Definitions

  • the invention belongs to the field of medicine, and relates to an azacyclic compound, its pharmaceutical composition and its application in preparing medicine.
  • the compound and the pharmaceutical composition thereof can be used as HIF-2 ⁇ regulators, and can be used to prepare medicines for treating cancer, inflammation, pulmonary hypertension, atherosclerosis or ischemic diseases and other related diseases.
  • HIFs are a class of nuclear transcription complexes that mediate intracellular hypoxia response, and are widely expressed in tissue cells to promote the adaptation process of organisms to hypoxia response.
  • HIFs mainly include HIF-1, HIF-2, and HIF-3, which are composed of oxygen-sensitive ⁇ -subunits (HIF-1 ⁇ , HIF-2 ⁇ , and HIF-3 ⁇ ) and constitutive ⁇ -subunits HIF-1 ⁇ (also known as It is a heterodimer composed of Aryl Hydrocarbon Receptor Nuclear Translocator (ARNT).
  • ALDT Aryl Hydrocarbon Receptor Nuclear Translocator
  • HIF-2 ⁇ is the master regulator of the pathological hypoxic response.
  • HIF-2 ⁇ When the oxygen concentration is normal, the half-life of HIF-2 ⁇ is short, and the two special prolines Pro405 and Pro531 in the ODDD domain of HIF-2 ⁇ are rapidly recognized by hydroxylase and hydroxylated. Hydroxylated HIF-2 ⁇ binds to VHL protein, and then is ubiquitinated by E3 ubiquitin ligase, and finally degraded rapidly by protease; while there are a large number of hypoxic regions or functionally defective VHL in various malignant tumors, at this time HIF -2 ⁇ accumulates in the cell and forms a heterodimer with continuously expressed ARNT, and finally binds to different molecules of hypoxia response elements (Hypoxia Esponse Elements, HRE), thereby regulating the transcription of various target genes.
  • hypoxia response elements Hypoxia Esponse Elements, HRE
  • Both the HIF-2 ⁇ subunit and the ARNT subunit belong to the Per-ARNT-Sim (PAS) subfamily of the basic helix-loop-helix (bHLH) family.
  • the two subunits have similar structures and mainly contain the N-terminal bHLH (DNA Bonding Domain , DBD, DNA binding region), and two adjacent PASA and PASB domains (Ligand Bonding Domain, LBD, ligand binding region); the C-terminus binds to transcription cofactors and regulates the transcription of downstream genes.
  • the study found that there is an approximately combined with regulators can affect the heterodimerization of HIF-2 ⁇ subunits and ARNT subunits, thereby blocking or activating DNA binding and transcription of target genes.
  • HIF-2 ⁇ downstream target genes such as vascular endothelial growth factor (VEGF), erythropoietin (EPO) and glycolytic enzymes, etc., these genes are related to tumors, inflammation, and blood diseases, so the development of HIF-2 ⁇ regulators has important clinical significance.

Description

氮杂并环衍生物、其药物组合物及其用途 技术领域
本发明属于医药领域,涉及一种氮杂并环化合物、其药物组合物及其在制备药物中的用途。具体地,所述化合物及其药物组合物可作为HIF-2α调节剂,可以用于制备治疗癌症、炎症、肺动脉高压、动脉粥样硬化或缺血性疾病等相关疾病的药物。
背景技术
HIFs是一类介导细胞内缺氧反应的核转录复合体,在组织细胞中广泛地表达,以促进生物体对缺氧反应的适应过程。HIFs主要包括HIF-1、HIF-2和HIF-3,它们都是由氧敏感的α亚基(HIF-1α、HIF-2α和HIF-3α)和组成型β亚基HIF-1β(也称为芳香烃受体核转运蛋白,Aryl Hydrocarbon Receptor Nuclear Translocator,ARNT)组成的异源二聚体。在三个α亚基中,HIF-2α是病理性缺氧回应的主要调控者。当氧气浓度正常时,HIF-2α的半衰期较短,HIF-2α的ODDD结构域中两个特殊的脯氨酸Pro405和Pro531迅速被羟基化酶识别并被羟基化。羟基化的HIF-2α与VHL蛋白结合,进而被E3泛素连接酶泛素化,最终被蛋白酶迅速降解;而在多种恶性肿瘤中存在大量的缺氧区域或者功能缺陷的VHL,此时HIF-2α在细胞内积蓄,并与持续表达的ARNT形成异源二聚体,最终与不同分子的缺氧反应元素(Hypoxia Esponse Elements,HRE)结合,从而调控多种靶基因的转录。
HIF-2α亚基和ARNT亚基均属于碱性螺旋-环-螺旋(bHLH)家族中Per-ARNT-Sim(PAS)亚科,两个亚基结构类似,主要包含N端的bHLH(DNA Bonding Domain,DBD,DNA结合区域),以及两个相邻的PASA和PASB结构域(Ligand Bonding Domain,LBD,配体结合区域);C端与转录辅助因子结合,调节下游基因的转录。研究发现HIF-2α亚基的PASB结构域的内部存在一个约的空腔,结合了调节剂后能够影响HIF-2α亚基和ARNT亚基形成异源二聚化,进而阻断或激活DNA的结合和靶基因的转录。HIF-2α下游靶基因如血管内皮细胞生长因子(VEGF)、红细胞生成素(EPO)以及糖酵解酶类等,这些基因与肿瘤、炎症,血液方面疾病有关,因此开发HIF-2α调节剂具有重要的临床意义。

与一种或多种辅剂结合以制备单剂型的活性成分的量将必需根据治疗的宿主和具体的给药路径而变化。式(I)、(II)或(II-1))化合物与载体材料混合以制备单一剂型的活性成分的量将根据待治疗的疾病、疾病的严重程度、给药时间、给药途径、所用化合物的排泄速率、治疗时间和患者年龄、性别、体重和情况而改变。优选的单位剂型是含有本文上述活性成分的日剂量或分剂量或其适宜分数的单位剂型。可用显然低于化合物最佳剂量的小剂量开始治疗。此后,以较小的增量来加大剂量直到在这种情况下达到最佳效果。一般而言,最理想地给予化合物的浓度水平是通常可在抗肿瘤方面提供有效结果而又不至于引起任何有害或有毒的副作用。
药物组合物适于通过任何合适的途径给药,例如通过口服(包括口腔或舌下)、直肠、鼻、局部(包括口腔、舌下或经皮)、阴道或胃肠外(包括皮下、皮内、肌内、关节内、滑膜内、胸骨内、鞘内、病灶内、静脉内或者真皮下注射或输注)途径。可按药剂学领域的任 何已知方法制备这类制剂,例如通过将活性成分与载体或赋形剂混合。优选口服给药或注射给药。
