  • XLA X-linked agammaglobulinemia
  • BTK is a key regulator of B cell receptor (BCR) signal transduction pathway, plays an important role in B cell activation, proliferation, differentiation and survival, and is closely related to a variety of B cell tumors and autoimmune diseases.
  • BCR B cell receptor
  • the BTK structure contains 5 main domains, namely the PH domain (Pleckstrin homology), the TH domain (Tec homology), the SH3 domain (Src homology 3), the SH2 domain (Src homology 2) and the SH1 domain ( Src homology1).
  • Activation (phosphorylation) of BTK occurs initially in the activation loop in the SH1 domain, and further activation occurs in the SH2 and SH3 domains that contain major autophosphorylation sites; these SH domains also contain BTK for nucleocytoplasmic shuttling Required nuclear localization signal (NLS) and nuclear export sequence (NES).
  • NLS nucleocytoplasmic shuttling Required nuclear localization signal
  • NES nuclear export sequence
  • BTK plays an irreplaceable role in the generation of B lymphocytes. It can control the development and differentiation of B cells by activating positive cell cycle regulators and differentiation factors, and can also regulate pro-apoptotic and anti-apoptotic proteins. expression to control B cell survival and proliferation. Sustained activation of BTK is a prerequisite for the development of chronic lymphocytic leukemia (CLL); abnormal BCR-BTK signaling promotes the survival of activated B-cell subtypes in diffuse large B-cell lymphoma (DLBCL). Gain-of-function mutations in BTK have also been identified in colorectal cancer, acute lymphoblastic leukemia (ALL), and chronic myeloid leukemia (CML). It can be seen that the abnormal activation of BTK-dependent pathway has been proved to be closely related to the occurrence and development of various tumors.

  • Some studies have also investigated the efficacy and inferiority of autologous hematopoietic stem cell transplantation and whole-brain radiotherapy in PCNSL consolidation therapy. Regardless of the treatment option, the prognosis is poor.
