Description
技术领域
本发明属于医药技术领域,具体涉及一种色原酮类mTOR抑制剂及其药物组合物和应用。
背景技术
肿瘤是影响人类健康的重要疾病,肿瘤治疗主要包括传统的手术治疗、放射治疗、化学治疗、靶向治疗、免疫治疗等治疗方式。随着肿瘤分子生物学与基因组学的发展,人们对肿瘤分子表型的认识也不断加深,肿瘤治疗的策略从既往围绕发病部位和形态病理为核心的系统化疗阶段,逐渐转变为针对驱动基因突变的精准靶向治疗。肿瘤靶向治疗即通过特异性靶向在肿瘤发生和进展中发挥重要作用的分子或信号通路,对肿瘤进行治疗的方法。基于肿瘤特定分子表型给予相应的靶向治疗已成为当前晚期肿瘤治疗的首选方案。靶向药物成为抗肿瘤药物研发的热点。
PI3K/AKT/mTOR信号通路影响恶性肿瘤细胞的增殖、存活、转录、翻译和代谢等过程。PI3K-Akt-mTOR信号通路的异常激活与多种人类肿瘤有关,例如卵巢,乳腺癌,子宫内膜,结直肠和胶质母细胞瘤(Mol.Biol.Cell.,2009,20,1981-1991.)。因此针对该通路中的PI3K、mTOR等激酶的有机小分子激酶抑制剂已成为小分子靶向抗肿瘤药物研发的热点之一。mTOR作为PI3K/Akt下游的重要丝氨酸-苏氨酸蛋白激酶,参与调节细胞生长、增殖、存活和自噬。mTOR信号通路控制着细胞的代谢、生长、增殖和存活,mTOR的持续过度激活会导致细胞代谢增加,持续生长增殖,延长细胞寿命甚至细胞永生,可直接或间接诱发代谢性疾病、癌症和衰老疾病,抑制这种状态可有效延缓或治疗癌症,心血管损伤,以及由mTOR过度激活引起的其他疾病。因此,mTOR抑制剂是研究重点,已开发出许多mTOR抑制剂(图1)。
mTOR抑制剂按蛋白口袋可分为变构抑制剂和ATP竞争性抑制剂。变构mTOR抑制剂主要是雷帕霉素及其衍生物(Rapalogs)。然而,Rapalogs在某些癌症的临床治疗中尚未达到预期的疗效。长期使用该药物后,mTORC1对AKT的负反馈将激活该信号的上游途径,导致耐药性。Rapalogs还具有结构复杂,合成困难,稳定性差和生物利用度低等缺点(Eur.J.Med.Chem.,2020,208(5022):112820.)。尽管变构mTOR抑制剂的发现较早,对Rapalogs的研究已经成熟,但Rapalogs分子量大,手性碳多,合成难度较大,此外,位点修饰有限。ATP竞争性mTOR抑制剂调节mTOR下游信号通路,同时通过与mTOR激酶上游分子竞争mTOR激酶上的ATP结合位点来降低Akt反馈活化,这些抑制剂克服了雷帕霉素的缺点,更容易靶向mTOR结合位点,对肿瘤细胞有更强的生长抑制作用,但如PI-103,MLN0128,AZD8055等ATP竞争性抑制剂仍然不可避免地导致腹泻、贫血、中性粒细胞减少和非感染性肺炎等副作用,且长期使用相同的mTOR抑制剂会导致耐药性的产生,其临床应用严重受限。因此,仍然需要开发结构类型新颖的ATP竞争性mTOR抑制剂,丰富mTOR抑制剂结构类型,为基于mTOR抑制剂的创新药物研究提供理论参考,为更好适应临床应用研究提供更多可能性、可选物。
发明内容

上述实施例1-实施例22中合成的化合物结构式如表1所示:
表1
通过以下实验来说明本发明通式(I)代表的化合物所具有的有益效果和应用。
体外mTOR激酶抑制测试:
本发明化合物抑制mTOR激酶活性,由此抑制细胞信号通路的转导,从而影响细胞周期和细胞增殖。此类化合物对mTOR激酶的抑制作用通过下述Lance Ultra荧光试验方法评价。
检测原理:Lance Ultra荧光试验是一种均质的非放射性的检测方法,它是通过检测激酶反应后体系中ATP的含量来定量测定纯化激酶的活性。ATP含量的测定是通过由Mg2+、ATP和氧催化萤火虫荧光素(beetle luciferin)发生氧化后产生的光强度来定量的。在反应体系中加入一定量的ATP,激酶反应需要消耗ATP,剩余的ATP可以与Kinase Glo试剂中的萤火虫荧光素酶发生反应后发光,从而可以定量检测剩余的ATP的量,间接测定反应激酶的活性。
