  • the main circulating variant viruses since December 2020 include the following 4 types: the virus variant named B.1.1.7 (Alpha) discovered in the UK in December 2020, and the highly virulent SARS-CoV discovered in South Africa in December 2020 -2 variant B.1.351 (Beta), P.1 (Gamma) virus discovered in Brazil in January 2021, and B.1.617.2 (Delta) variant virus strain that first broke out in India in April 2021.
  • the three important mutations of the Delta variant strain - L452R, T478K and P681R improve the affinity between the new coronavirus S protein and the receptor, and increase the virus's infectivity.
  • Clinical data show that the Delta variant, characterized by a shorter incubation period, faster spread, and increased infectivity, has rapidly become a major infectious agent in some regions.
  • the Delta strain is also the virus strain that has caused outbreaks in Guangzhou and Nanjing since May 2021. According to the report of the US Centers for Disease Control and Prevention, the basic infection number R0 of the Delta mutant virus has reached 8-9.
  • the Delta strain resulted in reduced vaccine protection against infection with COVID-19 and reduced efficacy of neutralizing antibody drugs.
  • the novel coronavirus is a positive-sense single-stranded RNA virus with a methylated cap at the 5' end and a polyadenylation tail at the 3' end.
  • the novel coronavirus genome consists of at least 10 open reading frames (ORFs) and some regulatory genes, encoding structural proteins (nucleocapsid protein N, transmembrane protein M, envelope protein E and spike protein S) and Nonstructural proteins (chymotrypsin-like protease 3CLpro or Mpro, papain-like protease PLpro, helicase, RNA-dependent RNA polymerase (RdRp)), which are key enzymes in the viral life cycle.

Description

一种核苷类化合物及其用途
本申请要求中国专利申请号:202011613943.3,申请日期2020年12月30日,中国专利申请号:202110562244.9,申请日期2021年5月21日的优先权,通过引用将其并入本文。