  • BBB blood brain barrier
  • conventional immunochemotherapy is difficult to penetrate and the efficacy is poor.
  • the efficacy of drugs for the treatment of primary or secondary CNS invasion depends on their distribution in the brain after crossing the blood-brain barrier. Only lipophilic molecules can easily pass through the BBB by passive diffusion.

一种作为可透脑的BTK或HER2抑制剂的化合物及其制备方法与用途
本申请要求于2020年07月15日提交中国专利局、申请号为202010679776.6、发明名称为“一种作为BTK抑制剂的化合物及其制备方法与用途”的中国专利申请的优先权,并且要求于2020年11月25日提交中国专利局、申请号为202011337022.9、发明名称为“一种作为BTK抑制剂的化合物及其制备方法与用途”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及医药技术领域,特别是涉及一种具有良好透脑性的BTK或HER2蛋白质激酶抑制剂的化合物及其制备方法与用途。
背景技术
布鲁顿酪氨酸蛋白激酶(BTK)是非受体蛋白酪酸激酶Tec家族的成员,主要表达于多种造血细胞系。Tec家族是人类非受体激酶中仅次于Src家族的第2大家族,其主要成员包括BTK、BMX(etk)、ITK、TEC和TXK(RLK)。在1993年,BTK被确定为人X-连锁无丙种球蛋白血症(X-1inked agammaglobulinemia,XLA)中的缺陷蛋白。BTK是B细胞受体(BCR)信号转导通路的关键调节因子,在B细胞激活、增殖、分化和存活过程中有着重要的作用,与多种B细胞肿瘤及自身免疫性疾病密切相关。
BTK结构中包含5个主要结构域,分别是PH结构域(Pleckstrin homology),TH结构域(Tec homology),SH3结构域(Src homology 3),SH2结构域(Src homology 2)和SHl结构域(Src homology1)。BTK的活化(磷酸化)最初发生在SHl结构域中的活化环中,进一步的活化发生在包含主要自磷酸化位点的SH2及SH3结构域中;这些SH结构域也包含BTK进行核质穿梭所需要的核定位信号(NLS)及核输出序列(NES)。
BTK在B淋巴细胞的生成过程中起着不可替代的作用,其可以通过激活细胞周期正向调控因子和分化因子来控制B细胞的发育、分化,也能通过调节促凋亡和抗凋亡蛋白的表达来控制B细胞的存活和增殖。BTK的持续激活是慢性淋巴细胞白血病(CLL)发展的一个先决条件;BCR-BTK信号传递异常会促进弥漫性大B细胞淋巴瘤(DLBCL)中活化B细胞亚型的存活。BTK功能 获得型突变也已在大肠癌、急性淋巴细胞白血病(ALL)、慢性粒细胞白血病(CML)中得到确证。可见,BTK依赖型通路的异常激活被证明与多种肿瘤的发生发展密切相关。
目前已批准上市的不可逆BTK抑制剂,如伊布替尼(Ibrutinib)、阿卡替尼(acalabrutinib)、赞布替尼(Zanubrutinib),都是可选择性地与BTK的半胱氨酸残基(Cys-481)形成不可逆的共价键结合,抑制BTK活性达到治疗相关疾病的目的。然而,一部分癌症患者会对第一代BTK抑制剂产生耐药,从而出现未满足的新的临床需求。有研究表明,BTK-C481S突变是与此相关的主要耐药机制之一,因此,能够靶向抑制BTK-C481S突变型的药物有望提供新的治疗方案。例如,ARQ-531就是一种口服生物可用的、有效的、可逆的野生型和C481S突变的BTK双重抑制剂;ARQ-531初期临床结果表明了其对C481S突变的BTK患者的有效性。
