A series of novel positional oximes (2a–2d), O-methyl oxime ethers (3a–3d), and O-benzyl oxime ethers (4a–4d) were synthesized in high yields starting from their corresponding methyl 3-, 4-, 6-, and 13-keto tetradecanoates. The synthesized compounds were characterized by 1H NMR, 13C NMR, FT-IR, mass, and elemental analyses for their structures and (E) /(Z) isomerizations. Their DNA binding abilities were investigated in vitro by agarose gel electrophoresis. The antibacterial and antifungal activities were tested also in vitro against eleven bacterial strains and three fungal strains. |
