title: Synthesis and antimicrobial activity of 4-phenyl/cyclohexyl-5-(1-phenoxyethyl)-3-[N-(2-thiazolyl)acetamido]thio-4H-1,2,4-triazole derivatives.
abstract: The increasing clinical importance of drug-resistant fungal and bacterial pathogens has lent additional urgency to microbiological research and new antimicrobial compound development. For this purpose, new thiazole derivatives of triazoles were synthesized and evaluated for antifungal and antibacterial activity. The reaction of propionic acid hydrazides with various aryl/alkyl isothiocyanates gave thiosemicarbazides which furnished the mercaptotriazoles by alkali cyclization. The 4-phenyl/cyclohexyl-5-(1-phenoxyethyl)-3-[N-(2-thiazolyl)acetamido]thio-4H-1,2,4-triazole derivatives were synthesized by reacting the mercaptotriazoles with 2-chloro-N-(2-thiazolyl)acetamide. The chemical structures of the compounds were elucidated by IR, 1H-NMR, FAB+-MS spectral data. Their antimicrobial activities against Candida albicans (two strains), Candida glabrata, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa were investigated. The results showed that some of the compounds have very strong antifungal activity.
