title: Synthesis of new 6H-indolo[2,3-b] [1,8]naphthyridines and their specific inhibition of benzodiazepine receptor.
abstract: Some 3-amino- and 3-hydroxy-8-halosubstituted 6H-indolo[2,3-b] [1,8]naphthyridines were synthesized and tested for their affinity for the benzodiazepine receptor in bovine cortical membranes. All prepared compounds were more active than the corresponding 8-unsubstituted derivatives. Moreover, among these compounds the 8-chloroindolonaphthyridines were clearly the most potent.
