Pyridazine N-oxides. II. Synthesis and in vitro antimicrobial evaluation of 3-chloro-4-carbamoyl-5-aryl-6-methyl-pyridazine N-oxides.

ABSTRACT

As a part of a research project on antimicrobial agents, various novel carbamoyl derivatives of pyridazine-N-oxides 7a-j were prepared in moderate to good yields from 3-chloro-4-ethoxycarbonyl-5-aryl-6-methyl-3-pyridazine. All compounds synthesized were ineffective against Gram+, Gram- bacteria and fungi while 7e and 7j exhibited a fairly good activity against Trichomonas vaginalis.
