Natural products as tyrosinase inhibitors.

Tyrosinase is a crucial copper-containing enzyme involved in the production of melanin. Melasma, age spots, and freckles are examples of hyperpigmentation diseases caused by excess production of melanin. Inhibiting tyrosinase activity is a crucial method for treating these disorders along with various applications such as cosmetics, food technology, and medicine. Natural products have proven a rich source of tyrosinase inhibitors, with several molecules from plant, marine, and microbial sources showing potential inhibitory action. This chapter provides a complete overview of natural compounds that have been found as tyrosinase inhibitors, with emphasis on their structures, modes of action, and prospective applications.
