Synthesis, antimicrobial evaluation and spectroscopic characterization of novel imidazolone, triazole and triazinone derivatives.
The reactions of 2-phenyl-4-arylmethylene-2-oxazolin-5-ones (1a, b) and 2-phenyl-4-arylazo-2-oxazolin-5-ones (8a, b) with p-aminoazobenzene derivatives (2a-c) gave the corresponding imidazolone derivatives (4a-f) and triazole derivatives (10a-f), respectively. Also, the reaction of 1a with o-aminophenol to give the imidazolone derivative 5 was studied. The reaction of 1a with 2,4-dinitrophenylhydrazine gave the corresponding 1,2,4-triazine derivatives 14a-c, respectively. The newly synthesized compounds were screened for their antibacterial activity against Gram-positive (Bacillus subtilis and Bacillus thuringiensis), Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa) and in vitro antifungal potential against Fusarium oxysporum and Botrytis fabae fungal strains. The results revealed that the investigated compounds exhibited antibacterial and a significant antifungal activity.
