Definitions

  • the present invention belongs to the pharmaceutical field and relates to a pharmaceutically acceptable salt and a crystal form of a tetralin derivative.
  • Protein proteolysis-targeting chimera is a hybrid bifunctional small molecule compound. Its structure contains two different ligands: one is the E3 ubiquitin ligase ligand, and the other is the target protein binding ligand, and the two ligands are connected by a connecting arm.
  • PROTAC forms a target protein-PROTAC-E3 ternary complex by bringing the target protein and the E3 ubiquitin ligase in the cell closer. Then the E3 ubiquitin ligase marks the target protein with a ubiquitinated protein tag, initiates a powerful ubiquitination hydrolysis process in the cell, and uses the ubiquitin-proteasome pathway to specifically degrade the target protein.
  • PROTAC Compared with traditional small molecule inhibitors, PROTAC has unique advantages: 1. PROTAC does not need to bind to the target protein for a long time and with high intensity, and the process of degrading the target protein is similar to a catalytic reaction. It can cyclically bind and degrade the target protein, thereby reducing the systemic exposure of the drug and reducing the occurrence of toxic side effects. 2. After the target protein is degraded, it needs to be resynthesized to restore its function. Therefore, degrading the target protein shows a more efficient and lasting anti-tumor effect than inhibiting its activity, and there will be no drug resistance caused by target protein mutation. 3. PROTAC also has therapeutic potential for targets that are currently considered undruggable, such as transcription factors, scaffold proteins, and regulatory proteins.
  • cerebellar protein (CRBN) type E3 ligase ligands is related to the study of the mechanism of action of thalidomide.
  • CRBN cerebellar protein
  • thalidomide and its derivatives can be used as anti-inflammatory drugs, anti-angiogenic drugs and anti-cancer drugs.
  • lenalidomide and pomalidomide have greatly improved in safety, and the teratogenic effect has been significantly reduced.
  • lenalidomide works by degrading two special B cell transcription factors - Ikaros family zinc finger structure proteins 1 and 3 (IKZF1 and IKZF3). This study reveals the mechanism of action of thalidomide and its derivatives: by binding to the CRBN type E3 ubiquitin ligase protein complex, and then degrading the target protein.
  • PCT/CN2022/083597 discloses a new type of tetralin derivatives, among which compound I, chemically named (S)-3-(5-(4-((1-(4-((1R,2R)-6-hydroxy-2-isobutyl-1,2,3,4-tetralin- 1-yl)phenyl)piperidin-4-yl)methyl)piperazin-1-yl)-1-oxoisoindolin-2-yl)piperidine-2,6-dione, showing its use as an estrogen receptor degrader in the treatment of estrogen receptor-mediated or dependent diseases.

技术领域
本公开属于制药领域,涉及一种四氢萘类衍生物的可药用盐及晶型。
背景技术
蛋白水解靶向嵌合物(protein proteolysis-targeting chimera,PROTAC)是一种杂合双功能小分子化合物。其结构中含有两种不同配体:一个是E3泛素连接酶配体,另一个是与靶蛋白结合配体,两个配体之间由连接臂相连。PROTAC通过将目标靶蛋白和细胞内的E3泛素连接酶拉近,形成靶蛋白-PROTAC-E3三元复合物,接着E3泛素连接酶给靶蛋白标记泛素化蛋白标签,启动细胞内强大的泛素化水解过程,利用泛素-蛋白酶体途径特异性地降解靶蛋白。与传统的小分子抑制剂相比,PROTAC展现出了独特的优势:1、PROTAC不需要与目标靶蛋白长时间和高强度的结合,并且降解靶蛋白过程类似于催化反应,可循环结合、降解靶蛋白,从而降低药物的系统暴露量,减少毒副作用的发生。2、靶蛋白被降解后需要重新合成才能恢复功能,因此降解靶蛋白比抑制其活性显示出更加高效、持久的抗肿瘤作用,且不会发生因靶蛋白突变而产生的耐药性。3、对于目前认为不可成药的靶点,例如转录因子、支架蛋白和调控蛋白等,PROTAC也具有治疗潜力。
小脑蛋白(CRBN)类型的E3连接酶配体的发现与沙利度胺作用机制的研究相关。2010年,在研究沙利度胺毒性时发现,体内沙利度胺与CRBN的结合可能是沙利度胺致畸性的原因(Science,2010,327,1345)。后续研究发现沙利度胺及其衍生物可用作抗炎药物、抗血管生药物和抗癌药物。其中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。进一步研究表明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)。该研究揭示了沙利度胺及其衍生物的作用机制:通过与CRBN类型的E3泛素连接酶蛋白复合物结合,进而降解目标蛋白。
在此基础上,CRBN配体被广泛应用于蛋白降解剂的制备中,一系列以CRBN配体为基础的PROTAC分子被开发出来。PCT/CN2022/083597公开了一类新型的四氢萘类衍生物,其中化合物I,化学名为(S)-3-(5-(4-((1-(4-((1R,2R)-6-羟基-2-异丁基-1,2,3,4-四氢萘- 1-基)苯基)哌啶-4-基)甲基)哌嗪-1-基)-1-氧代异吲哚啉-2-基)哌啶-2,6-二酮,展示了其作为雌激素受体降解剂在治疗雌激素受体介导或依赖性的疾病中的应用。
作为药用活性成分的晶型结构往往影响到该药物的化学和物理稳定性,结晶条件及储存条件的不同有可能导致化合物的晶体结构的变化,有时还会伴随着产生其他形态的晶型。一般来说,无定形的药物产品没有规则的晶体结构,往往具有其它缺陷,比如产物稳定性较差,过滤较难,易结块,流动性差等。因此,研究(S)-3-(5-(4-((1-(4-((1R,2R)-6-羟基-2-异丁基-1,2,3,4-四氢萘-1-基)苯基)哌啶-4-基)甲基)哌嗪-1-基)-1-氧代异吲哚啉-2-基)哌啶-2,6-二酮的可药用盐、晶型,对开发适合工业生产且生物活性良好的药物具有重要意义。
