Description

治疗病毒感染和癌的苯并咪唑-2-氨基甲酸酯
技术领域
本发明是有效地治疗HIV和其它病毒感染和抑制癌和在哺乳动物(特别是人和温血动物)中肿瘤生长的药物组合物。此组合物包含苯并咪唑衍生物,其药学上可接受的盐或与其它病毒和癌治疗剂的混合物。
发明背景
HIV和其它病毒感染是主要死因。HIV是病毒在体内复制、攻击机体免疫系统的一种疾病。HIV病毒不易被摧毁,也没有好的机制使宿主细胞不复制病毒。单纯性疱疹是难以治愈(即使并非不可能)的另一种病毒感染。人们迫切期待治疗这些疾病和其它病毒感染的方法。显然,能靶向HIV病毒和抑制病毒复制的物质是极吸引人的。
癌是动物和人的主要死因。癌的确切病因不明,但是很多研究者已证明某些活动如吸烟或暴露于致癌剂与某些类型癌和肿瘤的发病率之间的联系。
很多类型化疗剂已证明对癌和肿瘤细胞有效,但并非所有类型的癌和肿瘤对这些化疗剂产生反应。不幸的是这些药物中很多也损伤正常细胞。这些化疗剂的确切作用机制并非总是明了的。
尽管癌治疗领域有所进展,但迄今最主要的治疗是手术、放射和化学治疗。化学治疗被认为是对付已转移的癌或特别有侵袭性的癌。这样的杀细胞剂或细胞抑制剂对生长指数高的癌即其细胞迅速分裂的癌作用最好。迄今,激素(特别是雌激素、孕酮和睾酮)、各种微生物产生的一些抗生素、烷化剂和抗代谢剂形成了肿瘤学家可利用的治疗的主体。对癌和肿瘤细胞有特异性而不影响正常细胞的理想的细胞毒剂将是特别令人满意的。不幸的是,并未发现这样的细胞毒剂,人们使用的是针对分裂特别快的细胞(肿瘤和正常细胞)的替代药物。
显然,因对肿瘤细胞有独特特异性而针对肿瘤细胞的物质的开发将是一个突破点。或者,对肿瘤细胞有细胞毒性而对正常细胞显示轻微作用的物质将是令人满意的。因此,本发明的目的是提供有效抑制哺乳动物肿瘤和癌生长而对正常细胞作用小或无作用的药物组合物。
更具体地说,本发明的目的是提供包含本文所限定的药物载体和苯并咪唑衍生物的抗癌药物组合物及治疗这些癌症的方法。
这些组合物对于病毒也有效,可用于治疗病毒感染。因此,本发明的另一个目的是提供治疗诸如HIV、流感和鼻病毒的病毒感染的方法。
从下面的本发明详细描述中,这些和其它的目的会变得明显起来。
发明概述
治疗哺乳动物特别是温血动物和人的病毒感染和癌症的药物组合物,包含药物载体和有效量的下式所示化合物或其药学上可接受的无机或有机酸盐或其混合物:其中,R选自H、羧基(-CO2H)、羟基、氨基或酯基(-CO2R′),其中R′选自烷基、卤代烷基、链烯基和环烷基,其中烷基具有1-8个碳原子,或CH3CH2(OCH2CH2)n,或CH3CH2CH2(OCH2CH2CH2)n或(CH3)2CH-,及

和(OCH(CH3)CH2)n-,其中n为1-3。较佳的烷基是直链的。卤素以在末端碳上取代、并以氯为佳。较佳的环烷基具有3-6个碳原子。环烷基还包括在烷基链上取代的环烷基,2-环丙基乙基、环丙基甲基、2-环丙基丙基或2-环丙基丙基或环己基甲基。较佳的化合物具有如下结构式:

C.HIV药物
用两大类药物(逆转录酶抑制剂和蛋白酶抑制剂)治疗HIV。AZT广泛用于治疗急性HIV。除草剂和杀真菌剂及其衍生物可与AZT合用于治疗急性HIV。它们并不干扰AZT的活性。
其它HIV药物和抗病毒剂可与本发明提供的治疗一起使用。这些药物包括逆转录酶抑制剂和蛋白酶抑制剂。这些药物可与除草剂或杀真菌剂同时使用或相继给药。
