Definitions

  • the present invention relates to a novel class of amide derivatives, a process for the preparation thereof, and a pharmaceutical composition containing the same, and the use thereof as a therapeutic agent, particularly as a microsomal prostaglandin E synthetase-1 (mPGES-1) inhibitor And use in the manufacture of a medicament for the treatment and/or prevention of a disease or condition such as inflammation and/or pain.
  • mPGES-1 microsomal prostaglandin E synthetase-1
  • Inflammatory diseases affecting people include asthma, inflammatory bowel disease, rheumatoid arthritis, osteoarthritis, rhinitis, conjunctivitis and dermatitis. Inflammation is also a common cause of pain, which can be caused by a variety of causes, such as infections, surgery or other trauma. At the same time, some diseases including malignant tumors and cardiovascular diseases also have symptoms of inflammation.
  • Prostaglandin E2 is one of the most common prostaglandins (PG). It is a strong pro-inflammatory mediator that induces fever and pain and participates in various physiological and pathophysiological processes. Its chemical synthesis consists of three consecutive enzymatic reactions: (1) arachidonic acid (AA) is liberated from phospholipids on the membrane by phospholipase A2 (PLA2); (2) AA produces PGG2 and PGH2 under the action of cyclooxygenase (COX); (3) PGE2 synthase (PGES) catalyzes PGH2 production of PGE2, PGF2, PGD2, prostacyclin and thromboxane A2.
  • AA arachidonic acid
  • PAG2 phospholipase A2
  • COX cyclooxygenase
  • PGES PGE2 synthase
  • COX cyclooxygenase
  • COX-1 and/or COX-2 inhibitors have been shown to inhibit inflammation by ultimately reducing PGE2 formation, such as "NSAID” (non-steroidal anti-inflammatory drugs) and "coxib” (selective COX-2 inhibitors).
  • NSAID non-steroidal anti-inflammatory drugs
  • coxib selective COX-2 inhibitors
  • target COX reduces the formation of all metabolites of arachidonic acid (AA), which contain beneficial ingredients for the human body, so COX inhibitors may have adverse biological effects on the human body. Therefore, the development of new drugs that are safer and more effective for inflammatory diseases has great clinical significance and market value.
  • the enzyme system PGES that directly targets PGE2 synthesis is the terminal rate-limiting enzyme in the PGE2 synthesis process.
  • PGES cytosolic PGES
  • PGES-3 membrane-bound PGES-1
  • mPGES-2 membrane-bound PGES-2
  • cPGES is a GSH-dependent constitutive enzyme, an enzyme widely expressed in various tissues and cells by housekeeping genes, and is not affected by inflammatory stimulators.
  • mPGES-2 is a GSH-independent constitutive enzyme mainly expressed in tissues with relatively low expression of mPGES-1, such as brain, heart, kidney, small intestine, etc., and is not induced by tissue inflammation and damage.
  • mPGES-1 is a GSH-dependent inducible expression of an enzyme that can be expressed by proinflammatory cytokines and expressed in large quantities in pathophysiological processes in various diseases such as arthritis, inflammation-related fever and pain, atherosclerosis and cancer. Focus on To be effective.
  • the human mPGES-1 gene is located on chromosome 9q34.3 and comprises three exons and two introns, approximately 14.8 kb in length, and the cDNA encodes a polypeptide of 152 amino acids.

