Synthesis and biological activities of 2-[(heteroaryl)methyl]imidazolines
摘要:
A series of 2-[(heteroaryl)methyl]imidazolines was synthesized and tested for their activities at alpha(1)- and alpha(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 alpha(1)- and alpha(2)-adrenoceptors. However, their intrinsic activities at alpha(2A)-adrenoceptors proved to be negligible. A selected 7-chloro derivative behaved as a potent alpha(1)-adrenoceptor antagonist and exhibited peripherally mediated hypotensive effects in rats. (C) 2011 Elsevier Ltd. All rights reserved.
