Definitions

  • the present invention relates to the field of biomedicine, specifically to fatty acid binding protein (FABP) 4 and/or 5 inhibitors, and more specifically to indole class of novel FABP4/5 inhibitors.
  • the present invention also relates to methods for preparing such compounds and their use Medical use of FABP4/5 inhibitors.
  • FABPs Fatty acid binding proteins
  • FABP family has many subtypes, among which FABP4 (adipocyte-FABP, A-FABP) and FABP5 (epidermal-FABP, E-FABP) are members of the fatty acid binding protein family.
  • FABP4 is mainly distributed in fat cells and macrophages, accounting for 1% of total fat tissue protein.
  • FABP5 distributes in a wide range of tissues.
  • FABP4/5 is closely related to the occurrence and development of metabolic inflammatory diseases, including atherosclerosis, hyperlipidemia, diabetes and its complications, and non-alcoholic steatohepatitis.
  • FABP4/5 double knockout mice change the lipid transport and composition of cells and systems, resulting in enhanced insulin receptor signaling and increased adenylate activated protein kinase (AMPK) activation in muscle tissue Activity, reduce the expression of liver stearoyl-CoA desaturase 1 (SCD1), improve liver lipid infiltration, and have a strong protective effect on diet-induced insulin resistance, diabetes and its complications, and fatty liver disease (Cell Metab. 2005, 1, 107).
  • AMPK adenylate activated protein kinase
  • FABP4/5 -/- is more effective in protecting vascular disease than FABP4 -/- in apolipoprotein E-deficient (ApoE -/- ) mice (Nat.Med.2001,7,699).
  • FABP4/5 can also mediate inflammation, stabilize leukotriene A4 and promote inflammation (J Lipid Res. 2004, 45, 2138; J Lipid Res. 2004, 279, 7420).
  • genetic mutations in the human FABP4 promoter (T-87C) have been found in genetic studies to reduce the expression of FABP4. Compared with FABP4 wild-type people, people carrying T-87C have a lower risk of coronary heart disease and diabetes. TG levels are also reduced (Proc Natl Acad Sci USA.
  • FABP4 and FABP5 are also closely related to the occurrence and development of a variety of tumors, including breast cancer, ovarian cancer, and prostate cancer, as well as tumor metabolism (Gene. 2018, 676, 171). In summary, FABP4/5 is expected to become a potential target for the treatment of obesity and related metabolic diseases and tumors.
  • FABP4 small molecule inhibitors There are many reports on FABP4 small molecule inhibitors, but they are all in the early stage of biological activity testing. Among them, the FABP4 inhibitor BMS309403 developed by Bristol-Myers Squibb is more in-depth, which can improve atherosclerosis and insulin resistance. Treatment of non-alcoholic steatohepatitis and other diseases (Nature.2007,447,959; Journal of hepatology.2013,58,358), but the safety needs to be further verified. There are relatively few reports on the FABP4/5 dual inhibitor. The FABP4/5 dual inhibitor RO6806051 developed by Roche has strong enzyme inhibitory activity (Bioorg Med Chem Lett.
  • the FABP4/5 dual inhibitor developed by Merck can reduce the levels of triglycerides (TG) and free fatty acids (FFA) in the plasma of mice induced by high-fat diet, and improve the abnormal lipid metabolism (J Lipid Res. 2011, 52, 646) .
  • TG triglycerides
  • FFA free fatty acids
  • FABP3 inhibition may cause cardiotoxicity (FASEB J. 1999, 13, 805). Therefore, there is an urgent clinical need to develop novel FABP4/5 inhibitors with strong selectivity, high activity and low side effects.
  • the purpose of the present invention is to provide an indole compound with FABP4 and/or FABP5 inhibitory activity, as well as a preparation method and medical use thereof.

Abstract

本发明公开了一种具有FABP4/5抑制活性的吲哚类化合物及其制备方法和医药用途,其为结构式如式I所示的化合物、其药学上可接受的盐或酯或溶剂化物。本发明的式I化合物是新型FABP4和/或5抑制剂,可用于制备预防或治疗FABP4和/或5相关疾病的药物。

