Abstract
本发明涉及式I的透明质酸衍生物、它们的合成及其在有需要的受试者中作为化妆品或作为药剂的用途。
Description
技术领域
本发明涉及透明质酸衍生物和它们在医学和化妆品领域中的用途或作为饮食添加物的用途。本发明另外涉及含有这样的衍生物的药物组合物以及得到它们的方法。
背景技术
长久以来,研究人员已经已经做出了大量努力来鉴别新的组织修复医疗装置,以提供克服以前的装置的某些缺点的新工具,或者更加适用于特定组织。近十年来,所述努力甚至已经增加,也因为人们渴望简单地通过改变正常老化进程来改变他们的美学表像的需要日益增加。
公认的是,皮肤是可以被多种天然和非天然因素改变的感觉组织,所述因素诸如紫外线暴露、老化、吸烟、烧伤、痤疮、疾病等…
在健康的受试者中,组织修复或组织再生在伤害所述组织的损伤以后通过愈合过程而发生。在老化过程中,透明质酸和/或胶原在软组织中的产生减少,伴随着加速的降解速率。这样的机制会导致凹陷区(depressed area)诸如纹线、皱纹、纹理和褶皱的形成。
目前可得到的克服软组织缺陷的方法包括外科手术(例如,自体或异种移植)或涉及使用真皮填充剂的更低侵袭性技术的应用。
皮肤是由3个主要层组成的高度机化的结构,每个层具有它自身的功能。被称作表皮的外层主要由角质形成细胞组成,并且担任保护免于外界因素(诸如病原体、由紫外线引起的氧化剂应激、化学试剂的侵害)的作用,同时调节通过经表皮损失从身体释放的水的量。
中层是真皮,且是基本上由3种纤维蛋白蛋白质(即胶原、弹性蛋白和网硬蛋白)以及支持基质组成的致密弹性纤维结缔组织。所述支持基质由糖胺聚糖(即,GAG)组成,所述糖胺聚糖是能够结合大量水的长链多糖。它们一起形成不会泄漏真皮的凝胶。
最后,被称作下皮的内层是纤维脂肪层,其松散地连接至真皮,起隔断层和保护垫的作用。
真皮-表皮连接决定了皮肤的表面。因而,具有锚定结构完整性的真皮-表皮连接会维持折叠,由此增加真皮和表皮之间的接触的表面积,并促进这2种组织之间的可扩散因子的交换,从而强化它们的粘结力和改善皮肤的外观。在改变锚定结构的情况下,特别是由于胶原IV、胶原VII、层粘连蛋白V的合成的缺乏和/或由于老化或疾病,这会造成真皮-表皮连接的扁平化。实际上,已经证实,胶原IV和胶原VII在创伤愈合过程中是非常重要的(Betz P,等人,Int.J.Legal.Med.,1992,105,93)。
组织修复也涵盖了慢性创伤和/或非愈合性创伤。这样的创伤的患病率在年龄相关的疾病中、在受获得性免疫缺陷综合征(AIDS)影响的人中、或在癌症干预以后面临辐射的患者中增加。慢性创伤(诸如静脉腿溃疡)需要长期护理,且花费非常大。此外,这样的创伤经常在愈合的18个月内复发。在过去的40年中,潮湿创伤愈合的概念已经被普遍接受,从而产生了数百种不同的敷料技术,它们的目的在于改善愈合过程的时间和质量。除了传统的纱布以外,大多数目前可得到的敷料属于下述类别之一:泡沫、水胶体、水凝胶、海藻酸盐和膜;前2种代表全球潮湿创伤敷料市场的最大份额。水胶体最常见地由羧甲纤维素、明胶或果胶制成,且可以与海藻酸盐、透明质酸盐或胶原或其混合物相组合。涉及生物材料(诸如胶原、透明质酸、壳聚糖、海藻酸盐或弹性蛋白)的敷料被称作生物敷料。
由于胶原是细胞外基质(ECM)的最丰富蛋白,基于胶原的生物敷料已经被广泛地开发,但是已经逐渐被新生代的敷料替代。
