SB209670 is a nonpeptide synthetic compound that acts as a potent and specific antagonist of endothelin A (ET-A) and B (ET-B) receptors. Intravenous or intraduodenal administration of SB209670 can produce concentration-dependent inhibition of ET-1-mediated vasoconstriction in isolated vascular tissues. Studies on hypertensive rats show that SB209670 produces a dose-dependent decrease in blood pressure. In a gerbil stroke model SB209670 is protective in ischemia-induced neuronal degeneration. Thus, SB209670 can be used as a useful tool in characterizing and classifying the physiological and pathophysiological roles of Endothelin receptors1.ET-A receptors are predominantly expressed in peripheral tissues, especially in vascular smooth muscle tissues where they mediate vasoconstriction. They are also present in several different regions of the brain. ET-B receptors play an important role in regulating renal function and blood pressure and are expressed in sensory nerves. They are mainly present in medium- and large-sized cell bodies of human trigeminal ganglia.ET-A receptor has high affinity for endothelin-1 and endothelin-2 and relatively low affinity for endothelin-3, while the ET-B receptor has high affinity equally for all endothelin isopeptides2,3.

C29H28O9.

0.2-20 nM.

SB209670 is a potent mixed antagonist of ET-A and ET-B Endothelin receptors, shown to inhibit Endothelin-1 radioligand binding to human ET-A and ET-B with Ki of 0.2 nM and 18 nM, respectively. SB209670 inhibits Endothelin-1-evoked vasoconstriction in isolated vascular tissues in vitro, and is orally bioavailable and active in vivo1.
