Abstract
本发明涉及联芳基磺酰胺及其作为例如金属蛋白酶抑制剂的用途。
Description
发明领域
本发明涉及联芳基磺酰胺及其作为例如新型金属蛋白酶抑制剂的用途。
发明背景
金属蛋白酶,包括基质金属蛋白酶和聚集蛋白聚糖酶(aggrecanase),已知在结缔组织破坏中起作用。基质金属蛋白酶(“MMP”)构成蛋白水解酶的超家族,所述蛋白水解酶是遗传相关的,能使几乎所有的限制细胞运动的细胞外基质和基底膜的成分降解。聚集蛋白聚糖酶是蛋白质ADAMTS(具有凝血栓蛋白基元的disintegrin和金属蛋白酶)家族成员。将聚集蛋白聚糖酶-1和聚集蛋白聚糖酶-2分别命名为ADAMTS-4和ADAMTS-5(Tang BL,Int J Biochem Cell Biol 2001,33,33-44)。
ADAMTS家族参与切割聚集蛋白聚糖,其是一种亦称大聚集硫酸软骨素蛋白多糖的软骨成分(Abbaszade I等人,J Biol Chem,1999,274,23443-23450),还参与原胶原加工(Colige A等人,Proc Natl Acad SciUSA 1997,94,2374-2379)、血管生成(Vazquez F等人,J Biol Chem1999,274,23349-23357)、炎症(Kuno K等人,J Biol Chem 1997,272,556-562)和肿瘤侵袭(Masui T.等人,J Biol Chem 1997,272,556-562)。已显示MMP也切割聚集蛋白聚糖。
聚集蛋白聚糖损失与关节炎疾病中的关节软骨降解有牵连,例如,骨关节炎是一种影响至少三千万美国人的致弱疾病。关节软骨的降解和产生的慢性疼痛可以严重降低生活质量。骨关节炎进程的早期和重要特征是聚集蛋白聚糖从细胞外基质的损失,导致软骨生物机制特征不足。同样,MMP和聚集蛋白聚糖酶已知在许多发生细胞外蛋白质降解或者损坏的病症中起作用,所述病症诸如癌症、哮喘、慢性阻塞性肺病(“COPD”)、动脉粥样硬化、衰老相关性黄斑变性、心肌梗死、角膜溃疡及其他眼表疾病、肝炎、主动脉瘤、肌腱炎、中枢神经系统病、异常伤口愈合、血管生成、再狭窄、肝硬化、多发性硬化、血管球性肾炎、移植物抗宿主疾病、糖尿病、炎症性肠病、休克、锥间盘变性、中风、骨质减少和牙周病。
因此需要金属蛋白酶抑制剂,包括MMP和聚集蛋白聚糖酶抑制剂。

在线路图1中,本发明的化合物以4步制备。缬氨酸甲基酯与4-溴苯磺酰氯的磺酰化在Hunig碱条件下生成磺酰胺中间体1。4-溴苯磺酰氯在Suzuki偶合条件下使用钯催化剂与硼酸酯(boronate ester)进一步偶合,生成联苯基磺酰胺中间体2。然后联苯基磺酰胺中间体2与各种烷基化试剂进行烷基化,生成联苯基磺酰胺酯(中间体3)。中间体3使用碱诸如NaOH或者LiOH进行水解,生成最终产品1。
线路图1
化合物1的另一个合成路线如线路图2所示。酚衍生物在DMF中在碱条件下转变成频哪醇硼烷(中间体4)。然后频哪醇硼烷与4-溴苯磺酰胺在Suzuki条件下偶合,生成联苯基磺酰胺中间体5,其在碱性条件下水解得到最终产品。

MMP和聚集蛋白聚糖酶可以使得各种结缔组织,包括胶原质和蛋白多糖的组分降解。在缺乏对这种活性的天然监督时,可以发生各种病理和不希望的效果。实际上,MMP和聚集蛋白聚糖酶已知在许多出现胞外蛋白质降解/损坏的病症中发挥其作用,所述病症诸如癌症、骨关节炎、类风湿性关节炎、哮喘、慢性阻塞性肺病(“COPD”)、动脉粥样硬化、衰老相关性黄斑变性、心肌梗死、角膜溃疡及其他眼表疾病、肝炎、主动脉瘤、肌腱炎、中枢神经系统病、异常伤口愈合、血管生成、再狭窄、肝硬变、多发性硬化、血管球性肾炎、移植物抗宿主疾病、糖尿病、炎症性肠病、休克、锥间盘变性、中风、骨质减少和牙周病。
