Pyridazino[4,3-c]-isoquinolines having anti-anxiety activity
Benzodiazepine receptor binding and anticonflict activity in a series of 3,6-disubstituted pyridazino[4,3-c]isoquinolines devoid of anticonvulsant properties
摘要:
A series of 3,6-disubstituted pyridazino[4,3-c]isoquinolines were synthesized and tested for their ability to inhibit the binding of [3H]diazepam to rat brain receptors in vitro. Compounds bearing a phenyl, 4-methoxyphenyl, or methyl group at position 3 and a dialkylamino group at position 6 showed the highest affinity in the binding assay and were subsequently evaluated for their anticonflict and anticonvulsant effects. All of these compounds (5a-1 and 5q) were active in the Vogel rat conflict procedure, but none prevented convulsions in mice induced either by metrazol or bicuculline. 3-Phenyl-6-pyrrolidinylpyridazino[4,3-c]isoquinoline (5d) with a Ki = 11.4 nM in the binding assay exhibited the best potency in the anticonflict assay (MED 5 mg/kg ip) and did not produce neuromuscular impairment at the highest dose tested (50 mg/kg ip).
The present invention is directed to pyridazino [4, 3-c] isoquinolines of Formula I
wherein R represents methyl, phenyl or substituted phenyl groups, R1 represents inter alia amino or substituted amino, alkoxy or cycloalkoxy groups, having pharmacological activity, to process for preparing them and to the pharmaceutical compositions containing them. The compounds of the invention possess anti-anxiety activity.
