Öğe Novel unsymmetric diimines: Synthesis and biological evaluation against pathogenic microorganisms(Sami Publishing Company, 2020) Nartop, D.; Öğütcü, H.In this research study, three new unsymmetric diimines (3a-3c) were prepared using a two-step process. The synthesized unsymmetric tetradentate diimines were elucidated by FT-IR, 1H-NMR, LC-MS, elemental analysis techniques. The antimicrobial and the antifungal properties of newly synthesized unsymmetrical diimines (3a-3c) and previously reported by one of us unsymmetrical diimines (4a-4c) were evaluated against L. monocytogenes 4b, B. cereus sp., S. typhi H, Br. abortus, S. epidermis sp., M. Luteus sp., E. coli, P. putida sp. Sh. dys. typ. 7 ve C. albicans. 3b, 3c, 4a and 4c are showed the highest antimicrobial activity against B.cereus sp. 3a and 4b are exhibited the highest activity against S.epidermis sp. and Br. abortus, respectively. In addition, all unsymmetrical diimines are showed high antifungal activity against C. albicans. © 2020 by SPC (Sami Publishing Company)Öğe Synthesis of novel polymers containing Schiff base as potential antimutagenic and antimicrobial agents(Sami Publishing Company, 2020) Nartop, D.; Tokmak, E.; Özkan, E. H.; Kızıl, H. E.; Öğütcü, H.; Ağar, G.; Allı, S.In this research study, two novel polymers including Schiff base were prepared by condensation reaction of polystyrene-A-NH2 with 5-nitro-2-thiophenecarboxaldehyde/or 5-(2-nitrophenyl)-2-furancarboxaldehyde. The synthesized polymers were evaluated using the elemental analysis, infrared spectroscopy (IR), gel permeation chromatography (GPC), thermal gravimetric analysis (TG/DTA). In addition, the antimicrobial and antimutagenic study of the polymers were reported. The antibacterial and antifungal activity were investigated using the diffusion method against pathogenic bacterial strains. PA-TC and PA-FC polymers exhibited the highest antimicrobial activity against the S. typhi H. and P. vulgaris, respectively. PA-FC polymer revealed the highest antifungal activity against C. albicans. The antimutagenic effects were evaluated using the sister chromatid exchange (SCE) and micronucleus (MN) methods against the sodium azide (NaN3) in human lymphocyte cells. The results demonstrated that the PA-FC polymer have strong antimutagenic properties, especially in the concentration of 20 µg/mL. © 2020 by SPC (Sami Publishing Company)
