GK活性は酵素反応により生成するグルコース6リン酸を直接測定するのではなく、グルコース−6−デヒドロゲナーゼによる共役反応によって生成するNADH量を測定することによって調べた。
ヒト肝臓型、膵臓型GKのクローニング及び組換え蛋白の取得
GeneBank上に登録されているヒト肝臓型GKの配列Accession Number;NM_033507、ヒト膵臓型GKの配列Accession Number;NM_000162を参考にして、それぞれヒト肝臓cDNA(Clontech社製)、ヒト膵臓cDNA(Clontech社製)を鋳型としてPyrobest DNA Polymerase(TaKaRa社製)によりPCRクローニングを行った。さらにC末端側に(His)6標識してHisタグ融合蛋白として大腸菌内で可溶性画分に発現させた。菌体を超音波破砕したのち、遠心分離を行い上清を回収した。回収した上清を金属キレートアフィニティークロマトグラフィーで精製した。
アッセイはCostar製の平底の2分の1エリア96穴プレートを用いて25℃で行った。インキュベーション混合液は、最終的に25mM HEPES緩衝液(pH7.1)(Invitrogen社製)、25mM KCl(和光純薬製)、2mM MgCl2(和光純薬製)、5mMD−グルコース(和光純薬製)、1mM ATP(Roche社製)、1mM NAD(Sigma製)、1mMジチオスレイトール(和光純薬製)、5Unit/mL G6PDH(Sigma製)、0.1% BSA(Sigma社製)試験化合物或いは5%DMSO及びGKが含まれるように調製した。
ICRマウス(雄性、7−9週齢;日本チャールズリバー社)を使用し、被験化合物による血糖値への作用を測定した。各々の化合物をGelucire44/14(商品名、Gatefosse社製):PEG400=60:40の混合液に溶解させ、餌を2時間抜いたマウスに経口投与(30mg/kg、10mL/kg)した。投与直前(Pre値)および投与後0.5、2および4時間のポイントで尾静脈よりエチレンジアミン四酢酸2カリウムをコーティングした採血管で採血し、遠心分離(4℃、3,600×g、3分間)して血漿サンプルを得た。
5分間静置して発色させた。測定はEn Vision 2103 Multilabel Reader(商品名、PerkinElmer社製)を使用しOD505nmで測定した。各採血ポイントのPre値に対するグルコース低下率からΣグルコース低下率(各採血ポイントのPre値に対するグルコース低下率の平均)を算出した。
発明化合物1〜6、8、13、15、18、21〜23、28、31、34、35、51、64、65は、35%以上のΣグルコース低下率が認められた。
参考例3にて製造した(+)−2−(4−(シクロプロピルスルホニル)フェニル)−3−[(1α,3α,4α)−3,4−ジフルオロシクロペンチル]−N−(チアゾール−2−イル)プロピオン酸アミド、参考例8にて製造した(−)−2−(4−(シクロプロピルスルホニル)フェニル)−3−[(1β,3α,4α)−3,4−ジフルオロシクロペンチル]−N−(チアゾール−2−イル)プロピオン酸アミド、(+)−2−(4−(シクロプロピルスルホニル)フェニル)−3−[(1β,3α,4α)−3,4−ジフルオロシクロペンチル]−N−(チアゾール−2−イル)プロピオン酸アミドには、20%を超えるΣグルコース低下率を示すものはなかった。
