另一方面,根据本发明化合物抑制VCAM-1和纤连蛋白与循环的淋巴细胞、嗜酸细胞、嗜碱细胞、和单核细胞上的VLA结合的能力,它们可被用作药物来治疗与这种结合相关的已知疾病。这种疾病的实例是类风湿性关节炎、多发性硬化症、哮喘、肠炎性疾病。本发明化合物优选被用于治疗涉及肺部炎症的疾病,如哮喘。发生哮喘的肺部炎症与嗜酸细胞浸润至肺中相关,而肺中嗜酸细胞结合到已经被某些引发哮喘的动作或物质活化的内皮细胞。

静脉,肌内,口服或吸入给药是优选的给药形式。本发明化合物给药的有效剂量取决于特定的活性成分的性质、患者的年龄和需要、以及给药方式。通过任何常规方法,例如限定剂量的临床试验可以确定剂量。因此,本发明还包括其中VCAM-1或纤连蛋白与VLA-4-表达细胞结合为疾病症状或损伤起因的疾病的治疗方法,该方法包括使用足够量的抑制VCAM-1或纤连蛋白结合VLA-4-表达细胞的本发明化合物,以便减轻所述症状或所述损伤。一般说,每天剂量约0.1-100mg/kg体重是优选的,每天剂量约1-25mg/kg体重是特别优选的,每天剂量约1-10mg/kg体重是最优选的。
本发明还涉及含有药学上有效量的本发明化合物和药学上和治疗上可接受的载体的药物组合物或药物。这种组合物可以通过任何常规方法制成制剂,即将本发明化合物与治疗上惰性载体物质一起结合制成盖仑制剂给药剂型。如果需要,可以加入一种或多种附加治疗活性物质。

口服单位剂量形式,如片剂和胶囊,优选含有25mg至1000mg本发明化合物。
本发明化合物可通过任何常规方法制备。在反应流程1中,将其中R1是H或低级烷基的式1化合物(已知化合物或可以通过标准方法制备)用能够选择性还原硝基的还原剂在苄醇的存在下处理。该方法优选在式R2-OCOX(其中X是离去基团及R2是叔烷基,苄基等)的衍生试剂存在下进行,以便形成容易离解的保护基,从而直接得到式2化合物。例如,该方法可方便地通过用Pd_的乙酸乙酯在二-叔丁基二碳酸酯的存在下催化氢化进行得到其中R2是叔丁基的衍生物2。
式3的醛的转化可通过任何一种能够使苄醇氧化为相应的醛的氧化剂例如在适当溶剂(例如二氯甲烷)中的活化的二氧化锰来实现。式3得到式5脱氢氨基酸的反应可通过用式4的Wittig试剂处理来实现,式4中R3是低级烷基及R4是烷氧基例如苄氧基-或叔丁氧基-或代表本发明化合物的酰基中的一个部分,例如取代的低级芳基。例如,用(±)-N-(苄氧羰基)-a-膦基甘氨酸三甲酯在适当的碱(例如四甲基胍)的存在下处理3直接得到式5的脱氢氨基酸,其中R3=甲基及R4=苄氧基。5至L-氨基酸6的对映有择还原反应可通过用许多适用该目的的还原剂,例如最近公开的乙基-DuPHOS铑试剂(Burk,M.J.,Feaster,J.E.;Nugent,W.A.;Harlow,R.L.《美国化学会志》(J.Am.Chem.Soc.),1993,115,10125)基本上用文献的方法来实现。
结构式6化合物转化为本发明化合物的一个方法如反应流程2所示。R2表示的保护基可在某些条件下被除去,这取决于具体的R2以及R3和R4的选择。选择这些基团将取决于具体的目标化合物。许多通用的保护基及其应用被描述在“T.W.and P.G.M.Wuts,《有机合成中的保护基》,第二版,Wiley Interscience,NewYork,1991”。例如,当R2是叔丁基及R3是低级烷基和R4是苄氧基或代表本发明化合物酰基中的一个部分,例如邻-取代的芳基时,用纯三氟乙酸或三氟乙酸的二氯甲烷溶液在适当的清除剂(例如三乙基硅烷或茴香醚)的存在下处理得到式7化合物。该化合物可以与式8羧酸用标准肽偶合条件,例如HBTU在DIPEA的极性、质子惰性溶剂如DMF的存在下及温度0℃和室温之间进行偶合得到式9化合物。在式8羧酸中,R5可以代表取代的烷基,取代的芳香环,或取代的杂芳香环。R5还可以保护的反应性功能基以使最终转化为本发明化合物。选择和使用这样的基团对于本领域技术人员来说是很清楚的。
