N-Terminal myristoylation facilitates membrane binding and activity of proteins, in particular of Src family kinases, but the underlying mechanisms are only beginning to be understood. The chaperones UNC119A/B regulate the cellular distribution and signal

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 series of substituted 4-aryl-piperazine-ethyl heteroarylcarboxamides were prepared and tested in in vitro radioligand binding studies. The presence of a quinoxaline has a favourable impact in terms of serotonin 5-HT1A versus dopamine D4.2 receptor selectivity. Compounds with a 3-CF3 group at the distal phenyl ring are the most effective in terms of affinity and selectivity for 5-HT1A versus D4.2 receptors. A 4-phenyl-1,2,3,6- tetrahydropyridine in place of the corresponding 4-phenyl-piperazine side chain is also favourable not only for the affinity for 5-HT1A and D4.2 receptors but also in some cases for α2A-adrenoceptors.

T-type calcium channel is one of therapeutic targets for the treatment of cardiovascular diseases and neuropathic pain. In this study, as a part of our ongoing efforts to develop potent T-type calcium channel blockers, we designed oxazole derivatives subs

A series of substituted hydroxyphenylureas was synthesized, the chemical structure of which was designed based on structures of natural antioxidants, vitamin E (α-tocopherol) and uric acid. They exhibited high inhibitory activity against lipid peroxidation. In order to gain an insight into the mechanism of the inhibition reaction, we analyzed their structure-activity relationships quantitatively. Electronic and steric effects of substituents on the phenolic hydroxyl group were shown to be of importance in governing the inhibitory potency. An increase in the electron donating property of substituents toward the phenolic hydroxyl group enhanced the antioxidative activity by the stabilization of an electron-deficient radical-type transition state. The steric shielding by ortho-substituents stabilized the phenoxy radicals formed following the transition state. Derivatives having the carboxyl group were only weakly active presumably because of an intermolecular ion-dipole interaction of the phenolic hydroxyl group with the carboxylate anion which could retard the formation of the transition state.
