  • the present disclosure belongs to the field of medicinal chemistry. Specifically, the present disclosure relates to pyrimidinedione compounds, and more particularly, the present disclosure relates to a pyrimidinedione compound, a preparation method thereof, and use thereof in the preparation of medicines.
  • CD73 also known as extracellular 5'-nucleotide hydrolase, is an exonuclease belonging to the metallophosphatase superfamily and is a peripheral glycoprotein whose major form is anchored by glycosylphosphatidylinositol (GPI) It is fixed on the plasma membrane with a molecular weight of 70KD and is encoded by the NT5E gene.
  • GPI glycosylphosphatidylinositol
  • CD73 is widely expressed on the cell surface of different tissues, including brain, lung, heart, spleen, lymph node, kidney, colon, vascular endothelium, and bone marrow; it is also expressed on various immune cells, including macrophages, neutrophils, myeloid suppression cells (MDSCs), dendritic cells (DCs), natural killer cells (NKs), and regulatory T cells (Tregs) (Soleimani A et al., Biochimie, 2020, 176:21-30.); a variety of tumor cells also have Highly expressed CD73, such as: melanoma, breast cancer, pancreatic cancer, ovarian cancer, colon cancer and prostate cancer, etc. (Gao Z et al., Biomed Res Int, 2014, 2014:460654.). CD73 is also present in a soluble form (sCD73) in biological fluids, including serum, and preserves holoenzyme activity.
  • sCD73 soluble form
  • CD73 mainly exerts physiological and pathological effects by hydrolyzing AMP (adenosine monophosphate) to produce extracellular adenosine (ADO).
  • ADO is associated with four G protein-coupled receptors (GPCRs): A1 adenosine A2A adenosine receptor (A2AR), A2B adenosine receptor (A2BR) and A3 adenosine receptor (A3AR) play a role, of which A2AR plays a major role (Linden J et al., Annu.Rev.Immunol., 2019, 37:325-347.).
  • GPCRs G protein-coupled receptors
  • Adenosine receptors are not only expressed in tumor cells, but also expressed on the cell surface of immune cells and vascular endothelial cells infiltrated in the tumor microenvironment. After binding to the receptors, ADO produces a variety of immunosuppressive and tumor-promoting effects. .
  • CD73 is closely related to tumor growth, angiogenesis and metastasis. Under normal physiological conditions, the extracellular ADO level is between 20 and 300 nM, but in the tumor microenvironment, the increase is maintained to the micromolar level (30-100 ⁇ M), and the high extracellular ADO concentration is mainly generated by CD73 hydrolysis of AMP affected. Studies have shown that soluble CD73 (sCD73) levels are increased in the plasma of cancer patients compared to healthy individuals (Klemens MR et al., Biochem. Biophys. Res. Commun., 1990, 172:1371-7..).
  • CD73 is upregulated in pancreatic ductal carcinoma (PDAC) compared to normal pancreatic tissue and is associated with tumor size, lymph node metastasis, metastasis and poor prognosis (Harvey Jerry B et al, Front Immunol, 2020, 11:508.).
  • PDAC pancreatic ductal carcinoma
  • ORIC-533 significantly reduced the ADO concentration in the tumor microenvironment while reducing tumor volume.
  • CD73 inhibitors can block tumor growth by releasing immunosuppression, and can also be used in combination with other targeted therapies and/or immunotherapy and radiotherapy to increase the anti-tumor effect.
  • CD73 can block tumor growth by releasing immunosuppression, and can also be used in combination with other targeted therapies and/or immunotherapy and radiotherapy to increase the anti-tumor effect.
  • anti-CD73 with anti-PD-L1 (programmed death receptor-ligand 1) and/or anti-CTLA-4 (cytotoxic T lymphocyte-associated protein 4) antibodies was more effective than alone Treatment with anti-PD-L1 and/or anti-CTLA-4 antibodies is more effective (Allard B et al, Clin.
  • CD73 in melanoma patients receiving PD-1 immunotherapy levels were found to be up-regulated, whereas a distinct CD73-high macrophage population persisted in glioblastoma patients after anti-PD-1 treatment, and CD73 deficiency enhanced anti-PD-1 and anti-CTLA-4 in mouse glioblastoma Efficacy in a cell tumor model (Goswami S et al., Nat.Med., 2020, 26:39-46.); radiotherapy leads to the destruction of some tumor cells, so that a large amount of intracellular ATP is released to the outside, on the surface of tumor cells or Under the action of free CD73, it is converted into adenosine, which produces an immunosuppressive effect, which is considered to be one of the reasons for the poor prognosis of some patients after radiotherapy, so the combination of CD73 inhibitor and radiotherapy may have a synergistic effect (Wennerberg E et al., Cancer Immunol Res, 2020

