Definitions

  • the present invention relates to a five-membered heterocyclic compound and a pharmaceutical composition and application thereof, and in particular to a five-membered heterocyclic compound having inhibitory activity against PD-1/PD-L1 protein-protein interaction and a pharmaceutical composition and application thereof.
  • Immune escape is a basic biological characteristic of malignant tumors. Under normal physiological conditions, the human immune system can identify foreign molecules and eliminate them in a timely manner. However, for tumor patients, due to the low immune capacity of the body and the special biological characteristics of tumor cells, tumor cells can escape the recognition and killing of the immune system through various mechanisms, and eventually occur and develop in the body. Tumor immune escape is a complex pathological process, among which the escape mechanism mediated by immune checkpoints has attracted much attention.
  • Immune checkpoints are regulators of the human immune system. They are composed of a series of co-stimulatory molecules and co-inhibitory molecules, and play an important regulatory role in the body's immune system.
  • the co-stimulatory molecules of immune checkpoints mainly include CD27, CD40, OX40, GITR, CD137, OX40 and ICOS, while the co-inhibitory molecules are mainly CTLA-4, PD-1, PD-L1, PD-L2, TIM-3, VISTA and IDO.
  • co-stimulatory molecules can enhance the body's immune response, which is beneficial for immune cells to eliminate foreign molecules, while co-inhibitory molecules play a negative regulatory role in the immune response, thereby maintaining the body's immune homeostasis and avoiding excessive immunity and causing damage to the host's normal tissues.
  • tumor cells can use immune checkpoints to achieve immune escape.
  • the common escape mechanism is that tumor cells induce themselves, antigen presenting cells (APCs) and T lymphocytes to overexpress co-inhibitory molecules on their surfaces, thereby inhibiting the activation of T lymphocytes.
  • APCs antigen presenting cells
  • T lymphocytes to overexpress co-inhibitory molecules on their surfaces, thereby inhibiting the activation of T lymphocytes.
  • programmed death receptor 1 (PD-1) and its ligands PD-L1/2 have received widespread attention as important co-inhibitory molecules in immune checkpoints.
  • PD-1/PD-L1 has been fully confirmed as a target for tumor immunotherapy.
  • PD-1 can also be expressed at low levels in CD4 - CD8 - T cells, B cells, dendritic cells (DCs), and natural killer (NK) cells in the thymus.
  • PD-1 has two ligands, of which PD-L1 is mainly expressed in mature T cells, B cells, and some non-hematopoietic cells, but PD-L1 can be expressed on a variety of cells under the induction of inflammatory factors (such as IFN- ⁇ , TNF- ⁇ , and VEGF).
  • the expression range of PD-L2 is relatively narrow, mainly expressed in macrophages and DC cells.
  • PD-1 When PD-1 binds to its ligand, it causes tyrosine phosphorylation in the ITSM domain of the cytoplasmic region, thereby recruiting SHP-2 phosphatases near the TCR, inhibiting the activation of the TCR proximal kinase, resulting in a decrease in the phosphorylation level of ZAP-70 mediated by TCR-CD3 molecules and Lck, thereby activating its downstream signaling pathway.
  • the negative regulation of PD-1/PD-L on immunity is mainly through inhibiting the PI3K-AKT and RAS signaling pathways, blocking the activation of transcription factors that play an important role in T cell activation, proliferation, function and survival, such as activator protein-1 (AP-1), nuclear factor of activated T cells (NFAT) and NF- ⁇ B.
  • transcription factors that play an important role in T cell activation, proliferation, function and survival, such as activator protein-1 (AP-1), nuclear factor of activated T cells (NFAT) and NF- ⁇ B.
  • AP-1 activator protein-1
  • NFAT nuclear factor of activated T cells
  • NF- ⁇ B NF- ⁇ B
  • the PD-1/PD-L signaling pathway can induce and maintain the tolerance of peripheral tissues during immune responses to prevent excessive immune responses in tissues.
  • excessive activation of the PD-1/PD-L signaling pathway will inhibit the secretion of immunostimulatory factors such as IFN- ⁇ , TNF- ⁇ and IL-2 and the expression of survival proteins.
