Description
发明领域
本发明主要涉及对α4β1整联蛋白与其受体如VCAM-1(血管细胞粘附分子-1)和纤连蛋白结合的抑制作用。本发明还涉及抑制这种结合的化合物、包含这种化合物的药物活性组合物和这种化合物如上所述的用途,或者用于控制或预防α4β1参与的疾病状态的制剂。
发明背景
当组织受微生物侵袭或受损时,白细胞在炎症反应中起主要作用。炎症反应最重要方面之一涉及细胞粘附过程。一般来说,白细胞通过血流循环。然而,当组织感染或受损时,白细胞识别受侵袭组织或受损组织,结合到毛细血管壁,通过毛细血管迁移到受累组织中。这些过程由称为细胞粘附分子的蛋白家族介导。
白细胞存在3种主要类型:粒细胞、单核细胞和淋巴细胞。整联蛋白α4β1(也称为极迟抗原-4,VLA-4)为单核细胞、淋巴细胞以及2种亚型粒细胞嗜酸性粒细胞和嗜碱性粒细胞表面表达的异源二聚体蛋白。该蛋白通过其识别并结合毛细血管内壁内皮细胞相关蛋白VCAM-1和纤连蛋白的能力在细胞粘附中起重要作用。
毛细血管周围组织感染或受损后,内皮细胞表达一系列粘附分子,包括VCAM-1,粘附分子对结合抵抗感染必需的白细胞很关键。结合VCAM-1或纤连蛋白之前,白细胞最初结合到某些粘附分子上,使其流动减慢并使白细胞沿活化内皮“滚动”。然后单核细胞、淋巴细胞、嗜碱性粒细胞和嗜酸性粒细胞能够通过α4β1整联蛋白牢固地与血管壁上的VCAM-1或纤连蛋白结合。有证据表明,这种相互作用还参与这些白细胞越过细胞壁迁移到受损组织中以及其最初的滚动过程。
尽管白细胞迁移到损伤部位有助于抵抗感染和破坏外源性物质,但是在许多情况下白细胞迁移可变成不可控制,血细胞大量涌入病变部位,引起广泛组织损伤。因此,能够阻断该过程的化合物可用作有益的治疗药物。所以,开发防止白细胞与VCAM-1和纤连蛋白结合的抑制剂应该是有用的。
可通过抑制α4β1结合治疗的部分疾病包括但不限于动脉硬化、类风湿性关节炎、哮喘、变态反应、多发性硬化、狼疮、炎症性肠病、移植排斥反应、接触性超敏反应和I型糖尿病。α4β1除了见于部分白细胞之外,还见于各种癌细胞,包括白血病细胞、黑素瘤细胞、淋巴瘤细胞和肉瘤细胞。已经提出涉及α4β1的细胞粘附可能参与某些癌症的转移。因此,α4β1结合抑制剂也可以用于治疗某些类型的癌症。
美国专利第5,510,332号公开了对抑制α4β1与蛋白结合的肽的分离纯化。WO95/15973、EP0 341 915、EP0 422 938 A1、美国专利第5,192,746号和WO96/06108公开了抑制结合的肽。WO96/22966、WO98/04247和WO98/04913公开了可用于抑制和防止细胞粘附和细胞粘附介导的病理的新型化合物。
所以,本发明目的之一是提供为α4β1结合抑制剂的新型化合物以及包含这种新型化合物的药用组合物。

下面利用实施例详细介绍本发明典型化合物的制备。
可使用用无机酸或有机酸产生的药学上可接受的盐形式的本发明化合物。术语“药学上可接受的盐”是指这样的盐:在合理的医药判断内适用于接触人体组织和低等动物组织而没有过度的毒性、刺激性、变态反应等,而且具有相同利益/风险比。药学上可接受的盐是本领域熟知的。例如S.M.Berge等在J.Pharmaceutical Sciences,1977,66:1等中详细介绍了药学上可接受的盐。所述盐可在本发明化合物的最后分离和纯化中原位制得或独立使游离碱官能团与合适有机酸反应制得。