本申请是申请日为2013年8月28日,申请号为201380044856.2,发明名称为“氨磺酰基-芳基酰胺和其作为药物用于治疗乙型肝炎的用途”的发明专利申请的分案申请。
技术背景
乙型肝炎病毒(HBV)是一种有包膜的、部分双链DNA(dsDNA)的、嗜肝病毒DNA家族(肝病毒科(Hepadnaviridae))的病毒。它的基因组包含4个重叠阅读框:前核/核基因;聚合酶基因;L、M和S基因(它们编码三个包膜蛋白质);以及X基因。
在感染前时,该部分双链DNA基因组在宿主细胞核中(开环DNA;rcDNA)转变为共价闭合环状DNA(cccDNA)并且该病毒mRNA进行转录。一旦被壳体化,该前基因组RNA(pgRNA)(其还为核心蛋白和Pol编码)作为模板用于逆转录,这种逆转录在核衣壳中再生该部分dsDNA基因组(rcDNA)。
HBV在亚洲和非洲的部分地区造成了流行病,并且它在中国是地方性的。HBV已经在全球感染了大约20亿人,其中大约3.5亿人发展成了慢性传染病。该病毒造成了乙型肝炎疾病并且慢性传染病与肝硬化和肝癌的发展的高增加风险相关联。
乙型肝炎病毒的传播来源于暴露于传染性的血液或体液,同时在血清中具有高效价DNA的慢性携带者的唾液、泪液以及尿液中检测到了病毒DNA。
存在一种有效的并且具有良好耐受性的疫苗,但是直接治疗的选择目前还限于干扰素以及以下的抗病毒药;替诺福韦、拉米夫定、阿德福韦、恩替卡韦以及替比夫定。
此外,杂芳基二氢嘧啶(HAPs)在组织培养以及动物模型中被鉴别作为的一类HBV抑制剂(韦伯(Weber)等人,《抗病毒研究》(Antiviral Res.)54:69-78)。
WO 2013/006394(公开于2013年1月10日),和WO 2013/096744(公开于2013年6月27日),涉及抗HBV活性的氨磺酰基-芳基酰胺。
在这些直接的HBV抗病毒药的问题中可能遇到的是毒性、致突变性、缺乏选择性、疗效差、生物利用度差以及合成困难。
针对另外的HBV抑制剂有一种需要,该抑制剂可以克服至少一种这些不利条件或者该抑制剂具有另外的优势,例如增加的效价或者一种增加的安全窗。

表2
或其一种药学上可接受的盐或溶剂化物
在一个另外的方面,本发明关注一种药物组合物,该药物组合物包括如在此指定的治疗上或预防上有效量的具有化学式(I)的化合物,以及药学上可接受的载体。在这种背景下,一种预防上的有效量是一种在有被感染风险的受试者中足以预防HBV感染的量。在这种背景下,一种治疗上的有效量是一种在已被感染的受试者中足以稳定HBV感染、减轻HBV感染、或根除HBV感染的量。仍然在一个另外的方面,本发明涉及制备如在此指定的药物组合物的方法,其包括紧密地将药学上可接受的载体与如在此指定的治疗上有效量的或预防上有效量的具有化学式(I)的化合物混合。
因此,可以将本发明的化合物或其任何亚组配制为用于给药目的的不同的药用形式。可以引用所有通常用于全身给药药物的组合物作为合适的组合物。为了制备本发明的药用组合物,将作为活性成分的有效量的特定化合物(可任选地处于加成盐形式)与药学上可接受的载体以紧密混合进行组合,该载体可以取决于用于给药的所希望的制品形式而采取各种各样的形式。令人希望的是这些药用组合物处于特别适合用于经口服、直肠、经皮、或肠胃外注射给药的单元剂型。例如,在制备处于口服剂型的药物组合物中,可使用任何常见药物介质,在口服液体制剂(例如悬浮剂、糖浆剂、酏剂、乳液以及溶液)的情况中,例如像水,二醇类、油类、醇类以及类似物;或者在粉剂、丸剂、胶囊剂以及片剂的情况中的固体载体,例如淀粉、糖、高岭土、润滑剂、粘合剂、崩解剂以及类似物。因为它们易于给药,片剂和胶囊代表最有利的口服单位剂型,在这种情况中采用固体药物载体。对于肠胃外组合物,载体通常至少大部分包括无菌水,虽然可以包括例如帮助溶解的其他成分。可以制备例如可注射溶液,其中载体包括生理盐水溶液、葡萄糖溶液或生理盐水与葡萄糖溶液的混合物。也可以制备注射混悬液,在此情况下可以采用合适的液体载体、悬浮剂以及类似物。还包括预期在使用之前不久将其转化为液体形式制品的固体形式制品。在适用于经皮给药的组合物中,载体可任选地包括渗透增强剂和/或适合的润湿剂,可任选地与占较小比例的具有任何性质的适合的添加剂组合,这些添加剂不对皮肤引入显著的有毒作用。本发明的化合物还可以按溶液、混悬液或干粉形式,使用任何本领域已知的递送系统经由口腔吸入或吹入来给予。
