Description
本申请为分案申请,原申请的发明名称为“含4-酰胺苯氧基的2-氨基嘧啶杂环类化合物的制备及应用”,申请号为202010568748.7,申请日为2020.06.20。
技术领域
本发明属于化药合成领域,具体涉及一种2-氨基嘧啶杂环类化合物及其应用。
背景技术
癌症,即恶性肿瘤,能够使正常细胞的增殖和分化失去控制,进行异常分裂,并且肿瘤具有浸润性和转移性等多种生物学上的病理特征,是一种严重危害人类健康的疾病。
研究发现,EGFR与肿瘤细胞的一系列生命活动如增殖、侵袭、血管生成、肿瘤转移及凋亡的抑制息息相关。EGFR家族成员具有举足轻重的地位,因而己经成为了治疗癌症的首要也是主要的靶标,尤其是针对NSCLC的治疗。通过抑制EGFR酪氨酸的激酶活性,阻断其信号通路传导,可有效抑制肿瘤的生长。
发明内容
为了研制出新型高效的抗肿瘤药物,发明人对氨基杂环嘧啶类化合物进行了广泛研究,在保留氨基嘧啶、迈克尔受体等活性基团的基础上,维持第三代EGFR抑制剂化合物的U型结构支架,在嘧啶环和丙烯酰胺侧链上引入了小分子烷基侧链和卤素等活性基团以调节化合物的反应性,通过分子对接结果改变母核结构,设计并合成了一系列结构新颖的含4-酰胺苯氧基的2-氨基嘧啶杂环类化合物,其结构如下述通式I或Ⅱ所示:
R1选自五元或六元的杂环、芳环或芳杂环,含有1-3个选自氢、卤素、三氟甲基、氰基、甲氧基或C1~C4烷基的取代基;

R4、R5相同或不同,分别独立地选自C1~C6烷基、C3~C6环烷基、羟乙基、巯基乙基;或者,R4和R5与和它们所连接的氮原子一起形成5~10元饱和杂环基,所述饱和杂环基除了与R4和R5连接的氮原子外,任选含有1~3个选自O、N和S的杂原子;n为0~3。
该化合物能够用于制备治疗和/或预防前列腺癌、肺癌和宫颈癌的药物中。
优选地,R1选自:
其中R6选自氢、卤素、三氟甲基、氰基、硝基、羟基、氨基、巯基、羧基、三氟甲氧基、甲基、乙基、丙基、丁基、环丙烷、乙烯、丙烯、乙炔、丙炔、甲氧基、乙氧基、丙氧基、异丙氧基、丁氧基或叠氮基;
R7选自卤素、羟基、三氟甲基、三氟甲氧基、氨基、叠氮基、氰基、巯基、C1~C4烷基、C3~C6环烷基、C1~C4烯基、C1~C4炔基、C1~C4烷氧基。
更为优选地,R1选自苯环或吡啶,所述的苯环或吡啶含有1个甲氧基的取代基。
优选地,-R2(CH)2R3选自:
更为优选地,R2选自H或F。R3选自甲基、乙基、异丙基、氢或丙基。

本发明产物的药理研究
体外细胞毒活性
对按照本发明的通式Ⅰ和Ⅱ的含嘧啶及吡啶类喹啉衍生物进行了体外抑制肺癌细胞A549、乳腺癌细胞MCF-7、宫颈癌细胞Hela及人正常细胞LO2活性筛选,对照品为奥莫替尼。
(1)细胞复苏并传代2-3次稳定后,用胰蛋白酶溶液(0.25%)使其从培养瓶底部消化下来。将细胞消化液倒入离心管中后,之后加入培养液以终止消化。将离心管在800r/min下离心10min,弃去上清液后加入5mL培养液,吹打混匀细胞,吸取10μL细胞混悬液加入细胞计数板中计数,调整细胞浓度为104个/孔。96孔板中除A1孔为空白孔不加细胞外,其余皆加入100μL细胞混悬液。将96孔板放入培养箱中培养24h。
(2)用50μL二甲基亚砜溶解受试样品,然后加入适量培养液,使样品溶解成2mg/mL药液,然后在24孔板中将样品稀释为20,4,0.8,0.16,0.032μg/mL。
每个浓度加入3孔,其中周围两行两列细胞长势受环境影响较大,只和为空白细胞孔使用。将96孔板放入培养箱中培养72h。
(3)将96孔板中带药培养液弃去,用磷酸缓冲溶液(PBS)将细胞冲洗两遍,在每孔中加入MTT(四氮唑)(0.5mg/mL)100μL放入培养箱中4h后,弃去MTT溶液,加入二甲基亚砜100μL。在磁力振荡器上振荡使存活细胞与MTT反应产物甲臜充分溶解,放入酶标仪中测定结果。通过Bliss法可求出药物IC50值。
化合物的抑制肺癌细胞A549、乳腺癌细胞MCF-7、宫颈癌细胞Hela及人正常细胞LO2活性结果(见表2)。
EGFR激酶活性试验
以奥莫替尼为阳性对照,利用HTRF技术,测试新合成化合物对各种癌细胞抑制作用的IC50值,并测试部分化合物对EGFR的抑制作用。
具体方法:配制所需浓度的ATP、TK Substrate-biotin(TK-底物生物素)、Kinasebuffer(激酶缓冲液)的工作液,ATP、TK Substrate-biotin、Kinase buffer按体积比例2:2:2取液混匀;用Kinase buffer稀释药物配制为所需浓度;配制EGFR酶工作液。在白色384孔板中,每孔加入6μL混匀液,2μL药物,2μL激酶,混匀,置于37℃下反应30min。然后加入5μL链激酶素标记的XL-665及5μL结合了Eu3+的穴状化合物抗体,混匀。室温放置30min后于酶标仪314nm激发,检测665、620nm波长处的荧光,计算激酶抑制率,根据吸光度用Bliss法计算出每个药物的IC50值。
抑制率(%)=(Ratio665/620对照孔-Ratio665/620给药孔)/Ratio665/620对照孔×100%。
实验数据均以平均值±标准差表示,计量资料的组间显著性检验采用单因素方差分析,两两比较采用t检验,p<0.05为有显著性差异,p<0.01为有非常显著性差异。
表2部分目标化合物体外抗肿瘤活性
表3部分目标化合物酶活性
从上述试验结果可以清楚地看出,本发明所要保护的通式Ⅰ和Ⅱ的化合物,具有良好的体外抗细胞增殖活性和抗EGFR激酶活性,所有目标化合物对人正常细胞LO2的毒性低于奥莫替尼,部分化合物对L858R/T790M双突变细胞肺癌细胞H1975的抑制活性优于奥莫替尼。从上表的数据可以看出,相对于抗EGFR野生型激酶活性,实例化合物对EGFR双突变激酶具有一定的选择性,这也可证明实例化合物靶向性好,选择性高,如实施例1和6。由此可得出结论,本发明中通式Ⅰ和Ⅱ的化合物可能是潜在的EGFR抑制剂。
