Definitions

  • the present disclosure belongs to the field of medical technology, and specifically relates to a protein targeted degradation chimera (PROTAC) compound containing a cereblon E3 ubiquitin ligase ligand, or a pharmaceutically acceptable salt thereof, which has biological activities such as anti-proliferation of tumor cells and can be used for the treatment of related diseases.
  • PROTAC protein targeted degradation chimera
  • CRBN Cereblon
  • CRBN is a protein encoded by the CRBN gene in the human body.
  • CRBN is widely expressed in the testis, spleen, prostate, liver, pancreas, placenta, kidney, lung, skeletal muscle, ovary, small intestine, peripheral blood leukocytes, colon, brain and retina, and its expression in brain tissue (including retina) and testis is significantly higher than that in other tissues.
  • CRBN As an important target for anti-tumor and immunomodulator drugs, CRBN has been proven to have clear therapeutic effects in multiple myeloma, chronic lymphocytic leukemia and other blood malignancies, as well as autoimmune diseases such as systemic lupus erythematosus.
  • existing doxorubicin drugs have many side effects, especially peripheral neuropathy. At present, it is necessary to develop new CRBN modulator drugs to improve clinical treatment effects, reduce clinical side effects, and facilitate long-term use by patients.
  • the ubiquitin-proteasome pathway is a key pathway for regulating key regulatory proteins and degrading misfolded or abnormal proteins.
  • Ubiquitin molecules are covalently linked to terminal lysine residues by E3 ubiquitin ligases to tag proteins for proteasomal degradation, where the protein is digested into small peptides and ultimately into its constituent amino acids, which serve as building blocks for new proteins.
  • the UPP is important for multiple cellular processes and, if defective or unbalanced, it contributes to the pathogenesis of multiple diseases. Defective proteasomal degradation has been shown to be associated with a variety of clinical conditions, including Alzheimer's disease, Parkinson's disease, Huntington's disease, muscular dystrophy, cardiovascular disease, and cancer.
  • PROTAC Protein-mediated chimeras
  • UPS ubiquitin-proteasome system
  • PROTAC molecules are bifunctional molecules that can both bind to target proteins and recruit E3 ubiquitin ligases to ubiquitinate the target protein, which is then degraded by the proteasome. Therefore, CRBN ligands can also be used to prepare bifunctional PROTAC compounds for the treatment of related diseases.

Description

一类稠环化合物及其用途

技术领域
本公开属于医药技术领域,具体的涉及一种含有多并环类小脑蛋白(cereblon)E3泛素连接酶配体的蛋白靶向降解的嵌合体(PROTAC)化合物,或其药学上可接受的盐,其具有对肿瘤细胞的抗增殖等生物活性,可用于相关疾病的治疗。
背景技术
CRBN(Cereblon)是一种在人体内由CRBN基因编码的蛋白质。CRBN广泛地表达在睾丸、脾、前列腺、肝脏、胰腺、胎盘、肾脏、肺、骨骼肌、卵巢、小肠、外周血白细胞、结肠、脑部以及视网膜中,而在脑组织(包括视网膜)以及睾丸中的表达显著高于其他组织。
CRBN作为抗肿瘤和免疫调节剂药物的重要靶点,已被证实在多发性骨髓瘤、慢性淋巴细胞白血病等多种血液性恶性肿瘤,系统性红斑狼疮等自身免疫性疾病具有明确的疗效。但是现有的度胺类药物都有较多副作用,尤其是周围神经病变。当前需要开发新的CRBN调节剂药物,来提高临床治疗效果,降低临床副作用,利于患者长期使用。
泛素-蛋白酶体途径(UPP)是调节关键调节蛋白和降解错折叠或异常蛋白的关键途径。泛素分子通过E3泛素连接酶与末端赖氨酸残基的共价连接对蛋白质进行标记以进行蛋白酶体降解,其中该蛋白质被消化成小肽并最终消化成其组成氨基酸,所述氨基酸用作新蛋白质的构建模块。UPP对于多个细胞过程是重要的,如果有缺陷或失衡,它会导致多种疾病的发病机理。现已证实有缺陷的蛋白酶体降解与多种临床病症有关,所述病症包括阿尔茨海默病、帕金森病、亨廷顿病、肌营养不良、心血管疾病和癌症等。靶向蛋白降解嵌合体PROTAC(Proteolysis targeting chimeras)是一种基于细胞自身的泛素-蛋白酶体系统(UPS)发展而来的新型靶向降解目标蛋白的技术。PROTAC分子是一种双功能的分子,既能与目标蛋白结合,又能招募E3泛素连接酶,从而将目标蛋白泛素化,进而通过蛋白酶体将目标蛋白降解。因此,还可以利用CRBN配体制备双功能性PROTAC化合物,用于治疗相关疾病。

