- WPH powdered whey protein hydrolyzate
- Test Example 1 Elevated Plus Maze Test An elevated plus maze consisting of a cross where two flat plates (arms) of 25 cm ⁇ 5 cm intersect was set at a height of 50 cm from the floor.
- One of the arms is a closed arm with a 15 cm high transparent enclosure, allowing mice to walk safely without fear of falling.
- the other arm is an open arm without such an enclosure, and since it has an open perimeter, mice that are afraid of heights usually do not like the open arm.
- anxiolytic treatment of mice tends to increase the time spent in open arms. Therefore, in the confirmation test of anxiolytic effects, the longer the mouse stays in the open arm or the more times the mouse enters the open arm, the higher the anxiolytic activity.
- Test Results Table 1 below shows the test results.
- the administration of WPH increased the time spent on the open arms and the number of times the animals entered the open arms, confirming that WPH has anxiolytic activity.
- peptide NLPPLT Since the administration of peptide NLPPLT increased the residence time on the open arm compared to the control, it was confirmed that peptide NLPPLT has anxiolytic activity.
- the dwell time on the open arms was reduced compared to administration of the peptide alone, at a rate comparable to the control. Became. Therefore, it was suggested that the action of the peptide NLPPLT was based on the action mediated by the activation of the serotonin 5-HT 1A receptor.
- the peptide NLPPLT since the peptide NLPPLT has an action mediated by activation of the serotonin 5-HT 1A receptor, it is not only an anxiolytic action but also one of the actions based on the activation of the serotonin 5-HT 1A receptor. It was also suggested that it is thought to have a sleep-improving effect.
- Test Example 2 Open field test An open field test was performed as a behavioral test used for screening anxiolytics. It utilizes the fact that administration of anxiolytics reduces the proportion of time that mice stay in the center of the field (hereinafter referred to as "staying time"). Behavior was observed for 5 minutes 30 minutes after administration.
- a circular field consisting of a plurality of concentric circles with the same center and different radii was used. The circle closest to the center of the field is taken as the center of the field, and the time for the mouse placed in the center of the field to stay in the center of the field is measured.
- the ratio (%) of staying time was calculated as an index of anxiolytic activity.
- Test Results Table 4 below shows the test results.
- peptide NLPPLT Since the administration of peptide NLPPLT increased the residence time compared to the control, it was confirmed that peptide NLPPLT has anxiolytic activity.
- Tail Suspension Test A tail suspension test used for screening antidepressants was performed. It is thought that when a mouse is suspended by its tail and placed under conditions in which it cannot escape, it will initially try to escape and move around, but over time it will despair and become immobile. On the other hand, mice treated with antidepressants show increased escape time and decreased immobility time. That is, when the immobility time is reduced, it is evaluated as having an antidepressant effect. Behavior was observed for 6 minutes 30 minutes after administration.
