A series of novel compounds were synthesized and evaluated for their potential as DNA gyrase inhibitors and antimicrobial agents. Among them, compound 13a exhibited good antibacterial and antifungal activities.
A novel series of substituted 4,6-dimethyl-2-oxo-1-(thiazol-2-ylamino)-1,2-dihydropyridine-3-carbonitrile derivatives 6, 9, 13, 15, and 17 was synthesized in a good to excellent yield from the reaction of 1-(3-cyano-4,6-dimethyl-2-oxopyridin-1(2H)-yl)thiourea with 2-oxo-N'-arylpropanehydrazonoyl chloride, chloroacetone, alpha -bromoketones, ethyl chloroacetate, and 2,3-dichloroquinoxaline, respectively. The potential DNA gyrase inhibitory activity was examined using in silico molecular docking simulation. The novel thiazoles exhibit dock score values between - 6.4 and - 9.2 kcal/mol and they were screened for their antimicrobial activities. Compound 13a shown good antibacterial activities with MIC ranged from 93.7-46.9 mu g/mL, in addition, it shown good antifungal activities with MIC ranged from 7.8 and 5.8 mu g/mL.