D.化疗剂
杀真菌剂和除草剂可与化疗剂合用。可以是相继的,用化疗剂使肿瘤变小,然后开始用除草剂或杀真菌剂进行治疗,或两种材料可一起给药。
化疗剂一般被分成与DNA-作用的药物、抗代谢物、与微管蛋白作用的药物、激素类药和其他药物如天冬酰胺酶或羟基脲等类。每类化疗剂可根据化合物或活性的类型而被进一步细分。可以相继给药的方法与除草剂或杀真菌剂合并使用的化疗剂主要包括与DNA-作用的药物、抗代谢物、与微管蛋白作用的药物这些类的成员。对于化疗剂及其给药方法的详细论述,参见Dorr等,癌症化疗手册(CancerChemotherapy Handbook),第2版,第15-34页,Appleton & Lange(Connecticut,1994),该文献在此引用作为参考。
为了减小肿瘤块或阻止癌细胞生长,化疗剂必须阻止细胞复制,还必须干扰细胞自我维持的能力。起这些作用的药物主要是顺铂之类与DNA-作用的药物及与微管蛋白作用的药物。
与DNA作用的药物包括烷化剂,如顺铂、环磷酰胺、六甲蜜胺;DNA链断裂剂,如博来霉素;嵌入型拓扑异构酶II抑制剂,如放线菌素D和阿霉素;非嵌入型拓扑异构酶II抑制剂,如依托泊甙和替尼泊甙;以及DNA小沟结合剂普卡霉素(Plcamydin)。
烷化剂与细胞DNA、RNA和蛋白质分子,以及与更小的氨基酸、谷胱甘肽及类似化学物质形成共价的化学加合物。一般,这些烷化剂与细胞组分中的亲核原子反应,如在核酸、蛋白质、氨基酸或谷胱甘肽中的氨基、羧基、磷酸根、巯基。这些烷化剂在癌症治疗中的机制和作用还不十分了解。典型的烷化剂包括:
氮芥类,如苯丁酸氮芥、环磷酰胺、异环磷酰胺、氮芥(Mechlorethamine)、美法仑、乌拉莫司汀;
氮丙啶类如塞替派;
甲磺酸酯类如白消安;
亚硝脲类,如卡莫司汀、洛莫司汀、链佐星;
铂复合物类,如顺铂、卡铂;
生物还原烷化剂(alkylator),如丝裂霉素和丙卡巴肼、达卡巴嗪和六甲蜜胺;
DNA链断裂剂包括博来霉素;
DNA拓扑异构酶II抑制剂包括下列类型:
嵌入剂,如安吖啶、放线菌素D、柔红霉素、阿霉素、伊达比星和米托蒽醌;
非嵌入剂,如依托泊甙和替尼泊甙。
DNA小沟结合剂是普卡霉素。
抗代谢物通过两种主要机制中的一种或另一种而干扰核酸的产生。某些药物可抑制DNA合成的直接前体脱氧核苷三磷酸的产生,从而抑制DNA复制。某些化合物与嘌呤或嘧啶足够相象,从而可在核苷酸合成途径中代替它们。随后,这些类似物可代替正常的组分而进入DNA和RNA。可用于本发明的抗代谢物包括:
叶酸拮抗剂,如氨甲蝶呤和三甲曲沙;
嘧啶拮抗剂,如氟尿嘧啶、脱氧氟尿苷、CB3717、阿扎胞苷、阿糖胞苷、和氟尿苷;
嘌呤拮抗剂包括巯嘌呤、6-硫鸟嘌呤、氟达拉滨、喷司他丁;
糖修饰的类似物包括Cyctrabine、氟达拉滨;
核糖核苷酸还原酶抑制剂包括羟基脲。
与微管蛋白作用的药物通过结合于微管蛋白(一种可聚合形成细胞微管的蛋白质)的特异位点而起作用。微管是关键的细胞结构单元。当作用的药物结合于该蛋白质时,细胞不能形成微管。与微管蛋白作用的药物包括长春新碱和长春碱(两者都是生物碱),以及紫杉醇。
肾上腺皮质类甾醇类衍生自天然的肾上腺皮质醇或氢化可的松。可以使用它们,因为它们有消炎的优点而且某些能够抑制有丝分裂并抑制DNA合成。这些化合物包括:泼尼松、地塞米松、甲泼尼松龙和泼尼松龙。
