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
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

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
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
Xiao Tao et al.
Science (New York, N.Y.), 326(5960), 1668-1674 (2009-12-19)
Inward-rectifier potassium (K+) channels conduct K+ ions most efficiently in one direction, into the cell. Kir2 channels control the resting membrane voltage in many electrically excitable cells, and heritable mutations cause periodic paralysis and cardiac arrhythmia. We present the crystal
