Screening of anti-S. aureus activity of 20 compounds. Newly synthesized compounds (20 μg) were tested for their individual activity against S. aureus (ATCC 25923) by using a disc fusion assay. Representative images from n = 3 are shown. The zone of inhibition (mm) was measured and is listed in Table 1. DMSO and Disc were used as negative controls. Agar plates were photographed and one of the representative images from n = 5 were processed in Adobe Illustrator CS6 (v16.0.0, Adobe Systems Inc., USA).