羟基脲似乎主要通过抑制核糖核苷酸还原酶而起作用。
天冬酰胺酶是一种将天冬酰胺转变成无功能的天冬氨酸从而阻断肿瘤中蛋白质合成的酶。
激素类药物和黄体生成激素不常用于实质上减小肿瘤块。但是,它们可与化疗剂或除草剂或杀真菌剂合用。
激素阻断药也可用于治疗癌和肿瘤。它们可用于激素敏感性肿瘤,并且通常是从天然来源衍生。它们包括:
雌激素、结合雌激素和炔雌醇和己烯雌酚、氯烯雌醚和Idenestrol;
孕激素类,如己酸羟孕酮、甲羟孕酮和甲地孕酮;
雄激素类,如睾酮、丙酸睾酮、氟甲睾酮、甲睾酮;
促黄体生成激素释放激素类药或促性腺激素释放激素拮抗剂,主要被用于治疗前列腺癌。其中包括乙酸亮丙瑞林和乙酸戈舍瑞林。它们抑止睾丸生物合成类固醇。
抗激素类药包括:
抗雌激素剂如他莫昔芬(Tamosifen);
抗雄激素剂如氟他胺;和
抗肾上腺剂如米托坦和氨鲁米特。
E.增效剂
“增效剂”可以是任何这样的物质,它能提高或增加药物组合物的效力和/或作用于免疫系统。一种这样的增效剂是曲普利啶及其顺式异构体,它们可与化疗剂和杀真菌剂或除草剂合并使用。曲普利啶在US 5,114,951(1992)中有描述。另一种增效剂是丙考达唑,1H-苯并咪唑-2-丙酸;[β-(2-苯并咪唑)丙酸;2-(2-羧乙基)苯并咪唑;丙帕唑(propazol)]。丙考达唑是一种针对病毒和细菌感染的非特异的活性免疫保护剂,它可与此处所述的组合物一起使用。
增效剂可改善除草剂或杀真菌剂化合物的效能并可以安全有效量使用。这些联合使用可经口服给药、直肠内给药、局部给药或胃肠外给药法投药给患者或动物。
抗氧化维生素如抗坏血酸、β-胡萝卜素、维生素A和维生素E可与本发明组合物一起投药。
F.剂量
任何合适的剂量都可用于本发明方法。化合物和载体的类型以及数量可以很不相同,这取决于温血动物或人的种类、体重和待治疗的肿瘤。一般,合适的剂量是少至约2毫克(mg)/公斤(kg)体重,多至约4000毫克(mg)/公斤(kg)体重。较佳地,使用15毫克/公斤体重到多至约1500毫克/公斤体重。对于化疗剂,从约0.01毫克/公斤体重至约400毫克/公斤体重的较低剂量是可接受的,尽管高达1500mg/kg的量也可使用。可按本发明方法给予合适的剂量以治疗HIV。化合物和载体的种类及量可根据温血动物或人的种类而有很大差异。杀真菌剂或除草剂及其衍生物的范围和比例以及所用的HIV治疗剂因药物种类而异。一般来说,除草剂或杀真菌剂及其衍生物的剂量以低至约2mg/kg体重、高至约4000mg/kg体重为宜。更高的剂量(高达6000mg/kg体重)也可使用。除草剂或杀真菌剂以使用从15mg/kg体重至高达约3000mg/kg体重水平为宜。一般,给人的剂量低于给小温血动物如小鼠的剂量。剂量单位包括一种化合物,或者该化合物与其他化合物或其他抑制癌症的化合物形成的混合物。对于HIV药物,可用约0.01mg/kg体重至高达1500mg/kg体重。一般,给人的剂量低于给小温血动物如小鼠的剂量。剂量单位包括一种化合物,或者该化合物与其他化合物或其他抑制癌症的化合物形成的混合物。剂量单位还可含有稀释剂、填充剂(extender)、载体等。剂量单位可为固体或凝胶形式,如丸剂、片剂、胶囊剂等,或者是液体形式,它们适合口服给药、直肠给药、局部给药、静脉内注射或肠胃外给药,或者注射在肿瘤部位或其周围。