本文中表示连接位点。对于本文中未与固定的环或原子相连时,表示其可与“[]”内的结构中含可被取代的氢原子(包括直接与环原子相连的氢原子、环原子的非氢取代基上的氢原子以及取代基上进一步的取代基中的氢原子)的任意位点失去该氢原子以后的基团相连,例如的连接位置包括但不限于Y1、Y2、Y3、Y4、X以及它们的取代基等。
本文中消旋体或者对映体纯的化合物的图示法来自Maehr,J.Chem.Ed.1985,62:114-120。除非另有说明,用楔形键和虚楔键表示一个立体中心的绝对构型,用黑实键和虚键表示一个立体中心的相对构型(如脂环化合物的顺反构型)。
术语“互变异构体”是指因分子中某一原子在两个位置迅速移动而产生的官能团异构体。本公开化合物可表现出互变异构现象。互变异构的化合物可以存在两种或多种可相互转化的种类。互变异构体一般以平衡形式存在,尝试分离单一互变异构体时通常产生一种混合物,其理化性质与化合物的混合物是一致的。平衡的位置取决于分子内的化学特性。例如,在很多脂族醛和酮如乙醛中,酮型占优势;而在酚中,烯醇型占优势。本公开包含化合物的所有互变异构形式。
术语“立体异构体”是指由分子中原子在空间上排列方式不同所产生的异构体,包括顺反异构体、对映异构体和非对映异构体。
本公开的化合物可以具有不对称原子如碳原子、硫原子、氮原子、磷原子或不对称双键,因此本公开的化合物可以存在特定的几何或立体异构体形式。特定的几何或立体异构体形式可以是顺式和反式异构体、E型和Z型几何异构体、(-)-和(+)-对映体、(R)-和(S)-对映体、非对映异构体、(D)-异构体、(L)-异构体,以及其外消旋混合物或其它混合物,例如对映异构体或非对映体富集的混合物,以上所有这些异构体以及它们的混合物都属于本公开化合物的定义范围之内。烷基等取代基中可存在另外的不对称碳原子、不对称硫原子、不对称氮原子或不对称磷原子,所有取代基中涉及到的这些异构体以及它们的混合物,也均包括在本公开化合物的定义范围之内。本公开的含有不对称原子的化合物可以以光学活性纯的形式或外消旋形式被分离出来,光学活性纯的形式可以从外消旋混合物拆分,或通过使用手性原料或手性试剂合成。
术语“被取代”是指特定原子上的任意一个或多个氢原子被取代基取代,只要特定原子的 价态是正常的并且取代后的化合物是稳定的。当取代基为氧代(即=O)时,意味着两个氢原子被取代,氧代不会发生在芳香基上。

当任何变量(例如Ra、Rb)在化合物的组成或结构中出现一次以上时,其在每一种情况下的定义都是独立的。例如,如果一个基团被2个Rb所取代,则每个Rb都有独立的选项。
当其中一个变量选自化学键或不存在时,表示其连接的两个基团直接相连,比如A-L-Z中L代表键时表示该结构实际上是A-Z。
当本文中涉及到的连接基团若没有指明其连接方向,则其连接方向是任意的。例如当结构单元中的L1选自“C1-C3亚烷基-O”时,此时L1既可以按照与从左到右的方向连接环Q和R1构成“环Q-C1-C3亚烷基-O-R1”,也可以按照从右到左的方向连接环Q和R1构成“环Q-O-C1-C3亚烷基-R1”。
当一个取代基的键交叉连接到一个环上的两个原子时,这种取代基可以与这个环上的任意原子相键合。例如,结构单元表示R5可在苯环上的任意一个位置发生取代。
