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.

The pyrimidine based azo-linked Schiff base ligand, 5-benzoyl-1-((E)-(2-hydroxy-3-methoxy-5-((E)phenyldiazenyl)benzylidene)amino)-4-phenylpyrimidin-2(1H)-one (HL), and its transition metal (II) complexes were synthesized and defined by using 1H-NMR, 13C-NMR, Elemental analysis, FT-IR, MS, UV–vis, molar conductance, magnetic susceptibility and thermal analysis techniques. According to the conductance data obtained indicate all of the metal complexes have non-electrolytic nature. Square pyramidal geometry for Pd(II) and octahedral geometry for all the other complexes synthesized was concluded from the electronic absorption spectra and magnetic susceptibility measurements of the complexes. Investigation of the significant infrared bands of the active groups in the ligand and the solid complexes alludes that HL is coordinated to the metal ions ONO tridentate manner. Moreover, the absorption and emission properties of the azo-azomethine based ligand and its complexes were investigated. The results obtained show that fluorescence emissions of the ligand and its metal (II) complexes depend on the type of transition metal ions and the derivatives displayed moderate Stokes’ shift values between 44 and 107?nm. All the compounds exhibited superb photostability. Further, antioxidant, antimicrobial and pBR322 plasmid DNA cleavage activities were investigated. All compounds showed good DPPH? (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity and complexes of [MnL2]?H2O and [NiL2]?H2O exhibited excellent metal chelating activity. All the compounds tested demonstrated two strand DNA cleavage activities.

Conventional solution-phase synthesis of azo compounds is complicated by the need for precise pH and temperature control, high concentrations of pH control reagents, and by-product removal. In this work, we exploited the advantages of microdroplet chemist
