  • Title: Differential effects of chronic administration of desipramine on the cyclic AMP response in cortical slices and membranes in the rat.
    Author: Newman ME, Lipot M, Lerer B.
    Journal: Neuropharmacology; 1987 Aug; 26(8):1127-30. PubMed ID: 2821440.
    Abstract:
    Chronic administration of desipramine resulted in a significant decrease in the degree of stimulation of production of cyclic AMP by noradrenaline, isoproterenol and forskolin in slices of the cerebral cortex of the rat. In preparations of membranes from similarly treated animals, GppNHp- and forskolin-stimulated adenylate cyclase activity was increased, while isoproterenol-, manganese- and sodium fluoride-stimulated activity was unchanged. It is concluded that chronic administration of desipramine exerts effects on the adenylate cyclase system additional to its action on beta-adrenergic receptors, possibly by modifying the catalytic or guanyl nucleotide binding units of the enzyme.
