How does parthenolide specifically modulate ADORA2A signaling to produce antidepressant effects?

PARTIALLY ADDRESSED

While the study identifies ADORA2A as a key target through molecular docking and pharmacological validation, the specific mechanism by which parthenolide modulates ADORA2A signaling remains unclear. Understanding whether parthenolide acts as an agonist, antagonist, or allosteric modulator is critical for therapeutic development. Gap type: unexplained_observation Source paper: Parthenolide inhibits methamphetamine-induced depressive-like behavior by targeting ADORA2A. (2026, Phytomedicine : international journal of phytotherapy and phytopharmacology, PMID:41795299)