  • immunostimulatory factors such as IFN- ⁇ , TNF- ⁇ and IL-2 and the expression of survival proteins.
  • a large number of studies have shown that abnormalities in the PD-1/PD-L signaling pathway are closely related to viral infections, diabetes, neurodegenerative diseases, organ transplant rejection and autoimmune diseases.
  • abnormalities in the PD-1/PD-L signaling pathway are closely related to the occurrence, development, and poor prognosis of a variety of human tumors.
  • tumor cells can survive by anti-apoptotic signals and inhibiting the activity of antigen-specific T lymphocytes.
  • blocking the PD-1/PD-L signaling pathway using PD-1 or PD-L1 antibodies can inhibit the growth of tumor cells.
  • T lymphocyte signal transduction It mainly reverses the effects on T lymphocyte signal transduction, reactivates T lymphocytes, promotes the generation of effector T lymphocytes and memory T lymphocytes, and inhibits the differentiation of regulatory T lymphocytes, ultimately enhancing the immune killing ability of T lymphocytes in the tumor microenvironment, thereby achieving the purpose of treating tumors.
  • PD-1/PD-L1 monoclonal antibody drugs such as Keytruda and Opdivo have been launched in the world, which are used in the clinical treatment of malignant melanoma, non-small cell lung cancer, gastric cancer, liver cancer, kidney cancer, bladder cancer and other solid tumors and blood cancers, greatly improving the prognosis of cancer patients and breaking the treatment bottleneck of many types of cancer.
  • PD-1/PD-L1 monoclonal antibody drugs have some obvious shortcomings.
  • small molecule drugs with their unique pharmacokinetic and pharmacodynamic properties, coupled with their low production costs, are expected to solve the defects of monoclonal antibody drugs, so the development of PD-1/PD-L1 small molecule inhibitors has important application value.
