H Wachtel et al.
Neuropharmacology, 25(10), 1119-1126 (1986-10-01)
The antidepressant potential of rolipram and inhibitors of phosphodiesterase (PDE) which are selective for cyclic AMP has previously been ascribed to enhancement of central noradrenergic transmission by the combination of two mechanisms of action: increase of synthesis of noradrenaline and
Z Merican et al.
Clinical and experimental pharmacology & physiology, 8(1), 57-66 (1981-01-01)
1. Cyclic AMP levels have been determined in the soleus muscles of anaesthetized cats in the absence of drugs, and during depression of incomplete tetanic contractions produced by (-)-isoprenaline, ICI 63,197 (a phosphodiesterase inhibitor) or levodopa. 2. Cyclic AMP levels
A Bobik et al.
Journal of cardiovascular pharmacology, 6(5), 795-801 (1984-09-01)
We examined the effects of prolonged exposure of cardiac cells in primary culture to the partial beta-adrenoceptor agonist prenalterol and inhibitors of phosphodiesterase on their subsequent ability to increase intracellular cyclic AMP during a 5-min exposure to 50 microM isoprenaline
C B Archer et al.
The British journal of dermatology, 109(5), 559-564 (1983-11-01)
Peripheral blood lymphocyte cyclic AMP responses to isoprenaline, prostaglandin E2 and histamine were examined in patients with atopic eczema, in the presence and absence of a potent phosphodiesterase inhibitor (PDEI). Basal cyclic AMP levels were not significantly different in atopic
T Hermsdorf et al.
Cellular signalling, 10(9), 629-635 (1998-10-30)
Primary cultures of rat hepatocytes were used to study the combined effects of insulin and dexamethasone on cyclic AMP phosphodiesterase 3 (PDE 3) and glycogen metabolism. PDE activity was measured in extracts obtained by hypotonic shock treatment of the particulate
