Abstract
Aging is a natural process that occurs in all living organisms. Particularly, the skin embodies aging since it serves as a barrier between the body and its surroundings. Previously, we reported the wound healing effect of Launaea procumbens and identified compounds therein. The study aims to explore the skin anti-aging properties of the plant extract. To that effect, the antioxidant potential of L. procumbens methanolic extract (LPM) was assessed using two complementary DPPH and FRAP assays. The enzyme inhibitory effect of the extract on collagenase, elastase, hyaluronidase, and tyrosinase was evaluated to assess the direct skin anti-aging effects. Similarly, the anti-inflammatory activity was evaluated to explore the indirect anti-aging effects via the assessment of extract inhibitory effects on cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX). In addition, ADMET and molecular docking studies were performed to explore the interaction mechanisms of identified compounds in LPM with target enzymes. LPM demonstrated significant antioxidant activity in DPPH (IC50 = 29.08 µg/mL) and FRAP (1214.67 µM FeSO4/g extract) assays. Plant extract showed significant inhibition of collagenase, elastase, hyaluronidase, and tyrosinase (IC50 = 52.68, 43.76, 31.031, and 37.13 µg/mL, respectively). The extract demonstrated significant COX-2 and 5-LOX inhibition capacity with IC50 values of 8.635 and 10.851 µg/mL, respectively. The molecular docking study revealed the high potential of the identified compounds to bind to the active sites of enzymes crucially involved in the skin aging process. ADMET analysis of the compounds revealed their good absorption, distribution, and metabolism profiles, and they were found to be safe as well. Study findings suggest L. procumbens as a promising source for the development of natural skin anti-aging and antioxidant compounds. This, in turn, may facilitate its incorporation into cosmetic formulations after further investigation.

Abstract
The Camellia tetracocca Zhang is a rare and ancient plant, exclusively found in the vicinity of Puan County, Guizhou Province, China. According to leaf color, two distinct variations have been identified: purple C. tetracocca Zhang (PCTZ) and green C. tetracocca (GCTZ). This research was conducted to investigate the antioxidant activities and chemical compositions of different edible parts of PCTZ and GCTZ. Antioxidant activity was evaluated using DPPH, ABTS, HSA, and T-AOC assays, while the content of compounds was determined by HPLC. The findings demonstrated that the antioxidant capacity of PCTZ leaves is significantly superior to that of GCTZ leaves. Notably, theacrine, a rare compound, contains up to 2.075% in PCTZ leaves, indicating potential as a novel natural antidepressant and antioxidant. In conclusion, PCTZ is a distinctive tea beverage and a valuable genetic material for tea tree breeding due to its high theacrine and low caffeine characteristics.

Simultaneous measurement of duloxetine hydrochloride and avanafil at dual-wavelength using novel ecologically friendly TLC-densitometric method: application to synthetic mixture and spiked human plasma with evaluation of greenness and blueness. BMC Chem 2024; 18:92. [PMID: 38702832 PMCID: PMC11067093 DOI: 10.1186/s13065-024-01195-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Accepted: 04/18/2024] [Indexed: 05/06/2024] Open
Abstract
The simultaneous assay of duloxetine hydrochloride (DLX) and avanafil (AVN) in their pure forms, synthetic mixtures, and spiked human plasma was achieved using a novel, eco-friendly, sensitive, and specific HPTLC methodology that have been established and validated. Measuring the levels of co-administered antidepressants and sexual stimulants in biological fluids is an important step for individuals with depression and sexual problems. Separation was performed successfully using pre-coated silica gel 60-F254 as a stationary phase and a mobile phase composed of methanol, acetone, and 33% ammonia (8:2:0.05, v/v/v). Compact bands were produced by the optimized mobile phase that was chosen for development (Rf values were 0.23 and 0.75 for DLX and AVN, individually) after dual-wavelength detection for DLX and AVN at 232 and 253 nm, respectively. The results of polynomial regression analysis were exceptional (r = 0.9999 for both medicines) over concentration ranges of 5-800 and 10-800ng/spot for DLX and AVN, respectively. The quantitation limits were 4.69 and 9.53 ng/spot (0.31 and 0.94 µg/mL), whereas the detection limits were 1.55 and 3.15 ng/spot (0.63 and 1.91 µg/mL), for DLX and AVN, respectively. The International Council for Harmonization (ICH) criteria served as the basis for validating the established approach. Moreover, the proposed technique was evaluated in terms of greenness using four contemporary ecological metrics: The Analytical Greenness software (AGREE), the Green Analytical Procedure Index (GAPI), Eco-Scale, and the National Environmental Method Index (NEMI). Additionally, the Blue Applicability Grade Index (BAGI), a newly developed tool for evaluating the practicality (blueness) of procedures, was taken into consideration when evaluating the sustainability levels of the established approach.

