摘要
Syntheses are reported for a series of 6-(o-methoxy-, o-ethoxy-, o-methylthio- and o-fluoro- phenoxy)-3-(methoxy and ethoxy)-2-phenyl(substituted phenyl and pyridin-3″-yl)imidazo[l, 2- b]pyridazines. 1C50 values are reported for the displacement of 3H-diazepam from rat brain membrane by each of these compounds. The most active compounds were found to be 3-ethoxy-2-(p-fluorophenyl)-6-(o-methoxyphen- oxy)-, 3-methoxy-6-(o-methoxyphenoxy)-2-(m-nitrophenyl) and 3-methoxy-6-(o-methoxyphen- oxy)-2-(3″, 4″-methylenedioxy)imidazo[l, 2-b]pyridazines with 1C50 values of 15, 18 and 19 nM respectively. © 1990 ASEG.