原发中枢神经系统淋巴瘤(PCNSL)年发病率约为0.47/10万,中国每年有超过1万人患病。经过几十年的治疗发展,截至目前,一线治疗方案以大剂量甲氨蝶呤(high-dose methotrexate,HD-MTX)为基础诱导化疗,实现影像学完全缓解(complete response,CR),全脑放疗(whole-brain radiotherapy,WBRT)作为巩固治疗,此方案中位OS可达30~50个月。但该方案会导致严重神经毒性,且毒性随着病人年龄和放疗剂量增加而增加,表现为记忆力下降、认知功能损伤、步态障碍、痴呆等症状,严重影响病人生活质量。也有研究探讨了自体造血干细胞移植与全脑放疗在PCNSL巩固治疗中的疗效优劣性,结果显示两者并无差异,需指出的是,全脑放疗对于患者的脑功能具有不可逆性的损伤。不论哪种治疗方案,预后都很差。
由于血脑屏障(blood brain barrier,BBB)的存在,常规免疫化疗难以渗透,疗效较差。治疗原发性或继发性CNS侵犯的药物疗效取决于其通过血脑屏障后在大脑中的分布,仅亲脂性分子能被动扩散轻易穿过BBB,常规免疫化疗如利妥昔单抗属于单克隆抗体,分子量较大,难以穿透血脑屏障,故无法发挥全部疗效。
随着PCNSL的发病机制越来越被深入研究,近年来针对BCR通路分子特异性靶向药物的突破性进展给这类患者带来新的治疗选择。Bruton’s酪氨酸激酶(BTK)是一种连接BCR信号通路和NF-κB信号通路的激酶,是治疗 ABC-DLBCL抑制的基本靶点,BTK抑制剂是一种选择性的药物,可直接作用于BCR通路中MYD88和CD79B,而中枢神经系统淋巴瘤中BCR信号通路突变常常是以MYD88和CD79B为主。根据WHO2008分类诊断PCNSL,并且必须要免疫组化的结果,主要标记包括所有的B细胞标志(CD19,CD20,PAX5)、BCL6、MUM1/IRF4和CD10。中枢神经系统恶性肿瘤NCCN指南(2020.V1)中推荐BTKi应用于复发难治PCNSL。
2020年3月,BTK抑制剂Velexbru(Tirabrutinib hydrochloride)在日本获得批准,用于治疗复发性或难治性原发性中枢神经系统淋巴瘤(PCNSL),Velexbru是全球第一个被批准用于治疗复发性或难治性PCNSL的BTK抑制剂。结果显示,经Velexbru治疗后,52.9%的患者得到了有效缓解。Tirabrutinib在复发/难治中枢神经系统淋巴瘤中的I/II期研究,共纳入44例复发/难治性CNSL,第1阶段使用3+3剂量递增设计,接受320和480mg的tirabrutinib每日一次治疗(QD),在28天内评估剂量限制性毒性(DLT);第2阶段在禁食条件下给予480mg tirabrutinib QD;结果显示:与320mg相比,480mg患者的ORR和PFS均更优,ORR:320mg vs 480mg vs 480mg(禁食条件)=60%vs 100%vs 52.9%,PFS:320mg vs 480mg vs 480mg(禁食条件)为2.1vs.11.1vs 5.8个月。但与320mg组相比,480mg(禁食组)的ORR较低可能是由于患者特征的差异造成的。Tirabrutinib各剂量下血浆中药物浓度相当;Tirabrutinib在4个不同时间点,相比320mg,480mg组CSF谷浓度较高,脑脊液浓度随血药浓度的增加而增加;可见中枢神经系统淋巴瘤疗效与BTKi在脑脊液(CSF)中的药物浓度相关。
PCNSL的治疗药物有限,PFS及OS远未达到预期。国外已经有一代不可逆BTK抑制剂(Tirabrutinib)批准用于该病的治疗,但该药物对BTK蛋白活性较弱、临床剂量过高(480mg每天一次)、副作用明显,病人的顺应性较差,且存在服用一段时间后会由于C481S突变而产生耐药的风险。
研究显示,BTK抑制剂还可用于自身免疫性疾病如类风湿性关节炎、多发性硬化症(MS)、银屑病等自身免疫性疾病。其中多发性硬化症的发病原理与脑部的病变有直接的关系。2019年,全球多发性硬化症药物市场规模为250亿美元,预计2027年将达到406.6亿美元,预测期间复合年增长率将为7.1%。临床和经济研究数据显示,MS的年治疗费用为28,000美元。BTK作为B细胞受体信号通路中的一个关键激酶,对B淋巴细胞、巨噬细胞及小胶质细胞 等参与MS病理过程的免疫细胞的发育和功能都很重要。因此,BTK抑制剂有望为MS等自身免疫性疾病的治疗提供新颖的治疗选择。
HER2(人表皮生长因子受体-2)也称ERBB2,位于17号染色体,属于原癌基因。其编码产物HER2蛋白是具有酪氨酸蛋白激酶活性的跨膜蛋白,属于EGFR家族成员之一。它在多种癌症中过度表达,包括乳腺癌、卵巢癌和胃癌等等。HER2介导细胞生长,分化和存活,能促进癌细胞的侵袭性扩散。
大约有15%至20%的乳腺癌是HER2阳性(HER2+)。与HER2阴性癌症相比,HER2+肿瘤更具攻击性,并与较短的生存时间、较差的总体存活率、更高的复发风险以及中枢神经系统疾病(脑转移)有关。大约30%至50%的HER2+乳腺癌患者会随着时间的推移发生脑转移。
