4-苯胺喹唑啉衍生物的制药用途
技术领域
本发明涉及 4-苯胺喹唑啉衍生物的制药用途。 具体的说, 本发明涉及 4-苯 胺喹唑啉衍生物在制备抗肿瘤药物中的应用。 背景技术
癌症被认为是细胞内信号传导系统或信号传导机制的疾病。细胞接受许多 来自细胞外的指令, 指导细胞是否增殖, 信号传导系统的目的是接受细胞表面 的这些或其它信号, 将其导入细胞内, 然后将这些信号传递到细胞核、 细胞骨 架, 影响基因的转录和蛋白质的合成。
细胞表面存在大量的受体, 生长因子与这些受体的相互作用是细胞生长正 常调节的必需事件。 然而, 在某些条件下, 由于这些受体或者突变或者过量表 达, 这些受体可变为异常,其结果是细胞繁殖不受控制,最终导致肿瘤的生长。
表皮生长因子受体(EGFR)被确定为在细胞生长和繁殖过程中至关重要的 驱动因素, 在常见的肿瘤, 如非小细胞肺癌中, 表皮生长因子受体大量表达, 远远超出 正常范 围 。 表皮生长 因子受体家族 由 EGFR (Erb-Bl) 、 Erb-B2 (HER-2/neu) , Erb-B3和 Erb-B4组成。 表皮生长因子受体与大部分癌症 的疾病进程有关, 特别是结肠癌和乳腺癌。 该受体的过度表达和突变已被明确 证实是预后不好的乳腺癌的主要危险因素。 此外, 已证实该受体家族的所有四 个成员均可与该家族的其它成员聚合为异源二聚体, 形成信号传导复合物, 如 果该家族中有一个以上的成员在恶性肿瘤中过度表达, 便可导致协同的信号传 导作用。
EGFR属于蛋白酪氨酸激酶(PTK)家族, 蛋白酪氨酸激酶是一类将磷酸基团 从 ATP催化转移到位于蛋白质底物的酪氨酸残基的酶。 蛋白酪氨酸激酶在正常 细胞生长中起作用。 EGFR的过度表达, 导致受体在缺乏配体的条件下被激活, 使某些蛋白发生磷酸化, 产生了细胞分裂的信号。 因此, EGFR通过自身酪氨酸 激酶的作用, 导致了弱信号的过度放大, 引起了细胞的过量增值。
由于异常的受体激酶在癌发病机理中所起作用的重要性, 因此最近的许多 研究都涉及作为潜在抗癌治疗药物的特异的 PTK 抑制剂的研制。
欧洲专利申请 520722 A1 公开了某些 4-苯胺基间二氮杂萘具有 PTK抑制剂 活性。
欧洲专利申请 566226 Al公开了在位置 5-8含有许多取代基的 4-苯胺基间二 氮杂萘具有 PTK抑制剂活性。
从欧洲专利申请 635498 A1 得知, 在位置 6含有许多取代基、 在位置 7必须 有一个卤素的某些 4-苯胺基间二氮杂萘也具有 PTK抑制剂活性。
W096/30347涉及一些 4- (取代苯氨基)喹唑啉衍生物、其前药和其药学上可 接受的盐, 用于治疗过度增生疾病。
W097/38983提供了作为酪氨酸激酶不可逆抑制剂的化合物。
W000/06555也涉及某些取代的喹唑啉的衍生物具有 PTK抑制剂活性。
W099/35146公开了作为蛋白酪氨酸激酶抑制剂的二环杂芳族化合物。 然而, 目前仍缺乏令人满意的肿瘤治疗药物, 因此本领域仍需要开发对受 体激酶有抑制活性的肿瘤治疗药物。 发明概述
