control kojic acid. Herein, we report the synthesis of further series of 4‐(4‐fluorobenzyl)piperazin‐1‐yl analogues bearing a (hetero)aromatic fragment as key feature to improve protein affinity. The newly synthesized compounds were assayed in vitro and proved to be potent inhibitors in the low‐micromolar range. The active 2‐thienyl and 2‐furyl derivatives were selected for further modification to
