Description

吡啶并嘧啶类化合物在制备治疗鼻咽癌药物中的应用
本申请主张如下优先权:
CN201910049704.0,申请日2019年1月18日。
技术领域
本发明涉及一类吡啶并嘧啶类化合物在制备治疗鼻咽癌药物中的应用。具体涉及式(I)所示化合物或其药学上可接受的盐在制备治疗鼻咽癌药物中的应用。
技术背景
肿瘤,特别是恶性肿瘤是目前危害人类健康的最严重一大类疾病之一,随着科技的进步和人们对肿瘤治疗研究的越来越深入,在肿瘤的发生,发展机制上和肿瘤的治疗方面取得了飞速的进展。很多新的机制和生物标着物被发现。本发明涉及到一条对肿瘤的增殖、侵润转移和抗凋亡起关键作用的信号通路,即磷脂酰肌醇3激酶(PI3K)-AKT-哺乳动物雷帕霉素蛋白酶mTOR信号通路。
PI3K的活化很大程度上参与到靠近其质膜内侧的底物。多种生长因子和信号传导复合物,包括成纤维细胞生长因子(FGF)、血管内皮生长因子(VEGF)、人生长因子(HGF)、血管位蛋白I(Ang1)和胰岛素都能启始PI3K的激活过程。这些因子激活受体酪氨酸激酶(RTK),从而引起自磷酸化。PI3K激活的结果是在质膜上产生第二信使PIP3,PIP3与细胞内含有PH结构域的信号蛋白AKT和PDK1(phosphoinositide dependent kinase-1)结合,促使PDK1磷酸化AKT蛋白的Ser308导致AKT活化。其它PDK1的底物还包括PKC(蛋白激酶C)、S6K(p70S6)和SGK(serum/glucocorticoid regulated kinases)。AKT,亦称为蛋白激酶B(PKB),是PI3K下游主要的效应物。活化的AKT通过磷酸化多种酶、激酶和转录因子等下游因子,进而调节细胞的功能。AKT通过下游多种途径对靶蛋白进行磷酸化而发挥抗凋亡作用。PTEN(phosphatase and tensin homology deleted on chromosome 10),是一种抑癌基因,在广泛的人类肿瘤中发生基因突变或缺失。PTEN是一个PIP3-磷酸酶,与PI3K的功能相反,它可以通过去磷酸化将PIP3转变为PIP2。PTEN可减少AKT的活化而阻止所有由AKT调控的下游信号传导事件。mTOR作为AKT下游底物,进化上相对保守,可整合营养、能量及生长因子的多种信号,参与基因的转录、蛋白质翻译、核糖体合成和细胞凋亡等生物过程,在细胞生长中发挥极为重要的作用。其有两种高度同源的复合物,Tor与KOG01结合形成mTORC1,mTOR与AVO1/AVO2/AVO3/和LST8形成对雷帕霉素不敏感的mTORC2.mTOR通过磷酸化下游靶蛋白S40S核糖体S6蛋白激酶,比如S6K1和4EBP1来调节下游蛋白翻译。mTOR与eIF3结合,磷酸化S6K1,使S6K1从eIF3上释放而被活化,进一步磷酸化细胞底物,如p70S6促进蛋白质翻译及表达。4EBP1与真核转录启动因子4E结合并抑制其活性,当mtor磷酸化4E-BP1后,使其活化与eif-4e分离,实现真核细胞转录。mTORC2能磷酸化AKT,从而上调其激酶活性。
由上可见,PI3K/AKT/mTOR信号通路上游出现任何的突变或过度表达,都会导致下游一系列级联反应,最终导致肿瘤的发生,发展和转移。而mTOR处于信号通路的枢纽,对mTORC1和mTORC2的抑制能很好的阻断信号的传递,从而达到控制肿瘤的发展。
研究发现,此信号通路在多种实体瘤,如鼻咽癌、乳腺癌、前列腺癌、肺癌、结肠癌、胰腺癌、肝癌、胃癌、结直肠癌、肾癌、甲状腺癌、脑膜炎癌和急慢性淋巴细胞白血病,梅克尔细胞瘤等。并且与 治疗耐受和不良预后紧密相关。由此可见,通过开发细分子化合物实现对PI3K/AKT/MTOR的信号通路的抑制,具有良好的开发前景。
本发明旨在发现一种双mTOR小分子化合物靶向药物,此类化合物具有良好的活性,并表现出了优异的效果和作用。
US20170281637公开化合物AZD2014,属于mTORC1&mTORC2激酶抑制剂,其结构式如下所示:

相关定义
除非另有说明,本文所用的下列术语和短语旨在具有下列含义。一个特定的术语或短语在没有特别定义的情况下不应该被认为是不确定的或不清楚的,而应该按照普通的含义去理解。当本文中出现商品名时,意在指代其对应的商品或其活性成分。这里所采用的术语“药学上可接受的”,是针对那些化合物、材料、组合物和/或剂型而言,它们在可靠的医学判断的范围之内,适用于与人类和动物的组织接触使用,而没有过多的毒性、刺激性、过敏性反应或其它问题或并发症,与合理的利益/风险比相称。

