Description
技术领域
本发明涉及一类2-苯氧基嘧啶衍生物、其盐及药用前体,这类化合物具有抑制蛋白激酶及其变型的活性的作用,可用于治疗和预防增生性疾病如癌症及炎症类疾病,同时也可用于治疗和预防神经衰退性疾病如老年性痴呆症、心血管疾病、病毒感染和霉菌感染等。
背景技术
蛋白激酶是一类在蛋白质中的酪氨酸、丝氨酸和苏氨酸的羟基上磷酸化的酶。这种简单的生物化学反应涉及到细胞的各种活动,包括生长、分裂和增生。从某种意义上来讲,蛋白激酶的活性影响到细胞周期活动中的每一个环节。同时,不正常的蛋白激酶活性与各种类型的疾病(从常见的牛皮癣到致命的脑膜癌)都具有密切的联系。
蛋白激酶通常被分成酪氨酸蛋白激酶和丝氨酸/苏氨酸蛋白激酶两大类。
在蛋白激酶中,人们普遍认为酪氨酸蛋白激酶在许多细胞功能中起着非常重要的作用,特别是参与细胞信号的传递。虽然详细和精确的作用机制还不明朗,但是大量的研究结果证明酪氨酸蛋白激酶在细胞的增生、癌变和分裂过程中扮演着不可缺少的重要角色。
酪氨酸蛋白激酶又分为受体类和非受体类两大类别。受体类酪氨酸蛋白激酶通常由细胞外、贯穿细胞膜和细胞内三部分组成,而非受体类酪氨酸蛋白激酶则完全在细胞内。
受体类酪氨酸蛋白激酶含具有不同生物活性的大量且各异的贯穿细胞膜的受体。至今,根据受体部分的特征,已有约20个家族的受体类酪氨酸蛋白激酶被发现和鉴别。其中,HER亚族包括EGFR、HER2、HER3和HER4,与这一亚族的受体结合的配基包括表皮生长因子、TGF-β、细膜核模质、HB-EGF等。另一亚族是与胰岛素受体相关的酪氨酸蛋白激酶,包括INS-R、IGF-IR和IR-R。PDGF亚族则由PDGFRα、PDGFRβ、CSFIR、C-kit和FLK-II组成。还有一类FLK亚族,它包括KDR、FLK-1、FLK-4和Flt-1。由于结构和功能上的相似性,人们通常将PDGF和FLK两亚族归划在一起。有关受体类酪氨酸蛋白激酶的详细阐述,可参阅Madhani,2001,Cell;106(1):9-11。
非受体类酪氨酸蛋白激酶也具有多种亚族,像Abl、Src、Frk、Btk、Csk、ZAP70、FES/FPS、Fak、Jak、Ark和LIMK。每个亚族还可进一步分成不同的亚亚族。例如,Src是最大的亚族之一,它包括Src、Yes、Fyn、Lyn、Lck、Blk、Hck、Fgr和Yrk。该亚族被广泛认为与肿瘤形成密切相关。有关非受体类酪氨酸蛋白激酶的详细阐述,可参阅Adjei,2001,Curr Pharm Des;7(16):1581-1594。
不论是受体类还是非受体类,这些酪氨酸蛋白激酶经参与细胞的信息传递过程从而与癌症、神经功能衰退、牛皮癣和免疫功能异常等多种疾病相关。
酪氨酸蛋白激酶如Abl的活性增强与血液中骨髓干细胞类疾病如慢性骨髓细胞型白血病直接相关。
酪氨酸蛋白激酶如c-erB-2、c-Src、EGF-R、PDGF-R和ZAP70等的活性异常与人体内恶性肿瘤的形成有着密切的联系。例如,EGF-R活性增强导致头颈部癌症,而c-erB-2的高活性与乳腺癌、卵巢癌、胰腺癌、非小细胞肺癌和结肠癌有关,等等。因此,酪氨酸蛋白激酶的抑制剂可用于治疗上述的肿瘤疾病。
此外,体内酪氨酸蛋白激酶活性的异常也与其它一系列疾病有关,如牛皮癣(Dvir et al,1991,J Cell Biol;113:857-865)、纤维变性、动脉粥样硬化和心瓣变窄(Buchdanger et al,1992,Proc Natl Acad Sci USA;92:2258-2262)、自主免疫疾病、过敏、哮喘和器官移植时的排斥反应(Klausneret al,1991,Cell;64:875-878)、炎症(Berkois,1992,Blood;79(9):2246-2254)、血栓形成(Salari et al,1990,FEBS Lett;263(1):104-108)及神经系统疾病(Ohmichi et al,1992,Biochemistry;31:4034-4039)。
参与调节和减缓上述疾病状态的蛋白激酶抑制剂代表着治疗这些疾病的最新方法和趋势。目前已有许多治疗用途的蛋白激酶抑制剂的例子,以下只是其中的一些例子。(1)抑制Src、Raf和CDK用于治疗癌症(Martin,2001,Nature Rev Mol Cell Biol;2(6):467-475;Rowinsky et al,1999,J ClinOncol;17(11):3631-3652;Malumbres et al,2000,Biol Chem 381(9-10):827-838);(2)抑制CDK-2或RDGF-R用于治疗心瓣变窄(Buchdanger et al,1995,Clin Cancer Res;1(8):813-821);(3)抑制CDK-5和GSK-3用于治疗老年性痴呆症(Aplin et al,1996,J Neurochem;67(2):699-707);(4)抑制c-Src用于治疗骨质疏松症(Schmidt et al,1996,Proc Natl Acad Sci USA;93(7):3068-3073);(5)抑制GSK-3用于治疗II型糖尿病(Frame et al,2001,Mol Cell;7(6):1321-1327);(6)抑制P38用于治疗炎症(Wang et al,2000,J Immunol;166(11):6877-6884);(7)抑制VEGFR-1-3和TIE-1,2用于治疗血管再生性疾病(Hattori et al,2001,J Exp Med;193(9):1005-1014);(8)抑制uL97用于治疗病毒感染(Mendez et al,1999,Transplantation;67(5):755-757);(9)抑制CSF-1R用于治疗骨质性疾病(Hajiwaro et al,2001,Int J Hematol;73(1):100-107);(10)抑制Lck用于治疗自主免疫性疾病(Kanner et al,1995,J Immunol;154(6):2996-3005)和(11)抑制Abl用于治疗慢性骨髓细胞型白血病(Zimmermann et al,1997,Bioorg Med Chem Lett;7(2):187-192),然而同时带来意外的耐药性(Gorre et al,2001,Science;293(5531):876-880)。
美国专利5,302,739、美国专利4,770,691、美国专利4,427,437和Jojima等人(Jojima et al,1966,Agr Biol Chem;30(9):896-905)公开了一系列具有除杂草作用的2-苯氧基嘧啶类化合物。最近,Boehm等人(Boehm et al,2001,Bioorg Med Chem Lett;11(21):1123-1126)也发表了一类具有抑制P38α活性的苯氧基嘧啶衍生物。但是,这些公开化合物的主要化学结构特征以及它们的作用和用途与本发明无关。
本发明所涉及的2-苯氧基嘧啶衍生物是具有选择性的酪氨酸蛋白激酶的有效抑制剂,它们的主要作用是通过抑制酪氨酸蛋白激酶的活性而发挥,从而选择性地消除或减少特定的疾病组织。这类化合物所抑制的主要酪氨酸蛋白激酶有Abl、P38β、PDGF-R、C-kit等。当然,也不能排除这类化合物抑制其它与疾病相关的蛋白激酶的可能性。
