| Research Abstract |
Tipepidine which has a blocking action on G-protein-coupled inwardly rectifying K ion channel revealed the improved actions in animal model of depression resistant to drug treatment, Parkinson disease and compulsive behaviors.These actions were produced at antitussive effective doses and through a novel mechanism. Tipepidine showed a relatively high selective action on GIRK channels. Combination study of NMR and gene expression system revealed that cloperastine may interact directly with E300, I302, C310 and Q311 of GIRK 1 subunit.
