1 shows the intraocular pressure drop width (vs. the control group average value) 4 hours after instillation in each administration group. Intraocular pressure drop (vs. control group average value) indicates the difference between the average value of intraocular pressure variation (ΔIOP) from the initial intraocular pressure value of the control group and ΔIOP of each individual as an average value of 6 birds in each group .
表1から明らかなように、本化合物とチモロールの併用投与群の点眼後4時間の眼圧下降幅(対コントロール群平均値)は、薬剤単独投与群、すなわち、本化合物投与群およびチモロール投与群の点眼後4時間の眼圧下降幅(対コントロール群平均値)よりも大きく、かつ、各薬剤単独投与によりひきおこされる点眼後4時間の眼圧下降幅(対コントロール群平均値)を合算した和よりも大きくなり、本化合物とチモロールの併用効果は相乗的なものであった。 As is apparent from Table 1, the intraocular pressure drop width (versus the control group average value) in the 4-hour post-instillation period of the combined administration group of the present compound and timolol was compared with that of the drug alone administration group, that is, the present compound administration group and timolol administration group. It is greater than the sum of the decrease in intraocular pressure for 4 hours after instillation (vs. the average value for the control group) and the sum of the decrease in intraocular pressure for 4 hours after instillation (vs. the average value for the control group) The combined effect of this compound and timolol was synergistic.
以上から、本化合物とβ受容体遮断薬を組み合わせることにより、相乗的な眼圧下降効果が得られることがわかった。 From the above, it was found that a synergistic intraocular pressure lowering effect can be obtained by combining this compound and a β receptor blocker.

(Results and Discussion)
Table 3 shows the decrease in intraocular pressure for 2 hours after instillation (vs. control group average value) in each administration group. The decrease in intraocular pressure (vs. control group average value) represents the difference between the average value of intraocular pressure fluctuation (ΔIOP) from the initial intraocular pressure value of the control group and ΔIOP of each individual as the average value of 6 animals in each group.
表3から明らかなように、本化合物とブリモニジンの併用投与群の点眼後2時間の眼圧下降幅(対コントロール群平均値)は、薬剤単独投与群、すなわち、本化合物投与群およびブリモニジン投与群の点眼後2時間の眼圧下降幅(対コントロール群平均値)よりも大きくかつ、各薬剤単独投与によりひきおこされる点眼後2時間の眼圧下降幅(対コントロール群平均値)を合算した和よりも大きくなり、本化合物とブリモニジンの併用効果は相乗的なものであった。 As is clear from Table 3, the intraocular pressure drop width (versus the control group average value) in the 2 hours after instillation of the combination administration group of this compound and brimonidine was compared with that of the drug alone administration group, that is, the present compound administration group and the brimonidine administration group. It is larger than the intraocular pressure decrease width (vs. control group average value) 2 hours after instillation and larger than the sum of the intraocular pressure decrease widths (vs. control group average value) 2 hours after instillation caused by administration of each drug alone. Thus, the combined effect of this compound and brimonidine was synergistic.
以上から、本化合物とα2受容体作動薬を組み合わせることにより、相乗的な眼圧下降効果が得られることがわかった。 From the above, it was found that a synergistic intraocular pressure lowering effect can be obtained by combining this compound and an α 2 receptor agonist.

[3] Single administration of brinzolamide The test was carried out in the same manner as in the above combined administration test, except that the compound solution was replaced with a base.
〔4〕コントロール
本化合物溶液を基剤に、ブリンゾラミド溶液を生理食塩水に代え、他は上記併用投与試験と同じ方法で試験をした。
[4] Control The present compound solution was used as a base, the brinzolamide solution was replaced with physiological saline, and the others were tested in the same manner as the above combined administration test.
(結果および考察)
各投与群の点眼後4時間の眼圧下降幅(対コントロール群平均値)を表4に示す。眼圧下降幅(対コントロール群平均値)は、コントロール群の初期眼圧値からの眼圧値変動幅(ΔIOP)の平均値と各個体のΔIOPの差を各群5もしくは6頭の平均値で示す。
(Results and Discussion)
Table 4 shows the decrease in intraocular pressure (vs. control group average value) 4 hours after instillation in each administration group. Intraocular pressure drop (vs. control group average value) is the difference between the average value of intraocular pressure value fluctuation (ΔIOP) from the initial intraocular pressure value of the control group and ΔIOP of each individual as the average value of 5 or 6 animals in each group Show.
表4から明らかなように、本化合物とブリンゾラミドの併用投与群の点眼後4時間の眼圧下降幅(対コントロール群平均値)は、薬剤単独投与群、すなわち、本化合物投与群およびブリンゾラミド投与群の点眼後4時間の眼圧下降幅(対コントロール群平均値)よりも大きかった。 As apparent from Table 4, the decrease in intraocular pressure (average value for the control group) in the 4-hour post-instillation period of the combined administration group of this compound and brinzolamide was as compared with that of the drug alone administration group, that is, the present compound administration group and the brinzolamide administration group. It was greater than the decrease in intraocular pressure 4 hours after instillation (vs. the control group average value).
以上から、本化合物と炭酸脱水酵素阻害剤を組み合わせることにより、強力な眼圧下降効果が得られることが分かった。 From the above, it was found that a strong intraocular pressure lowering effect can be obtained by combining this compound with a carbonic anhydrase inhibitor.
