Özet

In this work, we reported the synthesis and evaluation of antibacterial and antifungal activities of three new compound series obtained from 6-(phenyl/4-chlorophenyl) imidazo[2,1-b]thiazole-3-acetic acid hydrazide: 2-{[6-(phenyl/4-chlorophenyl) imidazo[2,1-b]thiazol-3-yl]acetyl}-N-alkyl/arylhydrazinecarbothioamides (2a-d), 4-alkyl/aryl-2,4-dihydro-5-{[6-(phenyl/4-chlorophenyl) imidazo[2,1-b] thiazol-3-yl] methyl}-3H-1,2,4-triazole-3-thiones (3a-n), and 2-alkyl/arylamino-5-{[6-(phenyl/4-chlorophenyl) imidazo[2,1-b] thiazol-3-yl] methyl}-1,3,4-thiadiazoles (4a-g). The newly synthesized compounds were characterized by IR, H-1 NMR, C-13 NMR (APT), mass and elemental analysis. Their antibacterial and antifungal activities were evaluated against Staphylococcus aureus ATCC 29213, Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Candida albicans ATCC 10231, C. parapsilosis ATCC 22019, C. krusei ATCC 6258, Trichophyton mentagrophytes var. erinacei NCPF 375, Microsporum gypseum NCPF 580, and T. tonsurans NCPF 245. 3c, 3f, 3m, 3n, and 4e showed the highest antibacterial activity. Particularly 3c, 3f, 3g, 3k, 3n, 4a, 4e, and 4g showed the highest antifungal activity against tested fungi.
