摘要:
Pre-clinical characterization of novel substituted pyrrolidines that are high affinity histamine H-3 receptor antagonists is described. These compounds efficiently penetrate the CNS and occupy the histamine H-3 receptor in rat brain following oral administration. One compound, (2S,4R)-1-[2-(4-cyclobutyl-[1,4]diazepane-1-carbonyl)-4-(3-fluoro-phenoxy)-pyrrolidin-1-yl]-ethanone, was extensively profiled and shows promise as a potential clinical candidate.
