Definitions

  • the present invention relates to the field of medicinal chemistry, in particular to a series of novel benzothiazole derivatives and their pharmaceutically acceptable salts, solvates or prodrugs, their preparation methods and pharmaceutical compositions containing the compounds.
  • the present invention also relates to the application of such compounds in the preparation of drugs for the treatment and/or prevention of sEH-mediated diseases, especially in the preparation and treatment of inflammatory diseases, cardiovascular and cerebrovascular diseases, diabetes, diabetic complications, and diabetes Application in medicines for related diseases, fibrotic diseases, neurological and mental diseases, pain, ulcer diseases, etc.
  • Epoxide hydrolase ubiquitously exists in mammals, insects, plants and microorganisms, and is an enzyme widely distributed in nature. At present, epoxide hydrolases are divided into 8 types according to their activity, biochemical characteristics and current research results. Soluble epoxide hydrolase (sEH) is one of the more in-depth studies of epoxide hydrolase at this stage. It was first studied by Gill et al. in 1973 when they were studying the metabolism of terpene epoxides similar to insect juvenile hormones. Found, it is named because it is located in the soluble components of cells such as cytoplasm and peroxisomes. In recent years, a large number of studies have shown that soluble epoxide hydrolase is a potential therapeutic target for many diseases such as hypertension, lung disease, diabetes, pain, inflammation and other immune system diseases.
  • Human sEH is encoded by the EPHX2 gene, which is located in the P21-P12 region of human chromosome 8. It consists of 19 27-265bp exons and 18 introns, with a total length of about 45kb and a total of 555 amino acid residues. . sEH is expressed in almost all organs, including liver, kidney, lung, heart, brain, spleen, adrenal gland, intestine, bladder, vascular endothelium, smooth muscle, white blood cells and ovarian cells. Its activity is highest in the liver and second in the kidneys. sEH plays an important role in lipid epoxide metabolism. Its endogenous substrates include epoxyeicosatrienoic acids (EETs).
  • EETs epoxyeicosatrienoic acids
  • EETs are a class of endogenous chemical mediators that have been proven It has a variety of physiological functions, such as dilating blood vessels, lowering blood pressure, regulating lipid metabolism and insulin resistance, etc. (Q. Wang, W. Pang, Z. CuI, American Journal of physiology-Renal physiology, 2013, 304: 168-176) . Studies have found that the EETs in the body can be rapidly hydrolyzed into dihydroxyeicosatrienoc acids (DHETs) by the action of sEH and lose their activity. Therefore, how to inhibit the activity of sEH has become a critical issue. In recent years, studies have shown that small molecule inhibitors or gene knockout techniques can be used to reduce the activity of sEH to stabilize or increase the content of EETs.
  • DHETs dihydroxyeicosatrienoc acids
  • EETs are activators that inhibit nuclear transcription factor (NF- ⁇ B).
  • NF- ⁇ B nuclear transcription factor
  • sEH can improve and control inflammation.
  • respiratory tract inflammation caused by tobacco smoke and monocrotaline-induced pulmonary hypertension can also reduce the severity of sEH by inhibiting sEH.
  • sEH inhibitors also have a certain analgesic effect.