根据R4的选择,如果酯和酸是最终合成目的,化合物9可以是本发明化合物,或如果R4是保护基(例如苄氧基),可以在适当的条件下(例如通过用Pd_在适当的溶剂中如低级醇)进行催化氢化除去保护基得到式10化合物。该中间体可以与式11羧酸用标准肽偶合条件(例如HBTU在DIPEA的极性、质子惰性溶剂如DMF的存在下及温度在0℃和室温之间)进行偶合得到式12化合物。在式11羧酸中,R6可以代表本发明化合物的一部分,例如邻-取代的芳基或杂芳基。这些化合物是已知化合物或可以通过已知方法制备。R6还可以代表适当的保护的反应性功能基,以便最终转化为本发明化合物。选择和使用这种基团对于本领域技术人员将是显而易见的。如果酸13是目标化合物,式12化合物的转化可以用适用具体选择的R3和作为R5和R6部分存在的任何功能基的标准水解条件实现。对于其中R3是低级烷基的情况,用碱金属氢氧化物,例如氢氧化锂的THF水溶液处理一般是有效的。
反应流程2
在反应流程3中,其中R7是低级烷基(其可作为保护基或作为前药中适用基团如甲基,乙基,叔丁基等)或代表与固相树脂(例如Wang树脂)的一个连接的式14化合物与式11羧酸用标准肽偶合条件(例如HBTU在DIPEA的极性、质子惰性溶剂如DMF的存在下及温度在0℃和室温之间)进行偶合得到式15化合物。15的硝基的还原可以通过用Pd_作为催化剂进行催化氢化或通过用标准还原剂(例如SnCl2)处理实现。所得结构式16化合物被用作几个系列化合物的关键中间体。在流程3的优选实例中,其可以与式8酸用标准肽偶合条件下(例如HBTU在DIPEA的极性、质子惰性溶剂如DMF的存在下及温度在0℃和室温之间)进行偶合得到式17化合物。依据R7的性质,化合物17可以是本发明化合物或者可以通过适当的水解方法被转化为本发明化合物,例如对于其中R7是低级烷基的情况,通过用过量的碱金属氢氧化物(如氢氧化锂)的醇水溶液处理进行水解。当R7表适于固相合成的树脂时,适宜的水解条件将取决于树脂的选择。对于Wang树脂的情况,用三氟乙酸在适当的清除剂的存在下处理将得到式18酸。
在特别适于固相合成的方法中,式19的N’-Alloc-氨基-Na-Fmoc保护的苯丙氨酸衍生物可以与适于固相合成的树脂(例如Wang树脂)用标准偶合方法偶合,例如与2,6-二氯苯甲酰氯形成混合酸酐并且在极性、质子惰性溶剂如N-甲基吡咯烷酮中进行偶合得到其中R7’代表该树脂的结构式20的化合物。用标准方法可以除去Alloc基团,例如用还原剂如nBu3SnH在Pd°源催化剂例如Pd(Ph3P)2Cl2的存在下处理,得到结构式21的胺衍生物。该化合物可以与式8羧酸用标准肽偶合条件(例如HBTU在DIPEA的极性、质子惰性溶剂如DMF的存在下及温度在0℃和室温之间)进行偶合得到式22化合物。Fmoc保护基可以从22中用实用肽化学中已知的标准碱处理而除去,例如用吡啶的DMF,得到式23胺。所得化合物23可以与式11羧酸用标准肽偶合条件(例如HBTU在DIPEA的极性、质子惰性溶剂如DMF的存在下及温度在0℃和室温之间)进行偶合得到式24化合物。最后结构式24化合物可以依据具体树脂选择的条件从树脂上裂解。例如对于Wang树脂的情况,用三氟乙酸的二氯甲烷在必要的清除剂的存在下处理将得到式18化合物。
根据具体合成的目标化合物,从19中除去保护基的顺序可以改变以便使Fmoc基团首先被除去,进行所得胺与式11酸的偶合接着除去Alloc基团并使产物与式8酸偶合并从树脂上裂解。还可以改变保护基的选择以便考虑树脂的反应活性或R7’的选择及R5和R6代表的任何功能基的性质。
反应流程4
