Definitions

  • the invention belongs to the field of medicinal chemistry.
  • the present invention relates to novel compounds or stereoisomers, racemates, geometric isomers, tautomers, prodrugs, hydrates, solvates thereof or pharmaceutically acceptable salts thereof, and Pharmaceutical compositions containing them, which are BET (bromodomain and extra-terminal domain) inhibitors with novel structures, in particular inhibitors targeting BRD4 (Bromodomain-containing protein 4).
  • BET bromodomain and extra-terminal domain
  • Bromodomain-containing proteins are classified into eight families according to the similarity of structure and sequence, and the most studied one is the BET family.
  • the BET family consists of four members: BRD4, BRD3, BRD2 and BRDT, the first three are widely expressed in tissues, while BRDT is specifically expressed in the testis.
  • BRD4 and BRDT contain a C-terminal region that interacts with a forward transcription elongation factor (P-TEFb), which is not conserved.
  • P-TEFb forward transcription elongation factor
  • BRD4 is considered to be the most promising target for BET therapy and has attracted great interest from the pharmaceutical and academic communities, particularly in the treatment of cancer and inflammation.
  • NMC NUT midline cancer
  • NUT NUT fusion protein produced by the BRD4 chromosomal translocation to the nuclear protein (NUT) of the testis genome
  • the BET inhibitor JQ1 inhibits tumor squamous differentiation and growth by blocking the binding of BRD4 protein to chromatin-like lysine and causes it to resolve.
  • studies have shown that BET inhibitors can effectively down-regulate the transcription of MYC and target genes that are dependent on MYC in the whole genome.
  • BET inhibitors are promising for a wide range of uses in cancer treatment. Recent studies have found that in the MYC-driven B-cell lymphoma model, BET inhibitors show the best efficacy when the host has a good immune system.
  • the immunological checkpoint ligand CD274 (PD-L1) was identified as a target gene for the BET inhibitor by genome-wide analysis of the BET inhibitor-induced transcription reaction.
  • BET inhibitors In mouse and human tumor cell lines and patient samples, BET inhibitors not only down-regulated the expression of constant horizontally transcribed CD274, but also down-regulated the expression of CD274 induced by interferon-gamma (IFN- ⁇ ).
  • IFN- ⁇ interferon-gamma
  • the PD-1 antibody and the BET inhibitor JQ1 showed a synergistic effect.
  • RVX-208 Japaneseone
  • JQ1 parent benzodiazepine The developed molibresib (I-BET762, GSK525762), bicrabresib (OTX-015, MK8628), CPI-0610 and TEN-010/RG6146 are mainly used for the treatment of cancer.
  • Abbv-075 based on fragment design is currently in clinical stage I, and its clinical indication is solid tumor.

  • birabresib (OTX-015, MK8628) and BAY1238097 have actually been terminated for further clinical trials due to poor efficacy or toxicity.
  • BRD4 inhibitors As monotherapy or combination in the field of oncology and other diseases, it has remained critical to find that more efficient and safe BRD4 inhibitors meet patient needs.
  • the inventors of the present invention have rationally designed and synthesized a series of small molecule compounds of the novel structure represented by the following general formula (I), which have high bromodomain protein inhibitory activity, particularly BET inhibition, through repeated experimental studies.

