Özet
Series of new mixed aza-oxo-thia macrocyclic ligands {2,6,12,16-tetraaza-1,7,11,17-tetraoxo-9,19-dithia-[(4'-methyl-5',4,3')(14'-methyl-15',14,13')]ditriazine}cyclocosane (L-1 ); {2,6,13,17-teraaza-1,7,12,18-tetraoxo-9,10,20,21-tetrathia-[(4'-methyl-5',4,3')(15'-methyl-14',16',15)]di-triazine}cyclodocosane (L-2 ); {2,6,14,18-tetraaza-1,7,13,19-tetraoxo-10,22-dithia-[(4'-methyl-5',3',4)(16'-methyl-15',17',16)]ditriazine}cyclotetracosane (L-3 ) and {2,6,15,19-tetraaza-1,7,14,12-tetraoxo-10,11,23,24-tetrathia-[(4'-methyl-5',4,3')(17'-methyl-8',17,16')]ditriazine}cyclohexa-cosane (L-4 ) were synthesized. The structural features of the compounds have been studied by elemental analyses, Mass, FT-Raman, FT-IR, H-1 and C-13 NMR spectroscopy. The antimicrobial activities of the ligands were evaluated using disk diffusion method in dimethyl sulfoxide as well as the minimal inhibitory concentration (MIC) dilution method, against 9 bacteria. The obtained results from disk diffusion method were assessed in side-by-side comparison with those of Penicillin-g, Ampicillin, Cefotaxime, Vancomycin, Oflaxacin, and Tetracyclin, well-known antibacterial agents. The results from dilution procedure were compared with Gentamycin as antibacterial and Nystatin as antifungal. The antifungal activities are reported on five yeast cultures namely Candida albicans, Kluyveromyces fragilis, Rhodotorula rubra, Debaryomyces hansenii, and Hanseniaspora guilliermondii, and the results are referenced with Nystatin, Ketaconazole, and Clotrimazole, commercial antifungal agents. In most cases, the compounds show strong antifungal activity in the comparison tests.
