Hamad AA, Derayea SM. A novel and unusual utility of the cardiosintol drug as a fluoro-prober in the amendment of a highly fluorescent module for determining the non-fluorescent N-acetylcysteine drug. SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2023; 293:122460. [PMID: 36780744 DOI: 10.1016/j.saa.2023.122460] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Revised: 01/31/2023] [Accepted: 02/04/2023] [Indexed: 06/18/2023]
Abstract
It is common to use reagents to determine the drugs by exploiting the properties of these reagents in the development of fluorescence of the target drug or sometimes increasing its intensity; this is the usual and predominant in the methods used in various techniques. But using a drug as a reagent to analyze another drug is unique, unusual, and uncommon; that's the idea of this paper. This is possible by creating a chemical modulation in the drug's structure using another drug. Targeted analyte molecules (N-acetylcysteine, as an example) that lack fluorogenic or chromophoric moieties cannot be monitored or evaluated without undergoing structural modification. Thus, the chemical mending of the analyte's molecular structure can achieve the transformational process. This protocoled analytical method generates an amended fluorescence sensation that can be chased fluorimetrically at 441 nm (emission) following excitation at 339 nm. When o-dialdehyde, diformylbenzene, a non-fluorescent moiety, is added to a solution of non-fluorescent analyte in the presence of cardiosintol drug, at a specific pH, the target drug-thiol moiety can be amended into a highly fluorescent compound. This study presented a sensitive and feasible fluorometric test for acetylcysteine. The response is linear throughout the range of 0.05-0.80 µg mL-1. Quantum yield and procedure validation were evaluated according to I.C.H. standards. The formed mutated product was successfully applied to the precise assessment of the studied drug in batch powder and dose form(s), with no impact from excipients. Compared to the referenced publication, the outcomes demonstrate remarkable precision and accuracy.

Abstract
In the present study, a novel spectrofluorimetric approach was designed for the analysis of captopril as a thiol-containing compound. The approach is based on the formation of a ternary fluorescent compound between the target thiol compound, ortho-phthaldehyde, and a suitable primary amine-containing compound. The produced 1-thio-alkyl-isoindole derivative exhibited very high emission activity in a faintly alkaline aqueous solution that could be monitored at 448 nm (excitation at 334 nm). 2-Amino-6-methyl-6-hydroxy-heptane was selected as the primary amine candidate that gave the high fluorescence intensity with the stability of the formed product. At the optimal experimental condition, the intensity of fluorescence of the formed product was linearly related to the concentration of captopril in 20-450 ng mL-1 range. Commercial pharmaceutical tablets were analyzed, and the obtained results agreed with those of the published method regarding precision and accuracy. The mechanism of the reaction was discussed. In addition, the greenness of the approach was rated following eco-scale criteria.

Abstract
Carbon dots (CDs) was facilely synthesized from aspartic acid through a pyrolysis method in this work. Based on their favorable fluorescence property, CDs was utilized to design a metal ions-mediated fluorescent probe for N-acetyl-L-cysteine (NAC) detection. The fluorescence intensity of CDs was firstly quenched by manganese ion (Mn2+ ) through static quenching effect and subsequently restored by NAC via the combination with Mn2+ owing to the coordination effect. Therefore, the fluorescent turn-on sensing of NAC was actuated based on the fluorescence quenching stimulated by Mn2+ and recovery induced by coordination. The fluorescence recovery efficiencies showed a proportional range to the concentration of NAC in the range of 0.04-5 mmol L-1 and the detection limit was 0.03 mmol L-1 . Further, this metal ions-mediated fluorescent nanoprobe was applied to human urine sample detection and the standard recovery rates were located in the range of 97.62-102.34 %. It was the first time that Mn2+ was used to construct fluorescent nanoprobe for NAC. Compared to other heavy metal ions, Mn2+ with good biosecurity prevented the risk of application, which made the nanoprobe green and bio-practical. The facile synthesis of CDs and novel metal ions-mediated sensing mode made it a promising method for pharmaceutical analysis.

Abstract
Chinese Korean ethnic rice wine, a traditional fermented wine made from rice or corn, has antioxidant and antihypertensive activities. Although the determination of amino acids and other nutrients in rice wine has been reported, the existence of chiral thiol compounds has not been published in the literature. Therefore, we established a highly sensitive and selective ultrahigh-performance liquid chromatography-high-resolution mass spectrometry method for simultaneous determination and chiral separation of dl-Cys-GSH, dl-Cys-Cys, and dl-Cys-Hcy based on (R)-(5-(3-isothiocyanatopyrrolidin-1-yl)-5-oxopentyl) triphenylphosphonium derivatization. Three thiol diastereomers were completely separated on a YMC Triart C18 (2.0 × 150 mm, 1.9 μm) column with a resolution value (Rs) ≥ 1.52. The correlation coefficients were ≥0.9996, limit of detection was 2.40-7.20 fmol, and mean recoveries were 83.33-98.59%. Furthermore, fitted curves for dynamic changes in three kinds of chiral thiols in 10 human urine samples after drinking rice wine were drawn. Meanwhile, the metabolic changes in d/l-thiol compounds in human urine were investigated.

