PD 123319 ditrifluoroacetate

PD 123319 ditrifluoroacetate is a potent, selective, non-peptide angiotensin AT2 receptor antagonist with IC50 values of 34 and 210 nM in rat adrenal tissue and brain respectively. PD 123319 ditrifluoroacetate prevents the binding of angiotensin II to the receptor, which blocks signal transduction and causes vasodilation. Intravenous administration of PD 123319 to conscious hypertensive rats elicited an immediate dose-dependent increase in MAP that was sustained for approximately 7.4 min with 3 mg/kg PD123319.
