Description
技术领域
本发明涉及一类结构新颖的异吲哚啉类化合物,其药学上可接受的盐、溶剂合物、药物组合物 及其在制备治疗或预防多种疾病的药物中的应用。
背景技术
细胞内蛋白质表达的严密调控在细胞行使功能、细胞存活以及分裂过程中发挥着重要作用,许 多原发性或获得性疾病通常涉及蛋白质功能异常。传统的调节蛋白功能异常的方法主要是过设计靶 向抑制剂或激动剂,这些靶向药物在疾病的治疗中发挥着重要作用。尽管如此,为了获得满意的疗 效,这些抑制剂或激动剂通常需要维持在较高的药物浓度以达到有效治疗效果,这也在一定程度上 导致了药物的不良反应。另一种调节蛋白质功能异常的方法是改变病理相关蛋白的动态平衡,蛋白 质的动态平衡包括蛋白质的合成和降解,例如可以利用小干扰RNA(siRNA)、反义寡聚核苷酸或基 因编辑技术来敲除或沉默靶蛋白基因,这些基于核酸的技术通过作用于靶蛋白的转录和翻译过程而 改变蛋白质的合成,该类技术最大的局限在于核酸的体内稳定性以及生物利用度较低,进而在一定 程度上限制了其应用。另一种调节蛋白质动态平衡的策略是调控蛋白质的降解过程,通过促进或抑 制蛋白质的降解可以直接改变靶蛋白在细胞内的表达量。泛素-蛋白酶体系统(UPS)在蛋白质的降 解过程中发挥重要作用,在一系列泛素化酶的作用下,靶蛋白可以被泛素化标记,带有特殊泛素标 签的蛋白质可以被运送至蛋白酶体并被其降解。
蛋白质的泛素化过程是一个串联的多步反应过程,主要有三类酶参与:E1泛素激活酶,E2 泛素结合酶,E3泛素连接酶。根据E3泛素连接酶的保守结构域和作用模式可以将其分成三大类, 其中TECT家族和RBR家族E3泛素连接酶在底物泛素化过程中需要先将泛素从E2泛素激活酶上 转移至自身,再将泛素从E3泛素连接酶上转移至底物蛋白上。相比较而言,RING家族E3泛素连 接酶在整个E3泛素连接酶中占据较大比例,这类E3泛素连接酶上含有RING结构域或RING样 结构域,它们能够与E2泛素结合酶结合,促进泛素直接从E2泛素结合酶直接转移至底物蛋白上。 CRL4CRBNE3泛素连接酶属于RING家族E3泛素连接酶,它是一种由多个亚基组装而成的蛋白复 合物,整个复合物包含底物蛋白识别模块(CRBN)、E2泛素结合酶识别模块(RING结构域)以 及二者之间的连接部分(Cullin蛋白)。CRBN在整个蛋白复合物中直接结合底物,控制着整个泛 素化过程的底物特异性。
直接作用于CRBN的小分子调节剂可以控制CRL4CRBNE3泛素连接酶的底物选择性。新的研 究发现,Cereblon(基因名:CRBN)是免疫调节剂—沙利度胺及其类似物的直接靶点(Science,2010, 327,1345;Science,2014,343,301;Science,2014,343,305;Nature,2015,523,183.)。研究证明度 胺类免疫调节剂在多发性骨髓瘤细胞系中,通过调控CRBN-泛素连接酶复合物的活性,选择性诱 导转录因子IKZF1和IKZF3进行泛素化并降解,这一过程改变了T细胞和B细胞的功能,同 时对多发性骨髓瘤细胞产生毒性效应,由此达到治疗多发性骨髓瘤在内的恶性髓系肿瘤的作用。 最近的研究表明,来那度胺,一种沙利度胺的类似物,能够通过CRL4CRBNE3泛素连接酶选择性诱 导CK1α的泛素化并降解,实现治疗5q缺失型骨髓异常性增生综合征(MDS),而沙利度胺的另 一种结构类似物(CC-885)则能够通过作用于CRL4CRBNE3泛素连接酶选择性诱导并降解GSPT1, 对多种肿瘤细胞展现出很强的细胞毒性。
