1.実験用の医薬品および試薬:
実施例4〜9で調製した化合物I−1、I−2、およびI−3、化合物I−1の塩酸塩、化合物I−2のタウリン酸塩、ならびに化合物I−3の硫酸塩を使用する。
ADP:シグマ社(SIGMA Co.)により製造されたもの
カルボキシメチルセルロースナトリウム800−1200:シノファーム化学薬品社(Sinopharm Chemical Reagent Co., Ltd.)、バッチ番号:F20051103。
ウィスター系ラット:中国医学科学院実験動物研究所(The Institute of Laboratory Animal Science、Chinese Academy of Medical Sciences)、ライセンス番号SCXK(京)2005−0013により提供された、SPFグレードの雄。
PAM−3 2チャンネル血小板凝集装置(Dual Channel Platelet Aggregometer):江蘇省丹陽無線電廣(Jiangsu Danyang Radio Factory)により製造されたもの。
200〜250gの体重の健常な雄のウィスター系ラットを選択し、無作為にグループ分けした。本実験は3つのバッチで行い、各バッチに正常な対照グループと6種類の化合物のグループとを割り振り、全体として2種類の用量のグループを各バッチにおいて試験した。化合物I−1、I−2、およびI−3、化合物I−1の塩酸塩、化合物I−2のタウリン酸塩、ならびに化合物I−3の硫酸塩についての2種類の用量のグループの設定は、それぞれ15mg/kg、30mg/kgとした。10ml/kgbwの用量体積での胃内投与を使用した。正常な対照グループには、同量の0.5%のCMC−Naを投与した。投与の2時間後、40mg/kgのペンタバルビタールナトリウムを麻酔のために腹腔内投与し(1ml/kg)、腹大動脈から採血した。3.8%のクエン酸ナトリウムを抗凝固に使用し、多血小板血漿(PRP)と血小板乏血漿(PPP)とをそれぞれ調製した。ADP(最終濃度:1.08μM)が誘導した血小板の凝集の最大パーセンテージを、PAM−3 Dual Channel Platelet Aggregometerで試験した。
ラットへの胃内投与の実験の際の予備研究の結果は、本発明の化合物I−1、I−2、およびI−3、化合物I−1の塩酸塩、化合物I−2のタウリン酸塩、ならびに化合物I−3の硫酸塩と、市販の医薬品であるクロピドグレルとが全てプロドラッグであり、これらが治療効果を達成するには、関連する酵素の作用下にインビボで活性な代謝物であるチオールに変換される必要があることを示している。しかし、化合物I−1、I−2、およびI−3、化合物I−1の塩酸塩、化合物I−2のタウリン酸塩、ならびに化合物I−3の硫酸塩の変換率はクロピドグレルよりも約5倍高く、それらの活性な代謝物のピーク濃度までの時間は50分から1時間であり、これもまたクロピドグレルよりも早い。したがって、本発明の化合物は、より早く作用を開始する抗血小板薬へとさらに発展する可能性がある。
材料および方法:
試験用化合物:化合物I−1およびクロピドグレル。
溶液の調製:化合物I−1を0.5%のCMC−Naおよびトウモロコシ油とともにすりつぶし、次に超音波条件下で溶解させる。100mg/mlの懸濁液を使用前に調製し、1ml/100gで毎朝、胃内投与する。
実験用動物:約180gの体重のSDラット。各グループに7匹の雌および7匹の雄。
グループ分けおよび用法:化合物I−1を、2週間の間、1000mg/kgの用量を1日に1回胃内投与する。同量の溶媒をブランク対照グループに胃内投与し、等用量(1000mg/kg)のクロピドグレルをポジティブ対照グループに胃内投与する。
ラットの死亡は、試験期間全体の間に医薬品を投与したグループ全てにおいて起こり、死亡の具体的な数および時間を表3に示す。胃内投与の3日目から、ラットの鼻の周囲に出血性の分泌物を、化合物I−1グループおよびクロピドレルのグループの両方で観察することができたが、これは、クロピドグレルのグループに比べて化合物I−1のグループにおいては明らかに僅かである。