已经证实,基于海藻酸盐的敷料能够促进细胞活性诸如附着和增殖(Thomas S.,J.Wound Care,2000,9,2,56;Thomas S.,J.Wound Care,2000,9,3,115;Thomas S.,J.Wound Care,2000,9,4,163)。
由于假定的成纤维细胞形成的刺激和增加的与愈合有关的早期反应,壳聚糖多糖已经被用于治疗烧伤和创伤(Paul W.,等人,Trends Biomater.Artif.Organs,2004,18,18)。
最后,存在多种含有透明质酸盐的敷料,其中透明质酸已经经过化学修饰,并同时维持它的天然的生物相容性、生物可降解性和免疫原性缺乏。透明质酸是以高浓度存在于皮肤和结缔组织中的内源多糖。在皮肤中,聚合的透明质酸可以结合水,从而形成辅助水合和充盈的粘稠物质。因此,透明质酸随着老化的损失与增加的脱水和皮肤的起皱有关。除了皮肤以外,透明质酸(即,HA)作为细胞内基质的核心组分也天然地存在于身体的不同的其它组织(诸如肌腱、肌肉、软骨和玻璃体液)中,从而使得它非常适合靶向这些组织的生物医学应用。
基于HA的生物材料敷料的例子是这样的,其中HA:
√未经过修饰,如它的钠盐(例如,ialugen,Ibsa),呈乳膏剂的形式或在含有4g ialugen的纱布垫中,用于局部施用。
√如在专利EP0216453中描述的,经由羧酸部分而完全地或部分地酯化(例如,),用于药物(例如,外科手术皮肤病学、眼科学、牙医学:Ballini A.,等人,Int.J.Med.Sci.,2009,6,2,65)或化妆品领域中。这些HA-酯可以被挤出以产生膜和纤维,被低压冻干以得到海绵状物,或通过喷雾干燥、提取和蒸发进行加工以产生微球。
√经由羟基部分而酯化(WO2004013182)。
√与其它生物活性成分连接:
o紫杉醇,以防止外科手术后的粘着形成(Jackson J.K.,等人,Pharm.Res.,2002,19,4,411;WO02090390);
o氨苄西林(GB2207142);
√与下述物质交联以形成分子网络
oα羟酸的聚合物诸如聚乳酸(WO2006069578);1,4-丁二醇二缩水甘油基醚;1,3-二胺丙烷;多功能的环氧衍生物(EP0161887);或可以
o在葡萄糖胺残基的脱乙酰化的氨基部分与葡糖醛酸部分的羧酸基团之间自交联,或在葡糖醛酸部分的羧酸基团与任何单元的羟基基团之间自交联(例如,US5676964B1,其在腹腔-骨盆外科手术以后充当保护和隔开组织的屏障,并由此避免粘着并发症)。
√沉积在膜/纱布上。
有些敷料可以进一步含有补充性的生物活性成分诸如抗生素、抗炎药、镇痛药或生长因子或它们的混合物。这样的产品的非穷尽列表中的代表可以为:它是含有3%双氯芬酸(在2.5%透明质酸中)的局部用凝胶,最近被批准用于治疗光化性角化病;或Regranex,即含有重组人血小板衍生的生长因子-BB的凝胶,目前处于III期临床试验中,用于神经病的糖尿病性溃疡。
WO2007048522公开了一种由透明质酸钠(sodium hyaluronateacid)、甘氨酸和脯氨酸和可能含有的赖氨酸和亮氨酸组成的乳膏组合物,其在快速的创伤愈合过程中可有效地促进细胞再聚合。
WO2010003797公开了具有不同分子量的基于HA的组合物,其用于治疗角膜创伤。它声称,低分子量HA级分(即,51kDa和320kDa)会增进愈合过程,同时高分子量HA级分(即,1500kDa)可能因为过于粘稠而不会促进的创伤愈合。
