Description
相关发明的交叉引用
本申请要求序列号为62/189,975(2015年7月8日提交)的美国临时申请的优先权。
本发明的领域
本发明涉及化合物、组合物和治疗人类免疫缺陷性病毒(HIV)感染的方法。更具体地说,本发明提供了新的HIV的抑制剂、含有这种化合物的药物组合物和使用这些化合物来治疗HIV感染的方法。本发明还涉及制备下文所描述的化合物的方法。
发明背景
人类免疫缺陷性病毒(HIV)已经被确定为获得性免疫缺损综合征(AIDS)的病原体,AIDS是不治之症,其特征在于:免疫系统遭到破坏,并且不能抗击危及生命的机会感染。近来的统计表明,在世界范围内,大约三千五百三十万人感染了该病毒(UNAIDS∶Report onthe Global HIV/AIDS Epidemic,2013)。除了已经感染大量个体之外,该病毒还在继续扩散。据估计,从2013年开始,在这一年之中,新的感染接近三百四十万人。在同一年,与HIV和AIDS相关的死亡人数达到大约一百六十万人。
对于HIV感染的个体的现行疗法由批准的抗逆转录病毒药剂的联用药组成。目前批准了超过二十四种药物用于HIV感染,这些药物可以是单一药剂形式,或固定剂量的联用药形式,或单一片剂方案,后面的两种形式包含2-4种批准的药剂。这些药剂属于许多不同的类别,它们靶向病毒酶,或在病毒复制循环期间靶向病毒蛋白的功能。由此,药剂被分为核苷逆转录酶抑制剂(NRTI)、非核苷逆转录酶抑制剂(NNRTI)、蛋白酶抑制剂(PI)、整合酶抑制剂(INI)或进入抑制剂(一个是马拉维若(maraviroc),它靶向宿主的CCR5蛋白,另一个是恩夫韦地,它是靶向病毒gp160蛋白的gp41域的肽)。另外,没有抗病毒活性的药物动力学增强剂,即,Gilead Sciences, Inc.的可比西他(cobicistat),商品名称TYBOSTTM(可比西他(cobicistat))片剂,最近被批准可以与可受益于强化的某些抗逆转录病毒药剂(ARV)联用。
在美国(这里广泛地进行联合治疗),HIV相关的死亡数量已急剧下降(Palella,F. J.; Delany, K. M.; Moorman, A. C.; Loveless, M. O.; Furher, J.; Satten, G.A.; Aschman, D. J.; Holmberg, S. D. N. Engl. J. Med. 1998, 338, 853-860)。
令人遗憾的是,并不是所有患者对于这种疗法具有响应性,这种疗法对于大量患者来说是失败的。事实上,最初的研究表明,抑制性联用药中的至少一种药物对于大约30-50%的患者最终是无效的。在大多数情况下,治疗失败由出现病毒抗性引起。病毒抗性又是由如下而引起:HIV-1在感染期间的复制速率,与相对高的、与病毒聚合酶相关的病毒突变率以及HIV感染个体在服用他们的处方药物时缺乏坚持性。很明显,还需要新的抗病毒剂,优选,这种抗病毒剂针对已经耐受目前获批准的药物的病毒具有活性。与许多目前获批准的药物相比,其它重要因素包括:提高的安全性,以及更方便的给药方案。
已经公开了抑制HIV复制的化合物。参见,例如,下列专利申请∶WO2007131350、WO2009062285、WO2009062288、WO2009062289、WO2009062308、WO2010130034、WO2010130842、WO2011015641、WO2011076765、WO2012033735、WO2013123148、WO2013134113、WO2014164467、WO2014159959和WO2015126726。
现在,本领域需要的是新的和用于治疗HIV的其它化合物。另外,这些化合物可应需要提供药物使用的优点,例如,在它们的作用机理、结合性、抑制效果、靶向选择性、溶解度、安全性或生物利用率中的一或多个方面的优点。还需要使用这些化合物的新的制剂和治疗方法。
本发明概述
本发明包括式I的化合物,包括其可药用盐,以及药物组合物,和它们在抑制HIV和治疗被HIV或AIDS感染的患者中的用途。
借助于本发明,现在可能提供新的并且可用于治疗HIV的化合物。另外,所述化合物可以提供用于药物用途的优点,例如,在它们的作用机理、结合性、抑制效果、靶向选择性、溶解度、安全性或生物利用率一或多种方面的优点。
本发明还提供了含有本发明化合物(包括其可药用盐)和可药用载体、赋形剂和/或稀释剂的药物组合物。
另外,本发明提供了治疗HIV感染的方法,所述方法包括:给予患者治疗有效量的本发明的化合物。
另外,本发明提供了抑制HIV整合酶的方法。
按照本发明,还提供了制备本发明化合物的方法。
本发明涉及这些,以及下文所描述的其它重要方面。

生物学方法
抑制HIV复制∶
构建重组NL-RLuc原病毒克隆体,其中,用Renilla荧光素酶基因代替NL4-3的nef基因片段。这种病毒是完全感染性的病毒,并且可以在细胞培养物中进行多次复制循环。另外,荧光素报告基因为对病毒生长的程度进行定量提供了简易的方法,并因此可以对试验化合物的抗病毒活性进行定量。质粒pNLRLuc包含原病毒NL Rluc DNA,其在PvuII位点克隆到pUC18上。通过用质粒pNLRLuc转染293T细胞,制备NL-RLuc病毒。使用Invitrogen(Carlsbad,CA)的LipofectAMINE PLUS试剂盒,按照生产商的说明,进行转染,并将产生的病毒滴定在MT-2细胞中。对于敏感性分析,在化合物的存在下,滴定的病毒用于感染MT-2细胞,培养5天之后,处理细胞,并通过表达的荧光素酶数量来定量病毒生长。试验培养基是补充有10%热失活的胎牛血清(FBS)、100单位/ml青霉素G/100单位/ml链霉素、10 mM HEPES缓冲液(pH7.55)和2 mM L-谷氨酰胺的RPMI 1640。至少2个实验的结果用于计算EC50值。使用Promega(Madison,WI)的Dual Luciferase试剂盒,定量荧光素酶。通过在化合物的系列稀释物的存在下进行培养,测定病毒对于化合物的敏感性。使用中值效应方程式的指数形式,计算50%有效浓度(EC50),其中,(Fa)=1/[1+(ED50/药物浓度)m](Johnson VA, Byington RT.Infectivity Assay. In Techniques in HIV Research. ed. Aldovini A, Walker BD.71-76. New York: Stockton Press.1990)。结果示于表1中。活性等于A是指:化合物的EC50≤ 100 nM,而B和C表示化合物的EC50在100 nM和1μM之间(B),或>1μM(C)。
表1.
对于本领域技术人员来说,很明显,本公开不局限于上述说明性的实施例,并且在不背离本公开实质特性的条件下,其可以通过其它具体形式来具体实施。因此,期望在各方面都认为这些实施例是说明性的和非限制性的,应参照的是附加的权利要求,而不是上述实施例,且由此在权利要求的等效含义和范围内的所有变化都被包括在其中。