  • the development of such small molecule inhibitors is full of challenges, resulting in them still being in the early stages of development, far behind monoclonal antibody drugs. Therefore, there is an urgent need to develop new PD-L1 small molecule inhibitors with high activity and good drugability.
  • the present invention aims to provide a small molecule drug and pharmaceutical composition and application with significant PD-L1 inhibitory activity.

Description

五元杂环类化合物及其药物组合物与应用 技术领域
本发明涉及一种五元杂环类化合物及其药物组合物与应用,尤其涉及一种针对PD-1/PD-L1蛋白-蛋白相互作用具有抑制活性的五元杂环类化合物及其药物组合物与应用。
背景技术
免疫逃逸是恶性肿瘤的一种基本生物学特征。在正常生理条件下,人体的免疫系统能够识别出异己分子并及时进行清除。但对于肿瘤患者而言,由于机体免疫能力低下和肿瘤细胞特殊的生物学特征,使得肿瘤细胞可以通过各种不同的机制逃避免疫系统的识别和杀灭,最终得以在体内发生与发展。肿瘤免疫逃逸是一个复杂的病理过程,其中由免疫检查点介导的逃逸机制深受人们关注。
免疫检查点是人体内免疫系统的调节器,由一系列共刺激分子和共抑制分子组成,在机体免疫系统中起重要的调控作用。免疫检查点的共刺激分子主要包括CD27、CD40、OX40、GITR、CD137、OX40和ICOS等,而共抑制分子则主要为CTLA-4、PD-1、PD-L1、PD-L2、TIM-3、VISTA和IDO等。其中,共刺激分子可以增强机体的免疫应答,从而有利于免疫细胞清除异己分子,而共抑制分子则对免疫应答起着负性调节作用,从而维护机体的免疫稳态,避免过度免疫而造成宿主正常组织的损伤。然而,肿瘤细胞却能够利用免疫检查点而实现免疫逃避。其中,常见的逃避机制便是肿瘤细胞通过诱导自身、抗原呈递细胞(APC)和T淋巴细胞等表面过度表达共抑制分子,从而抑制T淋巴细胞的激活。其中,程序性死亡受体1(PD-1)及其配体PD-L1/2作为免疫检查点中重要的共抑制分子受到广泛关注,目前PD-1/PD-L1作为肿瘤免疫治疗的靶点已得到充分的确证。
PD-1除了表达在成熟的T细胞外,还可以低水平表达在胸腺内的CD4-CD8-T细胞、B细胞、树突状细胞(DC)和自然杀伤(NK)细胞。PD-1有两个配体,其中PD-L1主要表达在成熟的T细胞、B细胞以及一些非造血类型细胞,但PD-L1可以在炎症因子(如IFN-γ、TNF-α和VEGF)的诱导下于多种细胞上表达。PD-L2表达范围相对较窄,主要是在巨噬细胞和DC细胞中表达。当PD-1与其配体结合后会引起胞质区ITSM结构域中的酪氨酸发生磷酸化,从而通过招募TCR附近的SHP-2磷酸酶,抑制TCR近端激酶的活化,导致TCR-CD3分子和Lck介导的ZAP-70磷酸化水平减弱,进而激活其下游信号通路。PD-1/PD-L对免疫的负调控主要是通过抑制PI3K-AKT和RAS信号通路,阻断对T细胞激活、增殖、功能和生存等具有重要作用的转录因子的活化,如激活蛋白-1(AP-1)、活化T细胞的核因子(NFAT)和NF-κB。另外,还可以通过上调转录因子BATF的表达来抑制T细胞功能。
在正常生理条件下,PD-1/PD-L信号通路可以诱导并维持外周组织在免疫反应时的耐受性,以防止组织发生过度免疫应答。当机体处于病理状态下,PD-1/PD-L信号通路过度激活会抑制免疫刺激因子如IFN-γ、TNF-α和IL-2的分泌与存活蛋白的表达。大量研究表明,PD-1/PD-L信号通路的异常与病毒感染、糖尿病、神经变性疾病、器官移植排斥和自身免疫性疾病等密切相关。
