title: Synthesis and binding studies of 1-arylpyrazolo[4,5-c]- and 2-arylpyrazolo[4,3-c]quinolin-4-ones. I.
abstract: The syntheses of some 2-aryl-3-methyl-4,5-dihydro-2H-pyrazolo [4,3-c] quinolin-4-ones and 1-aryl-3-methyl-4,5-dihydro-1H-pyrazolo-[4,5-c] quinolin-4-ones are reported. Some of the latter have shown a high activity in displacing specific [3H]-flunitrazepam binding from bovine brain membranes.
