A 61603 hydrobromide is a potent and selective agonist of α1A-adrenoceptor . α1A-adrenoceptor (α1A-AR) belongs to α1- adrenergic receptors, which include three subtypes α1A, α1B and α1D and play an important role in regulating cell growth and proliferation. A 61603 hydrobromide is a potent and selective α1A-adrenoceptor agonist. A-61603 was 35-fold more potent at α1A-AR than at α1B-AR or α1D-AR. In fibroblast cells transfected with α1A-AR, A-61603 significantly stimulated phosphoinositide hydrolysis . A 61603 exhibited affinity for α1A-AR, α1B-AR and α1D-AR with pKi values of 8.05/7.52, 5.68 and 5.87, respectively. Also, A 61603 exhibited agonist activities for α1A-AR, α1B-AR and α1D-AR with pEC50 values of 8.24/7.66, 6.50 and 5.59, respectively . In neonatal rat ventricular myocytes, A61603 significantly increased the frequency of Ca2+ transients with EC50 value of 6.9 nM in a dose-dependent way . In mesenteric vascular bed isolated from mice, A61603 significantly increased perfusion pressure with 235-fold higher potency than phenylephrine, which suggested that α1A-AR plays an important role in the control of blood pressure .
