[PMID: 38944077 DOI: 10.1016/j.ijbiomac.2024.133450] [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: 12/21/2023] [Revised: 06/13/2024] [Accepted: 06/24/2024] [Indexed: 07/01/2024]
Abstract
Xanthine oxidase (XO) is a typical target for hyperuricemia and gout, for which there are only three commercial xanthine oxidase inhibitors (XOIs): febuxostat, topiroxostat and allopurinol. However, these inhibitors have problems such as low bioactivity and several side effects. Therefore, the development of novel XOIs with high bioactivity for the treatment of hyperuricemia and gout is urgently needed. In this work we constructed a XO immobilized cellulose membrane colorimetric biosensor (XNCM) by the TEMPO oxidation, amide bond coupling and nitro blue tetrazolium chloride (NBT) loading method. As expected, the XNCM was able to detect xanthine, with high selectivity and sensitivity by colorimetric method with a distinctive color change from yellow to purple, which can be easily observed by the naked-eye in just 8 min without any complex instrumentation. In addition, the XNCM sensor performed screening of 21 different compounds and have been successfully pre-screened out XOIs with biological activity. Most importantly, the XNCM was able to quantitatively detect the IC50 values of two commercial inhibitors (febuxostat and allopurinol). All the results confirmed that the XNCM is a simple and effective tool which can be used for the accelerated screening of XOIs and has the potential to uncover additional XOIs.

Benzyl-isoquinoline alkaloids rich extract of Coptis teeta Wall., exhibit potential efficacy in calcium-oxalate and uric-acid linked metabolic disorders. Fitoterapia 2024; 177:106050. [PMID: 38838823 DOI: 10.1016/j.fitote.2024.106050] [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: 01/31/2024] [Revised: 05/31/2024] [Accepted: 06/01/2024] [Indexed: 06/07/2024]
Abstract
Coptis teeta Wall., an endangered but valuable medicinal species having various folklore uses in Indian and Chinese Traditional system of medicine. Its distribution is restricted to India, China and Tibet. In India, C. teeta is traditionally used in joint disorders, urinary infections and inflammatory diseases, however the scientific validation is missing. Thus, the present study aims to validate the anti-lithiatic and anti-gout activity of C. teeta rhizome extract (CTME) through in-vitro biological assays. The metabolic fingerprinting of CTME through reverse phase-high performance liquid chromatography-photodiode array (RP-HPLC-PDA) showed the presence of five benzyl-isoquinoline alkaloids, namely berberine (2.59%), coptisine (0.746%) jatrorrhizine (0.133%), palmatine (0.03%) and tetrahydropalmatine (0.003%). The anti-gout potency analysed via in-vitro xanthine oxidase (XOD) inhibition assay, followed by HPTLC (High performance thin layer chromatography) mediated bio-autographic inhibition of XOD signifies that CTME exhibit strong inhibition of XOD (IC50: 3.014 μg/ml), insignificantly different (p > 0.05) from allopurinol (IC50: 2.47 μg/ml). The XOD bioautographic assay advocates that the efficacy is primarily due to berberine and coptisine alkaloids. The CTME has significant anti-lithiatic activity, and thereby limiting the progression of crystal nidus formation, mediated via inhibition of calcium oxalate crystals nucleation and aggregation. Additionally, the extract also exhibits potential effect on inhibition of oxidative stress associated inflammation, which plays crucial role in alleviating urolithiasis and gouty conditions. Validating the traditional claims of C. teeta will not only confirm its medicinal benefits for targeted pathological conditions but also enhance its industrial demand.

