Description
所属领域
本申请涉及含N-乙酰基-醛糖胺,N-乙酰基氨基酸,以及相关的N-乙酰基化合物的局部用组合物,及其在缓解或改善各种美容状况和皮肤病中的用途,美容状况和皮肤病包括与内在老化和/或外在老化有关的老化迹象、皮肤、指甲和头发的变化和损伤,以及由外在因素引起的变化和损伤,外在因素如日晒、辐射、空气污染、刮风、寒冷、高温、潮湿、化学品、烟尘和吸烟;以及某些与瘙痒和/或炎症有关或由其引起的皮肤病。
背景技术概述
在本申请人的U.S.专利5,091,171中描述和请求保护了采用两性组合物进行预防性和治疗性处理,以缓解美容状况和皮肤症状的方法,该组合物中含α-羟基酸、α-酮酸,羟基酸的聚合物,和相关化合物形式,以及相关的化合物。在本申请人的U.S.专利5,547,988和相关专利中,我们描述了含2-羟基羧酸或相关化合物的局部用组合物在缓解和改善皮肤状况、与内在或外在老化有关的皮肤、指甲和头发的变化中的用途。在本申请人的U.S.专利5,385,938和相关专利中,我们描述了采用含α-羟基酸、α-酮酸、羟基酸聚合物和相关化合物形式的两性组合物进行预防和治疗以缓解美容状况和皮肤病症状。在本申请人的名为"苯基-α-酰氧基链烷酸、衍生物及其治疗用途"的U.S.专利5,258,391中我们描述和请求保护了含苯基-α-酰氧基链烷酸及其衍生物的局部用组合物用于促进指甲、皮肤、唇部和其他粘膜组织角质化的用途。在本申请人的名为"添加剂增强的治疗剂的局部作用"的U.S.专利5,665,776中,我们描述和请求保护了羟基羧酸或相关化合物在增进美容成分或药物成分的美容或治疗效果中的用途。在本申请人的U.S.专利5,641,475中我们描述和请求保护了含生物活性的美容、皮肤成分或防腐剂和芳基2-乙酰氧基乙酸的局部用组合物作为协同剂或增效剂的用途。在本申请人的名为"苯基-α-酰氧基链烷酸、其衍生物及其治疗用途"的U.S.专利5,643,949中,我们描述和请求保护了含美容或皮肤用药物的局部用组合物局部用于指甲、皮肤和唇部的用途,以及一定量的苯基-α-酰氧基链烷酸可有效地促进皮肤用药物的美容或治疗效果。在U.S.专利4,603,146(Albert M.Kligman)中公开了维生素A(视黄酸)在降低和预防上皮生长及有助于皮肤恢复和保持紧致性、饱满性和弹性的用途。
在名为"局部用于光致老化的皮肤的视黄酸"(Kligman等人,美国皮肤科学杂志(J.American Academy of Dermatology),卷15,836-859,和886-887页(1986))的报告中,发现每日局部应用含0.05%视黄酸(也称为全反式视黄酸)的膏霜可改善光致老化皮肤的状况。在另一名为"局部用视黄酸改进光致老化皮肤:双盲载体对照研究"(Weiss等人美国医学协会杂志(J.American Medical Association),卷.259 527-532页(1988))的报告中述及,与仅施用载体对照样相比,每日局部应用0.1%视黄酸16周,就表现出改善光致老化皮肤的作用。副作用之一是92%参加此项研究的患者出现皮炎。皮炎的特征是分散性红斑,局部肿胀,皮肤干燥,轻度脱皮。患者苦于灼痛,麻刺感,或瘙痒。在另一名为"局部用视黄酸用于治疗老化皮肤"(Weiss等人,卷.19,169-175页(1988)的报告中描述了,局部应用0.1%视黄酸膏霜8-12个月发现对老化皮肤的症状具有临床改善作用。副作用为在眼部出现灼烧感和轻度皮肤刺激。
在名为"含N-乙酰半胱氨酸和臭味掩蔽剂的局部用组合物"的PCT申请PCT/US96/16534(1996年10月16日申请)中,公开了含0.01%-50%N-乙酰半胱氨酸或其衍生物、0.01%-0.5%臭味掩蔽剂和局部用载体的局部用组合物可改善皮肤外观。
