Özet

Objectives: The development of antimicrobial molecules discussed with considerable achievement over the past decades provided many classes of semisynthetic or synthetic compounds. Resistance to many antimicrobial agents requires the discovery of novel molecules.

Materials and Methods: In this study, ten ethylparaben hydrazide-hydrazone derivatives, the previously reported, were evaluated for their in vitro antibacterial and antifungal activities. The microbroth dilution method was used for the determination of the minimum inhibitory concentration (MIC) values of the novel molecules.

Results: The antimicrobial activities of the molecules were found in a wide range with MIC values of 2-256 μg/mL. The synthesized compounds showed good to moderate antimicrobial activity compared with the standards. Among the synthesized molecules, compound 3g showed the best antimicrobial activity at 2 μg/mL against Staphylococcus aureus strain (ATCC 29213).

Conclusion: Ethylparaben hydrazide-hydrazone compounds in our study were found to have antimicrobial activities. Ethylparaben is currently used as an antibacterial agent and preservative for preparations. These studies are necessary since they detect the relationship between the substitutions and activity.
