- Emlicasan was accurately measured on a 45 mg electronic balance (AUW220D, SHIMADZU) and transferred to a glass test tube. 0.9 ml of 99% ethanol was added and dissolved therein. Vortex thoroughly to ensure complete dissolution. Polysorbate 80 (Tween 80: Polysorbate # 80, NIKKOL) as a surfactant was added to a final concentration of 0.5% and stirred sufficiently. Thereafter, ethanol was distilled off with a nitrogen stream. To adjust the osmotic pressure, concentrated glycerin was added to this solution to a final concentration of 1%.
- Phosphate buffer Phosphate buffered saline: PBS
- PBS Phosphate buffered saline
- the solution was sufficiently stirred, and 20 ml was collected and filtered through a 0.22 ⁇ m GV filter (Merck Millipore). The first 5 ml of the filtrate were discarded and the next 15 ml were collected.
- the filtrate was divided into 5 ml glass test tubes for 4 ° C., 25 ° C., and 37 ° C., protected from light with parafilm and aluminum foil, and stored at each temperature condition. The stability of this sample was examined by high performance liquid chromatography (High Performance Liquid Liquid Chromatography: HPLC, Shimadzu Corporation).
- HPLC conditions were as follows: acetonitrile containing 0.05% trifluoroacetic acid in a mobile phase and water were used at a ratio of 60:40, and the temperature of a VR-ODS column (4.6 ⁇ 150 mm, Shimadzu Corporation) was set to 40 ° C.
- the flow rate was 1.0 ml / min
- the detection wavelength was 254 nm
- the injection volume was 10 ⁇ l
- the detection time was 10 minutes. This time, the result of HPLC measurement immediately after preparation was taken as 100%, and the results after 2 weeks and after 4 weeks were compared and examined over time.
- pH 4.5 conditions were prepared and examined in the same manner as described above.
- FIG. 5 shows the results.
- emuricasan dissolved at both pH 4.5 and pH 5.5.
- pH 5.5 the amount of emuricasan present without decomposition in 25 weeks at 25 ° C. was less than 90%, but did not fall below 50% even after 4 weeks.
- pH 4.5 the emuricasan, which was not decomposed in 2 weeks at 25 ° C., did not fall below 90%.
- emlicasan showed decomposition at pH 4.5 and pH 5.5, suggesting that it may be unstable even under low pH conditions. Therefore, the stability was good at pH 4.5 as compared with other pH.
- Example 6 Lyophilization test of emulikasan ophthalmic solution
- emuricasan ophthalmic solution may be degraded when stored at room temperature for a long period of time in a pH range of 6 or more.
- the development of long-term stabilization techniques for the preparation of emricasan as eye drops has advantages in clinical use. Therefore, the development of a freeze-dried preparation was studied.
- Emlicasan was accurately measured on a 7 mg electronic balance (AUW220D, SHIMADZU) and transferred to a glass test tube. 140 ⁇ l of 99% ethanol was added and dissolved therein. Vortex thoroughly to ensure complete dissolution. Polysorbate 80 (Tween80: Polysorbate 80, NIKKOL) as a surfactant was added to a final concentration of 0.5%, and the mixture was sufficiently stirred. Thereafter, ethanol was distilled off with a nitrogen stream.
- D-mannitol (Wako Pure Chemical Industries, Ltd.) is dissolved in phosphate buffered saline (PBS) to a final concentration of 4.5%, adjusted to pH 4.5, and added to a total volume of 7 ml. did.
- PBS phosphate buffered saline
- the solution was allowed to stir well and stored in a -83 ° C freezer for one day. After freezing, the water was completely removed by a freeze dryer (FDU-1200, Tokyo Rikakikai Co., Ltd.) over 12 hours.