Exploring the effective compounds and potential mechanisms of Shengxian Decoction against coronary heart disease by UPLC-Q-TOF/MS and network pharmacology analysis. Heliyon 2024; 10:e29558. [PMID: 38681620 PMCID: PMC11046127 DOI: 10.1016/j.heliyon.2024.e29558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 04/08/2024] [Accepted: 04/10/2024] [Indexed: 05/01/2024] Open
Abstract
As a well-known classical Chinese medicine prescription, Shengxian Decoction (SXD) has been applied for a century to treat cardiovascular diseases, especially coronary heart disease (CHD), but the potentially effective compounds and underlying mechanisms remain unclear. With ultra-performance liquid chromatography-quadrupole-time of flight-mass spectrometry (UPLC-Q-TOF/MS) and network pharmacology analysis, the potential effective compounds of SXD and their pharmacological mechanisms against CHD were identified and revealed. 57 effective compounds with favorable pharmacokinetic characteristics and biological activities were screened through UPLC-Q-TOF/MS analysis, database and literature mining, interacting with 96 CHD-related targets to support potential synergistic therapeutic actions. Systematic analysis of the PPI network and microarray data further revealed six core targets, including TNF, IL-1β, IL-6, TP53, VEGFA and PTGS2, which were mainly involved in fluid shear stress and atherosclerosis, lipid and atherosclerosis, PI3K-Akt signaling pathway et al. Moreover, the proposed contribution indexes of effective compounds indicated these compounds, including isoferulic acid, quercetin, calycosin, ferulic acid, kaempferol, calycosin 7-O-glycoside, formononetin, astragaloside IV and saikosaponin D, as the core compounds of SXD. The molecular docking results confirmed that those core compound-target pairs exhibited strong binding energy. Furthermore, we validated that SXD significantly alleviated myocardial tissue injury in CHD rats and reversed H/R-induced decreases in H9c2 cell viability by attenuating the production of TNF, IL-6 and IL-1β, and reducing cardiomyocyte apoptosis via down-regulating the TP53, caspase3 and cytochrome C mRNA expression levels as well as caspase3, caspase9 and cytochrome C protein expression levels according to RT-qPCR and Western blot results. Our findings explained the pharmacological mechanisms underlying the effectiveness of SXD in the treatment of CHD, and laid a foundation for future basic and clinical research of SXD.

Abstract
Due to the potential harm to human health, heavy metal deposition in agricultural products has gained importance throughout the world. Excessive use of agrochemicals and poultry wastes dramatically increased during the cultivation processes of rapidly growing vegetables without maintaining authorized guidelines. It happens due to the availability and low cost of these materials and higher production of the vegetables. Higher levels of heavy metals, especially Arsenic (As), Lead (Pb), Chromium (Cr), and Cadmium (Cd) contamination in food have detrimental effects on human health as well as the environmental ecosystems. This study revealed the profile of the heavy metals in the fast-growing vegetable called red amaranth (Amaranthus cruentus) due to the frequent use of poultry manure. We collected a total of 75 samples of red amaranth, water, and soil from five villages of five different unions at Ishwardi upazila in Bangladesh, and we analyzed the contamination levels of As, Pb, Cr, and Cd in them. Except for the As, we found that the accumulation levels of Pb, Cr, and Cd in samples crossed the highest permissive limit compared to FAO/WHO standards. Results suggested that daily intake of red amaranth in this area is alarming to human health due to the detrimental effects of these heavy metals.

Abstract
The Niger Delta environment is under serious threat due to heavy metal pollution. Many studies have been conducted on the heavy metal contamination in soils, water, seafood and plants in the Niger Delta ecosystem. However, there is a lack of clear understanding of the health consequences for people and strategies for attaining One Health, and a dispersion of information that is accessible. The study focused on investigating the contamination levels, distributions, risks, sources and impacts of heavy metals in selected regions of the Niger Delta. Prior studies revealed that the levels of certain heavy metals, including Cd, Pb, Cu, Cr, Mn, Fe and Ni, in water, sediment, fish and plants in most Niger Delta ecosystems were higher than the acceptable threshold attributed to various anthropogenic stressors. In the reviewed Niger Delta states, ecosystems in Rivers state showed the highest concentrations of heavy metals in most sampled sites. Groundwater quality was recorded at concentrations higher than 0.3 mg/L World Health Organization drinking water guideline. High concentrations of copper (147.915 mg/L) and zinc (10.878 mg/L) were found in Rivers State. The heavy metals concentrations were greater in bottom-dwelling organisms such as bivalves, gastropods and shrimp than in other fishery species. Heavy metal exposure in the region poses risks of communicable and non-communicable diseases. Diverse remediation methods are crucial to reduce contamination levels, but comprehensive strategies and international cooperation are essential to address the health hazards. Actively reducing heavy metals in the environment can achieve One Health objectives and mitigate disease and economic burdens.

Abstract
Infectious urolithiasis is a type of urolithiasis, that is caused by infections of the urinary tract by bacteria producing urease such as Proteus mirabilis. Lactobacillus spp. have an antagonistic effect against many pathogens by secreting molecules, including organic acids. The aim of the study was to determine the impact of Lactobacillus strains isolated from human urine on crystallization of urine components caused by P. mirabilis by measuring bacterial viability (CFU/mL), pH, ammonia release, concentration of crystallized salts and by observing crystals by phase contrast microscopy. Moreover, the effect of lactic acid on the activity of urease was examined by the kinetic method and in silico study. In the presence of selected Lactobacillus strains, the crystallization process was inhibited. The results indicate that one of the mechanisms of this action was the antibacterial effect of Lactobacillus, especially in the presence of L. gasseri, where ten times less P. mirabilis bacteria was observed, compared to the control. It was also demonstrated that lactic acid inhibited urease activity by a competitive mechanism and had a higher binding affinity to the enzyme than urea. These results demonstrate that Lactobacillus and lactic acid have a great impact on the urinary stones development, which in the future may help to support the treatment of this health problem.

Abstract
Dye and textile industries are one of the main causes of water pollution and put the environment and health of society at risk. Developing new materials to decontaminate industrial waste effluents containing dyes as pollutants is challenging due to numerous issues, including tailoring recyclable and biodegradable agents. This study focuses on applying an advanced oxidation process, electro-Fenton for the treatment of dye-containing wastewater using agar-functionalized graphene oxide-immobilized copper ferrite aerogel. The objective is therefore to determine the optimal conditions for the degradation of model pollutants methylene blue (MB). MB was oxidized and degraded through the dark-Fenton process using Agar@GO-CuFe2O4 as a new biobased catalyst. The effect of the operating parameters was then evaluated to determine the optimal conditions. The degradation process was screened for different initial concentrations of dye solution between 10 and 150 mg/l, a volume range of H2O2 between 0.5 and 2.5 ml, and different pH from 2 to 7. The results show that 99.89 % of the MB with the initial concentration of 150 ppm was degraded by 20 mg of the catalyst and 2 ml of H2O2 (30 % W/W) at 40 °C and pH = 6. Pseudo-second-order kinetics satisfactorily describes the experimental data. SYNOPSIS: The prepared catalyst can be applied to oxidize industrial effluents before they are released into the environment.