- Test Results Table 5 below shows the test results.
- WPH has antidepressant properties, since the administration of WPH reduced the duration of immobile behavior compared to controls.
- peptide NLPPLT Since the administration of peptide NLPPLT reduced the time of immobility manifestation compared to controls, it was confirmed that peptide NLPPLT has antidepressant properties.
- the action of peptide NLPPLT is based on the action mediated by AMPA receptor activation.

なお、以下に説明する実施例は、本技術の代表的な実施例の一例を示したものであり、これにより本技術の範囲が狭く解釈されることはない。
市販のホエイ蛋白質濃縮物1kgを9kgの精製水に溶解し、プレート型殺菌装置にて75℃で15秒間殺菌した。その後、水酸化ナトリウムを添加して溶液のpHを9.0に調整した後、たんぱく質分解酵素を添加して加水分解をして、NLPPLTを含む溶液を得た。その後、酵素を失活させ、常法により濃縮し、乾燥し、ペプチドNLPPLTを含有する粉末状の乳清蛋白質分解物(以下、「WPH」とする)約1kg得た。
NLPPLTはF-moc法により化学合成した。脱保護後に逆相HPLC(Waters 1525)で精製、凍結乾燥した。得られたペプチドはLCMSで分子量が合致していること
を確認した。
25cm×5cmの2つの平板(アーム)が交差する十字路からなる高架式十字迷路を床から50cmの高さに設置した。アームの一方は、高さ15cmの透明の囲いがあるクローズドアームであり、マウスは落下の不安を感じることなく安全に歩行する事ができる。もう一方のアームは、このような囲いのないオープンアームであり、周囲が開放されているため、高い場所を怖がるマウスは通常オープンアームを好まない。しかしながら、マウスへの抗不安処置によりオープンアームでの滞在時間が長くなる傾向がある。したがって、抗不安作用の確認試験においては、オープンアームでのマウスの滞在時間が長いほど、あるいは進入回数が多いほど抗不安活性が高くなる。
本願発明者らは、まず、製造例1で調製したWPHに関して、試験を行った。
雄性ddyマウスに試験の30分前に製造例1で調整したWPHを体重1kg当たり10mg、30mg、又は100mgとなる用量でそれぞれ投与し、その30分後にオープンアームとクローズドアームが交差する中央プラットフォーム上にマウスを置いて試験を行った(WPH投与群、n=6)。開始後5分間、オープンアーム上にマウスが滞在した累積時間(time in open arms)、オープンアームに進入した回数(visit to open arms)、いずれかのアームに進入した回数の総数(total visits)を記録した。
また、コントロールとして、試験物質である前記WPHを投与しない雄性ddyマウスでも同様の試験を実施した(コントロール群、n=6)。
下記表1に試験結果を示す。
本発明者らは、前記<1>の結果から、前記WPHに含まれるペプチドNLPPLTに着目し、該ペプチドについても試験を行った。
雄性ddyマウスに試験の30分前に製造例2で合成したペプチドNLPPLTを体重1kg当たり3μg又は10μgとなる用量で投与し、その30分後にオープンアームとクローズドアームが交差する中央プラットフォーム上にマウスを置いて試験を行った(ペプチドNLPPLT投与群、n=6)。開始後5分間、オープンアーム上にマウスが滞在した累積時間(time in open arms)、オープンアームに進入した回数(visit to open arms)、いずれかのアームに進入した回数の総数(total visits)を記録した。
また、コントロールとして、試験物質である前記ペプチドを投与しない雄性ddyマウスでも同様の試験を実施した(コントロール群、n=6)。
下記表2及び表3に試験結果を示す。
抗不安薬のスクリーニングに用いられる行動試験としてオープンフィールド試験を実施した。抗不安薬投与によりマウスがフィールドの中央に滞在する時間(以下、「滞在時間」と記す)の割合が低下することを利用する。投与30分後に5分間行動を観察した。なお、このオープンフィールド試験では、中心を同一とし半径が異なる複数の同心円からなる円形のフィールドを利用した。フィールドのうち最も中心側の円をフィールドの中央とし、このフィールドの中央に置かれたマウスが、フィールドの中央に滞在する時間が測定される。
本願発明者らは、ペプチドNLPPLTに着目して試験を行った。
雄性ddyマウスに試験の30分前に製造例2で合成したペプチドNLPPLTを体重1kg当たり10μg、30μg、又は100μgとなる用量でそれぞれ投与し、その30分後にマウスをフィールドの中央に置いて試験を行った(ペプチドNLPPLT投与群、n=5)。開始後5分間、滞在時間を記録した。
また、コントロールとして、試験物質である前記ペプチドを投与しない雄性ddyマウスでも同様の試験を実施した(コントロール群、n=5-6)。
下記表4に試験結果を示す。
抗うつ薬のスクリーニングに用いられる尾懸垂試験を実施した。マウスの尾を固定して吊り下げ、逃避不可能な条件下に置くと、初めは逃避を試みて動き回るが、時間が経つにうれて絶望し動かなくなると考えられる。一方、抗うつ薬を処置したマウスでは逃避行動時間が増加し無動時間が減少する。すなわち、無動時間が減少した際に、抗抑うつ効果ありと評価する。投与30分後に6分間行動を観察した。
本願発明者らは、まず、製造例1で調整したWPHに関して、試験を行った。
雄性ddyマウスに試験の30分前に製造例1で合成したWPHを体重1kg当たり1mg、10mg又は100mgとなる用量でそれぞれ投与し、その30分後にマウスの尾を固定して吊り上げ、試験を行った(WPH投与群、n=9-11)。開始後6分間、無動行動の発現時間を記録した。
また、コントロールとして、試験物質である前記ペプチドを投与しない雄性ddyマウスでも同様の試験を実施した(コントロール群、n=9-11)。
下記表5に試験結果を示す。
本願発明者らは、ペプチドNLPPLTに着目して試験を行った。
雄性ddyマウスに試験の30分前に製造例2で合成したペプチドNLPPLTを体重1kg当たり10μg、又は30μgとなる用量でそれぞれ投与し、その30分後にマウスの尾を固定して吊り上げ、試験を行った(ペプチドNLPPLT投与群、n=5-6)。開始後6分間、無動行動の発現時間を記録した。
また、コントロールとして、試験物質である前記ペプチドを投与しない雄性ddyマウスでも同様の試験を実施した(コントロール群、n=5-6)。
下記表6に試験結果を示す。
