- the production method according to [7] including a step of using a homogenizer.
- Liposome particle size measurement SEISHIN LMS-350 (manufactured by Seishin Enterprise Co., Ltd.) was used to determine the particle size distribution by dispersing in water. In this apparatus, 0.1 ⁇ m is the lower limit of detection.
- Comparative Example 1 Preparation of Liposome Composition Using 0.3 g of PQQ disodium and 3.0 g of COATSOME NC-21 (hydrogenated soybean phospholipid), water was mixed so that the whole became 100 g. The pH at this time was 3.5. While heating the obtained solution to 60 ° C. or higher, it was treated with NISSEI AM-3 homogenizer (manufactured by Nippon Seiki Seisakusho Co., Ltd.) for 30 minutes and 7000 rpm, then lowered to room temperature and treated for 10 minutes and 7000 rpm. After the treatment, water with reduced evaporation was added. This was used as the liposome composition of Comparative Example 1.
- NISSEI AM-3 homogenizer manufactured by Nippon Seiki Seisakusho Co., Ltd.
- Example 1-4 Using 0.3 g of PQQ disodium and 3.0 g of COATSOME NC-21 (hydrogenated soybean phospholipid), sorbitol was added at 2, 10, 20, and 40 g, and water was mixed so that the whole became 100 g. The pH at this time was 3.5. The temperature was 60 ° C. The obtained solution was treated in the same manner as in Comparative Example 1 to prepare the liposome composition of Example 1-4.
- Comparative Example 2 Preparation of Liposome Composition Containing Sugar Without PQQ Using COATSOME NC-21 (hydrogenated soybean phospholipid) 3.0 g and sorbitol 10 g, water was mixed so that the whole would be 100 g. A liposome composition was prepared by treating in the same manner as in Comparative Example 1.
- Comparative Example 3 Production of Liposome Composition Containing Small Size Soy lecithin 0.3 g, PQQ disodium 0.3 g, and sorbitol 10 g were mixed with water so that the whole would be 100 g. The same operation as in Comparative Example 1 was performed to prepare a liposome composition.
- the liposome compositions prepared in Examples 1 to 4 and Comparative Examples 1 to 3 and PQQ disodium were used, and these samples were diluted with a medium and tested. Test concentrations were 500, 250, 125, 62, 31, 16, 8, 4, 2, 1, 0.5, 0 ⁇ M. In Comparative Example 2, the concentration of the liposome composition was used. Each test was run twice and averaged. The results are shown in FIG. The vertical axis is a value where the cell concentration without addition was taken as 100.
- the added amount at which the total number of cells is reduced by about 10% compared with no addition is defined as the growth arresting concentration (absorption is improved when this concentration is lowered), and the cell concentration is about 5% compared with no addition.
- the higher concentration was defined as the growth promoting concentration, and the test results of each sample are shown in Table 2.
- the addition amount at which the total cell number was reduced by 10% compared with the medium alone was 500 ⁇ M PQQ disodium in Comparative Example 4 and 62 ⁇ M in the liposome composition without Comparative Example 1 with sorbitol added. On the other hand, it was 31 micromol in the comparative example 3 containing a small liposome composition. The growth-stopping concentration became more absorbable due to liposome formation, and the effect appeared at a low concentration. As for the growth promoting concentration, Example 1-4 was more effective than Comparative Example 1 over a wide concentration range. When PQQ and sugar were added to the liposome, the growth arresting concentration was increased, and the growth inhibitory effect was reduced by the addition of sugar.
- the sugar-added liposome composition of Comparative Example 2 to which PQQ was not added had an effect on cell growth at an equivalent of 500 ⁇ M, but no other effects. Further, in the small liposome composition of Comparative Example 3, growth inhibition appears at a low concentration, and no growth promoting effect is observed (it is expected that the concentration is lower than the test range).
- the concentration at which about 5% growth promotion by PQQ was unexpectedly observed was in a wide concentration range as the addition of sugar increased. It was effective from a low concentration to a high range. It is thought that the composition selection at the time of adding to a culture medium becomes easy because the density
- Example 5 PQQ disodium 0.3 g, sorbitol 10 g, and COATSOME NC-21 (hydrogenated soybean phospholipid) 3.0 g were mixed with water so that the total amount was 100 g.
- the pH at this time was 3.5.
- the temperature was 40 ° C. While increasing the temperature of the obtained solution and finally heating to 60 ° C. or higher, treatment with NISSEI AM-3 homogenizer for 30 minutes and 7000 rpm, then lowering to room temperature and treating for 30 minutes and 7000 rpm did. After the treatment, water whose evaporation decreased to a total weight of 100 g was added.
- the particle size measurement result of the liposome produced in Example 5 is shown in Table 3 below, and the particle size distribution result is shown in FIG.
- Examples 6 and 7 PQQ disodium 0.3 g, sorbitol 50 or 0.5 g, and COATSOME NC-21 (hydrogenated soybean phospholipid) 3.0 g were mixed with water to a total of 100 g. The pH at this time was 3.5. The temperature was 60 ° C. Liposome compositions were prepared in the same manner as in Examples 1 to 4.
