“…In the literature [ 4 , 6 , 18 , 19 , 20 ] and international standards [ 21 , 22 , 23 ], there are many methods for the determination of FAs in a milk sample. Typically, FAMEs are quantified by GC following the multi-step sample preparation procedure.…”

Determination of the fatty acid profile in milk samples is one of the most important in food analysis. There are many methodologies for FA determination. The conventional procedure for determining the FA composition of milk is isolation of fat or indirect methylation, trans-methylation, extraction of fatty acids, and analysis by gas chromatography. In this study, eight methods based on alkaline methylation were compared for the analysis of fatty acids in cow’s milk. The response factors (RF) for GC analysis using FID were calculated. For most acids, RFs were close to 1, with the exception of short-chain fatty acids (C4:0–C8:0). To facilitate the selection of the method for the determination of fatty acids in milk samples, the methods were assessed using the environmental assessment tools of the analytical procedure: the Analytical Eco-Scale, Green Analytical Procedure Index (GAPI), and Analytical Greenness for Sample Preparation (AGREEprep). The method based on direct milk methylation received the highest scores. Omitting the lipid separation step has an impact on reducing the quantity of used toxic chemicals and reagents, and produces a smaller amount of waste, a much higher throughput, and a reduced cost analysis.

Cabergoline (CAB) is effective prolactin lowering drug. Evaluation of the bioequivalence for the new test product (0.5 mg CAB film-coated tablets) in Egypt is strongly needed for approval of the drug by the official health authority. Therefore, a highly sensitive and rapid (LC–MS/MS) method was validated for CAB analysis in human plasma. CAB was extracted from plasma via diethyl ether using Quetiapine (QUE) as an internal standard. Multiple reaction monitoring (MRM) in positive ion mode was used, m/z 452.3 → 381.2 for CAB and 384.2 → 253.1 for QUE. Separation was accomplished on a reversed-phase C18. FDA procedures for the bio-analytical method were followed. The method was used in the bioequivalence study to compare the test product (0.5 mg CAB) versus Dostinex tablets, on 24 healthy Egyptian volunteers. The total analysis time was 5.5 min for each sample which permits analysis of various samples per day. The linearity range was from 2.00 to 200.00 pg/mL for CAB. LOD and LOQ were found to be 0.5 and 1.6 pg/mL, respectively. The final greenness numerical value was 0.63 using AGREE tool. The results of pharmacokinetic parameter Tmax were 2.17, and 2.33 h; for test and reference products, respectively. The generic formulation of test product is considered bioequivalent to the reference product Dostinex 0.5 mg tablets and satisfies the requirements of the Egyptian market. The merits of the method over the previous published methods are low cost; availability of cheap internal standard; rapidness; use of acetonitrile-free solvents mobile phase.

“…Remdesivir is a broad-spectrum nucleotide prodrug with an adenosine analogue [26] that is also effective against a wide range of endemic, emerging, and enzootic coronaviruses (CoV) [27,28]. These prodrugs are often more cellularly permeable and are metabolised to release nucleosides or phosphorylated nucleosides [29,30].…”

Remdesivir is a prodrug that works by imitating the nucleoside adenosine. It is an antiviral medication that has been used to treat the coronavirus. Given the severity of the condition, the medicine is critical to the therapy and accompanying research. Remdesivir is extremely important as a medicinal dose form. Remdesivir has been used with other medications in the following combinations: Remdesivir and Dexamethasone, Remdesivir and Tocilizumab, and Remdesivir and Ivermectin. To aid future study, the paper also gives a simultaneous and comparative review of the analytical investigations published in the literature for a pharmacological estimate. The extensive literature searches turned up a plethora of study publications. A complete explanation of common, hyphenated, and unique ways of analysis is given. Remdesivir analytical quantification is provided using HPLC, LCMS, UV-Visible spectroscopy, and fluorescence.
