Identification of high-concern organic pollutants in tap waters from the Yangtze River in China based on combined screening strategies. THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 857:159416. [PMID: 36244484 DOI: 10.1016/j.scitotenv.2022.159416] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Revised: 10/09/2022] [Accepted: 10/09/2022] [Indexed: 06/16/2023]
Abstract
Recently, numerous organic pollutants have been detected in water environment. The safety of our drinking water has attracted widespread attention. Effective methods to screen and identify high-concern substances are urgently needed. In this study, the combined workflow for the detection and identification of high-concern organic chemicals was established and applied to tap water samples from the Yangtze River Basin. The solid phase extraction (SPE) sorbents were compared and evaluated and finally the HLB cartridge was selected as the best one for most of the contaminants. Based on target, suspect and non-target analysis, 3023 chemicals/peaks were detected. Thirteen substances such as diundecyl phthalate (DUP), 2-hydroxyatrazine, dioxoaminopyrine and diethyl-2-phenylacetamide were detected in drinking water in the Yangtze River Basin for the very first time. Based on three kinds of prioritization principles, 49 ubiquitous, 103 characteristic chemicals and 13 inefficiently removed chemicals were selected as high-concern substances. Among them, 8, 31, 9, 3, 4 substances overlapped with the toxic, risky or high-concern chemicals lists in China, America, European Union, Japan, Korea, respectively. Specific management and removal strategies were further recommended. The workflow is efficient for identification of key pollutants.

Encapsulation of indole-3-carbinol in Pickering emulsions stabilized by OSA-modified high amylose corn starch: Preparation, characterization and storage stability properties. Food Chem 2022; 386:132846. [PMID: 35381538 DOI: 10.1016/j.foodchem.2022.132846] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 10/27/2021] [Accepted: 03/27/2022] [Indexed: 11/24/2022]
Abstract
The stability of hydrophobic bioactive compound indole-3-carbinol (I3C) is a challenge for application. In this work, Pickering emulsions were prepared to encapsulate I3C. As the emulsifier, high amylose corn starch was pretreated by acid hydrolysis, afterwards modified by different concentrations of octenyl succinic anhydride (OSA), and their emulsions were evaluated. The XRD, SEM and FTIR results indicated the successful modification. ζ-potential, mean droplet size and emulsification index (EI) of the emulsions confirmed that modified starch with a higher degree of substitution (DS) was more effective for enhancing the storage stability. The results of encapsulation efficiency (EE) and retention degree of I3C after 14 d also proved the assumption. Moreover, the Pickering emulsions protected I3C against ultraviolet light and achieved controlled release in vitro. The food-grade Pickering emulsion loading I3C is promising to be used as a nutrient or dietary supplement for food applications.

Pharmacokinetic and Pharmacodynamic Properties of Indole-3-carbinol in Experimental Focal Ischemic Injury. Eur J Drug Metab Pharmacokinet 2022; 47:593-605. [PMID: 35482227 DOI: 10.1007/s13318-022-00771-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/03/2022] [Indexed: 11/03/2022]
Abstract
BACKGROUND AND OBJECTIVES Indole-3-carbinol (I3C) is reported to have neuroprotective properties in an animal model of ischemic stroke. However, the pharmacokinetics of I3C in stroke animals are unknown. Furthermore, the most effective method of I3C delivery for the treatment of stroke has yet to be determined. Therefore, the objective of this study was to evaluate pharmacokinetics and pharmacodynamics of I3C to discover the most effective delivery route for protecting the brain from ischemic injury. METHODS With oral and intravenous administration, the pharmacokinetics and pharmacodynamics of I3C in sham and middle cerebral artery occluded (MCAO) rats were investigated. RESULTS I3C administration in sham and MCAO rats did not alter the pharmacokinetic parameters such as maximum plasma concentration (Cmax), time to reach Cmax, half-life, area under the curve, mean residential time, volume of distribution, clearance, bioavailability, and tissue distribution. A higher amount of diindolylmethane (DIM) was observed with oral administration of I3C compared to intravenous administration in the plasma (5 fold), brain (4 fold), and cerebrospinal fluid (CSF) (2-3 fold). Orally delivered I3C significantly reduced neurological deficits, brain infarction (20%), blood-brain barrier leakage (15 μg/g), and brain water content (75%) in MCAO rats compared to intravenous administration of I3C. CONCLUSIONS I3C pharmacokinetic parameters were similar in sham and MCAO rats, but I3C and DIM penetration in the brain and CSF was significantly higher in MCAO rats than in sham animals, and I3C oral intake significantly reduced MCAO-induced neurological impairments. Consequently, compared to intravenous treatment, I3C oral delivery is more effective in treating ischemic stroke.