现有研究结果表明:不同度胺类药物分子与靶点CRBN相互作用后,具有不同底物蛋白降解 特异性。如来那度胺在治疗多发性骨髓瘤时,其疗效主要是通过选择性降解IKZF1和IKZF3实现; 而在治疗5q缺失的骨髓异常性增生综合症(del(5q)MDS)时主要通过降解CK1α达到治疗效果。 由于目前发展的度胺类似物中主要是来那度胺对CK1α表现出较强的降解活性,因此是最主要的临 床有效的治疗骨髓异常性增生综合征del(5q)MDS的度胺类药物。FDA批准的沙利度胺用于治疗 麻风结节性红斑,来那度胺临床实验中用于治疗前列腺癌,泊马度胺临床实验中用于治疗骨髓纤维 化症。随着新的度胺类药物的研发和临床实验的开展,度胺类药物分子的适应症也在不断扩展中, 在临床试验中,来那度胺可单独或与其它治疗剂联合用药,用于多种癌症、疼痛、中枢神经系统疾 病和免疫系统相关的疾病治疗(见WO2012/015986)。
来那度胺、泊马度胺、CC-122、CC-220、CC-885这些已经报化合物的结构与沙利度相似,该 类化合物的特点在于,结构上的改变和调整后,化合物具有不同的药理活性和完全不同的治疗效果, 进而在临床上可用于治疗不同的适应症。
WO2008115516A2、US8153659B2、US9181216B2、US9920027B2公开了通式为S1所代表的 化合物:
WO2011100380 A1、CN102822165B,公开了一类通式为S2所代表的化合物:

WO2008027542A2、US8877780B2、US9447070B2公开了一类通式为S3所代表的化合物:
通式S6、S7中代表性的化合物为:
来那度胺及上述部分分子的作用机制是:不同结构的化合物能够和CRBN结合,引起CRBN 结合部分构象的改变,从而招募不同的内源性生物大分子与CRBN的结合;进而对潜在不同的内 源性底物蛋白进行泛素化并降解,因而能够产生不同的药理活性,在临床实验中用于治疗不同的适 应症。
综上所述,来那度胺主要用于治疗治疗多发性骨髓瘤和骨髓异常增生综合征,对其他适应症效 果并不理想;其他上述提到的化合物如CC-122,CC-885和CC-220尚处于临床前或临床研究中。 因此,开发结构新颖的化合物作为CRL4CRBNE3泛素连接酶调节剂,可以实现进一步提高肿瘤的治 疗效果治疗和扩展度胺类药物的新适应症的临床上的需求;结构不同的度胺类分子的药理学活性和 药物学性质都不为人所知,各方面的性质和作用都具有不确定性。基于度胺类分子的作用机制,开 发新结构的度胺类分子,能够实现招募新的蛋白底物,进而实现的治疗效果的提高和新适应症的扩 展。因此,继续开发新颖结构的CRL4CRBNE3泛素连接酶调节剂以拓展新的适应症具有非常重要研 究价值和现实意义。
发明内容
本发明的发明人通过对CRL4CRBNE3泛素连接酶与小分子作用的复合物晶体结构(PDB ID: 4CI2、5HXB)进行分析获得下述重要信息:CRL4CRBNE3泛素连接酶与小分子存在多个结合口袋, 因此可以发展结构复杂的多个结合位点的小分子,实现CRL4CRBNE3泛素连接酶与小分子的有效结 合。同时利用分子动力学模拟方法对模型分子和E3泛素连接酶界面进行结构动态和结合位点分析, 结合分子对接和基于复合物的药效团匹配策略,通过打分函数对化合物在E3泛素连接酶活性位点 的结合模式、相互作用进行评价及结构设计上的计算模拟和优化,获得新型特异性的CRL4CRBNE3 泛素连接酶小分子调节剂。基于这些信息,我们设计并合成一系列本申请所述的CRL4CRBNE3泛素 连接酶的小分子调节剂,并测试了化合物的活性。部分代表性的化合物在多发性骨髓瘤细胞系 (MM.1S)、套细胞淋巴瘤细胞系(Mino)、急性髓系白血病细胞系(MV-4-11)中测试结果表明, 新型的小分子调节剂具有非常高的细胞的生长抑制活性,该分子作用于生物体后,通过调节生物体 内泛素—蛋白酶体介导的蛋白降解途径,可以调控底物蛋白的降解,进而实现基于CRBN靶点的 有效的疾病治疗。

本发明中所用术语“同位素化合物”是指本发明的通式(I)化合物、其药学上可接受的盐、溶剂化 物、立体异构体、代谢物,或前药中含有一个或多个天然或非天然丰度的原子同位素。本发明也涵 盖经同位素标记的本发明化合物,除了一个或多个原子是被原子质量或质量数不同于自然中常见 的原子质量或质量数之一原子所置换的事实之外,其是与此述者相同。可纳入本发明的化合物中 的同位素实例,包括氢、碳、氮、氧、磷、硫、氟、碘及氯之同位素,其分别诸如:2氢、3氢、 11碳、13碳、14碳、13氮、15氮、15氧、17氧、18氧、31磷、32磷、35硫、18氟、123碘、125碘及36氯。