从3-或4-(烷基氨基)苯丙氨酸衍生物衍生的化合物可以根据反应流程5中概括的方法制备。可以用在适当的溶剂例如乙醚中的二氮杂甲烷处理式16或7化合物分别得到其中R8是甲基的式25和26的产物。或者可以用低级烷基醛或酮,例如丙酮处理结构式16或7得到中间体Schiff碱,将其催化氢化或用氰基硼氢化钠在有机酸例如乙酸的存在下进行还原得到其中R8是低级烷基但不是甲基的式25或26化合物。化合物25或26至前药酯类27或28或至相应的酸29或30的转化可以如上述反应流程2和3中所述方法进行。
对于3-或4-磺酰氨基苯丙氨酸衍生物的制备,可以将式7,16,25或26化合物与其中R9是取代的芳基或杂芳基部分的式31的磺酰氯在惰性溶剂例如二氯甲烷中在非亲核碱例如三乙胺或吡啶的存在下在约0℃至室温下反应分别得到结构式32或33化合物,如反应流程6对于化合物7和26的说明。如果需要,用如反应流程2和3中所述一般方法将上述化合物进一步转化为式34和35化合物。
对于从3-或4-氨基甲基苯丙氨酸衍生的化合物的制备,可以使用如反应流程7中所示方法。用其中R11-R13是低级烷基或苯基的甲硅烷基化试剂例如叔丁基二甲基甲硅烷基氯在惰性溶剂例如二甲基甲酰胺中在咪唑的存在下在约0℃,处理其中R10是低级烷基的式36的3-或4-羟基甲基苯甲酸酯(已知化合物或可以根据已知方法制备)得到式37甲硅烷基保护的化合物。37的还原可以用许多适当的还原剂,例如氢化铝锂在惰性溶剂如乙醚或四氢呋喃中在温度约0℃进行还原,接着水处理得到中间体醇,可以用任一适于氧化苄基醇的氧化剂例如活化的二氧化锰将其氧化为相应的醛类得到式38醛。或者从3-或4-羟基甲基苄基醇类通过单甲硅烷基化并且分离副产物得到单甲硅烷基保护的二醇类。或者将式37酯用二异丁基氢化铝在低温例如-78℃下直接还原为式38的醛。
38至式39的脱氢氨基酸的反应可以通过用其中R3是低级烷基和R4是烷氧基(例如苄氧基或叔丁氧基)或由本发明化合物酰基代表的基团部分之一,例如邻位-取代的芳基或杂芳基的式4的Wittig试剂处理实现。例如,用(±)-N-(苄氧羰基)-a-膦基甘氨酸三甲酯在适当的碱例如四甲基胍的存在下处理38直接得到式39的脱氢氨基酸,其中R3=甲基和R4=苄氧基。39至L-氨基酸40的对映有择还原可通过用许多适用该目的的还原剂,例如最近公开的乙基-DuPHOS铑试剂还原实现。40进一步转化为本发明化合物的最佳方法将取决于R3和R4的选择,这对于本领域技术人员是显而易见的。对于其中R3是低级烷基和R4是苄氧基的情况,式41的胺的转化可方便地通过用Pd_在适当的溶剂中,例如甲醇在用作还原剂的甲酸铵存在下进行催化转移氢化。用式11羧酸酰化41可以根据上述反应流程2所述方法进行得到式42化合物。用于除去甲硅烷基保护基的反应条件将取决于具体选择的R11-R13。对于R11,R12=甲基和R13=叔丁基的情况,该基团容易通过用强酸,例如盐酸在适于选择的R3的溶剂中(例如其中R3是甲基,选择甲醇),处理而除去。
将所得式43苄基醇用类似熟知的转化方法转化为式45胺。例如将式43醇通过用甲烷磺酰氯在质子受体例如吡啶的存在下处理,接着用碱金属叠氮化物,例如叠氮化钠在极性质子惰性溶剂如二甲基甲酰胺中取代,可以转化为离去基团,例如甲磺酯。或者,从43至式44的叠氮化物的转化可以直接通过用如Thompson,A.S.Humphrey,G R.;DeMarco,A.M;Mathre,D.J.;Grabowski,E J.J.J.Org.Chem.1993,58,5886-5888中所述的联苯基磷叠氮酸酯(diphenyl phosphorazidate)处理实现。叠氮化物44至式45胺的还原可以通过许多适于叠氮化物至胺的转化的方法实现,例如通过用膦,例如三苯膦在惰性溶剂如二氯甲烷或THF中处理,接着通过水处理,或通过用适当的催化剂,例如Pd_在适于催化氢化的溶剂如低级烷醇或四氢呋喃中进行催化氢化。可将所得式45胺用适于在其它反应流程中所述游离胺类的方法转化为相应的本发明化合物。例如,45与式8羧酸在反应流程2中所述条件下偶合得到式46酰胺,如果需要,通过如反应流程2中所述碱催化水解将其进一步转化为式47酸。

