Description
技术领域
本发明属于药物化学领域,具体为一种新型的3-氨基-2,7-二氢吡喃并[4,3-c]吡唑-4,6-二酮类BTK抑制剂以及这种抑制剂的制备方法和用途。
背景技术
肿瘤是一种严重威胁人类健康的常见病和多发病,是由于人体内细胞的不正常增生所导致。肺癌、消化道肿瘤和肝癌是男性最常见的肿瘤,占所有病例的70%以上(肺癌23%、胃癌15.2%、肝癌13.57%、食管癌10.46%、结直肠癌9.39%),而乳腺癌、肺癌、消化道肿瘤和肝癌是女性最常见的肿瘤,占所有病例的60%以上(乳腺癌16.97%、肺癌14.85%、结直肠癌9.68%、胃癌8.53%、肝癌6.17%)。随着中国人口老龄化的加剧,癌症的患病率势必增加。另外环境污染情况也增加了一些癌症的患病率,如淋巴癌。自身免疫性疾病是免疫系统对自身机体的成份发生免疫反应,造成损害而引发疾病。
BTK(brutontyrosinekinase)是一种胞浆蛋白,属于非受体络氨酸激酶Tec家族,其表达于多数的造血细胞中,如B细胞、肥大细胞、巨核细胞等,但在T细胞、NK细胞及浆细胞中不表达。BTK对B细胞受体信号通路起非常关键的作用,对B细胞的增殖、分化和凋亡有重要影响。
在恶性B细胞中,B细胞受体信号通路过度活跃,从而抑制B细胞的正常分化和凋亡,促进异常增殖。已知多种B细胞类型的恶性肿瘤中经常存在BCR通路的异常调节,如弥漫性大B细胞淋巴瘤(DLBCL)、套细胞淋巴瘤(MCL)、慢性淋巴细胞白血病(CLL)、滤泡性淋巴瘤(FL)、华氏巨球蛋白血症(WM)、边缘区淋巴瘤(MZL)、B淋巴母细胞性白血病(B-LBL)和伯基特淋巴瘤(BL)等。
自从BTK抑制剂在1993年第一次被发现之后,针对BTK的药物研究一直没有停止过。BTK抑制剂的适应症仍在不断拓展中,除抗肿瘤外,自身免疫型疾病的应用将是把BTK抑制剂推向另一个市场高度的关键所在。目前国内相继研发BTK的多种小分子抑制剂并且在体内及体外试验中均表现出良好的抗肿瘤作用,除了已上市的药物Ibrutinib和ACP-196,更多新的BTK抑制剂正在研究中,目前进展较快的除BGB-3111之外,CT1530、GS-4059已经进入临床Ⅱ期
目前,针对BTK靶点的肿瘤靶向小分子药物已经研发到了第2代,第一代BTK抑制剂为依鲁替尼(Ibrutinib)于2013年美国上市用于临床治疗复发性或难治性套细胞淋巴瘤(MCL),是靶向BTK的明星药物,Ibrutinib能够抑制恶性增殖的B细胞的生长和转移,同时Ibrutinib是第一个被FDA构批准上市的BTK抑制剂。Ibrutinib除了被用于治疗各种血液疾病,它还用于治疗自身免疫相关疾病包括干细胞移植、移植后的免疫抵抗和关节炎等。但是Ibrutinib在治疗中的响应率并非百分之百,而且疾病会复发,该药物存在着未知的原发性耐药和获得性耐药。随着药物的上市和临床使用,Ibrutinib开始在不同病人体内产生了不同机制的耐药性。获得性耐药迄今为止只有这两个靶点突变的发现,在BCR信号通路中,BTK与ibrutinib的结合位点481位发生了突变Ibrutinib剂量依赖性抑制关节炎模型中的疾病Ibrutinib在临床上的耐药问题越来越多,也出现了许多副作用。