此外,众多研究表明,PD-1/PD-L信号通路的异常与人类多种肿瘤的发生、发展和预后不良存在密切的关系。在肿瘤微环境中,当PD-1/PD-L信号通路被过度激活后,肿瘤细胞可以通过抗凋亡信号以及抑制抗原特异性T淋巴细胞的活性而获得生存。另外,使用PD-1或PD-L1抗体阻断PD-1/PD-L信号通路则能够抑制肿瘤细胞的生长。其主要是通过逆转对T淋巴细胞信号转导的影响,重新激活T淋巴细胞,同时促进效应T淋巴细胞和记忆T淋巴细胞的生成以及抑制调节性T淋巴细胞的分化,最终增强肿瘤微环境内T淋巴细胞的免疫杀伤能力,从而达到治疗肿瘤的目的。
目前全球已经有Keytruda和Opdivo等10多款PD-1/PD-L1单克隆抗体药物上市,应用于临床治疗恶性黑色素瘤、非小细胞肺癌、胃癌、肝癌、肾癌、膀胱癌等多种实体肿瘤和血液癌症,极大地改善了肿瘤患者预后,打破了许多种类癌症的治疗瓶颈。然而,PD-1/PD-L1单抗药物存在一些明显的不足。例如,由于其原发性和/或获得性耐药,导致大多数肿瘤患者不能从中获益;由于其缺乏口服生物利用度,无法口服给药,患者依从性差;再加上本身具有的免疫原性容易导致患者出现药源性免疫相关不良事件(irAEs);此外,由于单克隆抗体的制备和纯化难度大,而且运输不便,导致治疗成本高。这些问题都限制了PD-1/PD-L1单抗药物的临床应用。值得一提的是,小分子药物凭借其独有的药代动力学性质和药效学特性,加上其生产成本低,有望解决单抗药物存在的缺陷,因此研发PD-1/PD-L1小分子抑制剂具有重要应用价值。然而,该类小分子抑制剂的研发充满着挑战,导致其目前仍处于前期研发阶段,远远落后于单抗药物,因此急需研发活性高且成药性好的新型PD-L1小分子抑制剂。

2.2实验结果
实验结果如图1所示。结果表明,与模型组相比,本发明化合物77在各种检测浓度下对Lewis肺癌细胞的活力均没有明显的影响,说明本发明化合物无明显的细胞毒性。
3、本发明化合物对细胞因子INF-γ释放的影响
细胞因子是一类具有效应及调节双重作用的独特分子,在淋巴细胞应答中具有重要的免疫调节作用。活化的人外周血单个核细胞(PBMC)可以释放IFN-γ、IL-2和TNF-α等细胞因子,而当PBMC膜上表达的PD-1与其配体PD-L1结合后将会抑制细胞因子的释放。本实验的目的是检测本发明化合物是否能逆转PD-1/PD-L1抑制PBMC分泌INF-γ的能力。
3.1实验方法
使用人淋巴细胞分离液提取人外周血单个核细胞(PBMC),接种到24孔板,加入终浓度1μg/mL的anti-CD3/anti-CD28,终浓度为2μg/mL配体蛋白和不同剂量的化合物,48h后离心取上清100μL,使用达科为公司的INF-γ酶联免疫吸附试剂盒检测上清中INF-γ的表达量。

4、本发明化合物的药代动力学实验
良好的药物代谢动力学性质是评价一个候选药物成药性的必不可少的参数。为了检验本发明化合物是否具有良好的成药性,选取本发明化合物77开展大鼠体内药代动力学实验,BMS-1018为阳性药。
4.1实验方法
实验所选动物为SD大鼠,体重200~250克。化合物77和BMS-1018的给药剂量分别为口服10mg/kg和静脉注射2mg/kg,口服组为3只大鼠,静脉注射组为5只大鼠。给药后采集9个时间点的血浆样品,计算药代动力学参数。
实验当天将ICR雄性小鼠按体重随机分为组,每组3只。给药前1天禁食不禁水12~14h,给药后4h给食。每只动物每次通过眼眶取0.030mL血液,EDTAK2抗凝,采集时间点为:(1)I.G.组:0.0833,0.25,0.5,1,2,4,6,8,24h。(2)I.V.组:给予受试物后0.25,0.5,1,2,4,6,8,24h。血液样本采集后置于冰上,并于30分钟内离心分离血浆,分析前存放于-80℃。
取样品10μL(从冰箱-80℃中取出样品,室温自然溶化后涡旋30秒)至1.5mL离心管中,加入100μL内标溶液(5.0ng/mL维拉帕米,30.0ng/mL丁螺环酮和60.0ng/mL地塞米松乙腈溶液),涡旋60秒后离心3分钟(12000rpm);取上清液75μL移至装有等体积水的96孔进样板上,振荡混匀后LC-MS/MS进样分析,进样量为10μL。
数据采集及控制系统软件为Analyst1.5.1软件。图谱样品峰积分方式为自动积分;采用样品峰面积和内标峰面积的比值作为指标,和样品的浓度进行回归。回归方式:线性回归,权重系数为1/X2。药代动力学参数用WinNonlin Professional v6.3(Pharsight,USA)用非房室模型分析处理。Cmax为实测的最大血药浓度,血药浓度-时间曲线下面积AUC(0→t)由梯形法计算得到,Tmax为给药后血药浓度达峰时间。
4.2实验结果