对于酰亚胺,可以使用结构式53的氨基苯丙氨酸衍生物,其中R1是H或低级烷基,R6如上定义,R7”是H或容易被裂解的基团如取代的苄基,叔丁基,烯丙基等,对于前药酯是所需最终产物的情况,其使用酯基,例如乙基酯。从上述反应流程2中所述的中间体可容易获得式53化合物。式53与式54环酐在惰性溶剂(例如二氯甲烷)中反应得到开环中间体式55 。由54代表的结构式包括可以是稠合的芳香环或杂芳香环的双环分子。代替54,还可以使用能够形成双环酰亚胺的二羧酸。对于后一种情况,必须在第一步使用缩合剂,例如羰基二咪唑。用能够有效地进行环化脱氢的试剂如羰基二咪唑处理式55的化合物得到式56酰亚胺。进一步处理在式54酸酐上存在的功能基并且改变R7”功能基可以在所需化合物56上用适合酰亚胺功能基存在的标准化学方法进行以得到进一步的类似物。
对于其中R1是卤素的本发明化合物的合成,在合成期间可以将适当的卤原子插入许多点,这取决于分子中附加功能基的性质。例如可以将其中R1是氢的式6化合物用中等氯化试剂(例如N-氯琥珀酰亚胺)在质子受体例如乙酸钠的存在下处理得到其中R1是氯的式6化合物。对于从3-氨基-L-苯丙氨酸衍生的6的情况,可以保证在整个合成中在方便点分离区域异构体的混合物。在上述流程中所述其它中间体可能是用于具体目标分子的卤化的更适宜的起始原料。这些具体候选的起始原料的具体优点对于本领域技术人员是显而易见的。

不是商品的邻位取代的苯甲酸衍生物可以通过常规方法制备。例如将邻位取代的芳基碘化物或三氟甲磺酸酯在一氧化碳和适当的钯催化剂的存在下羰基化。这种碘化物或三氟甲磺酸酯中间体的制备取决于所需的具体取代基的类型,其可以通过苯胺的直接碘化或重氮化接着用碘源例如碘化钾处理获得。从相应的苯酚通过常规方法如用三氟甲磺酸酐在碱如三乙胺或二异丙基乙基胺的惰性溶剂存在下处理可以衍生三氟甲磺酸酯。获得邻位取代的苯甲酸的其它方法涉及根据Meyers,A.I.Gabel,R.,Mihelick,E.D.J.Org.Chem.,1978,43,1372-1379中所述一般方法用烷基Grignard试剂处理2-甲氧基苯基卓唑啉衍生物如75接着水解卓唑啉环得到式76酸。2-或2,6-二取代的苄腈还可以用作相应的苯甲酸的方便的前体。对于高度受阻的腈类例如2-氯-6-甲基苄腈的情况,在酸性或碱性条件下的常规水解是困难的,通过DIBAL还原相应的苯甲醛接着用铬氧化剂氧化可获得好的结果。
反应流程12
在市场上买不到的邻位取代的苯甲酸衍生物可以用常规方法制备。例如,邻位取代的芳基碘化物或三氟甲磺酸酯可以在一氧化碳和适当的钯催化剂存在下进行羰基化。该碘化物或三氟甲磺酸酯中间体的制备是与所需的具体取代形式有关,它们可以通过丙氨酸的直接碘化或重氮化之后用原料碘化物如碘化钾处理。用常规的方法如在碱(如三乙胺或二异丙基乙基胺)的隋性溶剂中用三氟甲磺酸酐处理可以从相应的酚产生三氟甲磺酸酯。邻位取代的苯甲酸的其它制备方法包括用烷基格利雅试剂处理2-甲氧基苯基唑啉衍生物如75,接着将唑啉环水解(这方法在Meyers,A.I.,GabelR.,Mihelick,B.D.J.Org.chem.1978,43,1372-1379中有说明),得到式76的酸。2-或2,6-双取代的苄腈也可作为相应的苯甲酸的前体。在高位阻腈的情况下,例如2-氯-6-甲基苄腈,在酸性或碱性条件下进行水解均较困难,而通过DIBAL还原成相应的苯甲醛接着用铬氧化剂氧化,可以得到较好的结果。
