Abstract
一种药用组合物,该组合物含有式I化合物,其中Rx为氰基或溴;R1为卤素;R2为C1-C3烷基;及其它们的药学上可接受的盐和前药以及一种至三种另外的抗逆转录病毒药物和药学上可接受的载体或稀释剂。本发明还涉及该组合物在制备用于治疗或预防HIV的药物中的用途。
Description
本申请是申请号为99803908.X(PCT/SE99/00053),申请日为1999年1月15日,发明名称为“抗病毒药物”的发明专利申请的分案申请。
技术领域
本发明涉及抗病毒药物领域并且特别涉及HIV逆转录酶抑制剂。本发明提供新的化合物、含有这些化合物的药用组合物和使用它们用于抑制HIV的方法。
背景技术
在HIV的治疗中,在HIV逆转录酶抑制方面已经显示出临床相应活性的药物当中,大多数为核苷类似物例如AZT、ddI、ddC和D4T。这些核苷类似物并不是象所要求的那样是特异性的,因此不得不以相对高的剂量水平给药。在这些剂量水平下,核苷类似物引起相当的毒性,限制了它们的长期使用。
为克服这些特异性和毒性问题,已开发多种所述HIV逆转录酶的非核苷类抑制剂。例如来自杨森公司的逆转录酶抑制剂TIBO在纳摩尔浓度下抑制HIV且未呈现出临床显著的毒性。TIBO和所述非核苷类逆转录酶抑制剂奈韦拉平两者迅速进行患者II期临床试验。然而,不久变得明显的是这些非核苷类抑制剂体内迅速选择出其对抗通常剂量的所述各自抑制剂的HIV突变型。例如在奈韦拉平情况中,仅在治疗四周后,患者血清中分离出的病毒与未治疗患者中分离出的病毒相比较对所述药物的敏感性低100倍(Drug Design & Discovery19928第255-263页)。对已进入临床试验的其它非核苷类RT抑制剂已出现了相似的模式,即当给予患者时,有体外活性的默克公司的L-697661和普强公司的地位韦啶(delavirdine)(U-87201)已迅速产生对抗HIV的突变型。尽管限于在尝试延缓抗药性的发展中的特定联合给药方案,具有上述缺点的奈韦拉平和地位韦啶最近已经登记用于临床。
国际专利申请第WO 95/06034号描述一系列新的脲衍生物,其呈现良好的体外抗HIV逆转录酶活性并在细胞培养中呈现良好的抑制HIV复制作用。然而,在WO 95/06034中所述化合物的实际应用受到它们不佳的药代动力学表现的阻碍。此外,与许多非核苷类逆转录酶抑制剂一样,在WO 95/06034中的化合物在缓慢抗药性发展的关键参数上和由其它的抗病毒药方案产生的抗HIV突变型活性的良好模式上留有改进的余地。
berg等于1995年在Santa Fe举行的ICAR上用墙报特别公开了以上提及的WO 95/06034中并具有下式的外消旋化合物
此时,以上描述的化合物被看作比含有带甲氧基/乙酰基的苯环的硫脲的变体具有更小的意义。然而,与现有技术的具有良好的药代动力学性质和延长的病毒抗药性的时间的化合物相比较,我们现已发现另外的取代模式证实它们具有改善的抗药性模式。因此,本发明提供了将非核苷类抑制剂优越的特异性与所有现有技术抑制剂缺乏的临床实用性相结合的抑制剂。
发明内容
本发明提供式I化合物:
其中
R1为卤素;
R2为C1-C3烷基;
Rx为氰基或溴;
和它们的药学上可接受的盐和前药。
本发明另外提供包括式I化合物和为此药学上可接受的载体或稀释剂的药用组合物。本发明另外的方面提供了抑制HIV的方法,该方法包括将式I化合物给予HIV的患者。本发明也扩展到治疗中式I化合物的用途,例如在制备用于治疗HIV感染的药物中的用途。
在治疗HIV引起的疾病中,所述式I化合物优选以达到大约10至1000nM的血浆水平的量给药并且更优选为100至500nM。这相应于依所述制剂的生物利用度而定的剂量比例为0.01至10mg/kg/天,优选为0.1至2mg/kg/天。正常成人的一般剂量比例将为每天大约0.05至5g,优选为每天一至四个剂量单位,0.1至2g例如500-750mg。
在权利要求1中特别关于药代动力学的优选的化合物子集具有所述结构IA:
其中R1和R2如上定义,包括它们的药学上可接受的盐和前药。
在式I中,特别易于形成前药的另一个有利的化合物子集包括其中Rx为溴的化合物。
R1优选为氯并且更优选为氟。适宜的R2基团包括甲基、异丙基、正丙基并且优选为乙基。
如上所述,所述环丙基环以顺式构型存在,允许存在两个对映体,1S,2S和1R,2R(分别和非常规指明在SE 980016-7和SE 9800113-4中为2R,1S和2S,1R):
这些对映体每一个为有效的抗逆转录病毒药物,尽管所述不同的对映体在生理性质上能够表现出细微的差异。例如所述1S,2S和1R,2R对映体在所述P450系统中能显示出不同模式的代谢。其中Rx为氰基的化合物的1S,2S对映体为特别优选,因为其独一无二地呈现出有能力避免所述P450系统中的关键成分。其它的逆转录病毒药物例如所述HIV蛋白酶抑制剂利托那韦(ritonavir)与所述P450系统广泛地相互作用,导致大量的不合乎需要的生理应答,其包括广泛改变其它联合给予药物的代谢。当患者期待多年(如果不是十年的话)服用多种药剂时,这与用于慢性感染所给予的药物特别相关。
式I化合物适宜的前药包括式II那些化合物:
其中
R1、R2和Rx如上定义,
R3为H、(CHm)nNR5R6;
R4为H、C1-C3烷基、(CHm)nNR5R6、(CHm)nC(=O)R5、(CHm)nOH、OR7、卤素、CF3或CN;或者

