The discovery of beta1-adrenoceptor (β-AR) ligands is viewed as an enormous demand for fighting ailments mediated by the receptor including cardiovascular diseases. Such pursuit is gravely challenged due to the lack of lead screening methods with high efficiency. This work developed a chromatographic method for pursuing β-AR ligand from the herbal extract by fusing epidermal growth factor receptor (EGFR) as a tag at its C-terminus to stably express the fusion receptor in E.

In this work, we synthesized the immobilized alpha 1A adrenergic receptor (α-AR), a GPCR subtype mediating smooth muscle contraction, through a site-selective covalent method that relies on the reaction between haloalkane dehalogenase tagged α-AR and macroporous silica gel coated with 6-chlorohexanoic acid. To investigate thermodynamic and extra-thermodynamic parameters for ligand binding, we utilized the covalently immobilized receptor as stationary phase to perform frontal analysis and injection-amount dependent analysis as well as compared with the random immobilization method.

To address such challenges, this work developed and characterized an approach to the rapid discovery of MR ligands using the immobilized receptor as the chromatographic stationary phase. We fused haloalkane dehalogenase (Halo) as a tag at the C-terminus of MR.
