Description

神经肽Y5受体拮抗剂
发明背景
本发明涉及可以用于治疗进食性疾病和糖尿病的选择性神经肽Y的Y5受体拮抗剂、含有这些化合物的药用组合物以及用这些化合物治疗疾病的方法。
神经肽Y为36个氨基酸的肽广泛分布于中枢和外周神经系统。该肽可通过其各种受体亚型介导多种生理作用。动物研究表明神经肽Y为食物摄取的有效的刺激因素,并且还证明神经肽Y的Y5受体的活化可以导致饮食过量和热产生减少。因此,在Y5受体亚型上拮抗神经肽Y的化合物为治疗进食性疾病如肥胖症和饮食过量的方法。
已知苯基酰胺类化合物和脲类化合物可以作为抗动脉硬化症的药物,可参见如美国专利4,623,662,在美国专利5,378,728中公开苯甲酰胺类化合物可作为抗糖尿病的药物。已知N,N-亚烷基双(苯甲酰胺)类化合物可以作为调节内分泌的药物,参见美国专利4,009,208。公开于1998年8月20日的WO98/35957描述了作为选择性神经肽Y受体拮抗剂的酰胺衍生物。

通过本领域技术人员已知的方法,可以制备式Ⅰ化合物,如下列实施例中所示。一般而言,可以采用下列反应流程制备其中X为-S-或-O-的所要求保护的化合物:其中使式Ⅱ的胺在碱存在下与酰氯或氨基甲酰氯反应,或者在标准的酰胺偶合剂如EDC和DMAP存在下与羧酸反应。用已知的方法,可以制备式Ⅱ原料。