Description

嘧啶二酮类化合物及其用途
优先权信息
本申请请求2020年09月30日向中国国家知识产权局提交的、专利申请号为202011060399.4的专利申请的优先权和权益,并且通过参照将其全文并入此处。
技术领域
本公开属于医药化学领域,具体的,本公开涉及嘧啶二酮类化合物,更具体的,本公开涉及一种嘧啶二酮类化合物及其制备方法,以及其在制备药物中的用途。
背景技术
CD73又称为胞外5’-核苷酸水解酶,属于金属磷酸酯酶超家族的外切核酸酶,是一种外周糖蛋白,其主要形式是通过糖基磷脂酰肌醇(GPI)锚定在质膜上,分子量为70KD,由NT5E基因编码。CD73广泛表达于不同组织的细胞表面,包括脑、肺、心、脾、淋巴结、肾、结肠、血管内皮和骨髓;各种免疫细胞也有表达,包括巨噬细胞、中性粒细胞、髓系抑制细胞(MDSCs)、树突状细胞(DC)、自然杀伤细胞(NK)和调节性T细胞(Treg)(Soleimani A等人,Biochimie,2020,176:21-30.);多种肿瘤细胞也有高表达的CD73,如:黑色素瘤、乳腺癌、胰腺癌、卵巢癌、结肠癌和前列腺癌等(Gao Z等人,Biomed Res Int,2014,2014:460654.)。CD73也以可溶性形式(sCD73)存在于包括血清在内的生物体液中,并且保存了全酶活性。
CD73主要通过水解AMP(单磷酸腺苷)产生胞外腺苷(ADO)来发挥生理、病理作用,ADO通过与4个G蛋白偶联受体(GPCRs):A1腺苷受体(A1AR)、A2A腺苷受体(A2AR)、A2B腺苷受体(A2BR)和A3腺苷受体(A3AR)来发挥作用,其中起主要作用的是A2AR(Linden J等人,Annu.Rev.Immunol.,2019,37:325-347.)。腺苷受体(ARs)不仅在肿瘤细胞中表达,在肿瘤微环境中浸润的免疫细胞和血管内皮细胞的细胞表面也有表达,ADO通过与受体结合后,产生多种免疫抑制与促肿瘤作用。
CD73与肿瘤的生长、血管生成和转移密切相关。在正常生理条件下,细胞外ADO水平在20至300nM之间,但在肿瘤微环境下,则升高维持至微摩尔水平(30-100μM),而胞外高ADO浓度主要由CD73水解AMP产生所影响。研究表明癌症患者血浆中可溶性的CD73(sCD73)与健康人相比其水平增加(Klemens M R等人,Biochem.Biophys.Res.Commun.,1990,172:1371-7..)。在胃肠道间质瘤中,肿瘤浸润的NK细胞表达更高水平的CD73,而NK细胞中A2AR信号的缺失可以改善CD73 +肿瘤转移,增强抗肿瘤免疫反应(Young A等人,Cancer Cell.2016;30(3):391-403.)。与正常胰腺组织相比,CD73在胰腺导管癌(PDAC)中表达上调,并且与肿瘤大小、淋巴结转移、转移和不良预后相关(Harvey Jerry B等人,Front Immunol,2020,11:508.)。ORIC公司的临床前研究中,CD73选择性抑制剂ORIC-533显著降低了肿瘤微环境的ADO浓度,同时减小了肿瘤体积。这些研究结果都表明,CD73在多种肿瘤中表达上调,抑制CD73可能能降低ADO浓度,进而抑制肿瘤的生长、转移。
CD73抑制剂除了单独使用,能通过解除免疫抑制来阻断肿瘤生长,还能与其他靶向疗法和/或免疫疗法、放疗联用,来增加抗肿瘤效果。在几种小鼠的肿瘤模型中,抗CD73与抗PD-L1(程序性死亡受体-配体1)和/或抗CTLA-4(细胞毒性T淋巴细胞相关蛋白4)抗体联合治疗比单独使用抗PD-L1和/或抗CTLA-4抗体治疗更有效(Allard B等人,Clin.Cancer Res.,2013,19:5626-35.);接受PD-1免疫治疗的黑色素瘤患者的CD73水平被发现上调,而在抗PD-1治疗后,胶质母细胞瘤患者中持续存在独特的CD73高巨噬细胞群,CD73缺陷增强抗PD-1和抗CTLA-4在小鼠胶质母细胞瘤模型中的疗效(Goswami S等人,Nat.Med.,2020,26:39-46.);放疗导致部分肿瘤细胞破坏,使胞内的大量ATP释放至胞外,在肿瘤细胞表面或游离的CD73作用下,转变为腺苷,产生免疫抑制作用,这被认为是部分患者放疗后预后不良的原因之一,因此CD73抑制剂与放疗联用可能会产生协同作用(Wennerberg E等人,Cancer Immunol Res,2020,8:465-478.)。
目前一些抗CD73单抗(MEDI9447、BMS986179、SRF373/NZV930、CPI-006/CPX-006、TJ004309)和选择性小分子抑制剂(LY3475070、AB680)已进入临床阶段,部分实验取得了令人鼓舞的早期结果(NCT02754141),CD73抑制可能是治疗肿瘤的有希望的方法。

本公开的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位素。例如,可用放射性同位素标记化合物,比如氘( 2H),氚( 3H),碘-125( 125I)或C-14( 14C)。本公开的化合物的所有同位素组成的变换,无论放射性与否,都包括在本公开的范围之内。
