BIIE 0246 is a selective non-peptide antagonist which binds to the neuropeptide NPY2-R in a competitive manner. In addition, BIIE 0246 suppresses another neuropeptide, [ahx5-24]NPY. Moreover, studies suggest that BIIE 0246 is highly lipophilic and as a result BIIE 0246 builds up at membranes near the receptors. Furthermore, studies indicate that the antagonistic effects of BIIE 0246 on neuropeptide Y (NPY) are insurmountable, which may result from the lipophilic nature of the antagonist.