This aggregation may directly alter the soil nutrient and their fractions in soil. So, soil samples were collected from two types of forests i.e. Natural Korean pine forests (NKPF) and Korean pine plantation (KPP) in order to know the quantities of organic and inorganic Phosphorus (P) amounts in different aggregate sizes viz. >5 mm, 2-5 mm, 0.25-2 mm, <0.25 mm under forest litter and synthetic fertilizer application below the treatments as undisturbed soil (CK), removed litter (RL), altered litter (AL) while the fertilizer treatments were as control; C: (No added N and P,), L: low (5 g N m-2 a-1 + 5 g P m-2 a-1), M: medium (15 g N m-2 a-1 + 10 g P m-2 a-1) and H: high concentration (30 g N m-2 a-1 + 20 g P m-2 a-1), respectively. The results showed that H2O-Pi, NaHCO3-Pi, Residual Pi, SOC were highest retained in larger soil aggregates (>5 mm) and decreased with the decreasing aggregate size, while other variables, i.e., NaOH-Pi, NaHCO3-Po, pH and T-N were not affected in aggregate size. H2O-Pi (48 ppm), NaHCO3-Pi (68 ppm), NaHCO3-Po (80 ppm), NaOH-Po (623 ppm), HCL-Po (67 ppm), SOC (20.36 ± 1.6) was estimated in medium fertilizer treatment. PCA analysis showed that spread/variance of data points on F1 (62.90%) is more than spread/variance of data points on F2 (57.74%) in NKPF and KPP, respectively, while correlation matrix showed high correlation between H2O-Pi and NaOH-Pi (0.63) and H2O-Pi and NaHCO3-Pi (0.63) while a strong negative correlation was present between Res-Pi and Po (-0.61). Moreover, litter inputs increased the organic-P fractions in soil particularly at medium treatment.

Abstract
Lorlatinib (LRL) is the first drug of the third generation of anaplastic lymphoma kinase (ALK) inhibitors used a first-line treatment of non-small cell lung cancer (NSCLC). This study describes, for the first time, the investigations for the formation of a charge transfer complex (CTC) between LRL, as electron donor, with chloranilic acid (CLA), as a π-electron acceptor. The CTC was characterized by ultraviolet (UV)-visible spectrophotometry and computational calculations. The UV-visible spectrophotometry ascertained the formation of the CTC in methanol via formation of a new broad absorption band with maximum absorption peak (λmax) at 530 nm. The molar absorptivity (ε) of the complex was 0.55 × 103 L mol-1 cm-1 and its band gap energy was 2.3465 eV. The stoichiometric ratio of LRL/CLA was found to be 1:2. The association constant of the complex was 0.40 × 103 L mol-1, and its standard free energy was -0.15 × 102 J mole-1. The computational calculation for the atomic charges of an energy minimized LRL molecule was conducted, the sites of interaction on the LRL molecule were assigned, and the mechanism of the reaction was postulated. The reaction was adopted as a basis for developing a novel 96-microwell spectrophotometric method (MW-SPA) for LRL. The assay limits of detection and quantitation were 2.1 and 6.5 µg/well, respectively. The assay was validated, and all validation parameters were acceptable. The assay was implemented successfully with great precision and accuracy to the determination of LRL in its bulk form and pharmaceutical formulation (tablets). This assay is simple, economic, and more importantly has a high-throughput property. Therefore, the assay can be valuable for routine in quality control laboratories for analysis of LRL's bulk form and pharmaceutical tablets.

Abstract
The peels extracted from various citrus species are major source of phenols, flavonoids and anti-microbial agents. The purpose of this study was a detailed investigation of the phytochemical and pharmacological character of the ethanolic (80%), methanolic and acetone extracts of the peel of local variants of orange (lemon, grape fruit, mousami, fruiter, and shikri malta). The extracts were studied to find out the total phenolic contents (TPC), and total flavonoids (TF) present. The antioxidant activities were assessed by 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging effect, and the reducing power was determined through free radical scavenging activity (FRAP) assays. The sensitivity of four bacterial strains to peels extracts was examined by applying the diffusion disc on agar medium method. It was found that ethanol was the best extracting agent for TPC and TF in fruit peels under study. The highest TPC (21.33 ± 0.06 mg GAE/g) was quantified in orange peels, whereas fruiter contained the lowest TPC (20.40 ± 0.03 mg GAE/g) in ethanolic extract. The highest amount of TF (2.02 ± 0.08 mg QE/g) was quantified in lemon peels, whereas shikri malta contained lowest quantity of TF (1.04 ± 0.02 mg QE/g). The highest free radical scavenging activity (93.1%) of DPPH was exhibited by lemon peels, whereas the least activity (78.6%) was shown by mousami peels. Ethanolic extract of orange peels demonstrated more reducing power while showing an absorption of 1.98, followed by methanolic (1.11) and acetone (0.81) extracts. The inhibition effect of methanolic extract of lemon peels (inhibition zone = 18 mm) against B. subtilis was considerable and comparable to that of ciprofloxacin. Gas chromatography/mass spectrometry (GC/MS) was used to detect the compounds in ethanolic extract and up to 14 compounds were detected. These compounds were also assessed for their docking scores. Plausible binding modes with polyphenol oxidase and four best compounds were selected for molecular dynamics (MD) simulation to analyze their structural stability with receptor.

Gelatin/carboxymethyl cellulose edible films: modification of physical properties by different hydrocolloids and application in beef preservation in combination with shallot waste powder.

