In this paper, deer oil was used as a raw material to prepare deer oil powder by microencapsulation technol. to study the potential protective activity of deer oil powder on ethanol-induced acute gastric mucosal injury in rats. The results show that the best process for preparing deer oil powder is: the solids account for 25% of the system content, the wall material Whey Milk Protein Isolate-Maltodextrin ratio is 1:5, the Sodium Stearyl Lactate-Glycerides of Monostearate and Distearate compound emulsifier content is 0.8%, the ratio is 1:1, and the deer oil accounts for 30% of the solid content, and the spray drying inlet temperature is 180掳C. Deer oil powder can reduce total stomach injury, gastric mucosal congestion area, and injury score index. Without affecting the blood lipid level, it can reduce the content of Myeloperoxidase, enhance the activity of Superoxide Dismutase and Glutathione Peroxidase, and has good antioxidant activity. Enhance the expression of defense factors Estradiol, Epidermal Growth Factor, and Somatostatin. At the same time, it reduces the levels of Interleukin-1尾 and Interleukin-6 pro-inflammatory cytokines in gastric tissue and enhances the expression of anti-inflammatory factors Interleukin-4 and Interleukin-10. These results indicate that the gastric protection mechanism of deer oil powder may be related to the enhancement of mucosal defense factors, inhibition of inflammation, and oxidative stress. Practical applications : This study screened the optimal formula for preparing microencapsulated deer oil powder and proved for the first time that deer oil powder has a strong gastroprotective effect on ethanol-induced acute gastric injury in rats. The gastric protective mechanism of deer oil powder is mainly to reduce oxidative stress, inflammatory cytokine accumulation and to increase the content of defense factors. Therefore, deer oil powder can be used as a new source of gastric treatment drugs. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Synthetic Route of C21H44O5).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Synthetic Route of C21H44O5

Characterization of the composition of plant protection products in different formulation types employing suspect screening and unknown approaches was written by Hergueta-Castillo, Maria Elena;Lopez-Ruiz, Rosalia;Garrido Frenich, Antonia;Romero-Gonzalez, Roberto. And the article was included in Journal of the Science of Food and Agriculture in 2022.Safety of Glyceryl monostearate The following contents are mentioned in the article:

Plant protection products (PPPs) are used extensively in agriculture to control crops. These PPPs, which may be found in different types of formulations, are composed of a designated pesticide (active principle) and other inactive ingredients as co-formulants. They perform specific functions in the formulation, as solvents, preservatives or antifreeze agents, among others. A research technique based on ultra-high-performance liquid chromatog. (UHPLC) coupled to a Quadrupole-Orbitrap mass analyzer was successfully applied to characterize the composition of six different PPPs in terms of the presence of co-formulants and types of formulations: emulsifiable concentrate (EC), emulsion in water (EW), suspension concentrate and water-dispersible granule. These PPPs (FLINT MAX, MASSOCUR 12.5 EC, IMPACT EVO, TOPAS, LATINO and IMPALA STAR) had antifungal activity, containing one triazole compound as active principle (tebuconazole, penconazole, myclobutanil, flutriafol or fenbuconazole, resp.). Non-targeted approaches, applying suspect and unknown anal., were carried out and ten compounds were identified as potential co-formulants. Six (glyceryl monostearate, 1-monopalmitin, DMSO, N,N-dimethyldecanamide, hexaethylene glycol and 1,2-benzisothiazol-3(2H)-one) were confirmed by injecting anal. standards Finally, these compounds were quantified in the PPPs. The current study allowed for detecting co-formulants in a wide range of concentrations, between 0.04 (DMSO) and 19.00 g L-1 (glyceryl monostearate), highlighting the feasibility of the proposed anal. methodol. Moreover, notable differences among the types of formulations of PPPs were achieved, revealing that EC and EW were the formulations that contained the largest number of co-formulants (four out of six detected compounds). 2022 The Authors.

