Description

神经酰胺和 /或葡萄糖神经酰胺产生促进剂的制造方法 技术领域
'本发明涉及能够促进皮肤产生神经酰胺和 /或葡萄糖神经酰胺的神 经酰胺产生促进剂和 /或葡萄糖神经酰胺产生促进剂的制造方法。 本发 明特别涉及利用特定微生物, 以食品加工业等的副产物豆渣作为培养 基的主原料, 制造能够促进皮肤产生神经酰胺和 /或葡萄糖神经酰胺的 神经酰胺和 /或葡萄糖神经酰胺产生促进剂的方法。 背景技术
皮肤具有产生神经酰胺 (ceramide ) 和葡萄糖神经酰胺 ( glucosylceramide ) 的能力。 在皮肤中、 特别是表皮角质层中聚集着 由表皮细胞合成分泌得到的神经酰胺, 它是细胞间脂质的主要成分。 神经鞘脂类之一的神经酰胺存在于皮肤角质层中, 占角质层中细胞间 脂质的 50 %左右。 神经鞘脂类 (Sphingolipid) 是具有鞘氨醇骨架的复 合脂质的总称。 葡萄糖神经酰胺是在神经酰胺上结合了葡萄糖而成的 一种神经鞘脂类。 而由表皮细胞合成得到的神经酰胺暂时以葡萄糖神 经酰胺或者神经鞘磷脂 (sphingomyelin ) 的形式被储存起来; 之后被 排出至细胞外, 在葡糖脑苷酯酶 (glucocerebrosidase ) 和神经磷脂酶 ( sphingomyelinase ) 的作用下, 再次形成神经酰胺, 从而发挥作为细 胞间脂质的功能。 皮肤中的神经酰胺和葡萄糖神经酰胺具有提高皮肤 的保湿功能和皮肤的屏障功能等的生理作用。
一直以来, 已知神经酰胺、 葡萄糖神经酰胺、 半乳糖神经酰胺等 神经鞘脂类具有促进角质层的保持水分能力、改善皮肤粗糙等效果(专 利文献 1〜2)。 虽然皮肤具有产生神经酰胺和葡萄糖神经酰胺的能力, 但是, 近来由于环境、 气候等的影响, 皮肤容易变得干燥, 因此由皮 肤自身产生神经酰胺等来改善皮肤的保湿功能就显得不足够。
因而人们尝试了从外部向皮肤补充神经酰胺的方法。 例如, 在专 利文献 3中记载了培养假丝酵母(0« ¾¾)属的热带假丝酵母(Owifefe tropicalis ) JPCCY0004株 (NITE P-570 ) 来制造葡萄糖神经酰胺的方 法, 通过将该葡萄糖神经酰胺涂布在人体的干燥性库肤上能够改善皮 肤的保湿功能。 但是, 该方法并不是关于神经酰胺和 /或葡萄糖神经酰 胺产生促进剂的方法, 而只不过是直接从培养后的菌体中获取大量存 在的葡萄糖神经酰胺, 因此所合成的葡萄糖神经酰胺的神经酰胺骨架 与人体中存在的神经酰胺类的神经酰胺骨架不同, 其在两处具有碳碳 双键且具有支链。 因此, 将这种从微生物中直接提取得到的葡萄糖神 经酰胺涂布在人体皮肤上的话, 有可能不能与人体皮肤相适应而产生 使用安全性方面的问题。
另外, 从外部向皮肤补充神经酰胺的方法与以往使用的保湿剂等 同样有保湿效果的持续性不够的问题, 而且有些状态的皮肤对从外界 补给的神经酰胺等的吸收不充分, 从而导致不能充分发挥保湿效果。
而另一方面, 如果能够增强或促进皮肤本身的神经酰胺或葡萄糖 神经酰胺的产生能力, 则无需从外部补充神经酰胺或葡萄糖神经酰胺, 而能够通过促进皮肤自身产生神经酰胺和 /或葡萄糖神经酰胺来提高皮 肤的屏障功能和保湿功能。 这样, 由于是由皮肤自身产生神经酰胺或 葡萄糖神经酰胺, 所合成的是皮肤所具有的常规结构的神经酰胺等, 因而其不存在与皮肤的适应性不好等的安全性问题。
因此最近关于在皮肤角质层中产生促进表皮神经酰胺等的生成的 物质的研究相当热门。 其中, 作为能够促进神经酰胺生成的物质, 已 报道的有以灵芝、蜂花粉(Bee Pollen )、川芎等的提取物为有效成分的 神经酰胺产生促进剂(专利文献 4〜6)。然而, 由于这些神经酰胺产生 促进剂全都是从植物原料提取轉到, 其提取操作耗费时间长, 且在天 然资源的可利用性方面有限制, 因而其制造成本高。
