Spider diagram with greenness evaluation metrics for assessing the new synchronous spectrofluorimetric determination of bicalutamide and resveratrol in human plasma. LUMINESCENCE 2023; 38:1996-2006.

Abstract
A simple, selective, and eco-friendly synchronous fluorescence approach was introduced for the first time for the concurrent estimation of the anticancer combination therapy of bicalutamide and resveratrol. The method relies on measuring the synchronous fluorescence spectra of bicalutamide and resveratrol at 269 and 320 nm, respectively, using Δλ of 60 nm with ethanol as a green diluting solvent. The procedure was optimized, and the method was then fully validated. Excellent linearity (R2 > 0.999) with very low detection limits (0.044 and 2.001 ng/ml) were obtained for both drugs, allowing for their analysis in human plasma. The green profile of the suggested approach was evaluated using the green solvents selecting tool (GSST), spider diagram for greenness index assessment, green analytical process index (GAPI), and Analytical GREEnness (AGREE) metric tools. These assessment metrics confirmed that the developed approach met the maximum number of green requirements, recommending its application as a green substitute for the regular analysis of the concerned drugs in human plasma. The simplicity of sample measurement enables and substantially accelerates the analysis, resulting in lower costs, enhanced procedure accuracy, and lower environmental effect.

J Chromatogr B Analyt Technol Biomed Life Sci 2022; 1198:123246.

Abstract
Controlled-release tablets and rectal suppositories of sulfasalazine (SLF) and hydrocortisone 21-acetate (HA) were prepared as recommended dosage forms for the treatment of acute episodes of ulcerative colitis, in patients who do not respond to monotherapy. A High-Performance Liquid Chromatography (HPLC) Diode-array method with a gradient elution mobile phase was developed to evaluate the production quality of both formulations (assay and dissolution profiles in gastric and intestinal fluids). Method's validation was carried out providing good linearity (r ≥ 0.9995), precision (RSD < 1.53%), recovery (96.9% - 103.7%) and limits of detection (LODSLF = 12 ng/mL, LODHA = 15 ng/mL). Experimental design and Plackett-Burman methodology was constructed to study the robustness of the analysis. In all composite substrates, a freezing lipid precipitation approach was used as purification step. The method was optimized by applying Central Composite design mode. The in-vitro/ex-vivo permeability studies of both formulations were evaluated by a Liquid Chromatography-Electron Spray Ionization Mass Spectrometry (LC-ESI/MS) +/- mode. The analysis of sulfamethazine (internal standard, SLM, m/z 279), HA (m/z 449, [M + HCOO]-), SLF (m/z 399) and its active metabolite mesalazine (MSL, m/z 154) was performed using a C18 column and gradient elution. The validation of the method met the requirements of the International Council for Harmonization (ICH) (r ≥ 0.9997, RSD ≤ 4.62%, Recovery > 95%, LODSLF = 1.28 ng/mL, LODHA = 1.07 ng/mL, LODMSL = 3.16 ng/mL). Based on the results, important conclusions were drawn concerning the role of excipients and SLF metabolism.

Methoxy terminated poly dimethylsiloxane bonded stationary phase for reversed-phase liquid chromatography. J Chromatogr A 2021; 1652:462348.

Abstract
In this work, a methoxy terminated poly dimethylsiloxane modified silica gel material was proposed as a novel stationary phase for reversed-phase liquid chromatography. With 5 μm silica gel as matrix, methoxy terminated poly dimethylsiloxane polymer was grafted by one step chemical bonding reaction. The obtained stationary phase was characterized by scanning electron microscopy, fourier transform infrared spectroscopy and element analysis. To our knowledge, this is the novel methoxy terminated poly dimethylsiloxane bonded stationary phase with good separation efficiency (42107-46988 plates/m for benzene homologues) and high stability (RSD is 0.08-5.09%). Comparing to other traditional columns of the same type, the proposed stationary phase has a wider polarity separation scale and shorter analysis time. In addition to the rapid separation of hydrophobic compound, such column also exhibited great potential in the separation of hydrophilic analytes.

Abstract
In this study, an accurate, simple, economical, precise and reproducible reversed-phase HPLC method was developed for the estimation of fusidic acid and hydrocortisone acetate, according to the International Conference on Harmonization guidelines, in a cream formulation. Chromatographic separation was achieved by isocratic elution, on a Shimadzu reversed-phased high-pressure liquid chromatography instrument, equipped with a C18 column (150 × 4.6 mm, 5 μm) and UV detector at 225 nm wavelength, using acetonitrile and 0.05% trifluoroacetic acid (60:40), as a mobile phase and diluent, at flow rate 2 ml/min and an injection volume of 20 μl. The calibration curves were acquired with concentration range 80-120% and mean percentage recoveries for hydrocortisone acetate and fusidic acid were 100.14 and 100.81%, respectively. The limits of detection was obtained as 6.0667 and 6.807 μm ml-1 and the limits of quantification were 20.204 and 20.628 μm ml-1 for hydrocortisone acetate and fusidic acid, respectively. All of the validation parameters were within the acceptance criteria, as per International Conference on Harmonization requirements, for hydrocortisone acetate and fusidic acid. This method was found to be validated, simple, rapid and applicable for the simultaneous estimation of hydrocortisone acetate and fusidic acid by reversed-phased high-pressure liquid chromatography, for routine analytical testing in quality control, with a run time of 8 min.

Stability-indicating HPLC-DAD assay for simultaneous quantification of hydrocortisone 21 acetate, dexamethasone, and fluocinolone acetonide in cosmetics. OPEN CHEM 2020.

Abstract
AbstractA rapid and specific method was developed for simultaneous quantification of hydrocortisone 21 acetate (HCA), dexamethasone (DEX), and fluocinolone acetonide (FCA) in whitening cream formulations using reversed-phase high-performance liquid chromatography. The effect of the composition of the mobile phase, analysis temperature, and detection wavelength was investigated to optimize the separation of studied components. The analytes were finally well separated using ACE Excel 2, C18 AR column having 150 mm length, 3 mm internal diameter, and 2 µm particle size at 35°C using methanol with 1% formic acid and double-distilled deionized water in the ratio of 60:40 (v/v), respectively, as the mobile phase in isocratic mode. Ten microliters of sample were injected with a flow rate of 0.5 mL/min. The specificity, linearity, accuracy, precision, recovery, limit of detection (LOD), limit of quantification (LOQ), and robustness were determined to validate the method as per International Conference on Harmonization guidelines. All the analytes were simultaneously separated within 8 min, and observed retention times of HCA, DEX, and FCA were 4.5, 5.5, and 6.9 min, respectively. The proposed method showed good linearity with the correlation coefficient, R2 = 0.999 over the range of 1–150 µg/mL for all standards. The linear regression equations were y = 12.7x + 118.7 (r = 0.999) for HCA, y = 12.9x + 106.8 (r = 0.999) for DEX, and y = 12.9x + 96.8 (r = 0.999) for FCA. The LOD was 0.25, 0.20, and 0.08 µg/mL for HCA, FCA, and DEX and LOQ was 2.06, 1.83, and 1.55 µg/mL for HCA, FCA, and DEX, respectively. The recovery values of HCA, DEX, and FCA ranged from 100.7–101.3, 102.0–102.6, and 100.2–102.0%, respectively, and the relative standard deviation for precision (intra- and interday) was less than 2, which indicated repeatability and reproducibility. The novelty of the method was described by forced degradation experimentation of all analytes in the combined form under acidic, basic, oxidative, and thermal stress. The proposed method was found to be simple, rapid, and reliable for the simultaneous determination of HCA, DEX, and FCA in cosmetics.
