(A) Inhibitory activity of compound 9 on tyrosinase (IC50: 9.8 ± 0.9 μM; kojic acid =19.5 ± 1.5 μM). (B) Relationship of the hydrolytic activity of tyrosinase with enzyme concentration at a variety of inhibitor concentration. (C) Lineweaver–Burk plot (Competitive type) and (D) Dixon plot (Ki: 5.8 ± 0.9 μM) for the inhibition of compound 9.
