The binding thermodynamics of the stereoisomers of fenoterol, (R,R')-, (S,S')- , (R,S')-, and (S,R')-fenoterol, to the β2-adrenergic receptor (β2-AR) have been determined. The experiments utilized membranes obtained from HEK cells stably transfected with cDNA encoding human β2-AR. Competitive displacement studies using [3H]CGP-12177 as the marker ligand were conducted at 4°, 15°, 25°, 30° and 37°C, the binding affinities calculated and the standard enthalpic (ΔH°) and standard entropic (ΔS°) contribution to t…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
