There is a need for chemicals that are resistant to these diseases because the sensitivity of microorganisms that cause diseases in living beings to the drugs used against them is gradually decreasing. Therefore, new Fe(II) {[Fe(abt)2(SO4)].H2O (1) and [Fe(smabt)2(SO4)].H2O (2)} and Cu(II) {[Cu(abt)2(Ac)2].4H2O (3) and [Cu(abt)2(Ac)2].4H2O (4)} complexes of N-(benzothiazol-2-yl)benzamide (abt) and 4-chloro-N-(6-sulfamoylbenzothiazol-2-yl)benzamide (smabt) were synthesized. The structures of 1-4 were suggested by elemental analysis, AAS, IR, molar conductivity and magnetic susceptibility methods. As a result of spectroscopic evaluation, compounds 1-4 were suggested to be nonionic and have tetrahedral geometry. Additionally, the antimicrobial activities of all substances against C. albicans (yeast), E. faecalis, E. coli, L. monocytogenes, S. aureus, P. aeruginosa and B. subtilis (bacteria) were investigated and compared with Ketoconazole, Fluconazole, Levofloxacin, Chloramphenicol, Vancomycin and Cefepime. All substances were observed to have antimicrobial properties against bacteria or yeast. When the antimicrobial activities of the starting materials (abt, smabt) and complexes (1-4) were compared, the same activity was observed against S. aureus (except 4), E. coli (except 1), B. subtilis, E. faecalis, L. monocytogenes bacteria, and C. albicans yeast. 4 showed less activity in S. aureus bacteria, 1 showed more activity in E. coli bacteria. In P. aeruginosa bacteria, the following effects were observed: 1 > 3, smabt > abt, 2, 4.

N-(benzotiazol-2-il)benzamit türevlerinin Fe(II) ve Cu(II) Komplekslerinin Sentezi ve Karakterizasyonu

Öz

Canlılar üzerinde hastalıklara neden olan mikroorganizmaların karşı kullanılanilaçların duyarlılığı gitgide azalmasını nedeniyle bu hastalıklara karşı dirençbgösteren kimyasallara ihtiyaç bulunmaktadır. Bu nedenle, N-(benzotiazol-2-il)benzamit’in (abt) ve 4-kloro-N-(6-sülfamoilbenzotiazol-2-il)benzamit’in (smabt) yeni Fe(II) {[Fe(abt)2(SO4)].H2O (1) ve [Fe(smabt)2(SO4)].H2O (2)} ve Cu(II){[Cu(abt)2(Ac)2].4H2O (3) ve [Cu(smabt)2(Ac)2].4H2O (4)} kompleksleri sentezlendi. 1-4’ün yapıları, element analiz, AAS, IR, molar iletkenlik ve manyetik duyarlılık yöntemleri ile önerildi. Spektroskopik değerlendirmenin bir sonucu olarak, 1-4 bileşiklerinin iyonik olmayan ve tetrahedral geometriye sahip olduğu önerildi. Ayrıca, tüm maddelerin C. albicans (maya), E. faecalis, E. coli, L.monocytogenes, S. aureus, P. aeruginosa ve B. subtilis (bakteri) karşı antimikrobiyal aktiviteler incelendi ve Ketokonazol, Flukonazol, Levofloksasin, Kloramfenikol, Vankomisin ve Sefepim ile karşılaştırıldı. Tüm maddelerin bakterilere veya mayaya karşı antimikrobiyal özellik gösterdiği gözlendi. Başlangıç maddeleri (abt, smabt) ile komplekslerin (1-4) antimikrobiyal aktiviteleri karşılaştırıldığında, S. aureus (4 hariç), E. coli (1 hariç), B. subtilis, E. faecalis, L. monocytogenes bakterileri ve C. albicans mayasında aynı aktivite gözlenmiştir. S. aureus bakterisinde 4 daha az, E. coli bakterisinde 1 daha çok etki göstermiştir. P. aeruginosa bakterisinde ise 1 > 3, smabt > abt, 2, 4 şeklinde etki gözlenmiştir.
