Biological Activity

LY-2940094 is a potent, selective and orally available antagonist of nociceptin receptor (NOP receptor) with Ki of 0.105 nM and Kb of 0.166 nM. LY2940094 (3, 10, or 30 mg/kg; 2-3 mL/kg; orally daily; for 4 days) dose-dependently reduces homecage ethanol self-administration in Indiana Alcohol-Preferring (P) and Marchigian Sardinian Alcohol-Preferring (msP) rats, without affecting food/water intake or locomotor activity. LY-2940094 reduces ethanol self-administration in animal models. Furthermore, LY2940094 blocked ethanol-stimulated dopamine release in response to ethanol challenge (1.1 g/kg, IP).

Animal Experiment
Animal models Female Alcohol-Preferring (P) rats (250-320 g); Male Marchigian Sardinian Alcohol-Preferring (msP) rats (400-450 g)
Formulation dissolved in 20% Captisol in 25 mM phosphate buffer (pH 3, adjusted for L-tartaric acid salt weight)
Dosages 3, 10, or 30 mg/kg; 2-3 mL/kg
Administration 4 daily orally administered

Km factor 3 6 12 8 5 20
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.