Abstract
In this work, a gelatin/carboxymethyl cellulose (CMC) base formulation was first modified by using different hydrocolloids like oxidized starch (1404), hydroxypropyl starch (1440), locust bean gum, xanthan gum, and guar gum. The properties of modified films were characterized using SEM, FT-IR, XRD and TGA-DSC before selecting of best-modified film for further development with shallot waste powder. SEM images showed that the rough or heterogeneous surface of the base was changed to more even and smooth depending on the hydrocolloids used while FTIR results demonstrated that a new NCO functional group non-existent in the base formulation was found for most of the modified films, implying that the modification led to the formation of this functional group. Compared to other hydrocolloids, the addition of guar gum into the gelatin/CMC base has improved its properties such as better color appearance, higher stability, and less weight loss during thermal degradation, and had minimal effect on the structure of resulting films. Subsequently, the incorporation of spray-dried shallot peel powder into gelatin/CMC/guar gum was conducted to investigate the applicability of edible films in the preservation of raw beef. Antibacterial activity assays revealed that the films can inhibit and kill both Gram-positive and Gram-negative bacteria as well as fungi. It is noteworthy that the addition of 0.5% shallot powder not only effectively decelerated the microbial growth but also destroyed E. coli during 11 days of storage (2.8 log CFU g-1) and the bacterial count was even lower than that of uncoated raw beef on day 0 (3.3 log CFU g-1).

Abstract
The scientific community has continued to pay particular attention to potentiometric sensors based on ion-selective membrane sensors as an energy-efficient, easy-to-use method suitable for microfabrication. To this end, potentiometric ion-selective sensors were used as an alternative green analytical instrument. Three distinct sensors relying on various ionophores were built and assessed. A cationic exchanger, tetra phenyl borate, was used in the polyvinyl chloride polymeric plasticized matrix using di octyl phthalate, where α, β, and γ cyclodextrins were utilized as ionophores. A comparative potentiometric analysis was carried out using three ion-selective sensor designs: α, β, and γ cyclodextrins sensors. β-Cyclodextrin significantly reduced the detection limit and improved the discriminative performance of mebeverine hydrochloride (MBV) in the pharmaceutical dosage form over α- and γ-cyclodextrins in the presence of other interfering chemicals. Additionally, a significant connection was made between the practical perspective and a theoretical investigation based on computational research. Nernstian potentiometric results for the optimum sensor were obtained for MBV in the range of concentrations 1.0 × 10-2 to 1.0 × 10-6 M, its slope was -58.70 ± 0.12 mV per decade with lower detection limits 4.50 × 10-7 M. This computational molecular docking investigation clarified that the binding sites and modes were in good agreement with the experiment results. This investigation was applied to expect the interaction between MBV and the proposed sensors to ensure which ionophores were the best for MBV.

Abstract
Between June 2018 and April 2019, a sampling campaign was carried out to collect PM2.5, monitoring meteorological parameters and anthropogenic events in the Sartenejas Valley, Venezuela. We develop a logistic model for PM2.5 exceedances (≥ 12.5 µg m-3). Source appointment was done using elemental composition and morphology of PM by scanning electron microscopy coupled with energy dispersive spectroscopy (SEM-EDS). A proposal of an early warning system (EWS) for PM pollution episodes is presented. The logistic model has a holistic success rate of 94%, with forest fires and motor vehicle flows as significant variables. Source appointment analysis by occurrence of events showed that samples with higher concentrations of PM had carbon-rich particles and traces of K associated with biomass burning, as well as aluminosilicates and metallic elements associated with resuspension of soil dust by motor-vehicles. Quantitative source appointment analysis showed that soil dust, garbage burning/marine aerosols and wildfires are three majority sources of PM. An EWS for PM pollution episodes around the Sartenejas Valley is proposed considering the variables and elements mentioned.

Abstract
Methylene Blue (MB) is a dye widely used in the industrial sector and in human and veterinary pharmacology. This dye, if improperly disposed of, can cause a significant environmental impact due to its low biodegradability, as it is a stable and complex substance. Additionally, it may affect human health and generate highly toxic byproducts. Hence, the purpose of this work is to assess the removal efficiency of MB from a synthetic effluent using a ionic flocculation process. Such a process consists of the dissolution of a biodegradable anionic surfactant (obtained from soybean oil used for frying food) in the synthetic effluent and the subsequent addition of calcium to the system. The addition of Ca leads to the formation of insoluble surfactant flocs with a high capacity to adsorb organic pollutants. The FTIR testing showed the presence of OH− and C=O groups in the surfactant flocs, which favor the removal of MB by an adsorption process. The maximum adsorption capacity of MB was 101.38 mg g−1. The process is in fact a chemisorption and has an exothermic nature. Desorption studies showed a desorption efficiency of up to 47.81% using an ethanol 1:2 solution. An MB removal efficiency of up to 93.71% was attained in just 0.5 min for an initial MB concentration of 100 mg L−1, showing that ionic flocculation is a very fast and effective process for the treatment of effluents. Ionic flocculation is a simple, inexpensive and highly efficient process. Biodegradable and sustainable surfactant. Fast and high removal of Methylene Blue (0.5 min–93.71%). Process of exothermic nature.

Abstract
Remdesivir (REM) is an adenosine triphosphate analog antiviral drug that has received authorization from European Commission and approval from the U.S. Food and Drug Administration for treatment of coronavirus disease 2019 (Covid-19). This study, describes, for the first time, the synthesis of a novel charge transfer complex (CTC) between REM, as electron donor, with chloranilic acid (CLA), as π electron acceptor. The CTC was characterized using different spectroscopic and thermogravimetric techniques. UV-visible spectroscopy ascertained the formation of the CTC in methanol via formation of a new broad absorption band with maximum absorption peak (λmax) at 530 nm. The molar absorptivity (ε) of the complex was 3.33 × 103 L mol-1 cm-1 and its band gap energy was 1.91 eV. The stoichiometric ratio of REM:CLA was found to be 1:1. The association constant of the complex was 1.11 × 109 L mol-1, and its standard free energy was 5.16 × 104 J mole-1. Computational calculation for atomic charges of energy minimized REM was conducted, the site of interaction on REM molecule was assigned and the mechanism of the reaction was postulated. The solid-state CTC was further characterized by FT-IR and 1H NMR spectroscopic techniques. Both FT-IR and 1H NMR confirmed the formation of the CTC and its structure. The reaction was adopted as a basis for developing a novel 96-microwell spectrophotometric method (MW-SPA) for REM. The assay limits of detection and quantitation were 3.57 and 10.83 µg/well, respectively. The assay was validated, and all validation parameters were acceptable. The assay was implemented successfully with great precision and accuracy to the determination of REM in its bulk form and pharmaceutical formulation (injection). This assay is simple, economic, and more importantly, has high throughput property. Therefore, the assay can be valuable for routine in quality control laboratories for analysis of REM's bulk form and pharmaceutical injection.

