2-(4,5-Dihydroimidazol-2-yl)benzimidazoles as highly selective imidazoline I2/adrenergic α2 receptor ligands
摘要:
2-(4,5-Dihydroimidazol-2-yl)benzimidazoles have been identified as selective imidazoline I-2/alpha(2)-adrenoceptor ligands. 4-Methyl (2) and 4-chloro (4) derivatives display 12 affinity at nanomolar concentration (K-i = 4.4 and 17.7 nM, respectively) and high I-2/alpha(2) selectivity ratio = 4226 and 5649, respectively. An evidence has been obtained that pK(a) value influences considerably the I-2/alpha(2)-selectivity ratio of this class of imidazoline 12 receptor ligands. (c) 2006 Elsevier Ltd. All rights reserved.