某些同位素标记的本发明的化合物(例如用3H和14C标记的那些)用于化合物和/或底物组织 分布试验。特别优选氚化(即3H)和碳-14(即14C)同位素,因为它们容易制备和检测。而且,较重 的同位素如氘(即2H)进行取代可以提供由较大的代谢稳定性导致的某些治疗优点(例如体内半 衰期增加或剂量需求减小),因而在某些情况下可能是优选的。正电子发射同位素,例如15O、13N、 11C和18F用于正电子发射体层摄影术(PET)研究,以检查底物受体占用率。同位素标记的本发 明的化合物一般可以遵循类似于在方案和/或下文实施例中所公开的方法,通过用同位素标记的试 剂替代非同位素标记的试剂来制备。本发明的化合物的所有同位素变体,无论是否具有放射性,都 包括在本发明的范围内。
本发明中可以氘代的化合物位置可以在多个不同的位置进行氘代,氘代的位置有如下形式,但 不限制于以下形式:
在本发明中,除非特别指出,所用术语具有本领域技术人员公知的一般含义。

8.化合物与CRBN相互作用验证实验
研究证明来那度胺免疫调节剂在血液肿瘤细胞系中,通过与CRBN结合进而调控CRBN-泛素 连接酶复合物的活性,选择性诱导转录因子IKZF1和IKZF3进行泛素化并降解,由此达到治疗 恶性血液肿瘤的作用(Science,2014,343,301;Science,2014,343,305;Nature,2015,523,183.)。通 过利用高效亲和磁性纳米粒子“FG beads”,在磁珠上预先连接沙利度胺的类似物,该连接沙利度胺 的磁珠(Thalidomide FG beads)可以钓取CRBN蛋白(Leukemia,2012,26,2326;Science,2010, 327,1345)。本实验中通过NP-400细胞裂解液裂解血液肿瘤Mino细胞,离心获得澄清细胞裂解 液后均匀分成三个样品,在这个三个样品中分别加入Thalidomide FG beads,将Thalidomide FG beads与细胞裂解液在4℃孵育6小时,孵育完成后用磁力架分离磁珠,用NP-400裂解液重悬分离, 重复3次,获得去除多余细胞裂解液的磁珠。三组磁珠样品分别用含有DMSO的NP-400裂解液(对 照组)、含500mM实施例化合物17的NP-400裂解液、含1mM来那度胺的NP-400裂解液,于 25℃孵育15分钟;洗脱两次后合并获得洗脱液,将该洗脱液用SDS Loading Buffer加热变性,通 过Westernblotting用CRBN的抗体(Proteintech)检测每个样品中CRBN的量。实验结果如下图 1。
通过上述实验结果可以发现,实施例化合物17能将CRBN从与沙利度胺结合的磁珠上洗脱下 来,分别与DMSO组和阳性化合物来那度胺组对照,其作用原理与来那度胺类似,而只用DMSO 不能竞争CRBN与沙利度胺的结合。因此,实施例化合与CRBN具有很好的作用能力。因此,本 发明中的实施例化合物能够作为CRL4CRBNE3泛素连接酶调节剂,通过调控CRBN-泛素连接酶 复合物的活性,选择性诱导底物蛋白进行泛素化并降解,可用于制备预防或治疗与CRL4CRBN E3 泛素连接酶相关的疾病的药物或诊断试剂。
综上所述,本发明提供了一类结构新颖的取代异吲哚啉类化合物,其中部分代表性化合物对测 试的血液瘤细胞表现出非常强的增殖抑制活性。此外,本发明提供的部分代表性化合物在其他肿瘤 细胞系中也有一定的活性。因此,本发明中结构新颖的化合物可以用于制备预防或治CRL4CRBN E3泛素连接酶相关疾病的药物或诊断试剂,可以实现进一步提高肿瘤的治疗效果治疗和扩展度胺 类药物的新适应症的临床上的需求;有望克服现有度胺类药物的应用局限。此项特征不仅可以有效 弥补现有度胺药物的不足,更能将其适应症拓展到新的领域,因此具有非常重要研究价值和应用前 景。
