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 (A 2AR). 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 A 2AR, 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. Above and beyond: Insight into the binding kinetics of ZM241385 derivatives at the human adenosine A2A receptor has provided additional information beyond a traditional structure-activity relationship (SAR) analysis. The strategy, combining a structure-kinetics relationship investigation and SAR, can serve as an important tool for more directed medicinal chemistry efforts in the future.

An electrostatic interaction related to a favorable position of the distal phenyl ring and a phenylalanine residue in the binding pocket would explain the higher 5-HT1A affinity of a 4-phenyl-1,2,3,6-tetrahydropyridine (THP) analogue compared t

A small molecule library of piperazinylalkylisoxazole derivatives containing about 600 compounds was designed, synthesized and evaluated for blocking effects on T-type Ca2+ channel. Several ligands were identified to possess high inhibitory activity against the T-type Ca 2+ channel. The compound 21 with trifluoromethyl substituents at C3-position of phenyl group (R1) and C2- position of phenyl group (R2) showed the highest inhibitory activity with IC50 value of 1.02μM, which is comparable to that of mibefradil.
