Abstract
Description
本出願は、1999年1月5日に発行された米国特許第5,856,535号および2008年9月8日に出願された米国特許出願公開番号2010−0324004に関連する。両文献は、引用によりその全体を本明細書中に包含される。
本発明は、糖尿病のようなタンパク質チロシンホスファターゼ1B(PTP1B)関連疾患の処置のための、哺乳動物における酵素PTP1Bの選択的阻害のためのアミノステロイド化合物の使用に関する。
タンパク質リン酸化は、細胞機能の種々の段階にてシグナルを伝達および調節するための細胞機構としてよく認識されている(例えば、Hunter, Phil, Trans. R. Soc. Lond. B. 353: 583-605 (1998); Chan et al., Annu. Rev. Immunol. 12: 555-592 (1994); Zhang, Curr. Top. Cell. Reg. 35: 21-68 (1997); Matozaki and Kasuga, Cell. Signal. 8: 113-119 (1996)を参照のこと)。少なくとも2種の主要なホスファターゼクラスが認識されている:(1)セリンまたはスレオニン部分上にリン酸基を含むタンパク質を脱リン酸化するもの(Ser/Thrホスファターゼまたは二重特異性ホスファターゼ(DSP)と呼ばれる)、および(2)アミノ酸チロシンからリン酸基を除去するもの(タンパク質チロシンホスファターゼ(PTPaseまたはPTP)と呼ばれる)。
本発明は、タンパク質ホスファターゼIB(PTPIB)を阻害する種々のアミノステロイド化合物に関する。本発明はまた、これらのアミノステロイド化合物を含む組成物、例えば薬学的に許容される組成物など、および哺乳動物、特にヒトにおけるPTP1B関連疾患を処置するためのそれらの使用方法に関する。

実施例1−アミノステロイド類縁体によるPTP1Bの阻害
アミノステロイド類縁体を、市販されている完全長チロシンホスファターゼPTP1Bに対する阻害について試験した。各類縁体のPTP1B活性の阻害能を、5μMのアミノステロイド類縁体の存在下で測定した。アッセイには、ホスファターゼ活性を評価する非特異的基質であるパラ−ニトロ−フェニルホスフェート(pNPP)を用いる。ホスファターゼ活性は、PTP1BがpNPPをp−ニトロフェノール(pNP)に加水分解する触媒能に基づいた。活性は、吸光度405nm(色原体、パラ−ニトロフェノール(pNP)の吸光度)での単一点を用いて測定した。アミノステロイド類縁体によるチロシンホスファターゼ活性の%阻害は、阻害剤不存在下で観察されるpNP形成の最大反応と比較して、阻害剤存在下でのpNP形成の部分反応により決定された。これらのアッセイの結果を表1に示し、多くの類縁体が、5μM濃度で50%を超える阻害をもたらすことが示される。
アミノステロイド類縁体はまた、免疫反応の阻害によるそれらの潜在毒性を示すチロシンホスファターゼTCPTPの阻害能についても試験した。TCPTP阻害アッセイを、完全長TCPTPを200μM濃度で酵素および阻害剤として用いること以外、PTP1Bアッセイと同様の方法で行った。TCPTP阻害アッセイの結果を表1、カラム4に示し、3つの化合物が、20倍以上の濃度でさえ、50%未満のTCPTP阻害を示す。
アミノステロイド類縁体のインビボ効果を決定するために、ob/ob(Lepob)マウスモデルを用いた。Ob/obマウスは、抗糖尿病薬および/または抗肥満薬のスクリーニングのために広く使用されている。Ob/obマウスを、食塩水または5もしくは10mg/kgのアミノステロイド類縁体の何れかを、3日毎に計4回の腹腔内投与により処理した。体重、耐糖能および空腹時血中グルコース濃度を、実験中に各群について測定した。各群には、少なくとも4匹の動物がいた。全ての反応材および実験動物は、市販されている。
