The structures of obtained compounds (3a-e and 4a-e) were characterized using the spectroscopic methods (NMR, IR) and elemental analysis. Addition, the in vitro antimicrobial activities of compounds (3a-e) were tested against the five human pathogenic bacteria. Penicillin G and Ceftriaxone antibiotics were used as positive control. The results were given as MIC values (minimum inhibition concentration), and compounds 3b-d showed very high activity against Escherichia coli 111.
