Abstract
具有中枢神经系统活性的新磺胺类衍生物、它们的制备方法以及它们作为药物的用途。
Description
本发明涉及具有药理活性的化合物、它们的制备方法、含有这些化合物的组合物以及它们在治疗CNS疾病方面的用途。
EPA0 021 580和EPA0 076 072描述磺胺类衍生物,公开这些衍生物具有抗心律不齐的活性。目前我们发现了一类结构上显著不同的化合物,发现它们具有5HT6受体拮抗剂的活性。人们确信,5HT6受体拮抗剂在治疗某些CNS疾病中具有潜的能力,这些疾病如焦虑、抑郁症、癫痫、强迫观念与行为疾病、偏头痛、识别记忆增强,例如用于治疗早老性痴呆,睡眠障碍,进食障碍如厌食以及食欲过盛、恐慌发作、戒除由药物如可卡因、酒精、尼古丁、以及苯并二氮类引起的戒断症状,精神分裂症以及与脊柱创伤或头部创伤有关的疾病如脑积水。预期本发明的化合物也可以用于治疗某些GI(胃肠)疾病,如可用于治疗IBS(过敏性肠综合征)。
因此,在第一个方面本发明提供式(I)的化合物及其盐:其中:P为苯基、萘基、双环杂环或5-7元杂环,每个环含有1-4个选自氧、氮或硫的杂原子;A为单键、C1-6亚烷基或为C1-6亚链烯基;R1为卤素、被一个或多个卤原子任选取代的C1-6烷基、C3-6环烷基、COC1-6烷基、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、C1-6链烷酰基、硝基、氨基、C1-6烷氨基或二C1-6烷氨基、氰基,或者R1为苯基、萘基、双环杂环或5-7元杂环,每个环含有1-4个选自氧、氮或硫的杂原子;n为0、1、2、3、4、5或6;R2为氢、C1-6烷基或芳基C1-6烷基;R3为R5或与R5一起形成(CH2)2O或(CH2)3O基团,或者R3与R2连接形成(CH2)2或(CH2)3基团;R4为-X(CH2)p-R6其中X是单键、CH2、O、NH或N-C1-6烷基,而p为0-6,且R6为任选取代的5-7元杂环,该杂环含有1-3个选自氮、硫或氧的杂原子,或者R6为NR7R8,其中R7和R8独立为氢、C1-6烷基或芳基C1-6烷基;和R5为氢、卤素、C1-6烷基、C3-6环烷基、COC1-6烷基、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、C1-6链烷酰基、硝基、三氟甲基、氰基或芳基。
单独的或为其它基团的一部分的C1-6烷基均可以是直链的或支链的。优选的烷基通常是甲基和乙基。如在此所用芳基包括任选被取代的苯基和萘基。

式(I)化合物也可以形成溶剂化物如水合物,而且本发明也包括这些形式。因此可以理解在这里所指的术语“式(I)化合物”也包括这些形式。
式(I)的某些化合物可以存在立体异构体形式,包括非对映体和对映体,并且本发明包括这些立体异构体中的每一个以及它们的混合物包括外消旋体。不同的立体异构体可以通过常规方法分离,也可以通过立体有择合成或不对称合成得到所需同分异构体。本发明也包括互变异构体以及它们的混合物。

适当的离去基团包括卤素,尤其是氯。式(II)和(III)化合物的反应可以通过将该两种试剂任选在惰性溶剂如丙酮中混合进行。此反应可以在碱的存在下进行。
本领域技术人员可以理解可能需要保护某些基团。正如GreeneT.W.在《有机合成中的保护基团》(New York,Wiley(1981))中所述,适宜的保护基以及它们的连接和移去方法在有机合成领域中是常规的。例如,对于哌嗪基团而言,适宜的保护基团包括BOC、COCCl3、COCF3以及甲基,后者可以按照标准方法通过用1-氯乙基氯甲酸酯处理移去。
