Definitions

  • the present invention relates to a novel class of indanylamide compounds, or a pharmaceutically acceptable salt of such a compound, Their preparation methods, and pharmaceutical compositions containing them, and their preparation for preventing or treating diseases associated with abnormal protein kinase activity, particularly associated with abnormal activity of Abl, Bcr-Abl, c-Kit and PDGFR protein kinases, The use of drugs for diseases, and methods for preventing or treating diseases associated with abnormalities in protein kinase activity, particularly diseases associated with abnormal activities of Abl, Bcr-Abl, c-Kit and PDGFR protein kinases. Background technique
  • Protein kinases are enzymes that transfer the phosphoric acid of adenosine triphosphate to specific serine, threonine or tyrosine residues on the protein shield. Phosphorylation of the protein shield leads to activation of the signaling pathway and plays a key role in a variety of biological processes, including cell growth, metabolism, differentiation and death. Abnormal signals caused by abnormal or inappropriate protein kinase activity are known to be associated with many diseases, including cancer, inflammation, autoimmune diseases, metabolic diseases, infections, central nervous system diseases, and cardiovascular diseases. Therefore, protein kinases are attractive targets for drug development (Cohen, Nat. Rev. Drug Discovery 2002, 1, 309).
  • the abl and bcr genes located on chromosomes 9 and 22, respectively, are normal genes.
  • the two genes translocate to each other to produce two fusion genes: the bcr-abl gene located on the 22q-chromosome and the abl-bcr gene located on the 9q+ chromosome.
  • the bcr-abl gene is a Philadelphia chromosome that expresses a 210 kD protein shield (p210Bcr-Abl).
  • the Abl portion of the Bcr-Abl protein shield contains Abl's tyrosine kinase, which is tightly regulated in the prototype c-Abl, but is continuously activated in the Bcr-Abl fusion protein shield, resulting in uncontrolled cell growth .
  • Bcr-Abl is present in 95% of patients with chronic myeloid leukemia (CML) and 10-25% of patients with acute lymphoblastic leukemia (ALL).
  • Imatinib marketed as Gleevec, is an inhibitor of Bcr-Abl tyrosine kinase and has been clinically proven to treat chronic myelogenous leukemia (CML).
  • An effective formulation Druker et al. N. Engl. J. Med. 2006, 355, 2408).
  • some CML patients relapse in the late or explosive phase of the crisis due to drug resistance.
  • the molecular basis of drug resistance is the appearance of a variant of Imatinib resistance in the kinase structural region of Bcr-Abl. So far, more than 22 mutants have been traced, the most common are M244V, G250E, Q252H, Y253F, Y253H, E255K, E255V, F311L, T351I, F317L, M351T, F359V, V379I, L387M, H396P , and H396R et al. (Nardi, et al. Curr. Opin. Hematol. 2004, 11, 35).
  • c-Kit (CD117, a cytokine receptor) is a growth factor receptor with tyrosine kinase activity and is produced by the protooncogene c-kit. Once combined with the Thymocyte Factor (SCF), it is activated. C-kit mutations cause continuous activation of c-Kit tyrosine kinase function, resulting in ligand-independent tyrosine kinase activity, c-Kit autophosphorylation, and uncontrolled cell proliferation. c-Kit is overexpressed and mutated in most gastrointestinal tract tumors (GIST). The gastrointestinal tract tumor is a group of intersegmental tumors produced by the precursors of the cells of the digestive tract tissue.
  • c-Kit is also over-expressed and mutated in a variety of other human cancers, including mast cell tumors, neuroblastoma, germ cell tumors, melanoma, small cell lung cancer, breast cancer, ovarian cancer, and acute myeloid leukemia (see Edling et al. Int. J. Biochem. Cell Biol. 2007, 39, 1995; Lennartsson et al. Curr. Cancer Drug Targets, 2006, 6, 65).
  • SCF/c-Kit is also associated with autoimmune and inflammatory diseases.
