title: Synthesis and binding study on pyrazolo[4,5-c] [1,8]naphthyridines.
abstract: Following our previous reports on pyrazolo[4,5-c]quinoline derivatives some isosteric pyrazolo[4,5-c] [1,8]naphthyridines were synthesized and tested for their ability to displace [3H]flunitrazepam from rat brain membranes. The lack of activity of the synthesized compounds and structure-activity relationships for the whole series are discussed.
