Abstract
使用化学式(I)所示化合物作为皮肤增白剂的化妆品组合物和皮肤增白方法,其中:每个X1和/或X2,彼此独立的,各自可以是-H或者是结构式(A)中所示的-COR,-CO2R,-CONHR基团,其中R是C1到C18饱和或者非饱和直链或者支链的烃基,每个R1和/或R2,彼此独立的,各自可以是C1到C18饱和或者非饱和直链或者支链的烃基。
Description
本发明是关于使用雷琐酚衍生化合物的化妆方法和包含了前述化合物,特别是4,6-二取代雷琐酚衍生物作为皮肤增白剂的化妆品组合物。
很多人对于他们的皮肤色素沉着程度很关心。例如,患有老年斑或者雀斑的人可能希望这种色素沉着变得不明显。其他人可能希望减少因太阳曝晒引起的皮肤变黑,或者是淡化他们的自然肤色。为满足此需求,人们作出很多种开发关于降低黑色素细胞中色素生成的产品的努力。但是,迄今确认的物质看起来或者是效果微乎其微或者是出现不希望的副作用,比如,毒性或者皮肤刺激性。所以,对于具有改进的全面效果的新型皮肤增白剂存在着持续的需求。
雷琐酚衍生物具有美容和美发作用。某些雷琐酚衍生物,特别是4-取代雷琐酚衍生物,可用于对皮肤进行增白作用的化妆品组合物中。雷琐酚衍生物在很多出版物中都有描述,包括Hu等人,USP6,132,740;Collington等人,PCT WO 00/56702;Bradley等人,EP 1134 207;Shinomiya等人,USP 5,880,314;LaGrange等人,USP5,468,472;Hiroaki等人,JP11-255638 A2;Torihara等人,USP4,959,393;和日本公开的JP2001-010925和JP2000-327557。
雷琐酚衍生物是已知化合物,可以通过很多种方法容易的获得,包括通过这样一种方法,其中一种饱和的羧酸和雷琐酚在氯化锌的存在下被缩合,所得的缩合物用锌汞齐/盐酸还原(Lille等人,Tr.Nauch-Issled.Inst.Slantsev 1969,No.18:127-134),或者通过这样一种方法,其中雷琐酚和一种相应的烷基醇在氧化铝催化剂的存在下在从200到400℃的高温下反应(英国专利No.1,581,428)。这些化合物有些对皮肤有刺激作用。
申请人现在发现对4,6-二-取代雷琐酚衍生物化合物和包含这些化合物的组合物的使用可以带给皮肤增白作用。这些化合物的通式和结构将在下文中进行深入的讨论。4,6-二-取代雷琐酚衍生物化合物被发现对增白皮肤有效,可以对皮肤刺激更小,但目前尚没有用于增白皮肤。
通式I中化合物,和包含这些化合物的组合物的使用,带给皮肤增白作用,同时还能降低刺激作用。本发明提供和化妆品可接受的赋形剂一起使用的大约0.000001%到大约50%的化学式I所示的化合物的一种化妆品组合物和皮肤增白方法,
其中:
每个X1和/或X2,分别是H或者COR(酰基),CO2R,CONHR基团,后三个基团分别以下面的化学式A来代表:
其中R是C1到C18饱和或者不饱和、直链,支链或者环状的烃基,每个R1和/或R2,分别的可以是C1到C18饱和、或者不饱和,直链,支链或者环状的烃基。
在一种优选的实施方案中,X1和/或X2各个分别或者二者全部代表-H。在一种更加优选的实施方案中,X1和X2全部代表H,这样该化合物就具备如下化学式II,R1和R2基团具有上面化学式I中的定义:
在一种最优选的实施方案中,在上面的化学式II中,R1和R2都代表一个异丙基。
任选地,羟基可以通过本领域已知的方法被进一步取代。例如,其中一个或者全部二个羟基可以用任何一种下面的酸或者酸的组合来酯化:4-羟基-3-甲氧基肉桂酸,4-羟基-3-甲氧基苯甲酸,癸二酸,壬二酸(azaleic acid),苯甲酸,3,4-二羟基肉桂酸,羟苯基丙烯酸,邻羟基苯甲酸,半胱氨酸,胱氨酸,乳酸,和羟基乙酸。
其他的皮肤作用剂可以被加入到对本发明方法所用的组合物中。有机和无机防晒剂也可被加入。
本发明组合物和方法具有有效的皮肤增白特性,可以对皮肤产生较小的刺激,也是经济的。
这里所用的术语”化妆品组合物”是表示局部施用于人体皮肤的组合物。
这里所用的术语”皮肤”包括脸部,颈部,胸部,背部,臂部,腋下,手部,腿部和头皮皮肤。
除了在实施例中所列的,或者被明确的指出的情况之外,其他表示材料数量或者反应条件,材料物理性质和/或用途的数字都应被理解为被”大约”所修饰。所有的数量都是表示基于该组合物的重量,除非另外写明。
请注意,在表示任何浓度范围时,任何特定的较高浓度可以和任何特定的较低浓度相配合。
为避免模糊,单词”包含”表示包含所列物质但不一定表示完全由其构成。换句话说所列的步骤或者选择不一定是穷举的。
皮肤增白衍生物
4,6-二-取代雷琐酚衍生物
本发明是关于作为皮肤增白剂的通式I所示化合物,和包含该化合物的组合物。本发明的组合物和方法的一个特别优势是通式I所示化合物比其他已知皮肤增白化合物对皮肤刺激较小。此外,通式I所示化合物的制备过程也相对简单,更加经济。本发明通过在化妆品可接受的赋形剂中使用大约0.000001%到大约50%的化学式I所示的化合物提供一种化妆品组合物和皮肤增白方法,