本发明的化合物可以存在特定的。除非另有说明,术语“互变异构体”或“互变异构体形式”是指在室温下,不同官能团异构体处于动态平衡,并能很快的相互转化。若互变异构体是可能的(如在溶液中),则可以达到互变异构体的化学平衡。例如,质子互变异构体(proton tautomer)(也称质子转移互变异构体(prototropic tautomer))包括通过质子迁移来进行的互相转化,如酮-烯醇异构化和亚胺-烯胺异构化。价键异构体(valence tautomer)包括一些成键电子的重组来进行的相互转化。其中酮-烯醇互变异构化的具体实例是戊烷-2,4-二酮与4-羟基戊-3-烯-2-酮两个互变异构体之间的互变。
可以通过的手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D和L异构体。如果想得到本发明某化合物的一种对映体,可以通过不对称合成或者具有手性助剂的衍生作用来 制备,其中将所得非对映体混合物分离,并且辅助基团裂开以提供纯的所需对映异构体。或者,当分子中含有碱性官能团(如氨基)或酸性官能团(如羧基)时,与适当的光学活性的酸或碱形成非对映异构体的盐,然后通过本领域所公知的常规方法进行非对映异构体拆分,然后回收得到纯的对映体。此外,对映异构体和非对映异构体的分离通常是通过使用色谱法完成的,所述色谱法采用手性固定相,并任选地与化学衍生法相结合(例如由胺生成氨基甲酸盐)。本发明的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位素。例如,可用放射性同位素标记化合物,比如氚( 3H),碘-125( 125I)或C-14( 14C)。又例如,可用重氢取代氢形成氘代药物,氘与碳构成的键比普通氢与碳构成的键更坚固,相比于未氘化药物,氘代药物有降低毒副作用、增加药物稳定性、增强疗效、延长药物生物半衰期等优势。本发明的化合物的所有同位素组成的变换,无论放射性与否,都包括在本发明的范围之内。术语“药学上可接受的载体”是指能够递送本发明有效量活性物质、不干扰活性物质的生物活性并且对宿主或者患者无毒副作用的任何制剂或载体介质代表性的载体包括水、油、蔬菜和矿物质、膏基、洗剂基质、软膏基质等。这些基质包括悬浮剂、增粘剂、透皮促进剂等。它们的制剂为化妆品领域或局部药物领域的技术人员所周知。
“任选”或“任选地”指的是随后描述的事件或状况可能但不是必需出现的,并且该描述包括其中所述事件或状况发生的情况以及所述事件或状况不发生的情况。
术语“被取代的”是指特定原子上的任意一个或多个氢原子被取代基取代,可以包括重氢和氢的变体,只要特定原子的价态是正常的并且取代后的化合物是稳定的。当取代基为氧(即=O)时,意味着两个氢原子被取代。氧取代不会发生在芳香基上。术语“任选被取代的”是指可以被取代,也可以不被取代,除非另有规定,取代基的种类和数目在化学上可以实现的基础上可以是任意的。
当任何变量(例如R)在化合物的组成或结构中出现一次以上时,其在每一种情况下的定义都是独立的。因此,例如,如果一个基团被0-2个R所取代,则所述基团可以任选地至多被两个R所取代,并且每种情况下的R都有独立的选项。此外,取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
当一个连接基团的数量为0时,比如-(CRR) 0-,表示该连接基团为单键。
当其中一个变量选自单键时,表示其连接的两个基团直接相连,比如A-L-Z中L代表单键时表示该结构实际上是A-Z。
除非另有规定,术语“烷基”用于表示直链或支链的饱和烃基,可以是单取代(如-CH 2F)或多取代的(如-CF 3),可以是一价(如甲基)、二价(如亚甲基)或者多价(如次甲基)。烷基的例子包括甲基(Me),乙基(Et),丙基(如,n-丙基和异丙基),丁基(如,n-丁基,异丁基,s-丁基,t-丁基),戊基(如,n-戊基,异戊基,新戊基)等。
除非另有规定,术语“C 1-3烷基”用于表示直链或支链的由1至3个碳原子组成的饱和碳氢基团。所述C 1-3烷基包括C 1-2和C 2-3烷基等;其可以是一价(如甲基)、二价(如亚甲基)或者多价(如次甲基)。C 1-3烷基的实例包括但不限于甲基(Me)、乙基(Et)、丙基(包括n-丙基和异丙基)等。
除非另有规定,术语“卤代素”或“卤素”本身或作为另一取代基的一部分表示氟、氯、溴或碘原子。此外,术语“卤代烷基”意在包括单卤代烷基和多卤代烷基。例如,术语“卤代(C 1-C 4)烷基”意在包括但 不仅限于三氟甲基、2,2,2-三氟乙基、4-氯丁基和3-溴丙基等等。除非另有规定,卤代烷基的实例包括但不仅限于:三氟甲基、三氯甲基、五氟乙基,和五氯乙基。

4.5统计分析
统计分析,包括每个组的每个时间点的肿瘤体积的平均值和标准误(SEM)(具体数据见表5-1)。治疗组在试验结束时给药后第28天表现出最好的治疗效果,因此基于此数据进行统计学分析评估组间差异。两组间比较用T-test进行分析,三组或多组间比较用one-way ANOVA进行分析,经检验,F值有显著性差异,应用Games-Howell法进行检验。用SPSS 17.0进行所有数据分析。p<0.05认为有显著性差异。
