一方、近年、生体試料中に含まれる薬剤(薬物)検査のニーズが高まっている。特にスポーツの世界におけるドーピング検査は種々の薬物を検査する必要があり、且つそれが微量であっても検出ミスがないようにする必要がある。通常、このような薬物検査は、前処理カラムを使用して固相抽出し、得られた抽出液をさらに高速液体クロマトグラフィーやガスクロマトグラフィーを用いて分析・検出することによりなされる。しかしながら、上記のように薬物検査は、種々の薬物を対象にして行われるため、塩基性、中性或いは酸性の化合物の何れであっても吸着することができる前処理カラムの開発が望まれていた。一方、特表2002-51574等には、そのような吸着対象の広いカラム(充填剤)として、イオン交換基、疎水性成分及び親水性極性成分を有する多孔質樹脂化合物が記載されている。しかしながら、このような化合物であっても上述したような対象成分全てを効率よく吸着することはできておらず、更なる改良が求められていた。
とを重合して得られるポリマーのグリシジル基に、陰イオン交換基を導入して得られるポリマー、(2)該ポリマーを含んでなる、末端に酸性基を有するパーフルオロ化合物測定用充填剤、(3)該充填剤を充填した、末端に酸性基を有するパーフルオロ化合物測定用前処理カラム、(4)該カラムを用いることを特徴とする末端に酸性基を有するパーフルオロ化合物の測定方法、(5)上記ポリマーを含んでなる薬物測定用充填剤、(6)該充填剤を充填した薬物測定用前処理カラム、(7)該カラムを用いることを特徴とする薬物の測定方法に関する。
また、一方で本発明のポリマーを含んでなる充填剤は、従来の対象範囲の広い前処理カラム用充填剤と比較して、塩基性、中性又は/及び酸性化合物等の対象物を同等又はそれ以上効率よく吸着することを可能とする。そのため、1回の前処理で複数の対象物を同時に効率よく濃縮分離することが可能となる。特に対象物を薬物とした場合、より効率よく吸着し得るため、薬物測定用の前処理カラムとして非常に有用なものである。更にまた、吸着した塩基性、中性又は/及び酸性化合物については、塩基性・中性化合物と酸性化合物とを別々に溶出することも可能となるため、対象物が多数の場合、分離分析を容易にするという効果も奏する。
(式中、R3は、それぞれ独立して炭素数1~3の直鎖アルキル基を、R4は、炭素数1~6の直鎖アルキル基を表す)で示される基が挙げられる。該陰イオン交換基は、ポリマーを酸性基結合パーフルオロ化合物測定用充填剤として用いる場合、3級アミノ基が好ましく、ポリマーを薬物測定用充填剤として用いる場合、4級アンモニウム基が好ましい。
上記2級アミノ基の好ましい具体例としては、例えば、メチルアミノ基、エチルアミノ基、n-プロピルアミノ基等が挙げられる。
(式中、R1、R2、R3、R4、R9、R10、R11、R12、R15及びR16は上記の通り。)で示される。該ポリマーは、薬物測定用充填剤として好ましい。該一般式[6]の具体例としては例えば、
次いで、(2)カラムに吸着された薬物を溶出液で溶出する場合、中性及び塩基性の薬物については、メタノール、エタノール、プロパノール、アセトニトリル、アセトン、ジクロロメタン等の水溶性有機溶媒により溶出し、酸性の薬物については、通常pH1~3、好ましい範囲はpH1~2の、酸性水溶液又は酸性に調整した、メタノール、エタノール、プロパノール、アセトニトリル、アセトン、ジクロロメタン等の水溶性有機溶媒等により溶出する。該酸性水溶液又は酸性水溶性有機溶媒のpHの調整は、通常この分野で用いられている酸性化合物を用いた方法により行えば特に限定されないが、該酸性性化合物としては例えば塩酸、硝酸、酢酸、ギ酸等が好ましいものとして挙げられる。具体的な調製方法としては、例えばギ酸を用いてpHを1~2に調整する場合、溶出液中の濃度として通常1~5w/w%、好ましい範囲としては1~2w/w%ギ酸を含むように酸性水溶液又は酸性水溶性有機溶媒を調製すればよい。上記(2)の溶出における溶出液の用量は、充填剤の量に応じて適宜設定すればよく、充填剤10mgに対して通常0.3~100mL、好ましい範囲は0.3~10mL、より好ましい範囲は0.3~1mLである。
