详细

Schiff base compounds (((1Z,1^′Z)-(((ethane-1,2-diylbis(sulfanediyl))bis(2,1-phenylene))bis(azanylylidene)) bis(methanylylidene)) bis(4,1-phenylene))diboronic acid (1), 1,1′-((1Z,1′Z)-([1,1′-biphenyl]-4,4′-diylbis( azanylylidene)) bis(methanylylidene)) bis(naphthalen-2-ol) (2), 4,4′-((1Z,1′Z)-([1,1′-biphenyl]-4,4′-diylbis(azanylylidene)) bis(methanylylidene)) bis(2-methoxy phenol) (3), (N₄Z,N₄′Z)-N₄,N₄′-bis(4-(dimethyl amino) benzylidene)-[1,1′-biphenyl]-4,4′-diamine (4), (E)-2-((2-hydroxybenzylidene)amino) terephthalic acid (5), and (E)-2-(((2-hydroxynaphthalen-1-yl)methylene)amino)terephthalic acid (6) have been synthesized. The structural identification was confirmed by spectroscopic techniques. The antiproliferative, antiradical, and enzyme activities were investigated in biological experimen0ts. The obtained results showed that Schiff base compounds 1 – 6 exhibited meaningful features in various biological tests. A comparison of compound 1 (containing boron atom in the structure) to compounds 2 – 6 shows that the inclusion of boron in the Schiff base determines whether this would increase or not the efficiency in biological experiments. Hereby, compound 1 exhibited significantly different results in all applications.