Design and Comparative Evaluation of Vancomycin HCl-Loaded Rosin-Based In Situ Forming Gel and Microparticles was written by Chuenbarn, Tiraniti;Sirirak, Jitnapa;Tuntarawongsa, Sarun;Okonogi, Siriporn;Phaechamud, Thawatchai. And the article was included in Gels in 2022.Name: Glyceryl monostearate The following contents are mentioned in the article:

Vancomycin hydrochloride (HCl) is a glycopeptide antibiotic used to treat serious or life-threatening infections, and it reduces plaque scores and gingivitis in periodontal patients. In this study, vancomycin HCl was incorporated into rosin in situ forming gel (ISG) and rosin in situ forming microparticles (ISM) to generate a local drug delivery system to treat periodontal disease. The phys. properties of the ISG and ISM were measured, including pH, viscosity, injectability, adhesion properties, in-vitro transformation, and drug release. Moreover, the effectiveness of antimicrobial activity was tested using the agar-cup diffusion method against Staphylococcus aureus, Streptococcus mutans, Porphyromonas gingivalis, and Escherichia coli. Vancomycin HCl-loaded rosin-based ISG and ISM had a pH value in the range of 5.02-6.48 and exhibited the ease of injection with an injection force of less than 20 N. Addnl., the lubricity effect of the external oil phase of ISM promoted less work of injection than ISG and 40-60% rosin-based ISM showed good emulsion stability. The droplet size of emulsions containing 40%, 50%, and 60% rosin was 98.48 卤 16.11, 125.55 卤 4.75, and 137.80 卤 16.8渭m, resp. Their obtained microparticles were significantly smaller in diameter, 78.63 卤 12.97, 93.81 卤 10.53, and 118.32 卤 15.61渭m, resp., because the particles shrank due to the solvent loss from solvent exchange. Moreover, increasing the concentration of rosin increased the size of microparticles. After phase transformation, all formulations had better plasticity properties than elasticity; therefore, they could easily adapt to the specific shape of a patient’s gum cavity. Both developed ISG and ISM presented inhibition zones against S. mutans and P. gingivalis, with ISG presenting significantly more effectively against these two microbes (p < 0.05). The vancomycin HCl-loaded rosin ISG and ISM delayed drug release for 7 days with efficient antimicrobial activities; thus, they exhibit potential as the drug delivery systems for periodontitis treatment. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Name: Glyceryl monostearate).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Name: Glyceryl monostearate

Stress response to oxytetracycline and microplastic-polyethylene in wheat (Triticum aestivum L.) during seed germination and seedling growth stages was written by Bao, Yanyu;Pan, Chengrong;Li, Dezheng;Guo, Aiyun;Dai, Fengbin. And the article was included in Science of the Total Environment in 2022.Computed Properties of C21H44O5 The following contents are mentioned in the article:

Much efforts have been devoted to clarify the phytotoxicity of individual contaminants in plants, such as individual antibiotic and microplastic; however, little is known about the phytotoxicity of their combined exposure. Here, we investigated the effects of individual and combined exposure of wheat (Triticum aestivum L.) (Xiaoyan 22) to oxytetracycline (OTC) and polyethylene (PE) microplastics using physiol. and metabolic profilings. During the seed germination stage, OTC induced phytotoxicity, as observed through the changes of root elongation, sprout length, fresh weight and the vitality index, with significant effect at the 50 and 150 mg路L-1 levels; the effect of PE microplastics depended on the OTC level in the combined exposure groups. During seedling cultivation, catalase (CAT) and ascorbate peroxidase (APX), as antioxidant enzyme indexes, were sensitive to OTC exposure stress, although OTC was not determined in leaves. Untargeted metabolomics of wheat leaves revealed OTC concentration-, metabolite class- and PE-dependent metabolic responses. Dominant metabolites included carboxylic acids, alcs., and amines in the control group and all treatment groups. Compared to only OTC treatment, PE reprogrammed carboxylic acid and alc. profiles in combined exposure groups with obvious separation in PLS-DA. Combined exposure induced fewer metabolites than OTC exposure alone at the 5 and 50 mg路L-1 levels. The shared metabolite numbers were higher in the OTC groups than in the PE-OTC groups. Pathway enrichment anal. showed a drift in metabolic pathways between individual and combined exposure to OTC and PE, which included glyoxylate and dicarboxylate metabolism, amino acid metabolism and isoquinoline alkaloid biosynthesis. Among metabolites, aromatic acids and amino acids were more sensitive to combined exposure than individual exposure. These results contribute to clarifying the underlying mechanisms of phytotoxicity of individual and combined exposure to OTC and PE.

