Sa. Munk et al., ANALOGS OF UK-14,304 AS ALPHA(2)-ADRENOCEPTOR AGONISTS - TWIST AND AGENT POLARITY AS DESIGN ELEMENTS, Bioorganic & medicinal chemistry letters, 4(3), 1994, pp. 459-462
Tetrahydroquinoxaline analogs of UK 14,304 were prepared. These agents
proved to be highly polar, potent, and selective alpha(2)-adrenocepto
r agonists. This study suggested that agents bearing a twist of the im
idazoline ring relative to the quinoxaline nucleus prove more potent t
han planar analogs.
