Description
发明背景
发明领域。
本发明提供具有药物和生物活性的化合物、其药用组合物以及应用方法。特别是,本发明涉及吲哚氧代乙酰基哌嗪衍生物。这些化合物无论单独使用或者与其它抗病毒药、抗感染药、免疫调制剂或HIV侵入抑制剂结合使用,都具有独特的抗病毒活性。更详细地说,本发明涉及治疗HIV和AIDS。
背景技术
HIV-1(人体免疫缺陷病毒-1)感染一直是一个主要医学问题,全世界大约有33,400,000感染此病的人。目前所用的HIV药物包括6种核苷逆转录酶(RT)抑制剂(齐多夫定、去羟肌苷、stavudine、拉米夫定、扎西他滨和abacavir)、3个非核苷逆转录酶抑制剂(奈韦拉平、delavirdine和efavirenz)以及5个肽模拟蛋白酶抑制剂(沙奎那韦、indinavir、ritonavir、nelfinavir和amprenavir)。这些药物的每一个在单独使用时只能暂时地抑制病毒的复制。但是当联合使用时,这些药物对疾病的进展具有很大的作用。事实上,最近已有资料证明联合用药可明显降低AIDS病人的死亡率。尽管有这些结果,但有30-50%的患者最终停止了联合用药疗法。药物不够有效、非依从性、有限的组织渗透性以及药物在某些细胞类型内作用专一性的限制(如大多数核苷类似物在静息细胞内不能被磷酸化)可能是不能完全抑制敏感病毒的原因。另外,与频繁渗入突变结合的HIV-1的高复制率和快速周转也是导致以低于最适药物浓度给药时出现抗药性变体和治疗失败的原因(Larder和Kemp,Gulick,Morris-Jones等,Kuritzkes,Vacca和Condra,Schinazi等以及Flexner,参考文献6-12)。因此,需要新的具有不同抗性方式、良好药物动力学以及安全性的抗-HIV药物来提供更好的治疗选择方案。
目前市场上的HIV-1药物主要是核苷逆转录酶抑制剂或肽模拟蛋白酶抑制剂。最近发现非核苷逆转录酶抑制剂在治疗HIV感染上具有越来越重要的作用。文献(DeClercq,参考文献13)已公开至少30种不同类别的NNRTIs。二吡啶基二氮杂酮(奈维拉平)、苯并噁嗪酮(efavirenz)和双(杂芳基)哌嗪衍生物(delavirdine)已批准用于临床。另外,已报道可作为HIV-1逆转录酶抑制剂的某些吲哚衍生物,包括吲哚-3-砜、哌嗪基吲哚、吡嗪基吲哚和5H-吲哚并[3,2-b][1,5]苯并噻氮杂衍生物(Greenlee等,参考文献1,Williams等,参考文献2,Remero等,参考文献3,Font等,参考文献14,Remero等,参考文献15,Young等,参考文献16,Genin等,参考文献17和Silvestri等,参考文献18)。吲哚-2-甲酰胺也被公开为细胞粘附和HIV感染抑制剂(Boschelli等,美国专利5,424,329,参考文献4)。最后,公开作为HIV-1蛋白酶抑制剂的3-取代吲哚天然产物(半可皆霉素A和B、didemethylasterriquinone和异可皆霉素)(Fredenhagen等,参考文献19)。但是,这些参考文献中未提及本发明的新化合物以及其抑制病毒感染(包括HIV感染)的用途。
以前公开过结构相关的化合物(Brewster等,参考文献20,Archibald等,参考文献21,American Home Products GB1126245,参考文献5)。但是,这些结构不同于本发明公开的结构,区别在于它们是对称的双(3-吲哚基乙醛酰胺)而不是不对称的芳酰基吲哚氧代乙酰基哌嗪衍生物,并且未提及可用于抗病毒感染。感兴趣的是,本发明公开的化合物中存在的吲哚部分是许多非核苷HIV-1逆转录酶抑制剂(包括Upjohn的Delavirdine)的共同特征(Dueweke等,1992,1993,参考文献22和23)。
另外,以下化合物是市售提供的,但未见报道可用作药物,尤其是用于哺乳动物抗病毒作用。

