2-((4-R-5-R1-4H-1,2,4-TRİAZOL-3-İL)TİYO)ASETALDEHİTLERİN İLİDENHİDRAZİDLERİNİN SENTEZİ, ANTİMİKROBİYAL VE ANTİFUNGAL AKTİVİTESİ

Amaç: Bu çalışmanın amacı, 2-(4-R-5-R1-4H-1,2,4-triazol-3-yl)tio)asetaldehitlerin bir dizi ilidenhidrazidinin sentezi ve antimikrobiyal ve antifungal özelliklerinin yapı-etki ilişkisi kurularak incelenmesidir. Gereç ve Yöntem: Antimikrobiyal ve antifungal aktivitenin tespiti, aşağıdaki mikroorganizma türleri için disk-difüzyon yöntemi ile gerçekleştirilmiştir: Corynebacterium pseudodiphtheriticum, Pseudomonas aeruginosa, Enterococcus faecalis, Proteus vulgaris, Escherichia coli, Salmonella spp., Staphylococcus saprophyticus, Staphylococcus aureus, Streptococcus pyogenes, Candida.Sonuç ve Tartışma: Yeni 2-((4-R-5-R1-4H-1,2,4-triazol-3-yl)tio)asetaldehitlerin ilidenhidrazidleri sentezlenmiştir. Yapıları modern analiz yöntemleri olan IR, 1H spektroskopisi, element analizi ve GS\MS yöntemi ile doğrulanmıştır. Sentezlenen 13 bileşik için antimikrobiyal aktivite, 3 farklı konsantrasyonda (0.1; 0.2; % 0.5) 10 mikroorganizma suşu üzerinde çalışılmıştır. Çalışmanın sonuçlarına göre, bazı yapı-etki ilişkileri kurulmuştur. Elde edilen sonuçlar, belirgin antibakteriyel etkiye sahip bileşikler için hedeflenen araştırmanın temelini oluşturabilir. Test maddelerinin konsantrasyonunun artırılmasının, neredeyse tüm durumlarda antimikrobiyal etkiyi artıracağı tahmin edilmektedir. Çalışmamızdaki en aktif bileşik N'-(2-((5-metil-4H-1,2,4-triazol-3-il)tiyo)etiliden)-4-nitrobenzohidrazid 3i’dir (ZOI Sta.s. ve Sp. - 25 ve 26 mm % 0,5 konsantrasyonda).
