摘要

A number of arylpiperazinylalkylpyridazinones structurally related to the previously described lead A (5-{[4-(3-chlorophenyl) piperazin-1-yl]-propyl}-3-methyl-7- phenylisossazolo [4, 5-d] pyridazin-4-(5 H)-one) were synthesized and tested for their analgesic activity. Many of the tested molecules, at the dose of 20 mg kg-1 po, showed high antinociceptive activity, in particular, compounds 5a, 11c, 15a, 21 and 22, which were able ...