优选的金属蛋白酶是聚集蛋白聚糖-1(Agg-1)。全长Agg-1的分子量是约62KD。cDNA序列含有编码837个氨基酸的2511个碱基对(Tortorella,MD等人,科学,1999,284,1664-1666)。Agg-1蛋白质可通过培养用DNA序列转化的细胞和从培养基中回收和纯化蛋白质而生成(Racie,L等人,PCT Int.Appl.)。使用标准技术诸如银染(Oaklet等人,Anal.Biochem.,1980,105,361)的SDS-PAGE丙烯酰胺(Laemmli,Nature,1970,227,680)和通过免疫印迹(Towbin等人,Proc.Natl.Acad.Sci.,USA,1979,76,4350)进行Agg-1蛋白分析。Agg-1的生物学活性可进一步表征为在检测聚集蛋白聚糖降解分子存在下的检测中所表现出的聚集蛋白聚糖蛋白水解活性的能力。这些测定方法或其进展对于本领域技术人员是公知的。这些测定方法可包括将聚集蛋白聚糖底物与聚集蛋白聚糖酶分子接触,和监测聚集蛋白聚糖片段的产生(Hughes等人,Biochem J,1995,305,799-804)。
本发明包括用于开发聚集蛋白聚糖抑制剂的方法和由此制备的抑制剂。通过化合物抑制切割萤光肽底物(Abz-TEGARGSVI-Dap(Dnp)(Abz:邻氨基苯甲酰基;Dnp:2,4-二硝基苯基)(Anaspec Inc)的能力来评价这些化合物。肽顺序TEGARGSVI以骨关节炎中的聚集蛋白聚糖的Glu373-Ala374切割位点的氨基酸顺序为基础。抑制剂与纯化的全长人重组聚集蛋白聚糖酶-1预先温育10分钟,然后在25-37℃的温度,通常在30℃加入底物。Glu-Ala键的切割自内猝灭释放荧光团。这导致在λex340nm和λex 420nm处监测到荧光增加40分钟的期间。在每个底物浓度的初速度(V)适用于以下方程式V=Vmax·Sh/(Sh0.5+Sh),其中h是Hill常数,S0.5是半数Vmax的底物浓度。在抑制剂存在时,残留活性百分比以抑制剂浓度的函数制图,IC50值通过将所述数据带入以下方程式而确定。
活性%=100 IC50/(I0+IC50)。
在二级检测方法诸如基于细胞的检测方法中,进一步分析候选分子的抑制活性。抑制剂的检测方法包括使聚集蛋白聚糖(得自软骨部分的蛋白多糖)和抑制剂的混合物与聚集蛋白聚糖酶分子接触,然后测量聚集蛋白聚糖酶抑制,例如通过检测和测量在聚集蛋白聚糖酶敏感部位通过裂解所产生的聚集蛋白聚糖片段。
因此本发明的另一个方面提供了在药物可接受载体中含有治疗有效量的聚集蛋白聚糖酶抑制剂的药物组合物。软骨中由聚集蛋白聚糖酶介导的聚集蛋白聚糖的降解与骨关节炎及其他炎性疾病有关。因此,本发明的这些组合物可用于治疗以聚集蛋白聚糖降解和/或聚集蛋白聚糖酶上调为特征的疾病。所述组合物可用于治疗这些症状或预防这些症状。
药物可接受的盐可以由以下有机和无机酸所得到的盐组成,例如乙酸、丙酸、乳酸、柠檬酸、酒石酸、琥珀酸、富马酸、马来酸、丙二酸、苦杏仁酸、苹果酸、邻苯二甲酸、氢氯酸、氢溴酸、磷酸、硝酸、硫酸、甲磺酸、萘磺酸、苯磺酸、甲基苯磺酸、樟脑磺酸和当本发明化合物含有碱性部分时类似已知的可接受酸。当本发明的化合物含有碱性部分时,也可由有机碱和无机碱形成盐,诸如碱金属盐(例如钠、锂或者钾)、碱土金属盐、铵盐、含有1-6个碳原子的烷基铵盐或者每个烷基含有1-6个碳原子的二烷基铵盐和每个烷基含有1-6个碳原子的三烷基铵盐。