WO2008015249公开了由高分子量HA和多胺(例如,腐胺(putrecine))的颗粒制成的组合物,优选胶体,其用作填充剂(即,抗-皱纹填充剂或唇填充剂),用于治疗创伤愈合和用于保护人皮肤免于紫外(UVA)辐射,但是也用于保护人皮肤对抗自由基的有害作用。公开的唯一实验数据关注不同组合物的吸光度结果,因此被指示用作皮肤保护组合物。
还已经将主要由交联的HA制成的水凝胶报道为聚合基质,其可用于培养细胞(例如,形成软骨的细胞、形成骨的细胞、肌细胞、成纤维细胞和器官细胞)和将所述细胞植入特定器官中(US6129761)。
真皮填充剂是本领域众所周知,且通常由基于胶原和/或透明质酸的衍生物制成。在过去,最广泛地使用的填充剂是基于牛或人胶原,且倾向于持续3-6个月。更近的填充剂类别是基于透明质酸(HA),它们之间在HA的交联模式(即,类型和程度)、粒度和制剂方面存在差异。对这些参数中的每一种已经进行了大量研究和精细调节,以产生有目的地适合不同身体区域的填充剂。
为了克服HA不稳定性和/或容易被透明质酸酶降解,在过去的十年中出现了具有提高的半衰期的交联HA填充剂。普遍接受的是,具有低粘度的基于HA的真皮填充剂(诸如轻度交联的和/或由低分子量组成的那些)在体内的持续时间短于高度交联的和/或由高分子量HA组成的那些真皮填充剂。从高度修饰的HA衍生出的第二类填充剂通常是优选的,因为所述填充剂不需要象低粘度填充剂那样频繁地注射给患者。
已经于2003年12月得到FDA批准的第一类基于HA的交联的真皮填充剂是RestylaneTM,即它在欧洲被批准以后7年。RestylaneTM也被称作非动物的稳定化的透明质酸(NASHA),是由具有大约100万分子量的透明质酸组成的可注射填充剂,其已经与两臂交联剂(即,1,4-丁二醇二缩水甘油基醚(BDDE))交联以形成HA分子的2个羟基之间的醚交联。RestylaneTM特别适合用于矫正脸下部和眼下面的纹线以及增加唇大小。对进行的最近组织病理学研究已经证实,它会刺激胶原I和III的合成(Wang F.,等人,Arch.Dermatol.,2007,143,155)。
另一类填充剂以由Hylan B凝胶组成的Hylaform家族为代表。该家族由Hylaform Fine系、Hylaform Plus和Hylaform(Inamed Corporation,California,USA)组成,且源自使用二乙烯基砜(DVS)的交联方法,在该方法中,所述交联也通过HA的羟基而发生,从而形成HA分子之间的磺酰基-二乙基-交联。
基于HA的另一个交联的真皮填充剂家族是由不同成员(即,Juvederm 18、Juvederm 24、Juvederm 24HV和Juvederm 30)组成的Juvederm,并且是借助于BDDE(如Restylane)交联的HA产物。但是,Juvederm被宣称为均匀的凝胶形式而不是颗粒形式。它的用途是,适合用于中间至深层真皮中,用于纠正中等至严重的面部皱纹和褶皱,诸如鼻唇沟。
除了或JuvedermTM以外的、由更大的透明质酸凝胶颗粒组成的被推荐用于更深的注射。临床试验证实,的单次注射可以维持效果多达6个月。
在呈现更深陷入的面部纹线和皱痕的患者中,具有小粒度成分的制剂的应用倾向于更柔软和更光滑,并且因此非常适用于诸如唇等区域。更大的颗粒具有更多的结构,并且最适合用于深褶皱诸如鼻唇沟。
已经在老化皮肤中证实,发生胶原VII表达的减少,所述胶原VII负责将基膜锚定至真皮胶原纤维(Chen Y.Q.,等人,J.Invest.Dermatol.,1994,102,205)。最近已经发现,新的C-吡喃木糖苷衍生物会诱导糖胺聚糖和硫酸类肝素蛋白聚糖的皮肤表达(Pineau N.,等人,Eur.J.Dermatol.,2008,18,1,36)。