Abstract
An aminoglycoside antibiotic, amikacin, is used to treat severe and recurring bacterial infections. Due to the absence of a chromophore, however, amikacin must be extensively derivatized before being quantified, both in analytical and bioanalytical samples. In this study, for the first time, we developed a simple and sensitive method for measuring amikacin sulfate by spectrofluorimetry using a 96-well plate reader, based on the design of the experiment's approach. To develop a robust and reproducible spectrofluorimetric method, the influence of essential attributes, namely pH of the buffer, heating temperature, and concentration of reagents, were evaluated by univariate analysis followed by multivariate analysis (central composite design). ICH guidelines were used to validate the optimized method. The developed technique is linear from 1.9 to 10 μg/mL with a regression coefficient of 0.9991. The detection and quantification limits were 0.649 μg/mL and 1.9 μg/mL, respectively. For the developed method, both intra- and inter-day precision (%RSD) were below 5%. Using the method, amikacin concentrations were quantified in prepared amikacin liposomes and commercial formulations of Amicin®. The developed method greatly reduces sample volume and is a rapid, high throughput microplate-based fluorescence approach for the convenient and cost-effective measurement of amikacin in pharmaceutical formulations. In comparison to previously published approaches, the suggested method allowed for quick analysis of a high number of samples in a short amount of time (96 samples in 125 seconds), resulting in an average duration of analysis of 1.3 seconds per sample.

Synthesis, spectroscopic and computational studies on hydrogen bonded charge transfer complex of duvelisib with chloranilic acid: Application to development of novel 96-microwell spectrophotometric assay. SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2022; 264:120287. [PMID: 34455386 DOI: 10.1016/j.saa.2021.120287] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Revised: 08/01/2021] [Accepted: 08/14/2021] [Indexed: 06/13/2023]
Abstract
Duvelisib (DUV) is a is a small-molecule with inhibitory action for phosphoinositide 3-kinase (PI3K). It has been recently approved for the effective treatment of chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL). Novel charge transfer complex (CTC) between DUV, as electron donor, with chloranilic acid (CLA), as π electron acceptor has been synthesized and characterized using different spectroscopic and thermogravimetric techniques. UV-visible spectroscopy ascertained the formation of the CTC in different solvents of varying polarity indexes and dielectric constants via formation of new broad absorption band with maximum absorption peak (λmax) in the range of 488-532 nm. The molar absorptivity of the CTC was dependent on the polarity index and dielectric constant of the solvent; the correlation coefficients were 0.9955 and 0.9749, respectively. The stoichiometric ratio of DUV:CLA was 1:1. Electronic spectral analysis was conducted for characterization of the complex in terms of its electronic constants. Computational calculation for atomic charges of energy minimized DUV was conducted and the site of interaction on DUV molecule was assigned. The solid-state CTC of DUV:CLA (1:1) was synthesized, and its structure was characterized by UV-visible, mass, FT-IR, and 1H NMR spectroscopic techniques. Both FT-IR and 1H NMR confirmed that both CT and hydrogen bonding contributed to the molecular composition of the complex. The reaction was adopted as a basis for developing a novel 96-microwell spectrophotometric assay (MW-SPA) for DUV. The assay limits of detection and quantitation were 0.57 and 1.72 µg/well, respectively. The assay was validated and all validation parameters were acceptable. The method was implemented successfully with great precision and accuracy to the analysis of the DUV in its bulk and capsules.

Abstract
BACKGROUND Ganoderma lucidum (G. lucidum) is one of China's traditional medicinal materials. G. lucidum polysaccharide has a wide range of promising pharmacological applications. However, there are many kinds of G. lucidum and they contain different kinds of polysaccharides. The biological mechanism through which Ganoderma lucidum polysaccharides (GLP) is able to protect human skin fibroblasts (HSFs) from H2O2-induced oxidative damage is still unclear. METHODS Six polysaccharides were obtained from G. lucidum to evaluate their free radical scavenging ability (DPPH free radical, ABTS free radical, hydroxyl-free radical, superoxide anion-free radical) in vitro, and their protective and reparative effects on oxidative damage induced by H2O2 in human skin fibroblasts. One polysaccharide was selected to detect oxidative damage markers and gene expression in the Keap1-Nrf2/ARE signaling pathway in HSFs. RESULTS All six polysaccharides showed the ability to scavenge free radicals and enhance the tolerance of human skin fibroblasts to H2O2 damage. Among them, GLP1 was selected and separated into two components (GLP1I and GLP1II). The results showed that GLP1, GLP1I and GLPII could significantly reduce the levels of reactive oxygen species (ROS) and malondialdehyde (MDA). The protective effect of GLP1II was stronger than that of positive control vitamin C. In addition, GLP1, GLP1I and GLP1II could significantly increase the levels of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px). And GLP1I works best in both ways. Meanwhile, Nrf2, a key regulator of keAP1-NRF2/ARE signaling pathway, was activated, while Keap1, a negative regulator, was inhibited, thus promoting the expression of downstream antioxidant enzyme genes (GSTs, GCLs, Nqo1, and Ho-1). CONCLUSION The results showed that GLP could protect human skin fibroblasts from oxidative damage caused by H2O2 peroxide by enhancing enzyme activity and activating Keap1-Nrf2/ARE signaling pathway. GLP will act as a natural antioxidant to protect the skin from oxidative stress damage.

