產品描述：

Prazosin-d8 is intended for use as an internal standard for the quantification of prazosin by GC- or LC-MS. Prazosin is an antagonist of α1-adrenergic receptors (α1-ARs).1,2 It selectively binds to α1-ARs with Ki values of 0.2, 0.25, and 0.32 nM for the human recombinant α1A-, α1B-, and α1D-ARs, respectively, over α2-ARs (Kis = 340 and 3.7 nM in α2A-AR-expressing HT-29 cells and α2B-AR-expressing NG108 cells, respectively).3,4 It also binds to melatonin receptor 3 (MT3) in hamster brain membranes (IC50 = 7.8 nM).5 Prazosin inhibits peripheral and central postsynaptic α1-ARs with IC50 values of 0.20 and 1.7 nM in isolated dog aorta and rat brain, respectively.1 It decreases diastolic blood pressure in normal, renal hypertensive, and spontaneously hypertensive rats when administered at a dose of 1 mg/kg.6 Prazosin (1.5 mg/kg) increases the number of entries and percentage of time spent in the open arms of the elevated plus maze, indicating anxiolytic-like activity, in alcohol-consuming rats and also reduces alcohol intake and alcohol-seeking behavior in alcohol-preferring rats.7,8|1.
