Abstract:

A new series of 2-aryliden-hydrazone-thiazoles 3a-l was synthesized starting from aryliden-thiosemicarbazones by the Hantzsch condensations with different α (or γ)- halocarbonyl compounds. The newly synthesized compounds were screened for their antimicrobial activity against 4 bacterial strains: Staphylococcus aureus (ATCC 29213), Bacillus subtilis (ATCC 60511), Escherichia coli (ATCC 25922), Pseudomonas aeruginosa
(ATCC 10145) and one fungal strain: Candida albicans (ATCC 10231). The compounds 3i and 3j demonstrated a good inhibitory activity against E. coli. The results of the antifungal screening showed that the compounds 3a-d and 3f-j presented an excellent activity against Candida albicans.