Description

苯并噻唑类衍生物及其用途 技术领域
本发明涉及药物化学领域,特别涉及一系列新型的苯并噻唑类衍生物及其药学上可接受的盐、溶剂化物或前药,它们的制备方法以及含有所述化合物的药物组合物。本发明还涉及该类化合物用于制备治疗用于治疗和/或预防sEH介导的疾病的药物中的应用,特别是在制备治疗炎症性疾病、心脑血管疾病、糖尿病、糖尿病并发症、糖尿病相关疾病、纤维化疾病、神经及精神疾病、疼痛、溃疡性疾病等的药物中的应用。
背景技术
环氧化物水解酶(epoxide hydrolase,EH)普遍存在于哺乳动物、昆虫、植物和微生物生物体内,是广泛分布于自然界的一种酶类。目前,根据酶的活性、生化特征以及当前的研究结果将环氧化物水解酶分为8种。可溶性环氧化物水解酶(soluble epoxide hydrolase,sEH)作为现阶段研究较为深入的环氧化物水解酶之一,最早于1973年由Gill等在研究类似昆虫保幼激素萜类环氧化物的代谢时发现,因其位于细胞的可溶性成分如细胞质和过氧化物酶体中而命名。近年来大量的研究表明,可溶性环氧化物水解酶是高血压、肺部疾病、糖尿病、疼痛、炎症和其他免疫系统疾病等许多疾病潜在的治疗靶点。
人类sEH由EPHX2基因编码,该基因位于人类8号染色体的P21-P12区域,由19个27-265bp的外显子和18个内含子构成,全长约45kb,共编码555个氨基酸残基。sEH几乎在所有的器官中都有表达,已发现的有肝脏、肾脏、肺、心脏、大脑、脾、肾上腺、肠、膀胱、血管内皮、平滑肌、白细胞和卵巢细胞等。其活性在肝脏中最高,肾脏中次之。sEH在脂质环氧化物代谢中起重要作用,它的内源性底物包括环氧二十碳三烯酸(epoxyeicosatrienoic acids,EETs),EETs是一类内源性的化学介质,已被证明具有多种生理功能,如扩张血管,降低血压,调节脂质代谢和胰岛素抵抗等(Q.Wang,W.Pang,Z.CuI,American Journal of physiology-Renal physiology,2013,304:168-176)。研究发现,机体内的EETs经sEH的作用可被迅速水解成二羟基二十碳三烯酸(dihydroxyeicosatrienoc acids,DHETs)从而失去活性。因此如何抑制sEH的活性成为一个关键性的问题。近年来,有研究表明,可以通过小分子抑制剂或基因敲除技术降低sEH的活性,以稳定或增加EETs的含量。
抑制sEH所获得的药理作用可用细胞内EETs的水平含量来衡量,关于sEH抑制剂的研究主要集中在对血管和炎症的影响。EETs是抑制核转录因子(NF-κB)的激活剂,在患有炎症的动物模型实验中,抑制sEH便可以改善和控制炎症。此外,在动物炎症模型中,因烟草烟雾引起的呼吸道炎症和野百合碱诱导的肺动脉高压,也可通过抑制sEH来降低严重程度。sEH抑制剂也具有一定的镇痛作用。在脑缺血的动物模型实验中,抑制sEH活性可以抑制缺血性炎症反应,刺激抗神经元基因表达的凋亡,减少脑梗塞的效果(A.Cautaux,F.Adam,C.J.Willer,Joint Bone Spine,2005,72:359-371)。
研究发现sEH的催化位点存在一个关键的天冬氨酸残基,故早期sEH抑制剂的研究主要集中在羧基的修饰试剂上。二环己基碳化二亚胺(DCC)作为酰胺键以及肽合成中的常用试剂,能够与羧酸发生反应,生成相应的酯。于是人们意外的发现DCC对sEH具有较好的抑制活性。但是随后根据药代动力学分析,DCC在溶液中会水解成相应的脲,后者是抑制sEH的主要活性物质,故早期的sEH抑制剂大多数都含有脲结构(C.Morisseau,B.D.Hammock,Annual Review of Pharmacology and Toxicology,2005,45:311-333)。t-AUCB由加利福尼大学和UCD癌症中心联合发现的sEH抑制剂,研究发现该化合物对多种哺乳动物和人的sEH都具有较高的抑制活性。
目前有一些活性突出且治疗效果好的化合物处于临床前及临床研究阶段,如AR9281、GSK2256294和EC5026等。EC5026是由加利福尼亚大学Bruce Hammock团队开发的一种脲类sEH抑制剂,该药目前正在进行Ia期临床试验,适应症为神经性疼痛。