  • SCF is expressed in the airways by a variety of structural and inflammatory cells. Binding of SCF to c-Kit leads to activation of multiple pathways, including phosphatidylinositol-3 (PI3) kinase, phospholipase C (PLC), Src protein kinase, Janus kinase (JAK)/signal transducer and activator of transcription (STAT) and protein kinase pathways of mitogen-activated protein (MAP).
  • PI3 phosphatidylinositol-3
  • PLC phospholipase C
  • COK Janus kinase
  • STAT protein kinase pathways of mitogen-activated protein
  • SCF/c-Kit is a potential therapeutic target that controls the number of mast cells and eosinophils and controls the activation of autoimmune and inflammatory diseases.
  • diseases include skin inflammation, rheumatoid arthritis, allergic rhinitis, asthma, ankylosing spondylitis, psoriasis, and Crohn's disease (see Reber et al. Eur. J. Pharmacol. 2006, 533, 327; Paniagua et al Nat. Clin. Prac. Rheum. 2007, 3, 190).
  • Platelet-derived growth factor receptors such as PDGFR- ⁇ and PDGFR- ⁇ , are transmembrane tyrosine kinase receptors. Its ligand is formed by two A chains (PDGF-A), or two B chain formations (PDGF-B), or one A chain and one B chain heterodimer formation (PDGF-AB). Once bound to the ligand, the platelet-derived growth factor receptor forms a dimerization and its tyrosine kinase is activated, signaling to the downstream region.
  • PDGF-A two A chains
  • PDGF-B two B chain formations
  • PDGF-AB A chain and one B chain heterodimer formation
  • PDGFR-alpha signaling Studies in PDGFs and PDGFRs in animals have revealed the role of PDGFR-alpha signaling in the development of gastrulation and cranial and cardiac neural crest, gonads, lungs, intestines, skin, central nervous system and bone. Similarly, the role of PDGFR- ⁇ signaling in vascular formation and early hematopoietic function has also been revealed. Platelet-derived growth factor signaling is implicated in a range of diseases. The autocrine activation of the growth factor signaling pathway is associated with certain brain gelatinous tumors, myeloproliferative diseases, tumors, multiple myeloma and sarcomas including dermatofibrosarcoma.
  • Paracrine growth factor signaling is common in epithelial cancer, where it triggers basal inhalation and may be involved in epithelial-to-cell transition, affecting tumor growth, angiogenesis, invasion, and metastasis.
  • Platelet-derived growth factor drives vascular disease response to vascular disease, such as atherosclerosis, arterial stenosis, pulmonary hypertension, and retinal diseases, as well as liver fibrosis, including interpulmonary fibrosis, cirrhosis, scleroderma, Glomerular sclerosis, and myocardial fibrosis (see Andrae Et al. Gene Dev. 2008, 22, 1276). Therefore, inhibition of PDGFR can prevent and treat the above diseases.
  • inhibition of PDGFR can also treat various autoimmune diseases and inflammatory diseases including diabetes, especially type I diabetes, rheumatoid arthritis, psoriasis, and Crohn's disease (Paniagua et al. Nat Clin. Prac. Rheum. 2007, 3, 190; and Louvet et al. Proc. Natl. Acad. Sci. USA, 2008, 105, 18895).