Abstract
Background:
Significant advances have been occurred in analytical research since the 1970s
by Liquid Chromatography (LC) as the separation method. Reverse Phase Liquid Chromatography
(RPLC) method, using hydrophobic stationary phases and polar mobile phases, is the most commonly
used chromatographic method. However, it is difficult to analyze some polar compounds with this
method. Another separation method is the Normal Phase Liquid Chromatography (NPLC), which involves
polar stationary phases with organic eluents. NPLC presents low-efficiency separations and
asymmetric chromatographic peak shapes when analyzing polar compounds. Hydrophilic Interaction
Liquid Chromatography (HILIC) is an interesting and promising alternative method for the analysis of
polar compounds. HILIC is defined as a separation method that combines stationary phases used in the
NPLC method and mobile phases used in the RPLC method. HILIC can be successfully applied to all
types of liquid chromatographic separations such as pharmaceutical compounds, small molecules, metabolites,
drugs of abuse, carbohydrates, toxins, oligosaccharides, peptides, amino acids and proteins.
Objective:
This paper provides a general overview of the recent application of HILIC in the pharmaceutical
research in the different sample matrices such as pharmaceutical dosage form, plasma, serum,
environmental samples, animal origin samples, plant origin samples, etc. Also, this review focuses on
the most recent and selected papers in the drug research from 2009 to the submission date in 2020,
dealing with the analysis of different components using HILIC.
Results and Conclusion:
The literature survey showed that HILIC applications are increasing every
year in pharmaceutical research. It was found that HILIC allows simultaneous analysis of many compounds
using different detectors.

Abstract
(1) Antioxidants are involved in body protection mechanisms against reactive oxygen species. Amino acids such as glutathione (GSH) and N-acetylcysteine (NAC) are known to be involved in providing protection against oxidative lethality. A quick and simple method for the determination of NAC and GSH in various biological matrices such as urine, plasma, and homogenates of brain tissues has been developed and described in this work. (2) The assay is based on reversed phase high performance liquid chromatography with spectrofluorimetric detection and on-column derivatization. Butylamine and o-phthaldialdehyde have been used as derivatization reagents. Since o-phthaldialdehyde constitutes a part of the mobile phase, the derivatization reaction and chromatographic separation occur simultaneously. (3) Linearity in the detector response for NAC in human urine was observed in the range of 5–200 nmol mL−1, and NAC and GSH in the brain tissue homogenates were observed in the range of 0.5–5 nmol mL−1 and 0.5–15 nmol mL−1, respectively. Human plasma linearity ranges covered 0.25–5.00 nmol mL−1 and 0.5–15 nmol mL−1 for NAC and GSH, respectively. The LODs for NAC and GSH were 0.01 and 0.02 nmol mL−1 while the LOQs were 0.02 and 0.05 nmol mL−1, respectively. The usefulness of the proposed method was proven through its application to real samples.

Abstract
A sensitive and rapid high-performance liquid chromatography (HPLC) method was developed to enantioseparation of N-acetyl-dl-cysteine after precolumn derivatization using o-phthaldialdehyde and primary aliphatic amines. Seven polysaccharide-based chiral columns were tested in a reversed phase mode. Under the optimal chromatographic conditions, N-acetyl-dl-cysteine derivatives were completely enantioseparated on Chiralcel OZ-3R column with the resolution more than 2.5. The impact of various primary aliphatic amine additives as co-reagents (ethyl-, 1-propyl-, 1-butyl-, 1-pentylamine, (R)-sec-butylamine, tert-butylamine, isobutylamine, cyclopropyl-, cyclobutyl-, cyclopentyl and cyclohexylamine) used in precolumn derivatization step on the retention behavior (retention factor, selectivity and column efficiency) of N-acetyl-dl-cysteine derivatives was investigated. The effect of chromatographic conditions including acetonitrile content in the mobile phase, mobile phase pH, salt concentration in the mobile phase and column temperature on the retention and selectivity was investigated. The developed method was properly validated in terms of linearity, sensitivity (limit of detection and limit of quantification), accuracy, precision, intermediate precision and selectivity according to International Council for Harmonisation (ICH) of Technical Requirements for Pharmaceuticals for Human Use guidelines using internal normalization procedure. Proposed HPLC method was successfully applied to the determination of optical purity in commercially available N-acetyl-L-cysteine samples.
