Preparation, structure and affinity for imidazoline I2 receptors and alpha2-adrenoceptors of 1-[(4,5-dihydroimidazolidin-2-yl)imino]indan-2-ols.
Two enantiomers IR, 2S-(+)-cis (3a) and IS, 2R-(-)-cis (3b) of 1-[(4,5-dihydroimidazolidin-2-yl)imino]indan-2-ol were prepared by reacting 2-chloro-4,5-dihydroimidazole (1) with corresponding 1-amino-indan-2-ols (2a-b). The compounds obtained are structural analogues of PMS 952 agent containing imino bridge in place of methylene group. Compound 3a exhibited moderate almost equal activity at both imidazoline I2 receptors and alpha2-adrenoceptors, while enantiomer 3b was found to be selective for alpha2-adrenoceptors (alpha2/I2 selectivity ratio = 10.4).
