Tyrosinase-IN-44

Tyrosinase-IN-44 (Compound 3) is a tyrosinase inhibitor with IC50 values of 0.47 μM for monophenolase and 0.53 μM for diphenolase. It exhibits excellent glutathione peroxidase-like catalytic activity and DPPH radical scavenging activity. In banana and apple juice, Tyrosinase-IN-44 shows strong anti-browning activity by directly inhibiting polyphenol oxidase (PPO) and providing antioxidant effects. It is useful for redox regulation and food preservation.
