Fig. 4From: Design, synthesis, and biological evaluation of symmetrical azine derivatives as novel tyrosinase inhibitorsThe binding orientation (a) and interactions (b) of compound 3f into the tyrosinase enzyme. Ligand 3f is displayed as cyan sticks, while the core residues are shown as green sticks. Hydrogen bonding, electrostatic, Pi–Pi, and alkyl-Pi interactions are displayed as green, orange, pink and light pink, respectivelyBack to article page
