生物活性
产品描述 |
一种内皮素 (ET) 受体的一个拮抗剂,其对 ETA 和 ETB 受体的 pA2 值分别为 9.5,7.7。 |
|
靶点 |
ETA 9.5 (pA2) |
ETB |
体外研究 |
Affinity of Tezosentan for the ET receptors is assessed in different cells and tissues.Tezosentan inhibits the specific 125Ilabeled ET-1 binding to ETA receptors with an inhibitory potency (Ki) of 0.3nM on CHO cells and of 18nM 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 21nM.Tezosentan up to a concentration of 1μM 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 (1μM) induces a weak inhibition of less than 20%. |
|
体内研究 |
In pithed Wistar rats,Tezosentan dose-dependently inhibits the pressor effect of big ET-1 (P<0.001 at all doses). At the lowest dose tested of 1mg/kg,Tezosentan inhibits the pressor effect of the various doses of big ET-1 by 50 to 80%.Tezosentan has no effect by itself on blood pressure in these pithed rats.Tezosentan is very effective in a rat model of acute renal failure.ET antagonists have been shown to prevent the vasoconstriction and the renal failure that follow acute renal ischemia in rats. |
推荐实验方法(仅供参考)
动物实验: |
|
Rats 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 10mg/kg 1h and 20 min before glycerol.Rats are allowed to recover for 2h and then are placed in individual metabolic cages for 48h.Blood samples withdraw from a catheter placed in the abdominal aorta and urine free of food and feces are collected at 24 and 48h.Plasma and urinary creatinine levels are measured with a centrifugal analyzer.Renal function is assessed by calculating creatinine clearance at 24 and 48h after glycerol administration. |