- the first 4 ml of the filtrate was discarded, and the next 8 ml was collected, divided into glass test tubes for initial values of 4 ° C., 25 ° C., and 37 ° C., and stored in a freezer at ⁇ 83 ° C. for one day. After freezing, the water was completely removed by a freeze dryer (FDU-1200, Tokyo Rikakikai Co., Ltd.) over 12 hours. The lyophilized powder was stored at each temperature condition, protected from light with parafilm and aluminum foil. The stability of this sample was examined by high performance liquid chromatography (High Performance Liquid Chromatography: HPLC, Shimadzu Corporation).
- HPLC conditions were as follows: acetonitrile containing 0.05% trifluoroacetic acid in a mobile phase and water were used at a ratio of 60:40, and the temperature of a VR-ODS column (4.6 ⁇ 150 mm, Shimadzu Corporation) was set to 40 ° C.
- the flow rate was 1.0 ml / min
- the detection wavelength was 254 nm
- the injection volume was 10 ⁇ l
- the detection time was 10 minutes. This time, the result of HPLC measurement immediately after preparation was taken as 100%, and the results after two weeks were compared and examined over time.
- emulikasan ophthalmic solution in a lyophilized formulation can be formulated as a formulation.
- Example 8 Preparation example of ophthalmic solution
- the ophthalmic solution is provided as lyophilized emricasan and a solvent for reconstitution thereof.
- Emricasan ophthalmic solution is prepared by mixing emlicasan, which has been freeze-dried immediately before use, with a reconstituting solvent in an ophthalmic container. After the preparation of emulikasan ophthalmic solution, it can be stored at room temperature for 2 weeks, for example.
- a solvent for reconstitution a 0.2% phosphate buffered ophthalmic base adjusted to pH 4.5 is used.
- the reconstitution solvent may include physiological saline and may further include a preservative.
- Example 9 in vivo test
- a mouse having a type 8 collagen mutation is used as a Fuchs corneal endothelial dystrophy model mouse (Col8a2 Q455K / Q455K ).
- the severity of Fuchs corneal endothelial dystrophy is graded from the corneal endothelium image before the eye drop test, and a 20 to 24 week old Fuchs corneal endothelial dystrophy model mouse having the same symptoms is used.
- Emuricasan ophthalmic solution (0.1% (pH 4.5), 0.5% (pH 7.0) prepared by dissolving lyophilized emurikasan with a phosphate buffer was applied to 45 mice every morning and evening.
- Two drops of 2 ⁇ l are applied to the left and right eyes twice.
- a phosphate buffer of pH 4.5 or pH 7.0 is used as a control.
- the instillation period is three months, during which the experimenter conducts the experiment in blind condition with respect to Emlikasan ophthalmic solution and control ophthalmic solution.
- the corneal endothelium image is observed with a contact type corneal endothelium specular to perform grading. Every four weeks after the start of the eye drop test, the corneal endothelium image of the mouse is observed using a contact type corneal endothelium specular to evaluate the usefulness of Emlikasan ophthalmic solution.
- Emuricasan is expected to have a therapeutic effect on corneal endothelial damage, and provides a technique that can be used particularly in the technical field related to ophthalmic preparations.

