Description
本发明涉及吲哚衍生物、制备它们的方法和中间体、含有它们的药用组合物和它们的医疗用途。本发明的活性化合物用于治疗肥胖症和其它疾病。
已经认识到肥胖症是受环境因素影响的疾病过程,其中传统的规定饮食和锻练以减少体重的方法需要补充治疗药物(S.Parker,“Obesity:Trends and Treatments”,Scrip Reports,PJB Publications Ltd,1996)。
某人是否属于超重或肥胖通常取决于他们体表面积指数(BMI),该指数用体重(kg)除以体表面积(m2)计算。因此,BMI的单位是kg/m2并且能够计算与每十年生命中最低死亡率相关的BMI值的范围。超重定义为BMI在25-30kg/m2的范围内,肥胖定义为BMI高于30kg/m2。该定义存在的问题在于它没有考虑到体重当中肌肉与脂肪(脂肪组织)的比例。结合这一点考虑,肥胖也可以根据身体脂肪含量来定义:在男性和女性中分别为高于25%和30%。
随着BMI的增加而增加了由于各种原因(与其它危险因素无关)引起死亡的危险性。与肥胖症有关的最常见的疾病是心血管疾病(特别是高血压)、糖尿病(肥胖使糖尿病的发展加快)、胆囊疾病(特别是癌症)和生殖系统疾病。研究已证明平稳适度地减少体重可以相应地明显降低发展为冠状动脉心脏病的危险。
作为减肥药出售的化合物包括奥利司他(Reductil)和西布曲明。奥利司他(脂酶抑制剂)抑制脂肪的直接吸收并且倾向于降低高发生率的不合人意(尽管相对无害)的付作用例如腹泻。西布曲明(混合的5-HT/去甲肾上腺素重摄取抑制剂)可以在一些病人中引起血压和心率增加。有报道认为5-羟色胺释放/重摄取抑制剂芬氟拉明(Pondimin)和右芬氟拉明(ReduxTM)可以长期(超过6个月)减少食物摄取和体重,然而,在报道了与其使用有关的心脏瓣膜异常的早期迹象后,这两种产品已被停止使用。因此,需要开发更安全的减肥药。
已经证明,非选择性的5-HT2c受体激动剂/部分激动剂间-氯苯基哌嗪(mCPP)和三氟甲基苯基哌嗪(TFMPP)可以减少大鼠的食物摄取(GA.Kennett和G.Curzon,Psychopharmacol.,1988,98,93-100;G.A.Kennett,C.T.Dourish和G.Curzon,Eur.J.Pharmacol,1987,141,429-453)并且加速出现饱满感(S.J.Kitchener和C.T.Dourish,Psychopharmacol.,1994,113,369-377)。在正常人志愿者和肥胖症受治疗者中采用mCPP的最新研究发现也表明降低食物摄取。因此,单纯注射mCPP可以降低女性志愿者的食物摄取(A.E.S.Walsh等,Psychopharmacol.,1994,116,120-122)并且在14天期的亚慢性治疗过程中降低男性和女性肥胖症受治疗者的食欲和体重(P.A.Sargeant等,Psychopharmacol.,1997,113,309-312)。mCPP在剔除5-HT2c受体的突变型小鼠体中缺乏厌食作用(L.H. Tecott等,Nature,1995,374,542-546)并且在大鼠体内被5-HT2c受体拮抗剂SB-242084拮抗(G.A.Kennett等,Neuropharmacol.,1997,36,609-620)。因此,mCPP似乎是通过在5-HT2c受体上的激动作用来降低食物摄取。
已经提出作为5-HT2c受体激动剂用于治疗肥胖症的其它化合物包括在EP-A-0655440中公开的取代的1-氨基乙基吲哚。CA-2132887和CA-2153937公开三环1-氨基乙基吡咯衍生物和三环1-氨基乙基吡唑衍生物与5-HT2c受体结合并且可以用于治疗肥胖症。WO-A-98/30548公开氨基烷基吲唑化合物作为5-HT2c激动剂用于治疗中枢系统疾病和食欲调节障碍。在J.Med.Chem.,1970,13,327和J.Med.Chem.,1973,16,1411中报道了作为合成杀锥虫药的取代的1,2,3,4-四氢咔唑。在US2687414和US 2541211中公开了9-(2-二烷基氨基丙基)-1,2,3,4-四氢咔唑。在DE 930988中公开了7-取代-9-(2-二烷基氨基乙基)-1,2,3,4-四氢咔唑。在J.Med.Chem.,1964,69,2910中公开了2,3-聚亚甲基吲哚的药理学性能。在J.Med.Chem.,1964,7,625中介绍了作为抗抑郁药的多环吲哚的衍生物。在US 3142678中公开了具有药理特性的氨基-取代的环戊二烯并噻吩并吲哚(penthienoindole)。在FR 2242983和DE2438413中公开了1,2,3,4-四氢环戊二烯并(cyclopent)[b]吲哚。在Khim.Geterotskikl.Soedin,1970,6,371中介绍了4-(3-氨基丁基)-1,2,3,4-四氢环戊二烯并[b]吲哚。
