Description

一种5-甲基色酮及其制备方法和应用
技术领域
本发明涉及美白护肤品技术领域,特别涉及一种5-甲基色酮及其制备方法和应用。
背景技术
美白护肤品的使用具有非常悠久的历史,并伴随着人类自身的存在和发展而流传至今。皮肤白皙与润泽是东方女性的追求,因此美白护肤品颇受爱美人士青睐。最早人们借助物理性的遮盖进行美白(如粉饼、粉底和增白粉蜜等),上世纪50年代开始转变为外用汞制剂还原黑色素的生理性美白,由于汞制剂会对皮肤造成刺激,对中枢神经系统的影响很大,使人出现记忆力衰退、失眠等症状,因而汞制剂在70年代被禁用。氢醌于60年代在国内外开始将其用于化妆品的增白剂以及皮肤科治疗色素沉着症的外用制剂,随后发现氢醌在淡化肤色的同时也产生了许多副作用,长期使用氢醌还会引发外源性白斑病和褐黄病。欧盟(EU)于2002年1月2日起禁止在化妆品中添加氢醌。近年来随着人们对黑色素生成生物学机制的不断认识,加之化学美白剂存在的安全性问题,从天然产物中寻找安全高效的美白活性物质具有很好的发展前景,已成为化妆品研究的热点。
酪氨酸酶(单酚或二酚,氧化还原酶,EC1.14.18.1)是一种位于黑素体的膜内,结合的3型多功能含铜糖蛋白。酪氨酸酶仅由黑素细胞产生,它在内质网和高尔基体内产生并加工后,转运到黑素小体,在黑小素体中催化合成黑色素。因此,通过抑制酪氨酸酶来调节黑色素合成是防止色素沉着的主要方式。因为酪氨酸酶是通过黑素细胞生成黑色素的关键酶,因此直接抑制酪氨酸酶催化活性是抑制黑色素生成最突出、最有效的靶点,市面上大多数化妆品的美白剂多是酪氨酸酶抑制剂。
芦荟含有一种重要的色酮——芦荟苦素,芦荟苦素通过在非细胞毒性浓度下竞争性抑制酪氨酸酶来减少黑色素的形成,从而使皮肤美白;临床上也验证了芦荟苦素的美白和对UV-B的防护作用,因而芦荟苦素在化妆品工业中用作美白剂。然而,芦荟苦素在芦荟中的含量极低,含量高的库拉索芦荟中芦荟苦素含量也仅为0.32‰,分离纯化成本过高,另一方面由于分子中的C-糖基部分而难以合成,工业化不易,限制了芦荟苦素的广泛应用。
