Description
与相关申请的交叉参考
[0001]本申请要求2005年3月18日提交的美国临时专利申请60/662,991的优先权,将其内容通过参考引入本文。
发明背景
[0002]在口腔中,血多的疾病与细菌的作用有关。牙斑是一种软的沉积物,其作为细菌生长的副产物在牙的表面上形成。龈炎是一种牙龈和牙槽骨的炎症或感染,一般相信是由导致细菌和作为细菌的副产物形成的毒素的牙斑导致的。此外,牙斑为牙垢或牙石形成提供了场所。一般相信,牙周炎发生在没有去除的牙斑硬化成牙垢(牙石)的地方,会影响牙周膜。由于牙斑和牙石持续产生,牙龈开始退后,这可以导致持续的感染,可能会导致牙缺失。
[0003]为了预防或治疗这些疾病,人们将抗菌剂掺入到口腔护理组合物例如牙膏和漱口剂或洗剂中。在口腔中使用抗菌组合物可以延缓牙斑形成和相关的口腔感染。
[0004]在牙膏组合物中抗菌化合物的抗牙斑效力取决于很多因素,包括影响其活性的其他成分的存在。例如,当与某些阴离子表面活性剂或其他阴离子活性成分例如控制牙石的磷酸盐配制时,某些阴离子抗菌化合物和某些非离子抗菌化合物会丧失它们的效力。在很多情况中,优选使用不会与这些阴离子组分显示不利的相互作用的抗菌化合物。
[0005]厚朴(下文作“木兰”)的提取物,特别是树皮的提取物包含联苯类抗菌化合物,包括和厚朴酚和四氢和厚朴酚。当配制成例如牙膏制品时,发现该提取物具有抗菌活性。
[0006]组合物中由天然来源例如木兰制备的提取物是可变的,包含很多所制备的提取物的特定活性物以外的化合物。还没有很好地表征提取化合物的活性的模式,导致无法预测改变任意提取化合物的结构会如何影响其抗菌活性。此外,每季之间和不同地理区域的提取物的组合物也可以是不同的。结果,提取物的体内抗菌活性不是最理想的。
发明描述
[0007]一种3′,5-二取代的2,4′-二羟基-和-二烷氧基-1,1′-联苯化合物显示了对口腔内常见的各种细菌的抑制作用。这些化合物可以用作牙膏或其他口腔组合物的抗牙斑和/或抗菌组分。本发明提供了各种包含这些化合物和口腔可接受的载体的各种口腔组合物。在不同的实施方案中,抗菌和抗牙斑口腔组合物是牙膏或凝胶、牙粉、漱口剂或口腔清洗剂、锭剂、口香糖、可食用贴片等等。尽管可以使用本领域已知或发展的任意合成方法,但可以使用常规的偶合、烷化、还原和脱甲基步骤来方便地合成该抗菌化合物。
[0008]本发明提供下列结构代表的二取代的2,4′-联苯酚和衍生物:
并且不包括和厚朴酚和四氢和厚朴酚。R1和R2独立地是H或低级C1-4烷基,且R3和R4独立地是具有1到20个碳原子的烯基或烷基,条件是当R1和R2都是H时,R3和R4不都是2-丙烯基或正丙基。优选地,R包含1到8个碳原子。
[0009]所提供的抗牙斑口腔组合物包含口腔可接受的载体和抗菌有效量的至少一种结构(I)的化合物。在不同的实施方案中,该组合物包含约0.001%到约10%重量的结构(I)的化合物。不受限制地,口腔可接受的载体可以是液体载体;粉末载体;或在与口腔环境的唾液和其他组分接触即溶解的载体。在其他实施方案中,该载体可以包含香糖基质。所提供的各种组合物的形式是牙膏或凝胶、牙粉、口腔清洗剂、锭剂、口香糖和可食用贴片。组合物的其他形式包括但不限于适合涂抹到牙齿表面、晶片、擦拭物或毛巾、移植物、牙线的液体,及小哺乳动物例如狗或猫可食用或可咀嚼的形式。
[0010]在其他实施方案中,本发明提供了牙膏或凝胶组合物,所述组合物包含至少一种湿润剂,至少一种磨料材料和抗菌有效量的至少一种结构(I)的化合物。在不同的实施方案中,该牙膏或凝胶组合物还包含抗牙垢剂例如磷酸盐化合物,可替代地与合成的阴离子聚羧酸酯组合。在一个示例性的实施方案中,该牙膏或凝胶组合物包含
0.001-5%重量的化合物(I);
1-70%重量的湿润剂;
1-70%重量的磨料化合物;
