Description
本发明涉及生物活性硅化合物,尤其是由可水解的前体起始的浓缩型生物活性硅化合物的制备方法。
硅是自然界中很普通的一种元素,一般已知的是它的天然无机形式(如二氧化硅和硅酸盐)以及它的合成聚合物形式(如聚硅氧烷)。这些含硅化合物在水介质中几乎不溶或完全不溶,这可以解释为何它们在活生物体水平出现率很低。尤其是聚硅氧烷的特征在于它对于生物介质是无活性的,因而表现出高的生物相容性。
然而,即使是很少量的硅也能起到重要的生物学作用并应被当作生命的必需元素。它对多种物种的正常生长十分必要。已阐明硅通过与糖胺聚糖和蛋白质相互作用而介入结缔组织结构。硅是这些组织细胞外基质中发现的蛋白质一糖胺聚糖复合物的组成元素之一。在软骨组织生长时硅也和糖胺聚糖相互作用。我们还知道硅在骨形成中起到重要作用,其中硅有利于矿化作用过程。
除此之外,还可认为硅是胶原的组成成分,我们认为它有胶原纤维的网状形成过程中起到重要作用。硅还参与了毛发的构造,其中硅对毛发纤维的抗性增加有特殊贡献。硅还参与细胞代谢并可能特别有利于成骨细胞的代谢活性。
除了硅的交叉连接能力及其与一些细胞代谢活性的牵连以外,组织中高硅含量与糖胺聚糖含量相连接似乎是健康而有代谢活性的组织的特征。同样地,大量研究已阐明了硅对于毛发生理循环调节的重要性。
目前的研究趋于加强硅参入大量生物学机制的想法。最新的研究甚至已阐明硅在生物系统消除铝的过程中起到重要作用。
本申请人的研究已阐明硅化合物可形成能被生物体同化的硅形式(它与矿化硅或聚硅氧烷相反),条件是它具有以低分子量的可溶性低聚体存在于水溶液中的特性。另外,水溶液中低聚体活性的另一个必需特性是可提供大量Si-OH官能团,因此很显然,如果这些生物可利用的化合物因富于Si-OH官能团的硅氧烷键Si-O-Si的链而在水溶液中形成可溶性的低聚体,它们的生物学特性才能被观察到。
目前,除了Si-OH高极性官能团的存在可赋予低聚体水溶性这一事实外,我们还认为涉及大多数上述生物学机制的化合物种类可能是式为Si(OH)4的硅酸这一可溶性硅的形式,由此事实可推导出观察到的部分特性。由于此化合物很容易缩聚形成二氧化硅,因此它在水中仅以很低的浓度存在。
随后我们通过对Si-OH官能团进行化学修饰研究了与硅酸类似但更稳定的产品。这些官能团对于生物学活性是必需的很快变得显而易见。另一方面,我们已知一系列天然化合物,其中鞣酸类和儿茶酚胺可以与硅酸形成复合物,如此即可以增加它在溶液中的溶解性。这些复合物可以成为生物体中运送硅酸的工具,此为细胞引入硅的形式。然而,对于从药物活性产品中运送硅而言它们的溶解性仍很小。
本申请人已改善了这些复合物的活性类似物,它涉及由复合分子和活性有机硅化合物之间的配合而形成的产品。这些化合物的特征是具有几个类似于硅酸的Si-OH官能团,但也有一个或两个碳-硅键。然而,即使这些具有所研究的生物学特性的类似物比硅酸复合物更加稳定,它们也必须以稀释水溶液的形式被制备,硅浓度不能超过2g/升,因为较高的硅浓度会易于发生缩聚反应。
这就是为什么本发明的主要目的是提供含有生物活性硅但不易形成无活性缩聚结构(如聚硅氧烷)的化合物的原因。
本发明的另一个目的是通过水解含硅前体并同时释放防止硅化合物缩聚的稳定化产物以进行浓缩型生物活性硅化合物的制备的方法。
