Controlling the positive ion electrospray ionization of poly(ethylene glycols) when using ultra-high-performance supercritical fluid chromatography-mass spectrometry. J Sep Sci 2023; 46:e2300425. [PMID: 37609802 DOI: 10.1002/jssc.202300425] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Revised: 08/08/2023] [Accepted: 08/09/2023] [Indexed: 08/24/2023]
Abstract
Poly(ethylene glycols) are complex polymers often added to pharmaceutical formulations to improve drug solubility and delivery. One of the main challenges when using chromatographic techniques coupled to mass spectrometry is the unselective ionization of poly(ethylene glycols) oligomers. Additionally, when the chain length is large enough, multiple charged species are formed, further complicating the mass spectra and processing. This study uses the advanced oligomer separation provided by supercritical fluid chromatography with a mass spectrometry approach that selectively ionizes poly(ethylene glycols) as ammoniated molecules to simplify data analysis and facilitate batch-to-batch comparisons. Several visual representations of the response of the ionization events based on the polymer molecular weight and the repeating unit were used to elucidate trends in ionization. Evaluation of the influence of the oligomer length and end-group on the electrospray ionization of the polymer allowed the development of a process to enable selective ionization for these complex polymers.

Abstract
Nanomedicine has emerged as a field in which there are opportunities to improve the diagnosis, treatment and prevention of incurable diseases. Pulmonary arterial hypertension (PAH) is known as a severe and fatal disease affecting children and adults. Conventional treatments have not produced optimal effectiveness in treating this condition. Several reasons for this include drug instability, poor solubility of the drug and a shortened duration of pharmacological action. The present review focuses on new approaches for delivering anti-PAH drugs using nanotechnology with the aim of overcoming these shortcomings and increasing their efficacy. Solid-lipid nanoparticles, liposomes, metal-organic frameworks and polymeric nanoparticles have demonstrated advantages for the potential treatment of PAH, including increased drug bioavailability, drug solubility and accumulation in the lungs.

Abstract
Novel drug delivery system endows a beneficial method for achieving a desired drug concentration at the appropriate site in the body. The concept of targeted drug delivery has been emerged to localize the drug in the targeted tissue of interest while reducing the relative concentration of the medication in the surrounding tissues. This could be easily accomplished by using different multi-particulate dosage forms like pellets, granules, microcapsules, liposomes, beads. But the major drawbacks associated with them are the use of harsh chemicals and an elevated temperature for their preparation. Preparation of microbeads by ionotropic gelation and emulsion gelation method overcomes these problems by neither using harsh chemicals nor elevated temperature for their preparation. Thus, this can be proved to be a better alternative over other dosage forms. Several parameters were studied in terms of their morphology, particle size, encapsulation efficiency, swelling ratio, mucoadhesivity, etc. The endeavor of present article is toward presenting a wider perspective of the comprehensive knowledge available in the field of microbeads. Thus, the intent of this review is to recapitulate the relevance of microbeads.

Abstract
Polysaccharides are one of the most abundant natural polymers and their molecular structure influences many crucial characteristics-inter alia hydrophobicity, mechanical, and physicochemical properties. Vibrational spectroscopic techniques, such as infrared (IR) and Raman spectroscopies are excellent tools to study their arrangement during polymerization and cross-linking processes. This review paper summarizes the application of the above-mentioned analytical methods to track the structure of natural polysaccharides, such as cellulose, hemicellulose, glucan, starch, chitosan, dextran, and their derivatives, which affects their industrial and medical use.

Abstract
Hesperetin was effectively encapsulated into poly (d,l-lactic-co-glycolic acid) nanoparticles by using experimental design methods. A seven-factor Plackett-Burman design was used in order to determine the major process parameters. A significant linear equation, which shows the effect of each process parameter on encapsulation efficiency was developed, and then the most effective factors were determined. Further investigation and optimization was carried out by applying the three-factor three-level Box-Behnken design. Significant second-order mathematical models were developed by regression analysis of the experimental data for both responses: encapsulation efficiency and nanoparticle size. The two step experimental design allowed the synthesis of the desired nanoparticle formulations with maximum encapsulation efficiency (80.5 ± 4.9%) and minimum particle size (260.2 ± 16.5 nm) at optimum process conditions: 0.5% polyvinyl alcohol (PVA) concentration, 5.13 water:organic phase ratio, and 3.59 ml min-1 flow rate of the emulsified solution into 0.1% PVA. Furthermore, the biological activity of these optimized nanoparticles were determined with antimicrobial activity and cytotoxicity studies; results were then compared to the free hesperetin. The cytotoxicity result revealed that hesperetin and hesperetin-loaded nanoparticles were biocompatible with normal cell line L929 fibroblast cells up to 184.83 and 190.88 μg ml-1 for 24 h, and up to 133.24 and 134.80 μg ml-1 for 48 h, respectively. In the antimicrobial study, the optimized nanoparticle showed inhibition activity (minimal inhibitory concentration (MIC) values were 125 μg ml-1 for Escherichia coli, and 200 μg ml-1 for Staphylococcus aureus), while the free hesperetin did not demonstrate activity in both strains (MIC value >200 μg ml-1). These in vitro results may provide useful information for the investigation of hesperetin-loaded nanoparticles in diagnostic and therapeutic applications.

Abstract
Our research objective was to develop, characterize, and optimize stable form of nano-colloidal carrier with Eudragit-coated solid lipid nanobioparticles (SLNbp) for oral delivery of isradipine (ISR). To achieve, a three factors, i.e., lipid-to-surfactant ratio (A, % w/w), Eudragit L100 (B, % w/w), and sonication time (C, minutes) at three levels (-1 and +1 levels of quality central level) was applied to develop SLNbp using response surface methodology at constant ratio of ISR and rutin. The second-order polynomial quadratic equations of responses [R1, R2, and R3; entrapment efficiency (EE), particle size, and drug release] were constructed and also plotted response surface (two- and three-dimensional) plots. The derived polynomial equation and 2D and 3D model were showed the relationship between the responses of the selected independent variables (A, B, and C). The model validation and optimization was performed by numerical checkpoint analysis to predict the optimized solid lipid nanobioparticle formulas (ONbp 1-10). The optimized formulations prepared and during evaluation ONbp 3 has better smaller particle size (106 nm), sustainable release (95.61% up to 40 h), higher EE (97.85%), and drug content (99.92% ± 0.08%) during 3-month storage showed good stability. Therefore, its performance can be considered for further development of stable oral drug delivery system of ISR.

Abstract
Poly (lactic-co-glycolic acid) (PLGA) copolymers have been broadly used in controlled drug release applications. Because these polymers are biodegradable, they provide an attractive option for drug delivery vehicles. There are a variety of material, processing, and physiological factors that impact the degradation rates of PLGA polymers and concurrent drug release kinetics. This work is intended to provide a comprehensive and collective review of the physicochemical and physiological factors that dictate the degradation behavior of PLGA polymers and drug release from contemporary PLGA-based drug-polymer products. In conjunction with the existing experimental results, analytical and numerical theories developed to predict drug release from PLGA-based polymers are summarized and correlated with the experimental observations. © 2016 Wiley Periodicals, Inc.