エムリカサンは難溶性であり、生理的食塩水、リン酸緩衝液、精製水などには点眼薬として使用するための濃度では溶解することが出来ない。そこで、各種の界面活性剤を用いてエムリカサンを溶解することができるかについて試験した。
本実施例では、エムリカサンの目標溶解濃度として、フックス角膜内皮ジストロフィの不死化細胞(iFECD)を用いたin vitro試験(国際公開第2017/110094号)において薬理活性を示した濃度10μmol/Lの1000倍となる10mmol/Lとした。エムリカサン粉末(Chemscene社)を正確に目標濃度分である28mgを電子天秤(AUW220D、SHIMADZU)で測りガラス試験管に移した。そこに99%エタノール100μlを添加し溶解させた。完全に溶解させるため、ボルテックスで十分に撹拌させた。その後、ポリオキシエチレン基を含む非イオン性界面活性剤であるポリソルベート80(Tween80:Polysorbate 80、NIKKOL)、ポリオキシエチレン硬化ヒマシ油60(HCO-60:Polyoxyethylene Hydrogenated Castor Oil 60、NIKKOL)、モノステアリン酸ポリエチレングリコール40(MYS-40:Polyetylene Glycol Monostearate 40、NIKKOL)を終濃度2%になるようにそれぞれ添加し十分に撹拌させた。この溶液にリン酸緩衝液(Phosphate buffered saline:PBS)を全量5mlになるように添加し十分に撹拌させ溶解性を目視により確認した。
結果を図1に示す。エムリカサンは酸性化合物であるため溶液のpH値が塩基性側ほど溶解性は高くなる。すなわち、酸性物質の場合、pHが塩基性になることでイオン形濃度が上昇し分子形濃度が減るので、溶解度が高くなる。界面活性剤を用いない条件ではpH値7.0~8.0の条件では沈殿を起こし溶解は確認できなかった。ポリオキシエチレン基を含む非イオン性界面活性剤としてTween80、HCO-60、MYS-40を用いたものでは、pH7条件において全て溶解することが確認できた。また、pH5.0の条件では界面活性剤を用いることでわずかに溶けたが、沈殿を起こし完全な溶解は確認できなかった。一方、HCO-60を用いたものは懸濁状態を維持し他の界面活性剤と比較し良好な結果であることが確認できた。10mmol/Lを目標溶解濃度として設定した場合、目視により溶解が確認できた溶媒の最低のpH値はpH6.0であった。したがって、本実施例における目標溶解濃度を達成するためには、終濃度2%のポリオキシエチレン基を含む非イオン性界面活性剤を用いることにより、最終pH6.0以上でエムリカサンを溶解させることができた。
エムリカサンは塩基性条件では分解される可能性があることが予測されるため、pH7.0よりも低いpHにおいての溶解性について試験した。
本実施例では、実施例1と同様に、エムリカサンの目標溶解濃度を10mmol/Lとした。エムリカサンを正確に28mgを電子天秤(AUW220D、SHIMADZU)で測りガラス試験管に移した。そこに99%エタノール100μlを添加し溶解させた。完全に溶解させるため、ボルテックスで十分に撹拌させた。その後、ポリオキシエチレン基を含む非イオン性界面活性剤であるポリオキシエチレン硬化ヒマシ油100(HCO-100:Polyoxyethylene Hydrogenated Castor Oil 100、NIKKOL)、ポリオキシエチレン硬化ヒマシ油60(HCO-60:Polyoxyethylene Hydrogenated Castor Oil 60、NIKKOL)、ポリオキシエチレン硬化ヒマシ油40(HCO-40:Polyoxyethylene Hydrogenated Castor Oil 40、NIKKOL)、ポリオキシエチレン硬化ヒマシ油20(HCO-20:Polyoxyethylene Hydrogenated Castor Oil 20、NIKKOL)、ポリオキシエチレンヒマシ油35(CO-35:Polyoxyethylene Castor Oil 35、NIKKOL)、モノステアリン酸ポリエチレングリコール40(MYS-40:Polyetylene Glycol Monostearate 40、NIKKOL)、ポリオキシエチレンポリオキシプロピレングリコール407(Poloxamer407:Polyoxyethylene Polyoxypropylene Glycol 407、NIKKOL)を終濃度0.5%になるように添加し十分に撹拌させた。この溶液にリン酸緩衝液(Phosphate buffered saline:PBS)を全量5mlになるように添加し十分に撹拌させ溶解性を目視により確認した。
