Abstract

本发明公开了一种取代的吡啶并嘧啶化合物及其制备方法和应用。所示取代的吡啶并嘧啶化合物的结构通式如式I所示,其中Ar为取代的吡啶基。本发明的研究发现这类化合物是一种多激酶抑制剂,能同时抑制多种存在于细胞内和细胞表面的激酶,包括PI3-K和/或mTOR激酶。由此,这类化合物及其药学上可接受的盐可用于制备治疗和/或预防PI3-K和/或mTOR激酶引起的疾病(癌症)的药物。

Description

取代的吡啶并嘧啶化合物及其制备方法和应用 技术领域
本发明涉及药物化学领域,具体涉及一类取代的吡啶并嘧啶化合物,以及它们的制备方法和其作为PI3-K和/或mTOR激酶抑制剂的用途。
背景技术
抗肿瘤药物的研究与开发是当今生命科学中极富挑战性且意义重大的领域。近年来,随着分子生物学的飞速发展以及人们对癌症发生、发展、作用机制的进一步认识,恶性肿瘤细胞内的信号转导、细胞周期的调控、细胞凋亡的诱导、血管生成以及细胞与胞外基质的相互作用等各种基本过程正在被逐步阐明。因此寻找和发现选择性作用于特定靶点的高效、低毒、特异性强的新型抗肿瘤药物已成为当前药物研究开发的重要领域之一。由此产生了一个新的抗癌药物领域-分子靶向药物。
分子靶向药物是指针对细胞癌变过程的受体或转导过程中关键的酶,从分子水平抑制肿瘤生长的治疗模式。以肿瘤细胞的特征分子为靶点,在发挥抗肿瘤作用的同时,减少了对正常细胞的毒副作用。
磷酸肌醇3-激酶(PI3-K)催化磷脂酰肌醇(PI)第二信使PI(3)P、PI(3,4)P2及PI(3,4,5)P3(PIP3)的合成。在适当的细胞环境下,这三种脂质控制多种包括细胞生长、存活、分化及趋化性的生理学过程。癌症中的主要PI3-激酶同功异型物为由催化性(p110α)亚单元及转接子(p85)亚单元组成的I类PI3-Kα。PI3-K/Akt/PTEN通路的数种组分涉及肿瘤形成,在包括细胞周期调节、增生、存活、细胞凋亡及运动的许多细胞过程的调控中发挥重要作用,且为诸如癌症、糖尿病及免疫性炎症等疾病的分子机制的重要组分。
mTOR属于PI3K超家族中的一个丝氨酸-苏氨酸蛋白激酶组,也 被称为IV型PI3-K。mTOR负责监测营养可获得性,细胞能量水平,含氧量和有丝分裂信号,在细胞的生长和增殖中起着至关重要的调节作用。mTOR存在mTORC1和mTORC2两种复合物。
AKT,又称为蛋白激酶B(protein kinase B,PKB),是原癌基因c-akt编码表达的一种丝氨酸-苏氨酸蛋白激酶,作为PI3K/AKT信号转导通路的核心,其持续活化与肿瘤的发生发展密切相关。AKT可以通过磷酸化PRAS40和肿瘤抑制蛋白TSC2,减轻二者对mTORC1的抑制作用,从而激活mTOR,提高mRNA翻译的效率,从而增加一系列与细胞生长和分化相关蛋白的表达,加快了肿瘤的发生。mTORC2复合物具有PDK2活性,可以磷酸化并激活AKT。
因此,PI3-Kα以及mTOR激酶是开发癌症药物的具有吸引力和前景的靶标,此类药剂将抑制癌细胞增生,且避免了细胞毒制剂对机体的损伤,及癌细胞对细胞毒制剂的耐受。人们需要新颖的PI3-Kα抑制剂以及mTOR激酶抑制剂,以作为癌症治疗药物应用于癌症治疗领域。