尤其有利的是配制处于单位剂型的前述的药用组合物,以便于给药和剂量的一致性。如在此使用的单位剂型指的是适合作为单位剂量的物理离散单位,各单位含有预定量的活性成分,该预定量的活性成分经计算与所需药物载体相结合而产生所希望的治疗效果。此类单位剂型的实例是片剂(包括刻痕片剂或包衣片剂)、胶囊、丸剂、栓剂、粉剂包、晶片、可注射的溶液或悬浮剂以及类似物、以及它们的隔离的多重体。
具有化学式(I)的化合物作为HBV复制循环的抑制剂是有活性的并且可以用于治疗和预防HBV感染或与HBV相关的疾病。后者包括进展性肝纤维化、导致肝硬化的炎症和坏死、末期肝病、以及肝癌。
由于它们的抗病毒特性,特别是它们抗-HBV特性,具有化学式(I)的化合物或其任何亚组在HBV复制循环的抑制中是有用的,具体地在感染HBV的温血动物的治疗中(具体地人类)以及用于HBV感染的预防方面是有用的。此外本发明涉及治疗被HBV感染或处于被HBV感染的风险的温血动物(具体地人类)的方法,所述方法包括给予治疗上有效量的具有化学式(I)的化合物。
如在此指定的具有化学式(I)的化合物,可以因此被作为一种药物,具体地作为治疗或预防HBV感染的药物。作为药物的所述用途或治疗方法包括将有效对抗HBV感染相关病症的量或有效预防HBV感染的量全身性给药至HBV感染的受试者或易受HBV感染的受试者。
本发明还涉及本发明的化合物在制造用于治疗或预防HBV感染的药剂中的用途。
总体上,考虑的是抗病毒有效的日量将是从约0.01mg/kg至约50mg/kg体重,或从约0.01mg/kg至约30mg/kg体重。可以合适的是将所要求的剂量以在全天中的合适的间隔作为两个、三个、四个或更多个亚剂量给予。所述亚剂量可以配制为单位剂型,例如每单位剂型含有约1mg至约500mg、或约1mg至约300mg、或约1mg至约100mg、或约2mg至约50mg的活性成分。
本发明还关注如在此指定的具有化学式(I)的化合物或其任何亚组与抗-HBV制剂的组合。术语“组合”还涉及一种产品或试剂盒,该产品和试剂盒包含(a)如以上指定的具有化学式(I)的化合物,以及(b)至少一种能够治疗HBV感染的其他的化合物(在此指作为抗-HBV剂),作为用于同时、分开或顺序地用于HBV感染治疗的组合制剂。在一个实施例中,本发明关注具有化学式(I)的化合物或其任何亚组与至少一种抗-HBV剂的组合。在一个具体实施例中,本发明关注具有化学式(I)的化合物或其任何亚组与至少两种抗-HBV剂的组合。在一个具体实施例中,本发明关注具有化学式(I)的化合物或其任何亚组与至少三种抗-HBV剂的组合。在一个具体实施例中,本发明关注具有化学式(I)的化合物或其任何亚组与至少四种抗-HBV剂的组合。
预先已知的抗-HBV剂的组合(例如干扰素-α(IFN-α)、聚乙二醇化干扰素-α、3TC、阿德福韦或其组合)以及具有化学式(I)的化合物或其任何亚组可以在组合疗法中用作一种药物。
通用合成:
根据化学式(I)的化合物可以如在通用方案1至7中所描述的进行合成。
一种具有通式II的羧酸氯可以选择性地例如在有机溶剂(像CH2Cl2)中,在有机碱(像三乙胺或DIPEA(N,N-二异丙基乙胺))存在下与具有通式III的苯胺反应,或者作为另一个实例,通过将苯胺III添加至化合物II的回流甲苯溶液,产生化合物IV。化合物IV中的残余的磺酰氯官能度可以进一步与具有通式V的胺进行反应,产生具有化学式(I)的化合物。可替代地,具有通式(I)的化合物可以如在方案2中所描述的获得。这次例如在有机溶剂中(像CH2Cl2)在有机碱(像三乙胺或DIPEA)的存在下,或者作为另一个实例,在Na2CO3的存在下在H2O/THF的混合物中,磺酰氯VI与具有通式V的胺进行反应。在一种活化试剂(像例如HATU)和一种有机碱(像三乙胺或DIPEA)存在下,将形成的化合物VII与具有通式III的苯胺进行偶联。