A feasible HPTLC method for concurrent quantitation of allopurinol-montelukast co-therapy in plasma and evaluation of their hepatic and renal effects in rats: Analytical, biochemical, and histopathological study. J Pharm Biomed Anal 2023; 233:115439. [PMID: 37186992 DOI: 10.1016/j.jpba.2023.115439] [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: 02/17/2023] [Revised: 04/30/2023] [Accepted: 05/01/2023] [Indexed: 05/17/2023]
Abstract
Recent studies presented the crucial role of montelukast (MON, a leukotriene receptor antagonist) against gouty arthritis and its protective effect on drug-induced liver and kidney injury. Allopurinol (ALO, a selective xanthine oxidase inhibitor) is also used for treatment of hyperuricemia, however, it induces hepatotoxicity and acute kidney injury. Therefore, this study introduces the first analytical/biochemical/histopathological assay for MON-ALO co-therapy and aims to: inspect the hepatic and renal impacts of ALO, MON and their combination in rats via biochemical and histopathological examinations, propose and validate a facile HPTLC method for concurrent estimation of ALO-MON binary mixture in human plasma, and employ this method to attain the targeted drugs in real rat plasma. First, the cited drugs in human plasma were simultaneously separated utilizing silica gel G 60 F254-TLC plates. The separated bands were scanned at 268 nm demonstrating appropriate linearities (50.0-2000.0 ng band-1 for each drug) and correlations (0.9986 and 0.9992 for ALO and MON, correspondingly). The calculated detection and quantitation limits, as well as recoveries confirmed the method's reliability. This procedure was validated, and the stability studies were achieved according to Bioanalytical Method Validation Guideline. This work was extended to investigate the possible hepatic and renal effects of ALO, MON and their co-therapy in rats. Using rat's gastric tube, the following was administered to four groups of male Wistar rats: Group Ia and Ib as control (received either saline or DMSO), Groups II, III, and IV were given MON, ALO, and MON+ALO, respectively. Good correlation between the measured biochemical parameters and the observed histopathological changes was encountered. Considerable drop in aspartate transaminase and alanine transaminase levels, in addition to lower liver damage changes were observed in the combination group compared to MON or ALO-treated groups. Regarding renal changes, ALO-MON co-therapy caused elevation in the serum creatinine and blood urea nitrogen levels when compared to controls and MON- or ALO-treated groups. Severe proteinaceous casts accumulation in kidney tubular lumen, severe congestion, and severe tubular necrosis were also noticed in the combination group. Lastly, this study suggests ALO-MON co-treatment not only as a preventive therapy against gouty arthritis but also as a new line to minimize ALO-induced hepatic injury. However, co-administration of ALO and MON should be further studied to assess the benefits and risks in various tissues, adjust the MON dosing, and monitor its nephrotoxic effect.

Abstract
Thin-layer chromatography (TLC) is widely used for food analysis and quality control. As an open chromatographic system, TLC is compatible with microbial-, biochemical-, and chemical-based derivatization methods. This compatibility makes it possible to run in situ bioassays directly on the plate to obtain activity-profile chromatograms, i.e., the effect-directed analysis of the sample. Many of the properties that can be currently measured using this assay format are related to either desired or undesired features for food related products. The TLC assays can detect compounds related to the stability of foods (antioxidant, antimicrobial, antibrowning, etc.), contaminants (antibiotics, pesticides, estrogenic compounds, etc.), and compounds that affect the absorption, metabolism or excretion of nutrients and metabolites or could improve the consumers health (enzyme inhibitors). In this article, different food related TLC-assays are reviewed. The different detection systems used, the way in which they are applied as well as selected examples are discussed.

Development of a validated HPTLC-bioautographic method for evaluation of aromatase inhibitory activity of plant extracts and their constituents. PHYTOCHEMICAL ANALYSIS : PCA 2022; 33:115-126. [PMID: 34171936 DOI: 10.1002/pca.3074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 05/08/2021] [Accepted: 06/03/2021] [Indexed: 06/13/2023]
Abstract
INTRODUCTION Aromatase is a CYP450 enzyme that catalyses the conversion of androgens into oestrogens, where the decrease in the production of oestrogens aided by aromatase inhibitors is considered a target in post-menopausal breast cancer therapy. TLC-bioautography is a technique employed for combining chromatographic separations on TLC plates with bioassays. This is the first report to evaluate aromatase inhibitory activity using this technique. OBJECTIVES The aim of this study is to develop and validate a new TLC-bioautographic method for determination of aromatase inhibitory activity in 14 plant extracts. Two quantitation methods, the peak area method and reciprocal iso-inhibition volume (RIV) method, were compared and investigated to attain reliable results. Factors affecting the enzymatic reaction (temperature, pH, enzyme and substrate concentrations … etc.) were also investigated to attain the optimum parameters. METHODOLOGY TLC assisted by digital image processing was implemented for quantitative estimation of the aromatase inhibition of 14 plant extracts using chrysin as positive control. The fluorometric substrate dibenzyl fluorescein (DBF) was utilised for the assay, where inhibitory compounds were visualised as dark spots against a blue fluorescent background. Two software programs, Sorbfil® videodensitometer (in the peak area method) and ImageJ® (in the RIV method), were thoroughly validated using the International Council on Harmonisation (ICH) guideline and used for quantitation. RESULTS The RIV method showed superiority over the peak area method in the quantitation results of the tracks with non-homogenous background with %RSD values of 0.98 and 1.49 compared with 2.86 and 3.58, respectively. Further, the methods allow the comparison of the activity of different unknown inhibitory compounds without the need for a reference or a positive control. CONCLUSION Using the TLC-bioautographic method by image processing combined with the RIV quantitation method, simultaneous separation and quantitation of aromatase inhibitory components could be applied to estimate the relative activity of various plant extracts.