N-乙酰半胱氨酸是经N-乙酰基化的半胱氨酸,其为含硫氨基酸,也称为α-乙酰氨基-β-巯基丙酸。含N-乙酰半胱氨酸的局部用组合物声称可改善皮肤的自然外观,包括皱纹外观。N-乙酰半胱氨酸含有游离的硫羟基,因此已知可用作抗氧剂。N-乙酰半胱氨酸作用是基于其抗氧特性。作为抗氧物质的N-乙酰半胱氨酸,也表现出预防肺氧毒性的作用欧洲呼吸学杂志(Eur.Respir.J.)2,116-126,1989)。
但N-乙酰半胱氨酸也与许多显著的缺点有关。已知N-乙酰半胱氨酸会在常规贮存环境下降解,并产生恶臭味。恶臭味说明降解过程中硫醇化合物和硫化氢的释放。由此,因其强烈的恶臭味,含N-乙酰半胱氨酸的组合物没有或基本没有商业用处。
PCT/US96/16534中称,可通过加入浓度为0.01-0.5(重量)%的某些香精化学品掩盖恶臭味。香精化学品包括:芳族酯、脂族酯、芳族醇、脂族醇、脂族酮、芳族醛、脂族醛、芳族醚和脂族醚。尽管如此,恶臭的硫醇化合物和硫化氢未经化学中和和破坏,但对于大多数用户来说,其短时遮蔽效果并非令人满意的解决之道,因此其也不是将N-乙酰半胱氨酸应用于化妆品产业的实用方法。
目前我们发现,N-醛糖胺,N-乙酰化氨基酸和相关化合物对于各种美容状况和皮肤症状均局部应用有效,包括与内在和/或外在老化有关的皮肤、指甲和头发改变的现象。N-乙酰化氨基酸和相关化合物无需含硫羟基和抗氧剂。

本发明所述的含N-乙酰基-醛糖胺,N-乙酰基氨基酸或相关的N-乙酰基化合物的组合物对各种与内在和/或外在老化、及与外在因素有关的美容状况和皮肤病均局部应用有效,这些组合物中可含有一种或多种N-乙酰基-醛糖胺,N-乙酰基氨基酸和相关的N-乙酰基化合物。在优选实施方案中,该组合物可用于与内在和/或外在老化、及与外在因素有关的皮肤、指甲和头发改变的现象。
在与老化有关的皮肤变化方面,这些变化的根本原因见于U.S.专利4,603,146(Kligman)。具体说,通过以下对表皮和真皮老化过程的概述可以说明与老化有关的皮肤变化的根本原因。
随着老化、人体受日晒和其他环境损伤的加剧,细胞呈低速分裂(更新能力降低)。它们在大小、形状和染色特性方面表现出显著的不规则性;从下到上的顺序性(极性)丧失。表皮的厚度减少(萎缩)。由于大量细胞或大群细胞而非单个细胞脱落(表皮剥落),使包含防止水分散失的隔离层和化学品渗透层的角质层异常,造成皮肤粗糙,脱皮和干燥。活上皮细胞向角化死细胞的转化并从表皮脱落的有序过程丧失,即,细胞分化受损。异常分化会造成许多异常上皮生长物病灶或肿瘤出现,最常见和主要的是光化性角化病。多年以后这些会转化成常见的皮肤癌,称为基底细胞癌和鳞状上皮细胞癌。产生色素的细胞(黑素细胞)会发生改变,形成扁平的深色生长物(色斑性黑素瘤),其会发展成为恶性黑素瘤。
构成真皮纤维的细胞会随着老化而变小和变少,一般发生在光损伤的面部皮肤中。胶原纤维的大量损失会造成皮肤松弛和易变形;弹性纤维异常,则在皮肤变形后难于迅速回复原状。由于纤维组分占皮肤体积的90%以上,其中95%是胶原,这些纤维的劣化,特别是胶原的劣化,主要会造成皮肤皱纹、松弛和丧失弹性。
此外,小血管壁会变薄,膨胀和常易破裂。血管供给会受损。
与内在老化有关的指甲和头发状况和由外在因素引起的损伤包括:头发和指甲片变细和变薄;缺乏光滑性和光泽,且头发和指甲表面不均匀;头发和指甲脆化和分叉;弹性、指甲的柔韧性、回弹性和弹性和降低。
对老化皮肤状况的常规护理是采用美容方法和医疗方法如采用苯酚,三氯乙酸,和其他化学脱皮剂,以及采用整形手术等方法。这些医疗手段成本高并有造成严重副作用的危险,并且这些治疗仅能改变皮肤的美容外观,而对内在的老化过程没有任何显著改善。
