本发明涉及具有5-羟色胺能作用的吲唑酰胺化合物,其制备方法及其药物组合物。
在众多已知的5-羟色胺能受体中,最近才在泌尿膀胱、平滑肌和心肌及中枢神经系统的特定区域鉴定出5HT4受体。对这类受体具有激动、部分激动和拮抗作用的化合物对胃肠运动紊乱、中枢神经系统紊乱、小便失禁和心率不齐的药物治疗会带来潜在的益处。实际上这些化合物的作用是通过模拟或拮抗5-羟色胺的能力发生的,这些能力包括通过活化肠神经原刺激肠蠕动,调节重要的脑过程,如锻炼、记忆和焦虑,诱导泌尿膀胱松弛和增加动脉收缩的频率。
业已发现一类对5HT4受体具有亲合力并作为5-羟色胺的部分激动剂或拮抗剂发挥作用的吲唑酰胺化合物。
因此,本发明的第一个目的是提供通式如下的吲唑酰胺化合物及其与药用有机和无机酸形成的酸加成盐和其药用季盐:
