BIIE 0246 is a potent and selective antagonist of neuropeptide Y Y2 receptor with IC50 value of 3.3 nM [1].

Neuropeptide Y Y2 receptor (Y2R) is a G-protein-coupled receptor for neuropeptide Y (NPY), which is widely distributed in the peripheral and central nervous system. Y2R mediates the presynaptic inhibitory effect [2].

BIIE 0246 is a potent and selective Y2R antagonist. In rat hippocampal slices, BIIE0246 (100 nM) suppressed the inhibition of primary afterdischarge activity induced by NPY and [ahx5-24]NPY. Also, BIIE0246 suppressed the inhibitory effects of NPY and [ahx5-24]NPY, which inhibited the population excitatory postsynaptic potential (pEPSP) evoked by stratum radiatum stimulation in area CA1 [2]. In HEK293 cells transfected with the rat Y2 receptor, BIIE0246 exhibited high affinity for specific PYY3-36 binding sites with Ki values of 8-15 nM. In the rat colon, BIIE0246 (1 μM) completely blocked PYY3-36-induced contraction response [3].

In rats, BIIE0246 (1 nM) attenuated the reduction in feeding induced by PYY(3-36) (7.5 nmol/kg). In satiated rats, BIIE0246 significantly increased feeding. These results suggested that Y2R played a critical role in post-prandial satiety [4]. In the elevated plus-maze, BIIE0246 exhibited anxiolytic-like effect [5].
