B0AT2, encoded by the SLC6A15 gene, is a transporter for neutral amino acids that has recently been implicated in mood and metabolic disorders. It is predominantly expressed in the brain but little is otherwise known about its function. In order to identify inhibitors for this transporter we screened a library of different 3133 bioactive compounds. Loratadine, a clinically used histamine H1 receptor antagonist, was identified as a selective inhibitor of B0AT2 with an IC50 of 4 μM while being less active or inactive against several other members of the SLC6 family. Reversible inhibition of B0AT2 was confirmed by electrophysiology. A series of loratadine analogs was synthesized to get insight into the structure-activity relationships. Our studies provide the first chemical tool for B0AT2.