- Examples 8-12 PQQ disodium 0.3 g, COATSOME NC-21 (hydrogenated soybean phospholipid) 3.0 g, and the weight of sugar shown in Table 6 were used, and water was mixed so that the whole would be 100 g. The pH at this time was 3.5. The temperature was 60 ° C. The obtained solution was treated with NISSEI AM-3 homogenizer as follows to prepare the liposome composition of Examples 8-12.

ピロロキノリンキノンジナトリウムは三菱ガス化学、COATSOME NC-21(水素添加大豆リン脂質)は日本油脂、その他はWAKOの試薬を使用した。
SEISHIN LMS-350(セイシン企業社製)を使用して、水に分散して粒度分布を求めた。この装置では0.1μmが検出下限である。
PQQジナトリウム0.3g、COATSOME NCー21(水素添加大豆リン脂質)3.0gを用い、水を全体が100gになるように混合した。この時のpHは3.5であった。得られた溶液を60℃以上に加温しながら、NISSEI AMー3ホモジナイザー(株式会社日本精機製作所社製)で30分、7000回転、その後、室温に下げ、10分、7000回転で処理した。処理後、蒸発減少した水分を追加した。これを比較例1のリポソーム組成物とした。
PQQジナトリウム0.3g、COATSOME NCー21(水素添加大豆リン脂質)3.0gを用い、ソルビトールの添加を2,10,20,40gで行い、水は全体が100gになるように混合した。この時のpHは3.5であった。また、温度は60℃であった。得られた溶液を比較例1と同様に処理して、実施例1-4のリポソーム組成物を作製した。
COATSOME NCー21(水素添加大豆リン脂質)3.0g、ソルビトール10gを用い、全体が100gとなる様に水を混合した。比較例1と同様に処理してリポソーム組成物を作製した。
大豆レシチン0.3g、PQQジナトリウム0.3g、ソルビトール10gを用い、全体が100gとなる様に水を混合した。比較例1と同様の操作を行いリポソーム組成物を作製した。
ソルビトールの添加による粒子径の変化は小さく、糖添加によるリポソームの粒子径への影響はないことが分かった。PQQ添加の有無も粒子径への影響はないことが分かった。
比較例3は一般的な大豆レシチンにすることで小さな粒子を含むリポソームを作ることができ、小さな粒子の影響を見ることができる。
チャイニーズハムスター卵巣細胞(CHO-DHFR;大日本住友製薬より入手)をα-MEM+10%牛胎児血清の培地で5%CO2, 37℃で培養した。イワキ製96穴プレートを使用し、1個の穴に5000個の細胞になるように100μlの培地とともに加え、一晩培養した。培養液を抜き、所定の試験濃度の実施例1ー4、比較例1ー3で調製したリポソーム組成物を含む培地を加えた。1日培養後、培地を入れ替え同仁化学 WSTアッセイキットを使用して1時間反応させ、450nmの吸光度を測定した。この時の吸光度は細胞数に比例する。
増殖促進濃度は、比較例1より実施例1-4の方が広い濃度範囲で有効であった。
リポソームにPQQと糖を添加すると増殖停止濃度は上がり、増殖抑制効果は糖の添加により、小さくなった。
比較例2のPQQを添加しない糖添加のリポソーム組成物では500μM相当では細胞増殖に影響がみられたが、その他では影響がない。また、比較例3の小さなリポソーム組成物では低い濃度で増殖阻害が現れ、増殖促進効果は見られない(試験範囲よりも低い濃度になっていると予想される)。
細胞の増殖を促進する濃度が広くなることで培地に添加する際の組成選択が容易になると考えられる。
PQQジナトリウム0.3g、ソルビトール10g、COATSOME NCー21(水素添加大豆リン脂質)3.0gに、水を全体が100gになるように混合した。この時のpHは3.5であった。また、温度は40℃であった。得られた溶液の温度を上げながら、最終的に60℃以上になるように加温しながら、NISSEI AM-3ホモジナイザーで30分、7000回転、その後、室温に下げ、30分、7000回転で処理した。処理後、合計重量100gになるように蒸発減少した水分を追加した。
PQQジナトリウム0.3g、ソルビトール50または0.5g、COATSOME NCー21(水素添加大豆リン脂質)3.0gに、水を全体が100gになるように混合した。この時のpHは3.5であった。また、温度は60℃であった。実施例1~4と同様に処理してリポソーム組成物を作製した。
また、糖の濃度が0.5重量%、50重量%でも広い濃度範囲で増殖促進できることが確認された(実施例6および7)。
PQQジナトリウム0.3g、COATSOME NCー21(水素添加大豆リン脂質)3.0g、糖を表6に示す重量を用い、全体が100gとなるように水を混合した。この時のpHは3.5であった。また、温度は60℃であった。得られた溶液のNISSEI AMー3ホモジナイザーによる処理は以下のように行い、実施例8-12のリポソーム組成物を作製した。
実施例8:80℃以上に加温しながら1時間、7000回転
実施例9:40℃以上に加温しながら30分、7000回転
実施例10:60℃以上加温しながら30分、7000回転、その後、室温に下げ、1時間、7000回転
実施例11および12:60℃以上加温しながら30分、7000回転
また、糖については、糖アルコールのみならず単糖、二糖でも広い濃度範囲で増殖促進できることが確認された(実施例11および12)。
