Abstract
The clustered regularly interspaced short palindromic repeats (CRISPR) molecular system has emerged as a promising technology for the detection of nucleic acids. Herein, the development of a surface plasmon resonance (SPR) sensor that is functionalized with a layer of locally grown graphdiyne film, achieving excellent sensing performance when coupled with catalytically deactivated CRISPR-associated protein 9 (dCas9), is reported. dCas9 protein is immobilized on the sensor surface and complexed with a specific single-guide RNA, enabling the amplification-free detection of target sequences within genomic DNA. The sensor, termed CRISPR-SPR-Chip, is used to successfully analyze recombinant plasmids with only three-base mutations with a limit of detection as low as 1.3 fM. Real-time monitoring CRISPR-SPR-Chip is used to analyze clinical samples of patients with Duchenne muscular dystrophy with two exon deletions, which are detected without any pre-amplification step, yielding significantly positive results within 5 min. The ability of this novel CRISPR-empowered SPR (CRISPR-eSPR) sensing platform to rapidly, precisely, sensitively, and specifically detect a target gene sequence provides a new on-chip optic approach for clinical gene analysis.

Molecular mechanism and thermodynamic study of Rosuvastatin interaction with human serum albumin using a surface plasmon resonance method combined with a multi-spectroscopic, and molecular modeling approach. Eur J Pharm Sci 2021; 168:106005. [PMID: 34688823 DOI: 10.1016/j.ejps.2021.106005] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2021] [Revised: 09/01/2021] [Accepted: 09/08/2021] [Indexed: 11/18/2022]
Abstract
Rosuvastatin (ROS) is an anti-cholesterol drug belonging to statin drugs. A multi-spectroscopic approach combined with a molecular modeling technique was used to assess ROS association with human serum albumin (HSA). Besides, an HSA immobilized surface plasmon resonance (SPR) chip was used to obtain kinetic parameters (ka, kd, and KD). Fluorescence quenching titrations revealed that ROS interacts with HSA via a dynamic, exothermic, enthalpy-driven mechanism. Hydrogen bonds and van der Waals interactions as the most prevalent bonding forces contribute to ROS-HSA complex formation. ROS binding to HSA alters HSA conformation. The SPR results indicated that ROS and HSA have a strong interaction possessing an equilibrium constant (KD) of 1.55 × 10-8 M at 298 K. A competitive analysis of site markers showed that ROS has a higher tendency to bind to the warfarin binding site (site IIA), which may explain why warfarin has a higher anticoagulant effect in ROS users. FRET analysis indicated that non-radiation energy transfer occurred between ROS and HSA. According to molecular docking studies, ROS prefers binding sites IB and IIA while the ROS-HSA complex stabilizes due to the hydrogen bond and π-π interaction. The presence of hydrogen-bond donors and acceptors, as well as aromatic ROS moieties, facilitates such interactions.

Abstract
Amyloid-β 1-42 (Aβ1-42) aggregation is considered as an important process in the pathology of Alzheimer's disease (AD). Astaxanthin (ATX), a xanthophyll carotenoid, has a broad range of biological activities such as neuroprotective one. The present study aimed to elucidate the interaction of ATX with Aβ1-42, as well as its effect on Aβ1-42 aggregates under different conditions. Based on the surface plasmon resonance (SPR) results, ATX possessed a high affinity towards Aβ1-42 and the binding process was spontaneous, endothermic, and entropy-driven. Additionally, the binding affinity of ATX to Aβ1-42 was glucose and insulin concentration-dependent. Hydrophobic interactions may play an important role in the interaction between ATX and Aβ1-42. The results of SPR, thioflavin T (ThT), and transmission electron microscopy (TEM) analyses represented the dependency of the anti-amyloid activity of ATX on glucose, insulin, and ATX concentrations. Further, molecular docking results indicated the presence of some same binding sites on Aβ1-42 for ATX and glucose, as well as ATX and insulin, which suggests the possible competition between the molecules for Aβ1-42 binding. Furthermore, the MTT results confirmed that ATX effect on the viability of Aβ1-42-treated PC12 cells was dependent on glucose, insulin, and ATX concentrations. In general, the results provided further insights into the interaction between Aβ1-42 and ATX, as well as the effect of ATX on Aβ1-42 aggregates under various conditions.

Abstract
Albumin binding is the major cause for the toxicity of protein bound uremic toxins (PBUTs) in uremic patients. Albumin binding property is exploited to address this issue, as some of the extracorporeal dialysis systems use albumin as dialysate. In this line, a detailed study about binding of PBUTs to human serum albumin (HSA) and its domains gives valuable information. The focus of this work emphasizes the mechanism of binding of HSA and its domains with a few selected PBUTs such as hippuric acid (HA), indole acetic acid (IAA) and melatonin. The HSA domains (D2, D3 and D2-3) were expressed in Pichia pastoris and purified by using Albupure matrix. The binding of the expressed domains and HSA, with PBUTs, was measured using surface plasmon resonance and analyzed. All the three domains have significant affinity towards PBUTs, while D3 had greater affinity for all the three selected PBUTs. Docking studies showed that the basic amino acid, lysine, was forming hydrogen bond with PUBTs inorder to stabile these complex. This study would be having therapeutic importance for preparing the extracorporeal dialysis systems, in combination of different domains of HSA to remove the PBUTs.