Description

二氢化茚酰胺化合物制备方法、 包含其的 药物组合物、 及其作为蛋白激酶抑制剂的应用 技术领域 本发明涉及一类新的二氢化茚酰胺化合物, 或此类化合物药学上可接受的盐, 它们的制备方法, 以及含有它们的药物组合物, 和它们在制备用于防止或治疗与蛋 白激酶活性异常相关的疾病, 特别是与 Abl, Bcr-Abl, c-Kit和 PDGFR蛋白激酶活 性异常相关的疾病的药物中应用, 以及它们用于防止或治疗与蛋白激酶活性异常相 关的疾病, 特别是与 Abl, Bcr-Abl, c-Kit和 PDGFR蛋白激酶活性异常相关的疾病 的方法。 背景技术
蛋白激酶是将三磷酸腺苷的磷酸转移到蛋白盾上特定的丝氨酸、 苏氨酸或酪 氨酸残基上的酶。 蛋白盾的磷酸化导致信号传导途径的激活, 对各种各样的生物过 程起了关键的作用, 包括细胞生长、 代谢、 分化和死亡。 由不正常或不适当的蛋白 激酶活性引起的异常信号已知与很多疾病相关, 包括癌症、 炎症、 自身免疫性疾病、 代谢性疾病、 感染、 中枢神经***疾病和心血管疾病等。 因此, 蛋白激酶是药物开 发很有吸引力的靶标 (Cohen, Nat. Rev. Drug Discovery 2002, 1, 309)。
分别位于第 9号和第 22号染色体的 abl和 bcr基因是正常的基因。 这两个基 因相互易位产生了两个融合基因: 位于 22q-染色体上的 bcr-abl基因和位于 9q+染色 体上 abl-bcr基因。 bcr-abl基因是费城染色体,它表达 210kD的蛋白盾 (p210Bcr-Abl)。 Bcr- Abl蛋白盾的 Abl部分含有 Abl的酪氨酸激酶, 它在原型的 c- Abl中是受严密 调节的, 但在 Bcr-Abl 融合蛋白盾中被连续地激活, 从而导致细胞生长的失控。 Bcr-Abl存在于 95 %慢性髓性白血病 (CML)的患者中,以及 10- 25 %急性淋巴细胞白 血病 (ALL)的患者中。伊马替尼( Imatinib ), 商品名为格列卫 (Gleevec)是一种 Bcr-Abl 酪氨酸激酶的抑制剂, 并已临床证明是一种治疗 CML ( chronic myelogenous leukemia,慢性髓细胞性白血病)的有效制剂(Druker et al. N. Engl. J. Med. 2006, 355, 2408)。 然而, 尽管持续伊马替尼(Imatinib )治疗, 一些 CML患者在晚期或***危 机阶段会复发, 原因是产生对药物的抗药性。 抗药性的分子基础是 Bcr-Abl的激酶 结构区域出现对 Imatinib抗性的变体。到目前为止,已有 22种以上的突变体 4艮道过, 最常见的是 M244V, G250E, Q252H, Y253F , Y253H, E255K, E255V, F311L, T351I, F317L, M351T, F359V, V379I, L387M, H396P, 和 H396R等 (Nardi, et al. Curr. Opin. Hematol. 2004, 11, 35)。 c-Kit ( CD117, 千细胞因子受体)是具有酪氨酸激酶活性的一种生长因子受 体, 是原癌基因 c-kit产生的。 一旦与千细胞因子 (SCF)结合, 它就被激活。 c-kit突 变引起 c-Kit酪氨酸激酶功能的连续激活,造成独立于配体的酪氨酸激酶活性, c-Kit 自身磷酸化, 以及细胞增殖失控。 c-Kit在大多数胃肠道间盾瘤 (GIST)有过度表达和 突变。 胃肠道间盾瘤是一组间盾肿瘤, 由消化道组织细胞的前体产生的。 他们主要 发生在中年和老年人。 约 70 %的肿瘤发现在胃中, 20- 30 %发现在小肠中, 小于 10 %发现在食道、 结肠、 和直肠中。 众所周知, 胃肠道间盾瘤对经典的癌症化疗不起 作用, 但可以用伊马替尼( imatinib )抑制 c-Kit而得到有效地治疗, 这表明了 c-Kit 在这些疾病的发病机制中的关键作用(Joensuu et al. N. Engl.JMed.200l , 344, 1052)。 