Description

新化合物
本发明涉及具有药理活性的新化合物,它们的制备方法,含有它们的组合物以及它们在治疗CNS疾病中的用途。
EPA 0 021 580和EPA 0 076 072公开了具有抗心律失常活性的磺胺衍生物。现在已经发现了一类结构上有很大差异的化合物,其对5HT6受体具有拮抗活性。5HT6受体拮抗剂被认为对治疗某些CNS疾病有效,这些CNS疾病包括焦虑,抑郁,癫痫症,强迫观念与行为病,偏头痛,阿尔茨海默氏病,睡眠紊乱(包括24小时节律紊乱),进食紊乱如食欲不振和食欲过盛,恐慌发作,滥用药物脱瘾如***,酒精,尼古丁和苯并二吖庚因,精神***症,以及与脊椎创伤和/或脑外伤如脑积水相关的疾病。人们希望本发明化合物能利于提高认知记忆力,还希望本发明化合物能用于治疗某些GI(肠胃)病,如IBS(过敏性肠综合征)。
因此,本发明首先是提供了式(I)化合物或其盐,其中P是苯基,萘基,蒽基,双环杂环,三环杂芳香环或5-7员杂环,每个环含有1-4个选自氧,氮或硫的杂原子;A是单键,C1-6亚烷基,C1-6亚烯基;B是SO2;R1是卤素,任选被一个或多个氟原子取代的C1-6烷基,C3-6环烷基,C2 -6链烯基,C2-6炔基,C1-6烷酰基,C1-6烷氧基,OCF3,羟基,羟基C1 -6烷基,羟基C1-6烷氧基,C1-6烷氧基C1-6烷氧基,硝基,氰基,NR10R11,其中R10和R11分别是氢,C1-6烷基或任选被取代苯基,SR11,其中R11定义如上,或者R1是任选被取代的苯基,萘基,双环杂环或5-7员杂环,其中每个环含有1-4个选自氧,氮或硫的杂原子,或者R1与第二个取代基R1一起形成-O-CH2-O-,-O-CH2CH2-O-,-CH2CH2CH2-或-CH2CH2CH2CH2-;n是0,1,2,3,4,5或6;R2是氢,C1-6烷基,芳基C1-6烷基,或与P一起形成5-8员环,该环可任选被一个或多个C1-6烷基取代;R3是氢,卤素,C1-6烷基,C3-6环烷基,C1-6烷酰基,任选被一个或多个氟原子取代的C1-6烷氧基,羟基,羟基C1-6烷基,羟基C1-6烷氧基,C1-6烷氧基C1-6烷氧基,硝基,三氟甲基,氰基或芳基,或者与R5一起形成任选被一个或多个C1-6烷基取代的(CH2)2O(CH2)3O;R4是-X(CH2)p-R6,其中,X是单键,CH2,O,NH或N-烷基,p是0-6,而R6是任选取代的4-7员杂环,环中含有1-3个选自氮,硫和氧的杂原子,或R6是NR7R8,其中,R7和R8分别是氢,C1-6烷基或芳基C1-6烷基;及R5是基团R3,或与R3一起形成任选被一个或多个C1-6烷基取代的(CH2)2O或(CH2)3O。
无论是单独还是作为其它基团的一部分,C1-6烷基可以是直链或支链的。本文所用术语芳基包括苯基和萘基。当一个基团被定义为“任选被取代的”时,除非另有说明,合适的取代基包括卤素,C1-6烷基,C3-6环烷基,C1-6烷酰基,任选被一个或多个氟原子取代的C1-6烷氧基,羟基,羟基C1-6烷基,羟基C1-6烷氧基,C1-6烷氧基C1-6烷氧基,硝基,三氟甲基或氰基。
当P是双环杂环时,合适的例子有苯并噻酚,吲哚,喹啉或异喹啉。双环杂环还可以是部分饱和的。当P是三环杂芳香环时,合适的实例包括二苯并呋喃。合适的5-7员杂环包括噻吩基,呋喃基,吡咯基,***基,咪唑基,噁唑基,噻唑基,噁二唑基,异噻唑基,异噁唑基,噻二唑基,吡啶基,嘧啶基,吡咯烷基和吡嗪基。杂环可以通过适当碳原子,或者如果有氮原子存在,通过氮原子与分子的其余部分相连。优选的P是苯基或萘基。

合适的R1是氢,卤素,苯基,C1-6烷氧基,最优选OMe,SR11,最优选SMe或任选被一个或多个氟原子取代的C1-6烷基,例如,甲基或三氟甲基。优选的R1是卤素。优选的n是0,1,2,3或4。

