Definitions

  • the present disclosure belongs to the field of medicine, and relates to a novel fused imide-like cerebellar protein (cereblon) E3 ubiquitin ligase protein-binding ligand compound and protein degradation targeting chimera (PROTACs) compound containing it, and its preparation Method, and its application in medicine.
  • the present disclosure relates to a novel condensed imide-like cerebellar protein (cereblon) E3 ubiquitin ligase protein-binding ligand compound represented by general formula (IM) and a protein degradation targeting chimera containing the same (PROTACs) compounds, their preparation methods, and their applications in medicine.
  • IM general formula
  • PROTACs protein degradation targeting chimera
  • PROTACs PROteolysis TArgeting Chimeras
  • the PROTACs molecule is a bifunctional molecule. One end contains a ligand that binds to E3 ubiquitin ligase, and the other end contains a ligand that binds to the target protein. The two parts are connected by a connecting unit. The linking unit is pulled closer, so that the E3 ligase and the target protein are very close, which in turn causes the polyubiquitination of the target protein and the degradation of the proteasome.
  • PROTACs adopt a completely different mechanism of action and mechanism from small molecule inhibitors.
  • the ligand of E3 ubiquitin ligase recruits E3 ubiquitin ligase to the vicinity of the target protein, and then the target protein is labeled with ubiquitination by narrowing the distance with the target protein.
  • the labeled target protein will be degraded by the proteasome system in the body to inhibit the corresponding protein pathway (Cell Biochem Funct. 2019, 37, 21-30).
  • PROTACs Compared with traditional small molecule drugs, due to changes in the binding mechanism, PROTACs only need to instantaneously bind to the target protein to complete the process of ubiquitin transfer to achieve irreversible degradation of the target protein.
  • PROTACs have the following advantages: 1) stronger degradation and longer-lasting efficacy; 2) higher selectivity for the target protein; 3) can overcome the traditional small molecule inhibitors caused by the mutation of the target protein Drug resistance (Cell Chem. Biol. 2018, 25, 67-77).
  • the discovery process of CRBN type E3 ligase ligand is related to the study of thalidomide's mechanism of action.
  • cereblon is a binding protein of thalidomide (Science 2010, 327, 1345).
  • Cerebellar protein is part of the E3 ubiquitin ligase protein complex, which acts as a substrate receptor to select ubiquitinated proteins.
  • the study shows that thalidomide-cerebellar protein binding in vivo may be the cause of thalidomide teratogenicity.
  • the compound and related structures can be used as anti-inflammatory agents, anti-angiogenic agents and anti-cancer agents.
  • Lenalidomide and pomalidomide obtained by further modification of the structure of thalidomide have greatly improved their safety and significantly reduced their teratogenic effects.
  • Lenalidomide has been approved by the FDA in 2006 for marketing.
  • Two technological papers published in Science in 2014 pointed out that lenalidomide works by degrading two special B cell transcription factors, Ikaros family zinc finger structural proteins 1 and 3 (IKZF1 and IKZF3), which further reveals The structure of thalidomide may be combined with the E3 ubiquitin ligase protein complex of the cerebellar protein to further play a role in degrading the target protein (Science, 2014, 343, 301; Science, 2014, 343, 305).
  • CRBN ligands are widely used in protein degradation, and a series of PROTACs molecules based on CRBN ligands have been developed. Due to the influence of CRBN ligand itself on the target point, it may additionally degrade zinc finger domain protein. Therefore, the design and synthesis of new and highly selective CRBN ligands is also particularly important in the synthesis of PROTACs molecules.
  • the present invention develops a new type of fused imide derivatives, which can be used as effective cerebellar protein (CRBN) ligands, and can further synthesize corresponding PROTACs molecules. These molecules demonstrate their application as estrogen receptor degrading agents to treat estrogen receptor-mediated or dependent diseases.

