本发明属于创新药物化学领域,涉及一种氘代异喹啉-氨基嘧啶类化合物、药物组合物及应用。
背景技术
EGFR(Epidermal Growth Factor Receptor)是一种跨膜蛋白,又叫ErbB-1或者HER1,属于表皮生长因子受体家族(ErbBs)。截至目前,人类发现的ErbB家族共有4种亚型,分别是ErbB1(EGFR)、ErbB2(HER2/neu)、ErbB3(HER3)和ErbB4(HER4)。它与所有的酪氨酸激酶一样,都含有胞外区域、跨膜区域和胞内区域这三个区域结构。EGFR以及其胞内的信号传导通路在恶性肿瘤,尤其是非小细胞肺癌、乳腺癌、结肠癌和卵巢癌中高表达。当胞外结构域与特定的配体结合后,如表皮生长因子(EGF)、转化生长因子α(TGF-α)、细胞素和上皮调节蛋白等,EGFR会发生自聚形成同源二聚体或者和其它的ErbB家族成员形成异源二聚体,导致胞质结构域中关键酪氨酸发生残基磷酸化,继而激活下游的信号通路,从而调控细胞的生长、增殖、迁移等过程。EGFR信号转导失调促进肿瘤细胞增殖、血管生成、侵袭、迁移和转移。因此,EGFR已经成为抗肿瘤药物的有效靶点。
第一代EGFR抑制剂,代表药物包括吉非替尼和厄洛替尼,对携带EGFR激活突变L858R和Del 19的非小细胞肺癌患者具有较好的疗效,但是绝大数患者在经过大约一年的治疗后会呈现出不同程度的耐药情况。50%~60%发生耐药原因是患者体内出现EGFR T790M突变。为了解决这一耐药问题,研究人员开发了第二代不可逆EGFR抑制剂,代表药物包括阿法替尼,但是该类EGFR抑制剂对野生型EGFR选择性较低,导致严重的不良反应。因此,研究人员开发了第三代高选择性不可逆EGFR抑制剂,代表药物包括奥希替尼和奥莫替尼。但是用药一段时间后,该类抑制剂引导至EGFR T797S突变,也会出现耐药性。研究人员开发了第四代EGFR抑制剂,包括变构抑制剂和作用于ATP结合口袋的抑制剂。BLU945是一种作用于激酶ATP结合口袋的新型四代抑制剂,该化合物对L858/T790M/T797S和Del19/T790M/T797S具有强效抑制活性,对正常细胞毒性较小,目前进入早期临床阶段。
氘代药物是指将药物分子中的部分氢原子替换为氘。由于氘在药物分子中形状和体积与氢接近,氘代药物一般会保留原来药物的生物活性和选择性。由于C-D键比C-H键更稳定,使得氘代药物在化学反应过程中,C-D键更不容易断裂,其半衰期会延长。自2000年以来,氘代策略便被广泛应用于药物的研究中。

本发明的“药学上可接受的盐”可由含有酸根或碱基的母体化合物通过常规化学方法合成。一般情况下,这样的盐的制备方法是:在水或有机溶剂或两者的混合物中,经由游离酸或碱形式的这些化合物与化学计量的适当的碱或酸反应来制备。一般地,优选醚、乙酸乙酯、乙醇、异丙醇或乙腈等非水介质。

除了盐的形式,本发明所提供的化合物还存在前药形式。本文所描述的化合物的前药容易地在生理条件下发生化学变化从而转化成本发明的化合物。可在体内转化以提供生物活性物质(即式I所示化合物)的任何化合物是在本发明的范围和主旨内的前药。例如,含有羧基的化合物可形成生理上可水解的酯,其通过在体内水解以得到式I所示化合物本身而充当前药。所述前药优选口服给药,这是因为水解在许多情况下主要在消化酶的影响下发生。当酯本身具有活性或水解发生在血液中时,可使用肠胃外给药。