式(I)化合物可以与酸形成酸加成盐,例如,与常用的可药用酸,如马来酸,盐酸,氢溴酸,磷酸,乙酸,富马酸,水杨酸,柠檬酸,乳酸,扁桃酸,酒石酸和甲磺酸。
式(I)化合物也可以形成溶剂化物,如水合物,而且本发明也扩展到这些形式。如果本文使用“式(I)化合物”一词,则应该理解为它包括这些形式。
某些式(I)化合物能够以立体异构体形式存在,包括非对映体和对映体形式,因此,本发明也扩展到每一个这些立体异构体形式和它们的混合物,包括外消旋体。不同的立体异构体形式可以用常规方法从一种分离得到另一种,或者通过立体有择或不对称合成得到任何一种式(I)化合物的异构体。本发明还包括所有互变异构形式和它们的混合物。
本发明还提供了制备式(I)化合物或其可药用盐的方法,该方法包括将式(II)化合物
Figure C9880692100221
其中R1,R2,n,P和A同式(I)中定义,或它们的保护的衍生物,与式(III)化合物进行偶合反应,
Figure C9880692100231
其中,B,R3,R4和R5同式(I)中定义,或它们的保护的衍生物,及L是离去基团,然后,任选以下步骤:·除去所有保护基,·形成可药用盐。
合适的离去基团包括卤素,特别是氯。式(II)和(III)化合物的反应是将两种试剂混合在一起进行的,任选在惰性溶剂,如二氯甲烷中,在有或没有适当的碱,如三乙胺(或吡啶)存在下进行。
本领域技术人员应该理解,有必要对某些基团进行保护。合适的保护基以及保护和脱保护方法是有机化学领域常用的,如GreeneT.W.,《有机合成中的保护基》(Protective groups in organicsynthesis),New York,Wiley(1981)。
式(II)和(III)化合物是商品,或者可以根据已知方法或类似方法制备。例如,在制备R3是H,R5是OMe和R4是1-哌嗪的式(I)化合物时,人们发现,三氯乙酰基是式(III)化合物的中间体的适宜保护基。因此,将1-(2-甲氧基苯基)哌嗪与三氯乙酰氯在适当溶剂,如二氯甲烷中,在碱,如二异丙基乙胺存在下反应,得到2-(4-三氯乙酰基-哌嗪-1-基)茴香醚。用氯磺酸在0℃在适当惰性溶剂,如二氯甲烷中进行处理,得到3-(4-三氯乙酰基哌嗪-1-基)-4-甲氧基苯磺酰氯。该化合物与上述式(II)化合物进行偶合反应,然后用20%氢氧化钾水溶液处理,最后得到所要的化合物。
可药用盐可通过将化合物与适当酸或酸衍生物的常规反应制成。
式(I)化合物及其可药用盐具有5HT6受体拮抗活性,而且被认为对治疗某些CNS疾病有效,如对焦虑,抑郁,癫痫症,强迫观念与行为病,偏头痛,阿尔茨海默氏病,睡眠紊乱(包括24小时节律紊乱),进食紊乱如食欲不振和食欲过盛,恐慌发作,滥用药物脱瘾如***,酒精,尼古丁和苯并二吖庚因,精神***症,以及与脊椎创伤和/或脑外伤如脑积水相关的疾病。人们还希望本发明化合物能用于治疗某些GI病如IBS。
因此,本发明还提供用作治疗物质,特别是用于治疗或预防上述疾病的式(I)化合物或其可药用盐。
本发明提供了治疗或预防包括人在内的哺乳动物之上述疾病的方法,包括给患者施用治疗有效量的式(I)化合物或其可药用盐。
另一方面,本发明提供了式(I)化合物或其可药用盐在制备治疗或预防上述疾病的药物中的用途。
本发明还提供了药物组合物,它含有式(I)化合物或其可药用盐以及可药用载体。
本发明药物组合物可以在室温和大气压下通过适当混合制备。该组合物通常适于口服,胃肠外或直肠给药,例如,制成片剂,胶囊剂,口服液,粉剂,颗粒剂,片剂,可再配粉剂,可注射或滴注溶液或悬浮液,或栓剂。通常优选可口服给药的组合物。
用于口服给药的片剂和胶囊剂可以是单剂形式,并含有常用的赋形剂,如粘合剂,填充剂,成片润滑剂,崩解剂和润湿剂。可以根据正常药物实践中已知的方法给片剂包衣。
口服液可以是,例如,水或油悬浮液,溶液,乳液,糖浆或酏剂,或是使用前可用水或其它适当载体再配的干燥产物。口服液中可以含有常用的添加剂,如悬浮剂,乳化剂,非水性载体(包括食用油),防腐剂和,如果需要,常用矫味剂和调色剂。
对于胃肠外给药,可用本发明化合物或其可药用盐以及灭菌载体制成液体单位剂型。取决于所用载体及其浓度,本发明化合物可以悬浮于或溶解于载体。在制备溶液时,为了注射,可先将化合物溶解,无菌过滤,然后装到适当的小瓶或安瓿中,最后密封。为了更好,可以在载体中再溶进一些辅剂,如局部麻醉剂,防腐剂和缓冲剂。为了提高稳定性,可以在将组合物装进小瓶并真空除去水之后将其冻干。胃肠外悬浮液基本上是用同样方法制备,只是将化合物悬浮于而不是溶解于载体中,而且灭菌过程也不用通过过滤方法实现。可以在将化合物悬浮于灭菌载体之前将其暴露于环氧乙烷来实现灭菌。可在组合物中加入表面活性剂或润湿剂以提高化合物分布的均匀性。
根据给药方式,组合物中可以含有0.1-99重量%,优选10-60wt%,活性物质。
用于治疗上述疾病的化合物剂量将以常规方式,依据疾病的严重程度,患者体重,以及一些其它因素而改变。但是,作为总的指导,合适的单位剂量是0.05-1000mg,0.05-20.0mg更合适,例如,0.2-5mg;而且,单剂可以每日给药一次以上,例如,一天两或三次,使每天的总剂量在约0.5-100mg范围;而且这种治疗可以延续几周或几个月。
当根据本发明给药时,人们希望本发明化合物没有不可接受的毒性作用。