稠合酰亚胺类衍生物、其制备方法及其在医药上的应用

技术领域
本公开属于医药领域,是关于一种新型稠合酰亚胺类小脑蛋白(cereblon)E3泛素连接酶蛋白质结合的配体化合物和包含其的蛋白降解靶向嵌合体(PROTACs)化合物,其制备方法,及其在医药上的应用。具体而言,本公开涉及一种通式(IM)所示的新型稠合酰亚胺类小脑蛋白(cereblon)E3泛素连接酶蛋白质结合的配体化合物和包含其的蛋白降解靶向嵌合体(PROTACs)化合物、其制备方法,及其在医药上的应用。本发明在医药上的应用展示了(但是不限制)其作为雌激素受体降解剂治疗雌激素受体介导的或依赖性的疾病或病症的用途。
背景技术
蛋白降解靶向嵌合体PROTACs(PROteolysis TArgeting Chimeras)技术的概念是在2001年提出的(Proc.Natl.Acad.Sci.USA,2001,98,8584)。早期的PROTACs通过肽段招募E3连接酶,分子透膜性较差,活性受限;2008年出现了基于MDM2E3连接酶的小分子PROTACs,但这些分子的活性并不好;直到2010到2012年,出现了目前常用的基于小脑蛋白(CRBN,cereblon)和VHL(von Hippel-Lindau)的E3连接酶的配体,使得小分子配体与E3连接酶的结合水平达到了微摩尔级别,为后面PROTACs的发展奠定了基础。
PROTACs分子是一种双功能的分子,其一端含有结合E3泛素连接酶的配体,另一端含有结合靶蛋白的配体,两部分之间通过连接单元连接起来。通过连接单元拉近,从而使E3连接酶和靶蛋白非常接近,进而引起靶蛋白的聚泛素化和蛋白酶体的降解。PROTACs采用与小分子抑制剂完全不同的作用机制和机理。首先,E3泛素连接酶的配体招募E3泛素连接酶到目标蛋白附近,通过与目标蛋白拉近距离,进而对目标蛋白进行泛素化标记。经标记后的目标蛋白会被体内的蛋白酶体系统进行降解,进而达到抑制相应蛋白通路的作用(Cell Biochem Funct.2019,37,21-30)。与传统的小分子药物相比,由于结合机理的改变,PROTACs仅需要与目标蛋白的瞬时结合来完成泛素转移的过程就可以实现目标蛋白不可逆的降解。因此,PROTACs具有以下的优点:1)更强的降解作用和更持久的药效;2)对目标蛋白更高的选择性;3)可以克服传统小分子抑制剂由于靶蛋白变异而带来的耐药作用(Cell Chem.Biol.2018,25,67-77)。
关于CRBN类型的E3连接酶配体的发现过程是和研究沙利度胺的作用机制相 关的。2010年,科学家在研究沙利度胺毒性的过程中发现小脑蛋白(cereblon)是一种沙利度胺的结合蛋白(Science 2010,327,1345)。小脑蛋白是E3泛素连接酶蛋白复合物的一部分,它作为底物受体选择作用于泛素化的蛋白质。该研究表明,体内沙利度胺-小脑蛋白结合可能是沙利度胺致畸性的原因。后续研究发现该化合物和相关结构可用作抗炎剂、抗血管生成剂和抗癌剂。对沙利度胺结构的进一步改造得到的来那度胺和泊马度胺在安全性上有了很大的提高,致畸作用明显降低,来那度胺已经在2006年经FDA批准上市。2014年在Science上发表了两篇开创性论文指出来那度胺发挥作用是通过降解两种特殊的B细胞转录因子,Ikaros家族锌指结构蛋白1和3(IKZF1和IKZF3),这进一步揭示了沙利度胺结构可能通过与小脑蛋白的E3泛素连接酶蛋白复合物相结合,进而在降解目标蛋白中进一步发挥作用(Science,2014,343,301;Science,2014,343,305)。
在此基础上,CRBN配体被广泛应用于蛋白降解中,一系列以CRBN配体为基础的PROTACs分子被开发了出来。由于CRBN配体本身对作用靶点的影响,可能会额外降解锌指结构域蛋白,因此新的、高选择性的CRBN配体的设计合成在PROTACs分子的合成中也格外重要。
本发明发展了一类新型的稠合酰亚胺类衍生物,它们可以作为有效的小脑蛋白(CRBN)配体,进一步可以合成相应的PROTACs分子。这些分子展示了其作为雌激素受体降解剂治疗雌激素受体介导的或依赖性的疾病应用。

