Novel series of 4,6-disubstituted-1,3,5-triazines containing hydrazone derivatives were synthesized employing ultrasonic irradiation and conventional heating. The ultrasonication gave the target products in higher yields and purity in shorter reaction time compared with the conventional method. IR, NMR (1 H and 13 C), elemental analysis, and LC-MS confirmed the structures of the new products. The antimicrobial and antifungal activities were evaluated for all the prepared compounds against some selected Gram- positive and Gram-negative bacterial strains. The results showed that only two compounds 7i (pyridine derivative) and 7k (4- chlorobenzaldehyde derivative) displayed biological activity against some Gram-positive and Gram-negative bacteria, while the rest of the tested compounds did not display any antifungal activity.
Molecular and supramolecular structures of two polymeric and one trinuclear Cd(II) complex with hydralazine-type ligands were presented.
DMB (Dimethylbarbituric) and DETB (Diethylthiobarbituric) are both barbituric and thiobarbituric acid derivatives respectively, that forms enamines with the Nα amine of amino acids.
