A P Davenport et al.
Journal of cardiovascular pharmacology, 22 Suppl 8, S22-S25 (1993-01-01)
Our aim was to characterize and determine the function of endothelin (ET) receptor subtypes in human vascular tissue. Reverse transcriptase-polymerase chain reaction with nested oligonucleotide primers detected the presence of mRNA encoding both ETA and ETB receptors in the media
M Ihara et al.
Life sciences, 51(6), PL47-PL52 (1992-01-01)
A linear endothelin (ET) analog, N-acetyl-LeuMetAspLysGluAlaValTyrPheAlaHisLeu-AspIleIleTrp (BQ-3020), is highly selective for ETB receptors. BQ-3020 displaces [125I]ET-1 binding to ETB receptors (nonselective to ET isopeptides) in porcine cerebellar membranes (IC50: 0.2nM) at a concentration 4,700 times lower than that to ETA
U Ekelund et al.
British journal of pharmacology, 112(3), 887-894 (1994-07-01)
1. This paper describes, in quantitative terms, the in vivo effects of two selective ETB-receptor agonists (IRL 1620 and BQ 3020) on vascular resistance (tone) in the following consecutive sections of the vascular bed of sympathectomized cat skeletal muscle: large-bore
Phuong N Quang et al.
Pain, 149(2), 254-262 (2010-03-09)
Endothelin-1 (ET-1) produced by various cancers is known to be responsible for inducing pain. While ET-1 binding to ETAR on peripheral nerves clearly mediates nociception, effects from binding to ETBR are less clear. The present study assessed the effects of
Peter Johnström et al.
Experimental biology and medicine (Maywood, N.J.), 231(6), 736-740 (2006-06-03)
The endothelin (ET) receptor system has been shown to play a role in a number of vascular diseases. We have synthesized 18F-and 11C-labeled radioligands to enable in vivo imaging of the fundamental processes involved in ET receptor pharmacology in normal