Description

吲哚类衍生物及其医药用途 技术领域
本发明涉及生物医药领域,具体涉及脂肪酸结合蛋白(FABP)4和/或5的抑制剂,更具体涉及吲哚类新型FABP4/5抑制剂,本发明还涉及该类化合物的制备方法及其作为FABP4/5抑制剂的医药用途。
背景技术
脂肪酸结合蛋白(fatty acid binding proteins,FABPs)作为细胞内脂质伴侣蛋白,能够与脂质发生可逆结合,增加其在细胞质中的溶解性,降低脂毒性。FABP家族亚型较多,其中FABP4(adipocyte-FABP,A-FABP)和FABP5(epidermal-FABP,E-FABP)是脂肪酸结合蛋白家族的成员。FABP4主要分布在脂肪细胞和巨噬细胞中,占到脂肪组织蛋白总量的1%。FABP5分布的组织范围较广。FABP4/5与代谢性炎症疾病的发生发展密切相关,包括动脉粥样硬化、高血脂症、糖尿病及其并发症、非酒精性脂肪肝炎等。1996年,Hotamisligil等首次报道了FABP4敲除(FABP4 -/-)的小鼠,其在高脂饮食等代谢应激的条件下,能够表现出良好的胰岛素敏感性,与对照组相比,FABP4 -/-小鼠的脂肪组织中肿瘤坏死因子-α(TNF-α)表达也显著下调,但在脂肪细胞中FABP5的表达发生代偿性增加(Science 1996,274,1377)。FABP4/5双敲除(FABP4-5 -/-)小鼠改变了细胞和系统的脂质运输和组成,导致胰岛素受体信号增强,增加肌肉组织中腺苷酸活化蛋白激酶(AMPK)的激动活性,减少肝脏硬脂酰辅酶A去饱和酶1(SCD1)的表达,改善肝脏的脂质浸润,对饮食诱导的胰岛素抵抗、糖尿病及其并发症和脂肪肝疾病具有很强的保护作用(Cell Metab.2005,1,107)。另外在载脂蛋白E缺失(ApoE -/-)小鼠中FABP4/5 -/-比FABP4 -/-保护血管病变的效果更加显著(Nat.Med.2001,7,699)。FABP4/5还能介导炎症,能够稳定白三烯A4而促进炎症反应(J Lipid Res.2004,45,2138;J Lipid Res.2004,279,7420)。另外在遗传学研究中发现人类FABP4启动子的遗传变异(T-87C)使FABP4的表达降低,与FABP4野生型人群相比,携带T-87C的人群患冠心病及糖尿病的概率降低,其血清TG水平也降低(Proc Natl Acad Sci USA.2006,103,6970)。FABP4和FABP5还与多种肿瘤包括乳腺癌、卵巢癌、前列腺癌等的发生发展以及肿瘤代谢密切相关(Gene.2018,676,171)。综上所述,FABP4/5有望成为治疗肥胖及相关代谢性疾病和肿瘤的潜在靶标。
目前针对FABP4小分子抑制剂的报道有很多,但都处于早期生物活性测试阶段,其中对百时美施贵宝公司研发的FABP4抑制剂BMS309403的研究较为深入,其能够改善动脉粥样硬化和胰岛素抵抗,治疗非酒精性脂肪肝炎等疾病(Nature.2007,447,959;Journal of hepatology.2013,58,358),但安全性有待进一步验证。而对于FABP4/5双重 抑制剂的报道则比较少,罗氏公司研发的FABP4/5双重抑制剂RO6806051具有较强的酶抑制活性(Bioorg Med Chem Lett.2016,26,5092),但对其体内疗效尚未报道,且该化合物的毒副作用较大。默克公司研发的FABP4/5双重抑制剂能够降低髙脂饮食诱导的小鼠血浆中甘油三酯(TG)和游离脂肪酸(FFA)水平,改善脂质代谢异常(J Lipid Res.2011,52,646)。此外,有文献报道FABP3受到抑制可能会引起心脏毒性(FASEB J.1999,13,805)。因此,临床上亟需开发选择性强、活性高且毒副作用小的新型FABP4/5抑制剂。

合成路线1.
Figure PCTCN2020093334-appb-000043
首先,以取代的苯胺为原料,在亚硝酸钠和二氯化锡条件下,得到相应的苯肼盐酸盐,然后在酸性条件下与丙酮酸乙酯,经过Fisher吲哚合成法,得到单一或两个吲哚异构体的混合物,无需纯化直接投下一步,通过Chan-Evans-Lam偶联反应,与芳基硼酸室温下反应,在吲哚1位引入芳基。该反应是随着空气中的氧不断地氧化铜而进行反应的,在不活性气体的保护下反应很难进行。溶液中氧气的浓度决定反应的进程,所以往往收率随着搅拌效率而有所差异。然后,将所得化合物或一对异构体的混合物在碘苯二乙酸酯和对甲苯磺酸条件下,与叠氮化钠经铜催化形成杂芳基碘叠氮化物,再通过含水硫化铵还原得到相应的3-氨基吲哚类化合物。互为异构体的3-氨基吲哚类化合物能够通过柱层析分离得到纯品。相应的3-氨基吲哚类化合物在碱性条件下,与碘乙烷发生亲核取代,所得产物再经过氢氧化钠或氢氧化钾加热水解得到目标产物。
合成路线2.
Figure PCTCN2020093334-appb-000044
通过叠氮基乙酸酯与芳香醛缩合可以得到2-叠氮基-3-芳基丙烯酸酯,其加热环合生成吲哚2-羧酸酯衍生物。由于反应放出氮气,在环合时一定要严格控制2-叠氮基-3-芳基丙烯酸酯滴加速度同时反应瓶敞口,否则反应液很容易喷出。所得吲哚与芳基硼酸在室温下通过Chan-Evans-Lam偶联反应在吲哚1位引入芳基,再经过N-溴代丁二酰亚胺(NBS)在吲哚2位引入溴。所得的芳香溴代物经过Buchwald-Hartwig反应或Suzuki反应在吲哚2位引入胺基、烷氧基或烷基。最后,在碱性条件下加热水解得到目标产物。

