Background:

L 152804 is an orally active and selective neuropeptide Y Y5 receptor (NPY5-R) antagonist, with a Ki of 26 nM for hY5. L 152804 causes weight loss in diet-induced obese mice by modulating food intake and energy expenditure[1][2].

L 152804 displays >300-fold selectivity over hY1, hY2, and hY4 receptors[1].
