(発明の分野)
本発明は、脳機能を改善できるトリテルペン(triterpene)化合物に関し、更に詳しくは、減退した記憶力改善のため化学式(1)で表されるトリテルペン化合物の新しい使用
と、化学式(1)で表されるトリテルペン化合物を含有する脳機能改善のための薬剤組成物に関する。
世界中で人口における老人の割合が増加するにつれ、種々の老人退行性疾患及び障害が、社会及び経済の両観点から大きな損失を引き起こすことにより、社会の注目を大いに集めてきた。アメリカ痴呆協会(American Dementia Assocciation)及び国立老化研究所(National Aging Research Institute)の統計調査の最近の結果によると、400万人のアメリカ人が痴呆を患っており、それは一般的に60歳を過ぎて発病するが、ときには50代でも発病する。65歳以上のアメリカ人の10.3%が痴呆であるとの診断を受け、米国における年間の痴呆の治療費用は950億USドルに達する。
R1、R2及びR4は各々CH3基であり、R3はHである;または
R1及びR2は各々CH3基、R3はHであり、R4はCH2OHである;または
R1、R3及びR4は各々CH3基であり、R2はHである。
本発明は、減退した記憶力の改善のため化学式(1)で表されるトリテルペン化合物の新しい使用と、化学式(1)で表されるトリテルペン化合物を含む脳機能改善用薬剤組成物に関する。前記化学式(1)のトリテルペン化合物の特定例は、下記化学式(1a)、(1b)及び(1c)でそれぞれ示されるオレアノール酸(oleanolic acid)、ヘデラゲニン(hederagenin)及びウルソール酸(ursolic acid)を含む。
オレアノール酸、ヘデラゲニン及びウルソール酸が、軽度の認知障害及び痴呆に関連する記憶力の減退を生体内で(in vivo)改善するか調べるため、受動的回避実験を行った。
オレアノール酸、ヘデラゲニンとウルソール酸が、ICRマウス(体重:25〜30g、単位投薬当りオス5匹、BGI、Korea)に、各々2.0g/kg、680mg/kg、230mg/kg、75mg/kg単位投薬で、1週間、7回経口投与され、その日に、投薬されたマウスを30分毎に肉眼で観察した。また、投与後2週間、マウスの死亡率、一般状態(general conditions)及び体重を調べ、検死で臓器の異常を観察した。
化学式(1)で表されるトリテルペン化合物10mgをラクトース14.8mg、結晶セルロース3mg、ステアリン酸マグネシウム0.2mgと混合した。混合物を適当な装置を使用してNo.5ゼラチンカプセルに詰めた。

マンニトール ---- 180mg
Na2HPO4・12H2O ---- 26mg
蒸留水 ---- 2974mg
1日の投薬に対して、化学式(1)で表されるトリテルペン化合物0.2g、粉末ビタミンE、乳酸鉄、酸化亜鉛、ニコチンアミド(nicotinic amide)、ビタミンA,B1及びビタミンB2を混合して健康食品を製造した。
有効成分 ---- 300mg
高麗人参抽出物 ---- 100mg
緑茶抽出物 ---- 100mg
ビタミンC ---- 100mg
粉末ビタミンE ---- 120mg
乳酸鉄 ---- 2mg
