  • Compound (II) inhibits the release of inflammatory cytokines in the body and inhibits the formation of new blood vessels, so it can be widely used to treat a variety of diseases including, but not limited to, inflammation, autoimmune disorders, cancer and immune rejection syndrome (see U.S. Patent 5,635,517, 6,281,230, Chinese Patent 200510013292.3).
  • Tumor necrosis factor a is a major cytokine released by mononuclear phagocytes in response to immune stimulation.
  • Administration of TNFa to animals and humans can cause inflammation, fever, cardiovascular dysfunction, hemorrhage, coagulation, and a series of acute reactions similar to acute infections and shock states.
  • Excessive or uncontrolled TNFa in animals or in humans often suggests the following diseases:
  • TNFa also plays an important role in bone resorption disorders including arthritis [Betolinni et al. , Nature
  • Brainstem malaria is also associated with high levels of TNFa in the blood, which is the most dangerous form of malaria. Sickness, serum TNFa levels are directly related to the condition, and often in patients with acute malaria Occurs [Grau et al., N. Engl. J. Med. 320 (24), 1586-91 (1989)].
  • TNFa also plays an important role in chronic pneumonia. Storage of silicon-containing particles in the lungs can cause silicosis. Silicosis is a progressive respiratory failure caused by the fibrosis of the lungs. In animal pathology models, antibodies to TNFa completely block the lung fibrosis process induced by silica dust [Pignet et al., Nature, 344:245-7 (1990)]. Animal experiments have also shown that TNFa is abnormally high in animal serum of pulmonary fibrosis caused by silica dust or asbestos ash [Bissonnette et al., Inflammation 13 (3), 329-339 (1989)].
  • TNFa levels in lung tissue of patients with pulmonary nodules are also much higher than in normal people [Baughman et al., J. Lab. Clin. Med. 115(1), 36-42 (1990)]. It is suggested that TNF ⁇ inhibitors are of great significance in the treatment of chronic lung disease and lung injury.
  • TNFa The cause of inflammation in Reperfusion Injury may also be due to abnormal levels of TNFa in the patient, and TNF a is considered to be the chief culprit in tissue damage caused by ischemia [Uadderetal., P. AS 87 , 2643 -6 (1990) ]
  • TNFa can initiate replication of retroviruses including HIV-1 [Duh et al., Proc. Nat. Acad. Sci., 86, 5974-8 (1989)].
  • T_ cells need to be activated before HIV enters T-cells, and once activated T-cells are infected with HIV, these T-cells must remain active to allow the HiV viral gene to be successfully expressed and/or to replicate HIV. .
  • Cytokines, especially TNFa play an important role in the expression of HIV proteins regulated by T_ cells or in viral replication. Therefore, inhibition of TNFa production may inhibit the replication of HIV virus in T- cells. [Poll et al., Proc. Nat. Acad. Sci., 87, 782-5 (1990); Monto et al..'; Blood 79, 2670 (1990); Pol l et al., AIDS Res. Human Retrovirus , 191-197 (1992)].
  • cAMP regulates many cell-like functions, such as inflammatory reactions, including asthma and inflammation [Lome and Cheng, Drugs of the futune, 17 (9), 799-807, 1992].
  • An increase in the cAMP concentration of leukocytes during inflammation inhibits leukocyte activation, followed by the release of inflammatory regulatory factors, including TNFa, which exacerbate inflammation in the patient. Therefore, inhibition of TNFci release can alleviate inflammatory diseases including asthma.
  • Li Yingxu et al found that the levels of monocyte synthesis and secretion of tumor necrosis factor in peripheral blood of patients with chronic liver disease were significantly increased, and induced the secretion of other cytokines (such as ⁇ -1 ⁇ , ⁇ -6 and 11-8) and participated in hepatocytes.

  • TNFa inhibitors can significantly inhibit the secretion of TNFa from peripheral blood mononuclear cells in patients with hepatitis, thus laying a molecular pathological basis for the treatment of hepatitis, cirrhosis and liver cancer with TNFa inhibitors.
  • TNFa promotes the expression of cell adhesion molecules by promoting the synthesis and release of inflammatory cytokines [Abboud HE Kidney Int. 1993; 43:252-267] [Egido J. et al, Kidney Int. 1993; 43 (suppl 39) : 59-64], and stimulate the synthesis and release of prostaglandin G 2 (PGEJ and platelet activating factor (PAF) [Cammusi G. et al., Kidney Int., 43 (suppl 39): 32-36], making inflammation Cell aggregation and adhesion, microvascular dilatation and permeability enhancement, induction of fever, inflammatory neutrophil increase and hemodynamic changes, resulting in renal cell damage Injury. Many studies suggest that TNF a plays an important role in the pathogenesis and deterioration of nephritis.
