Özet
Objective: Multidrug-resistant pathogenic bacteria, fungi, and Mycobacterium tuberculosis infections continue to be increasingly widespread worldwide.In organic chemistry, the tiya-Michael type addition is also significant reaction in the synthesis of bioactive compounds.In this study, the aim is to synthesize the series of new Michael type addition products 2-amino-3-[(2-nitro-1-phenylpropyl)thio]propanoic acid (IIa-IIg) and to investigate their in vitro, antibacterial, antifungal and antitubercular activity.Material and Method: IIa-IIg derivatives were performed combining β-methyl-β-nitrostyrenes (Ia-Ig) with L-cysteine using Michael addition reaction and characterized by 1 HNMR, FTIR, ESI-LC/MS and elemental analysis.Microdilution method and resazurin microtiter assay were used to determine antimicrobial activities.Result and Discussion: Comparing the activities of the synthesized compounds, IIa, IId and IIe were found to have significant activity, with a MIC value of 1.95 µg/ml, against Mycobacterium tuberculosis H37Rv strain.
