The inhibition of tyrosinase (Ty, EC 1.14.18.1) represents an efficient strategy of decreasing melanogenesis and skin hyperpigmentation. A combination of crystallographic and docking studies on two different tyrosinases, that from Bacillus megaterium (TyBm) and that from a mushroom (TyM), has contributed to increasing our knowledge about their structural information and translating that information to the most druggable human Ty (TyH) isozyme. In particular, we designed and synthesized a series of 1-(4-fluorobenzyl)piperazine and 1-(4-fluorobenzyl)piperidine derivatives showing inhibitory activities on TyM at micromolar ranges and more potency than that of the reference compound, kojic acid. The crystal structures of TyBm with inhibitor 3 (IC50 value of 25.11 mu M) and 16 (IC50 value of 5.25 mu M) were solved, confirming the binding poses hypothesized by in silico studies and revealing the main molecular determinants for the binding recognition of the inhibitors.