Abstract
![]()
Introduction: Beta-Boswellic acid (BBA) is a pentacyclic terpene which has been obtained from frankincense and its beneficial effects on neurodegenerative disorders such as Alzheimer’s disease (AD) have been addressed.
Methods: In the present study, thermodynamic and kinetic aspects of BBA interaction with Tau protein as one of the important proteins involved in AD in the absence and presence of glucose has been investigated using surface plasmon resonance (SPR) method. Tau protein was immobilized onto the carboxy methyl dextran chip and its binding interactions with BBA were studied at physiological pH at various temperatures. Glucose interference with these interactions was also investigated.
Results: Results showed that BBA forms a stable complex with Tau (KD=8.45×10-7 M) at 298 K. Molecular modeling analysis showed a hydrophobic interaction between BBA and HVPGGG segment of R2 and R4 repeated domains of Tau.
Conclusion: The binding affinity increased by temperature enhancement, while it decreased significantly in the presence of glucose. Both association and dissociation of the BBA-Tau complex were accompanied with an entropic activation barrier; however, positive enthalpy and entropy changes revealed that hydrophobic bonding is the main force involved in the interaction.

Abstract
Traditional Chinese medicine (TCM), as a unique form of natural medicine, has been used in Chinese traditional therapeutic systems over two thousand years. Active components in Chinese herbal medicine are the material basis for the prevention and treatment of diseases. Research on drug-protein binding is one of the important contents in the study of early stage clinical pharmacokinetics of drugs. Plasma protein binding study has far-reaching influence on the pharmacokinetics and pharmacodynamics of drugs and helps to understand the basic rule of drug effects. It is important to study the binding characteristics of the active components in Chinese herbal medicine with plasma proteins for the medical science and modernization of TCM. This review summarizes the common analytical methods which are used to study the active herbal components-protein binding and gives the examples to illustrate their application. Rules and influence factors of the binding between different types of active herbal components and plasma proteins are summarized in the end. Finally, a suggestion on choosing the suitable technique for different types of active herbal components is provided, and the prospect of the drug-protein binding used in the area of TCM research is also discussed.

Abstract
Human serum albumin (HSA) has its ability to bind drug molecules and influence their efficacies. Although anticancer leads NSC48693 and NSC290956 functioned at the same mechanism, the drug efficacies were obviously distinct. To gain insight into the distinct drug efficacy, the molecular and physiological processes of anticancer leads binding HSA have been investigated via a combined experimental and theoretical approach. The binding site, as characterized by fluorescence quenching and molecular modeling, is found to be located at site II in subdomain III A for NSC48693 with tight binding and at site FA1 in subdomain I B for NSC290956 with negatively cooperative binding, respectively. As indicated by the thermodynamic analysis, NSC48693 binds to HSA with an enthalpy driven mechanism, while NSC290956 binding with HSA is entropically driven. The further kinetic analysis indicates that the association rates appear to be similar to these two anticancer leads, however, the dissociation rate of NSC48693 is approximately 5-fold slower than that of NSC290956. For NSC48693, the pharmacodynamic efficacy is less than that of NSC290956, while its pharmacokinetic behavior is better than that of NSC290956. These parameters influence the pharmacodynamic efficacy and pharmacokinetic behavior, which will give further impacts on drug efficacy in vivo.

Abstract
The interaction between carthamin and human serum albumin (HSA) was investigated by multiple spectroscopic analyses, surface plasmon resonance (SPR), isothermal titration microcalorimetry (ITC), and molecular docking studies. Fluorescence lifetime measurements implied that carthamin quenched the intrinsic fluorescence of HSA with the formation of a new complex via static mode. Binding affinities regarding this interaction were obtained from SPR analysis. Results demonstrated that carthamin could form a 1:1 complex with HSA at the binding affinity of KD=8.726×10-5M and that a high temperature was unfavourable for the interaction. ITC analyses and molecular docking results illustrated that HSA shaped a proper cavity (site I) to embed the whole carthamin molecule and that the complex was formed depending on intermolecular forces, including hydrophobic interaction, hydrogen bonding, and electrostatic force. Moreover, circular dichroism and 3D fluorescence demonstrated that carthamin slightly disturbed the microenvironment of amino residues and affected the secondary structure of HSA.

Abstract
Drug-protein interaction analysis has become a considerable topic in life science which includes clarifying protein functions, explaining drug action mechanisms and uncovering novel drug candidates. This work was to determine the association constants (KA ) of six drugs to β2 -adrenergic receptor by injection amount-dependent method using stationary phase containing the immobilized receptor. The values of KA were calculated to be (25.85 ± 0.035) × 104 m-1 for clorprenaline, (42.51 ± 0.054) × 104 m-1 for clenbuterol, (6.67 ± 0.008) × 104 m-1 for terbutaline, (33.99 ± 0.025) × 104 m-1 for tulobuterol, (7.59 ± 0.011) × 104 m-1 for salbutamol and (78.52 ± 0.087) × 104 m-1 for bambuterol. This rank order agreed well with the data determined by zonal elution, frontal analysis and nonlinear chromatography, even using different batches of β2 -AR column. A good correlation was found between the association constants by the current method and radio-ligand binding assay. Our data indicates that the injection amount-dependent method is a powerful alternative for rapid analysis of ligand-receptor interactions.