本发明还包括各种氘化形式的通式化合物。与碳原子连接的各个可用的氢原子可独立地被氘原子替换。本领域技术人员能够参考相关文献合成氘化形式的通式化合物。在制备氘代形式的通式化合物时可使用市售的氘代起始物质,或它们可使用常规技术采用氘代试剂合成,氘代试剂包括但不限于氘代硼烷、三氘代硼烷四氢呋喃溶液、氘代氢化锂铝、氘代碘乙烷和氘代碘甲烷等。
“任选”或“任选地”意味着随后所描述的事件或环境可以但不必发生,该说明包括该事件或环境发生或不发生地场合。例如,“任选被烷基取代的杂环基团”意味着烷基可以但不必须存在,该说明包括杂环基团被烷基取代的情形和杂环基团不被烷基取代的情形。
“取代的”指基团中的一个或多个氢原子,优选为最多5个,更优选为1~3个氢原子彼此独立地被相应数目的取代基取代。不言而喻,取代基仅处在它们的可能的化学位置,本领域技术人员能够在不付出过多努力的情况下(通过实验或理论)确定可能或不可能的取代。例如,具有游离氢的氨基或羟基与具有不饱和(如烯属)键的碳原子结合时可能是不稳定的。
“药物组合物”表示含有一种或多种本文所述化合物或其生理学上/可药用的盐或前体药物与其他化学组分的混合物,以及其他组分例如生理学/可药用的载体和赋形剂。药物组合物的目的是促进对生物体的给药,利于活性成分的吸收进而发挥生物活性。
“可药用盐”是指本发明化合物的盐,这类盐用于哺乳动物体内时具有安全性和有效性,且具有应有的生物活性。
针对药物或药理学活性剂而言,术语“治疗有效量”是指无毒的但能达到预期效果的药物或药剂的足够用量。有效量的确定因人而异,取决于受体的年龄和一般情况,也取决于具体的活性物质,个案中合适的有效量可以由本领域技术人员根据常规试验确定。

以下结合测试例进一步描述解释本公开,但这些实施例并非意味着限制本公开的范围。
测试例1本公开化合物与E3泛素连接酶小脑蛋白(CRBN)的结合活性
本公开化合物与E3泛素连接酶CRBN的结合活性由本公开化合物抑制HEK293细胞(ATCC,CRL-1573)中表达的NanoLuc-CRBN和NanoBRET TM细胞内CRBN示踪物结合的活性反映。使用NanoBRET TM TE In-Cell CRBN试剂盒(Promega,Cat#CS1810C135)中的NanoLuc-CRBN质粒转染HEK293细胞。在6孔板每孔中接种1×10 6的HEK293细胞,用含有10%胎牛血清的DMEM/高葡萄糖(GE Healthcare,Cat#SH30243.01)完全培养基培养。使用Lipofectamine TM 3000转染试剂(Invitrogen, Cat#L3000015),每孔细胞转染0.5μg的NanoLuc-CRBN质粒,置于37℃培养箱中孵育过夜。
转染后的HEK293细胞经胰酶消化后用无酚红Opti-MEM培养基(Gibco,Cat#11058021)洗一遍。然后用无酚红Opti-MEM培养基将细胞密度调整为2.2×10 5个/mL,在白色平底384孔板(Corning,Cat#3574)中每孔加入45μL即10000个细胞。用Bravo自动分液系统将待测化合物在DMSO中配制成首浓度为2mM,3倍梯度稀释的10个浓度点。用无酚红Opti-MEM培养基将化合物进一步进行10倍稀释,在384孔板中每孔加入5μL稀释后的化合物与细胞混合,置于37℃培养箱孵育1小时。用DMSO将400μM的细胞内CRBN示踪物稀释至50μM,然后再用试剂盒中的NanoBRET示踪物稀释缓冲液进一步稀释至10μM,在384孔板中每孔加入2.5μL稀释后的示踪物,没有示踪物的对照孔加入缓冲液稀释的相应体积的DMSO,用排枪反复吹吸混匀后置于37℃培养箱孵育2小时。用无酚红Opti-MEM将试剂盒中的底物和抑制剂分别稀释166.7和500倍,配制底物溶液。384孔板中每孔加入25μL底物溶液,用排枪反复吹吸混匀。用PHERAstar FS酶标仪的Luminescence dual emission模块读取450nm(供体发射信号)和610nm(受体发射信号)荧光值,按照公式[(受体发射信号 样品/供体发射信号 样品)–(受体发射信号 无示踪物对照/供体发射信号 无示踪物对照)]×1000计算BRET比率值。将没有示踪物的阴性对照孔的BRET比率值设为100%抑制,将无化合物孔的BRET比率值设为0%抑制。计算化合物各浓度对CRBN蛋白与示踪物结合的抑制率,使用GraphPad Prism软件绘制化合物的量效曲线并计算IC 50值。