技术领域
本发明属于药物合成领域,涉及药学技术和病毒感染疾病技术领域。具体涉及一种核苷类化合物及其衍生物、前药和/或其药学上可接受的盐,及其制备方法与用途。
背景技术
[根据细则26改正07.01.2022] 
2019新型冠状病毒(2019 Novel Coronavirus,2019-nCoV,新冠病毒),又名严重急性呼吸综合征冠状病毒2(Severe Acute Respiratory Syndrome Coronavirus 2,SARS-CoV-2)。新冠病毒引起的全球新冠肺炎(COVID-19)大流行已经导致超过2亿人感染,数百万人死亡。新冠病毒的潜伏期长、传染性强,这为病例的筛查和控制带来了极大困难。
此次新冠病毒疫情与2003年的非典型肺炎(SARS)和2012年的中东呼吸综合征(MERS)疫情相比,传染速度快,感染面积大,表现出高度变异的的能力,出现长期与人类共存的发展趋势。2020年12月以来主要流行的变异病毒包括以下4种:2020年12月爆发的英国发现名为B.1.1.7(Alpha)的病毒变种、2020年12月在南非发现的高毒性SARS-CoV-2变种B.1.351(Beta)、2021年1月巴西发现的P.1(Gamma)病毒和2021年4月在印度首次爆发的B.1.617.2(Delta)变异病毒株。Delta变异株具备的3个重要突变——L452R、T478K和P681R,提高了新冠病毒S蛋白与受体之间的亲和性,增加病毒的传染能力。临床数据显示出Delta变异株潜伏期变短、传播速度变快,以及感染力增强等特征,在某些地区已迅速成为主要的传染病原体。Delta毒株也是2021年5月以来先后引起广州、南京疫情的病毒株。美国疾病控制与预防中心的报告指出,Delta突变病毒的基本传染数R0已达到8-9。Delta毒株导致疫苗预防感染COVID-19保护力降低,降低了中和抗体药物的疗效。近期,于南非又发现了一种新型变异毒株B.1.1.529(Omicron毒株),其刺突蛋白上有32个突变,比Delta毒株多一倍。多个突变可能会增强毒株的传染性、致病性、免疫逃逸能力以及对疫苗的破防能力。例如,礼来公司研发的抗体药物Bamlanivimab单药用于SARS-CoV-2变异病毒时,会产生耐药性;bamlanivimab和etesevimab双抗体疗法对Beta和Gamma变异病毒的中和能力有限。美国FDA已经撤销了对bamlanivimab的紧急使用授权。而靶向病毒复制过程中关键蛋白的小分子抑制剂具有更广谱的效果,迫切需要开发对变异病毒有效的广谱小分子抗新冠药物。
新型冠状病毒是一种正义单链RNA病毒,具有5’端的甲基化帽子和3’端的聚腺苷酸尾部。新冠病毒基因组由至少10个开放阅读框架(open reading frame,ORF)和一些调节基因组成,分别编码结构蛋白(核衣壳蛋白N、跨膜蛋白M、包膜蛋白E和刺突蛋白S)和非结构蛋白(糜蛋白酶样蛋白酶3CLpro或Mpro、木瓜样蛋白酶PLpro、解旋酶、RNA依赖的RNA聚合酶(RdRp)),这几种非结构蛋白是病毒生命周期中的关键酶。冠状病毒侵入机体并在靶细胞中复制过程包含吸附 结合、融合进入、遗传物质脱壳、生物合成、装配释放等程序。病毒感染机体后一方面影响细胞正常功能,引发细胞凋亡直接破坏组织器官;另一方面,机体产生异常的天然免疫应答,引起细胞因子风暴,导致肺部巨噬细胞和中性粒细胞大量浸润,同时导致心、肝、肾组织损伤和休克。
针对病毒生命周期涉及的关键蛋白和酶,国内外研究机构采用“老药新用”策略筛选到一些药物并推进COVID-19临床研究,一些核苷类抗病毒“老药”如索菲布韦(Sofosbuvir)、Galidesvir、法匹拉韦(Favipiravir)、利巴韦林(Ribavirin)、阿兹夫定(Azvudine)等针对COVID-19的治疗也相继开展了临床研究,但由于这些药物对新冠病毒的抑制活性较弱或者毒性较大,疗效有限。
在病毒蛋白中,RdRp被认为是最具战略意义的药物靶标。病毒聚合酶的结构同源性,特别是冠状病毒科其他成员的结构同源性高,如新冠病毒与SARS相似性达96%,是广谱的抗病毒药物靶点。大多数病毒感染治疗方法都会包含至少一种聚合酶抑制剂。靶向RdRp的注射药物瑞德西韦(Remdesivir)于2020年10月上市,是首个抗新冠小分子新药,尽管瑞德西韦表现出积极的治疗效果,但瑞德西韦的磷酰胺的前药部分在体内极易水解,半衰期只有1h,药物有效作用时间短,作为注射用药,仅供住院的重症病人使用,大大限制了药物的可及性和适用人群。而口服抗新冠小分子药物可以用于预防或者治疗治疗轻症到重症各类感染者,减少感染的重症和住院患者的比例,并有效控制新冠病毒传播,比注射药物有明显优势。