Description

具有BET抑制活性的化合物及其制备方法和用途 技术领域
本发明属于药物化学领域。具体地,本发明涉及新的化合物或其立体异构体、外消旋物、几何异构体、互变异构体、前药、水合物、溶剂化物或其药学上可接受的盐,以及含有它们的药物组合物,它们是具有全新结构的BET(bromodomain and extra-terminal domain)抑制剂,尤其是靶向BRD4(Bromodomain-containing protein 4)的抑制剂。
背景技术
含溴结构域蛋白(bromodomain-containing protein,BCPs)根据结构和序列的相似性分为8个家族,其中被研究得最多的是BET家族。BET家族一共包括四个成员:BRD4,BRD3,BRD2和BRDT,前三者在组织中广泛表达,而BRDT在睾丸中特异性表达。这四种蛋白都有两个能够识别乙酰化赖氨酸残基的溴结构域,分别为BD1和BD2。BRD4和BRDT包含一个与正向转录延长因子(P-TEFb)作用的C-端区域,这段区域序列不保守。BET家族成员通过与乙酰化的组蛋白以及非组蛋白的相互作用来调节基因转录、复制、细胞周期进程和其他细胞活性,被认为是含溴结构域蛋白(BCPs)中成药性最高的表观遗传学靶蛋白。BRD4更被视为最有希望的BET治疗靶点,已经吸引了制药界和学术界的极大兴趣,特别是在癌症和炎症的治疗领域。例如,由于BRD4染色体易位到睾丸基因组的核蛋白(NUT)产生的BRD4-NUT融合蛋白所引起的c-MYC过表达而导致的NUT中线癌(NUT midline cancer,NMC),是一种对常规治疗无反应的侵袭性鳞状细胞恶性肿瘤。在人类NMC衍生的异种移植小鼠模型实验中,BET抑制剂JQ1通过阻断BRD4蛋白与染色质上乙酰赖氨酸的结合,抑制肿瘤鳞状分化和生长,并导致其消退。同时,研究显示BET抑制剂可以有效下调MYC的转录及在全基因组中依赖MYC的靶基因。鉴于MYC在癌症中的广泛致病作用,BET抑制剂很有希望在癌症治疗找到广泛的用途。最近研究发现在MYC驱动的B细胞淋巴瘤模型中,当宿主拥有完好的免疫系统时BET抑制剂表现出最好药效。通过全基因组分析BET抑制剂诱导的转录反应确定了免疫检查点配体CD274(PD-L1)为BET抑制剂的靶基因。在小鼠和人类的肿瘤细胞系及患者样品中,BET抑制剂不仅下调了恒定水平转录的CD274的表达,也下调由干扰素-γ(IFN-γ)诱导的CD274的表达。在MYC驱动的淋巴瘤小鼠模型中,PD-1抗体和BET抑制剂JQ1显示出协同效应。这些数据更为BET抑制剂与免疫检查点抑制剂PD-1/PD-L抗体在临床中的联合用药提供了强大的依据。
目前已有大批小分子BRD4抑制剂在临床研究阶段。比如加拿大Resverlogix公司的海普瑞(RVX-208,apabetalone)已经进入了临床III期,用于治疗心血管类疾病。基于JQ1母核苯二氮

开发出来的molibresib(I-BET762,GSK525762)、birabresib(OTX-015,MK8628)、CPI-0610和TEN-010/RG6146主要用于治疗癌症。来自于基于片段设计的Abbv-075,目前处于临床I期,其临床适应症是实体瘤。后续进入临床研究阶段的BRD4抑制剂还有BAY1238097、CC90010、FT1101、ZEN3694、PLX51107、INCB54329、GS5829、BMS98618和ODM207。 根据文献调研,birabresib(OTX-015,MK8628)和BAY1238097实际已经因药效不佳或毒性等原因被终止进一步的临床试验。鉴于BRD4抑制剂作为单药或者联合用药在肿瘤及其他疾病领域所具有广泛的前景,发现更高效和安全的BRD4抑制剂满足病人需求仍然至关重要。
发明内容
本发明的发明人通过反复的实验研究,合理设计与合成了一系列如下列通式(I)表示的新型结构的小分子化合物,其具有很高的溴结构域蛋白抑制活性,特别是BET抑制活性,更特别是靶向BRD4的抑制活性。这些化合物或其立体异构体、外消旋物、几何异构体、互变异构体、前药、水合物、溶剂化物、晶型或其药学上可接受的盐及药物组合物可用于治疗或/和预防由溴结构域蛋白介导的相关疾病。本发明还提供了制备通式(I)表示的化合物的方法、包含它们的药物组合物以及它们在制备药剂中的用途。