0.5-2.5%重量的焦磷酸四钠(TSPP);和
1-10%重量的三聚磷酸钠(STPP)。
[0011]在其他实施方案中,本发明提供了一种在个体动物、人或非人动物的口腔中抑制细菌生长的方法,所述方法包括在患病动物的口腔表面施用包含至少一种结构(I)的化合物的抗菌组合物。在不同的实施方案中,该方法包括用包含化合物(I)的组合物刷牙和冲洗。如上所述,可以通过施用各种广泛的形式的抗菌组合物,例如牙膏、牙齿凝胶、牙粉、口腔清洗剂、凝胶上的涂料、可溶解或可食用贴片、口香糖、锭剂等等来实施该方法。在不同的实施方案中,用包含化合物(I)的抗菌组合物治疗口腔表面会导致牙斑减少或消除,预防或治疗龈炎,改善口腔恶臭,并预防牙周病。
[0012]在不同的实施方案中,该抗菌化合物选自一类下列结构表示的3′,5-二取代的-2,4′-二羟基-1,1′-联苯:
其中R3和R4独立地代表具有1到20个碳原子的烯基或烷基,条件是R3和R4不同时是2-丙烯基或正丙基。结构(II)对应于当R1和R2都是氢时的结构(I)。
[0013]在结构(I)和(II)的某些实施方案中,R3和R4都是烷基。在其他实施方案中,R3和R4都是烯基。在不同的实施方案中,基团R3和R4中的一个是烷基,另一个是烯基。在不同的实施方案中,基团R3和R4相同。在不同的实施方案中,与包含三氯生的组合物相比,包含化合物(I)和/或(II)的口腔组合物显示了相差不大的抗菌效力。
[0014]选择烷基或烯基R3和R4的大小和性质,实现需要的结构(I)和(II)的化合物的溶解度和生物利用度的组合。结构(I)和(II)的化合物是脂溶性的;该化合物在脂相和水相之间的分布可以表示为log P的值,这是本领与技术人员公知的。在不同的实施方案中,优选的logP值是3到5。一般地,基团R3和R4越大(烷基或烯基中的碳原子个数越高),在脂中中溶解度越高,在水中的溶解度越低。基团R3和R4的大小也会影响分子量,因此影响单位剂量递送的化合物(I)或(II)的摩尔量。在一个优选的实施方案中,选择基团R3和R4,以使得化合物(I)在水中的溶解度是1ppm或更大,优选5ppm或更大,更优选10ppm或更大。
[0015]可以通过本领域已知或发展的任意方法来合成上述化合物。下列方案表示的是当R1和R2是H或甲基时的实施方案中,化合物(I)和(II)的示例性合成:
将二溴中间产物(III)烷化成二甲基中间产物(IV),后者脱甲基化得到化合物(V)。反应方案中的化合物(IV)和(V)分别对应于本发明的结构(I)和(II)的实施方案。可以在例如如所述的常规格氏反应条件下烷基化该二溴中间产物。R-X表示的是烷基或烯基卤化物,R3和R4的R如上述定义,X代表卤素,优选溴。当在格氏反应中只使用卤化物时,合成其中R3和R4相同的化合物(I)和(II)的实施方案。如果需要,卤化物的混合物可以用于制备其中其中R3和R4不同的化合物(I)和(II)的实施方案。在不同的实施方案中,根据该方案所示的已知技术进行所得到的结构(IV)的完全或部分脱烷基化(显示的是完全脱烷基化),包括在-10℃下在二氯甲烷中用三溴化硼搅拌。可以容易地合成原料(III)。在一个非限制性的例子中,将对碘苯甲醚与2-甲氧苯基硼酸偶联,得到中间产物,将该中间产物溴化,形成(III)。在一个示例性的实施方案中,在磷酸四苯基钯、碳酸钾和相转移催化剂例如溴化四丁基铵存在下进行该偶联反应。在例如0℃下和Br2和二氯乙烷中进行偶联反应产物的溴化。
