title: Synthesis of quaternary 8-hydroxyquinoline and 8-hydroxyquinaldine-carbamates structurally related to cholinesterase.
abstract: The quaternary carbamates were synthesized by reaction of 8-hydroxyquinoline and 8-hydroxyquinaldine with alkylisocyanates, then quaternizing the carbamates produced with alkylhalides, aralkylhalides or sulphate. The UV spectra of the compounds obtained showed lambdamax at 285 nm. The new quaternary carbamates were found to be of high toxicity and parasymapathomimetic activity in white mice.