Figure PCTCN2020093334-appb-000050
利用N-溴代琥珀酰亚胺在苯胺上选择性的上溴,通过Fischer吲哚合成合成单一吲哚,随后用氢钯碳脱溴,通过Buchwald偶联后再水解得到终产物。
在上述合成路线中,R 1、R 2、R 3、R 4、R 5、R 6、R 7、R 11、R 12、R 13、X和m的定义与上述式I化合物中的定义一致。
在本发明的预防或治疗FABP4和/或5介导的疾病的药物中,式I化合物或其药学上可接受的盐或酯或溶剂化物的量可根据患者年龄、体重、症状和给药途径等而适当改变。当给成人(约60kg)口服给药时,式I化合物或其药学上可接受的盐或酯或溶剂化物的给药剂量优选是1mg~500mg/次,更优选5mg~60mg/次,每天给药1~3次。也可根据疾病程度的不同和剂型的不同而偏离此剂量范围。
有益效果:与现有技术相比,本发明具有如下优点:
(1)本发明的新型吲哚类化合物可以显著抑制FABP4和/或FABP5,且对FABP3抑制活性弱,因而可避免抑制FABP3带来的潜在心脏毒性。本发明的吲哚类化合物作为新型FABP4/5抑制剂,可用于制备预防或治疗FABP4/5相关疾病的药物。
(2)本发明的新型吲哚类化合物具有非常好的代谢稳定性和口服生物利用度,体内半衰期长,且对hERG抑制作用小(相关的心脏副作用小),因而具有很好的成药性。
(3)本发明的吲哚类化合物的合成路线设计巧妙、简便易行,原料便宜易得,合成工艺安全、环保,易于规模化生产。

化合物对FABP4和FABP5的抑制活性测试
实验原理与方法:游离的非共价荧光探针ANS与FABP4或FABP5结合后,导致ANS荧光强度增加和光谱蓝移。本实验通过测定ANS荧光信号值变化,评价化合物对FABP4和FABP5的抑制作用。FABP4和FABP5抑制活性测试用ANS底物竞争的方法,本申请在Kane和Bernlohr的方法的基础上做了相应的修改。带有His标签的人源FABP4或FABP5在BL21(DE3)菌株中表达,然后用Ni-NTASuperflow亲和层析树脂进行纯化得到蛋白。检测体系中的1,8-ANS底物的浓度为10μM,FABP4和FABP5蛋白的终浓度为10μM,再加入梯度浓度的化合物孵育3min,最后激发波长(EX)370nm/发射波长(EM)470nm检测荧光信号。根据荧光信号值计算受试化合物在不同浓度下对FABP4和FABP5的抑制率(%),并使用GraphPad Prism软件根据化合物浓度和抑制率拟合出其IC 50值。采用FABP4选择性抑制剂BMS309403、内源性FABP5配体亚油酸LA以及报道的FABP4/5双重抑制剂RO6806051作为阳性对照化合物。抑制率(%)根据下式进行:
抑制率(%)=[1-(F X-F 背景)/(F 0%-F 背景)]*100%
上式中F X表示在化合物X存在条件下,测定的体系的荧光值(fluorescence,F),F 背景表示体系仅有荧光底物ANS时的荧光值,F 0%表示抑制率为0%时,即不加化合物时体系的荧光值。

表6化合物67对hERG电流的抑制作用
Figure PCTCN2020093334-appb-000301
实验结果表明,阳性对照特非那定对hERG电流抑制作用具有浓度依赖性,其IC 50值为0.027μM。在本实验检测浓度范围内(0.3、1、3、10和30μM),化合物67对hERG电流抑制作用的IC 50值为24.74μM(n=2),表明该化合物对hERG抑制作用很小。本发明其他化合物效果类似,这提示本发明化合物对心脏的潜在副作用小。