其次,本发明的目的是水解前体以制备生物活性硅化合物的方法,此前体的化学式为:其中
A、B、C、D和X表示不同于OH的基团,A、B、C、D与Si原子的连键是共价键,这些键中的2个或3个是可水解的,水解在含有少量水的溶剂中进行,水与溶剂的比例优选为0.1%和5%之间,由水解硅键所得的这些化合物中的至少一个是所说的可稳定并防止由硅水解键形成聚合物的化合物。
在整个描述过程中,我们将“甲硅烷基”称作得自本发明方法的生物活性化合物,用“前体”一词表示根据本发明方法可小解的无生物活性的硅化合物。
可水解的基团是氢原子,或优选为通过氧原子、氮原子或硫原子与Si相连接的基团。因此,当硅原子直接与氧原子连接时,该基团可以是酯或烷氧基,如苯氧基的芳氧基、或烯丙氧基、或乙烯氧基。当硅通过硫原子相连接时,这些基团也可以是硫酯或芳基或烷基硫酯基,当硅与氮原子相连接时,该基团也可以是被烃链单或双取代的胺,所说烃链被一个或几个功能基团(芳基或烷基酰胺)取代或非取代。
与Si相连接且不能水解的基团可以是被一个或几个功能基团取代或非取代的烃基、具有位阻现象的某种烷氧基、碳氟基或甚至可为氟原子。
在第二种通式中,基团X可以是被一个或几个功能基团取代的烃基,它最好通过一个非水解键与硅相连接(键A或B)。
根据本发明方法的一个重要特征是前体水解发生在“温和”的条件下,也就是说在中性pH下,且不用任何化学或酶催化剂,前体在溶剂中水解,该溶剂所含的水与总体积相比仅占0.1%至5%。优选恒温下在溶剂中(含水)振荡滴加前体。溶剂可以是如乙醇、异丙醇的醇、或如环己醇或辛十二烷醇的脂肪醇、如丙二醇、丁二醇、己二醇或聚乙二醇(如:PEG 400)的二元醇,或甚至可为如丙酮或乙酸乙酯的能与水互混的有机溶剂。当水解释放酸时,建议最好加入与所用溶剂相容的化学计算量的碱,如三乙醇胺以中和水解过程中形成的酸。当水解释放碱时,最好加入化学计算量的酸。适当的酸优选为羧酸,尤其是乙酸或乳酸。
上述方法的可变换形式为首先在先前已限定的含有少量水的油状介质中使前体稳定化,然后,加入少量与油混溶的醇或二元醇,使用所得组合物以形成服浊液。
另一个必需的特征是硅原子通过至少一个可水解键与所说稳定化合物相连接。当前体根据的是第一种通式时,水解后稳定化试剂被释放到介质中,通过与甲硅烷基形成微弱的键(氢键)以稳定之,并可防止缩聚反应。
这些试剂的稳定化能力可由它们重新构成短暂共价键的能力来解释。后来我们得到了一个动态结构,其中一些键具有“混合的特征”(氢键、共价键)。当前体根据的是第二种通式时,稳定剂毫无疑问地可通过共价键与甲硅烷基保持连接。
水解后遵照上述规则的稳定剂是羟羧酸化合物,尤其是α和β羟酸、葡糖苷酸,如丝氨酸、苏氨酸或酪氨酸的羟基化或酚氨基酸、具有几个醇(或酚)官能团,重要的是具有连位醇(或酚)官能团的化合物。此种类中可举例的有:乙二醇、儿苯酚和儿苯酚胺(DOPA、肾上腺素)、聚乙二醇、如甘油的多醇、单糖(L-苏糖、L-核糖、山梨醇);如没食子酸、3,4-二羟基苯甲酸或咖啡酸的酚酸及酯化衍生物;如丙二酸的二元酸;具有适于在水介质中稳定甲硅烷基复合物的特殊几何特征的一些化合物,如环庚三烯酚酮(例如苧侧醇)。氨基酸衍生物:二甲基甲硅烷基-N-乙酰半胱氨酸