結果を図2に示す。本実施例において使用した界面活性剤間で、エムリカサンの溶解性は同様の傾向を示した。界面活性剤の終濃度が0.5%である場合で、最終pHが6.5以上で溶解が確認できた。したがって、エムリカサンの溶解性はpHによる影響を受けやすいことが明らかになった。
実施例1および2において、ポリオキシエチレン基を含む非イオン性界面活性剤を用いて、特定のpH範囲で、エムリカサンが可溶化することが明らかになった。本実施例では、溶液中のエムリカサンの安定性を試験した。
エムリカサンをHCO-60を界面活性剤として用いて終濃度0.5%に溶解した際の安定性について試験した。エムリカサンを正確に500mg電子天秤(AUW220D、SHIMADZU)で測りガラス試験管に移した。そこに99%エタノール2mlを添加し溶解させた。完全に溶解させるため、ボルテックスで十分に撹拌させた。界面活性剤であるポリオキシエチレン硬化ヒマシ油60(HCO-60:Polyoxyethylene Hydrogenated Castor Oil 60、NIKKOL)を終濃度0.5%になるように添加し十分に撹拌させた。その後、エタノールを窒素気流により留去した。浸透圧を調整するため、この溶液に終濃度1%になるよう濃グリセリンを添加した。リン酸緩衝液(Phosphate buffered saline:PBS)をpH8に調整し全量100mlになるように添加した。その溶液を十分に撹拌させ、20mlを採取し0.22μmGVフィルター(メルクミリポア)で濾過した。最初の濾液5mlは廃棄し、次の15mlを採取した。この濾液を4℃、25℃、37℃用に5mlずつガラス製試験管に分け入れ、パラフィルムとアルミホイルで遮光し各温度条件に保存した。高速液体クロマトグラフィー(High Performance Liquid
Chromatography:HPLC、島津製作所)によりこのサンプルの安定性を検討した。HPLC条件は、移動相に0.05%トリフルオロ酢酸を含有させたアセトニトリルと水を60:40で使用し、VR-ODSカラム(4.6×150mm、株式会社島津製作所)の温度を40℃、流速を1.0ml/分、検出波長を254nm、注入量を10μl、検出時間を10分とした。今回、調製直後のHPLC測定結果を100%とし、2週間後、4週間後との結果を比較し経時的に安定性を評価した。また、pH7、pH6.5、pH6条件も上記同様の方法で調製し検討した。
結果を図3に示す。4℃条件では、分解せずに存在しているエムリカサンは4週間では90%を下回ることはなかった。しかし、25℃および37℃条件では、エムリカサンの分解が見られ、25℃および37℃では、エムリカサンが溶液中で不安定である可能性が示唆された(データは示さず)。また、試験した範囲内では、pHが高いほど安定性が低い結果になった。
(材料および方法)
エムリカサンをTween80を界面活性剤として用いて終濃度0.5%に溶解した際の安定性について試験した。エムリカサンを正確に500mg電子天秤(AUW220D、SHIMADZU)で測りガラス試験管に移した。そこに99%エタノール2mlを添加し溶解させた。完全に溶解させるため、ボルテックスで十分に撹拌させた。界面活性剤であるポリソルベート80(Tween80:Polysorbate 80、NIKKOL)を終濃度0.5%になるように添加し十分に撹拌させた。その後、エタノールを窒素気流により留去した。浸透圧を調整するため、この溶液に終濃度1%になるよう濃グリセリンを添加した。リン酸緩衝液(Phosphate buffered saline:PBS)をpH8に調整し全量100mlになるように添加した。