通过申请人前期对瑞德西韦及其前提化合物GS-441524的研究(Li,et al.,J.Med.Chem.2020),发现GS-441524在小鼠体内的活性测试中产生了优于瑞德西韦的抗病毒作用。化合物GS-441524虽然与瑞德西韦的作用机理类似,但其显示了更好的安全性。因此,申请人已申请了描述化合物GS-441524在预防、缓解和/或治疗SARS-CoV-2的药物的应用专利(申请号或专利号202011000517.2)。
后期通过对GS-441524进行药代动力学分析,发现其生物口服利用度很低,只能以注射液形式使用。因此,寻求GS-441524的可口服的低毒性核苷衍生物或前药研究将具有重大意义。为了提高GS-441524的PK性质,通过在核苷的羟基上引入酯型前药设计合成了一系列前药。这类前药主要目的为了使GS-441524的血浆稳定性提高,从而增加药物血浆暴露量,一方面创造性地引入一些带位阻的酯型前药,以防药物在血浆中提前水解而到达不了靶细胞;另一方面,引入长链脂肪酸以期提高血浆稳定性,从而减少药物摄入次数和摄入量,最终在达到治疗效果的同时减少毒副作用。除此之外,GS-441524在水溶液和有机溶剂中的溶解度极低,所涉及的前药能有效的改善化合物的理化性质,包括水溶性,Clog P等。

药物制剂
本发明所述化合物用常规载体和赋形剂配制,它们将按照常规实践进行选择。尽管能够将活性成分单独施用,但是优选将它们制成药物制剂。本发明的制剂,无论是用于兽类还是人类应用,均包含至少一种如上定义的活性成分与用于其的一种或多种可接受的载体,且任选包含其它治疗成分,尤其是如本文公开的那些另外的治疗成分。载体必须是“可接受的”,其含义是与制剂中的其它组分相容,并且在生理上对其接受者而言无害。
制剂包括适合于上述施用途径的那些。可以将制剂便利地制成单位剂型,并且可以通过制药领域众所周知的任意方法制成制剂。技术和制剂一般可以在Remington′s Pharmaceutical Scicnces(Mack Publishing Co.,Easton,PA.)中找到。这类方法包括将活性成分与构成一种或多种辅助组分的载体混合的步骤。一般而言,如下制备制剂:通过均匀和紧密混合活性成分与液体载体或细分散固体载体或它们两者,且然后如果需要,使产物成形。
本发明进一步提供了兽用组合物,其包含至少一种如上定义的活性成分与用于此的兽用载体。
兽用载体为用于兽用组合物目的物质并且可以为固体、液体或气态物质,另外其为惰性的或兽药领域中可接受的且与活性成分相容。可以通过口服、肠胃外或通过任意其它所需途径施用这些兽用组合物。
施用途径:
本发明的一种或多种化合物(本文称为活性成分)通过适合于受治疗的病况的任何途径施用。合适的途径包括口服、直肠、鼻、肺、局部(包括口腔和舌下)和胃肠外(包括皮下、肌内、静脉内、皮内、鞘内和硬膜外)等。应当理解,优选的途径可随着例如接受者的病况而变化。
本发明化合物的代谢产物:
本文所述化合物的体内代谢产物(不包括GS-441524)也落在本发明的范围之内,其程度是,这样的产物相对于现有技术是新颖的且非显而易见的。这些产物可产生自,例如,施用的化合物的氧化、还原、水解、酰胺化、酯化等,主要是由于酶过程。因此,本发明包括通过以下方法生产的新颖的且非显而易见的化合物,该方法包括,使本发明化合物与哺乳动物接触足够产生其代谢产物的一段时间。此类产物典型如下鉴定:制备放射标记(例如 14C或 3H)的本发明化合物,将它以可检测的剂量(例如大于约0.5mg/kg)肠胃外地施用给动物,例如大鼠、小鼠、豚鼠、猴或人,允许发生代谢的足够时间(典型地,约30秒到30小时),并从尿、血或其它生物样品中分离它的转化产物。由于它们被标记,这些产物很容易分离(其它是使用能结合残留在代谢产物中的表位的抗体来分离)。代谢产物的结构以常规方式测定,例如用MS或NMR分析。一般而言,代谢产物的分析以与本领域技术人员公知的常规药物代谢研究相同的方法进行。转化产物,条件是它们不以其它方式在体内被发现,即使它们自身不具有新冠病毒聚合酶抑制活性,也可用于本发明化合物的治疗给药的诊断测定。