但是,除了由不同公司宣称的一种真皮填充剂胜过另一种真皮填充剂的所有潜在优点以外,关于所述优点的科学证据仍然存在一些疑点。根据它们的组成对不同的基于HA的真皮填充剂的优点/缺点进行对比的综述凸显了下述事实:并非所有假定的、宣称的不同填充剂的优点都经过科学地和彻底地评估(Alemman I.B.,等人,Clin.Interv.Aging,2008,3,4,629)。
最近已经公开了有包衣的透明质酸颗粒(WO2008147817)。
针注射是以最小副作用将填充剂递送进靶位置的优选方法。
在下面报告了可以将基于HA的衍生物用于制药领域中的用途的非穷举列表。
(一种由自体角质形成细胞制成的表皮自体移植物复合材料,所述角质形成细胞生长在由100%酯化的HA(即,苄酯)制成的可生物降解的基质上)已经在有利于具有慢性糖尿病足的患者的完全溃疡愈合方面表现出有前途的结果(Lobmann R.,等人,J.Diabetes Complications,2003,17,199)。
一种类似的自体移植物复合材料已经表现出对隐性营养不良性大疱性表皮松解患者的慢性皮肤溃疡创伤愈合的有益效果(Wullina U.,等人,J.Dermatol.,2001,28,4,217)。
已经证实,含有HA的凝胶(即,)的高分子量级分可用于治疗牙周病诸如牙龈炎(Jentsch H.,等人,J.Clin.Periodontol.,2003,30,2,159)。
已经证实,(一种由制成的纺织鼻敷料)会增强针对原发性慢性泪囊炎的鼻内内窥镜泪囊鼻腔吻合术的愈合过程(Wu W.,等人,Eye,2011,25,6,746),并且已经证实低压冻干的HA的乙酯可用于不同的耳病理学和用于实践耳科的、耳神经外科手术的和牙口腔医学的显微外科手术,诸如鼓膜穿孔的修复(US5503848)。
在下面报告了可以将基于HA的衍生物用于化妆品领域中的用途的非穷举列表。
唇增大,蜂窝组织,眼周的皱纹和暗圈,在眉毛和前额水平纹之间的皱纹,嘴角皱纹,由痤疮瘢痕、鼻和下巴形成的不规则,面颊、颞颥中的凹陷区,隆乳。
单独的L-肉碱或与透明质酸一起的L-肉碱在化妆品和医学领域中的应用是已知的。
US4839159公开了L-肉碱用于改善或治愈皮肤病症(包括起皱、干燥的或剥脱的皮肤)和烧伤(特别是晒伤)以及用于治愈和预防瘢痕形成(特别是由病原体感染造成)的用途。
US7854939公开了凝胶化妆品用于治疗皮肤障碍(诸如蜂窝组织和皱纹)的用途,所述凝胶由聚合物诸如羧基乙烯基聚合物(例如,聚羧乙烯)、表面活性剂和丙酰基L-肉碱甘氨酸盐酸盐的复合物制成。
US7763655公开了含有肉碱肌酸(creatinate)的局部用组合物用于抑制皮肤中的蜂窝组织形成的用途。
WO2000029030公开了透明质酸和肉碱或其具有2-20个碳原子的酰基衍生物的复合物用于化妆品(例如,美容洗剂或乳膏剂)和医学应用(例如,腿溃疡、干眼综合征)的用途。该专利申请要求保护含有重量比在1:3至3:1范围内、优选等重量比的2种组分(即,HA和肉碱或其一种酰基衍生物)的优选复合物。
尽管有大量产品可用于在医学和化妆品领域中治疗皮肤障碍,无论是从药物观点还是从化妆品观点仍然认识到的需要是,获得可用于预防或治疗皮肤障碍的新活性成分。
