Bucladesine calcium salt(DC2797 calcium salt) is a membrane permeable selective activator of PKA.Target: PKABucladesine (bilateral infusion of 10 mM or 100 mM) leads to a significant reduction in escape latency and travel distance (showing an improvement in spatial memory) compared to the control, as assesed by Morris water maze task in male rats. Bucladesine at 1 mM and 5 mM concentrations infused within minutes after 0.5 mg nicotine infusion improves spatial memory retention in male rats [1]. Bucladesine (10 mM/side) combined with Nicotine (0.5 mM/side) results in a significant increase in the ChAT and VAChT immunoreactivity in CA1 regions, and increase in the optical density and amount of ChAT and VAChT immunostaining correlates with the decrease in escape latency and traveled distance in rats treated with Nicotine and low dose of Bucladesine [2].
