Some new DAMN-based Schiff base 6a–6g were synthesized via a condensation reaction of the corresponding azo dyes with 1-(2-amino-1,2-dicyanovinyl)-3-phenylurea. In continuation, facile synthesis of new 8,9-dihydro-7H-purine-6-carboxamide 7a–7g was reported via an efficient reaction of azo dyes and 1-(2-amino-1,2-dicyanovinyl)-3-phenylurea in the presence of triethylamine as catalyst. All the synthesized compounds were evaluated for their antibacterial activities against both Gram-positive (Micrococcus luteus and Staphylococcus aureus) and Gram-negative (Pseudomonas aeruginosa and Escherichia coli) bacteria.