典型的酸加成盐包括但不限于醋酸盐、己二酸盐、藻酸盐、柠檬酸盐、门冬氨酸盐、苯甲酸盐、苯磺酸盐、硫酸氢盐、丁酸盐、樟脑酸盐、樟脑磺酸盐、二葡糖酸盐、甘油磷酸盐、半硫酸盐、庚酸盐、己酸盐、富马酸盐、盐酸盐、氢溴酸盐、氢碘酸盐、2-羟基乙磺酸盐(异硫代硫酸盐(isothionate))、乳酸盐、马来酸盐、甲磺酸盐、烟酸盐、2-萘磺酸盐、草酸盐、棕榈酸盐、果胶酯酸盐(pectinate)、过硫酸盐、3-苯基丙酸盐、苦味酸盐、新戊酸盐、丙酸盐、丁二酸盐、酒石酸盐、硫氰酸盐、磷酸盐、谷氨酸盐、碳酸氢盐、对甲苯磺酸盐和十一酸盐。此外,含碱性氮的基团可用以下物质季铵化,例如低级烷基卤如甲基、乙基、丙基和丁基氯、溴和碘;二烷基硫酸盐如二甲基、二乙基、二丁基和二戊基硫酸盐;长链卤化物如癸基、十二烷基、十四烷基和十八烷酰氯、溴和碘;芳烷基卤如苄基溴和苯乙基溴等。因此获得水溶性或油溶性或分散性产物。能够用于形成药学上可接受的酸加成盐的酸的实例包括无机酸如盐酸、氢溴酸、硫酸和磷酸和有机酸如草酸、马来酸、琥珀酸和柠檬酸。
通过使含羧酸的部分与适宜的碱例如药学上可接受的金属阳离子的氢氧化物、碳酸盐或碳酸氢盐反应或与氨或有机伯胺、仲胺或叔胺反应,在最后分离和纯化本发明化合物期间,能够原位制备碱加成盐。药学上可接受的盐包括但不局限于碱金属或碱土金属的阳离子,例如锂、钠、钾、钙、镁和铝盐等,以及无毒季铵和胺阳离子,包括铵、四甲基铵、四乙基铵、甲基铵、二甲基铵、三甲基铵、三乙基铵、二乙基铵和乙基铵等。用于形成碱加成盐的其它典型有机胺包括乙二胺、乙醇胺、二乙醇胺、哌啶、哌嗪等。

可改变本发明药用组合物中的活性成分实际剂量水平以获得有效剂量的活性化合物,实现具体患者、组合物和给药模式的需要治疗作用。所选择的剂量水平取决于具体化合物的活性、给药途径、所治疗病症的严重程度和所治疗患者的病情和过去病史。然而,本领域常规操作是所述化合物的起始剂量低于实现目的治疗作用的需要剂量,然后逐渐增加剂量直到实现需要的治疗作用。
当用于以上或其它治疗时,可使用治疗有效量的一种以下形式的本发明化合物:纯净形式或(存在这样的形式的情况下)药学上可接受的盐、酯或前体药物形式。或者所述化合物可以包含目的化合物和一或多种药学上可接受的赋形剂的药用组合物给药。术语本发明化合物的“治疗有效量”意指以适用于任何医学治疗的合适利益/风险比治疗病症的所述化合物的足够量。然而,人们知道,本发明化合物和组合物的总日用剂量由主治医师经合理的医疗判断决定。任何具体患者的具体治疗有效剂量水平取决于各种因素,包括所治疗的病症和病症的严重程度、使用的具体化合物活性、使用的具体组合物、患者的年龄、体重、一般健康状况、性别和饮食、给药时间、给药途径和所使用的具体化合物的排泄率、治疗持续时间、联合应用的药物或与所用具体化合物同时使用的的药物以及医学领域熟知的类似因素。例如本领域熟知的所述化合物的起始剂量低于实现目的治疗作用的需要剂量,然后逐渐增加剂量直到实现需要的治疗作用。
给予人或低等动物的本发明化合物总日剂量可为约0.0001至大约1000mg/kg/天。对于口服给药,更优选剂量可为约0.001至约5mg/kg/天。如果需要,有效日剂量可分成多个剂量给药;因此单剂量组合物可包含有效日剂量或其构成日剂量的分剂量。
本发明还提供包含与一种或多种无毒药学上可接受的载体一起配制的本发明化合物的药用组合物。所述药用组合物可特别配制用于口服给药的固体形式或用于胃肠外注射或直肠给药的液体形式。
本发明药用组合物可通过口服、直肠、胃肠外、脑池内、阴道内、腹膜内、局部(如以粉剂、膏剂或滴剂)、颊膜或口腔喷雾或鼻喷雾给予人和其他哺乳动物。本文使用的术语“胃肠外”指的是包括静脉、肌内、腹膜内、胸骨内、皮下和关节腔注射以及输注在内的给药模式。
