Community-associated methicillin resistant Staphylococcus aureus (CA-MRSA) has become a severe health concern because of its treatment difficulties. Herein, we report the synthesis and biological evaluation of two phenazine natural products and a series of phenazines that show promising activities against MRSA with MIC values in the low micromolar range. Basic studies revealed that these compounds are bacteriostatic agents. The most active compound also displayed promising IC50 values against HaCat cells. Finally, a QSAR model was developed to understand the key structural features of the molecules.
