Research Question¶
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.