方案1
方案2
具有化学式IX和X的化合物的通用合成描述在方案3中。中间体IV与氨进行反应,产生具有化学式VIII的化合物。在CHCl3的回流中在SiO2和H2SO4的存在下,这个中间体可以通过与碳酰氯(例如环己烷碳酰氯)反应进一步转化为具有化学式IX的化合物。具有通式IX的化合物可以进一步转化为具有化学式X的化合物。在R1等于Me的情况下,这可以通过在MeOH/CH2Cl2中IX与TMSCHN2反应来完成
方案3
在另一个实例中,在一种碱(像NaOH)存在下,化合物IV可以与氨基酸XI反应,产生如在方案4中描述的化合物XII。然后这个中间体XII可以可任选地环化为化合物XIII,例如通过在甲苯中将乙酸酐与KOAc进行加热,或者在碱(像三乙胺)存在下将羧酸转变为酰基氯接着环化。具有结构XI的氨基酸的合适的实例是具有5-氨基戊酸或4-氨基丁酸的衍生物
方案4
方案5
具有通式XVI的化合物的合成途径描述在方案5中所。在THF中,通过用二氮烯-1,2-二羧酸二乙酯和PPh3进行处理,氨基乙醇衍生物XIV(如在方案1中针对具有通式(I)的化合物所描述的制备)被转化为氮丙啶衍生物XV。具有通式XV的氮丙啶与亲核体Nu进行反应,产生具有通式XVI的化合物。此类亲核体(Nu)的实例是,但不限于吗啉和1-甲基哌嗪。根据在方案5中描述的途径而合成的化合物的实例是化合物116和117。
方案6
一种用于具有通式VII的化合物的合成的可替代的方法是如在方案6中描述的经由酯XVII。将XVII与胺V进行反应(例如在有机溶剂(像CH2Cl2或THF)中在有机碱(像例如三乙胺或DIPEA)存在下,接着将该酯进行水解(例如用在THF/H2O中的LiOH),接着进行酸化,产生具有通式VII的化合物。具有通式VII的化合物(经由方案2或方案6中的途径获得),可以转化为具有化学式XIX的酰基氯(例如通过用草酰氯或亚硫酰二氯进行处理)。然后具有通式XIX的化合物可以通过与具有通式III的苯胺进行反应转化为具有通式(I)的化合物。
具有通式VI的化合物可以例如通过在CH2Cl2中使用草酰氯进行处理转变为具有通式II的化合物。
方案7
针对具有通式XVII或VI的化合物的可能合成途径描述于方案7中,并且在实验部分进一步举例说明。羧酸XXI或羧酸酯XX的氯磺化可以分别产生具有通式VI或XVII的化合物,例如通过使用氯磺酸进行处理(例如在《磷、硫以及硅和相关元素》(Phosphorus,Sulfur,and Silicon and the Related Elements)56卷,Iss.1-4,1991中所综述的)。可替代地,具有通式XXV或XXIV的化合物可以分别转变为具有通式XVII和VI的化合物,这是通过转变为相应的重氮盐(例如通过NaNO2/HCl),接着将该重氮盐转变为磺酰氯(例如通过SO2/CuCl)(例如如在《有机方法研究&进展》(Organic Process Research&Development)13(5),875-879;2009中描述的)。可替代地,具有通式XXII和XXIII的化合物(其中R7等于H、苄基或甲基)可以分别转变为具有通式XVII和VI的化合物,例如通过在AcOH/H2O中用Cl2或N-氯代琥珀酰亚胺进行处理。
在这个通用合成部分中由R4代表的取代基是指包括本领域的普通技术人员没有额外负担下适合用于转变为根据本发明的任何R4取代基的任何取代基或反应性组分。
在以下化合物合成部分中没有特别描述的化合物可以根据以上方案1-7进行合成以及商购获得。