その溶液を十分に撹拌させ、20mlを採取し0.22μmGVフィルター(メルクミリポア)で濾過した。最初の濾液5mlは廃棄し、次の15mlを採取した。この濾液を4℃、25℃、37℃用に5mlずつガラス製試験管に分け入れ、パラフィルムとアルミホイルで遮光し各温度条件に保存した。高速液体クロマトグラフィー(High Performance Liquid Chromatography:HPLC、島津製作所)によりこのサンプルの安定性を検討した。HPLC条件は、移動相に0.05%トリフルオロ酢酸を含有させたアセトニトリルと水を60:40で使用し、VR-ODSカラム(4.6×150mm、株式会社島津製作所)の温度を40℃、流速を1.0ml/分、検出波長を254nm、注入量を10μl、検出時間を10分とした。今回、調製直後のHPLC測定結果を100%とし、2週間後、4週間後との結果を比較し経時的に検討した。また、pH7、pH6.5、pH6条件も上記同様の方法で調製し検討した。
結果を図4に示す。4℃条件では、分解せずに存在しているエムリカサンは4週間では90%を下回ることはなかった。しかし、25℃および37℃条件では、エムリカサンの分解が見られ、25℃および37℃では、エムリカサンが溶液中で不安定である可能性が示唆された(データは示さず)また、pHが高いほど安定性が低い結果になった。これらの結果はHCO-60を用いた結果(実施例3)と同様の傾向であったが、Tween80がHCO-60と比較するとやや安定化傾向であった。
酸性領域下では酸性化合物であるエムリカサンの安定性が向上し、エムリカサンが分子型の形態をとることで眼内移行が向上し、反対にアルカリ性領域下ではエムリカサンがイオン型の形態をとることで眼内移行が低下することが予測される。したがって、酸性領域下におけるエムリカサンの安定性について検討した。
エムリカサンをTween80を界面活性剤として用いて終濃度0.1%に溶解した際の安定性について試験した。
結果を図5に示す。終濃度0.1%では、エムリカサンは、pH4.5およびpH5.5のいずれのpHでも溶解した。終濃度0.1%に溶解した場合には、4℃条件では、分解せずに存在しているエムリカサンはどのpHにおいても4週間では90%を下回ることはなかった。pH5.5では25℃条件において2週間で分解せずに存在しているエムリカサンは90%を下回ったが、4週間経過しても、50%を下回ることはなかった。一方、pH4.5では25℃条件において2週間で分解せずに存在しているエムリカサンは90%を下回ることはなかった。また、37℃での条件では、エムリカサンは、pH4.5およびpH5.5において分解を示し、低いpH条件下でも不安定である可能性が示唆された。したがって、pH4.5では他のpHと比較し安定性が良好であった。
エムリカサン点眼液はpH6以上の領域では長期的に室温保存すると分解される可能性があることが示された。点眼薬としてエムリカサンを調製するためには長期的に安定化させる手法を開発することで、臨床における使用において利点がある。そこで、凍結乾燥製剤の開発を検討した。
エムリカサンを正確に7mg電子天秤(AUW220D、SHIMADZU)で測りガラス試験管に移した。そこに99%エタノール140μlを添加し溶解させた。完全に溶解させるため、ボルテックスで十分に撹拌させた。界面活性剤であるポリソルベート80(Tween80:Polysorbate 80、NIKKOL)を終濃度0.5%になるように添加し十分に撹拌させた。その後、エタノールを窒素気流により留去した。この溶液に終濃度4.5%になるようD-マンニトール(和光純薬工業)をリン酸緩衝液(Phosphate buffered saline:PBS)に溶解させ、pH4.5に調整し全量7mlになるように添加した。その溶液を十分に撹拌させ、-83℃の冷凍庫で1日保存した。凍結後、凍結乾燥機(FDU-1200、東京理化器械株式会社)に12時間かけて完全に水分を飛ばした。
