Definitions

  • the invention belongs to the field of drug development, and particularly relates to a guanamine 2,3-dioxygenase inhibitor and a preparation method and application thereof.
  • IDO Indoleamine 2,3-dioxygenase
  • Tryptophan is one of the eight essential amino acids. In vivo, tryptophan can be used to synthesize proteins. Tryptophan can also be used as a precursor substrate to synthesize serotonin and melatonin through the methoxypurine metabolic pathway (N- Acetyl-5-methoxytryptamine). Serotonin and melatonin are neurotransmitters and neuroendocrine hormones that are involved in the regulation of various neurological and physiological processes in the body. In addition, tryptophan can also produce metabolites such as kynurenine through the kynurenine metabolic pathway.
  • the first step in the kynurenine metabolic pathway is the tryptophan L-color ammonia catalyzed by indoleamine 2,3-dioxygenase or tryptophan 2,3-dioxygenase (TDO).
  • TDO tryptophan 2,3-dioxygenase
  • Canine uridine and 3-hydroxyanthranilic acid are involved in the regulation of lymphocyte activity leading to inhibition of the immune system.
  • indoleamine 2,3-dioxygenase In addition to placental tissue, indoleamine 2,3-dioxygenase is not expressed in most tissue cells under normal health conditions. In the region of inflammation, inflammatory cytokines such as interferon gamma can induce an increase in the expression of indoleamine 2,3-dioxygenase. The results of various experiments prove that the high expression of indoleamine 2,3-dioxygenase in tissue cells can lead to inhibition of the immune system of the tissue microenvironment, or immune suppression or immune checkpoint. . High expression of placental tissue indoleamine 2,3-dioxygenase prevents immune rejection of the fetus.
  • indoleamine 2,3-dioxygenase in the inflammatory region prevents excessive immune responses and prevents excessive damage to cellular tissues.
  • One of the mechanisms leading to inhibition of immunity is that high expression of indoleamine 2,3-dioxygenase causes local L-tryptophan depletion, which is sensed by surrounding lymphocytes through mechanisms such as GCN2, causing CD8+ cytotoxic T cells. Cell cycle arrest or apoptosis occurs.
  • Another mechanism that leads to inhibition of immunity is the high expression of indoleamine 2,3-dioxygenase, which causes an increase in kynurenine. After kynurenine formation, it leaves the cell and enters the extracellular matrix, and then enters the nearby lymph.
  • the cells regulate CD8+ T cells and regulatory Treg cells by binding to AHR transcription factors, and the activity of CD8+ cytotoxic T cells is inhibited, while the number of regulatory Treg cells is increased and activated, resulting in inhibition of immunity.
  • indoleamine 2,3-dioxygenase is abnormally highly expressed, including hematological tumors and solid tumors such as colorectal cancer, liver cancer, lung cancer, pancreatic cancer, and throat cancer.
  • the abnormally high expression of indoleamine 2,3-dioxygenase was positively correlated with poor tumor prognosis.
  • Tumor cell escape immune monitoring is a key step in the further development of cancer and cancer.
  • the abnormally high expression of indoleamine 2,3-dioxygenase in tumors may be the escape of tumor cells.

Description

吲哚胺2,3-双加氧酶抑制剂及其制备方法与应用 技术领域
本发明属于药物开发领域,具体涉及吲哚胺2,3-双加氧酶抑制剂及其制备方法与应用。
背景技术
吲哚胺2,3-双加氧酶(indoleamine 2,3-dioxygenase,简写IDO)是一种与色氨酸代谢有关的蛋白酶。色氨酸是八种必需氨基酸之一,在体内色氨酸可用来合成蛋白质,色氨酸还可作为前体底物通过甲氧基吲哚代谢途径合成5-羟色胺和褪黑激素(N-乙酰-5-甲氧基色胺)。5-羟色胺和褪黑激素是神经递质和神经内分泌激素,参与体内的多种神经与生理过程的调节。此外,色氨酸还可通过犬尿氨酸代谢途径产生犬尿氨酸等代谢产物。犬尿氨酸代谢途径的第一步是在吲哚胺2,3-双加氧酶或色氨酸2,3-双加氧酶(TDO)的催化作用下,色氨酸L-色氨酸降解为N-甲酰基-犬尿氨酸,N-甲酰基-犬尿氨酸在犬尿氨酸甲酰胺酶的催化作用下形成犬尿氨酸,犬尿氨酸还可被进一步代谢形成3-羟基邻氨基苯甲酸,喹啉酸,吡啶甲酸。喹啉酸具有神经毒性,而吡啶甲酸具有神经保护作用。犬尿氨酸和3-羟基邻氨基苯甲酸参与淋巴细胞活性调节从而引起免疫系統被抑制。
除胎盘组织外,正常健康状况下吲哚胺2,3-双加氧酶在多数组织细胞内基本不表达。在炎症发生区域,干扰素γ等炎性细胞因子可诱导吲哚胺2,3-双加氧酶表达量升高。多方面的实验结果证明,吲哚胺2,3-双加氧酶在组织细胞中的高表达可导致该组织微环境的免疫系統被抑制,或称免疫被抑制或免疫检查点(immune checkpoint)。胎盘组织吲哚胺2,3-双加氧酶的高表达可防止对胎儿的免疫排斥反应。炎症区域吲哚胺2,3-双加氧酶的高表达可防止过度的免疫反应,防止细胞组织受到过度的损伤。导致免疫被抑制的机制之一是吲哚胺2,3-双加氧酶高表达造成局部L-色氨酸耗竭,从而被周围的淋巴细胞通过GCN2等机制感受到,引起CD8+细胞毒性T细胞发生细胞周期停滞或凋亡。导致免疫被抑制的另一种机制是吲哚胺2,3-双加氧酶高表达造成犬尿氨酸升高,犬尿氨酸形成后可离开细胞进入细胞外基质,然后进入附近的淋巴细胞通过结合AHR转录因子对CD8+T细胞和调节性Treg细胞进行调节,CD8+细胞毒性T细胞的活性被抑制,而调节性Treg细胞的数量增多并且被激活,从而导致免疫被抑制。
在很多不同类型的肿瘤中吲哚胺2,3-双加氧酶发生异常高表达,包括血液肿瘤和直结肠癌、肝癌、肺癌、胰腺癌、咽喉癌等实体瘤。吲哚胺2,3-双加氧酶异常高表达与肿瘤不良预后呈正相关。肿瘤细胞逃脱免疫监控是癌变和癌症进一步发展的关键一步,肿瘤中吲哚胺2,3-双加氧酶的异常高表达可能是肿瘤细胞逃脱 免疫监控的一种主要机制,抑制吲哚胺2,3-双加氧酶的活性有可能激活被抑制的免疫系统,达到抑制肿瘤生长的效果,所以吲哚胺2,3-双加氧酶抑制剂作为一种免疫检查点抑制剂(immune checkpoint inhibitor)引起了医药界很大的兴趣。吲哚胺2,3-双加氧酶(IDO)有两种,IDO-1和IDO-2,参与上述免疫被抑制的主要是IDO-1,IDO-2在免疫被抑制中的作用还不是很清楚。色氨酸2,3-双加氧酶(TDO)也在很多类型的肿瘤中发生异常高表达,有的肿瘤还呈现IDO和TDO双阳性,所以有人认为也可通过抑制TDO免疫检查点起到肿瘤治疗的目的。因为正常肝脏细胞表达TDO,尚不清楚TDO抑制剂是否会影响肝脏功能和正常的色氨酸代谢,但TDO敲除得小鼠模型未见异常,表明TDO抑制剂可能不会影响肝脏功能和正常的色氨酸代谢。IDO和TDO导致免疫被抑制的机理基本相同,所以IDO/TDO双特异抑制剂也同样引起了医药界的兴趣,IDO/TDO双特异抑制剂将适用于IDO阳性、TDO阳性、IDO/TDO双阳性的病人。
色氨酸的犬尿氨酸代谢途径的很多代谢产物与精神分裂症,抑郁症,神经元退化有关,吲哚胺2,3-双加氧酶抑制剂可能也可用于这些疾病的治疗。犬尿氨酸在犬尿氨酸氨基转移酶的催化作用下可转化为犬尿喹啉酸,犬尿喹啉酸是一种NMDA拮抗剂,在精神分裂症病人的中枢神经中常见到较高的犬尿喹啉酸水平。喹啉酸具有神经毒性,可导致神经细胞凋亡和神经退化。吲哚胺2,3-双加氧酶不仅参与色氨酸代谢,还参与色氨等的代谢,5-羟色胺在吲哚胺2,3-双加氧酶的催化作用下可转化为5-羟吲哚乙酸,5-羟色胺下降可能是导致抑郁症的因素之一。
目前吲哚胺2,3-双加氧酶抑制剂的研发均处于早期,包括NewLink公司的Indoximod,NLG-919(IDO/TDO双特异性),Incyte公司的Epacadostat(INCB024360),以及BMS,Flexus,Iomet,Iteos,Curadev等公司的IDO或TDO抑制剂。专利WO2016041489A1公开了一系列磺酰亚氨基化合物,该类对吲哚胺2,3-双加氧酶(IDO)具有很好的抑制活性,但该专利公开的最好化合物6相对于INCB-24360的暴露量(AUC)提升幅度有限,且T1/2很短,不利于临床开发;化合物13(化合物6前药)虽然延长了T1/2,但其暴露量(AUC)还不如INCB-24360,因此,进一步开发具有适合临床给药的T1/2,同时具有较高暴露量(AUC)的化合物吸引了世界许多科学家为此不断努力。
发明内容
发明人在一系列研究后发现N'-羟基-N-苯基甲脒衍生物,对吲哚胺2,3-双加氧酶(IDO)具有很高的抑制活性,而对色氨酸2,3-双加氧酶(TDO)没有抑制活性,并且在PK动物模型中具有非常好的暴露量(AUC),同时具有非常适合临床应用的T1/2。该类化合物能够有效抑制IDO的活性,也可用于抑制患者的免疫抑制。可广泛应用于治疗或预防癌症或肿瘤、病毒感染、抑郁症、神经变性 病症、创伤、年龄相关的白内障、器官移植排斥或自身免疫疾病,有望开发成新一代免疫抑制剂。
