- Glaucoma is an eye disease characterized by temporary or permanent visual field loss and visual impairment that causes decreased visual acuity. This is because the aqueous humor accumulates due to the circulatory disturbance of the aqueous humor, and the intraocular pressure continuously increases, and thus the optic nerve is compressed.
- it is effective to lower the intraocular pressure, and in order to lower the intraocular pressure, for example, drug treatment (eye drops, internal medicine, drip treatment), laser treatment, and surgical treatment are performed.
- PGFs and PGIs are known as those that reduce intraocular pressure.
- Development of these derivatives as a therapeutic agent for glaucoma and ocular hypertension has been promoted, and there are actually commercially available drugs (for example, latanoprost).
- existing glaucoma treatment drugs may not be sufficient to lower the intraocular pressure alone, and in the field of glaucoma treatment, a higher intraocular pressure lowering action is sought, and high concentrations or different mechanisms of action are required. Since drug combination therapy is performed, side effects are feared. Therefore, there is a demand for a drug that has a stronger action for lowering intraocular pressure and is highly safe.

(1)インビトロ(in vitro)試験
各種マウスプロスタノイド受容体をそれぞれ強制発現させたCHO細胞(それぞれFP-CHO、EP2-CHO、EP4-CHOおよびIP-CHO)を用いて、FPについては細胞内カルシウム濃度、IP、EP2およびEP4については細胞内サイクリックAMP(以下、cAMPと略記する。)産生量を指標に、各種プロスタノイド受容体に対する被験化合物のアゴニスト活性を検討した。
被験化合物および対照物質(PGE2、PGF2αおよびイロプロスト)は、ジメチルスルホキシド(DMSO)にて溶解し、10mmol/L溶液を調製した。調製した10mmol/L溶液は、使用時に10mmol/L溶液を解凍し、DMSOを用いて段階希釈を行い、測定用緩衝溶液もしくは測定用緩衝溶液2にて希釈して実験に供した。
各種マウスプロスタノイド受容体強制発現細胞は、非働化(56℃、30分)した9.8vol% 透析FBS(dialysed-FBS)(Invitrogen社)およびペニシリン-ストレプトマイシン-グルタミン(penicillin-streptomycin-glutamine)(GIBCO-BRL社)を含むα-MEM培地(Sigma社)(FP-CHO、EP2-CHOおよびEP4-CHO培養用)、もしくは非働化(56℃、30分)した9.8vol% dialysed-FBS(Invitrogen社)およびペニシリン-ストレプトマイシン-グルタミン(penicillin-streptomycin-glutamine)(Invitrogen社)を含む核酸含有α-MEM(Sigma社)(IP-CHO培養用)を用いて、5%CO2存在下、37℃で静置培養した。継代培養は以下の方法で行なった。
FP-CHOは、継代培養と同様の方法にて細胞を剥離および懸濁し、測定の2日前に、96穴UVプレートに、1ウェルあたり1.0×104個の細胞数となるよう播種し、5%CO2存在下、37℃で静置培養した。測定日に、96穴UVプレートの各ウェルから培地を除去した後、各ウェルをCa2+およびMg2+を含まないリン酸緩衝生理食塩水で1回洗浄した。各ウェルに5μmol/L fura 2-AM(DOJINDO社)、2.5mmol/L プロベネシド(Sigma社)、20μmol/L インドメタシン(Sigma社)および10mmol/L HEPES(Invitrogen社)を含む培地を100μL加え、CO2インキュベーター内で約60分間インキュベーションした。インキュベーション終了後、培地を除去し、測定用緩衝溶液(0.1w/v% ウシ血清アルブミン、2μmol/L インドメタシン、2.5mmol/L プロベネシドおよび20mmol/L HEPES(Invitrogen社)を含有したハンクス液(Hank’s balanced salt solution)(Invitrogen社))にて2回洗浄した。各ウェルに測定用緩衝溶液を120μL添加し、室温暗所で30分静置し安定化させ、実験に供した。