第二代BTK抑制剂Acalabrutinib(ACP-196),ACP-196被称之为第二代BTK抑制剂,就是因为在抑制BTK激酶靶点的基础上还不对其他的激酶产生抑制作用。在2017年8月被FDA批准用于套细胞淋巴瘤(MCL)的治疗,目前也还有许多适应症正处于临床,例如:慢性淋巴白血病(CLL)正处于临床三期;一些实体瘤比如非小细胞肺癌,头颈癌等正处于临床二期,发展非常迅速。ACP-196对关节炎的治疗目前也处于临床二是因为Ibrutinib的脱靶效应导致的。因此第二代选择性更好的BTK抑制剂开始应运而期阶段,由于其的高选择性,副作用少,在治疗例如自身免疫疾病之类的慢性病具有良好的发展前景。
目前已知BTK抑制剂的选择性不理想,除了抑制BTK,还抑制其他多种激酶(如ETK,EGF,BLK,FGR,HCK,YES,BRK和JAK3等),从而产生较多的副作用;同时,BTK结合位点发生突变后往往会导致耐药性的产生。因此临床上需要更多的BTK抑制剂,用于治疗肿瘤等疾病,同时可以克服此类不良事件。
本发明设计合成一种新型的3-氨基-2,7-二氢吡喃并[4,3-c]吡唑-4,6-二酮类化合物,体外实验表明这种化合物对癌细胞具有较好的细胞毒性,其中化合物TM10对肺癌细胞的IC50达到0.86μM,是一种具有开发为新型抗癌药物的化合物;在制备方法上,本发明通过简单方法高效地合成了关键中间体及其目标化合物。
发明内容
本发明的目的在于对已上市药物依鲁替尼的结构特点分析,结合最新报道的构效关系,哌啶-2,6-二酮N2位取代基R1的不同对Btk酶活性影响不大,且R1朝向酶的一个亲水口袋,引入不同的亲水性基团(如:酸、酰胺、胺)可以调节化合物的理化性质。N9位取代基R2的空间取向朝向激酶的gatekeeper区域,并与特定的残基相互作用在Tec家族中,不同激酶的gatekeeper区域产生相互作用的氨基酸残基存在差异:
期望设计合成更高细胞毒性化合物,发挥抗癌效果,并具备成药性潜质。细胞毒性实验发现本发明化合物对多种癌细胞具有较强的体外抑制作用。

对癌细胞的体外细胞毒活性测试
为了研究本次实验中所合成的目标化合物抑制肿瘤细胞增殖的能力,我们测定了本发明化合物对淋巴瘤细胞株(Raji)、乳腺癌细胞(MCF7)、白血病细胞(K562)和头颈部鳞癌细胞(HN5)四种肿瘤细胞的体外细胞毒性。实验采用的检测方法是标准的MTT法。
实验方法具体为:
淋巴瘤细胞株、乳腺癌细胞、白血病细胞、头颈部鳞癌细胞(上海和序生物科技有限公司)四种肿瘤细胞经胰酶消化处理10min后弃掉液体,用5%血清的培养液吹打,调细胞浓度为300~400个/μL,依次加入药物,预留只含培养液的空白组,在培养箱中培养24h。弃掉上清液,将稀释好的不同浓度的目标化合物加入96孔板(上海卧宏生物科技有限公司),对照组只加细胞液,每组浓度均设置三个副孔,混匀后继续培养36h,观察不同时间段细胞形态变化,细胞与药物充分作用后,每孔加入现配的MTT溶液显色,继续培养6h。弃掉上层液体,100μLDMSO溶解形成紫色结晶,选定490nm,酶标仪(HBS-1096A酶标分析仪,南京德铁实验设备有限公司)测定吸光度。通过公式:细胞抑制率(%)=(1-A实验/A对照)×100%,求出IC50值(用细胞存活率对剂量对数作图法)。
化合物TM1~8对淋巴瘤细胞株(Raji)、乳腺癌细胞(MCF7)、白血病细胞(K562)和头颈部鳞癌细胞(HN5)四种肿瘤细胞增殖抑制的体外毒性试验结果见表1。