  • TNF a participates in the regulation of immune function by activating macrophages, immunostimulating T lymphocyte proliferation, regulating B lymphocyte differentiation and enhancing the cytotoxicity of natural killer cells (NK).
  • NK natural killer cells

或盐的多晶型物及其制备和应用
技术领域
本发明涉及 3-(4-氨基 -1-氧代 -1,3-二氢异吲哚 -2-基)哌啶 -2,6-二酮与各种酸生成的盐或这 些盐的溶剂化物、 盐或盐的溶剂化物的多晶型物、 及其制备方法和在制备用于治疗由抑制炎 症因子或新生血管生成可达成疗效的那些疾病的药物中的应用。
背景技术
3-(4-氨基 -1-氧代 -1,3-二氢异吲哚 -2-基)哌啶 -2,6-二酮 (11, 其中 Y表示 H)具有多重的药 理作用。 化合物 (II) 可抑制体内炎症因子的释放, 还可抑制新生血管的生成, 因而可广泛 用于治疗多种疾病, 包括但不限于炎症、 自身免疫异常类疾病、 癌症和免疫排斥综合症 (见 美国专利 5635517、 6281230、 中国专利 200510013292.3 )。

(II)
肿瘤坏死因子 a (TNFa ) 是由单核噬细胞在应答免疫刺激时释放出的主要细胞素。 对 动物和人施用 TNFa 可引起炎症、 发热、 心血管功能异常、 出血、 凝血和一系列与急性感染 及休克状态相类似的急性反应。 动物体内或人体内产生过量的或者不受控制的 TNFa 常提示 患有如下疾病:
1、 内毒素血症和 /或中毒休克综合症 [Tracey et al., Nature 330, 662-41987; Hinshaw et al., Circ Shock 30, 279- 92 (1990) ];
2、 恶病质 [Dezube et al. , Laucet , 335(8690) , 662(1990)) ];
3、 成人呼吸紧张综合症(ARDS) [Millar et al., Laucet 2(8665), 712-714(1989)]。
TNFa 也在包括关节炎在内的骨吸收类疾症中起重要作用 [Betolinni et al. , Nature
319 , 516-8 (1986)]。 体外和体内试验均证明 TNF α 可通过刺激破骨细胞(Osteoclast)的生 成和激活来刺激骨再吸收, 并抑制骨的生成。
至今, 与 TNFa 关系最明显的疾病是肿瘤和宿主组织释放 TNF α 与恶性肿瘤相关的高钙 血症 [Calci. Tissue Int. (US)46(Suppl. ), S3- 10(1990) ]。 在骨髓移植病人身上, 免疫反 应与病人血清 TNFa 浓度增加紧密相关 [Holler et al., Blood , 75(4), 1011- 1016(1990) ]。
致死性超急性神经性综合症脑干型疟疾也与血液中 TNFa 水平高有关, 该病是疟疾类疾 病中最危险的一种。 病发吋, 血清 TNFa 水平与病情直接相关, 并常可在急性疟疾发作病人 身上发生 [Grau et al. , N. Engl. J. Med. 320(24), 1586- 91 (1989) ]。
TNFa 在慢性肺炎中亦起着重要作用。 肺中含硅微粒的贮存可引起硅肺。 硅肺是由肺组' 织的纤维化反应而引起的进行性呼吸衰竭症。 在动物病理模型中, TNFa 的抗体可完全阻断 硅尘引起的小鼠肺纤维化过程 [Pignet et al. , Nature ,344:245-7 (1990)]。 动物实验也 证明在硅尘或石棉灰引起的肺纤维化的动物血清中 TNFa 异常高 [Bissonnette et al., Inflammation 13 (3), 329- 339 (1989) ]。 病理研究揭示肺结节病人肺组织中的 TNFa 水平也 比平常人要高得多 [Baughman et al. , J. Lab. Clin. Med. 115(1) , 36 - 42 (1990) ]。 提示 TNF α 抑制剂在慢性肺病和肺损伤的治疗上有重大意义。
