Abstract
本发明涉及雷琐酚衍生物作为皮肤增亮剂的应用。
Description
本发明涉及雷琐酚衍生物(即4-(2,4-二羟基苯基)环己醇)作为皮肤增亮剂的应用。
术语“增亮剂”和“脱色素剂”在本文中可互换应用。
人类皮肤的颜色是由一类独特的细胞(称为黑素细胞)内进行的一系列复杂的细胞过程引起的。黑素细胞位于表皮更深处,它们的作用是合成一种色素(黑素),黑素保护身体以防紫外线辐射的伤害作用。
当皮肤暴露于紫外线辐射中(例如在阳光下)时,黑素细胞增大它们的黑色合成。黑素沉积于黑素体(它是见于细胞中的小泡)中。黑素体被角质形成细胞(它使含黑素的黑素体内在化)挤出细胞并带到皮肤表面。最后的结果是,皮肤的可见层表现为棕色(一般被称为“晒黑的皮肤”)。皮肤中见到的颜色深度与黑素细胞合成、并被转移到角质形成细胞的黑素的量成正比。
形成皮肤色素沉着(即黑素原生成)的机制特别复杂,大致包括如下主要步骤:酪氨酸→L-多巴→多巴醌→多巴色素→黑素。该系列中的前两步反应是通过酶(酪氨酸酶)催化的。酪氨酸酶的活性通过α-黑素细胞刺激激素的作用或UV射线的作用而促进,使黑素作为异常着色而最终形成于皮肤内。已充分证实,如果某物质直接作用于正常发生黑素原生成的表皮黑素细胞的活力和/或如果它干扰黑素生物合成的步骤之一,这种物质就具有脱色素效果。应用于本发明的各种方法和组合物中的活性化合物抑制酪氨酸酶,所以抑制或减少黑素生物合成。
强烈需要能使既有的沉着部位(例如斑点或雀斑)恢复到正常皮肤色的作用剂。为此,开发了各种作用剂和方法并投放到市场。这样的方法实例有:(a)一种方法,其中,大量口服具有良好减轻能力的维生素C(L-抗坏血酸);(b)一种方法,其中,肠胃外施用谷胱甘肽;(c)一种方法,其中,施用一种被认为对蜜胺具有漂白作用的过氧化物,例如过氧化氢、过氧化锌、过氧化钠等;以及(d)一种方法,其中,以软膏、乳膏、洗剂等的形式局部施用维生素C或半胱氨酸。维生素C具有稳定性问题,它在含水体系中变得如此不稳定,以致体系中将引起气味和颜色的变化。硫醇化合物(例如谷胱甘肽和半胱氨酸)不表现令人满意的脱色素效果,因为这种效果的形成很慢。
目前作为脱色素剂应用最广的物质尤其是氢醌及其衍生物,特别是它的醚(例如氢醌一甲基醚)。这些化合物虽然有效,但已知它们产生可能危险的副作用。氢醌(它的应用限于2%的浓度)既是刺激性的,又对黑素细胞存在细胞毒性。
美国专利4,526,179涉及一些氢醌脂肪酯,它们具有良好的活性,并且比氢醌刺激性更小和更稳定。
日本专利申请No.27909/86涉及其它的氢醌衍生物,它们没有氢醌的缺点,但具有较差的效果。
美国专利5,449,518涉及作为皮肤脱色素剂的2,5-二羟基苯基羧酸衍生物。
欧洲专利申请EP 341,664A1涉及一些作为酪氨酸酶抑制剂和皮肤脱色素剂的雷琐酚衍生物。
具有良好效果又无害的局部脱色素剂的应用对于治疗下列病况是特别希望的:黑素细胞活动过强引起的局部色素沉着过多,例如妊娠过程中出现的自发性黑斑病(妊娠面斑或褐黄斑)或雌激素-孕酮避孕继发的自发性黑斑病;良性黑素细胞机能亢进和增殖引起的局部色素沉着过多,例如老年雀斑样痣或褐黄斑;偶然的色素沉着过多,例如损伤后的感光过敏和结疤;以及某些形式的白斑病,例如白斑,其中,如果损伤的皮肤不能重新沉着色素,正常皮肤的其余部分就脱色素而使整块皮肤呈均匀的白色。
用于本发明的各种方法和组合物中的式I化合物[即,4-(2,4-二羟基苯基)环己醇]及其药物上可接受的盐适用于治疗上述皮肤病以及其它皮肤病(它们中的一些将在下文涉及),适用于这样的受治疗患者,即,为了医疗或美容而增亮皮肤或减少因病况引起的皮肤色素沉着。
4-(2,4-二羟基苯基)环己醇及其药物上可接受的盐还适用于治疗炎症(例如牛皮癣和痤疮)和用于治疗皮脂溢性皮炎。

