本発明に係る前記化合物Iは、アストロサイト分化促進活性を有するため、前記化合物Iを含有する組成物は、神経変性疾患、脳血管障害及び精神疾患の予防又は治療のための、神経細胞の外科的損傷に対する予防、回復及び再生の促進のための、並びに、糖尿病性神経障害の予防又は治療のための医薬組成物として使用できる。
本発明に係る前記化合物Iは、アストロサイト分化促進活性を有するため、前記化合物Iを含有する組成物は、神経変性疾患、脳血管障害及び精神疾患の予防又は治療のための、神経細胞の外科的損傷に対する予防、回復及び再生の促進のための、並びに、糖尿病性神経障害の予防、並びに健康の維持又は増進のための食品組成物として使用できる。
ウコンは、沖縄長生薬草本社(沖縄県)製「春ウコン100%健康SAISEI」を活性成分の抽出に使用した。実験に使用した試薬は、下記の説明中に記載した。また、実験に使用した溶媒は、特に明記しない限り、市販の上級グレードのものを使用した。
市販の春ウコンを用い図1に記載のスキームで分画、及び単離精製した。各ステップで下記神経分化調節活性試験を行い、アストロサイトへの分化促進活性を指標に、活性成分を同定した。
上記ウコンからの抽出分画及び単離精製化合物の活性評価に使用した神経分化調節試験は、神経幹細胞(NSC)を用いて免疫蛍光法により特許文献1に記載の方法と同様の方法で評価した。評価に当たって、統計解析は、Microsoft Excel(Microsoft Corporation、米国)を使用し、ad-hoc検定で、Bonferroniの方法で多重性を補正したt検定法(両側検定、対応なしの等分散)を使用して有意差を検定した。有意水準はp<0.05とした。
図1のスキームに記載された方法で分画された画分3-7、画分6-5(コロナリンD)及び画分6-7(コロナリンC)の共存下、NSCを培養し、Hoechst33342による核染色、抗GFAP抗体によるGFAP染色を行って得られた蛍光顕微鏡写真の代表例を図4に示した。