凍結乾燥直後のサンプルは、白色の粉末状であった。水を添加後、速やかに溶解したが淡白色であった。0.22μmGVフィルターで濾過後、凍結乾燥前の約88%量のエムリカサンが溶解していた。したがって、エムリカサンは、凍結乾燥が可能であり、水の再溶解にも耐えうることが明らかになった。 (実施例7:凍結乾燥製させたエムリカサンより調製した点眼液の安定性試験)
(材料および方法)
エムリカサンを正確に15mg電子天秤(AUW220D、SHIMADZU)で測りガラス試験管に移した。そこに99%エタノール300μlを添加し溶解させた。完全に溶解させるため、ボルテックスで十分に撹拌させた。界面活性剤であるポリソルベート80(Tween80:Polysorbate 80、NIKKOL)を終濃度0.5%になるように添加し十分に撹拌させた。その後、エタノールを窒素気流により留去した。この溶液に終濃度4.5%になるようD-マンニトール(和光純薬工業)をリン酸緩衝液(Phosphate buffered saline : PBS)に溶解させ、pH4.5に調整し全量15mlになるように添加した。その溶液を十分に撹拌させ、13mlを採取し0.22μmGVフィルター(メルクミリポア)で濾過した。最初の濾液4mlは廃棄し、次の8mlを採取し初期値、4℃、25℃、37℃用に2mlずつガラス製試験管に分け入れ、-83℃の冷凍庫で1日保存した。凍結後、凍結乾燥機(FDU-1200、東京理化器械株式会社)に12時間かけて完全に水分を飛ばした。パラフィルムとアルミホイルで遮光し、凍結乾燥粉末を各温度条件に保存した。高速液体クロマトグラフィー(High Performance Liquid Chromatography:HPLC、島津製作所)によりこのサンプルの安定性を検討した。HPLC条件は、移動相に0.05%トリフルオロ酢酸を含有させたアセトニトリルと水を60:40で使用し、VR-ODSカラム(4.6×150mm、株式会社島津製作所)の温度を40℃、流速を1.0ml/分、検出波長を254nm、注入量を10μl、検出時間を10分とした。今回、調製直後のHPLC測定結果を100%とし、2週間後との結果を比較し経時的に検討した。
本実施例で測定した結果から、凍結乾燥した状態の処方であれば安定性が保たれることがわかった。したがって、凍結乾燥製剤でのエムリカサン点眼液は製剤として成り得る。
点眼液は、凍結乾燥したエムリカサンおよびその再構成用溶媒として提供される。使用直前に凍結乾燥したエムリカサンを再構成用溶媒にて点眼容器内で混和することによりエムリカサン点眼液を調製する。エムリカサン点眼液調製後、例えば2週間室温保存して使用することができる。再構成用溶媒はpH4.5に調整された0.2%リン酸緩衝液点眼薬用基剤を用いる。再構成用溶媒は、生理食塩水を含んでもよく、防腐剤をさらに含んでもよい。
(マウスへの点眼試験)
フックス角膜内皮ジストロフィモデルマウスとして8型コラーゲンの変異を有するマウスを用いる(Col8a2Q455K/Q455K)。点眼試験前の角膜内皮像からフックス角膜内皮ジストロフィの重症度のグレーディングを行い、同程度の症状を持つ生後20~24週齢のフックス角膜内皮ジストロフィモデルマウスを用いる。凍結乾燥製したエムリカサンをリン酸緩衝液で溶解して調製したエムリカサン点眼液(0.1%(pH4.5)、0.5%(pH7.0))を、マウス45匹に対し毎日朝夕の2回、左右の眼に2μlずつ点眼する。コントロールにはpH4.5あるいはpH7.0リン酸緩衝液を用いる。点眼期間は3ヶ月としその間、実験担当者はエムリカサン点眼液およびコントロール点眼液についてブラインドの状態で実験を行う。
点眼試験開始前に、接触式角膜内皮スペキュラーで角膜内皮像を観察し、グレーディングを行う。点眼試験開始後4週間おきに、接触式角膜内皮スペキュラーを用いてマウスの角膜内皮像を観察し、エムリカサン点眼液の有用性を評価する。
フックス角膜内皮ジストロフィモデルマウスにおける接触式角膜内皮スペキュラーにより観察される角膜内皮細胞密度の減少が、コントロールと比べてエムリカサン点眼液を投与した個体では抑制されることが期待される。また、コントロールと比べてエムリカサン点眼液を投与した個体では、guttaeの面積の割合が減少することが期待される。