稳定剂:丝氨酸水杨酸衍生物2,2-乙氧甲基-4-氧代苯并-1,3-二氧杂-2-硅烷稳定剂:水杨酸2,2-二甲基-4-氧代苯并-1,3-二氧杂-2-硅烷稳定剂:水杨酸2,2-乙氧基、n-辛基-4-氧代苯并-1,3-二氧杂-2-硅烷稳定剂:水杨酸混杂物1,2-3,4-5,6-乙氧甲基甲硅烷基-山梨醇或三(乙氧甲基甲硅烷基)山梨醇 稳定剂:山梨醇2,3-二甲基甲硅烷氧基-N-(3-羟丙基)-3,3-丁酰胺或二甲基甲硅烷基泛酰醇 稳定剂:泛酰醇双-二甲基甲硅烷基-抗坏血酸:
稳定剂:抗坏血酸
2,2-乙氧甲基-4-氧代-5-甲基-1,3-二氧杂-2-环硅烷:
己酰基-二乙氧甲基硅烷
通常根据本发明的化合物可被用于大量需要“甲硅烷基”结构特性的应用中,也就是由抗炎症、再生、抗变性、正常化试剂、代谢促进剂、抗自由基和抗糖化所得的治疗、营养或美容用的特性,再一般地说来,即此化合物有加强生物体防御的活性。
根据本发明所得产品的益处在于它们可提供高浓度的甲硅烷基,而在不冒缩聚反应之风险时,用标准方法可能得到的最高浓度是每升水2g,使用本发明方法可能得到的甲硅烷基浓度达到每kg溶剂50g。
通过使用可提供很大配制灵活性的多种溶剂可制备甲硅烷基的浓缩溶液。它们可导致水型或半含水型的不同配方,如洗剂、滴眼液、漱口水、乳剂、凝胶、牙膏、口香糖等--。乳浊液或乳剂制品优选使用油状甲硅烷基浓缩物。当在相对较易挥发的溶剂中(丙酮、乙醇)制备浓缩甲硅烷基时,可能在较不易挥发的溶剂(如水)中配制后可以除去原有的甲硅烷基溶剂。通常可在减压下通过蒸发进行溶剂的消除。
下述实施例将阐明(而不是限制)用作药品和美容用品的配方以说明上述活性。
实施例1
再生活性毛细管膜的再构建
在本实施例中,根据本发明方法的水解前体是己酰二乙氧甲基硅烷,其M.M.=248.39(SiOH=19%),相当于Si浓度为30g/kg。
从得到甲硅烷基时起,配制受丙基-和甲基-paraben保护的Carbopol含水凝胶(通过在减压条件下蒸发以除去原来的溶剂),然后可得到活性成分浓度高达5.3%的配方。
按摩-运动治疗师通过连续按摩治疗和淋巴导液在患有上肢淋巴水肿的62个病人中试验了此凝胶。
根据水肿体积的减少所得的结果如下:
病人的数目 减少量
3 <10%
13 10-25%
29 25-50%
13 50-75%
2 75-100%
2 ≥100%
平均减少量为45%
实施例2
抗糖化的活性抗白内障滴眼液
被选作滴眼液的原始前体是二甲基-甲硅烷基-N-乙酰一半胱氨酸,其分子式为C7H13NO3SSi,M.M.=219.33,用乙醇温和水解后相当于21%的SiOH或12.7%的Si。
已配制了经脱气并含0.4%甲硅烷基的无菌溶液(减压除去乙醇),此溶液受methylparaben的保护。
这种滴眼液可用于透光性不正常的晶状体,尤其可用于老年性眼混浊。
有趣的是体外试验阐明:抗糖化现象可预防老年性白内障。
引起结缔组织硬化的因素之一是蛋白质的非酶解糖基化。已鉴定出涉及蛋白质降解的化学反应。糖与蛋白质之间的糖化(非酶解糖基化)在游离胺化蛋白位点处随机进行并形成β酮甲基胺键(Amadori产品)。后者启动了一系列化学反应,这些反应可导致蛋白质网状物的逐渐增多,不可逆键逐渐导致支撑组织特性(弹性)的丧失,这就是硬化的原因所在。