按照标准方法,通过对合适的NH-哌嗪化合物进行酰化或烷基化可以制备N-取代的哌嗪。
式(II)和(III)的化合物可以购自商业,或者可以通过已知的方法或类似已知的方法来进行制备。
通过与合适的酸或酸的衍生物进行反应可以方便地制备药学上可以接受的盐。
式(I)化合物及其药学上可以接受的盐具有5HT6受体拮抗剂的活性,因此我们相信可以用于治疗某些中枢神经系统疾病,如焦虑、抑郁症、癫痫、强迫观念与行为疾病、偏头痛、早老性痴呆(识别记忆增强)、睡眠障碍(包括生理节奏的失调)、进食障碍如厌食以及食欲过盛、恐慌发作,由药物如可卡因、乙醇、尼古丁以及苯并二氮类滥用引起的戒断症状,治疗精神分裂症,以及与脊柱创伤或头部创伤有关的疾病如脑积水。预期本发明的化合物也可以治疗某些胃肠病,如过敏性肠综合征。
因此,本发明也提供式(I)的化合物或其药学上可以接受的盐作为治疗药物尤其在治疗和预防上述疾病方面的用途。
本发明进一步提供治疗或预防哺乳动物(包括人类)上述疾病的方法,该方法包括给予患者治疗有效量的式(I)化合物或其药学上可以接受的盐。
另一方面,本发明提供式(I)化合物或其药学上可以接受的盐在生产治疗或预防上述疾病的药物中的用途。
本发明也提供了药用组合物,该组合物含有式(I)化合物或其药学上可以接受的盐以及一种药学上可以接受的载体。
本发明的药用组合物可以在室温及常压下进行混合制备,该药用组合物常规上可以口服、胃肠外给药或直肠给药,因此,可以制备成片剂、胶囊剂、口服液制剂、粉剂、颗粒剂,锭剂、可复制粉剂、可注射或输注的溶液或悬浮液或者栓剂。通常优选口服给药的组合物。
口服给药的片剂和胶囊剂可以为单位剂型,并且可以含有常规的赋形剂,例如粘合剂、填充剂、压片润滑剂、崩解剂以及可以接受的润湿剂。可以按照常规药物生产中熟知的方法对片剂进行包衣。
口服液制剂可以为如水或油的悬浮液、溶液、乳剂、糖浆剂或酏剂。或者可以制备成在使用前用水或其他适宜的溶媒复制的干燥产品形式。。这类液体制剂可以含有常规的添加剂如悬浮剂、乳化剂、非水溶媒(可以包括食用油)、防腐剂,并且如果需要可含有常规的矫味剂或着色剂。
胃肠外给药时,液体单位剂型可以用本发明的化合物或其药学上可以接受的盐与一种无菌的溶媒制备。根据溶媒的性质以及所使用的化合物的浓度,可以将化合物悬浮于或者溶解于溶媒中。在制备溶液时,可以将化合物溶解用于注射,并且在装入适宜的管制瓶或安瓿之前要过滤除菌并密封。最好将辅助剂如局部麻醉剂、防腐剂以及缓冲剂皆溶解在溶媒中。为了增加稳定性,组合物在装入管制瓶之后真空冷冻并除去水分。胃肠外给药的悬浮液基本上是以相同的方法制备,但是所述化合物是悬浮而不是溶解在溶媒中,而且不能通过过滤除菌。可以在将化合物悬浮于无菌的溶媒前,通过暴露于环氧乙烷进行灭菌。最好组合物中包括表面活性剂或润湿剂使得化合物均匀分散。
根据给药的方式,组合物中所含活性物质的量为0.1%到99%(w/w),优选的含量为10%到60%(w/w)。
在治疗前面提到的疾病时,所使用的化合物的剂量将根据疾病的严重性、患者的体重以及其它类似的因素而发生变化。可是作为常规的指导原则适当的单位剂量是0.05到1000mg,更适当的剂量是0.05到20.0mg,例如0.2mg到5mg,并且这样的单位剂量每天给药可以不止一次,例如一天2次或3次,以便使全天的剂量大约在0.5mg到100mg的范围内,这样的治疗可以延续数周或数月。
当按照本发明给药时,预期本发明的化合物无不能接受的毒性作用。