c-Kit还在其他各种人类癌症中有过量表达和突变, 包括肥大细胞肿瘤, 神经母细胞 瘤, 生殖细胞肿瘤, 黑色素瘤, 小细胞肺癌, 乳腺癌, 卵巢癌和急性髓性白血病 (参 见 Edling et al. Int. J. Biochem. Cell Biol. 2007, 39, 1995; Lennartsson et al. Curr. Cancer Drug Targets, 2006, 6, 65)。
除了在癌症方面的作用外, SCF/c-Kit还与自体免疫性和炎症性疾病有关。 SCF 在气道由各种结构性和炎性细胞所表达。 SCF与 c-Kit的结合导致多种途径的激活, 包括磷脂酰肌醇 -3(PI3)激酶、 磷脂酶 C(PLC) 、 Src蛋白激酶、 Janus激酶 (JAK)/信 号转导和转录激活因子(STAT)和丝裂原活化蛋白(MAP)的蛋白激酶途径。 对 SCF/c-Kit途径的抑制可显著减少组胺水平, 减少肥大细胞和嗜酸性粒细胞的渗入, 减少白细胞 (IL)-4的产生和气道的过高反应性。 因此, SCF/c-Kit是一个潜在的治疗 目标, 可以控制肥大细胞和嗜酸性粒细胞的数量, 控制自体免疫性和炎症性疾病的 激活。 这些疾病包括皮肤炎症, 类风湿关节炎, 过敏性鼻炎, 哮喘, 强直性脊柱炎, 牛皮癣,和克罗恩病(参见 Reber et al. Eur. J. Pharmacol. 2006, 533, 327; Paniagua et al. Nat. Clin. Prac. Rheum. 2007, 3, 190) 。
血小板衍生生长因子受体 (PDGFR) , 如 PDGFR-α和 PDGFR-β是跨膜酪氨酸 激酶受体。 其配体由两个 A链形成 (PDGF-A) , 或两个 B链形成 (PDGF-B) , 或一个 A链和一个 B链的异形二聚物形成 (PDGF-AB)。 一旦与配体结合, 血小板衍生生长 因子受体形成二聚,其酪氨酸激酶被激活,向下游区发出信号。对 PDGFs和 PDGFRs 在动物里的研究揭示出 PDGFR-α信号在原肠胚化和头颅和心脏神经嵴, 性腺, 肺, 肠, 皮肤, 中枢神经***和骨骼的发展的作用。 同样, PDGFR-β信号在血管的形成 和早期造血功能的作用也已经揭示出来了。 血小板衍生生长因子信号与一系列疾病 有牵连。 生长因子信号通路的自分泌激活与某些脑胶盾瘤, 骨髓增生性疾病, 肿瘤, 多发性骨髓瘤和肉瘤包括隆突性皮肤纤维肉瘤有关。 旁分泌生长因子信号常见于上 皮癌, 在那里它引发基盾的吸入, 并且可能参与上皮细胞间盾转型, 从而影响肿瘤 的生长、 血管生成、 侵袭和转移。 血小板衍生生长因子驱动血管疾病的器盾病变反 应, 如动脉粥样硬化、 动脉狭窄、 肺动脉高压、 和视网膜疾病、 以及肝纤维化的疾 病, 包括肺间盾纤维化、肝硬化、硬皮病、 肾小球硬化、 和心肌纤维化 (参见 Andrae et al. Gene Dev. 2008, 22, 1276 )。所以对 PDGFR的抑制可以预防和治疗上述的疾病。 除了上述的疾病外, 对 PDGFR的抑制还可以治疗各种自身免疫性疾病和炎症疾病 包括糖尿病, 尤其是 I型糖尿病, 类风湿关节炎, 牛皮癣, 和克罗恩病等(Paniagua et al. Nat. Clin. Prac. Rheum. 2007, 3, 190; 和 Louvet et al. Proc. Natl. Acad. Sci. USA, 2008, 105, 18895 )。 本发明提供了一类新的二氢化茚酰胺衍生物, 能够抑制蛋白激酶的活性, 特 别是一个或多个刚才所描述的蛋白激酶。 因此, 这些化合物将有助于预防或治疗与 蛋白激酶活性异常或失控相关的疾病,特别是涉及 Abl, Bcr-Abl, c-Kit和 PDGFR蛋 白激酶活性异常的疾病。 发明内容 本发明提供通式 I化合物:
