[3H]A81988 binds with high affinity (KD=0.57 nM) and the KD determined from kinetics assays is similar.Hydrocortisone Autophagy Non-specific binding (defined with 1 μM angiotensin-II) is very low (In Vivo:|To verify this hypothesis, B2-/- or wild-type mice (B2+/+) are administered a nonpeptide antagonist of Ang II type 1 (AT1) receptors (A81988) from conception through 180 days of age.PMID:34910849 Untreated B2+/+ and B2-/- served as controls. Blood pressure (BP) and heart rate are monitored with the use of tail-cuff plethysmography at regular intervals. Ventricular weights, diameters, wall thickness, chamber volume, and myocardial fibrosis are measured at 40 and 180 days. No differences are observed in BP, heart rate, and cardiac weight and dimensions between treated and untreated B2+/+. The BP of AT1 antagonist-treated B2-/- is reduced until 70 days; then, it increases to the levels found in untreated B2-/-. AT1 receptor blockade results in a reduction in left ventricular mass, chamber volume, and wall thickness and abrogated myocardial fibrosis in B2-/-. A81988 (A-81988) decreases the BP of Bk2r-/- either in normosodic conditions or after sodium deprivation, whereas in Bk2r+/+ it produces a modest decrease under hyposodic conditions only.|Products are for research use only.