Abstract
Crizotinib (CZT) is a potent and selective tyrosine kinase inhibitor used for treatment of non-small cell lung cancer (NSCLC). The development of high-throughput assays for its quality control (QC) is very essential to assure its therapeutic benefits. CZT molecule has multiple electron-donating atoms that can contribute to the formation of colored charge-transfer (CT) complex with iodine as σ-electron acceptor and with 2,5-dichloro-3,6-dihydroxy-1,4-benzoquinone (CHBQ) and 7,7,8,8-tetracyanoquinodimethane (TCNQ) as π-electron acceptors. These reactions were prospective basis for development of three innovative 96-microwell-based spectrophotometric assays for CZT. The reactions of CZT with iodine, CHBQ and TCNQ were performed in 96-microwell assay plates and absorbances of the CT complexes were measured by microwell absorbance reader at their corresponding maximum absorption peaks. The measured absorbances were correlated with the CZT concentrations in its sample solutions. Beer's law was obeyed with excellent correlation coefficients in the range of 0.5-30, 2-500, and 5-500 µg mL-1 for assays using iodine, CHBQ and TCNQ, respectively. The limits of detection were 2.17, 0.85 and 6.23 µg mL-1 for assays using iodine, CHBQ and TCNQ, respectively. The validation studies confirmed the accuracy and precision of all the proposed assays. The assays were successfully applied in the determination of CZT in Xalkori capsules. The proposed assays have very simple procedures to run in QC laboratories. Also, both assays enable analyst to process large number of samples and use of very small volumes of the organic solvent (ecofriendly and inexpensive).

Abstract
Background Linifanib (LFB) is a multi-targeted receptor tyrosine kinase inhibitor used in the treatment of hepatocellular carcinoma and other types of cancer. The charge-transfer (CT) interaction of LFB is important in studying its receptor binding mechanisms and useful in the development of a reliable CT-based spectrophotometric assay for LFB in its pharmaceutical formulation to assure its therapeutic benefits. Purpose The aim of this study was to investigate the CT reaction of LFB with 2,3-dichloro-3,5-dicyano-1,4-benzoquinone (DDQ) and its application in the development of a novel 96-microwell spectrophotometric assay for LFB. Methods The reaction was investigated, its conditions were optimized, the physicochemical and constants of the CT complex and stoichiometric ratio of the complex were determined. The solid-state LFB-DDQ complex was synthesized and its structure was analyzed by UV-visible, FT-IR, and 1H-NMR spectroscopic techniques, and also by the computational molecular modeling. The reaction was employed in the development of a novel 96-microwell spectrophotometric assay for LFB. Results The reaction resulted in the formation of a red-colored product, and the spectrophotometric investigations confirmed that the reaction had a CT nature. The molar absorptivity of the complex was linearly correlated with the dielectric constant and polarity index of the solvent; the correlation coefficients were 0.9526 and 0.9459, respectively. The stoichiometric ratio of LFB:DDQ was 1:2. The spectroscopic and computational data confirmed the sites of interaction on the LFB molecule, and accordingly, the reaction mechanism was postulated. The reaction was utilized in the development of the first 96-microwell spectrophotometric assay for LFB. The assay limits of detection and quantitation were 1.31 and 3.96 μg/well, respectively. The assay was successfully applied to the analysis of LFB in its bulk and tablets with high accuracy and precision. Conclusion The assay is simple, rapid, accurate, eco-friendly as it consumes low volumes of organic solvent, and has high analysis throughput.

Abstract
Background:
Linifanib (LFB) is a tyrosine kinase inhibitor with antineoplastic activity.
The existing methods for the analysis of LFB in bulk and dosage forms do not meet the requirements
of quality control (QC) analysis.
Objective:
The present study was devoted to the development of two methods with high throughputs
for determination of LFB. These methods are 96-microwell plate assay with microplate fluorescence
reader (MWP-FR) and high-performance liquid chromatography with fluorescence detection
(HPLC-FD).
Methods:
The MWP-FR assay was carried out in white opaque 96-well assay plates and the native
fluorescence signals of LFB were measured at 360 nm for excitation and 500 nm for emission. In
the HPLC-FD, the chromatographic separation of LFB and quinine sulphate (QS) as internal standard
(IS) was performed on µ-Bondapack CN HPLC column using a mobile phase consisting of
acetonitrile:water (60:40, v/v) pumped at a flow rate of 1 ml/min in an isocratic mode. The fluorescence
detector was set at 350 nm for excitation and 454 nm for emission.
Results:
The linear ranges of the MWP-FR and HPLC-FD were 1-12 µg/well and 10-500 ng/ml, respectively.
The limits of detection were 0.85 µg/well and 8.24 ng/ml for MWP-FR and HPLC-FD,
respectively. Both MWP-FR and HPLC-FL methods were successfully applied for the determination
of LFB in both bulk and tablets.
Conclusion:
Both methods have high analytical throughputs, they are suitable for use in QC laboratories
for analysis of large numbers of LFB samples, and are environmentally friendly as they consume
low volumes of chemicals and solvents.

Abstract
Abstract
Food industries seek to incorporate nutritious ingredients as they could bring added value to the final food products. One of the most interesting options is that sea buckthorn contains high concentrations of vitamin C, carotenoids, tocopherols, and other bioactive compounds, in addition to the unique lipid profile in the berry pulp, seed, and peel. This review summarizes the state-of-the-art of potential applications of sea buckthorn within the food and feed industry based on previously described applications. Products such as cheese, yoghurt or beverages already benefit from its application. Moreover, using sea buckthorn in feed products also derives into higher quality final products (e.g. meat quality, egg quality). Poultry, pig, and fish farming have been studied for that purpose. Despite all the accumulated articles depicted in the present review, the use of this fruit in food product formulation is nowadays scarce. New options for food product development with sea buckthorn are herein discussed.

