Barbadin is a novel and selective β-arrestin/β2-adaptin interaction inhibitor, has IC 50 values of 19.1?μM for β-arrestin1 and 15.6?μM for β-arrestin2. Barbadin blocks agonist-promoted endocytosis of the prototypical β2-adrenergic, V2-vasopressin and angiotensin-II type-1 receptors. Barbadin can induce apoptosis.
Barbadin (4 h) treatment reduces cell viability and induces apoptosis.Barbadin (2 h) treatment arrests breast cancer cells in G0/G1 phase. has not independently confirmed the accuracy of these methods. They are for reference only.Apoptosis Analysis
