A series of 1,3-diarylpyrazolo[4,5-c]- and -[5,4-c]quinolin-4-ones were prepared and tested for their ability to displace [3H]flunitrazepam from bovine brain membranes. While the 1,3-diarylpyrazolo[4,5-c]quinoline derivatives showed affinity for the receptor site, their [5,4-c] isomers were devoid of binding activity.
