BIBO 3304 trifluoroacetate is a high affinity NPY Y1 receptor antagonist (IC50 values are 0.38 and 0.72 nM at human and rat receptors respectively) that displays > 2600-fold selectivity over Y2, Y4 and Y5 receptors. Inhibits NPY- and fasting-induced feeding in vivo following central administration. Also antagonizes anxiolytic-like effects of NPY.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
