Bupranolol is an antagonist at the cardiostimulatory low-affinity state of ß1-adrenoceptors and we were interested whether this effect is shared by its fluorine (GD-6), methyl (DZ-51) and isopropyl analogue (DZ-13) and by the analogue hydroxylated at the tertiary butyl moiety (DZ-52). (-)-Bupranolol and compounds (-)-GD-6, (+)-GD-6, (-)-DZ-13, (+)-DZ-13, DZ-51 and DZ-52 antagonized the CGP 12177-induced...
We studied whether cannabinoid CB1 receptors occur on the sympathetic neurones innervating the guinea-pig atrium and renal cortex. Atrial and cortical kidney pieces preincubated with [3H]-noradrenaline were superfused and the electrically (3 Hz)-evoked tritium overflow was examined. The evoked overflow in atrium was inhibited by the cannabinoid agonist WIN 55,212-2 maximally by 35%; its concentration-response...
The aim of our study was to examine whether non ß1-/ß2-adrenoceptors participate in the relaxation of the human pulmonary artery. For this purpose the vasodilatory effect of the non-conventional partial ß-adrenoceptor agonist cyanopindolol was examined. Cyanopindolol (1 - 300 µM), studied in the presence of the ß1-/ß2-adrenoceptor antagonist propranolol, relaxed the human pulmonary artery preconstricted...
Nociceptin is the endogenous ligand of the opioid OP4 or ORL1 (opioid receptor-like1) receptor. It decreases blood pressure and heart rate in anesthetized and conscious rats and mice after its intravenous and intracerebroventricular injection in a manner sensitive to OP4 but not to OP1-3 (or , and µ opioid) receptor antagonists. OP4 receptors involved in the cardiovascular effects of nociceptin were...
