PRE- AND POSTJUNCTIONAL α-ADRENOCEPTORS IN RABBIT ARTICULAR BLOOD VESSELS
Previous in vitro work on rabbit knee joint vessels showed that vasoconstrictor effects of nerve stimulation and administration of α-adrenoceptor agonists were mediated predominantly by α1-adrenoceptors5,9 The present experiments were performed to assess the nature of α-adrenoceptor subtypes within these blood vessels in vivo. Dose/response relationships for adrenaline and noradrenaline pr...
متن کاملPhenotype pharmacology of lower urinary tract α(1)-adrenoceptors.
α(1)-Adrenoceptors are involved in numerous physiological functions, including micturition. However, the pharmacological profile of the α(1)-adrenoceptor subtypes remains controversial. Here, we review the literature regarding α(1)-adrenoceptors in the lower urinary tract from the standpoint of α(1L) phenotype pharmacology. Among three α(1)-adrenoceptor subtypes (α(1A), α(1B) and α(1D)), α(1a)-...
متن کاملModulatory role of a constitutively active population of alpha(1D)-adrenoceptors in conductance arteries.
A constitutively active population of alpha(1D)-adrenoceptors in iliac and proximal, distal, and small mesenteric rat arteries was studied. The increase in resting tone (IRT) that evidences it was observed only in iliac and proximal mesenteric and was inhibited by prazosin (pIC(50) = 9.57), 5-methylurapidil (pIC(50) = 7.61), and BMY 7378 (pIC(50) = 8.77). Chloroethylchlonidine (100 micromol/l) ...
متن کاملTamsulosin potently and selectively antagonizes human recombinant α(1A/1D)-adrenoceptors: slow dissociation from the α(1A)-adrenoceptor may account for selectivity for α(1A)-adrenoceptor over α(1B)-adrenoceptor subtype.
We determined the binding affinity of tamsulosin, a selective α(1)-adrenoceptor antagonist, for human α(1)-adrenoceptor subtypes in comparison with those of other α(1)-adrenoceptor antagonists including silodosin, prazosin, 5-methylurapidil, terazosin, alfuzosin, nafopidil, urapidil and BMY7378. The association and dissociation kinetics of [(3)H]tamsulosin for recombinant human α(1)-adrenocepto...
