[PMID: 38463294 PMCID: PMC10918653 DOI: 10.1021/acsomega.3c08785] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 12/23/2023] [Accepted: 01/04/2024] [Indexed: 03/12/2024]
Abstract
The current assay aimed to fabricate and analyze a potent wound healing structure based on a naringin (Nar)/β-cyclodextrin (β-CD)-loaded chitosan hydrogel. Using the simulation studies, we assessed the interactions among the Nar, β-CD, and the formation of the inclusion complex. Then, the formation of the hydrogel nanocomplex was simulated and evaluated using the in silico methods. The results showed that after optimization of the structures by DMol3 based on DFT-D, the total energies of Nar, GP, CD, and β-CD were calculated at -2100.159, -912.192, -3778.370, and -4273.078 Ha, respectively. The encapsulation energy of Nar on β-CD in the solvent phase was calculated at -93.626 kcal/mol, and the Nar structure was located inside β-CD in solution. The negative interaction energy value for the encapsulation of Nar on β-CD suggests the exothermic adsorption process and a stable structure between Nar and β-CD. Monte Carlo method was applied to obtain adsorption of CS/GP on Nar/β-CD. Its value of the obtained interaction energy was calculated at -1.423 × 103 kcal/mol. The characterization confirmed the formation of a Nar/β-CD inclusion complex. The Zeta potential of the pristine β-CD changed from -4.60 ± 1.1 to -17.60 ± 2.34 mV after interaction with Nar, and the heightened surface negativity can be attributed to the existence of electron-rich naringin molecules, as well as the orientation of the hydroxyl (OH) group of the β-CD toward the surface in an aqueous solution. The porosity of the fabricated hydrogels was in the range of 70-90% and during 14 days around 47.0 ± 3.1% of the pure hydrogel and around 56.4 ± 5.1 of hydrogel nanocomposite was degraded. The MTT assay showed that the hydrogels were biocompatible, and the wound contraction measurement (in an animal model) showed that the closure of the induced wound in the hydrogel nanocomposite treatment was faster than that of the control group (wound without treatment). The results of this study indicate that the developed bioactive wound healing 3D structure, which is composed of a chitosan hydrogel containing a Nar/β-CD inclusion nanocomplex, has potential as an effective material for wound dressing applications.

Multi-component immune knockout: A strategy for studying the effective components of traditional Chinese medicine. J Chromatogr A 2023; 1692:463853. [PMID: 36780848 DOI: 10.1016/j.chroma.2023.463853] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Revised: 02/03/2023] [Accepted: 02/05/2023] [Indexed: 02/09/2023]
Abstract
Periploca forrestii Schltr., a traditional Chinese medicine (TCM), is commonly used to treat autoimmune diseases such as rheumatoid arthritis (RA). However, its mechanism, involving a variety of cardiac glycosides, remains largely unknown. The immune knockout strategy can highly selectively deplete target components by immunoaffinity chromatography (IAC). We aimed to identify the common structural features of cardiac glycosides in P. forrestii and design IAC to specifically recognize these features to achieve the multi-component knockout of potential active substances from the extracts of P. forrestii. A content detection experiment confirmed that the content of a compound with periplogenin structure (CPS) in the extract of P. forrestii was reduced by 45% by IAC of periplogenin. The immunosuppressive ability of the extract on H9 human T lymphocytic cells was weakened after CPS knockout from P. forrestii extract. Molecular biology experiments showed that mRNA expression of interferon-γ (IFN-γ), interleukin-2 (IL-2), and interleukin-6 (IL-6) in H9 cells was up-regulated after CPS knockout, while no significant changes in the expression of interleukin-4 (IL-4) were found. CPS knockout from P. forrestii extract did not cause significant changes in the proliferation of lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells incubated with this extract. These results indicate that CPS exhibited immunosuppressive effects via inhibiting the T helper 1 (Th1) cell immune response and not via the anti-inflammatory components in P. forrestii. This is the first use of IAC to achieve multi-component knockout in TCM extracts for identifying effective compounds. This method is effective and reliable and warrants further exploration.