用于测定化合物在替代胃肠分泌物中的稳定性的配方和方法是已知的。在本文中将化合物定义为在胃肠道中是稳定的,其中在37℃温育1小时后,少于约50摩尔百分比的受保护基团在肠或胃液的替代物中脱保护。不能仅仅因为化合物对胃肠道是稳定的,就认为它们在体内不会水解。本发明的前药典型地在消化系统中是稳定的,但是它们通常在消化腔、肝脏或其它代谢器官中或在细胞内基本上水解为母体药物。
另外需要指出,所述具有式I结构的化合物、其前药和/或其药学上可接受的盐类药物针对不同患者的特定使用剂量和使用方法决定于诸多因素,包括患者的年龄,体重,性别,自然健康状况,营养状况,药物的活性强度,服用时间,代谢速率,病症的严重程度以及诊治医师的主观判断。活性成分的有效剂量至少取决于要治疗病症的性质、毒性(不管化合物是预防使用还是抵抗活性病毒感染)、递送的方法和药物制剂,且将通过临床医生使用常规剂量递增研究而决定。可以预期剂量为每天约0.0001到约200mg/kg体重;典型地,每天约0.01到约50mg/kg体重;更典型地,每天约0.1到约50mg/kg体重;最典型地,每天约0.5到约30mg/kg体重。例如,对于约70kg体重的成年人来说,每日候选剂量将在35mg到2100mg的范围内,优选为5mg到500mg,且可采取单剂量或多剂量的形式。
上述各种剂型的药物均可以按照药学领域的常规方法制备。

结论:测试化合物在HEK293T细胞中均不同程度地抑制SARS-CoV-2的复制。对于环状酯前药,其中ATV2001-ATV2007及ATV2089等在10μM的浓度下对SARS-CoV-2复制子的抑制活性均超过90%,活性良好。而含有氮杂原子的前药活性稍差,例如N-甲基哌啶-4-甲酸酯的化合物ATV2088在10μM浓度下的抑制对复制子的抑制活性为在50%~80%之间(为55.07%),活性稍弱。长链脂肪酸酯的化合物均有较好活性,例如,十五烷酸酯(ATV2088)和十六烷酸酯在 10μM的抑制率分别为92%和95%。
实例27:化合物的人血浆中稳定性测试
冻存的血浆直接置于室温的水中融化,然后进行离心(3,220g,10分钟),离心后取出表面的杂质和块状沉淀。配制待测药和对照药溴丙胺肽林的1mM DMSO工作液,然后取4μL工作液加入到796μL人源血浆中,使其终浓度为5μM,。5μM的加药血浆在37℃水浴中以大约60rpm的转速进行孵育。实验为双平行。在每个指定的时间点(包括0、15、30、60和120分钟)取出对应离心管,随后加入6倍体积的淬灭剂(含内标乙腈(内标,500nM拉贝洛尔,100nM阿普唑仑和2μM酮洛芬))。涡旋2分钟,在20,000g条件下离心15分钟沉淀蛋白。转移100μL上清液至新板中。根据待测物的液质响应信号和峰形,可能用100μL或200μL水对上清液进行稀释。混匀,利用液质进行样品分析。
液相部分为Shimadzu 30AD,Triple QuadTM 5500型电喷雾质谱。色谱柱:Thermo Accucore C18 2.5μ(50×2.1mm)流动相:A,水(0.1%甲酸);B,乙腈(0.1%甲酸)梯度洗脱。通过AB公司的Analyst 1.6.2软件进行系统控制及数据处理,结果如表3所示。
表3:化合物人血浆半衰期测试结果
编号 人血浆半衰期(min)
ATV006 <5min
Propantheline 27.36
ATV2001 31.93
ATV2002 15.69
ATV2003 >120
ATV2004 5.80
ATV2005 33.33
ATV2006 199.48
ATV2007 >120
ATV2088 >120
ATV2089 >120
结论:人血浆稳定性的实验采用propantheline作为阳参化合物,Propantheline的血浆半衰期为27.36min。ATV006是5`-异丁酯取代的GS-441524前药,血浆稳定性差,半衰期小于5min。本专利的化合物均不同程度提高了化合物的血浆稳定性,除ATV2004外,半衰期均大于15min。其中化合物ATV2088、ATV2089、ATV2003、ATV2007极大地提高了稳定性,半衰期大于2h。核苷类化合物由于含有多个极性大的羟基基团,膜穿透性较差。本专利所发明的化合物采用位阻大的有机酸与核苷的5`-OH形成酯键,大位阻的基团降低了血浆中酯酶对化合物的水解速率,提高了化合物的血浆稳定性,有望改善药代动力学性质、改善药物的组织分布,靶向药物到特定的病变部位,延长作用时间,从而提高抗病毒效果。
