Abstract
式(Ⅰ)化合物,其中n、X、R3、R4和Ar如上所定义,可用于治疗下述疾病:关节炎、癌症、组织溃疡、再狭窄、牙周疾病、大泡性表皮松解、巩膜炎及其它以基质金属蛋白酶活性为特点的疾病、艾滋病、脓毒病、败血性休克及其它涉及TNF产物的疾病。
Description
发明背景
本发明涉及芳基磺酰氨基异羟肟酸衍生物,它们是基质金属蛋白酶或肿瘤坏死因子(下文中也称之为TNF)产物的抑制剂,并因此可用于治疗下述疾病:关节炎、癌症、组织溃疡、再狭窄、牙周疾病、大泡性表皮松解、巩膜炎及其它以基质金属蛋白酶活跃为特点的疾病、艾滋病、脓毒病、败血性休克及其它涉及TNF产物的疾病。
本发明还涉及利用这样的化合物治疗患有上述疾病的哺乳动物、特别是人的方法,以及用于这些方法的药物组合物。
有许多酶可影响结构蛋白质的离解,而且它们与金属蛋白酶结构相关。基质降解金属蛋白酶如明胶酶、溶基质素和胶原酶,与组织基质降解(例如:胶原萎陷)有关,并且牵连到许多涉及异常结绨组织和基底膜基质代谢的病理状况,如关节炎(例如骨关节炎和类风湿性关节炎)、组织溃疡(例如角膜溃疡、表皮溃疡和胃溃疡)、异常创伤愈合、牙周疾病、骨疾病(例如佩吉特症和骨质疏松症)、肿瘤转移或侵入,以及HIV感染(白血病与生物学杂志,52(2):244-248,1992)。
肿瘤坏死因子被认为与许多传染性和自身免疫性疾病有关(W.Friers,欧洲生物化学学会联合快报,1991,285,199)。
此外,研究表明TNF是在脓毒病和败血性休克中观察到的炎症反应的主要传递介质(C.E.Spooner等人,临床免疫学与免疫病理学,1992,62 S11)。

在流程1的反应2中,式VI的芳基磺酰氨基化合物,其中R16为(C1-C6)烷基、苄基、烯丙基或叔丁基,通过与下式醇的活性衍生物如氯、溴或碘衍生物,优选溴衍生物反应而转化为相应的式V化合物,其中n为1、3、4、5或6,其中R17保护基为(C1-C6)烷基、苄基、烯丙基或叔丁基。该反应是在碱如碳酸钾或氢化钠,优选氢化钠存在的条件下,在极性溶剂如二甲基甲酰胺中进行的。该反应混合物在室温下搅拌约60分钟—约48小时,优选约18小时。选择R17保护基时,要使其在R16保护基存在的情况下可选择性地去除,且不会损失R16保护基,因此R17不能与R16相同。在流程1的反应3中,从式V化合物去除R17保护基得到相应的式IV羧酸,该反应是在使用特定的R17保护基时不会影响R16保护基的适宜条件下进行的。这样的条件包括:(a)R17为(C1-C6)烷基,R16为叔丁基时的皂化作用,(b)R17为苄基,R16为叔丁基或(C1-C6)烷基时的氢解作用,(c)R17为叔丁基,R16为(C1-C6)烷基、苄基或烯丙基时用强酸如三氟乙酸或盐酸进行处理,或(d)R17为烯丙基,R16为(C1-C6)烷基、苄基或叔丁基时,在催化双(三苯基膦)氯化钯(II)存在的条件下用氢化三丁基锡和乙酸进行处理。
在流程1的反应4中,式IV的羧酸与胺、R1R2NH或它们的盐缩合得到相应的式III的酰胺化合物。若要从伯胺或仲胺或氨和羧酸开始生成酰胺化合物,可通过羧酸转化为活性官能衍生物后再与伯或仲胺或氨反应生成酰胺。该活性官能衍生物可在与伯或仲胺或氨反应前先进行分离。另一方面,羧酸可在纯的或在惰性溶剂如氯仿中,在约25℃-约80℃,优选约50℃下,用草酰氯或亚硫酰氯进行处理得到相应的酰基氯官能衍生物,然后真空蒸发去除惰性溶剂和任何存留的草酰氯或亚硫酰氯。剩余的酰基氯官能衍生物再与伯胺或仲胺或氨在惰性溶剂如二氯甲烷中进行反应生成酰胺。优选的式IV的羧酸与胺缩合得到相应的式III的酰胺化合物的方法是:用六氟磷酸(苯并三唑-1-基氧)三(二甲氨基)磷翁在碱如三乙胺存在的条件下就地处理IV得到苯并三唑-1-氧酯,它再在室温下,在惰性溶剂如二氯甲烷中,依次与胺、R1R2N反应得到式III的酰胺化合物。
