Description
本申请是以CN申请号为201910346258.X,申请日为2019年4月26日的申请为基础,并主张其优先权,该CN申请的公开内容在此作为整体引入本申请中。
本申请属于医药技术领域,具体涉及9-[3-(6-氨基)-吡啶基]-1-[(3-三氟甲基)-苯基]苯并[h][1,6]萘啶-2(1H)-酮(式I)、其立体异构体、其药物上可接受的盐和/或两者溶剂化物和/或水合物,及含上述化合物的药物组合物,用于广谱抗病毒方面的用途,特别是在治疗肠道病毒感染性疾病中的应用。
肠道病毒(Enterovirus)属于小RNA病毒科(Picornaviridae)肠道病毒属,是一种无包膜的单股正链RNA病毒,主要包括脊髓灰质炎病毒、柯萨奇病毒A组、柯萨奇病毒B组、埃可病毒及新肠道病毒等,其中柯萨奇病毒和新肠道病毒是手足口病的主要病原体。肠道病毒感染后可以导致脊髓灰质炎样的严重的神经系统并发症,是手足口病重症病例和死亡病例的主要原因。手足口病主要流行于亚太地区,包括台湾,新加坡和越南在内的许多国家都有较大规模的流行。最近几年,手足口病在我国大陆持续爆发流行,重症病例和死亡病例逐年增加,已经成为严重威胁我国儿童健康和社会稳定的公共卫生问题,受到社会各界的高度关注。一般来说,疫苗是对抗病毒性传染病的重要手段,但是手足口病一般是由多种肠道病毒感染所致,且一种疫苗只能对一种肠道病毒发挥作用对别的种类没有交叉保护效果。
近年来流感频繁爆发,严重危害人类和动物生命健康。2003年底爆发的高致病性禽流感,不仅造成全球数千万家禽、野禽死亡,而且导致250余人感染死亡,死亡率高达60%。2009年4月源于北美的新型甲流很快席卷全球,并导致万余人死亡。尽管人类对流感的认识已有近百年历史,但现有防治流感(特别是高致病性流感)的医药技术仍十分薄弱。可用于流感防治的药物品种很少,主要有M2离子通道抑制剂金刚烷胺和金刚乙胺、神经氨酸 酶抑制剂奥司米韦(俗称“达菲”)和扎那米韦及广谱抗病毒药利巴韦林三类药物。金刚烷胺临床上应用了多年,多种亚型流感毒株对其已产生严重的耐药性,而达菲价格昂贵,且病毒对其耐药性的报道也日渐增多。
人鼻病毒(HRV)属于小RNA病毒科,是一组单链小分子RNA病毒,至今已发现有100多种血清型。HRV是人类普通感冒的主要致病因素,急慢性支气管炎和其他呼吸道疾病也与之有关。尽管鼻病毒的感染是自限性的,但是病人会发生诸如哮喘、充血性心力衰竭、支气管扩张、包囊纤维化等并发症。特别是对于儿童和有基础疾病的人群,HRV感染会导致严重的后遗症。由于HRV有众多血清型,所以通过接种疫苗的方式来预防HRV感染,在理论上缺乏可行性。曾经认为干扰素(IFN)可作为控制HRV及其他核糖核酸病毒感染的主要物质,但是IFN治疗对已形成的HRV感染无效。
疱疹病毒家族是一类具有包膜结构的双链DNA病毒,单纯疱疹病毒(herpes simplex virus,HSV)属α亚科,广泛存在于自然界中,能感染人和许多动物,尤其对人体皮肤组织具有较强的嗜性。疱疹病毒主要通过皮肤、黏膜和神经组织感染宿主而引起相应的病变,是人类病毒性疾病的常见病原体。单纯疱疹病毒可分为HSV-1及HSV-2两种血清型,HSV-1感染人体后主要引起口唇疱疹、咽炎、角膜炎,也能引起散发性脑炎等严重疾病的发生。HSV-2主要通过破损皮肤及黏膜感染引起生殖器疱疹,近年来的流行病学调查发现,在引起生殖器疱疹病毒的病原中,HSV-1与HSV-2占有同样重要的地位,均可在体内长期潜伏。在潜伏感染过程中,疱疹病毒基因组的结构和功能均未受到任何影响和破坏,而病毒基因转录及表达相关的一系列调控都处于停滞状态。此过程没有完整的基因组复制,但存在有限的局部基因转录,并在特定条件下进入增殖性复制感染阶段。目前生殖器疱疹发病率迅速增加且易复发,这给相关疾病的治疗及预防造成了巨大困难。
