Description: MK5046 is a novel bombesin receptor subtype-3 agonist. MK5046 effectively reduced body weight in rats and caused modest increases in body temperature, heart rate, and blood pressure. MK-5046 is the first BRS-3 agonist with properties suitable for use in larger mammals. In dogs, MK-5046 treatment produced statistically significant and persistent weight loss, which was initially accompanied by increases in body temperature and heart rate that abated with continued dosing. MK-5046 may be useful for treatment of obesity.
