SKF38393 (50-100 μM) induces long-lasting synaptic potentiation in a protein synthesis-dependent manner. In rat prefrontal cortical neurons in vitro, SKF 38393 mimicks the effects of DA on I(NaP), and modulates a persistent sodium current. In the auditory cortex, SKF38393 affects long-term memory formation and consolidation by activating the downstream effectors adenylyl cyclase and phospholipase C-prominent proteomic alterations.
In vivo
SKF 38393(6 mg/kg, i.p.) prevents the scopolamine-induced impairment of performance of a T-maze working memory task. In adult male NMRI mice, SKF38393 (1 μg/mouse) impaires context-dependent fear learning.