Development of a highly sensitive and specific monoclonal antibody-based ELISA coupled with immuno-affinity extraction for the detection of anticancer drug 5-fluorouracil in blood samples. Talanta 2022; 249:123655. [PMID: 35696979 DOI: 10.1016/j.talanta.2022.123655] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2022] [Revised: 05/29/2022] [Accepted: 06/03/2022] [Indexed: 10/31/2022]
Abstract
5-Fluorouracil (5-FU) is an effective anticancer drug widely used in cancer treatment. In this study, two 5-FU derivatives containing a spacer arm with the carboxylic group at the end were synthesized, which were linked to the carrier proteins to form 5-FU-protein conjugates used as the immunogens for the production of monoclonal antibody (mAb). Based on the produced mAb, the highly sensitive and specific enzyme-linked immunosorbent assay (ELISA) for 5-FU detection was established. The IC50 and LOD values of the assay were found to be 19.5 ng mL-1 and 0.5 ng mL-1, respectively. There was no cross-reactivity (CR) of the ELISA with cytosine, thymine and uracil, which avoided the interference from inherent pyrimidines. The CR values of the assay with three substitutes of 5-FU (tegafur, 5-fluoro-2'-deoxyuridine, carmofur) were within 9.7%-17.6%. The produced mAb was also applied in sample extraction. The immuno-affinity column capable specific capturing 5-FU was prepared by immobilizing the mAb on Sepharose-4B gel and filling into a SPE column. The recoveries of 5-FU in spiked samples measured by ELISA were 72.4%-90.7% with RSD of 3.6%-8.3%. Five blood samples collected from patients were extracted by immuno-affinity column, then measured by ELISA and confirmed by HPLC-MS/MS. There was a good correlation between HPLC-MS/MS and ELISA. It is demonstrated that the developed ELISA combined with immuno-affinity extraction can be a powerful alternative method for the detection of 5-FU in blood samples.

Abstract
Naringin is a flavonoid found primarily in citrus species with especially high concentrations being present in grapefruit (Citrus paradisi), bitter orange (Citrus aurantium), and pomelo (Citrus grandis). Because of its many positive effects on human health, naringin has been the focus of increasing attention in recent years. Recently, conventional extraction methods have been commonly replaced with unconventional methods, such as ultrasound-assisted extraction (UAE) and other, more eco-friendly extraction methods requiring little-to-no environmentally harmful solvents or significantly less energy. Naringin analysis is most commonly done via high-performance liquid chromatography (HPLC), and ultrahigh-performance liquid chromatography (UHPLC) coupled with a mass spectrometer (MS) or a photodiode array (DAD) detector. The aim of this review is to provide an overview of recent trends developments in the extraction, sample preparation, and liquid chromatographic analysis of the compound originating from citrus fruits or their products.

Abstract
In this study, we present a review on a useful approach, namely, immunoaffinity column coupled with monoclonal antibodies (MAbs), to separate natural compounds and its application for cell-based studies. The immunoaffinity column aids in separating the specific target compound from the crude extract. The column capacity was stable even after more than 10 purification cycles of use under the same conditions. After applying the crude extract to the column, the column was washed with washing buffer and eluted with elution buffer. The elution fraction contained the target compound bound to MAb, whereas the washing fraction was the crude extract, which contained all compounds except a group of target compounds; therefore, the washing fraction was referred to as a knockout (KO) crude extract. Cell-based studies using the KO extract revealed the actual effects of the natural compounds in the crude extract. One-step separation of natural compounds using the immunoaffinity column coupled with MAbs may help in determining the potential functions of natural compounds in crude extracts.