在再灌注损伤病人(Reperfusion Injury)中引起炎症的原因也可能由于病人体内 TNFa 水平异常,并且 TNF a 被认为是引起缺血所导致的组织损伤的罪魁祸首 [Uadderetal., P. AS 87 , 2643-6 (1990) ]
此外, 实验证明 TNFa 可启动包括 HIV- 1在内的逆转录病毒的复制 [Duh et al., Proc. Nat. Acad. Sci., 86,5974-8(1989)]。 HIV进入 T-细胞前需激活 T_细胞, 并且一旦被激活 的 T-细胞被 HIV病毒感染, 这些 T-细胞必须继续保持在激活状态才能使 HiV病毒基因顺利 表达和 /或让 HIV病毒顺利复制。 而细胞素, 特别是 TNFa , 在 T_细胞调控的 HIV蛋白表达 过程中或病毒复制过程中起着重要作用。 因此, 抑制 TNFa 的生成便可能抑制 HIV病毒在 T-- 细胞中的复制。 [Poll et al. , Proc. Nat. Acad. Sci. , 87, 782-5(1990); Monto et al..'; Blood 79,2670(1990); Pol l et al. , AIDS Res. Human Retrovirus ,191-197(1992)]。
cAMP可调节很多类细胞功能, 比如炎症反应, 包括哮喘、 发炎 [Lome and Cheng, Drugs of the futune , 17 (9) , 799-807, 1992]。 发炎时白细胞的 cAMP浓度的升高抑制了白细胞的 激活, 随后释放出炎症调控因子, 包括 TNFa , 而加剧病人体内炎症。 因此, 抑制 TNFci 的 释放可缓解包括哮喘在内的炎症类疾病。
最近, 于岩岩等发现 TNFa 在病毒性肝炎病人的肝坏死进程中起着重要作用 [于岩岩等, 中华内科杂志 1996, 35: 28-31], 提示 TNF a 抑制剂在慢性肝病和肝损伤的治疗中有重大意 义。
李应续等发现慢性肝病患者外周血单核细胞合成和分泌肿瘤坏死因子的水平明显增高, 且诱导其它细胞因子(比如 Π-1 β, Π- 6和 11-8)的分泌,并共同参与肝细胞的损伤过程 [齐 齐哈尔医学院学报, 22 ( 10 ) : 1119-1120 , 2001]。 他们的结果与 Yoshioka 等 [Hepatology , 1989, 10:769-777] 和王新等 [中华传染病杂志, 1997, 15 (2): 85-88] 的 研究结论符合。 他们进而发现小分子 TNFa 抑制剂反应停可显著地抑制肝炎病人外周血单核 细胞分泌 TNFa , 从而为 TNFa 抑制剂用于治疗肝炎、肝硬化及肝癌奠定了分子病理学基础。
TNFa 通过促使炎症性细胞因子的合成与释放 [Abboud H. E. Kidney Int. 1993; 43:252-267] , 促使细胞粘附分子的表达 [Egido J. et al, Kidney Int. 1993;43(suppl 39): 59-64], 及刺激前列腺素 G2 (PGEJ和血小板活化因子(PAF)的合成和释放 [Cammusi G. et al., Kidney Int., 43(suppl 39) :32-36], 使炎症细胞聚集与粘附, 微血管扩张与通透性 增强, 诱发发热, 循环中性粒细胞增加及血液动力学改变等炎性反应, 从而引起肾细胞的损 伤。 很多研究提示 TNF a 在肾炎的发病及恶化中起着重要的作用。
TNF a 通过激活巨噬细胞, 免疫性刺激 T淋巴细胞增生, 调节 B淋巴细胞的分化及增强 自然杀伤细胞 (NK) 的细胞毒性作用, 从而参与了免疫功能的调节。