实验结果如表2所示。从表中可以看出,化合物77具有良好的药代动力学参数,特别是其具有较长半衰期,并且口服生物利用度达到23.94%。值得一提的是,BMS-1018口服给药未能检测到血药浓度,而且其静脉注射的半衰期仅为0.53h。这些实验结果表明本发明化合物具有良好的药代动力学性质。
表2.大鼠体内药代动力学实验结果
5、本发明化合物的体内药效学评价
增殖细胞核抗原(PCNA)是真核细胞DNA合成所必需的一种核蛋白,检测PCNA可以客观评价肿瘤细胞的增殖状态。为此,在开展体内药效学评价过程中,利用免疫组化和TUNEL分析检测肿瘤组织中的T淋巴细胞的浸润以及IFN-γ和PCNA水平。以BMS-1018作阳性对照组。
5.1实验方法
小鼠的培养:选择7~8周的雌鼠,在SPF级动物饲养室饲养一周,每只小鼠体重大约在18~20g。
肿瘤细胞的处理:采集处于对数生长期的肿瘤细胞,180g离心5min(4℃),使用预冷的PBS洗2次,吹打均匀,终细胞浓度为1×107/mL,冰浴备用。
肿瘤细胞的移植:将Lewis肺癌细胞悬浮液接种至BALB/c雌鼠右侧腋窝皮下,接种的肿瘤细胞数为1×106/只。每两天使用游标卡尺测量小鼠肿瘤大小一次,称小鼠体重一次。当肿瘤体积均值达到40mm3左右时,开始给药。
实验分组和给药方法:移植Lewis肺癌细胞的BALB/c雌鼠分为4组,每组6只。模型组(溶剂:PBS+2%的吐温20+2%DMSO,灌胃给药,每天一次),阳性对照组(BMS-1018,灌胃给药,每天一次,剂量:15mg/kg),药物处理组1(化合物77,灌胃给药,每天一次,剂量:5mg/kg),药物处理组2(化合物77,灌胃给药,每天一次,剂量:15mg/kg)。
当肿瘤体积达到一定大小后,结束动物实验。称量小鼠体重,对其进行眼球取血,并对小鼠实施安乐死,剥取肿瘤组织,对肿瘤组织进行称重并拍照。同时,将部分组织置于10%中性固定液中,送样进行石蜡包埋组织、制作石蜡组织切片,并开展H&E染色、TUNEL和免疫组化分析。实验操作参考检测试剂盒说明书。
5.2实验结果
实验结果如图3所示。结果表明,与模型组相比,本发明化合物77在5mg/kg和15mg/kg给药剂量下都能显著抑制Lewis肺癌小鼠移植瘤的生长,呈现剂量依赖性,并且不影响小鼠的体重。此外,在相同给药剂量下,化合物77对移植瘤的抑制活性明显优于对照组BMS-1018。
免疫组化和TUNEL实验结果表明,与模型组相比,化合物77在5mg/kg和15mg/kg剂量下都能够显著促进肿瘤组织中T淋巴细胞的浸润,并且提高IFN-γ的水平,降低PCNA蛋白的表达,而且在5mg/kg剂量下,化合物77逆转PD-1/PD-L1介导的免疫抑制作用强于BMS-1018对照组。
6、本发明化合物对肿瘤微环境T淋巴细胞浸润的影响
T淋巴细胞是人体免疫系统的核心执行者,在肿瘤免疫应答中起重要作用。肿瘤浸润淋巴细胞(TIL)是指那些离开血流进入到肿瘤中的白细胞。当肿瘤微环境中存在大量的肿瘤浸润淋巴细胞时,表明机体启动了对抗肿瘤的免疫反应。PD-1/PD-L1信号通路的激活会抑制抗肿瘤免疫微环境,导致淋巴细胞的浸润减少。本实验的目的分析本发明化合物对肿瘤微环境中T淋巴细胞浸润的影响。
6.1实验方法
取部分实验4中剥取的肿瘤组织,剪碎转入15mL离心管中,加入胶原酶IV(0.5mg/mL)、DNA酶I(0.5mg/mL),37℃消化30min,过滤掉剩余组织碎片,离心重悬细胞后使用不同通道的CD45、CD3、CD4、CD8流式抗体避光染色30min,流式细胞仪检测。
6.2实验结果
实验结果如图4所示。结果表明,与模型组相比,化合物77在5mg/kg和15mg/kg剂量下能够显著促进CD45+白细胞、CD45+CD3+T淋巴细胞、CD8+CD45+CD3+细胞毒性T细胞的浸润,并且呈现剂量依赖性,而对CD4+CD45+CD3+调节性T淋巴细胞的影响很弱。此外,在相同剂量下,化合物77促进淋巴细胞浸润的能力强于BMS-1018,特别是对CD45+CD3+CD8+细胞毒性T淋巴细胞的浸润增加更为突出。这些实验说明本发明的化合物能够有效地逆转PD-1/PD-L1介导的免疫抑制作用,重塑抗肿瘤免疫微环境。
本发明的其他化合物在多种肿瘤类型如CT26、EMT6、B16F1、PAN02、LLC等小鼠移植瘤模型中表现出显著的抗肿瘤作用,而且这些化合物能够促进淋巴细胞对肿瘤微环境的浸润,提高肿瘤组织中IFN-γ的分泌,降低PCNA蛋白的表达。说明本发明化合物能够阻断PD-1/PD-L1介导的免疫抑制作用,激活抗肿瘤免疫应答。
