Abstract: A series of 2-[(heteroaryl)methyl]imidazolines was synthesized and tested for their activities at α(1)- and α(2)-adrenoceptors and imidazoline I(1) and I(2) receptors. The most active 2-[(indazol-1-yl)methyl]imidazolines showed high or moderate affinities for α(1)- and α(2)-adrenoceptors. However, their intrinsic activities at α(2A)-adrenoceptors proved to be negligible. A selected 7-chloro derivative behaved as a potent α(1)-adrenoceptor antagonist and exhibited peripherally mediated hypotensive effects in rats.