其中:
每个X1和/或X2独立的是H或者COR(酰基),CO2R,CONHR基团,后三个基团分别以下面的化学式A来代表:
其中R是C1到C18饱和或者不饱和的直链,支链或者环状的烃基,并且每个R1和/或R2独立的是C1到C18饱和或者不饱和的直链,支链或者环状的烃基。
在一种优选的实施方案中,X1和/或X2各个分别或者二者全部代表H。在一种更加优选的实施方案中,X1和X2全部代表H,这样该化合物就具备如下化学式II(R1和R2基团具有上面化学式I中的定义),
最优选的实施方案化合物可以通过将雷琐酚和异丙醇在酸性催化剂下反应来制备,该酸性催化剂最好是硫酸催化剂(原材料可以从Yick-Vic化工制药(HK)有限公司/香港购买),反应以下面反应式(III)表示:
相似地,若要得到更短或者更长的R1和/或R2基团,应当使用与碳链长度相应的醇。
在化学式II中,可选的,羟基(一个或者全部二个OH基团中的H)可以进一步被通过本领域已知的方法取代,比如雷琐酚和一种酸酐进行的酯化反应。例如,一个或者全部二个羟基可以用下面的任何一种酸(或者相应的酐)或者其组合来酯化:4-羟基-3-甲氧基肉桂酸,4-羟基-3-甲氧基苯甲酸,癸二酸,壬二酸(azaleic acid),苯甲酸,3,4-二羟基肉桂酸,羟苯基丙烯酸,邻羟基苯甲酸,半胱氨酸,胱氨酸,乳酸,和羟基乙酸。
此外,护肤剂可以被加入到对本发明方法所用的组合物中。例如,该组合物可以包含通式I化合物和一种单-取代雷琐酚衍生物的结合,比如4-乙基雷琐酚,4-异丙基雷琐酚,4-丁基雷琐酚,4-己基雷琐酚,和其他在4-位上被取代的雷琐酚衍生物的组合。有机和无机防晒剂,还有香料,也可包括在内。
本发明组合物和方法具有有效的皮肤增白特性,可以比其他皮肤增白剂对皮肤产生较小的刺激,也是容易制造和经济的。
组合物通常包含大约0.000001%到大约50%的化学式I所示的化合物。化学式II所示的化合物是优选的,而R1和R2都表示一个异丙基的化学式II化合物是最优选的。通式I所示化合物的量优选是占化妆品组合物总量的从大约0.00001%到大约10%,更优选是从大约0.001%到大约7%,最优选是从0.01%到大约5%。
优选的化妆品组合物是那些根据本发明的方法适合于应用于人类皮肤的那些,任选的包含一种除了化学式I化合物之外的护肤剂。

实施例1
下面的化合物,通过上面(化学式III)描述的方法制备并用HPLC提纯,在后续的所有实施例中都被使用到:
本发明化合物,其中R1和R2都是异丙基,被称为4,6-二-异丙基雷琐酚。其中R1代表异丙基而R2代表H的化合物被称为4-异丙基雷琐酚。
4-异丙基雷琐酚和4,6-二-异丙基雷琐酚通过下面的HPLC方法被提纯到纯度大于98%(通过气相色谱分析证实):
HPLC系统由下面构成:
Waters 600泵控制器
717+自动取样器
Waters996二极管阵列UV/VIS检测器
Waters馏分收集器
HPLC柱:制造商Phenomenex
250×21.2mm的Sphereclone ODS(2)反相柱,使用5微米粒子填充。
线性梯度洗脱,进行30分钟,70/30水/乙腈变为50/50水/乙腈。
进行分离的流速恒定在10mL/min。
检测器使用波长为280nm。
冲洗时间是:4-异丙基雷琐酚15分钟,4,6-二-异丙基雷琐酚29分钟。
当某种指定的分子被发现洗脱出来,用馏分收集器分导洗脱液到分别的收集烧瓶中,这样每种化合物就可以被独立的保存。
雷琐酚衍生物的纯度用气相色谱分析估算。样本(10mg)用500μl的吡啶和300μl的双(三甲基甲硅烷基)三氟乙酸酰胺(RegisChemical,Morton Grove,Il)在70℃进行衍生反应30分钟。1μl注射进带有HPl交联甲基硅酮柱(25m×0.2mm)的惠普气相色谱柱里。用20分钟通过一个60℃到180℃温度梯度使衍生后的雷琐酚从柱中挥发出来。

实施例12蘑菇酪氨酸酶分析
蘑菇酪氨酸酶的抑制是减少黑色素合成的标志,所以能够给皮肤带来增白效果。本实验显示本发明的雷琐酚衍生物的皮肤增白效果。
在96洞的滴板上每一个洞里,加入150微升磷酸盐缓冲液(100mM,pH7.0),10微升左旋DOPA(左旋-3,4-二羟苯基丙氨酸,10mM),和20微升的皮肤增白剂(溶于乙醇作为控制剂)。在最初的475nm下的背景吸光度的测量之后,加入20微升的蘑菇酪氨酸酶(Sigma T-7755;6050单位/ml)并于室温下培养。
在下述时间点读出在475nm的吸光度:0、2、4和6.5分。将这些数据按照475nm时的吸光度对时间(分)作图,计算线的斜率(ΔAbs475nm/分),数值表示为对于黑色素合成反应的各未处理乙醇对照物的百分数。
下表显示出对于皮肤增白剂化合物4-异丙基雷琐酚类和4,6-二异丙基雷琐酚在浓度范围内的酪氨酸酶试验结果。
IC50值是指皮肤增白剂浓度,该浓度产生相对于对照物的50%的酪氨酸酶抑制作用(目标是在最小浓度时得到最大活性)。
