Affinity of Tezosentan for the ET receptors is assessed in different cells and tissues. Tezosentan inhibits the specific 125I-labeled ET-1 binding to ETA receptors with an inhibitory potency (Ki) of 0.3 nM on CHO cells and of 18 nM on membranes of baculovirus-infected insect cells. Similarly, Tezosentan inhibits the specific binding of 125I-labeled ET-1, ET-3, or sarafotoxin S6c to ETB receptors with an inhibitory affinity of 10 to 21 nM. Tezosentan up to a concentration of 1 μM did not exhibit any binding inhibitory activity in 27 radioligand binding assays different from ET binding. On H1 central, 5-hydroxytryptamine2A, and vasopressin V1 receptors, Tezosentan (1 μM) induces a weak inhibition of less than 20%[1].

Protocol
Rats[1]
A pseudocrush syndrome is simulated by injection of i.m. glycerol. A control group does not receive glycerol and is used as a reference. Tezosentan or bosentan for comparison or saline as control is injected as two bolus i.v. doses of 10 mg/kg 1 h and 20 min before glycerol. Rats are allowed to recover for 2 h and then are placed in individual metabolic cages for 48 h. Blood samples withdraw from a catheter placed in the abdominal aorta and urine free of food and feces are collected at 24 and 48 h. Plasma and urinary creatinine levels are measured with a centrifugal analyzer. Renal function is assessed by calculating creatinine clearance at 24 and 48 h after glycerol administration[1].
