title: Benzodiazepine receptor ligands. Synthesis and pharmacological evaluation of 6-aryl-3,8-disubstituted-1,2,4-triazolo[3,4-a]phthalazines.
abstract: A series of 6-aryl-3,8-disubstituted-1,2,4-triazolo[3,4-a]phthalazines was synthesised starting from suitable o-benzoylbenzoic acids. The compounds were tested in vitro for inhibition of the specific binding of 3H-Diazepam to benzodiazepine receptors in preparations of membranes from rat brain synaptosomes. None of the compounds was notably active in this test.