另外,还可将本发明化合物与其它类型的称之为HIV侵入抑制剂的治疗AIDS的药物结合使用。这些HIV侵入抑制剂的实例见DRUGS OF THE FUTURE 1999,24(12),第1355-1362页;CELL,第9卷,第243-246页,1999年,10月29日;和DRUG DISCOVERYTODAY,第5卷,第5期,2000年5月,第183-194页。
需清楚的是:与本发明化合物联合使用的AIDS抗病毒药、免疫调制剂、抗感染药、HIV侵入抑制剂或疫苗的范围并不限于以上表中所列内容,而是原则上包括与任何用于治疗AIDS的药用组合物的任何组合。
优选的组合是用本发明化合物和HIV蛋白酶抑制剂和/或HIV逆转录酶的非核苷抑制剂同时或交替治疗。联合用药中任选的四分之一组分是HIV逆转录酶的核苷抑制剂,如AZT、3TC、ddC或ddI。优选的HIV蛋白酶抑制剂是indinavir,它是N-(2(R)-羟基-1-(S)-2,3-二氢化茚基)-2(R)-苯甲基-4-(S)-羟基-5-(1-(4-(3-吡啶基-甲基)-2(S)-N’-(叔丁基甲酰胺基)-哌嗪基))-戊酰胺乙醇化物的硫酸盐,其可按照美国专利5,413,999合成。一般可以以每日三次,800mg的剂量给予indinavir。其它优选的蛋白酶抑制剂是nelfinavir和ritonavir。另一优选的HIV蛋白酶抑制剂是沙奎那韦,其以每日三次,600或1200mg的剂量给药。优选的HIV逆转录酶的非核苷抑制剂包括efavirenz。ddC、ddI和AZT的制备也可见EPO0,484,071。这些联合使用可能对限制HIV感染的传播和程度具有意想不到的作用。优选的组合包括与以下的组合(1)indinavir与efavirenz,以及任选AZT和/或3TC和/或ddI和/或ddC;(2)indinavir,和任何AZT和/或ddI和/或ddC和/或3TC,尤其是indinavir和AZT和3TC;(3)stavudine和3TC和/或齐多夫定;(4)齐多夫定和拉米夫定和141W94和1592U89;(5)齐多夫定和拉米夫定。
当本发明化合物与其它活性药物联合应用时,可分别给药或同时给药。另外,一种成分药物的给药可在其它药物给药之前、给药同时或给药之后进行。
原料吲哚1(方案1)是已知化合物或者可根据文献方法容易地制备,如Gribble,G.(参考文献24)或Bartoli等(参考文献36)。根据文献方法(Lingens,F.等,参考文献25),在THF(四氢呋喃)或乙醚中,将吲哚1用草酰氯处理得到所要求的乙醛酰氯(glyoxyl chloride)2。然后在碱性条件下,使中间体乙醛酰氯2与苯甲酰基哌嗪3(Desai,M等,参考文献26)偶合得到4。 方案2
将吲哚-3-乙醛酰氯2(方案2)用1-哌嗪甲酸叔丁酯5处理得到偶合的产物6。将6的Boc基用20%(三氟乙酸)TFA/CH2Cl2脱保护得到7。然后在聚合物载体上的1-(3-二甲氨基丙基)-3-乙基碳化二亚胺(P-EDC)存在下,使该产物与羧酸偶合得到产物8。 方案3
对于实施例82-89而言,可在EDC存在下,将哌嗪7(方案4)用乙酰氧基苯甲酸处理得到8b。分离部分得到的产物,经LiOH水解以除去乙酸酯基,而得到羟基衍生物10。
用以下方案5-13中说明的方法制备含有取代哌嗪的实施例化合物。
取代的哌嗪可由Aldrich公司提供或者根据文献方法(Behun等,参考文献31(a),方案5,eq.01)制备。在40-50psi压力下,在乙醇中,将烷基取代的吡嗪氢化生成取代的哌嗪。当取代基是酯或酰胺时,可将该吡嗪系统部分还原生成四氢吡嗪(Rossen等,参考文献31(b),方案5,eq.02)。可在以上说明的相同条件下,通过使用市售提供的二苄基哌嗪制备羰基取代的哌嗪(方案5,eq.03)。 方案5