水泡性口炎病毒(Vesicular stomatitis virus,VSV)可以引起水泡性口炎,是一类高度接触性的人畜共患传染病的病原体,发病后的临床症状与口蹄疫、猪水疱病及猪水疱疹病等疾病非常相似,通常情况下很难进行区分。以唇、蹄冠部和乳房等部位出现小囊泡、溃疡和结痂等为主要临床特征。由糜烂及溃疡引起的疼痛造成动物的食欲减退及继发性乳腺炎从而导致动物的生产力降低甚至死亡,给养殖业造成严重的经济损失。同时,VSV也可以感染人类,引发类似流感的症状,严重的导致死亡。
综上所述,研发一种具有特异性的小分子广谱抗病毒药物迫在眉睫。Torin类化合物是一种ATP类似物,该化合物是一种丝/苏氨酸蛋白激酶,又称蛋白激酶B,是mTOR/AKT信号通路的重要因子,在细胞的增生、分化、凋亡和代谢等一系列生理活动中起着重要作用,与肿瘤的发生息息相关。目前该化合物已经进行了临床前实验。
上文涉及的手足口病(hand,foot and mouth disease,HFMD)是一种由多种人类肠道病毒引起的儿童传染病,并经粪-口或呼吸道飞沫传播,亦可经接触患者皮肤、黏膜疱疹液 而发生感染。引发手足口病的病毒属于人类肠道病毒属(human enterovirus,HEV),按血清型分类可分为HEV-A、HEV-B、HEV-C和HEV-D四种亚型,其中以肠道病毒71型(Enterovirus71,EV71)和柯萨奇病毒A组16型(Cox Asckievirus16,CA16)最为常见。近半个世纪以来,全球多地多次出现手足口病疫情,遍及各大洲,使其成为备受关注的世界性疾病。20世纪90年代,亚洲迎来了手足口病爆发的高峰,尤其在东南亚地区,以EV71感染为主的手足口病大规模流行,并引发中枢神经系统症状,导致死亡病例大量增加。
目前,尚无能够有效抑制肠道病毒的特效抗病毒药物上市,现阶段处于临床前研究的抗肠道病毒药物主要有以下几类:1)靶向病毒吸附和进入阶段的抗病毒药物,例如可溶性清道夫受体B2(human scavenger receptor class B,member 2,SCARB2)、P-选择素糖蛋白配体-1(P-selectin glycoprotein ligand-1,PSGL-1)、肝素或肝素类似物和唾液酸等;2)靶向病毒脱壳阶段的抗病毒药物,如脱壳抑制剂WIN51711、BPROZ-194、BPROZ-112等;3)靶向病毒RNA翻译阶段的抗病毒药物,如奎纳克林、金刚烷胺等;4)靶向病毒蛋白质加工阶段的抗病毒药物,如2A蛋白酶底物类似物LVLQTM和3C蛋白不可逆肽酶抑制剂AG7088等;但其大多作用于单个病毒亚型,不具有广谱学特性,且由于肠道病毒的高度变异性,以病毒自身为靶点的抗病毒药物极易产生耐药性。此外,一些抗肠道病毒的疫苗也在研发之中,如重组VP1蛋白疫苗和重组DNA疫苗,但由于应用时间较短、应用规模较低,目前尚缺乏充足的临床反馈。
