Abstract
In our earlier attempt, we have successfully synthesized and evaluated the antioxidant ability of the metal complexes of the chalcone-triazine hybrid with phenoxy [-6-phenoxy-] group at C6. Herein, we hypothesized that the substitution of phenyl amino [-6-(phenyl)amino-] group would enhance the biological effects of the metal complexes of chalconce-triazine hybrids. It is observed that the antioxidant ability of the metal (Cu2+, Co2+, Zn2+, Fe2+) complexes of chalcone-triazine hybrids with -6-phenoxy- or -6-(phenyl)amino- substitutions at are almost same (< 35 μg/mL). Whereas, the novel chalconce-triazine hybrids with -6-(phenyl)amino- exhibited antibacterial effect on E. coli and S. aureus (> 10 mm zone of inhibition) which was absent in the earlier one. In specific, the Cu-complex of (1-(2,4-dihydroxyphenyl)-3-(4-((4-((4-nitrophenyl)amino)-6-(phenyl)amino)-1,3,5-triazin-2-yl)oxy)phenyl)prop-2-en-1-one exhibited the highest antibacterial effect as 24.8 and 22.6 mm zone of inhibition on E. coli and S. aureus, respectively. Synthesized flavonoid metal complexes were characterized by Elemental Analysis, NMR, FT-IR, UV–Visible spectroscopy and XRD analytical techniques.
