Journal ArticleDOI
Polycyclic guanidine alkaloids from the marine sponge Crambe crambe and Ca++ channel blocker activity of crambescidin 816
Roberto G. S. Berlinck,Jean Claude Braekman,Désiré Daloze,Ines Bruno,Raffaele Riccio,Sergio Ferri,Santi Spampinato,Ester Speroni +7 more
TL;DR: Four pentacyclic guanidine derivatives related to ptilomycalin A have been isolated from the Mediterranean sponge Crambe crambe and were found to have a potent Ca++ antagonist effect and to inhibit the acetylcholine-induced contraction of guinea pig ileum at very low concentrations.
Journal ArticleDOI
Nitric oxide down-regulates brain-derived neurotrophic factor secretion in cultured hippocampal neurons.
TL;DR: It is demonstrated that nitric oxide induces a rapid down-regulation of brain-derived neurotrophic factor (BDNF) secretion in cultured hippocampal neurons and the data indicate that the NO/cGMP/protein kinase G pathway represents a signaling mechanism by which neurons can rapidly down-regulate BDNF secretion.
Journal ArticleDOI
Involvement of Brain Serotonin in the Prolactin- Releasing Effect of Opioid Peptides*
Santi Spampinato,Vittorio Locatelli,Daniela Cocchi,Lucia M. Vicentini,Sandor Bajusz,Sergio Ferri,Eugenio E. Müller +6 more
TL;DR: The role played by brain serotonin (5-HT) neurotransmission in mediating the PRL-releasing effect of enkephalins was investigated in the rat and Metergoline significantly reduced the increase in plasma PRL due to EKNH2.
Journal ArticleDOI
Chronic opiate agonists down-regulate prodynorphin gene expression in rat brain
TL;DR: Chronic exposure to opiates appears to induce modifications of the endogenous opioid system, as regards gene expression regulation, in rat brain.
Journal ArticleDOI
Distinguishable effects of intrathecal dynorphins, somatostatin, neurotensin and s-calcitonin on nociception and motor function in the rat
TL;DR: MR 1452, a relatively preferential antagonist of the &kgr; opioid receptor, prevented both the antinociceptive and motor effects of dynorphins.
