Abstract
Syntheses are reported for 196-(N-benzyl-N-methylamino )-3-methoxy-2-phenyl(and substituted phenyl or pyridinyl ) imidazo [1,2-b] pyridazines from 6-(N-benzyl-N-methylamino)pyridazin-3- amine 2-oxide. The ability of each of these compounds to displace [3H]diazepam from rat brain membrane preparations was measured and the IC50 values (or percentage displacements) are reported and discussed. 6-(N-Benzyl-N-methylamino )-3-methoxy-2-phenylimido[1,2-b]pyridine was about half as active as its 6-bemylamino analogue, and the most active compound was 6-(N-benzyl-N-methylamino )-2-(2'-fluorophenyl)-3-methoxyimido[1,2-b] pyridazine with IC50 9.8 nM.