另一方面,本发明提供包含本发明成分和生理学上可耐受的稀释剂的药用组合物。本发明包括一种或多种上述化合物与一种或多种无毒的生理学上可耐受或可接受的稀释剂、载体、佐剂或溶媒(本文总称为稀释剂)一起配制成的组合物,该组合物为用于胃肠外注射、鼻内给药、用于口服给药的固体形式或用于直肠给药或局部给药的液体形式等。
所述组合物也可以借助冠状内管形结构固定模(intracoronary stent)(由细线网组成的管状装置)或借助生物降解聚合物,经导管局部给予到靶部位。所述化合物也可与配基例如抗体结合用于靶向给药。
适用于胃肠外注射的组合物可包括生理学上可接受的无菌水溶液或非水溶液剂、分散剂、混悬剂或乳剂和用于复制为无菌注射溶液或分散液的无菌粉剂。适宜的水性或非水性载体、稀释剂、溶剂或溶媒的实例包括水、乙醇、多元醇(丙二醇、聚乙二醇、甘油等)、植物油(例如橄榄油)、注射有机酯例如油酸乙酯和它们的适宜混合物。
这些组合物也可包含佐剂,例如防腐剂、润湿剂、乳化剂和分散剂。例如以下各种抗菌剂和抗真菌剂能够确保防止微生物的作用:例如对羟基苯甲酸酯类、氯代丁醇、苯酚、山梨酸等。也可能需要包含等渗剂例如糖、氯化钠等。使用延迟吸收剂例如单硬脂酸铝和明胶可延迟注射药用剂型的吸收。

例如利用包衣材料如卵磷脂、如果为分散剂则维持需要的颗粒大小以及利用表面活性剂可维持合适的流动性。在某些情况下,为了延长药物的作用,需要减缓皮下注射或肌内注射的药物吸收。这可通过使用水溶性差的结晶或无定形物质的液体悬浮液来实现。那么药物的吸收速率取决于其溶出速率,而溶出速率又可能取决于晶体大小和结晶型。或者,把所述药物溶解或悬浮在油溶媒中,延迟胃肠外给予药物剂型的吸收。
通过使所述药物在生物降解聚合物例如聚交酯-聚乙醇酸交酯中形成微型包囊骨架,制备注射贮库型剂型。根据药物与聚合物的比例和所使用的具体聚合物的性质,可控制药物释放速率。其它生物降解聚合物的实例包括聚(原酸酯)和聚(酸酐)。还可将药物包埋在与机体组织匹配的脂质体或微乳中,制备贮库型注射制剂。例如通过阻留细菌的滤膜过滤或在临用前可用无菌水或其它无菌注射介质溶解或分散的无菌固体组合物中掺入杀菌剂,可使注射制剂无菌。
用于口服给药的固体剂型包括胶囊剂、片剂、丸剂、粉剂和颗粒剂。在这样的固体剂型中,活性化合物可与至少一种药学上可接受的惰性赋形剂或载体例如柠檬酸钠或磷酸二钙和/或以下任何物质混合:a)填充剂或增充剂,例如淀粉、乳糖、蔗糖、葡萄糖、甘露糖醇和硅酸;b)粘合剂,例如羧甲基纤维素、藻酸盐、明胶、聚乙烯吡咯烷酮、蔗糖和阿拉伯胶;c)湿润剂,例如甘油;d)崩解剂,例如琼脂、碳酸钙、马铃薯淀粉或木薯淀粉、藻酸、某些硅酸盐和碳酸钠;e)液体阻滞剂,例如石蜡;f)吸收促进剂,例如季铵化合物;g)润湿剂,例如单硬脂酸十六烷醇酯和单硬脂酸甘油酯;h)吸收剂,例如高岭土和膨润土粘土,以及i)润滑剂,例如滑石粉、硬脂酸钙、硬脂酸镁、固体聚乙二醇、十二烷基硫酸钠和它们的混合物。如果为胶囊剂、片剂和丸剂,所述剂型还可包含缓冲剂。
利用诸如乳糖或奶糖以及高分子量聚乙二醇等的赋形剂,相似类型的固体组合物也可用作软填充明胶胶囊和硬填充明胶胶囊的填充剂。可用包衣和壳体例如肠溶包衣和药物配制领域熟知的其它包衣剂制备片剂、糖锭剂、胶囊剂、丸剂和颗粒剂固体剂型。它们可任选包含遮光剂,而且也可以为这样的组合物:它们任选以延迟方式仅在或优选在某部分肠道释放所述活性成分。可使用的包埋成分的实例包括聚合物物质和蜡。
