Diabetes Federation(IDF)によると、2012年の世界の糖尿病患者は3億7100万人以上であり、適切な糖尿病対策が取られなければ、2030年には5億5200万人に増加するとされている。
近年、インスリン分泌応答が低下するため、食後に血糖値が大きく上昇してしまう、食後過血糖が注目されている。食後過血糖は、高血圧、心筋梗塞、脳梗塞などを引き起す要因となる。これは高血糖を維持したものより発生率が高くなる。
食後過血糖の改善を目的として、例えば、血糖上昇抑制作用を持つセキステルペンラクトン(特許文献1)、オキサジアゾリジンジオン化合物(特許文献2)、ペプチド(特許文献3)、トリテルペンアルコール(特許文献4)などが報告されている。
塩基性基における塩としては、例えば、塩酸、臭化水素酸および硫酸などの鉱酸との塩;ギ酸、酢酸、クエン酸、シュウ酸、フマル酸、マレイン酸、リンゴ酸、酒石酸、アスパラギン酸、トリクロロ酢酸およびトリフルオロ酢酸などの有機カルボン酸との塩;並びにメタンスルホン酸、ベンゼンスルホン酸、p−トルエンスルホン酸、メシチレンスルホン酸およびナフタレンスルホン酸などのスルホン酸との塩を、また、酸性基における塩としては、例えば、ナトリウムおよびカリウムなどのアルカリ金属との塩;カルシウムおよびマグネシウムなどのアルカリ土類金属との塩;アンモニウム塩;並びにトリメチルアミン、トリエチルアミン、トリブチルアミン、ピリジン、N,N−ジメチルアニリン、N−メチルピペリジン、N−メチルモルホリン、ジエチルアミン、ジシクロヘキシルアミン、プロカイン、ジベンジルアミン、N−ベンジル−β−フェネチルアミン、1−エフェナミンおよびN,N−ジベンジルエチレンジアミンなどの含窒素有機塩基との塩などを挙げることができる。
一般式(1)および(1b)の塩としては、の上記した塩の中で、薬理学的に許容される塩が好ましい。
この反応は、イミノ基にハロゲノ化合物を用いて置換基を導入する公知ものであり、使用される溶媒や塩基等は、適宜選択すればよい。
この反応は、公知の反応に準じて行えばよいが、例えば、酢酸-塩酸溶液中で、加熱還流を行えばよい。
この反応は、公知の反応に準じて行えばよいが、例えば、テトラヒドロフラン中で、加熱還流を行えばよい。
この反応は、公知の反応に準じて行えばよいが、例えば、塩化メチレン中、室温で撹拌すればよい。
ブロミドとカリウム tert-ブトキシドを用いたオレフィン化反応に付すことにより一般式(1a_4)の化合物を製造することができる。
この反応は、公知の反応に準じて行えばよいが、例えば、テトラヒドロフラン中、室温で撹拌すればよい。
この反応は、公知の反応に準じて行えばよいが、例えば、酢酸エチル中など溶媒中で行えばよい。
この反応は、公知の反応に準じて行えばよいが、例えば、二塩化エチレン中で、加熱還流を行えばよい。
このようにして得られた目的の化合物は、抽出、晶出、蒸留およびカラムクロマトグラフィーなどの通常の方法によって単離精製することができる。
・食後過血糖に及ぼす効果

SLC, Inc.より購入、平均体重 (22g)を用い、薬物を投与しないコントロール群、被検物を100mg/kg体重となるように投与した群に分けた(各群5匹)。薬物は胃ゾンテにて経口投与し、薬物投与と同時にグルコース溶液を、それぞれ2.5g/kg体重となるように胃ゾンテにて経口投与し、投与開始から15、30、60及び120分に尾静脈から採血をおこない、血糖値を測定した。血糖値の測定はStatStrip Xpress (Nova Biochemical社製)にて測定した。
結果を表1に示す。なお、表中の数値は、コントロール群を100とした場合の百分率である。