我们现在已经令人惊讶地发现,用肉碱或烷酰基肉碱共价地官能化的透明质酸衍生物具有可用于医学和化妆品领域中和作为饮食添加物的生物学特性。所述衍生物已经被证实会激活身体自身胶原的再生。

将16.8mg实施例2/2的聚合物溶解在3.4ml PBS中,以便得到终浓度为5mg/ml的溶液。将如此得到的溶液放入37℃水浴中。使用与在实施例4中所述相同的实验方案,通过HPLC监测释放。
在图7中报告的结果指示在生理pH时非常好的稳定性。
实施例7
为了评价本发明的药物组合物的效果,已经在全厚度皮肤模型上进行了体外生物学试验。该模型被公认为人全厚度皮肤等同物。借助于注射器,将本发明的组合物(150μl)注射进表皮和真皮之间的组织的3个不同点(即,每次注射50μl)。用未修饰的HA和仅用盐水溶液重复相同的实验方案,同时,在第4个平行实验运行中,仅用盐水溶液局部地处理组织。
膜完整性确定
通过测量细胞外培养基中的乳酸脱氢酶(LDH)的水平,确定膜完整性。实际上,LDH是一种存在于所有细胞中的稳定的细胞质酶。它在细胞外的存在的证据,必然是决定它的快速释放的细胞损伤的结果(Korzeniewski,C.,等人,J.Immunol.Methods,1983,64,313)。借助于商购可得的比色测量试剂盒(即,Cytotoxicity Detection KIT-LDH,Roche,批号1253300)进行所述确定,所述试剂盒是基于甲臢盐(λ492nm,利用在690nm的参照)的检测。收集培养物上清液,并与在试剂盒中包含的反应混合物一起在室温在暗处温育20min。死细胞或质膜受损伤的细胞的量的增加会导致培养基中的LDH酶活性的增加,所述增加与形成的甲臢的量直接相关。以前已经确定了使用8种LDH浓度的标准曲线:500mU/ml、250、125、75、62、5、31、25、15、62、7和8mU/ml。
如图1所示,任一组的LDH值不是统计上不同的,这意味着,在用本发明的组合物处理以后的良好细胞完整性证实了所述组合物的良好生物相容性。
基因表达水平的变化
为了评估用本发明的组合物注射组织的药理学作用,考虑5种不同的靶标(即,HAS1、HAS/2、COL4A1、COL7A1、SPAM1,它们分别编码透明质酸合酶-1、透明质酸合酶-2、胶原IV型α1、胶原VII型α1、透明质酸酶),运行实时PCR实验。
HAS1基因
在注射HA-CA后直到第5天,HAS1基因表达没有受到显著影响,同时未修饰的HA的注射会引起在36小时时的强烈过表达,随后在第5天快速减量调节(即,图2)。这样的行为证实,未修饰的HA会在培养基中放松效力至长期,同时证实了HA-CA会促进新HA的合成,因此能够实现更快速的愈合过程。
HAS2基因
HAS2基因表达在6h时被增量调节,此后恢复至正常水平。当使用未修饰的透明质酸替代HA-CA时,观察到类似的趋势(即,图3)。
COL7A1基因
证实了COL7A1基因表达从包含HA-CA注射的实验的第5天高度增加,同时它的水平保持对于未修饰的HA而言是明显稳定的(即,图4)。
COL4A1基因
COL4A1基因表达在6h时间点被增量调节,此后恢复至正常水平(即,36h和5天)。有趣的是观察到(即,图5),未修饰的透明质酸的注射会引起COL4A1与对照组相比在第5天的减量调节,同时在更早的时间点(即,6h)观察到由HA-CA引起的类似的增量调节。
SPAM1
未修饰的透明质酸的注射会导致SPAM1基因在第5天的强增量调节,同时HA-CA在相同时间点的作用强度低得多,并且甚至小于当使用盐水溶液时(即,图6)。
