Description
发明领域
本发明涉及对σ受体具有药理学活性的化合物,更具体地涉及某些1,2,3-三唑衍生物、这些化合物的制备方法、包含这些化合物的药物组合物和它们在治疗和预防σ受体介导的疾病中的用途。
发明背景
近年来,通过更好地理解与目标疾病相关的蛋白质和其它生物分子的结构已极大地帮助了对新治疗剂的搜寻。这些蛋白质中的重要一类是西格玛(σ)受体,它是可能与阿片类药物的烦躁不安、致幻作用和心脏刺激作用有关的中枢神经系统(CNS)的细胞表面受体。从σ受体的生物学和功能研究来看,已有证据表明σ受体配体可能用于治疗精神病和诸如肌张力障碍和迟发性运动障碍等的运动性失调、与亨廷顿舞蹈病或图雷特氏综合征有关的运动障碍以及帕金森氏病(Walker,J.M.et al.Pharmacological Reviews,1990,42,355)。已经报道了已知的σ受体配体林卡唑在临床上显示了在治疗精神病方面的效果(Snyder,S.H.,Largent,B.L.J.Neuropsychiatry,1989,1,7)。σ结合位点对诸如(+)SKF 10047、(+)环唑辛和(+)戊唑辛等的某些鸦片剂苯并吗啡烷的右旋异构体和诸如氟哌啶醇等的某些发作性睡病药具有优先的亲和力。
σ受体至少有两种亚型,它们可以通过这些药理学活性药物的立体选择性异构体进行甄别。SKF 10047对西格玛1(σ-1)位点有纳摩尔的亲和力,对西格玛2(σ-2)位点有微摩尔的亲和力。氟哌啶醇对两种亚型有相似的亲和力。内源性σ配体还不知道,尽管孕酮被认为是其中的一种。可能的σ位点介导的药物效应包括谷氨酸盐受体功能、神经递质响应、神经保护、行为和认知的调节(Quirion,R.et al.TrendsPharmacol.Sci.,1992,13:85-86)。大多数研究暗示σ结合位点(受体)是信号传导级联的质膜组件。已经将被报道为选择性σ配体的药物评价为抗精神病药(Hanner,M.et al.Proc.Natl.Acad.Sci.,1996,93:8072-8077)。σ受体在CNS、免疫和内分泌系统中的存在暗示其可能作为这三个系统的连接物。
考虑到σ受体激动剂或拮抗剂的潜在治疗应用,曾致力于寻找选择性的配体。因此,现有技术公开了不同的σ受体配体。
国际专利申请WO 91/09594一般性地描述了一大类σ受体配体,其中某些是在环氮原子处具有任选取代的芳基或杂芳基、烷基、烯基、炔基、烷氧基或烷氧烷基的4-苯基哌啶,四氢吡啶或哌嗪化合物。术语“芳基”和“杂芳基”通过提及一系列这样的取代基来定义。
关于本专利申请中所述化合物的化学结构,应当强调,1,2,3-三唑环体系由于其某些衍生物所显示的药理学性质及其在合成有机化学中有用而成为大量研究的主题。首先,最近的报道将1,2,3-三唑作为抗菌剂、钾通道活化剂(Calderone,V.et al.Eur.J.Med.Chem.,2005,40,521-528)。糖基和半乳糖苷的1,2,3-三唑衍生物分别被描述为糖苷酶抑制剂(Rossi,L.L.et al.,Bioorg.Med.Chem.Lett.,2005,15,3596-3599)和促乳激素-3抑制剂(Salameh,A.et al.,Bioorg.Med.Chem.Lett.,2005,15,3344-3346)。2-吡啶基-1,2,3-三唑被描述为I型转化生长因子β1受体(Kim,J.et al.,Bioorg.Med.Chem.Lett.2004,14,2401-2405)。此外,一种1,2,3-三唑-4-甲酰胺衍生物(CAI)被鉴别为在不同的人类肿瘤中具有抗血管生成和抗肿瘤转移性质的口服的可生物利用的钙流入和信号传导抑制剂(Perabo,F.G.,et al.,Anticancer Res.,2005,25,725-729)。1,2,3-三唑基团被识别为HIV-1蛋白酶抑制剂中肽基团的有效取代(Brik,J.et al.,Chembiochem,2005,6,1167-1169)。关于合成问题,1,2,3-三唑能够被看作“点击化学”的理想代表(Kolb,C.et al.,Angew.Chem.Int.Edit.,2001,40,2004-2021),最近1,2,3-三唑已被用作Bruylants反应中氰化物的更安全而实用的代替物(Prashad M.et al.,TetrahedronLett.,2005,46,5455-5458)。
然而,这些文献中均未提示这些化合物对σ受体的作用。
仍然需要寻找对σ受体具有有效的和选择性的药理学活性并具有良好“可药性”的化合物,所述可药性即与给药、分布、代谢和排泄相关的良好的药物性质。
发明概述
我们现在发现了一类结构不同的三唑衍生物,所述三唑衍生物是对σ-1受体尤其有选择性的抑制剂。所述化合物提出了1,2,3-三唑基团,其特征在于其2位被末端为胺类取代基的烷基链取代。

生物活性实施例
测试了根据上述操作合成的某些化合物作为σ-1抑制剂的活性。按照下列方案:
如(DeHaven-Hudkins et al.,1992)所述进行脑膜制备和σ-1受体结合测定,但进行了某些修改。简要地说,用Kinematica Polytron PT3000,在15000r.p.m的转速下将豚鼠的脑在10体积(重量/体积)的Tris-HCl 50mM 0.32M蔗糖、pH 7.4的溶液中均匀化30秒。将匀浆在4℃下以1000g离心分离10分钟。收集上清液并在4℃下以48000g再次离心分离15分钟。将沉淀物重新悬浮在10体积的Tris-HCl缓冲液(50mM,pH 7.4)中,在37℃下孵育30分钟,并在4℃下以48000g下离心20分钟。接着,将沉淀物重新悬浮在新鲜的Tris-HCl缓冲液(50mM,pH 7.4)中,储存在冰上直至使用。
每一测定试管含有10μL的[3H](+)-戊唑辛(终浓度为0.5nM),900μL的组织悬浮液,使最终测定体积为1mL并且最终组织浓度为约30mg组织净重/mL。通过加入终浓度为1μM的氟哌啶醇来限定非特异性结合。在用Schleicher & Schuell GF 3362玻璃纤维过滤器(预先在0.5%聚乙烯亚胺溶液中浸透至少1小时)快速过滤使反应终止前,将所有试管在37℃下孵育150分钟。然后将过滤器用4mL冷的Tris-HCl缓冲液(50mM,pH 7.4)洗涤4次。加入闪烁鸡尾酒后,使样品平衡过夜。用Wallac Winspectral 1414液体闪烁计数器,通过液闪光谱法(liquidscintillation spectrometry)测定结合的放射性的量。通过Lowry等人的方法(1951)确定蛋白质浓度。