本发明的详细描述

图解
参照图解,式(1)的化合物可通过保护可商购的4-溴雷琐酚而形成。可通过本领域技术人员熟知的常规方法引入一种合适的保护基[例如甲氧基甲基(MOM)]。例如,4-溴雷琐酚的烷基化可在二异丙胺存在下用两当量甲氧基甲基氯在卤化溶剂中在约0℃~室温下进行。
式(2)的化合物是熟知的和可商购的。式(3)的化合物可这样获得,即,在N,N,N′,N′-四甲基乙二胺存在下,将式(1)的化合物与正丁基锂在醚溶剂中反应,接着添加式(2)的化合物。式(3)的化合物在标准条件下脱水而生成式(4)的化合物,例如,在樟脑磺酸存在下,在迪安-斯达克装置内在合适的溶剂(例如甲苯)中在约110℃下加热式(3)的化合物。标准条件下的氢化(例如应用氢气和披钯木炭在乙醇中)生成式(5)的化合物。在合适的条件下去保护生成式(6)的雷琐酚。式(6)的化合物可在本领域技术人员熟知的标准条件下进一步衍生化而生成式I的雷琐酚衍生物。例如,在0℃~室温的温度下,用还原剂(例如硼氢化钠)在合适的溶剂(例如乙醇)中还原式(6)的化合物而生成式I的化合物。
式I的化合物是弱酸性的,能与各种药物上可接受的阳离子形成碱盐。这样的盐的实例包括碱金属盐和碱土金属盐,特别是钠盐和钾盐。这些盐可通过常规方法制备。用作制备本发明药物上可接受的碱盐的试剂的化学碱是与式I的化合物形成无毒碱盐的那些。这样的无毒碱盐包括那些,即,得自例如钠、钾、钙和镁等这样的药物上可接受的阳离子。这些盐可轻易地这样制备:用含有所需药物上可接受的阳离子的水溶液处理相应的酸性化合物,然后蒸发生成的溶液至干(优选在减压条件下)。也可这样制备它们:将酸性化合物的低级链烷醇溶液与所需的碱金属醇盐一起混合,然后蒸发生成的溶液至干。在任一情况下,优选应用化学计算量的试剂以便保证反应完全和所需最终产品的最大产率。

用于本发明的活性化合物还可与这样的化合物组合应用:抗坏血酸,它的衍生物,以及基于抗坏血酸的产品(例如抗坏血酸镁)或者具有抗氧化机制、促进或增强它们减少皮肤黑素和皮肤漂白作用的能力的其它产品(例如白藜芦醇)。
本发明既涉及增亮皮肤或减轻皮肤色素沉着的方法,其中,将用于本发明的活性化合物与上述一种或多种其它活性组分作为同一药物组合物的一部分一起施用;又涉及这样的方法,其中,作为合适的给药方案的部分独立施用它们,目的是获得结合治疗的益处。合适的给药方案、每次施药剂量和每种活性剂的剂量之间的具体间隔将依赖于应用的活性剂的具体组合、受治疗的患者状况以及受治疗的障碍或病况的性质和严重性。这样的另外活性组分通常将以少于或等于它们单独作为局部治疗剂的有效量的量施用。这类活性剂的FDA认可剂量(已获得FDA关于对人施药的认可)是公众可获得的。
用于本发明的活性化合物通常呈药物组合物的形式施用,它包含所述化合物与药物上可接受的载体或稀释剂。这样的组合物通常是按常规方法利用适合局部施药的固体或液体载体或稀释剂来配制的,呈溶液、凝胶、乳膏、冻胶、糊剂、洗剂、软膏、油膏等的形式。适用于本发明的活性化合物的载体实例包括:水溶液或水-醇溶液、水包油或油包水型乳状液、乳化凝胶或两相体系。优选地,本发明的组合物呈洗剂、乳膏、乳剂、凝胶、面膜、微球体或毫微球体或泡囊状分散体的形式。就泡囊状分散体来说,用于制备泡囊的脂质可以是离子型的或非离子型的,或其混合物。

2.
人初级黑素细胞中的黑素检测:
将化合物与人初级黑素细胞在α-黑素细胞刺激激素(α-MSH)存在下保温2~3天。然后用氢氧化钠和十二烷基硫酸钠(SDS)溶解细胞,在405nm处读取黑素信号。也可将14C-DOPA与酪氨酸酶抑制剂组合加到细胞中,通过闪烁计数器测定酸不溶性14C-黑素的量。IC50反映了所述化合物在通过α-MSH刺激的新黑素合成中的抑制效能。
3.
酪氨酸激酶检测(TK):
TK检测可应用c-met、erb-B2或IGF-r的纯化的酪氨酸激酶域进行。该检测中应用了抗磷酸化酪氨酸残基的特异性抗体。比色分析信号是由辣根过氧化物酶(它与抗体结合)产生的。
4.
人皮肤相当的模型:
使人黑素细胞与角质形成细胞的混合物在气-液界面生长。组织培养物形成三维结构,它在组织学和显微结构上与人表皮相似。将试验化合物加到细胞表面而模拟局部药物应用。与化合物(10μM)保温3天后,充分洗涤并溶解细胞,供DOPA氧化酶检测。
5.
IL-1检测(白细胞介素-1检测):
可应用IL-1αELISA检测(R&D体系)来评估所述化合物对人皮肤相当模型中的IL-1分泌的效果。IL-1α是促炎细胞因子,在UV引起的皮肤炎症中起作用。
6.
体内研究:
该研究中可应用皮肤颜色均匀的黑色或深棕色豚鼠。一天两次、每周5天对动物施用试验化合物的溶液(5%于乙醇∶丙二醇中,70∶30)和载体对比物达4~8周。应用该检测法,观察到了4-(2,4-二羟基苯基)环己醇使皮肤脱色素。
