A 61603 hydrobromide
Chemical Name: N-[5-(4,5-Dihydro-1H-imidazol-2-yl)-2-hydroxy-5,6,7,8-tetrahydronaphthalen-1-yl]methanesulfonamide hydrobromide
Biological Activity
A 61603 hydrobromide is a potent α-adrenoceptor agonist that is at least 35-fold more potent at α1A than at α1B or α1D sites. Induces dose response increases in spontaneous Ca2+ transients in rat ventricular myocytes in vitro (EC50 = 6.9 nmol/L).Technical Data
The technical data provided above is for guidance only.