2018年GLOBOCAN统计报告显示,全球乳腺癌新增人数接近210万例,发病率为27.5/10万,占所有种类肿瘤发病人数的11.6%。从全球新增发病人数和死亡人数的对比情况来看,乳腺癌是全球女性的第一大癌症杀手,其发病率和死亡率均最高。我国乳腺癌发病率位居女性恶性肿瘤的第一位,高达43/10万。2018年中国乳腺癌新增接近36.8万例,乳癌药金额达400亿元。中国乳腺癌发病率的增速是全球平均增速的两倍(每年增加30余万),在全球排第一。HER2阳性的乳腺癌脑转移患者任无有效疗法,死亡率居高不下(每10万人中有10位死于乳腺癌。
Tukysa(tucatinib)是一种小分子口服酪氨酸激酶抑制剂(TKI),对HER2具有优秀的靶向选择性。2019年曾被FDA授予突破性疗法资格(BTD),除了获得突破性疗法资格,该药物还于2017年获得快速通道资格、孤儿药资格。与曲妥珠单抗和卡培他滨联联用,用于治疗接受过曲妥珠单抗、帕妥珠单抗、T-DM1(ado-trastuzumab emtansine)治疗的局部晚期、不可切除性或转移性(包括伴有脑转移)HER2阳性乳腺癌患者。

现有技术中,ARQ-531的抑制活性仍有待提升,其对TMD8、REC-1等细胞抑制活性较差,导致临床剂量过大,副作用较高等问题。另外,ARQ-531的选择性也较差,对TEC、EGFR有较高的抑制活性,容易导致出血、腹泻、湿疹等副作用;再者其药代也不太理想,临床前研究表明,犬PK实验中,生物利用度仅38%。即,ARQ-531在抑制活性、选择性、药代方面都有较大的提升空间。
PCNSL的治疗药物有限,PFS及OS远未达到预期。国外已经有一代不可逆BTK抑制剂(Tirabrutinib)批准用于该病的治疗,但该药物对BTK蛋白活性较弱、临床剂量过高(480mg每天一次)、副作用明显,病人的顺应性较差,且存在服用一段时间后会由于C481S突变而产生耐药的风险。该药物临床剂量高的原因主要有两个,一是该化合物的活性较弱,更重要的是该药物的血脑屏障透过率低,需要更大的剂量才能达到透过血脑屏障的药物的起效浓度。Tirabrutinib在抑制活性、药代、透脑率方面都有很大的提升空间。
Tucatinib是一种小分子口服酪氨酸激酶抑制剂(TKI),对HER2具有优秀的靶向选择性。2019年曾被FDA授予突破性疗法资格(BTD),除了获得突破性疗法资格,该药物还于2017年获得快速通道资格、孤儿药资格。与曲妥珠单抗和卡培他滨联联用,用于治疗接受过曲妥珠单抗、帕妥珠单抗、T-DM1(ado-trastuzumab emtansine)治疗的局部晚期、不可切除性或转移性(包括伴 有脑转移)HER2阳性乳腺癌患者,于2020年4月17日获得美国食品药品监督管理局(FDA)批准上市。该药物临床剂量大,每天两次,300mg一次,副作用明显。文献资料显示,Tucatinib在小鼠中的透脑率不到5%。Tucatinib在药代、透脑率方面有很大的提升空间。
在本发明实施例的体外BTK抑制及HER2抑制激酶活性试验中,可将所述化合物粉末溶解在100%DMSO中,配制成10mM储存液;-20度避光冻存。在激酶反应过程中,受试化合物测试浓度为1μM,在384source板中稀释成100倍终浓度的100%DMSO溶液,3倍稀释化合物,10个浓度。并且,本发明实施例采用所述化合物还进行了肝微粒体稳定性、大鼠PK、大鼠透脑率、药效模型等实验。与现有临床药物(ARQ-531)相比,本发明作为BTK蛋白质激酶抑制剂的化合物,在BTK、BTK(C481S)抑制活性,肝微粒体稳定性、大鼠药代方面、毒性方面具有优势。与现有上市药物Tirabrutinib相比,本发明作为BTK蛋白质激酶抑制剂的化合物,在BTK、BTK(C481S)抑制活性、细胞活性、肝微粒体稳定性、大鼠药代方面、大鼠血脑屏障透过率等方面具有优势。本发明的HER2抑制剂化合物,在HER2抑制活性、BT474细胞活性、NCI-N87细胞活性方面与现有已上市药物Tucatinib相当;在大鼠药代及大鼠血脑屏障透过率方面明显优于Tucatinib。
本发明实施例通过设计并合成了多个目标化合物,具体的制备过程可如下式所示,中间体A(也称式A所示的硼酸或硼酸酯类化合物)、中间体B(式B所示的溴代物)进行Suzuki反应合成中间体C(式C所示中间体),再脱保护得到式II所示结构的化合物。具体的实施例中,由市售的硼酸A或自制的硼酸酯A与自制的溴代物B在钯催化下偶联制得中间体C,中间体C脱保护得到实施例化合物。相比于临床二期药物ARQ-531,本发明该化合物在BTK及BTK(C481S)的抑制活性、肝微粒体稳定性、大鼠药代方面均有明显的提高。
此外,本发明实施例以下合成方法简便,收率较高。