Abstract
Corticosteroids are a class of hormones released by the adrenal cortex, which includes glucocorticoids and mineralocorticoids. Glucocorticoids have an important role in the metabolism of carbohydrates, proteins and calcium and effective anti-inflammatory and immunosuppressive activity. Due to their intense immunomodulatory and anti-inflammatory activity, glucocorticoids are used in the treatment of various inflammatory, malignant, allergic conditions such as rhinitis, asthma, dermatological, rheumatic, ophthalmic and neurological diseases, as well as after organ transplants. They are the most widely prescribed drugs in the world. The objective of this review is to provide an overview of the analytical methods in pharmaceutical matrices for determination of corticosteroids. In this study, the predominance of liquid chromatography methods for the analysis of corticosteroids from pharmaceutical products is evident for both liquid and semisolid dosage forms as well as for solids. The same can be said for topical, oral and parenteral formulations. Methods such as spectrophotometry are also used, but given the advantages of chromatographic methods such as better selectivity and sensitivity, they have become the choice for analysis of these drugs, however, most methods still do not meet the credentials of "green chemistry."

Abstract
Quantitative structure-activity relationship (QSAR) analysis has been carried out with a series of 107 anti-HIV HEPT compounds with antiviral activity, which was performed by chemometrics methods. Bi-dimensional images were used to calculate some pixels and multivariate image analysis was applied to QSAR modelling of the anti-HIV potential of HEPT analogues by means of multivariate calibration, such as principal component regression (PCR) and partial least squares (PLS). In this paper, we investigated the effect of pixel selection by application of genetic algorithms (GAs) for the PLS model. GAs is very useful in the variable selection in modelling and calibration because of the strong effect of the relationship between presence/absence of variables in a calibration model and the prediction ability of the model itself. The subset of pixels, which resulted in the low prediction error, was selected by genetic algorithms. The resulted GA-PLS model had a high statistical quality (RMSEP = 0.0423 and R2 = 0.9412) in comparison with PCR (RMSEP = 0.4559, R2 = 0.7929) and PLS (RMSEP = 0.3275 and R2 = 0.0.8427) for predicting the activity of the compounds. Because of high correlation between values of predicted and experimental activities, MIA-QSAR proved to be a highly predictive approach.

Abstract
BACKGROUND Cisplatin (CP) or cis-diammine dichloroplatinum (II) is a platinum based standard antineoplastic drug which is used against variety of solid tumors and neoplasms. The present study aimed to evaluate the shielding effects of rutin against CP induced testicular toxicity in rats. METHODS 28 male rats were divided into four groups. First group was given saline orally while second group received intra-peritoneal (i.p) injection of cisplatin (7 mg/kg) on day first and received saline for next 13 days. Third group received i.p injection of cisplatin at day one and treated with rutin (75 mg/kg) orally for next 13 days. Fourth group was treated with rutin orally for 13 days. Animals were sacrificed on 14th day and reproductive organs were analyzed for various parameters. RESULTS Cisplatin treatment resulted in a significant decrease in daily sperm production, decrease in head length and % DNA in head, reduction of epithelial cell height, tubular diameter, reduction of the number of spermatogonia, spermatocytes and spermatids, increase in the thiobarbituric acid reactive substances (TBARS) and oxidative stress in testicular tissues, and change of the intra-testicular testosterone concentrations. Rutin co-treatment resulted in reversing cisplatin effect on DNA damage, sperm count, histological and biochemical parameters. CONCLUSION These results indicated that rutin co-treatment could ameliorate cisplatin-induced reproductive toxicity in male rats.

Abstract
Keeping the sources of pollution such as chromium (Cr) under a safe limit is a daunting challenge due to the negative impact of heavy metal bioaccumulation in vegetation and the concomitant human health exposure. We took a closer look at Sonchus asper by cultivating in the green house. It resulted in 80% germination when cultivated over nine different soils collected from the tannery dump site. The biochemical analytical techniques such as mass spectrometry indicated significant bioaccumulation of Cr in the plant tissue. As per the ICP-MS analysis, this annual herb resulted in the accumulation of 601 mg kg-1 of total Cr with 212 mg kg-1 in its shoot from soil samples containing up to 41 mg kg-1 of hexavalent Cr. The energy dispersive X-ray (EDX) spectroscopy of S. asper revealed a higher level of S element indicating a sulfate-Cr binding relation. Elevated content of Cr in soil (73,721 ± 65 mg kg-1) caused biochemical changes in the shoot of S. asper as indicated by the disappearance of Fourier transform infrared spectroscopy (FTIR) bands at 935 and 872 cm-1 and further revealing aliphatic -CH2 appearing as anti-symmetry νa(CH2) and symmetric vibration νs(CH2) at the band of 2920 and 2850 cm-1, respectively.

Abstract
A novel method of on-line 2,2'-Azinobis-(3-ethylbenzthiazoline-6-sulphonate)-Capillary Electrophoresis-Diode Array Detector (on-line ABTS+-CE-DAD) was developed to screen the major antioxidants from complex herbal medicines. ABTS+, one of well-known oxygen free radicals was firstly integrated into the capillary. For simultaneously detecting and separating ABTS+ and chemical components of herb medicines, some conditions were optimized. The on-line ABTS+-CE-DAD method has successfully been used to screen the main antioxidants from Shuxuening injection (SI), an herbal medicines injection. Under the optimum conditions, nine ingredients of SI including clitorin, rutin, isoquercitrin, Quercetin-3-O-D-glucosyl]-(1-2)-L-rhamnoside, kaempferol-3-O-rutinoside, kaempferol-7-O-β-D-glucopyranoside, apigenin-7-O-Glucoside, quercetin-3-O-[2-O-(6-O-p-hydroxyl-E-coumaroyl)-D-glucosyl]-(1-2)-L-rhamnoside, 3-O-{2-O-[6-O-(p-hydroxyl-E-coumaroyl)-glucosyl]}-(1-2) rhamnosyl kaempfero were separated and identified as the major antioxidants. There is a linear relationship between the total amount of major antioxidants and total antioxidative activity of SI with a linear correlation coefficient of 0.9456. All the Relative standard deviations of recovery, precision and stability were below 7.5%. Based on these results, these nine ingredients could be selected as combinatorial markers to evaluate quality control of SI. It was concluded that on-line ABTS+-CE-DAD method was a simple, reliable and powerful tool to screen and quantify active ingredients for evaluating quality of herbal medicines.