G.释药剂型
抗癌化合物一般与药物上可接受的载体混合。载体可以是固体、液体,一般根据所用的给药方式而选择类型。活性药物可以以片剂或胶囊、或作为附聚的粉末,或者以液体形式一起给药。合适固体载体的例子包括:乳糖、蔗糖、明胶和琼脂。胶囊或片剂可以容易地制备,并且便于吞咽或咀嚼;其他的固体形式包括颗粒和疏松粉末(bulk powder)。片剂可含有适当的粘合剂、润滑剂、稀释剂、崩解剂、着色剂、调味剂、流动诱导剂(flow-inducing agent)和助熔剂(melting agent)。合适的液体剂型的例子包括:在水、药物上可接受的脂肪和油、醇或其他有机溶剂(包括酯)中的溶液或悬浮液,乳剂、糖浆、酏剂、悬浮液、用非泡腾颗粒再生的溶液和/或悬浮液、以及用泡腾颗粒再生的泡腾制剂。这样的液体剂型可含有,例如,适当的溶剂、防腐剂、乳化剂、悬浮剂、稀释剂、甜味剂、增稠剂和助熔剂。口服剂型可任意含有调味剂和着色剂。肠胃外和静脉内给药的剂型还可含有矿物质和其他物质,以便使它们与注射或所选的释药系统类型相配伍。
可用于配制本发明口服剂型的、具体的药物上可接受的载体和赋形剂的例子,在美国专利No.3,903,297(1975年9月2日授予Robert)中有描述。用于制造本发明的有用剂型的技术和组合物,在下列文献中有描述:7种现代药剂(7Modern Pharmaceutics).第9和10章(Banker & Rhodes编,1979);Lieberman等,药物剂型:片剂(Pharmaceutical Dosage Forms:Tablets)(1981);和Ansel,药物剂型导论(Introduction to Pharmaceutical Dosage Forms)第2版(1976)。
H.治疗方法
治疗方法可以是,在治疗待治疗的具体病毒、癌或肿瘤类型时任何适当的有效的方法。治疗可以是口服给药、直肠给药、局部给药、肠胃外给药、静脉内给药、或者注射在肿瘤部位或其周围。施用或给予有效量药物的方法依据待治疗的肿瘤或病毒而有所不同。常采用静脉内、皮下或肌内施用与合适的载体一起配制的苯并咪唑衍生物的肠胃外治疗方法。在癌症治疗中,另外的抗病毒物质可与苯并咪唑衍生物一起使用,另外的抑制癌症化合物也可合用。可用稀释剂促进施用或给药,这是将化合物投予温血动物的较佳方法。
治疗病毒感染,将苯并咪唑衍生物多剂给药7至约21天,如果需要还可更长些,以抑制生长或杀灭病毒。在慢性感染的情况下,这些药物可能需要延长给药时间,可长达数年。
治疗急性病毒感染或HIV,苯并咪唑衍生物可在AZT治疗后给予或与其它HIV治疗一起进行。这些药物可以顺序给药方案给药,在该方案中首先减少体内HIV病毒,然后给予苯并咪唑衍生物使病毒不继续复制。在用苯并咪唑衍生物治疗过程中可继续进行AZT治疗。如果疾病在早期阶段,可给予苯并咪唑衍生物使病毒不再复制或生长,从而减慢疾病的进展。
在癌症治疗中,较佳为先给予苯并咪唑衍生物以明显地减小癌或肿瘤块的大小。通常这需要3至约14天。肿瘤或癌细胞水平的减小可达到小于原来水平的50%。放射治疗可与苯并咪唑衍生物治疗合用。
一旦肿瘤减小,立即给予苯并咪唑衍生物。由于该物质相对安全,如果需要,可给药14天至365天,以保持其在减少癌重新生长上的有效性。
下列实施例是阐述性的,并不意味着对本发明的限制。
