Abyssinone affects multiple macromolecular processes in a concentration-dependent manner, 12.5 µg/mL (□), 100 µg/mL (■). The activities of respective macromolecular processes with control antibiotics were as follows: 0.8 µg/mL tetracycline (protein, 46±1.2), 0.06 µg/mL rifampicin (RNA, 18.5±2.6), 0.8 µg/mL ciprofloxacin (DNA, 52±5.2).
