Abstract
Classical drug design and development rely mostly on affinity‐ or potency‐driven structure–activity relationships (SAR). Thus far, a given compound’s binding kinetics have been largely ignored, the importance of which is now being increasingly recognized. In the present study, we performed an extensive structure–kinetics relationship (SKR) study in addition to a traditional SAR analysis at the adenosine A2A receptor (A2AR). The ensemble of 24 A2AR compounds, all triazolotriazine derivatives resembling the prototypic antagonist ZM241385 (4‐(2‐((7‐amino‐2‐(furan‐2‐yl)‐[1,2,4]triazolo[1,5‐a][1,3,5]triazin‐5‐yl)amino)ethyl)phenol), displayed only minor differences in affinity, although they varied substantially in their dissociation rates from the receptor. We believe that such a combination of SKR and SAR analyses, as we have done with the A2AR, will have general importance for the superfamily of G protein‐coupled receptors, as it can serve as a new strategy to tailor the interaction between ligand and receptor.
