Abstract
Allosteric ligands are promising drugs owing to their remote regulations of the orthosteric ligand signaling pathway. There are few allosteric ligands due to the lack of handy and efficacious method for the screening. Herein, we developed an affinity chromatographic method for allosteric ligand screening by immobilizing purified beta2 adrenoceptor (β2-AR) onto macroporous silica gel by a two-point tethering method. The method relies on the occupation of the orthosteric site by an antagonist and the chelation of N-terminal His-tag of the receptor and Ni2+ coated on the gel. The immobilized β2-AR demonstrated the greatest allosteric responsive feature when Cmpd-15 (0.25 μM) was included in the mobile phase. Under the same conditions, the association constants of three agonists (salbutamol, terbutaline, and tulobuterol) reduced to 47%, 19%, and 27% compared with the data without the inclusion of Cmpd-15 in the mobile phase. APF was screened as a potential allosteric modulator of β2-AR by applying the immobilized receptor in a natural product-derived DNA-encoded chemical library (DEL). Relying on these results, we reasoned that the current method has potential in screening allosteric ligands of the receptor. We expect that it is applicable for the discovery of new allosteric binding sites of a target protein and screening allosteric modulators of the other receptors from complex samples.

Abstract
Site-selective chemical modification of protein side chain has probed enormous opportunities in the fundamental understanding of cellular biology and therapeutic applications. Primarily, in the field of biopharmaceutical where formulation of bioconjugates is found to be potential medicine than an individual constituent. In this regard, Lysine and Cysteine are the most widely used endogenous amino acid for these purposes. Recently, the aromatic side chain residues (Trp, Tyr, and His) that are low abundant in protein have gained more attention in therapeutic applications due to their advantages of chemical reactivity and specificity. This review discusses the site-selective bioconjugation methods for aromatic side chains (Trp, Tyr and His) and highlights the developed strategies in the last three years, along with their applications. Also, the review highlights the prevalent methods published earlier. We have examined that metal-catalyzed and photocatalytic reactions are gaining more attention for bioconjugation, though their practical operation is under development. The review has been summarized with the future perspective of protein and peptide conjugations contemplating therapeutic applications and challenges.

Abstract
High-performance affinity chromatography is limited by its high cost and high pressure. Paper is made up of porous fiber networks and has the properties of low cost, ease of fabrication, and biodegradable. Due to these advantages, herein, we immobilized beta2-adrenoceptor (β2-AR) onto the surface of the polytetrafluoroethylene membrane, a paper-based material, and constructed a G protein-coupled receptor (GPCR)-in-paper chromatographic platform. This platform was characterized by Fourier transform infrared spectroscopy, fluorescence analysis, X-ray photoelectron spectroscopy, and chromatographic studies. These morphological and elemental analysis showed that β2-AR was successfully immobilized on the paper surface. The specific drugs have good retentions on the GPCR-in-paper chromatographic platform. The association constants of salbutamol, terbutaline and bambuterol to β2-AR were calculated to be 2.02 × 104 M-1, 1.15 × 104 M-1, 1.75 × 104 M-1 by adsorption energy distribution, which were in good line with the values from frontal analysis, zonal elution and previous literatures. We demonstrated that the GPCR-in-paper platform was cost-effective, easy to be modified for protein immobilization, and applicable in the receptor-drug interaction analysis. We believe such a platform sheds new light on paper chromatography for receptor-drug interaction analysis and other applications.

Abstract
Site-specific immobilization of proteins on a surface has been a long-lasting challenge in the fields of biosensing and biotechnology because of the need for improving the biological activity of immobilized protein via the maximal exposure of its bioactive domain. Herein, we reported a new site-specific immobilization method for His-tagged proteins onto a vinyl sulfone (VS)-bearing surface in a covalent manner. X-ray photoelectron spectroscopy characterization indicated the specificity of the addition reaction of the imidazole group in histidine on the VS-bearing surface at pH 7.0. Solution-based experiments were carried out to verify the reaction priority of the imidazole residue of histidine with the VS group at neutral conditions. The real-time immobilization process of two His-tagged proteins (HaloTag-6His and anti-HER2 Fab-6His) on surfaces presenting VS, preactivated carboxyl, and NTA groups were studied by quartz crystal microbalance. Compared to the existing methods utilizing covalent (NHS/EDC activated carboxyl) and coordinate (Ni2+-NTA) linking, our method offers two significant advantages for protein immobilization: high density and high specificity. The orientation of the two His-tagged proteins on the VS-bearing surface was confirmed by an enzyme-linked assay and an HER2+ liposome binding experiment. Our method of site-specific immobilization of His-tagged proteins is efficient and straightforward, which would be helpful to expand the applications of recombinant proteins in enzyme immobilization, biosensor and array fabrication, and drug delivery system.

Abstract
Traditional Chinese medicine (TCM) represents a valuable resource for lead compounds discovery. Given the complexity of TCM components, analytical methods play a key role in novel drug development. In our study, we established a high specific and reliable bio-active components screen system, where β2 adrenergic receptor (β2-AR) was immobilized on silica by non-covalent bonds and packed into a stainless steel column (4.6 × 50 mm, 7 μm) to form β2-AR chromatography column. The column was further coupled with high performance liquid chromatography-time of flight tandem mass spectrometry (TOF-MS/MS). By utilizing this strategy, we successfully identified four β2-AR-targeting compounds: tetrahydroberberine, tetrahydrocolumbamine, fumarine and corydaline from Corydalis Rhizome. The association constants between β2-AR and tetrahydroberberine (9.04 × 104/M) as well as fumarine (4.30 × 104/M) were determined by frontal chromatography. We also found that these two compounds shared the identical binding site on immobilized β2-AR with corresponding concentrations of 6.67 × 10-4 M and 5.88 × 10-4 M, respectively. The newly established method represents an efficient tool to identify the target specific natural compounds.

Abstract
The past decade has witnessed the great promise of strategies for ligand discovery based on surface-immobilized GPCRs. We present here a method for preparation of immobilized GPCRs. Key features include covalent immobilization with high specificity and robust application in drug-receptor interaction analysis and ligand screening. In our example assay using beta2-adrenergic receptor (β2-AR), the human DNA repair protein O6-alkylguanine-DNA alkyltransferase (hAGT) fusion receptor expressed in Escherichia coli was directly captured onto polyethylene glycol polyacrylamide (PEGA) resin. We observed even distribution and physiological functions of β2-AR on the resin. The immobilized β2-AR as a stationary phase enabled us to rapidly determine the binding of four drugs to β2-AR. By coupling this assay to mass spectrometry, we screened rosmarinic acid as a bioactive compound targeting β2-AR in Fructus Perillae. We concluded that O6-benzylguanine derivative-functionalized supporter is promising for specific immobilization of hAGT-tagged proteins; immobilized receptor chromatography has great potential in screening receptor-binding leads from herbal plants or traditional medicine recipes.

Abstract
The β2 adrenergic receptor (β2-AR) is a prototypical family A G protein-coupled receptor (GPCR) and an excellent model system for studying the mechanism of GPCR activation. Purified β2-AR was immobilized on macroporous silica gel to obtain liquid chromatographic stationary phase. The resulting phase was packed into a stainless steel column (4.6 × 50 mm, 7 μm) and used for on-line chromatographic system. When column oven temperature increased from 20.0 °C to 40.0 °C, uncomplete separate chromatographic peaks of ephedrine and pseudoephedrine as receptor conformational probe were gradually merged into one peak, meanwhile retention time and resolution of the probes were reduced correspondingly, which suggested that temperature could regulate protein conformation. Temperature-induced conformational change of immobilized β2-AR, especially changes at higher temperatures, indicated that constructed receptor chromatography could simulate fever disease state of human body and clarify receptor conformation change at pathological condition. At the same time this study could also provide new ideas for screening active components in pathological conditions.
