[Synthesis and benzodiazepine receptor binding studies of pyridazino[3,4-b]indoles].
A series of methyl 9H-pyridazino[3,4-b]indole-3-carboxylates and related compounds were synthesized using a Diels-Alder reaction of methyl 3-(1H-indol-3-yl)-2-propenoates and dibenzyl azodicarboxylate. Several compounds were found to have high affinity for the benzodiazepine receptor. Their structure-activity relationships are discussed.
