Abstract
Tyrosinase is a type 3 copper protein involved in the biosynthesis of melanin pigments, therefore the inhibition of its enzymatic activity represents a promising strategy for the treatment of hyperpigmentation-related disorders. To address this point at issue we have previously designed a class of 4-(4-fluorobenzyl)piperazin-1-yl-based compounds proving to be more active inhibitor against tyrosinase from mushroom Agaricus bisporus when compared to positive control kojic acid. Herein, we report the synthesis of further series of 4-(4-fluorobenzyl)piperazin-1-yl-analogs bearing a (hetero)aromatic fragment as key feature to improve protein affinity. The new synthesized compounds were in vitro assayed proving to be potent inhibitors in low micromolar range. Then, the active 2-thienyl and 2-furyl derivatives were selected for further modifications considering their binding mode analyzed by docking studies and their satisfactory safety profiles.File | Dimensione | Formato | |
