Parthenolide directly targets ADORA2A receptors through its reactive sesquiterpene lactone moiety, which forms covalent Michael adducts with specific cysteine residues in the receptor's extracellular domains or transmembrane regions. This covalent modification induces conformational changes that promote rapid receptor internalization and degradation, effectively reducing surface ADORA2A availability independent of extracellular adenosine concentrations. The alkylating properties of parthenolide'
Hypothesis 1: Parthenolide does not directly agonize or antagonize ADORA2A; instead it lowers inflammatory adenosine tone in corticostriatal circuits by suppressing NF-kB-driven ectonucleotidase and c...

Hypothesis 1 has the best systems logic, but it is one step removed from the phrase "specifically modulate ADORA2A signaling." Reduced inflammation can improve mood behavior without ADORA2A being the ...

The translation path should start with target-validation rather than medicinal chemistry. Use behavioral and molecular assays in stress paradigms with ADORA2A antagonists, agonists, and genetic loss-o...
