Academic Summary: Coffee is the most widely consumed beverage globally, and regular drinkers often show decreased mortality and protection against age-related diseases. This study reveals that brewed coffee and its major compounds—like caffeic acid, chlorogenic acid, and the diterpenoids kahweol and cafestrol—actively bind to a specific cellular receptor called NR4A1. By binding to this orphan nuclear receptor, these polyphenolics act as inverse agonists, successfully inhibiting the growth of NR4A1-responsive cancer cells. Ultimately, these findings suggest that the NR4A1 receptor functions as a nutrient sensor, playing a crucial role in how coffee delivers its remarkable health-protective and anti-aging benefits.