Abstract
An immunoblotting system ("eastern blotting") was developed for small-molecule herbal medicines like glycosides, with no conjugation function to the membrane. Briefly, the crude extracts of herb medicines were developed by thin-layer chromatography (TLC). The small-molecule herbal medicines on TLC plates were transferred to polyvinylidene fluoride (PVDF) or polyethersulfone (PES) membranes by heating. Antigen components were divided into two categories based on their function, i.e., their membrane recognizing (aglycone part) and fixing (sugar moiety) abilities. This procedure allows for the staining of only target glycosides. Double eastern blotting was developed as a further staining system for two herb medicines using a set of MAbs and substrates.

Abstract
This review is the ninth update of the original article published in 1999 on the application of matrix-assisted laser desorption/ionization (MALDI) mass spectrometry to the analysis of carbohydrates and glycoconjugates and brings coverage of the literature to the end of 2016. Also included are papers that describe methods appropriate to analysis by MALDI, such as sample preparation techniques, even though the ionization method is not MALDI. Topics covered in the first part of the review include general aspects such as theory of the MALDI process, matrices, derivatization, MALDI imaging, fragmentation and arrays. The second part of the review is devoted to applications to various structural types such as oligo- and poly-saccharides, glycoproteins, glycolipids, glycosides and biopharmaceuticals. Much of this material is presented in tabular form. The third part of the review covers medical and industrial applications of the technique, studies of enzyme reactions and applications to chemical synthesis. The reported work shows increasing use of combined new techniques such as ion mobility and the enormous impact that MALDI imaging is having. MALDI, although invented over 30 years ago is still an ideal technique for carbohydrate analysis and advancements in the technique and range of applications show no sign of deminishing. © 2020 Wiley Periodicals, Inc.

Abstract
Shaoyao-Gancao decoction, a Chinese herbal formula, is composed of Paeoniae Radix alba and Glycyrrhiza Radix et rhizoma. It has been widely used to treat muscle spasms and asthma. However, little is known about the bioactive components of Shaoyao-Gancao decoction. In the present study, the bioactive compounds in water-extract of Shaoyao-Gancao decoction were separated by the immobilized β2 -adrenoceptor affinity column and identified using quadrupole time-of-flight mass spectrometry. The affinity constants of the separated compounds that bind to β2 -adrenoceptor were determined by frontal analysis. Compound bioactivity was tested in a rat tracheal smooth muscle relaxation assay. We identified the bioactive compounds in the water extract of Shaoyao-Gancao decoction that bound to the β2 -adrenoceptor as paeoniflorin and liquiritin. Paeoniflorin and liquiritin had only one binding site on the immobilized β2 -adrenoceptor, and the affinity constants were (2.16 ± 0.10) × 104 M-1 and (2.95 ± 0.15) × 104 M-1 , respectively. Both compounds induced a concentration-dependent relaxation of tracheal smooth muscle following K+ -stimulated contraction, and the relaxation effects were abrogated by the β2 -adrenoceptor antagonist, ICI 118551. Therefore, paeoniflorin and liquiritin are bioactive compounds in Shaoyao-Gancao decoction and the β2 -adrenoceptor affinity chromatography is a useful tool for identifying potential β2 -adrenoceptor ligands in natural products used in traditional Chinese medicine.

Abstract
Owing to the widespread application value, monoclonal antibodies (MAbs) have become a tool of increasing importance in modern bioscience research since their emergence. Recently, some researchers have focused on the production of MAbs against medical plant-derived natural products (MPNP), the secondary metabolites of medical plants. At the same time, various immunoassay methods were established on the basis of these MPNP MAbs, and then rapidly developed into a novel technique for medical plant and phytomedicine research in the area of quality control, pharmacological analysis, drug discovery, and so on. Dependent on the research works carried out in recent years, this paper aims to provide a comprehensive review of MAbs against MPNP and the application of various immunoassay methods established on the basis of these MAbs, and conclude with a short section on future prospects and research trends in this area.
