Compound <b>9</b> exhibited reversible competitive inhibitory activity against the enzyme tyrosinase, with an IC<sub>50</sub> value of 9.8 ± 0.9 µM. A molecular simulation revealed that compound <b>9</b> interacts via hydrogen bonding with residues His244, Thr261, and Val283 of tyrosinase. Additionally, compounds <b>3</b> and <b>7</b> were shown by half-leaf assays to exhibit inhibitory activity towards <i>Pepper mild mottle virus</i>.</p> Aloe vera;molecular docking;Pepper mild mottle virus;tyrosinase;Xanthorrhoeaceae 2016-10-25