另外, 在专利文献 7 中, 公开了一种能够活化皮肤表层内部的表 皮细胞自身的神经酰胺合成的神经酰胺合成促进剂, 其以含有烟酸和 / 或烟酰胺的菌培养物为有效成分, 该菌培养物可以是乳酸菌培养物、 双歧杆菌培养物、 香菇菌体培养物或者酵母菌培养物。 然而, 从专利 文献 7的实施例可以看出, 不含有烟酸和 /或烟酰胺的乳酸菌培养物或 者酵母菌培养物 (比较例 〜 4) 的神经酰胺产生量较之对照组并无明 显变化, 因而该神经酰胺合成促进剂实质上含有烟酸和 /或烟酰胺作为 有效成分, 其神经酰胺合成促进效果还不够充分, 尚有改善的余地。 而且, 由于该促进剂的制备过程中使用的培养基实质上以烟酸和 /或烟 酰胺作为有效成分, 因此这种神经酰胺合成促进剂的制备成本较高。
另外, 酵母菌是一些单细胞真菌, 在自然界分布广泛, 主要生长 在偏酸性的潮湿的含糖环境中。 可在缺氧环境中生存。 可用于酿造生 产。 目前已知有 1000 多种酵母, 可以列举出裂殖酵母属 iSchizosaccharomyces) 酵母、 毕赤 Pichia 属酵母、 假丝酵母属 Candida) 酵母、 德巴利酵母属 iDebaryomyces 酵母、 隐球酵母属 iCryptococcus)酵母、 汉逊酵母属 (Hamenu )酵母、 布勒掷抱酵母 属 BuUera 酵母、 红酵母属 ί Rhodotoruki 酵母、 掷孢酵母属 (Sporobolomyces 酵母、 酒香酵母属 <iBrettanomyces> 酵母、 亚罗酵 母属 ( mwa) 酵母等。
裂殖酵母属 Schi麵 ccharomyces 酵母一直以来被用于食品加工 中, 其发酵产生乙醇, 并且也被用作生物学的研究材料。
另外, 毕赤 Pichia 属酵母具有如下性质和用途等。
毕赤酵母属菌种细胞呈球形、 椭圆形、 拉长形, 偶尔呈锥形, 但 不形成尖顶。 无性繁殖方式为多边芽殖, 有些种类可形成节孢子。 每 个子囊通常包含 1〜4个子囊孢子, 偶尔多于 4个。 孢子呈帽状、 半球 形或球形有棱。 子囊成熟后一般裂幵, 少数不裂开, 接合或不接合形 成子囊, 接合在母细胞和芽体或两个独立细胞之间发生。 菌丝和假菌 丝都可作为子囊, 但形态不会变大或变成纺锤形, 同宗或异宗配合; 可同化硝酸盐, DBB反应阴性。
毕赤 Pichia 属酵母的分类地位为: 子囊菌门 ( o? >^to)、 半 子囊菌纲 {Hemiascomycetes)、 酵母目 Saccharomycetales)、 酵母菌禾斗 {Saccharomycetaceae)、 毕赤酵母属 (尸czz'o)。
毕赤 iPichia 属酵母的用途有, 例如, 利用甲醇产生一些有用物 质, 如抗生素, 生物蛋白等; 或者也可以作为基因工程菌运用。 巴斯 德毕赤酵母用于生产还原型谷胱甘肽, 还有别的一些毕赤酵母用于生 产一些蛋白质 /酶类。
另外, 己知假丝酵母属 (Ccmdick 的微生物通常具有以下用途: 例如, 粗状假丝酵母 (Candida valida 用于生产脂肪酶, 热带假丝酵 母 Candidametapsilosis 、产阮假丝酵母 ( cmdida utilis 等用于生产 酿酒、 甘油、 食用酵母、 有机酸以及酶制剂等, 也可用于词料工业; 并且, 假丝酵母属 Ccmdida 的微生物还可用于处理工业和农副产品 加工业的废弃物、 生产可食用的蛋白质。
另外, 已知德巴利酵母属 (Debaryomyces 的微生物一般具有以 下工业用途, 例如, 发酵葡萄糖生产 D-阿拉伯糖醇、 或者将木糖转化 成木糖醇。
