title: [Lipoxygenase inhibitors. IV. Synthesis and cyclization reactions of open-chain N1-aryl-substituted amidrazones].
abstract: alpha-Carbonyl carboxylic acid arylhydrazonochlorides obtained by Japp-Klingemann reaction are the starting substances for the synthesis of alpha-carbonyl carboxylic acid arylhydrazonoamides, -esters and -thioesters. The inhibiting activity of these compounds against 15- and 5-lipoxygenase is described. Reactions of derivatives of amidrazones with formaldehyde give triazole, triazoline and unexpected benzotriazepine derivatives.