检测方法:首先准备好1×kinase buffer,其中含有50mM HEPES,PH 7.5,1mMEGTA,0.01%Tween-20;用100%DMSO对化合物溶解并进行梯度稀释,转移10nL稀释后的化合物到检测板中,同时配制不含化合物的Control组和不含激酶的空白对照组。1×kinasebuffer加入mTOR配制激酶溶液,取5μL加入到检测板中涡旋混匀。另外准备1×kinasereaction buffer含有4E-BP1(Thr37/46,PE)多肽以及ATP底物,取5μL加入到孔板启动来反应,在室温条件下反应1h后,将含EDTA和Eu-anti-P-4E-BP1(Thr 37/46,PE)抗体PBS缓冲液,取10μL加入到孔板中,室温条件下孵育60min,对孔板进行读数并统计数据计算化合物对mTOR激酶的抑制率。将抑制率和相对应的浓度代入
GraphPadPrism软件进行曲线拟合,计算出IC50值。对试验结果见表2,从下表2中活性数据可知,本发明所述化合物均可有效抑制mTOR激酶,对其具有较好的抑制活性,多个化合物mTOR激酶的抑制活性(IC50)均在纳摩尔水平(1nm-999nm)。其中激酶抑制活性较高的化合物是实施例16和实施例22,其IC50值分别为48nM和49nM。因此,本发明所述化合物具有积极且可预见的抗增殖性疾病,尤其是抗肿瘤的临床应用价值,并具有很好的开发前景。
细胞活性实验:
采用Cell Counting Kit(CCK-8)法评价化合物对细胞的增殖抑制活性,通过单浓度活性初筛和多浓度测定半数抑制浓度IC50值。检测原理为CCK-8试剂中含有WST–8,它在电子载体1-甲氧基-5-甲基吩嗪硫酸二甲酯(1-Methoxy PMS)的作用下被细胞线粒体中的脱氢酶还原为具有高度水溶性的黄色甲臜产物(Formazan)。生成的甲臜物的数量与活细胞的数量成正比。具体操作如下:(1)接种细胞:用含10%胎牛血清的培养液将细胞配成单个细胞悬液,96孔板每孔接种90μL 5×104/mL的贴壁细胞和9×104/mL的悬浮细胞,在5%CO2,37℃的条件下预培养24h。(2)加入待测样品溶液:每孔加入10μL样品溶液,活性初筛每个样品设置1个浓度,设3个复孔;IC50测定8个浓度(含0浓度),每种浓度均设3个复孔;置于培养箱培养48h。实验设置空白组(Blank)、对照组(Control)和药物组(Drug)。(3)显色:贴壁细胞吸出旧培养基和药物溶液(悬浮细胞直接加入10μL CCK-8溶液原液),每孔加入稀释十倍的100μL CCK-8溶液,在37℃,5%CO2继续培养1-4h(避光操作,实时观察)。(4)检测:用酶标仪测定450nm处吸光度,记录原始数据结果。(5)应用Excel软件进行原始数据标准化处理,初筛通过每孔OD值计算细胞增殖抑制率(公式=(ODControl-ODDrug)/(ODControl-ODBlank)×100%),统计抑制率。IC50通过GraphPad Prism 8(版本8.0.2,GraphPad Software Inc)计算,实验结果用±SD表示。(6)阳性对照:盐酸阿霉素Doxorubicin(Dox)。
选取激酶抑制活性结果最好的化合物实施例16和实施例22进行细胞活性测定,首先测定化合物实施例16和实施例22对6种细胞系的增殖抑制活性,结果如表3所示,实施例16和实施例22对HCT 116、SF126、PATU8988T、5637、CAL-62和A-673六种细胞系均具有高强度的抑制活性,其抑制率均大于90%。随后测定实施例16和实施例22在六种细胞系中的IC50值,结果如表4所示,实施例16对HCT 116、SF126、PATU8988T、5637、CAL-62和A-673六种细胞系的IC50值分别为2.34μM、1.84μM、2.70μM、1.74μM、1.40μM和8.06μM。实施例22对HCT 116、SF126、PATU8988T、5637、CAL-62和A-673六种细胞系的IC50值分别为3.32μM、2.56μM、1.96μM、4.86μM、1.37μM和9.11μM。表明实施例16和实施例22对六种细胞系均具有较好的抑制活性。以上结果均表明,本研究中的新型选择性mTOR抑制剂可用于抗肿瘤研究。