因而, 降低病人体内 TNF a 水平和 /或增加其 cAMP水平是一个有效的策略来治疗很多炎 症性、 感染性、 免疫性或恶性肿瘤类疾病, 包括但不限于败血症性休克 (Sepsis Shock)、 内 毒素休克、 血液动力性休克(Hemodynamic Shock)、 脓毒症(Sepsis Syndrom)、 后局部缺血 再灌注损伤(Post Ischemic Reperfusion Injury)、 疟疾(Malaria)、 分支杆菌感染 (Mycobacterial Infection)、 脑膜炎(Meningitis)、 银屑病(Psoriasis)、 充血性心脏衰竭 (Congestive Heart Fail ure)、 纤维化疾病(Fibrotic disease)、 恶病质(Cachexia)、 移植 免疫排斥、.癌症、 自身免疫病(Autoimmune disease)、 AIDS的机会致病感染(Opportu i stic Infection in AIDS)、 类风湿性关节炎 (RA)、 肝炎、 肾炎、 类风湿性脊椎炎(Rheumatoi d Spondyl itis)等。
有文献报道帕金森氏症病变部位炎症因子,尤其是 TNF含量异常高,在帕金森氏症病理 模型上,抑制 TNF释放可逆转病程进展,提示抗 TNF疗法有可能治愈帕金森氏症 (McCoy, M. The Journal of Neuroscience, Sept. 13, 2006; vol 26)。
Enbrel, 可溶性的 TNF受体, 对关节炎、 牛皮癣有较好疗效, 提示 TNF抑制剂可治疗关 节炎、 牛皮癣。
反应停在临床上对小儿脑膜炎有良好药效, 提示 TNF抑制剂可治疗脑膜炎。 : 中国医生观察到肝炎病变部位 TNF水平异常高, 并进一歩揭示 TNF在肝纤维化和肝硬 : 化进程中起着核心作用, 提示 TNF抑制剂可用于治疗肝炎和肝硬化。
于等观察到肾炎病人血液中 T F水平偏高, 提示抗 TNF疗法可能对肾炎治疗有效。 综上所述, TNF拮抗剂可用于治疗那些可由控制 TNF水平而可得到治疗的疾病, 包括但 不限于关节炎、 肝炎、 胃炎、 消化道溃疡、 口腔溃疡、 肾炎、 鼻炎、 支气管炎、 COPD (慢 性阻塞性肺病)、 肺炎、 肺结核、 心肌炎、 胰腺炎、 前列腺炎、 宫颈炎、 肠炎、 克郎综合症、 神经末梢炎、 脊髓炎、 脑炎、 帕金森氏症、 牛皮癣、 红斑狼疮、 顽固性皮炎、 麻风病、 帕金 森氏症、 进行性脑荽缩症、 阿尔茨海默病、 肝硬化。 因此, 低毒、 高效的小分子 TNF a 抑制 剂的研制具有极大的社会意义和经济价值。
式(II )化合物还可抑制新生血管的生成, 因而可广泛用于治疗多种疾病, 包括但不限于 癌症, 包括但不限于骨髓癌、 白血病、 肝癌、 脑瘤、 前列腺癌、 胃癌、 食道癌、 肠癌、 咽喉 癌、 口腔癌、 鼻癌、 骨癌、 宫颈癌、 肺癌、 乳腺癌、 肾癌、 淋巴瘤、 卵巢癌、 胰腺癌、 肾上 腺癌、 间皮细胞癌、 黑色素瘤、 骨髓增生异常综合症。
化合物 (II ) 的水溶性较差。 美国细胞基因公司研究了化合物 (II) 的各种水合物和晶型 (见世界专利 WO2005/023192 ), 并配合微粉化技术, 最终成功研发一种胶囊制剂, 被 FDA 批准上市。
对特定的人群, 口服制剂可能达不到具有疗效意义的药物生物利用度, 尤其是象式 (Π .) 化合物这样水溶性极低的药物, 注射用药能使所有病人达到 100%的生物利用度。 从化合物(II) 的化学结构特点和 pKa分析可得出化合物(Π)不易与酸作用生成相应的 盐, 反而易与碱反应生成金属盐, 比如钠盐、 钾盐或钙盐的结论。 然而, 化合物 (Π ) 在碱 性条件下不稳定, 易水解。 因而, 迄今尚未见有关化合物 (II) 的盐的报道。
众所周知, 把自由碱形式的药物分子制备成盐, 不仅可大大提高药物分子的水溶性及其 口服生物利用度, 而且还为把药物制备成可经非口服方式给药, 比如静脉给药、肌注、 吸入、 滴剂提供了可能。 把自由碱形式的药物分子制备成盐也为制备控释制剂提供了更多选择。 此 外, 成盐形式的药物分子可能具备更好的稳定性、 可加工性等等制剂制备工艺上的优越性。
把自由碱形式的药物分子制备成盐也为研发可为各国药政管理机构接受的原料药纯化 方法提供了可能。 制备成盐的药物可方便地在以水、 醇、 酮为代表的安全溶剂中重结晶而得 到高品质的原料药产品。 因而, 把自由碱形式的药物分子制备成盐通常是原料药物质形态 ( drug substance ) 的最佳选择。
综上所述,成功研发 3-(4-氨基 -1-氧代 -1 3-二氢异吲哚 -2-基)哌啶 -2 6-二酮的盐很有必要。 发明内容
