Pyridazines, LXXII: On the synthesis of azinium and diazinium compounds structurally related to pyridazomycin.
Preparation of series of pyridine-, pyridazine-, and pyrazine-derived carboxamides bearing at the ring N-atom an alkyl side-chain with a terminal carboxylic group (7-11) or with a terminal acetylamino malonic ester moiety (13-17, 19-23) is described. Two desaza-pyridazomycin derivatives (24, 26) and homologs thereof (25, 27) were synthesised. The novel compounds which are structurally related to the antifungal antibiotic pyridazomycin were screened for antifungal activity: preliminary in vitro tests showed no activity.