我们改善了原先用于体外研究蛋白质糖化现象中甲硅烷基特异反应性的实验步骤。
由特异于葡萄糖-蛋白质形成量的比色法可评价糖基化的程度。此技术可阐明酸水解后由糖类释放的5-羟甲基-糠醛(HMF)。通过与2-硫代巴比土酸(TBA)的比色反应可定量测定NMF-的比率。
结果,对体外试验而言,当反应开始便在蛋白质溶液中加入二甲基-甲硅烷基一半胱氨酸时,蛋白质(白蛋白)交叉连接比率以显著的方式(-37%)减小。此实验证实了由二甲基-甲硅烷基-N-乙酰基-半胱氨酸的受控水解所得的甲硅烷基明显可见的抗糖化生物学作用。
实施例3

所得n-辛基-甲硅烷基-水杨酸酯具有整容-皮肤药用活性,对于丧失的皮肤或多太阳、风、粉刺等影响的皮肤而言是必需的。

就生物活性而言,应说明的是:脂肪醇软化了角蛋白堆积物,皮肤水平释放的水杨酸起到分离它们的作用。SiOH官能团增加了水杨酸的作用,水杨酸可确保渗透量更大并可使角质细胞的代谢及其增殖正常化,炎症退化的同时伴有对脓疤的适当治愈。
实施例4
抗炎症作用口腔疗法
对于此组合物而言,使用式为C9H10O3Si、M.M.=194.26(水解后相当于24%SiOH)的2,2-二甲基-4-氧代苯并-1,3-二氧杂-2-硅烷或者式为C10H12O4Si,M.M.=224.26(水解后相当于21%SiOH)的2,2-乙氧甲基-4-氧代苯并-1,3-二氧杂-2-硅烷作为前体,配制前在适当溶剂中进行温和的水解。
已试验了几个牙龈卫生产品:漱口剂、牙膏和口香糖,参与试验的人是自内加入的。在超过70%的病例中,我们观察到所有组的牙龈都有抗炎症和再生作用,对于每天两次施用牙龈凝胶达6个多月的两个人而言,我们观察到他们牙龈收缩的减少,此病理学与骨质疏松疾病相关。
因此本实施例中使用的甲硅烷基-水杨酸酯可治疗侵害牙齿支撑组织的牙周病,并可确保良好的钙化作用。
我们观察到在使用这些化合物的所有病例中,刷牙时自动出血有所减少,牙龈的敏感性有所降低。在一个病例中观察到牙龈重新履盖了一些正在松动的牙齿,在三个病例中观察到收缩趋于稳定或减少。牙龈溶液-漱口剂

水解后所得的甲硅烷基-panthenol可以以纯化态被使用,或者以稀释于丁二醇与水(50∶50)的混合物中,根据纯产物占40%的方式被使用,这相当于Si浓度为4%,也就是说这是一个重要的量的供应。
此洗发液的配方如下:
甲硅烷基panthenol 5.00g
水/丁二醇50/50 7.50g
丙二醇 14.00g
70°的醇 100.00g
对男性皮脂溢性脱发患者试验了每天擦试施用的洗液,所试病人有23个,其中10个为15至25岁之间,11个为26至35岁之间,1个为45岁,1个为55岁。
所有病例被包括在实验中的理由是由皮脂溢性脱发决定的、被认为是非正常的脱发。在所有病例中我们观察到可见的、确定无疑的头发稀疏。
结果如下:很好的结果:59%、好的结果:9%、一般的结果:18%、无结果:14%。

实施例6
再生活性抗皱美容用组合物
已由溶解于30%的1,3-丁二醇中,相当于在溶液中提供8%SiOH(5%Si)的二甲基甲硅烷基-2-氧代-辛酸酯或乙氧甲基甲硅烷基-2-氧代-辛酸酯或2,2-乙氧甲基-4-氧代-5-甲基-1,3-二氧杂-2-环硅烷前体配制出不同的α-羟酸甲硅烷基衍生物。
