英文摘要 | Our results showed that l-stepholidine (l-SPD) inhibited basal Ca2+ -ATPase activity in rat striatal synaptosomes with an IC50 of 31.5 mu-mol . L-1, suggesting its interaction with Ca2+ transport. l-SPD inhibited also calmodulin (CaM)-activated basal Ca2+ -ATPase in a concentration-dependent manner. A complete reversal of CaM activation of Ca2+ -ATPase was observed with l-SPD 10-mu-mol . L-1. The activity of synaptosomal Ca2+ -ATPase and membrane-bound CaM level were decreased in haloperidol (1 mg . kg-1 . d-1, ip) and l-SPD (5, 10, and 30 mg . kg-1 . d-1, ip) and for 7 and 14 d, respectively. But the activity of Ca2+ -ATPase and membrane CaM level were increased after treatment with the same of doses haloperidol and l-SPD for 21 d. During the treatments with haloperidol and l-SPD cytosolic and nuclear CaM levels were not altered. These results suggest that l-SPD may modulate the release and synthesis of dopamine (DA) and the negative feedback regulation of presynaptic DA receptors by altering Ca2+ and CaM regulating processes in the central dopaminergic nervous system. |
