BIBO 3304

Research use only, not for human use.

BIBO 3304 is a potent, selective, nonpeptide neuropeptide Y Y1 receptor antagonist with IC50 of 0.38 and 0.72 nM for human and the rat Y1 receptor, respectively.

BIBO 3304 is a potent, selective, nonpeptide neuropeptide Y Y1 receptor antagonist with IC50 of 0.38 and 0.72 nM for human and the rat Y1 receptor, respectively; shows low affinity for the human Y2 receptor, human and rat Y4 receptor, human and rat Y5 receptor (IC50>1,000 nM); inhibits the feeding response induced by 1 mg NPY in mice, also completely abolishes PYY-induced inhibition of insulin release in vivo.Obesity Discontinued(In Vivo):BIBO3304 TFA (30 μg; bilateral paraventricular nucleus injection) attenuates the hyperphagia following fasting.BIBO3304 TFA (15-60 μg) dose-dependently inhibits the feeding reponse mediated by 1 μg NPY.BIBO3304 TFA (0.5 μM; p.o.) significantly increases serum insulin levels.