也可以将一些氨基酸衍生物用作前体,如溶于60%辛基十二烷醇溶液中的且相当于施用14%SiOH的二甲基-甲硅烷基-N-乙酰一半胱氨酸(M.M.=219.33)。
水解后得到的不同甲硅烷基已被用于不同的配方中:剂量为5%至10%并可提供0.7%至1.4%的SiOH的雪花膏、乳液、凝胶或洗液。
因此,我们用1,3-丁二醇(30∶70)配制了含有7.6%甲硅烷基-2-羟基辛酸酯、相当于提供了0.50%SiOH的含水凝胶,也就是说三倍于不用本发明方法所得的相同产品的量。每天晚上在很干净的皮肤上施用此凝胶。
试验者是55至67岁的妇女,我们观察到小皱纹的减少,较深皱纹的变浅。皮肤变得更光滑、更强性和更有光泽,这一点由对老化的成纤维细胞培养物的体外试验证实。
在角质细胞和成纤维细胞单层培养物上进行细胞刺激活性实验。由中性红比色测定法测量细胞增殖,由紧外光谱测定法(540mm)进行分析,为了刺激老化细胞的试验状态,可在含有亚最适量浓度的胎牛血清(FCS)的抑制培养基中培养老化细胞。
结果:用浓缩的甲硅烷基溶液加富培养基后细胞生长以显著的方式增长。尤其是对已表现出很明显反应的成纤维细胞以及涉及胶原和弹性蛋白合成的细胞而言,对细胞刺激的反应增加了许多。我们已观察到与用2.5%FCS的对照培养物相比,对成纤维细胞增殖的动力学有200%的促进作用。
实施例7
正常化作用水合美容品组合物
在此实施例中,选择的前体是式为C15H32O9Si3,M.M.=440.67的三乙氧基-甲基甲硅烷基-山梨醇,水解后相当于31%的SiOH(16%的Si)。
使用所得的甲硅烷基-山梨醇,我们配制出液体含量为35%,掺入的甲硅烷基-山梨醇占0.5%的很纯净的水分散乳浊液。
此乳浊液已被用于脱水的干燥皮肤,从首次施药起,我们通过接触观察到很明显的浅表皮层修复。水脂薄膜在表皮/角质层水平得以修复。
Fourier Transformed I.R.光谱的体内证据已阐明加入结合水的生物学水合作用。
实施例8
抗自由基活性日用染色或非染色美容品
所用前体是式为C10H16O6Si2,M.M.=288.4的二甲基-甲硅烷基-2、3、5、6-抗坏血酸,水解后相当于32%的SiOH(19.4%的Si)。
为了给皮肤提供抗氧化现象的保护,我们配制了日用霜水分散乳浊液或者粉底霜,其中所掺入的甲硅烷基占1%。结果尽管我们有0.3%的SiOH(0.19%的Si),仍毫不怀疑产品结构水平上的修复。
在于由酶解途径(对乙醛的黄嘌呤氧化酶作用)产生氧合自由基以及当与这些自由基接触时比较用或不用甲硅烷基培养的细胞抗性的试验可体外阐明此配方的抗-自内基活性。
在细胞培养中自内基的增加可诱导细胞毒性,此毒性可导致细胞裂解并伴随有细胞乳酸脱氢酶(LDH)的增加,由紫外分光光度法测出的LDH活性剂量可得出对细胞抗自由基压力之抗性的评价。
我们已观察到所用配方的很显著效果。所用的过氧化系统产生了超氧化物离子和过氧化氢。对此结果的研究表明此配方可诱导对自发性细胞裂解的防护(LDH活性降低67%)。在经诱导的自由基压下,此防护可持续存在并清楚地增强了自身(LDH降低75%)。
