リン酸カルシウム 90mg ステアリン酸マグネシウム 1.5mg
コーンスターチ 35mg ポリビニルピロリドン 10mg
総量 166.5mg
TSL−0319化合物と、リン酸カルシウム、コーンスターチ、ポリビニルピロリドン、ヒドロキシプロピルメチルセルロース及び指定量の半分のステアリン酸マグネシウムとを混合した。打錠機において、直径13ミリメートルの錠剤を作製してから、適切な設備を用いて、それを摩擦しながら、1.5ミリメートルのメッシュアンダーサイズを有するストレーナを通過するようにし、かつ残りのステアリン酸マグネシウムと混合した。打錠機においてこれらの顆粒をプレスして、所要の形状の錠剤を形成した。
コア重量:166.5mg パンチ:9ミリメートル、凸型
このように作製した錠剤コアを、基本的にヒドロキシプロピルメチルセルロースから構成されているフィルムでコーティングした。最終的に完成したフィルムコーティングをミツロウでポリッシングした。
コーティング錠剤の重量:175mg

常法によって、得られた薬物組成物を均一に混合した後、普通のゼラチンカプセルに装入して、1000粒のカプセルを得た。このような方法によって、5mgの化合物TSL−0319を含有するカプセルを得た。
ジペプチジルペプチダーゼIV(DPP−IV)は、室温下で、Gly−Pro−アミノルシフェリン(Gly−Pro−Aminoluciferin)を加水分解して、アミノルシフェリン(Aminoluciferin)を生成可能であり、該物質はDPPIV−Glo(TM)プロテアーゼ検出キットにより提供されるルシフェラーゼ反応系において、「グローライク型」の発光信号を発生することが可能であり、該発光信号の強弱はDPP−IV酵素の活力と正比例をなす。
本発明の化合物I−1〜I−4の、ジペプチジルペプチダーゼIV(DPP−IV)酵素の活性に対する阻害を観察して、その阻害効果を評価する。
2.1 ヒト由来の組み換えジペプチジルペプチダーゼIV(DPP−IV):SIGMA製品、カタログ番号D3446−10UG。
2.2 DPPIV−Glo(TM)プロテアーゼ検出キット:Promega製品、カタログ番号G8351。
2.3 Trizma base:Sigma製品、カタログ番号T6066−1KG:10mM Tris−HCl、pH 8.0に調製した。
2.4 384孔板(OptiPlate):PerkinElmer製品、カタログ番号6007299。
2.5 液体処理装置:Bravo(Agilent社);Echo(Labcyte社)。
2.6 検出装置:Envision(PerkinElmer社)。
3.1 Bravoを用いて、DMSOを用いてテストサンプルを10種類の濃度に勾配希釈してから、Echoを用いて250nlのサンプルを384孔板に移動した。
3.2 10mMのTris−HCl(pH 8.0)を用いて、ジペプチジルペプチダーゼIV(Sigma)を0.2ng/mlの溶液に希釈し、テストサンプルに入れ、孔当たり25μlであった。同時に、ブランクコントロール(基質を含むが、酵素とサンプルは含まない)及びポジティブコントロール(基質、酵素を含むが、サンプルは含まない)を設けた。
3.3 孔当たりに25μlのDPPIV−GloTMReagentを加入した(DPPIV−Glo(TM)プロテアーゼ検出キットの説明書に従って調製し、20μMのDPP−IV基質Gly−Pro−アミノルシフェリン及びルシフェラーゼ反応系を含む)。
3.4 室温で60min反応させ、Envisionを用いて発光強度を測定した。
3.5 発光強度に基づいて、DPP−IV酵素の活力を算出し、酵素の活力=(サンプルの発光強度値−ブランクコントロールの発光強度値/(ポジティブコントロールの発光強度値−ブランクコントロールの発光強度値)×100であった。
3.6 酵素の活力に基づいて、GraphPad Prism5.0ソフトウェアを用いて、サンプルのIC50を算出した。
本発明の化合物I−3(以下、TSL−0319と略称する)のジペプチジルペプチダーゼ酵素の活性に対する阻害作用を観察し、既に市販されている同種類の薬物の選択性と比較する。