在皮肤、头发或指甲上局部涂敷本发明的组合物有益于各种与内在和/或外在老化、及与外在因素有关的皮肤、指甲和头发改变的现象,也包括具有前述特征的皮肤、指甲和头发改变。典型症状的特征有:角化紊乱,皮肤组成合成缺陷,以及与皮肤、指甲和头发老化有关的症状,这些症状包括:皮肤、指甲和头发干燥或松弛;干燥病;鳞癣;手掌和脚掌角化过度;皮肤、指甲和头发表面不均匀、粗糙;起头屑;毛囊角化病;单纯慢性苔癣;角化;痤疮;假性须疮;湿疹;牛皮癣;头疮和皮肤疮;瘙痒症;疣;疱疹;老年斑;着色斑;黑斑病;皮肤瑕疵;角化过度;皮肤色素沉着过度;胶原,糖胺聚糖,蛋白聚糖和弹性蛋白合成异常或合成减少,以及真皮中这些组分含量减少;扩张色斑;皮肤细纹;细纹;皱纹;皮肤、指甲片和头发变细和变薄;由光老化弹性组织变性引起的皮肤增厚,皮肤、指甲和头发回弹性、弹性和回复性丧失和降低;皮肤、指甲和头发缺乏润滑性和光泽;皮肤、指甲和头发颜色黯淡、外观老化;指甲和头发脆化和分叉;以及其他局部状况或症状。(ii)混合组合物
含有一种或多种N-乙酰基-醛糖胺,N-乙酰基氨基酸和相关的N-乙酰基化合物的组合物中还可含有美容、药用或其他局部用组分以促进和产生协同效果。
在本发明的该方面,本发明组合物中可含有一种或多种N-乙酰基-醛糖胺,N-乙酰基氨基酸和相关的N-乙酰基化合物,以扩大不相关的美容或药用成分的疗效。可将至少一种选自N-乙酰基-醛糖胺,N-乙酰基氨基酸和相关的N-乙酰基化合物的成分加入含美容或药用成分的局部用组合物中,该组合物可用于改善和缓解与内在和/或外在老化、及与外在因素有关的皮肤、指甲和头发改变的现象。发现加入后可达到扩大的疗效,而并非是简单的叠加疗效。
大多数药物在与靶向组织中的受体首次相互作用时产生疗效。许多药物受体是功能性大分子如酶、细胞膜成分或某些细胞成分。药物与其特定受体分子的结合亲和性或相互作用特性主要受药物化学结构的支配。由于多数药物成分与本发明的N-乙酰基化合物在化学上不同,各自的受体分子也会不同,则药理作用和疗效也不同。在该情况下,如果将N-乙酰基-醛糖胺,N-乙酰基氨基酸和/或相关的N-乙酰基化合物加入含有药物成分的组合物中,会导致以下两结果之一:
(a)对疗效无明显促进或实质性改变。在该情况下,整体临床效果是一混合效果,即药物成分产生的单独效果与N-乙酰基-醛糖胺,N-乙酰基氨基酸或相关的N-乙酰基化合物所产生的单独效果的混合。同时,药物成分及其受体分子间的相互作用不受N-乙酰基-醛糖胺,N-乙酰基氨基酸或相关的N-乙酰基化合物的存在的影响和干扰。而N-乙酰基-醛糖胺,N-乙酰基氨基酸或相关的N-乙酰基化合物也未帮助或促进药物成分与其受体分子间的结合亲和性或相互作用。该混合组合物的临床结果仅仅是混合效果。
(b)疗效增进作用或两者的治疗作用均实际丧失。在该情况下,N-乙酰基-醛糖胺,N-乙酰基氨基酸或相关的N-乙酰基化合物的存在对药物成分及其受体分子间的相互作用产生了积极或消极的影响。就积极影响而言,N-乙酰基-醛糖胺,N-乙酰基氨基酸或相关的N-乙酰基化合物会在以下方面产生增效作用:增进受体分子与药物成分的亲和性;作为更好的和更有效的辅酶,或作为破坏屏障和去除障碍以使药物与其受体分子更好结合的活化剂;例如,通过去除天然抑制剂的酶活化作用。在所有这些情况下,临床结果归因于增大的疗效,而不能从单独的疗效结果预测。
对于消极作用而言,N-乙酰基-醛糖胺,N-乙酰基氨基酸或相关的N-乙酰基化合物会干扰或降低药物成分与其受体分子的亲和性;即作为拮抗剂或抑制剂。该情况下,整体临床结果则是由于疗效的实质性减少或完全丧失,其也不是由两者单独疗效所能预测的。
我们发现在多数情况下,当将N-乙酰基-醛糖胺,N-乙酰基氨基酸或相关的N-乙酰基化合物加入组合物中时,美容和药物成分的疗效会增大,即出现上述(b)的结果。
可被N-乙酰基-醛糖胺,N-乙酰基氨基酸或相关的N-乙酰基化合物增效的美容和药物成分包括那些可改善或消除老年斑,角化和皱纹的成分;局部止痛剂和麻醉剂;抗痤疮剂;抗菌剂;抗酵母菌剂;抗真菌剂;抗病毒剂;去头屑剂;抗皮炎剂;抗组胺剂;止痒剂;止吐剂;抗晕动病剂;抗炎剂;抗过度角化剂;抑汗剂;抗牛皮癣剂;抗皮脂溢剂;头发调理剂和头发护理剂;抗老化剂和去皱剂;阻晒剂和防晒剂;皮肤增白剂;脱色剂;维生素;皮质类固醇;助晒剂;激素;视黄酸类化合物;以及其他皮肤用成分。