此外,如果本文所述的化合物是以酸加成盐的形式得到的,其游离碱形式可以通过碱化该酸加成盐的溶液获得。相反地,如果产物是游离碱形式,则其酸加成盐、特别是药学上可接受的酸加成盐可以按照由碱性化合物制备酸加成盐的常规操作通过将游离碱溶于合适的溶剂并且用酸处理该溶液来得到。本领域技术人员无需过多实验即可确定各种可用来制备无毒的药学上可接受的酸加成盐的合成方法。
本发明的化合物可以以溶剂化物的形式存在。术语“溶剂化物”意指包含化学计量的或非 化学计量的溶剂的溶剂加成形式。如果溶剂是水,则形成的溶剂化物是水合物,当溶剂是乙醇时,则形成的溶剂化物是乙醇合物。水合物是通过一个或多个分子的水与一分子所述物质形成的,其中水保留其H 2O的分子状态,这样的组合能形成一种或多种水合物,例如半水合物、一水合物和二水合物。
本文所用的术语“前药”指施用于个体后通过体内生理学作用如水解、代谢等被化学修饰成本发明的化合物的有活性或无活性的化合物。制备和使用前药中所涉及的适合性和技术是本领域技术人员所公知的。举例性的前药有例如游离羧酸的酯和硫醇的S-酰基衍生物和醇或酚的O-酰基衍生物。适合的前药通常是可在生理条件下通过溶剂解转化成母体羧酸的药学上可接受的酯衍生物,例如低级烷基酯、环烃基酯、低级链烯基酯、苄基酯、单-或二-取代的低级烷基酯,如ω-(氨基、单-或二-低级烷基氨基、羧基、低级烷氧基羰基)-低级烷基酯、α-(低级烷酰基氧基、低级烷氧基羰基或二-低级烷基氨基羰基)-低级烷基酯,如新戊酰基氧基甲基酯等,它们在本领域中是常规使用的。

本文所用的术语“预防”指给具有易患所述疾病的体质的个体施用一种或多种药物物质、特别是本文所述的式(I)化合物和/或其药学上可接受的盐,用以防止个体罹患该疾病。在一些实施方案中,所述疾病是与溴结构域蛋白相关的疾病。在进一步的实施方案中,所述疾病是与溴结构域蛋白高表达或高活性相关的疾病。在进一步的实施方案中,所述疾病是癌症如血液恶性肿瘤、中线癌和炎症疾病。
当涉及化学反应时,术语“处理”、“接触”和“反应”指在适当的条件下加入或混合两种或更多种试剂,以产生所示的和/或所需的产物。应当理解的是,产生所示的和/或所需的产物的反应可能不一定直接来自最初加入的两种试剂的组合,即,在混合物中可能存在生成的一个或多个中间体,这些中间体最终导致了所示的和/或所需的产物的形成。
本文所用的术语“有效量”指通常足以对个体产生有益效果的量。可以通过常规方法(例如建模、剂量递增研究或临床试验)结合常规影响因素(例如给药方式、化合物的药代动力学、疾病的严重程度和病程、个体的病史、个体的健康状况、个体对药物的响应程度等)来确定本发明的化合物的有效量。
术语“抑制”指生物活动或过程的基线活性的降低。术语“抑制溴结构域蛋白”或“抑制BRDs”指相对于不存在式(I)化合物或其药学上可接受的盐时的BRD活性而言,对存在本文所 述的式(I)化合物或其药学上可接受的盐的直接或间接响应导致的BRD活性的降低。活性的降低可以是由本文所述的式(I)化合物或其药学上可接受的盐与BRD直接相互作用引起的,或者是由本文所述的式(I)化合物和/或其药学上可接受的盐与一种或多种其它因子相互作用进而影响BRD活性引起的。
本文所用的术语“个体”指哺乳动物和非哺乳动物。哺乳动物指哺乳类的任何成员,其包括但不限于:人;非人灵长类动物,如黑猩猩及其它猿类和猴类物种;农场动物,如牛、马、绵羊、山羊和猪;家畜,如兔、狗和猫;实验室动物,包括啮齿类动物,如大鼠、小鼠和豚鼠;等等。非哺乳动物的实例包括但不限于鸟等。术语“个体”并不限定特定的年龄或性别。在一些实施方案中,个体是人。