2.1 ヒト由来の組み換えジペプチジルペプチダーゼIV(DPP−IV)、DPP8、およびDPP9酵素以外、他の実験材料は試験例(一)と同じであった。
OGTT(経口耐糖能実験)実験過程:試験を開始する前に、6時間断食させ、投薬後60minに胃内投与によってグルコース(薬物濃度0.6mg/ml、投薬体積5ml/kg)(糖尿病マウスに2g/kgで糖を投与、肥満マウスに2g/kgで糖を投与、正常マウスに5g/kgで糖を投与)を供与し、それぞれグルコース供与後0min、15min、30min、45min、60min、120minの血糖値を測定した。
正常マウスの耐糖能実験は表3、図1〜図2に示されており、本発明の化合物I−3(TSL−0319と略称)は良好な血糖降下効果を有し、特に、血糖降下効果はリナグリプチンより優れている。
肥満マウスの耐糖能実験は、表4、図3〜図4に示されており、本発明の化合物I−3(TSL−0319と略称)は良好な血糖降下効果を有し、特に、血糖降下効果はリナグリプチンより優れている。
糖尿病マウスの耐糖能実験、表5、図5〜図6に示されており、本発明の化合物I−3(TSL−0319と略称)は良好な血糖降下効果を有し、特に、血糖降下効果はリナグリプチンより優れている。
体内の糖代謝試験において、正常マウス、肥満マウス、糖尿病マウスを利用して研究を行った。本発明の化合物I−3(TSL−0319と略称)は、3種類のマウスに対して、いずれも血糖降下作用を有し、かつ血糖降下効果がリナグリプチンより優れている。
体外のヒト肝ミクロソームのインキュベーションシステムを用い、cocktailプローブ薬物法(公開技術)によって、同時にヒト肝ミクロソームのCYP1A2、CYP2C9、CYP2C19、CYP2D6、CYP3A4基質フェナセチン、ジクロフェナク、S−メフェニトイン、デキストロメトルファン、ミダゾラムの含有量の変化を測定し、異なる濃度下で、TSL−0319のヒト肝ミクロソームのCYP1A2、CYP2C9、CYP2C19、CYP2D6、CYP3A4ハプロタイプ活性に対する影響を評価し、かつ対応するIC50を測定した。
TSL−0319のCYP1A2、CYP2C9、CYP2C19、CYP2D6、CYP3A4の5種類の代謝酵素に対するIC50は、いずれも50μMより大きいため、TSL−0319の使用は他の薬物の代謝に影響を及ぼすことがなく、他の薬物の併用可能である。
7−10週齢の健康なCD−1マウス6匹をランダムに2組に分けた。それぞれ静脈注射及び胃内投与によって2mg/kg、5mg/kgのTSL−0319(静脈注射、2mg/ml、DMSO/PEG400/H2O=20/60/20の溶液で透明な溶液に作製し、胃内投与、5mg/ml、PEG400/Tween80/H2O=40/10/50の溶液で透明な溶液に作製する)を供与し、投薬する前に12時間断食させ、自由に水を飲用させ、投薬する前及び投薬後に、時点に従って、大伏在静脈または顎下静脈から採血し(静脈注射の採血時点:0h、0.0833h、0.250h、0.500h、1.00h、2.00h、4.00h、8.00h、12.00h、24.00h;胃内投与の採血時点:0h、0.250h、0.500h、1.00h、2.00h、4.00h、8.00h、12.00h、24.00h)、最低定量の濃度(lower limit of quantitation,LLOQ)は3ng/mlとした。
TSL−0319はCD−1マウスを利用して薬物動態学実験を行い、採血時点及びLLOQの設定によって、そのT1/2はlinagliptinの開示データに比べ、大きな差異があるが、60.5%のバイオアベイラビリティは、同等な条件下のlinagliptinのバイオアベイラビリティ(linagliptinはCD−1マウスを利用して薬物動態学実験を行い、5mg/kg、経口であり、バイオアベイラビリティは18.4%である)より顕著に高い。
本発明の化合物I−1〜I−2、1−4の構造はI−3に類似するため、化合物I−1〜I−2、1−4は、いずれも化合物I−3と同じ薬効、作用を有する。