通过4步路线(方案6)制备2-三氟甲基哌嗪(Jenneskens等,参考文献31c)。用Lewis酸TiCl4,使N,N’-二苄基亚乙基二胺11与三氟丙酮酸酯12反应得到半缩醛13,室温下,在CF3COOH中,将13用Et3SiH还原生成内酰胺14。然后用LiAlH4处理,将内酰胺14还原成1,4-二苄基-2-三氟甲基哌嗪15。最后,在HOAc中,将化合物15氢化得到所要求的产物2-三氟甲基哌嗪16。 方案6
通过采用以下一种方法(方案7)可制备单-苯甲酰基化的对称取代的哌嗪。(a)将哌嗪的乙酸溶液用乙酰氯处理生成所要求的单-苯甲酰化的哌嗪(Desai等,参考文献26,方案7,eq.04)。(b)将对称的哌嗪用2当量的正丁基锂处理,然后室温下加入苯甲酰氯制备(Wang等,参考文献32,方案7,eq.05)。方案7
单-苯甲酰基化的不对称取代的哌嗪可通过采用以下一种方法制备(方案8),其中所有方法都可通过单-烷基取代的哌嗪说明。(a)将不对称哌嗪用2当量的正丁基锂处理,然后室温下加入苯甲酰氯制得两种区域异构体的混合物,其可通过色谱分离(Wang等,参考文献32和33(b),方案8,eq.06);(b)将苯甲酸转化为其五氟苯基酯,然后再与2-烷基哌嗪反应生成在立体障碍较小的氮上带有苯甲酰基的单-苯甲酰基哌嗪(Adamczyk等,参考文献33(a),方案8,eq.07);(c)在二氯甲烷中,将哌嗪和苯甲酸甲酯混合物用二烷基氯化铝处理2-4日,生成在立体障碍较小的氮上带有苯甲酰基的单-苯甲酰基哌嗪(方案8,eq.08);(d)将不对称哌嗪用2当量的正丁基锂处理,然后室温下顺次加入三乙基甲硅烷基氯和苯甲酰氯的THF溶液,生成在立体障碍较大的氮上带有苯甲酰基的单-苯甲酰基哌嗪(Wang等,参考文献33(b),方案8,eq.09)。当2位上的取代基是酯或酰胺时,采用苯甲酰氯进行的单-苯甲酰基化反应可在哌嗪的立体障碍较小的氮上发生,该反应采用三乙胺作为碱,在THF中进行(方案8,eq.10)。方案8
在碱性条件下,如以K2CO3(方案11,eq.13)或NaOMe(方案11,eq.14)作为碱的MeOH和水中,可将哌嗪连接部分上的酯基或吲哚核上的酯基水解成对应的酸。 方案11偶合反应:
方案12
在CH2Cl2中,用i-Pr2NEt作为碱,使乙醛酰氯2与取代的苯甲酰哌嗪或四氢吡嗪(17)反应生成所要求的18。
在用3-羟甲基-苯甲酰基哌嗪进行偶合反应时,可用BSTFA(N,O-双三甲基甲硅烷基氟乙酰胺)将羟基暂时保护为其TMS(三甲基甲硅烷基)醚(Furber等,参考文献35)。然后使未保护的氮原子与乙醛酰氯2反应形成所要求的二酰胺。在处理过程中,除去TMS保护基团得到游离的羟甲基哌嗪二酰胺19(方案13)。 方案13抗病毒活性
实施例1-34化合物的抗病毒活性是在10μM化合物存在下,用被HIV-1的BRU株急性感染的MT-2细胞(CD4阳性T-淋巴细胞系)测定。在感染6日后,用逆转录酶试验(Potts,参考文献27)确定生成病毒的量。抗病毒结果见下表1。通过在一系列稀释的化合物存在下孵育细胞来确定化合物的细胞毒性,并采用XTT染料还原试验(Weislow,参考文献28)确定细胞成活力。所有化合物的50%细胞毒性浓度明显高于10μM,表明这些化合物是相对无毒性的。
实施例35-215化合物的抗病毒活性是在≤10μM浓度的化合物存在下,用被单轮感染HIV-1报道基团病毒感染的HeLa CD4CCR5细胞测定。在感染3日后,通过测定感染细胞中整合的病毒DNA中荧光素酶的表达来确定病毒感染的量(Chen等,参考文献41)。通过确定各化合物存在下感染细胞中荧光素酶表达的水平占无化合物存在下所观测到的感染细胞的百分数,并从100中减去所测定的值来计算每个化合物的百分抑制率。表1-4和9-13中说明:在≤10μM的浓度下,化合物呈现出抗病毒活性,而无明显的毒性。 表1
