L-162782
L-162782 is a high affinity AT1 receptor ligand for rat and human wild-type AT1 with IC50 values of 28.5 and 24.6 nM, respectively. L-162782 acts as a partial agonist (EC50 ≈ 30 nM) and insurmountable antagonist (IC50 = 6.5 μM) on wild-type rat AT1 receptors in COS-7 cells. L-162782 reduces Angiotensin II (HY-13948)-induced phosphatidylinositol turnover. L-162782 can be used for hypertension research.

L-162782 binds with high affinity to wild-type rat and human AT1 receptors, with binding selectively impaired by the A104V mutation in human AT1 receptor (20-fold reduction in affinity)[1].
L-162782 acts as a partial agonist (stimulating phosphatidylinositol turnover to 64% of Angiotensin II response) and antagonist on wild-type rat AT1 receptors in COS-7 cells[1].
L-162782 binds with unaltered high affinity to N295D mutant rat AT1 receptors but has impaired agonistic efficacy (stimulating turnover to 19.4% of Angiotensin II response) and acts as an antagonist with an IC50 of 90-180 nM[2].