Abstract
The present study is designed to evaluate the antimicrobial, antioxidant and anticancer activities of Rhizophora apiculata. Initially, the phenolic and flavonoid content was quantified in solvent extracts, and gallic acid and rutin were used as a control, respectively. Further, antimicrobial and minimal inhibitory activities of different solvent extracts were assessed against human clinical pathogenic bacteria, and the results showed that butanol and methanol extract has potential antimicrobial activity. FTIR analysis of solvent extracts showed the presence of phenolic compounds at 3409-3430 cm-1 that actively involved in various applications including antioxidant and anticancer activities. The in vitro antioxidant activity of solvent extracts showed excellent antioxidant potential, about 84% of DPPH free-radical scavenging, 76% of hydrogen peroxide, 82% of hydroxyl radical scavenging, and 80% of reducing power. Two-way ANOVA analysis showed that the highly significant effect of antioxidant activity depends on the concentration of extracts. The DNA protection efficiency of extracts against oxidative damage was confirmed by DNA nicking assay using bacterial DNA. The methanol extract effectively inhibited the growth and induces the apoptosis through ROS generation and sensitizes the mitochondrial membrane potential of A549 lung cancer cells. Taken together, the results showed that the solvent extracts of R. apiculata could be potential antioxidant and anticancer agents.

Abstract
Ready-to-drink (RTD) ice tea is a ready prepared tea, produced from green and black tea originating from same plant Camellia sinensis. The objective of this study was to determine the effect of prebiotics [galacto-oligosaccharide (GOS), fructo-oligosaccharide (FOS), and inulin] or synbiotic ingredients (GOS, FOS, inulin, and Lactobacillus acidophilus) on the sensory properties and consumer acceptability of RTD. The quality of green tea extract (GTE) and black tea extract (BTE) was improved with pretreatment of cellulase and pectinase enzymes. The combined enzymatic extraction amplified total extractives up to 76% in GTE and 72% in BTE. Total polyphenol was found to be enhanced to 24% in GTE and 19% in BTE. GTE was further selected for development of RTD in two different formats; synbiotic RTD and prebiotic RTD premix and analyzed for sensory attributes (colour, aroma, taste, and acceptability). Synbiotic RTD was also evaluated for stability over a period of 28 days at 4 °C. Synbiotic RTD developed an unpleasant flavor and aroma during the shelf life. Premix format of RTD developed using spray drying was reconstituted and found to be functionally and sensorially acceptable.

Abstract
Supplementation of broiler chicken diets with resin rich in bioactive components, such as different boswellic acids, could improve productivity, chemical composition, and nutritive value of produced meat. The aim of the study was to assess the effect of different levels of Boswellia serrata (BSR) supplementation in broiler chicken diet on the basic chemical composition and the Ca, P, Mg, Fe, Zn, and Cu contents in the breast and drumstick muscles and liver. The analyses involved 200 Ross 308 chickens. The broiler chickens were fed with diets containing 0 (BSR0), 1.5 (BSR1.5), 2 (BSR2), and 2.5% (BSR2.5) of B. serrata resin. The supplementation of broiler chicken diets with 2.5% (BSR2.5) decreased linearly the ether extract in breast and drumstick muscles and the calorific value in drumstick muscles (P < 0.05). An increased level of Ca in the breast and drumstick muscles (control vs. BSR diets, linear, P < 0.05) and in the liver (control vs. BSR diets, quadratic, P < 0.05) as well as Mg in the drumstick muscles and liver (control vs. BSR diets, linear, P < 0.05) was noted in the BSR2 and BSR2.5 chicken groups. The BSR supplementation reduced Cu (in the breast and drumstick muscles and liver) (P < 0.05) and Zn retention (in the drumstick muscles) (C vs. BSR, linear, P < 0.05). B. serrata resin can be considered a good feed additive with a positive impact on the dietary value of poultry meat.

Abstract
Mosquitoes act as key vector for transmission of devastating parasites and pathogens which affect millions of people globally. In this research, the green synthesis of silver nanoparticles of Cassia fistula fruit pulp as an innovative and operative tool against vector mosquitoes is presented. Silver nanoparticles were characterized by a series of techniques including Fourier transform infrared spectroscopy, Transmission Electron Microscope and confirmed by Scanning Electron Microscope, UV-Vis spectrophotometry and X-ray diffraction. Silver nanoparticles were highly effective against the larvae (I-IV instar) and pupae of Aedes albopictus and Culex pipiens pallens after 24, 48 and 72 h of treatment. Ae. albopictus had LC50 values ranging from 8.3 mg/L (I instar) to 17.3 mg/L (pupae) and LC50 ranging from 1.1 mg/L (I instar) to 19.0 mg/L (pupae) against Cx. pipiens pallens. The systemic effect of AgNPs was further assessed in the fourth instar larvae of Ae. albopictus and Cx. pipiens pallens by measuring the levels of total proteins and activity of two important marker enzymes: Acetylcholinesterase and α- and β-carboxylesterase. Overall, the findings of the study suggest that the use of Cassia fistula-fruit pulp extract mediated synthesis of silver nanoparticles can be used for controlling vector mosquitoes. This is the first report on the mosquito larvicidal and pupicidal activity of AgNPs synthesized by Cassia fistula fruit pulp and its possible mechanism of action.
