PD-156707
Based on 1 Customer Validation
PD-156707 is an orally active, nonpeptide and selective Endothelin-A receptor antagonist. PD-156707 binds to human ET-A and ET-B receptors with Ki values of 0.17 nM and 133.8 nM, respectively. PD-156707 shows reversal of established chronic hypoxic pulmonary hypertension in rats. PD-156707 can be used for the study of diseases associated with abnormal ET-A receptor activation, particularly pulmonary hypertension, stroke, and heart failure.

PD-156707 inhibits inositol phosphate production induced by ET-1 in Ltk cells (IC50 = 2.4 nM) and arachidonic acid release stimulated by ET-1 in rabbit renal artery VSMC cells (IC50 = 1.1 nM)[1].
PD-156707 (0.1-10 μM) cause a rightward shift in the concentration-response curve of ET-1-stimulated contraction of rabbit femoral artery[1].
PD-156707 (1 μM) exerts a significant inhibitory effect on spontaneous neointimal proliferation of transverse sections of human saphenous vein[1].

-
Animal Model:Male New Zealand White rabbits (2-3 kg)[2]
-
Dosage:0.003, 0.01, 0.03, 0.3 mg/kg/h
-
Administration:i.v. infusion, 1 h
-
Result:Showed dose-dependent inhibition of endothelin-1 (ET-1)-induced renal vascular resistance (RVR) increase.
Exerts no significant effect on baseline MAP, heart rate, RBF, or RVR.
Blocks ET-1-induced RVR increase without attenuating ET-1-induced MAP reduction.