和它们的药学上可接受的盐。
其中Rx为氯的化合物的相应前药形成本发明的另一个方面。
在下文指的是X-环的含有X的环结构可为饱和的或具有1-3个不饱和键,包括具有芳香特征的环。优选的X-环包括环己环或环己烯环或者更优选为苯环。其它优选的X-环包括吗啉代或者更优选为吡啶环。或者,X-环可定义为五元环例如戊烯基或吡咯基。
在R3和R4结合形成含有任选杂原子的环的情况中,对X-环适宜的稠合环系统包括萘基、喹啉基、四氢异喹啉基、吲哚基或苯并咪唑环系统。在R4和R5结合形成环的情况中,对X-环的适宜的取代基环包括吗啉代和哌啶子基。这些稠合的或取代基的环可以被卤素、卤代甲基、氨基如(CHm)nNR5R6、C(=O)NR5R6、羟基、羟基甲基、羧基、羧基甲基、C1-3烷基、C1-3烷氧基等任选取代。

由X-环系统、R3、R4和如果存在的R5-R7表示的部分优选具有一点碱性。这能通过选择适宜的碱性杂环作为所述X-环,例如吡啶基或苯并吡啶基来达到。或者,R3至R7中的一个或多个可包含碱性取代基如伯、仲或叔胺、氨基酸等。
有利的R3和/或R4基团包括NH2、N(CH2)2和NHC1-3烷基如NHCH3或NHCH2CH3。R3优选处于相对于所述羰基和其任选的间隔基团的间位,尤其是当含有X的环为苯基或者当含有X的环为杂芳香环例如吡啶-3-基时,R3处于对位。通常优选的p和/或n的值为零,即各自的基团不存在。

结合动力学
NNRTI在所述靶酶上的结合与解离率能够直接通过表面细胞质基因组共振方法进行测试,其中将逆转录酶固定在嵌片的表面并且通过观察由伴随嵌片的质量增加或减少引起的折射率的变化来监控假定的抑制剂的结合或者解离。如同以上描述的那样,将本发明化合物(实施例8)与来自Santa Fe的最接近的现有技术的化合物进行比较。实验在Biacore 2000(Biacore AB,Uppsala,瑞典)上进行,使用BIA评价软件(3.0版)用于评价数据。所述小的分析物(NNRTI)对大得多的酶的结合导致在10-20 RU的范围内结合应答。在流动的缓冲液和样品之间的总体折射率的差异使得评价在注射样品期间得到的数据是困难的。在所述解离相期间,在总体折射率方面存在不明显的变化,因此在这个相中已评价了不同物质的结合。
固定:通过直接偶合于伯胺,所述酶和对照蛋白固定在CM5嵌片上(Markgren等,1998)。对Fc g(Biacore BR-1000-57)的抗体被用作对照蛋白并且按照制造商的说明书固定。使用Nanosept离心浓缩器10K(PalI Filtron,MA,U.S.A),将HIV逆转录酶(Unge等,1990)从3M的(NH4)2SO4转移至含有4mM MgCl2的5mM Hepes,pH 7.6中。将相应于6800-9700 RU量的RT固定于所述传感器嵌片上。通过注射35ml的0.5M Tris pH 7.6、4mM MgCl2、0.5M KCl钝化所述传感器表面。所述固定方法在33℃下进行。
与抑制剂的相互作用:将抑制剂的贮存液(1mg/ml在DMSO中)溶于RT流动的缓冲液(10mM Hepes pH 7.6、4mM MgCl2、0.25mM精胺、40 mM KCl、0.5%Triton X-100、3%DMSO、0.5%胎牛血清)中以达到10mM的浓度。通过注射200ml的所述稀释物质来分析物质对RT的结合,流速为20ml/min和温度为25℃。在每一次注射物质后,通过注射在RT的流动的缓冲液中的120ml的10%的DMSO洗涤所述系统。
所述结果在图3中得到描绘。显而易见地是本发明化合物和现有技术的化合物显示不同的相互作用动力学,本发明化合物具有最低的解离率,这表明其更有效地与所述酶结合。
