DMSO-d6:重ジメチルスルホキシド
1-(3-(2-(1-ベンゾチオフェン-5-イル)エトキシ)プロピル)アゼチジン-3-オール・マレイン酸塩7.00gの水35mLおよび酢酸エチル35mL混液に氷冷下、5mol/L水酸化ナトリウム水溶液を加え、pH11.7に調整した。有機層を分取し、水および飽和食塩水で順次洗浄後、無水硫酸マグネシウムで乾燥し、減圧下で溶媒を留去した。得られた残留物に塩化メチレン25mLを加え、6~7℃でトリフルオロ酢酸6.62mLを滴下した。ついで、4~7℃でm-クロロ過安息香酸3.65gを分割添加し、同温度で2時間攪拌した。不溶物を濾去後、残渣を水で洗浄した。濾液および洗液を合わせ、水層を分取した。有機層を水で抽出し、合わせた水層を酢酸エチルで洗浄後、酢酸エチルを加え、炭酸カリウムでpH10.5に調整した。水層を分取し、クロロホルムで抽出後、無水硫酸マグネシウムで乾燥し、減圧下で16.1gまで濃縮した。
得られた溶液に氷冷下、マレイン酸1.20gのメタノール4.5mL溶液を滴下し、ついで酢酸エチル13.5mLを滴下し、同温度で1時間攪拌した。固形物を濾取し、1-(3-(2-(1-ベンゾチオフェン-5-イル)エトキシ)プロピル)アゼチジン-3-オール S-オキシド・マレイン酸塩3.36gを得た。
1H-NMR(DMSO-d6)δ値:1.74-1.63(m,2H),2.91(t,2H,J=6.5Hz),3.11(t,2H,J=7.6Hz),3.42(t,2H,J=5.9Hz),3.63(t,2H,J=6.5Hz),3.82-3.73(m,2H),4.28-4.15(m,2H),4.51-4.41(m,1H),6.03(s,2H),6.14-6.09(m,1H),7.43-7.38(m,1H),7.43(d,1H,J=6.1Hz),7.46(d,1H,J=6.1Hz),7.57-7.53(m,1H),7.90(d,1H,J=7.6Hz)
化合物A投与液は、化合物A・マレイン酸塩を生理食塩液に溶解し、化合物A・マレイン酸塩濃度を14mg/mLに調整した。化合物Aオキシド投与液は、化合物Aオキシド・マレイン酸塩を生理食塩液に溶解し、化合物Aオキシド・マレイン酸塩濃度を14.54mg/mLに調整した。
各々の投与液を非絶食下、ラット(Crl:CD系雄性ラット、8週齢)に経口投与した。投与量は、化合物A投与群で56mg/kg、化合物Aオキシド投与群で58mg/kgとした。
投与から0.25、0.5、1、2、5、8、10および12時間後、各群についてエーテル軽麻酔下で腹部大動脈より全血をヘパリン加採血した後、放血致死させ、脳を摘出した。
採取した血液を約1600×g、4℃、10分間遠心分離して血漿を得た。得られた血漿100μLに内標準物質25ng/mLを含む蒸留水900μLおよびリン酸25μLを加えて攪拌した後、メタノールおよび蒸留水でコンディショニングした固相抽出プレート(Oasis HLB 10mgまたは30mg、Waters社製)に添加した。蒸留水2mLで固相抽出プレートを洗浄した後、アセトニトリル2mLで溶出した。溶出液を濃縮乾固した後、移動相A液に溶解し、約1600×g、4℃、10分間遠心分離した。得られた上清を液体クロマトグラフ-タンデム質量分析計に付し、各群の血漿中の化合物A濃度を求めた。
摘出した脳を25%アンモニア水/メタノール(1:49)(脳湿重量の10倍容量)でホモジナイズした後、ホモジネート2mLを約1600×g、4℃、10分間遠心分離して上清を分取した。沈渣に25%アンモニア水/メタノール(1:49)2mLを加え、約1600×g、4℃、10分間遠心分離して上清を分取した。これら上清を合わせて濃縮乾固した後、内標準物質25ng/mLを含む蒸留水1mLに溶解した。得られた溶液にリン酸25μLを加えて攪拌した後、上記の血漿と同様の固相抽出操作を行った。得られた溶出液を濃縮乾固した後、移動相A液または50%メタノールに溶解し、約1600×g、4℃、10分間遠心分離操作した。得られた上清を液体クロマトグラフ-タンデム質量分析計に付し、各群の脳内の化合物A濃度を求めた。
