A series of 1-[(imidazolidin-2-yl)imino]-1H-indole analogues of hypotensive α2-AR agonists, 1-[(imidazolidin-2-yl)imino]-1H-indazoles, was synthesized and tested in vitro for their activities at α1- and α2-adrenoceptors as well as imidazoline I1 and I2 receptors. The most active 1-[(imidazolidin-2-yl)imino]-1H-indoles displayed high or moderate affinities for α1- and α2-adrenoceptors and substantial selectivity for α2-adrenoceptors over imidazoline-I1 binding sites. The in vivo cardiovascular properties of indole derivatives 3 revealed that substitution at C-7 position of the indole ring may result in compounds with high cardiovascular activity. Among them, 7-fluoro congener 3g showed the most pronounced hypotensive and bradycardic activities in this experiment at a dose as low as 10?μg/kg i.v. Metabolic stability of the selected compounds of type 3 was determined using both in vitro and in silico approaches. The results indicated that these compounds are not vulnerable to rapid first-phase oxidative metabolism.

A survey of several electrophilic ammonia reagents for the N-amination of indole- and pyrrole-containing heterocycles revealed that monochloramine (NH2Cl) is an excellent reagent for this transformation. Pyrroles and indoles containing a variety of substitution were aminated on nitrogen with isolated yields ranging from 45% to 97%.