EP2-CHO、EP4-CHOおよびIP-CHOは、測定日に、培地を除去し、2mmol/L EDTAを含有するCa2+およびMg2+を含まないリン酸緩衝生理食塩水で1回洗浄した。適量の2mmol/L EDTAを含有するCa2+およびMg2+を含まないリン酸緩衝生理食塩水を加え、室温で約5分間インキュベーションし、細胞を剥離後、遠心管に細胞を回収し550g、3分間室温で遠心分離した後、上清を除去した。適量の測定用緩衝溶液1(1.0w/v% ウシ血清アルブミン(Sigma社)および2μmol/L ジクロフェナク(Sigma社)を含有したMEM培地(Invitrogen社))にて懸濁し、500g、3分間室温で遠心分離し、上清を除去した。測定用緩衝溶液2(1.0w/v% ウシ血清アルブミン(Sigma社)、2μmol/L ジクロフェナク(Sigma社)および1mmol/L 3-イソブチル-1-メチルキサンチンを含有したMEM培地(Invitrogen社))にて懸濁し、96穴1/2エリアプレートに1ウェル当たり5.0×104個の細胞数となるように25μLずつ分注した。種々の濃度のアゴニストを含む測定用緩衝溶液2を25μL添加し、室温で30分間反応させた。cAMP濃度の測定は、cAMP HTRF HiRangeキット(CIS bio International社)を用いて行った。キット説明書のTwo step protocolに従い、ライシス緩衝液(Lysis Buffer)にて希釈したcAMP-D2およびクリプターゼ(Cryptase)を25μLずつ添加し、1時間室温にてインキュベーションした。1時間のインキュベーション後に、Analyst GT(Molecular Device社)を用いて337nmにて励起した時の620nmおよび665nmにおける時間分解蛍光を測定し、その比(TRF ratio)を求めることで、検量線よりcAMP濃度を算出した。
以上の方法から得られた測定値を用いて、本発明化合物のマウスFP、マウスEP2、マウスEP4およびマウスIP受容体に対するアゴニスト活性の指標としてEC50値を算出した。
インビボ(in vivo)試験においては、当業者には容易に理解できることではあるが、いずれの被験化合物についても、活性本体であるカルボン酸は角膜透過性が悪いことから、エチルエステル体、イソプロピルエステル体等のエステル体に変換した化合物を点眼投与することによって、活性本体の薬理作用を評価した。なお、本願化合物群において、エステル体は、下記で薬理作用を確認する実験動物(ウサギ、イヌ等)において、点眼投与した後、房水中におけるカルボン酸の薬物濃度を測定することによって、当該エステル体が速やかに相当するカルボン酸に変換されることを確認した。
予め十分に馴化を行った雄性イヌ(TOYO Beagle)に、基剤(クエン酸緩衝液pH6.5、0.5%ポリソルベート80、1%プロピレングリコール、0.01%塩化ベンザルコニウム含)で0.003%(w/v)に調製した実施例16(1)の化合物を、それぞれ片眼に30μL点眼した。対眼は無処置とした。陽性対照化合物として、公知化合物であるラタノプロストを用いた。
雄性ウサギ(NewZealandWhite、2.0~3.0kg)に、基剤(クエン酸緩衝液pH6.5、0.5%ポリソルベート80、1%プロピレングリコール、0.01%塩化ベンザルコニウム含)で0.1%(w/v)に調製した実施例16(1)の化合物を、それぞれ片眼に30μL点眼した。その後、点眼0、1、2、4、6および8時間後の前房中の眼房水を採取し、房水中のタンパク質濃度を測定した。比較化合物として、上記した特許文献2記載の実施例12の化合物のメチルエステル体(すなわち、特許文献2記載の実施例10の化合物)(以下、比較化合物Cと略記することがある。)、および上記した比較化合物Bのメチルエステル体(すなわち、特許文献1記載の実施例1(F)の化合物の光学活性体(2S体))(以下、比較化合物Dと略記することがある。)を用いた。
覚醒下の雄性サル(カニクイザル)の左眼に、被験物質を上記と同様の基剤を用いて調製した溶液と、右眼には対照として基剤のみの溶液をそれぞれ30μL点眼投与した。投与後の眼圧を経時的に投与開始から24時間後まで測定した。眼圧測定の際には、カニクイザルをモンキーチェアーに保定後、眼科用表面麻酔剤(ベノキシール点眼液0.4%、参天製薬株式会社)を点眼投与して麻酔した。開瞼器(株式会社はんだや)を装着後、空圧圧平式眼圧計(モデル30クラシック、ライカート社)を用いて、両眼の眼圧を測定した(各群5~8例)。対照眼と被験物質を投与した眼との眼圧値の差を、以下の式を用いて眼圧下降率として算出し、測定中の最大眼圧下降率と24時間後の眼圧下降率を用いて、眼圧下降作用の持続性を評価した。被験物質の投与用量は、比較化合物Cは10μg/mL、および実施例16(1)は30μg/mLとした。
