英文摘要 | AIM: To compare the effects of synthetic and natural (-)-huperzine A (Hup A) on cholinesterase and mouse water maze performance. METHODS: Spectrophotometry was used to determine cholinesterase activity. Mouse water maze was used to evaluate nootropic effect. RESULTS: The IC50 of synthetic Hup A for acetylcholinesterase (AChE) of rat cortex and rat erythrocyte membrane determined in vitro were 64.7 (52.6 - 79.5) and 53.9 (43.6 - 66.6) nmol . L-1, respectively, and for butyrylcholinesterase of rat serum was 53.6 (44.9 - 63.8) mu mol.L-1. Synthetic Hup A 0.12 - 0.48 mg. kg(-1) ig produced a dose-dependent inhibition of brain AChE in mice. Synthetic Hup A 0.05 mg: kg(-1) ig attenuated scopolamine-induced impairment of spatial memory. The efficacy of synthetic Hup A was the same as natural Hup A. CONCLUSION: Synthetic Hup A yielded an in. vitro and in vivo pharmacological profile of activities similar to that of natural Hup A. |
