All compounds were evaluated for in vitro antibacterial activity. Compounds April 12 2019 exhibited good to moderate antibacterial activity. Compound 3f Zone of Inhibition Accepted April 21 2019 µM was found to be the most active one and comparable to the standard Available online Streptomycin IC50 µM . The compounds having chloro substituent exhibit good April 22 2019 membrane damage property against Methicillin-resistant Staphylococcus aureus MRSA Keywords confirmed by SEM analysis. Structure-activity relationship SAR was rationalized by looking Schiff base Fluoroaniline at the varying structural features of the molecules. Antibacterial activity MRSA 2019 by the authors licensee Growing Science Canada. 1. Introduction Schiff bases imine or azomethine C N- are formed by condensation of precursors of amine and carbonyl groups1-2. These Schiff bases are having broad .
