Description

一种取代的异吲哚啉-1,3-二酮类PDE4抑制剂及其药物用途
本申请要求2021年8月13日向中国国家知识产权局提交的,专利申请号为202110932229.9,发明名称为“一种取代的异吲哚啉-1,3-二酮类PDE4抑制剂及其药物用途”的在先申请的优先权。所述申请的全文通过引用的方式结合于本申请中。
技术领域
本发明属于医药领域,具体涉及一种取代的异吲哚啉-1,3-二酮类PDE4抑制剂、制备方法和药物用途。
背景技术
环腺苷酸(cAMP)作为第二信使在生物过程中起相当明显影响和作用。研究发现在哮喘、肺阻塞性病症、炎症等疾病中环腺苷酸的缺少或失活对这些疾病起推波助澜的作用(Lowe和Cheng,Drugs of the Future,17(9)期:799-807页,1992年),而炎性白细胞中环腺苷酸水平的提高对包括TNF-α和NF-κB的炎症介质的释放起抑制作用,同时环腺苷酸水平的提高还会导致呼吸道平滑肌的松弛作用。
而环腺苷酸失活的主要生物机制是由于环核苷酸磷酸二酯酶(PDE)家族破坏了环腺苷酸(Beavo和Reitsnyder,Trends in Pharm.,11期:150-155页,1990年)的水平。现已知道的就有11个PDE成员的家族酶,而抑制PDE4(PDE IV)型对环腺苷酸的提升和炎症介质的释放有明显效果(Verghes等,Journal of Pharmacology and Experimental Therapeutics,272(3)期:1313-1320页,1995年)。因此,选择性地抑制PDE4的有机化合物,有抑制呼吸道炎症,促进呼吸道平滑肌松弛以及治疗皮肤炎症的潜力。
抑制PDE4酶可阻断包括alpha-肿瘤坏死因子(TNF-α)的某些细胞因子的活性或生成。alpha-肿瘤坏死因子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。TNF-α能够促进例如分化、募集、增殖和蛋白质降解等大多数的细胞过程。在低水平下,TNF-α具有防止传染物、肿瘤和组织损伤的保护作用,但TNF-α在许多疾病中起诱导和加剧作用。当给哺乳动物或人TNF-α时就会引起或加重炎症、发烧、心血管作用、出血以及与急性感染和休克期出现的反应相类似的急性反应。
关节炎、类关节炎病症(例如骨关节炎和类风湿性关节炎)、肠炎(例如节段性回肠炎和溃疡性结肠炎)、脓毒病、银屑病(Psoriasis)、特异性皮炎(Atopic Dermatitis,AD)、接触性皮炎和慢性阻塞性肺病(COPD)、慢性肺炎、急性呼吸窘迫综合征(Acute Respiratory Distress Syndrome,ARDS)、白癜风(Vitiligo)、痒疹(Prurigo Nodularis)、外阴痛(Vulvodynia)、纤维变性疾病、恶病质、自身免疫疾病、类风湿性脊椎炎(Ankylosing Spondylitis)、骨质疏松症、节段性回肠炎、溃疡性结肠炎、肠炎、多发性硬化(Multiple Sclerosis,MS)、盘状红红斑狼疮(Discoid Lupus Erythematosus)、系统性红斑狼疮、辐射损伤、含氧量高的肺泡损伤(Tracey等,1987年,Nature,330期:662-664页和Hinshaw等,1990年,Circ.Shock,30期:279-292页(内毒素性休克);Millar等,1989年,Lancet,2期:712-714页和Ferrai-Baliviera等,1989年,Arch.Surg.,124期:1400-1405页(成人呼吸窘迫综合征);Bertolini等,1986年,Nature,319期:516-518页;Pignet等,1990年,Nature,344期:245-247页,Bissonnette等,1989年,Inflammation,13期:329-339页和Baughman等,1990年,J.Lab.Clin.Med.,115期:36-42页(慢性肺炎);Elliot等,1995年,Int.J.Pharmac.,17期:141-145页(类风湿性关节炎);Von Dullemen等,1995年,Gastroenterology,109期:129-135页(节段性回肠炎))等炎性疾病是普遍的疑难疾病,在这些炎症反应中,alpha-肿瘤坏死因子起关键作用。而对alpha-肿瘤坏死因子的抑制在炎性疾病动物模型中可以看出有效地阻断慢性和急性的炎症反应。
已经发现许多小分子抑制剂能够治疗涉及alpha-肿瘤坏死因子的炎性疾病(参见Lowe的综述,1998年,Exp.Opin.Ther.Patents,8期:1309-1332页)。这一类分子是美国专利US6020358、US6962940,以及WO0134606A1,WO0025777,WO2012083153、WO2018157779A1、WO0134604、WO2012083153、WO20 号描述的取代的苯乙基砜类化合物。在专利US2003187052中公开了阿普斯特,同族中国专利为CN1652772、CN1965823、CN101683334、CN03811093.8。
但现有技术的异吲哚啉-1,3-二酮类的PDE4抑制剂的生物活性比较一般,药效不高,因此需要提供药效良好,具有新颖结构的异吲哚啉-1,3-二酮类PDE4抑制剂。
