The present invention relates to substituted 4-phenyltetrahydroisoquinoline compounds of the structure of formula I
and pharmaceutical compositions comprising them wherein the R groups are herein defined. These are excellent inhibitors of the sodium-hydrogen exchanger (NHE), in particular of the sodium-hydrogen exchanger of subtype 3 (NHE3). As such these compounds are useful in the treatment of various disorders of the renal and respiratory systems such as acute or chronic renal failure, pulmonary complications, biliary function disorders, respiratory disorders such as snoring or sleep apneas and cardiovascular/central nervous system disorders such as stroke. More specifically, the present invention relates to substituted 4-phenyl-tetrahydroisoquinolines, derivatives thereof and compositions containing them formulated in combination with other compounds which also regulate the intracellular pH environment such as inhibitors of carbonic anhydrase and inhibitors of the transport systems that carry bicarbonate ions, such as of the sodium-bicarbonate co-transporter (NBC) or the sodium-dependent chloride-bicarbonate exchanger
本发明涉及结构为式I的取代4-苯基四氢异喹啉化合物及包含它们的药物组合物,其中R基在此处定义。这些化合物是优秀的钠-氢交换体(NHE)抑制剂,特别是NHE3亚型的钠-氢交换体。因此,这些化合物在治疗肾脏和呼吸系统的各种疾病方面非常有用,如急性或慢性肾衰竭、肺部并发症、胆功能障碍、呼吸系统疾病如打鼾或睡眠呼吸暂停以及心血管/中枢神经系统疾病如中风。更具体地,本发明涉及取代的4-苯基四氢异喹啉、其衍生物以及含有它们的组合物,该组合物与其他调节细胞内pH环境的化合物一起配制,如碳酸酐酶抑制剂和携带碳酸氢根离子的转运系统的抑制剂,如钠-碳酸氢根共转运体(NBC)或钠依赖性氯化物-碳酸氢根交换体。