在流程1的反应5中,从式III化合物去除R16保护基得到相应的式II羧酸。该反应是在对所用的特定R16保护基适宜的条件下进行的。这样的条件包括:(a)R16为低级烷基时的皂化作用,(b)R16为苄基时的氢解作用,(c)R16为叔丁基时用强酸如三氟乙酸或盐酸进行处理,或(d)R16为烯丙基时,在催化双(三苯基膦)氯化钯(II)存在的条件下用三丁基氢化锡和乙酸进行处理。
在流程1的反应6中,式II羧酸化合物在极性溶剂如二甲基甲酰胺中,用1-(3-二甲氨基丙基)-3-乙基碳化二亚胺和1-羟基苯并三唑进行处理而转化为式I的异羟肟酸化合物,约15分钟—约1小时,优选约30分钟后,向该反应混合物中加入羟胺。羟胺优选在碱如N-甲基吗啉存在的条件下从盐型式如盐酸羟胺就地制成。另一方面,羟基被保护为叔丁基、苄基或烯丙基醚的羟胺或其盐型式的被护衍生物可在六氟磷酸(苯并三唑-1-基氧)三(二甲氨基)磷翁和碱如N-甲基吗啉存在的条件下使用。可通过氢解作用去除羟胺保护基中的苄基保护基,或用强酸如三氟乙酸进行处理以去除叔丁基保护基。烯丙基保护基可通过在催化双(三苯基膦)氯化钯(II)存在的条件下用三丁基氢化锡和乙酸进行处理而除去。N,O-双(4-甲氧苄基)羟胺也可用作被保护羟胺衍生物,这时可利用甲磺酸和三氟乙酸的混合物去保护。
在流程2的反应1中,式VI的芳基磺酰氨基化合物,其中R16为(C1-C6)烷基、苄基或叔丁基,被转化为相应的式VIII化合物,其中R18为2-丙烯基或3-丁烯基。当R18为2-丙烯基时,该步骤是通过IX与2-丙烯-1-醇的活性官能衍生物如卤化物,优选碘衍生物反应而完成的;当R18为3-丁烯基时,该步骤是通过IX与3-丁烯-1-醇的活性官能衍生物如卤化物,优选碘衍生物反应而完成的,这些反应都是在碱如碳酸钾、碳酸铯或氢化钠存在下进行的,当R18为2-丙烯基时,优选氢化钠,当R18为3-丁烯基时,优选碳酸铯。该反应物在室温下,在极性溶剂如二甲基甲酰胺中搅拌约2小时-约48小时,优选约18小时。
在流程2的反应2中,式VIII化合物转化为式IV的羧酸化合物,其中n为2。R18为2-丙烯基的VIII化合物通过与甲硼烷-二甲硫化物配合物反应后立即在含水乙酸中用三氧化铬进行氧化而转化为式IV化合物,其中n为2。端烯烃氧化裂解为羧酸可通过本领域普通技术人员熟知的各种方法来完成。R18为3-丁烯基的VIII化合物氧化裂解得到式IV的羧酸化合物的优选方法是:VIII与高碘酸钠在存在于四氯化碳、乙腈和水的混合物中的催化量的氯化钌(III)存在的条件下进行反应。
按照上述流程1的反应4、5和6中所描述的方法,式IV化合物,其中n为2,进一步反应得到式I的异羟肟酸化合物,其中n为2。
在流程3的反应1中,显示了式I的异羟肟酸化合物,其中n为1而R3和R4均为氢,的合成方法,该方法是从式X的亚氨基乙酸或亚氨基乙酸的金属或铵盐与芳基磺酸化合物的官能衍生物如芳基磺酰氯,在室温下,适宜的碱如三乙胺和极性溶剂如四氢呋喃、二噁烷、水或乙腈,优选二噁烷和水的混合物中进行反应得到相应的式XI的二羧酸化合物开始的。
在流程3的反应2中,式XI的二羧酸化合物脱水得到式XII的环酐化合物。二羧酸化合物通过脱水形成环酐化合物可用多种方式来实现。优选的式XI的二羧酸化合物脱水得到式XII的环酐化合物的方法是:在约25℃-约80℃,优选约60℃下,用过量乙酸酐处理XI,通过减压蒸发去除过量乙酸酐和反应副产物乙酸后,得到式XII的环酐化合物。
在流程3的反应3中,式XII的环酐化合物在室温下与胺、NR1R2、或胺的盐如盐酸盐,在碱如三乙胺存在的条件下进行反应得到式II的羧酸,其中n为1而R1和R4均为氢。用于该反应的适宜溶剂是不会与起始物反应的那些,包括:氯仿、二氯甲烷和二甲基甲酰胺,优选二氯甲烷。
按照上述流程1的反应6中所描述的方法,式II化合物进一步反应得到式I的异羟肟酸化合物,其中n为1而R3和R4均为氢。
在流程4的反应1中,式IV的羧酸化合物,其中n为2,通过与式:(R19O)2CHN(CH3)2,其中R19为(C1-C6)烷基或叔丁基的化合物在惰性溶剂如甲苯中,在约60℃—约100℃,优选约100℃下反应约1小时—约3小时,优选2小时,从而转化为相应的式V化合物,其中R19为(C1-C6)烷基或叔丁基。在流程4的反应2中,式VI的芳基磺酰氨基化合物,其中n为1、3、4、5或6,而R16为(C1-C6)烷基、苄基、烯丙基或叔丁基,通过与下式醇的活性衍生物如氯、溴或碘衍生物,优选溴衍生物反应而转化为相应的式VIII化合物,其中R19为(C1-C6)烷基或叔丁基其中R19为(C1-C6)烷基或叔丁基。该反应是在碱如碳酸钾或氢化钠,优选氢化钠存在的条件下,在极性溶剂如二甲基甲酰胺中进行的。该反应物在室温下搅拌约60分钟—约48小时,优选约18小时。选择式IV和式VI化合物的R16保护基时,要使其在R19(C1-C6)烷基或叔丁基存在的情况下可选择性地去除,且不会损失R19(C1-C6)烷基或叔丁基,因此R16不能与R19相同。在流程4的反应3中,从式VIII化合物去除R16保护基得到相应的式XIV的羧酸,其中n为1-6,该反应是在使用特定的R16保护基时不会影响R19(C1-C6)烷基或叔丁基的适宜条件下进行的。这样的条件包括:(a)R16为(C1-C6)烷基,R19为叔丁基时的皂化作用,(b)R16为苄基,R19为叔丁基或(C1-C6)烷基时的氢解作用,(c)R16为叔丁基,R19为(C1-C6)烷基时用强酸如三氟乙酸或盐酸进行处理,或(d)R16为烯丙基,R19为(C1-C6)烷基或叔丁基时,在催化双(三苯基膦)氯化钯(11)存在的条件下用氢化三丁基锡和乙酸进行处理。
在流程4的反应4中,式XIV羧酸在极性溶剂如二甲基甲酰胺中,用1-(3-二甲氨基丙基)-3-乙基碳化二亚胺和1-羟基苯三唑进行处理而转化为式XV的异羟肟酸化合物,其中n为1-6,约15分钟—约1小时,优选约30分钟后,向该反应混合物中加入羟胺。羟胺优选在碱如N-甲基吗啉存在的条件下从盐型式如盐酸羟胺就地制成。另一方面,羟基被保护为叔丁基、苄基或烯丙基醚的羟胺或其盐型式的被护衍生物可在六氟磷酸(苯并三唑-1-基氧)三(二甲氨基)磷翁和碱如N-甲基吗啉存在的条件下使用。可通过氢解作用去除羟胺保护基中的苄基保护基,或用强酸如三氟乙酸进行处理以去除叔丁基保护基。烯丙基保护基可通过在催化双(三苯基膦)氯化钯(II)存在的条件下用三丁基氢化锡和乙酸进行处理而除去。当R19为(C1-C6)烷基时,N,O-双(4-甲氧苄基)羟胺也可用作被护羟胺衍生物,这时可利用甲磺酸和三氟乙酸的混合物进行去保护。
在流程4的反应5中,若需要的话,式XV的酰胺可通过:(a)R19为低级烷基时的皂化作用,或(b)R19为叔丁基时用强酸如三氟乙酸或盐酸进行处理而转化为相应的式XVI的羧酸化合物。
本发明酸性化合物的药学上可接受的盐是与碱形成的盐,即阳离子盐如碱金属和碱土金属盐,例如钠、锂、钾、钙、镁以及铵盐如铵、三甲基铵、二乙基铵和三-(羟甲基)-甲基铵盐。
同样诸如盐酸、甲磺酸、马来酸等的无机酸、有机羧酸和有机磺酸的盐的酸加成盐也可能提供结构的构成部分,如吡啶基这样的碱性基团。