实施例30:AlphaLISA检测细胞内EGFR抑制
表达EGFR突变的Ba/F3细胞悬浮于含有10%牛血清的RPMI 培养基中,细胞密度为1.0 × 106 cells/mL。第二天,收集细胞,并采用新鲜培养基稀释细胞1.25 × 106 cells/m,取40 μL接种于384孔板中,不同浓度的化合物加入到孔板中,37℃下共培养4 h。然后,离心5min(3000 rpm),去掉培养基,破解细胞。采用AlphaLISA SureFire Ultra DetectionKit检测实施例化合物对细胞内EGFR磷酸化抑制活性。
如表2所示,与BLU-945相比,实施例化合物对细胞内磷酸化EGFR的抑制活性均有所提高。

实施例31:抗增殖活性测试
化合物癌细胞抑制活性数据用MTT方法来检测,MTT法又称MTT比色法,是一种检测细胞存活和生长的方法。MTT(黄色的噻唑兰)可透过细胞膜进入细胞内,活细胞线粒体中的琥珀脱氢酶能使外源性MTT还原为难溶于水的蓝紫色的针状Formazan结晶并沉积在细胞中,结晶能被二甲基亚砜(DMSO)溶解,用酶联免疫检测仪在490 nm/570 nm波长处检测其光吸收值,可间接反映活细胞数量。所用细胞系包括:PC9携带突变体Del19;H1975细胞携带L858R/T790M突变;A431细胞野生型具体实验步骤如下:
(1)收集对数生长期细胞,调整细胞悬液浓度,在96孔板中每孔加入100 μL细胞悬液;每孔细胞数量约为7000个,在5% CO2,37 ◦C孵育过夜至细胞完全贴壁;
(2)设置药物浓度梯度,每个浓度梯度设置3个复孔,将药物稀释到对应培养基中至所需终浓度,吸出96孔板中原有培养基,加入配好的含所需终浓度药物的培养基100 μL,在5% CO2,37 ◦C孵育;并同时设置空白组(只含100 μL培养基,不含细胞,后续处理与其他各孔相同)与对照组(含有细胞与培养基);
(3)药物处理至44小时时每孔加入10 μL MTT溶液(5 mg/ml),继续培养4h(药物处理细胞共48小时);
(4)吸干净孔内培养液(如细胞出现悬浮,则先2500 rpm离心5min再吸出培养基)。每孔加入150 μL二甲基亚砜,振荡至结晶物充分溶解。在酶标仪上检测OD 490 nm处各孔的吸光值;
(5)计算抑制率:抑制率=1-(加药组OD值-空白组OD值)/(对照组OD值-空白组OD值)=(对照组OD值-加药组OD值)/(对照组OD值-空白组的OD值);
(6)按上述实验步骤重复三次,得出三次抑制率的平均值,利用IC50计算器算出药物的IC50值。

如表3所示,与BLU-945相同,部分实施例化合物对携带EGFR突变体Del19的PC9和携带双突变体L858R/T790M的H1975细胞具有显著的抑制活性,而对表达野生型EGFR的A431细胞抑制活性较低,这说明实施例化合物对携带EGFR突变体的肿瘤细胞具有强的抑制活性,且毒副作用较低。
实施例32:待测化合物药代动力学性质检测
选用雄性SD大鼠,口服 (2.5 mg/kg)或静脉注射(1 mg/kg)给药,于给药后5min,15min,30min,1h,2 h,4 h,8 h,10 h,24 h,从眼底静脉丛连续取血置于含有肝素的EP管中,离心、取上层血浆进行LC-MS/MS分析,根据测试所得的血药浓度-时间数据,采用WinNonlin软件计算药代动力学参数,计算口服生物利用度。
研究结果表明,BLU-945在大鼠中的口服生物利用度为48%,半衰期2.4 h;化合物S17口服生物利用度提高至65%,半衰期延长至4.9 h,这说明氘代化合物的氘代动力学性质显著改善,可以降低化合物S17的单次给药剂量。
最后有必要说明的是,以上对本发明的具体实施例进行了详细描述,但其只作为范例,本发明并不限制于以上描述的具体实施例。对于本领域技术人员而言,任何对本发明进行的等同修改和替代也都在本发明的范畴之中。因此,在不脱离本发明的精神和范围下所作的均等变换和修改,都应涵盖在本发明的范围内。
