γ-Hydroxybutyric acid (GHB) is a neuroactive substance with specific high-affinity binding sites. To facilitate target identification and ligand optimization, we herein report a comprehensive structure-affinity relationship study for novel ligands targeting these binding sites. A molecular hybridization strategy was used based on the conformationally restricted 3-hydroxycyclopent-1-enecarboxylic acid (HOCPCA) and the linear GHB analog trans-4-hydroxycrotonic acid (T-HCA). In general, all structural modifications performed on HOCPCA led to reduced affinity. In contrast, introduction of diaromatic substituents into the 4-position of T-HCA led to high-affinity analogs (medium nanomolar Ki) for the GHB high-affinity binding sites as the most high-affinity analogs reported to date. The SAR data formed the basis for a three-dimensional pharmacophore model for GHB ligands, which identified molecular features important for high-affinity binding, with high predictive validity. These findings will be valuable in the further processes of both target characterization and ligand identification for the high-affinity GHB binding sites.

Enantiomerically pure alkyl 3-oxocyclohexanecarboxylates and the corresponding alcohols have been prepared using HLAD as a suitable catalyst.Kinetic and thermodynamic parameters for the enzymatic reductions are given.The enantiomeric purity and the absolute configuration of the reaction products are determined.The alcohol moiety (methyl, isopropyl or pentyl) of the ester group influences both the steric course and the kinetics of the reduction.Side reactions of the substrate with the reaction medium can be avoided by an appropriate choice of the reaction conditions.