更に、(3)溶出された薬物含有溶出液を自体公知の分離測定法で測定することにより、試料中の薬物の量又は濃度が得られるが、分離測定に用いられる薬物含有溶出液は、必要に応じて、自体公知の方法により濃縮した後、分離測定法に供してもかまわない。分離測定方法としては、例えば液体クロマトグラフィー法やガスクロマトグラフィー、電気泳動法等が挙げられ、測定は、自体公知のUV検出、蛍光検出、MS、MS/MS、蒸発光散乱検出(ELSD)等を用いればよく、条件等も通常この分野でなされているものに準じて設定されればよい。
疎水性モノマーとしてジビニルベンゼン(新日鐵化学(株)製) (純度80%) 85.0g(純ジビニルベンゼンを0.52mol含有)、極性モノマー(イオン交換基の導入が可能なモノマー)としてグリシジルメタクリレート(和光純薬工業(株)社製)15.0g(0.106mol)を用い、水に不溶な有機溶媒としてトルエン100gを用いた。上記2種のモノマーと水に不溶な有機溶媒との混合溶媒に、重合開始剤としてアゾビスイソブチロニトリル(和光純薬工業(株)社製)1.0gを添加して溶解した後、0.2重量%のメチルセルロース水溶液0.8L中に懸濁させ、高速攪拌を行い油滴の平均粒径が約60μmになるように調整した。その後、攪拌装置の付いた重合装置に移し、80℃で6時間反応させて、架橋性多孔質共重合体粒子を得た。この粒子をろ過した後、水2L、メタノール2Lで洗浄し、酢酸エチルに1晩浸漬した。その後、メタノール2Lで洗浄し、乾燥させた。このようにして得られた架橋性多孔質共重合体粒子は、平均細孔径10.26nm、比表面積636m2/gであった。この粒子を32μm及び63μmの篩を用いて分級した。

一方、本発明のポリマー3及び4と一部類似構造を有する比較ポリマー1については、中性化合物、塩基性化合物何れも低い回収率を示した。同様に、本発明のポリマー3及び4と一部類似構造を有する比較ポリマー2についても、テオフィリンやスコポラミン臭化水素について低い回収率を示した。中性及び塩基性化合物の保持能力は、ポリマー骨格の構造による影響が大きいと推測される。従って、本発明のポリマー3及び4のような、ジビニルベンゼンとグリシジルメタクリレートからなるポリマー構造やジビニルベンゼン、イソシアヌル酸トリアリル及びグリシジルメタクリレートからなるポリマー構造が、中性及び塩基性化合物の高い保持能力に寄与していると考えられた。
酸性化合物である、サリチル酸及びナプロキセンは、メタノールでは溶出できなかったが、表7の結果から明らかなように、2%ギ酸を含むメタノールで溶出し得、その結果によれば、本発明のポリマー3及び4は、Oasis MAXとほぼ同等の回収率であることが判った。比較ポリマー2は、サリチル酸及びナプロキセン共に70%弱の回収率であり、低い値を示した。酸性化合物の保持能は主に陰イオン交換基により左右されると推測されたが、この結果によれば、同じイオン交換基(エチルジメチルアンモニウム基)を有していても、基本のポリマー骨格が異なると酸性化合物の保持能も変化することが判った。従って、本発明のポリマー3及び4の如きポリマーに陰イオン交換基を導入することにより、中性、塩基性化合物の優れた保持能のみでなく、優れた酸性化合物の保持能も有することが明らかとなった。
