実験動物としてICRマウスを用いて本発明化合物の急性毒性試験を行った。
1)実験方法
ICRマウスを用い、式IIIに示す化合物(15d(図2))を溶媒(PEG: 生理食塩水=50:50)に溶かしたものを20mL/kg(10 mg/kg 又は100 mg/kg)4日間連続で投与し、7日間の体重変化を測定した。
2)実験結果
100 mg/kgの化合物を投与した群(4匹)は,4匹共に投与の翌日から体重の減少が認められ、投与後5日目から7日目で投与群の全てのマウスが死亡した(5日目で1匹死亡、6日目で2匹死亡、7日目1匹死亡)。一方、10 mg/kgの化合物を投与した群(4匹)においては、投与の翌日から体重のわずかな減少が認められたが、投与後5日目辺りから4匹とも体重の回復が認められ、7日目までで死亡したマウスはなかった。
実験動物として、Wistar系雄性ラット(4匹)を用いて本発明化合物の消化管吸収評価実験を行った。
1)実験方法
in situ小腸吸収実験法に準じた。
ペントバルビタール麻酔下のラットを開腹して、小腸(全長)のループを作製し、ループ内に既知量の式IIIに示す化合物(15d(図2))(溶媒(PEG: 生理食塩水=50:50)に溶かしたもの)を1mg/1mL(試料液)で投与した。1時間後に小腸ループ内を洗浄し、洗浄液を全量生食で回収し10mLとした。回収した洗浄液中の化合物を定量し、投与量との差を吸収量とみなした。試料液は1mg/1mLで消化管内に投与して1時間後に残存液を10mLの生理食塩液で回収した。すなわち回収液は0.1mg/mLとなる。回収液に不純物が混じっているため1500rpmで10分遠心分離を行った後、上澄をクロロホルムで抽出し、溶媒を減圧留去後、残渣をメタノール10mLに溶かした。これを分光光度計を用いて定量を行った(測定波長は340 nm)。
2)実験結果
消化管吸収率は76.6%±1.2(average±S.D, n = 4)であった。