Description

酰胺类衍生物及其可药用盐、其制备方法及其在医药上的应用 技术领域
本发明涉及一类新型酰胺类衍生物、其制备方法及含有该衍生物的药物组合物,以及其作为治疗剂特别是作为微粒体前列腺素E合成酶-1(mPGES-1)抑制剂的用途和在制备治疗和/或预防炎症和/或疼痛等疾病或病症的药物中的用途。
背景技术
许多疾病和/或失调实质上是炎性的,与现有的治疗炎性疾病有关的一个主要问题是缺乏功效和/或普遍存在的副作用。影响人们的炎性疾病包括哮喘、炎性肠病、类风湿性关节炎、骨关节炎、鼻炎、结膜炎和皮炎等。炎症也是疼痛的一种普遍原因,炎性疼痛可以由多种原因引起,如感染、外科手术或其他外伤。同时,包括恶性肿瘤和心血管疾病在内的一些疾病也有炎症的症状。
前列腺素E2(prostaglandin E2,PGE2)是一种最常见的前列腺素(PG),属强促炎性介质,可诱导发热和疼痛,参与机体多种生理及病理生理过程。它的化学合成由三个连续的酶促反应组成:(1)花生四烯酸(arachidonic acid,AA)在磷脂酶A2(phospholipase A2,PLA2)的催化下从膜上的甘油磷脂中释放出来;(2)AA在环氧合酶(cyclooxygenase,COX)的作用下生成PGG2和PGH2;(3)PGE2合酶(prostaglandin E2synthase,PGES)催化PGH2生成PGE2、PGF2、PGD2、前列环素和凝血恶烷A2。
环氧合酶(COX)存在两种形式,一种在许多细胞和组织中组成型表达COX-1,一种在炎性反应期间通过促炎性刺激例如细胞因子来诱导COX-2。目前已有多种COX-1和/或COX-2抑制剂通过最终降低PGE2的形成来抑制炎症,如“NSAID”(非甾类抗炎药)和“coxib”(选择性COX-2抑制剂)。然而抑制靶点COX会减少花生四烯酸(AA)的所有的代谢物的形成,这些代谢物中包含对人体有益的成分,因此COX抑制剂可能会对人体造成不利的生物学作用。因此,开发对炎性疾病更为安全有效的新药具有重大的临床意义和市场价值。
直接靶向PGE2合成的酶系PGES是PGE2合成过程的末端限速酶,目前已知至少有3种PGES,即胞质型PGES(cPGES)或称PGES-3、膜结合型PGES-1(mPGES-1)和膜结合型PGES-2(mPGES-2)。cPGES是GSH依赖性的组成型酶,属管家基因在多种组织和细胞中广泛表达的酶,不受炎症刺激因子的影响。mPGES-2是GSH非依赖性的组成型酶,主要表达于mPGES-1表达相对较低的组织,如脑、心脏、肾、小肠等,不由组织炎症和损伤所诱导。mPGES-1属于GSH依赖性的诱导型表达的酶,能被致炎因子诱导而大量表达,在多种疾病,如关节炎、炎症相关性发热和疼痛、动脉粥样硬化及癌症的病理生理过程中均发挥着重 要作用。人mPGES-1基因位于染色体9q34.3,包括三个外显子和两个内含子,长约14.8kb,其cDNA编码一条含152个氨基酸的多肽。不同种属的mPGES-1蛋白一级结构具有80%以上的同源性。研究发现,在致炎因子(LPS,IL-1等)刺激下,多种培养细胞中的COX-2和mPGES-1表达明显增加,同时伴有PGE2合成增加,同时,免疫组化实验显示,COX-2和mPGES-1都定位于微粒体膜上,提示mPGES-1主要与COX-2偶联,在炎症因子引起的迟发型反应中共同介导PGE2的合成增加。然而,酶促动力学研究发现,COX-2和mPGES-1的诱导作用并不完全一致,某些情况下COX-2还可与mPGES-2偶联,而mPGES-1有时也可与COX-1偶联,而COX-2催化产生的PGH2除在mPGES-1作用下合成PGE2,还可合成其它类型的前列腺素,因此COX-2和mPGES-1表达的调节机制既有重叠又有区别。
目前处于临床阶段的mPGES-1抑制剂有韩国GNT(Neurotech)制药的AAD-2004和Eli Lilly公司的LY-3023703。AAD-2004的适应症并不针对疼痛,而是治疗阿尔茨海默病、帕金森氏症和运动神经元病的一种强效自旋捕获分子和微粒体前列腺素E合酶-1抑制剂。LY-3023703用于治疗骨关节炎疼痛,于2012年6月进入一期临床阶段,目前为止,Eli Lilly公司有关mPGES-1项目只公开两篇专利WO2012087771和WO2012161965。
尽管目前已公开了一系列的微粒体前列腺素E合成酶-1(mPGES-1)抑制剂,但仍需要开发新的具有更好的药效的化合物,经过不断努力,本发明设计具有通式(I)所示的结构的化合物,并发现具有此类结构的化合物表现出优异的效果和作用。
