Definitions

  • the present invention relates to a class of PDE4 inhibitors and their use in the manufacture of a medicament for the treatment of a disease associated with PDE4. Specifically, it relates to a compound of the formula (I) and a pharmaceutically acceptable salt thereof.
  • Tumor necrosis factor is a cytokine that is released primarily by mononuclear phage cells in response to immunostimulants. TNF ⁇ promotes most processes such as cell differentiation, recruitment, proliferation, and protein degradation. At low levels, TNF ⁇ has a protective effect against infection, tumors and tissue damage. However, excessive release of TNF ⁇ can also cause diseases, such as administration of TNF ⁇ to mammals or humans, which can cause or aggravate inflammation, fever, cardiovascular effects, hemorrhage, coagulation, and acute reactions similar to acute infection and shock state.
  • TNF ⁇ production in animals or humans often suggests the following diseases: endotoxemia and/or toxic shock syndrome, cachexia, adult respiratory syndrome, cancer (such as solid tumors and hematological tumors) ), heart disease (such as congestive heart failure), viral infection, genetic disease, inflammatory disease, allergic disease or autoimmune disease.
  • Cancer is a particularly devastating disease, and an increase in the level of TNF ⁇ in the blood is predictive of a risk of spreading cancer or cancer.
  • cancer cells cannot survive in the circulatory system of healthy subjects, one of which is that the inner wall of blood vessels is a barrier to extravasation of tumor cells.
  • ELAM-1 on endothelial cells mediates the adhesion of colon cancer cells to the cytokine-treated endothelium.
  • Cyclic adenosine monophosphate plays a role in many diseases and conditions. Increased cAMP concentration in leukocytes during inflammation inhibits leukocyte activation, followed by release of inflammatory regulatory factors including TNF ⁇ and NF- ⁇ B. Increased levels of cAMP also cause relaxation of the smooth muscles of the airways.

技术领域
本发涉及一类PDE4抑制剂,及其在制备治疗与PDE4关疾病的药物中的应用。具体涉及式(Ⅰ)所示化合物及其药学上可接受的盐。
背景技术
肿瘤坏死因子(TNFα)是一种主要由单核噬菌细胞应答免疫刺激物时释放的细胞因子。TNFα能够促进细胞的分化、募集、增殖和蛋白质降解等大多数过程。在低水平下,TNFα具有防止传染物、肿瘤和组织损伤的保护作用。但TNFα释放过多也会引起疾病,如给予哺乳动物或人TNFα时,会引起或加重炎症、发烧、心血管作用、出血、凝血以及与急性感染和休克状态相类似的急性反应。动物体或人体内产生过量的或不受控制的TNFα常提示患有如下疾病:内毒素血症和/或中毒休克综合症、恶病质、成人呼吸紧张综合症、癌症(如实体瘤和血液性肿瘤)、心脏病(如充血性心力衰竭)、病毒感染、遗传疾病、炎性疾病、变应性疾病或自身免疫疾病。
癌症是具有特别破坏性的疾病,血液中TNFα水平的提高预示存在患有癌症或癌症扩散的危险。通常,癌细胞不能在健康主体的循环系统中存活,其中一个原因在于血管内壁是瘤细胞外渗的屏障。研究表明,内皮细胞上的ELAM-1能介导促进结肠癌细胞黏附在用细胞因子处理的内皮上。
环腺苷酸(cAMP)在许多疾病和病症中起作用。发炎时白细胞中cAMP浓度的升高抑制了白细胞的激活,随后释放出包括TNFα和NF-κB等炎症调控因子。cAMP水平提高也会导致呼吸道平滑肌的松弛。
cAMP失活的主要细胞机制是由于被称为环核苷酸磷酸二酯酶(PDE)的一族同工酶破坏了cAMP。已知有11个PDE家族成员。迄今,已证实抑制PDE4酶对抑制炎症介质的释放及对松弛呼吸道平滑肌特别有效,因此PDE4酶已成为热门的药物靶点之一。依据不同的基因编码,PDE-4家族可以分为4个亚型(PDE-4A、B、C、D)。其中,PDE-4A、PDE-4B和PDE-4D在炎症细胞(如B细胞、T细胞和中性粒细胞等)中的表达强于PDE-4C。抑制PDE4酶,导致cAMP水平的升高,从而调节TNFα水平,达到治疗疾病目的。

可以通过的手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D和L异构体。如果想得到本发明某化合物的一种对映体,可以通过不对称合成或者具有手性助剂的衍生作用来制备,其中将所得非对映体混合物分离,并且辅助基团裂开以提供纯的所需对映异构体。或者,当分子中含有碱性官能团(如氨基)或酸性官能团(如羧基)时,与适当的光学活性的酸或碱形成非对映异构体的盐,然后通过本领域所公知的常规方法进行非对映异构体拆分,然后回收得到纯的对映体。此外,对映异构体和非对映异构体的分离通常是通过使用色谱法完成的,所述色谱法采用手性固定相,并任选地与化学衍生法相结合(例如由胺生成氨基甲酸盐)。

术语“活性成分”、“治疗剂”,“活性物质”或“活性剂”是指一种化学实体,它可以有效地治疗目标紊乱、疾病或病症。
“任选”或“任选地”指的是随后描述的事件或状况可能但不是必需出现的,并且该描述包括其中所述事件或状况发生的情况以及所述事件或状况不发生的情况。
术语“被取代的”是指特定原子上的任意一个或多个氢原子被取代基取代,可以包括重氢和氢的变体,只要特定原子的价态是正常的并且取代后的化合物是稳定的。当取代基为酮基(即=O)时,意味着两个氢原子被取代。酮取代不会发生在芳香基上。术语“任选被取代的”是指可以被取代,也可以不被取代, 除非另有规定,取代基的种类和数目在化学上可以实现的基础上可以是任意的。
当任何变量(例如R)在化合物的组成或结构中出现一次以上时,其在每一种情况下的定义都是独立的。因此,例如,如果一个基团被0-2个R所取代,则所述基团可以任选地至多被两个R所取代,并且每种情况下的R都有独立的选项。此外,取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
当一个连接基团的数量为0时,比如-(CRR)0-,表示该连接基团为单键。
当其中一个变量选自单键时,表示其连接的两个基团直接相连,比如A-L-Z中L代表单键时表示该结构实际上是A-Z。
当一个取代基为空缺时,表示该取代基是不存在的,比如A-X中X为空缺时表示该结构实际上是A。当一个取代基的键可以交叉连接到一个环上的两个原子时,这种取代基可以与这个环上的任意原子相键合。当所列举的取代基中没有指明其通过哪一个原子连接到化学结构通式中包括但未具体提及的化合物时,这种取代基可以通过其任何原子相键合。取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。例如,结构单元