A facile and sensitive HPLC-MS/MS method for quantification of 3,3'-diindolylmethane in plasma samples. Biomed Chromatogr 2021; 36:e5296. [PMID: 34875720 DOI: 10.1002/bmc.5296] [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: 06/08/2021] [Revised: 11/17/2021] [Accepted: 11/18/2021] [Indexed: 11/12/2022]
Abstract
Indole-3-carbinol is the subject of ongoing biomedical research owing to its potential antiatherogenic, anticarcinogenic and antioxidant effects. The antitumor properties are mainly associated with its major metabolite, i.e. 3,3'-diindolylmethane (DIM). Typically, the biological activity of the chemical compound is manifested in the ng/ml concentration range. Consequently, the development of highly sensitive analytical methods to determine DIM in various biological samples is an urgent issue. In this study, an HPLC-MS/MS method was established for the quantification of DIM in human plasma. The developed method was validated according to the European Medicines Agency guidelines. Sensitivity, selectivity, accuracy and precision were good, allowing DIM quantification in the concentration range of 5-500 ng/ml. The limit of detection and the lower limit of quantification were 1 and 5 ng/ml, respectively. 4-Methoxy-1-methylindole was used as an internal standard (IS). The analytes were extracted from the human plasma by the acetonitrile-induced protein precipitation method with the addition of 3 mol/L ammonium sulfate as a salting-out agent, which is a facile and efficient approach for high-throughput bioanalysis. The chromatographic separation was performed on the Synergi Fusion-RP C18 column (50 × 2.0 mm, 4 μm, 80 Å) under isocratic elution at 40°C. The mobile phase consisting of acetonitrile and water (0.1% formic acid; 85:15, v/v) was delivered at a flow rate of 0.20 ml/min. DIM and the IS were eluted at 2.36 ± 0.04 and 2.43 ± 0.03 min, respectively. The total analysis time was 3.20 min. Atmospheric pressure chemical ionization was carried out using multiple reaction monitoring in the positive polarity mode. The ion transitions were set to m/z 247.1 → 130.1 (DIM) and 162.1 → 147.1 (IS). The method was successfully applied to the analysis of plasma samples after a single oral administration of the Indinol® Forto drug (200 mg) to healthy female Russian volunteers. Also, the developed method was used for the analysis of rabbit plasma samples after a single oral dose of DIM (20 mg/kg).

Abstract
Numerous epidemiological studies have indicated the potential effects of glucosinolates and their metabolites against cancer as well as other non-communicable diseases, such as cardiovascular disease and neurodegenerative disorders. However, information on the presence and quantity of glucosinolates in commonly consumed vegetables and in human fluids is sparse, largely because well-standardised methods for glucosinolate determination are not available, resulting in published data being inconsistent and conflicting. Thus, studies published since 2002 on the most recent developments of glucosinolate extraction and identification have been collected and reviewed with emphasis on determination of the intact glucosinolates by LC-MS and LC-MS/MS. This overview highlights the glucosinolate extraction methods used, the stability of glucosinolates during extraction, the availability of stable isotope labelled internal standards and the use of NMR for purity analysis, as well as the current analytical techniques that have been applied for glucosinolate analysis, e.g. liquid chromatography with mass spectrometric detection (LC-MS). It aims to interpret the findings with a focus on the development of a validated method, which will help to determine the glucosinolate content of vegetative plants and human tissues, and the identification and determination of selected glucosinolate metabolites.