另夕卜,人们对隐球酵母属 Cryptococcus 的微生物已有一些研究。 例如, 有文献报道称乳酒隐球酵母变种产生 β-半乳糖苷酶。 另外, 人 们也发现罗伦隐球酵母 Cryptococc laurentii) 菌株具有对贮藏柑橘 酸腐细菌 (Geotrichum citri-aurantii ) 的抑制作用。
另外, 已知汉逊酵母属 ficm歸 la 的微生物大多能产生乙酸乙 酯, 从而增加产品香味, 因此通常用于酿酒和食品工业。
另外, 已知布勒掷孢酵母属 Bi le 的微生物一般用于食品发 酵, 如香肠发酵。
另外, 人们对红酵母属 Rhodotorula 的微生物己有一些研究。 例如, 红酵母属的某些种对烃类有弱氧化作用, 并能合成 β-胡萝卜素。 如粘红酵母粘红变种能氧化垸烃生产脂肪,含量可达干生物量的 50~60 %。 在一定条件下还能产生 a-丙氨酸和谷氨酸, 产蛋氨酸的能力也很 强, 可达干生物量的 1 %。
另外, 已知掷孢酵母属 Sporobolomyces 的微生物在菌体内蓄积 辅酶 Q10等产业上有用。 另夕卜, 掷孢酵母属 Sporobo myces 的微生 物还作为类胡萝卜素类、 L-肉碱等有用物质的生产菌备受关注。
另外, 已知酒香酵母属 Brettanomyces 的微生物属于酵母的一 种, 在自然界中广泛存在, 通常在木桶储藏中繁殖并产生乙基苯酚。 因而, 在酿酒工业上, 其作为破坏啤酒、 葡萄酒等香气的污染菌, 通 常不受欢迎。
另外, 已知解脂亚罗酵母 ( rra 'a lipolytica ) 等亚罗酵母属 ( Yarrowia 的微生物, 对于多不饱和脂肪酸 (PUFA ) 的生成尤为有 用。
但是, 目前还没有利用酵母菌 (特别是上述各属的酵母) 来制备 神经酰胺产生促进剂或葡萄糖神经酰胺产生促进剂的报道。 专利文献 1 日本特开昭 61 -260008号公报

然后, 在上述 12 孔板中更换不含有生长因子的培养基, 将样品 1 -A、 1 -B和对照品 (浓度为 5(^ %的乙醇水溶液) 分别加入上述 12 孔板中 (n=2), 相同培养条件下培养 3天。
3天培养后, 弃去上清培养液, 以 2ml PBS (磷酸盐缓冲液)对细 胞进行 2次清洗, 再加入 lml的 PBS至板孔中, 以细胞收集器 (细胞 铲) 收集细胞至试管中, 以备后续神经酰胺 /葡萄糖神经酰胺和蛋白质 分析。

( 1 ) 神经酰胺 /葡萄糖神经酰胺量的分析
在由此得到的上清液 a中加入 PBS:氯仿 =1.25ml: 1.25ml的溶剂, 进行振动 20分钟,进行离心(3000rpm, 5分钟)分离,得到上下两相。 回收下相, 并在 30Ό、氮气保护下进行干燥 40分钟。在得到的干燥品 中加入 100 / l的氯仿: 甲醇 =2ml: 1ml的溶剂进行溶解, 并用下述薄 板层析 (TLC) 法对其进行神经酰胺和葡萄糖神经酰胺的量 (分别记 为 Cer和 GlyCer, 单位为 ut g/ml) 的解析。
将神经酰胺(或葡萄糖神经酰胺)标准品与样品溶液点至干燥 TLC 板上, 以 CHCB: CH30H: CH3COOH ( 190: 9: 1 v/v/v) 为展层剂 进行薄板层析, 待展层剂行至薄板顶端, 以吹风机吹干展层剂; 重复 以上步骤一次。 然后以 CHCB : CH30H: C3H60 (76: 20: 4 v/v/v) 为展层剂进行薄板层析, 待展层剂行至距薄板底端 2.5cm处, 停止展 层, 以吹风机吹千。 喷以硫酸铜磷酸溶液, 吹干, 将层析板放置于 180 °C烘烤板上烘烤 7分钟显色。 扫描显色 TLC板并进行神经酰胺 (或葡 萄糖神经酰胺) 分析。