Abstract
In this study, total saponins were extracted from Pleurotus ostreatus cultivated with Astragalus as one of organic culture substrates. High Performance Thin Layer Chromatography (HPTLC) assay showed total saponins could be separated effectively, and four kinds of spots were identified as AG I, AG II, AG III, and AG IV, respectively. FTIR spectra based on HPTLC separation assay showed the saponin characteristic groups including -OH, C-H, C=O, and the glycoside linkaged to sapogenin group C-O-C, suggesting the four kinds of spots belonged to cycloartane-type triterpene saponins. The primary mass spectra of precursor ion (HPTLC-ESI-MS) assay further proved the main composition of four kinds of spots was AG I-IV, respectively. Physical properties, including the detection of specific rotation and melting point, revealed the separation of high-purity saponin monomer by HPTLC. HPTLC-dual wavelength spectrodensitometric method detection showed that content of astragaloside I-IV was ranged from 0.2 to 0.5 mg/g, and the total astragalosides contents attained to 1.397 mg/g, indicating P. ostreatus could bioaccumulate astragalosides from Astragalus. These results demonstrated the characterization of astragalosides based on the separation of HPTLC was effective, and supported to consider astragalosides-enriched P. ostreatus as functional edible fungus for food and medical applications. PRACTICAL APPLICATION: Currently, the consumption of enriched foods has become common and continues to increase due to urgent demanding for foods with high nutritional value. Pleurotus ostreatus is a functional edible fungus, which not only can produce secondary metabolites, but can enrich bioactive ingredients. Astragalosides have a wide range of biological activities, especially currently being tested as cardioprotective agent. In this study, P. ostreatus was cultivated through adding Astragalus into culture substrates, which realized massive enrichment of astragalosides. Astragalosides-enriched P. ostreatus as functional edible fungus could be extensively used in food and medical areas, especially for the prevention of cardiovascular diseases.

Abstract
Microorganisms and plants can be important sources of many compounds with potential pharmaceutical applications. Extraction of these matrices is one of the ways of identifying the presence of inhibitory active substances against enzymes whose high activity leads to serious human diseases including cancer, Parkinson's or Crohn's diseases. The isolation and purification of inhibitors are time-consuming and expensive steps in the analysis of the crude extract and therefore, it is necessary to find a fast, efficient, and inexpensive method for screening extracts of interest. TLC-Bioautography combines the separation of the extract on a thin layer with its subsequent biological analysis. TLC-Bioautography methods have been developed for several classes of enzymes including oxidoreductases, hydrolases and isomerases, and there is a potential for developing functional methods for other classes of enzymes. This review summarizes known TLC-Bioautography methods and their applications for determining the presence of enzyme inhibitors in extracts and compares the effectiveness of different methodological approaches. It also indicates the current state and perspective of the development of TLC-Bioautography and its possible future applications.

Abstract
Background:
TLC bioautography is a hyphenated technique combining planar chromatographic
separation and in situ biological activity detection. This coupled method has been receiving
much attention in screening bio-active natural products because of its properties of being simple, rapid,
inexpensive, and effective.
Methods:
The recent progress in the development of method of TLC bioautography for detecting antimicrobial
and enzyme inhibitory activities dating between 2012 and early 2018 has been reviewed.
The applications of this method in biological screening of natural products were also presented.
Results:
Some anaerobic and microaerophilic bacteria and a causative bacterium of tuberculosis have
been adopted to TLC direct bioautography. Seven types of enzymes including acetylcholinesterase,
glucosidase, lipase, xanthine oxidase, tyrosinase, monoamine oxidase, and dipeptidyl peptidase IV
have so far been adopted on TLC bioautography. Its new application in screening antiurolithiatic
agents was included.
Conclusion:
The standard experimental procedures are required for TLC antioxidant and antimicrobial
assays. Some new enzymes should be attempted and adopted on TLC bioautography. The existing
TLC methods for enzyme inhibition need more application studies to assess their screening capacity
in the discovery of active compounds. The GC-MS or LC-MS approaches have gradually been
coupled to TLC bioautography for fast structural characterization of active compounds.