通过下述体外分析试验显示了式I化合物或它们的药学上可接受的盐(下文中也称之为本发明化合物)对基质金属蛋白酶或肿瘤坏死因子(TNF)产物的抑制能力,因此论证了它们对以基质金属蛋白酶或肿瘤坏死因子产物为特征的疾病的治疗效力。

试验在96槽微升板和总体积250μL测试缓冲液(200mM氯化钠,50mM MES,和10mM氯化钙,pH6.0)中进行。用测试缓冲液将活性溶基质素稀释到25μg/ml。用二甲基甲酰胺将Ellmans试剂(3-羧基-4-氮苯基二硫化物)配制成1M储液,然后每槽用50μL测试缓冲液稀释到5mM,得到终浓度为1mM。
用二甲亚砜制备抑制剂的10mM储液,并用测试缓冲液连续稀释以使得向合适的槽中添加50μL该液后得到终浓度3μM、0.3μM、0.003μM和0.0003μM。所有条件下一式三份进行。
用测试缓冲液将肽底物的300mM二甲亚砜储液稀释到15mM,通过向每槽中添加50μL得到终浓度为3mM底物,由此开始试验。空白由肽底物和不含酶的Ellmans试剂构成。用分子设备UVmax板读数仪在405nm监测产物的形成。

本发明化合物或其药学上可接受的盐抑制TNF产物的能力,及因此使它们具有的治疗与TNF产物有关的疾病的效力通过下述体外试验来证明:
用单步Ficollhypaque操作技术从抗凝血的人血中分离人体单核细胞,这些单核细胞用带有二价阳离子的Hanks平衡盐溶液(HBSS)洗涤三次后,再以2×106/ml的密度悬浮于含有1%BSA的HBSS中。用Abbott CellDyn 3500分析仪测得的不同读数表明在这些制品的总细胞中有17-24%的单核细胞。
将180μ细胞悬液等分于96槽板(Costar)的板底。加入本发明化合物和LPS(终浓度100ng/ml)使终体积为200μL。所有条件下均一式三份进行。在湿润的CO2培养箱中,37℃下,培育4小时后,除去板并离心(以约250×g的速度离心10分钟)后,除去上清液,用R&D ELISA Kit测定TNFα。
当将这些药物给予人以抑制基质金属蛋白酶或肿瘤坏死因子(TNF)产物时,可使用包括口服、非胃肠道和局部给药在内的多种途径。一般来说,活性化合物口服或非胃肠道给药时的剂量为每天约0.1-25mg/kg体重,优选约0.3-5mg/kg。然而,根据所治疗患者的不同病情必须对剂量作一些调整。在任何情况下,负责给药的人应决定各患者的合适剂量。
一般来说,本发明化合物可以宽范围的不同单位剂型给药,本发明的有疗效的化合物在这样的单位剂型中的浓度为约5.0%—约70%(重量)。
对于口服给药来说,片剂中可含有各种赋形剂如微晶纤维素、柠檬酸钠、碳酸钙、磷酸二钙和甘氨酸,同时还可含有各种崩解剂如淀粉(优选玉米淀粉、土豆淀粉或木薯淀粉)、藻酸和某些复合硅酸盐,颗粒粘合剂如聚乙烯吡咯烷酮、蔗糖、明胶和阿拉伯胶。此外,通常对于片剂非常有用的是湿润剂如硬脂酸镁、十二烷基硫酸钠和滑石。类似型式的固体组合物也可用作明胶胶囊中的填充剂,在这些情况中优选的物质还包括乳糖或奶糖以及高分子量的聚乙二醇。当希望以含水悬浮液和/或酏剂口服给药时,活性成分可与各种甜味剂或调味剂、着色物质或染料结合在一起,如果需要,还可加入乳化剂和/或悬浮剂,以及象水、乙醇、丙二醇、甘油等稀释剂和它们的各种组合。
对于非胃肠道给药(肌注、腹膜注射、皮下注射和静脉注射)来说,通常制备活性成分的无菌注射液。即可用本发明治疗化合物的芝麻或花生油溶液,也可用其含水丙二醇溶液。如果需要,水溶液应进行适当的调整和缓冲,优选pH值大于8,首先要将液体稀释剂变成等渗的。这些水溶液适宜静脉注射。对于关节内注射、肌注和皮下注射来说也可用油性溶液。所有这些溶液在无菌条件下的制备易于利用本领域普通技术人员熟知的标准制药技术来完成。
利用下述实施例可进一步阐明本发明,但绝不起任何限制作用。
