其它N-取代的α-氨基羧酰胺衍生物以其具有药理学特性而为人们所熟悉,如英国专利号1140748中所述。根据该现有技术文件所提供的化合物可用于治疗和预防例如冠状动脉疾病和动脉粥样硬化疾病;此外,它们也可用于治疗发炎的症状,例如风湿性关节炎。
其它熟知的取代的氨基酸衍生物是脑菲肽酶(enkephalinase)抑制剂、止痛药和降压药,如EP-A-0038758中所述。
美国专利号US-A-4049663中还公开了其它的一些取代的甘氨酸和丙氨酸衍生物。根据该资料所提供的化合物作为口服止痛药具有治疗效果。
国际专利说明书WO-90/14334公开的N-苯基烷基取代的α-氨基羧酰胺衍生物对中枢神经系统是活性的。
已发现,新型取代的(芳烷基氨基苄基)氨基丙酰胺衍生物具有可贵的生物特性,它是本申请人从WO-90/14334中公开的衍生物中精选的,可特别用作镇颠痫剂、抗帕金森氏病剂、神经保护剂、抗抑制剂、镇痉剂和/或安眠剂。
因此,本发明提供了一种新型的式(I)的化合物式中n是1-4的整数;R和R1(各自相同或不同)是氢、卤素、三氟甲基或C1-C4烷氧基;R2是氢或C1-C4烷基;或其在医药上容许的盐;且其中,当R是氢、R1是氢或卤素和n为1时,R2不是氢或甲基。卤素原子优选氟、氯或溴,特别是氟或氯。-(CH2)n-基团可以是支链或直链的亚烷基链。C1-C4烷氧基基团可以是支链或直链的基团,典型的是甲氧基、乙氧基、丙氧基、异丙氧基、丁氧基或叔丁氧基,优选甲氧基或乙氧基。C1-C4烷基基团可以是支链或直链的基团,典型的是甲基、乙基、丙基、异丙基、丁基或叔丁基,优选甲基或乙基。
本发明优选的化合物是式(I)的化合物,其中,在服从上述的条件下,n是1、2、3或4;R是氢;R1是氢、卤素、C1-C4烷氧基或三氟甲基;R2是C1-C4烷基;及其在医药上容许的盐。
本发明优选的化合物的具体实例是:2-〔4-(2-甲氧基苄基)氨基苄基〕氨基丙酰胺;2-〔4-(3-甲氧基苄基)氨基苄基〕氨基丙酰胺;2-〔4-(2-三氟甲基苄基)氨基苄基〕氨基丙酰胺;2-〔4-(3-三氟甲基苄基)氨基苄基〕氨基丙酰胺;2-{4-〔2-(2-氟苯基)乙基〕氨基苄基}氨基丙酰胺;2-{4-〔2-(3-氟苯基)乙基〕氨基苄基}氨基丙酰胺;2-{4-〔3-(2-氟苯基)丙基〕氨基苄基}氨基丙酰胺;2-{4-〔3-(3-氟苯基)丙基〕氨基苄基}氨基丙酰胺;2-{4-〔4-(3-氟苯基)丁基〕氨基苄基}氨基丙酰胺;2-〔4-(3-苯基丙基)氨基苄基〕氨基丙酰胺;2-〔4-(2-苯基乙基)氨基苄基〕氨基丙酰胺;2-{4-〔4-(2-氟苯基)丁基〕氨基苄基}氨基丙酰胺;2-〔4-(4-苯基丁基)氨基苄基〕氨基丙酰胺;它们或是单一的(S)或(R)异构体或是其混合物及其在医药上容许的盐。
本发明还提供了一种新型的式(IA)的化合物式中,R3是氢;或其在医药上容许的盐。
式(IA)的化合物是根据WO-90/14334精选的一类化合物。