[0016]结构(I)和(II)的烷基和烯基化合物的其他非限制性合成途径在附图1中给出。在一个可替代的合成途径中,将二溴中间产物10与烯基溴(如在2-溴丙烯20a和丁烯基溴20b的可替代的实施方案中所示)反应,得到其中R1和R2是甲基的烯基化合物30a和30b。如所示,任选随后脱烷基化(表示为脱甲基化)成二醇50。在另一个途径中,将二溴中间产物10转化成二醛中间产物60,然后与酮(例如丙酮)进行Claissen型缩合,形成具有4个碳链的另一个中间产物70。其他的酮可以用于产生超过4个碳原子的链。然后将中间产物侧链的双键和氧基还原形成R3和R4是饱和烷基链的化合物80。可以除去烷基(如所示的甲基)形成2,4′-二羟基化合物40b。
[0017]本发明的抗菌化合物可以与口腔可接受的载体一起配制成具有例如如上所述的不同形式的口腔组合物。根据组合物的形式,口腔可接受的载体可以是液体载体、粉末载体、可溶性固体载体、香糖基质、成膜的一种或多种聚合物等等。
[0018]本发明的各种组合物包含口腔可接受的载体和抗菌有效量的化合物(I)。有效量可以是单个化合物或结构(I)表示的化合物的混合物的形式。该化合物的混合物可以是例如由故意添加分别合成的化合物形成的,或者是由添加包含基团R1、R2、R3和R4的取代型式的混合物的反应产物而形成的。
[0019]在本文中使用的“载体”涉及其中结构(I)的一种或多种化合物作为活性成分配制的抗菌个体的口腔组合物的组分。在不同的实施方案中,载体包括口腔组合物中除抗菌化合物(I)以外的所有组分。在其他方面,该术语是指组分例如非活性成分、载体、赋形物等等,本领与技术人员通常可以理解其功能为载体、填充剂或其他相对惰性的成分。换言之,术语载体是根据上下文以不同的形式使用。根据上下文,该口腔组合物除了活性化合物(I)和载体,还包括其他组分。但是,在全文中,本发明的口腔组合物的组分可以分为载体组分和抗菌化合物(I)。
[0020]为了在牙膏的情况中以非限制性的例子说明,据称载体可以是水/湿润剂系统,这构成了组合物的较大重量部分。可替代的,牙膏组合物的载体组分可以认为是水、湿润剂和抗菌系统以外的其他功能组分。无论在本文的何处,本领域技术人员将会意识到,牙膏组合物包含抗菌化合物(I)和该化合物的口腔可接受的载体。
[0021]为了进一步说明,在口腔清洗剂中,一般认为载体是抗菌化合物(I)溶解或分散于其中的水/醇液体组分。在可溶性的锭剂中,一般地理解为载体包含在口中到口的表面中缓慢溶解的固体基质物质。在口香糖中,载体包含香糖基质,而在可食用贴片中,载体包含一种或多种成膜聚合物。
[0022]在上述所有的例子中,不管是什么形式,口腔组合物都包括抗菌化合物(I),适当形式的适当载体,和产生具有所需性质的口腔组合物需要的其他的活性物或功能性物质。下面将描述其他的活性物和功能性物质。
[0023]除了生理可接受的载体,本发明的口腔组合物包含抗菌有效量的化合物(I)。在不同的实施方案中,基于口腔组合物的总重量,抗菌有效量是约0.001%到约10%,例如0.01%到约5%或约0.1%到约2%。根据口腔组合物的形式,有效量可以不同。例如,在牙膏、牙齿凝胶和牙粉中,有效量通常是至少约0.01%,更优选至少约0.05%。在一些优选的实施方案中,化合物(I)在牙膏、凝胶和粉中的存在水平是0.1%或更高,以达到抗菌活性所需的水平。一般地,化合物(I)以5%或更低,优选约2%或更低,更优选约1%或更低配制。可以考虑使用这些范围的上限,但有时处于经济上的原因较为不优选。在不同的实施方案中,最适当的活性是在约0.1%到约1%,特别是约0.1%到约0.5%或约0.1%到约0.3%时达到的,其中所有的百分比都是基于口腔组合物的总重量。在牙凝胶、牙粉、胶、可食用贴片等等中使用的量与在牙膏中的使用量相当。
[0024]在漱口剂或口腔清洗剂中,抗菌有效量的化合物(I)通常是上述范围的较低部分。典型地,化合物(I)以约0.001%(或10ppm)到最高约1%或更低的水平使用。优选地,化合物(I)为约约0.5%或更低或者约0.2%或更低。优选地,它为0.01%(100ppm)或更高。在不同的实施方案中,化合物(I)以0.03到0.12%重量存在。
