Biochem/physiol Actions

Gs-biased, β2 subtype-selective adrenergic receptor (AR) negative allosteric modulator (NAM) that inhibits β-arrestin recruitment, but not Gs coupling to β2AR.

DFPQ is a Gs-biased, β2 subtype-selective adrenergic receptor (AR) negative allosteric modulator (NAM) that inhibits β-arrestin recruitment (IC50 = 600 nM; 30-min DFPQ pretreatment prior to 12-min 1 μM ISO induction), but not Gs coupling to β2AR (30-min 10 μM DFPQ pretreatment prior to 10-min 1 μM ISO-induced cAMP production). DFPQ effectively inhibits agonist-induced β2AR phosphorylation (IC50 = 2.6 μM; 30-min DFPQ pretreatment prior to 10-min 1 μM ISO induction) and internalization (100% inhibition by 30-min 10 μM DFPQ prior to 1h 10 μM ISO) and protects against the functional desensitization of β-agonist-mediated regulation in cell and tissue models with minimal effects on β1AR.
