With the aim to find out structural features for the tyrosinase inhibitory activity, in the present communication we report the synthesis and pharmacological evaluation of a new series of phenylcoumarin derivatives with different number of hydroxyl or ether groups and bromo substituent in the scaffold. The synthesized compounds 5-12 were evaluated as mushroom tyrosinase inhibitors showing, two of them, lower IC50 than the umbelliferone. Compound 12 (IC50 = 215 mu M) is the best tyrosinase inhibitor of this series. (C) 2011 Elsevier Ltd. All rights reserved.
