Description
本発明は化学修飾蛋白質の実質的に均質な製剤およびそのための方法に関する。本明細書における「実質的に均質な」とは、観察される化学修飾された蛋白質のみが1つの「修飾物質」(例えばDTPA、EDTA2、スクシニル)部分を有するものであることを意味する。製剤は未反応(即ち修飾物質部分を欠く)蛋白質を含有してもよい。ペプチドマッピングおよびN−末端配列決定により確認されるとおり、以下に示す1つの例は少なくとも90%が修飾蛋白質であり最大10%が非修飾蛋白質である製剤を与えるものである。好ましくは、化学修飾物質は製剤の少なくとも95%(以下の製造実施例に示すとおり)であり、そして好ましくは化学修飾物質は製剤の99%以上である。化学修飾物質は生物活性を有する。本明細書において示す本発明の「実質的に均質な」モノスクシニル化蛋白質、DTPA−レプチン、および、EDTA2−レプチンの製剤は、均質な製剤の利点、例えば、ロット毎の薬物動態が予測可能な臨床的用での容易性を示すために十分均質なものである。
本発明の蛋白質スクシニル化方法は一般的に以下の通り説明できる。
本発明のDTPA修飾法は一般的に以下の通り説明できる。
本発明のEDTA2修飾法は一般的に以下の通り説明できる。