A package of established analytical tools to investigate the solid-state alteration of lipid-based excipients was written by Salar-Behzadi, Sharareh;Corzo, Carolina;Laggner, Peter. And the article was included in Journal of Visualized Experiments in 2022.Safety of Glyceryl monostearate The following contents are mentioned in the article:

Lipid-based excipients (LBEs) are low-toxic, biocompatible, and natural-based, and their application supports the sustainability of pharmaceutical manufacturing However, the major challenge is their unstable solid-state, affecting the stability of the pharmaceutical product. Critical phys. properties of lipids for their processing-such as melt temperature and viscosity, rheol., etc.-are related to their mol. structure and their crystallinity. Additives, as well as thermal and mech. stress involved in the manufacturing process, affect the solid-state of lipids and thus the performance of pharmaceutical products thereof. Therefore, understanding the alteration in the solid-state is crucial. In this work, the combination of powder x-ray diffraction and differential scanning calorimetry (DSC) is introduced as the gold standard for the characterization of lipids’ solid state. X-ray diffraction is the most efficient method to screen polymorphism and crystal growth. The polymorphic arrangement and the lamella length are characterized in the wide- and small-angle regions of x-ray diffraction, resp. The small-angle x-ray scattering (SAXS) region can be further used to investigate crystal growth. Phase transition and separation can be indicated. DSC is used to screen the thermal behavior of lipids, estimate the miscibility of additives and/or active pharmaceutical ingredients (API) in the lipid matrix, and provide phase diagrams. Four case studies are presented in which LBEs are either used as a coating material or as an encapsulation matrix to provide lipid-coated multiparticulate systems and lipid nanosuspensions, resp. The lipid solid-state and its potential alteration during storage are investigated and correlated to the alteration in the API release. Qual. microscopical methods such as polarized light microscopy and SEM are complementary tools to investigate micro-level crystallization Further anal. methods should be added based on the selected manufacturing process. The structure-function-processability relationship should be understood carefully to design robust and stable lipid-based pharmaceutical products. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Safety of Glyceryl monostearate).

It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Safety of Glyceryl monostearate

Digestion of lipid excipients and lipid-based nanocarriers by pancreatic lipase and pancreatin was written by Zoeller, Katrin;To, Dennis;Knoll, Patrick;Bernkop-Schnuerch, Andreas. And the article was included in European Journal of Pharmaceutics and Biopharmaceutics in 2022.Reference of 31566-31-1 The following contents are mentioned in the article:

The digestion behavior of lipid-based nanocarriers (LNC) has a great impact on their oral drug delivery properties. In this study, various excipients including surfactants, glycerides and waxes, as well as various drug-delivery systems, namely self-emulsifying drug delivery systems (SEDDS), solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) were examined via the pH-stat lipolysis model. Lipolysis experiments with lipase and pancreatin revealed the highest release of fatty acids for medium chain glycerides, followed by long chain glycerides and surfactants. Waxes appeared to be poor substrates with a maximum digestion of up to 10% within 60 min. Within the group of surfactants, the enzymic cleavage decreased in the following order: glycerol monostearate > polyoxyethylene (20) sorbitan monostearate > PEG-35 castor oil > sorbitan monostearate. After digestion experiments of the excipients, SEDDS, SLN and NLC with sizes between 30 and 300 nm were prepared The size of almost all formulations was increasing during lipolysis and levelled off after approx. 15 min except for the SLN and NLC consisting of cetyl palmitate. SEDDS exceeded 6000 nm after some minutes and were almost completely hydrolyzed by pancreatin. No significant difference was observed between comparable SLN and NLC but surfactant choice and selection of the lipid component had an impact on digestion. SLN and NLC with cetyl palmitate were only digested by 5% whereas particles with glyceryl distearate were decomposed by 40-80% within 60 min. Addnl., the digestion of the same SLN or NLC, only differing in the surfactant, was higher for SLN/NLC containing polyoxyethylene (20) sorbitan monostearate than PEG-35 castor oil. This observation might be explained by the higher PEG content of PEG-35 castor oil causing a more pronounced steric hindrance for the access of lipase. Generally, digestion experiments performed with pancreatin resulted in a higher digestion compared to lipase. According to these results, the digestion behavior of LNC depends on both, the type of nanocarrier and on the excipients used for them. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Reference of 31566-31-1).

Effects of oven and foam mat drying on proximate, functional, and reconstitution characteristics of instant powders from selected legumes was written by Falade, Kolawole O.;Adedeji, Alice O.. And the article was included in Journal of Food Processing and Preservation in 2022.Application In Synthesis of Glyceryl monostearate The following contents are mentioned in the article:

The effects of oven and foam mat drying on proximate, functional, and reconstitution characteristics of instant powders from selected legumes were investigated. Cotyledons of the legumes were sep. cooked and oven-dried, and sep. cooked and foamed, using glyceryl monostearate and egg albumin, and oven-dried. Foam d. of pastes incorporated with egg albumin or glyceryl monostearate (3-6 min) varied with whipping time and legume. Dry matter, protein, ash, crude fiber, fat and carbohydrate contents of oven- and foam-mat-dried legume powders varied from 92.75-98.75, 20.05-51.68, 0.96-1.07, 0.60-3.87, 1.36-4.13, and 43.63-71.85 g/100 g. Loose and packed bulk densities ranged from 0.48-0.63 to 0.68-0.9 g/mL, while WAC and OAC varied from 3.01-3.99 to 2.04-2.67 g/g, resp. Dispersability, wettability, solubility, and swelling index varied from 6.33-216.00, 6.33-216.00, 6.67-46.01 s, and 2.54-6.67 g/g, resp. The oven- and foam-mat-dried powders could provide the basis for preparation of acceptable instant soups from the selected legumes. Legumes are cheap and good source of essential protein and other nutrients with great nutritional benefits. However, legumes have minimal utilization due to associated prolonged and difficulty of cooking, and low palatability. Moreover, the processing of legumes into soups is laborious, time-consuming, and energy intensive, particularly when the product is needed to be produced frequently. Conversion of underutilized legumes to instant soup-based powders to which other ingredients could be added for the preparation of soups has huge potentials. This will allow for the preparation of soups with different variety, taste, and consistency based on consumers preference. Therefore, processing of underutilized legumes into instant soup-base powders which could be reconstituted and prepared present an innovative way of improving legume utilization and alleviate associated challenges. Dehydration of cooked legume cotyledon or pastes into instant powder would further enhance the shelf stability and reconstitution of the instant soup-base powders. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Application In Synthesis of Glyceryl monostearate).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application In Synthesis of Glyceryl monostearate

Raloxifene-loaded solid lipid nanoparticles decorated gel with enhanced treatment potential of osteoporosis was written by Guo, Zhonghua;Qi, Ping;Pei, Donghong;Zhang, Xiuju. And the article was included in Journal of Drug Delivery Science and Technology in 2022.Formula: C21H44O5 The following contents are mentioned in the article:

Osteoporosis is a common metabolic disorder associated with global morbidities and mortalities which make it a big challenge to the public health. Despite the availability of a number of drugs, its treatment is challenging due the drugs associated complications including poor dissolution, abridged permeation, reduced bioavailability and severe toxicities. This study aims to develop Raloxifene HCl-loaded solid lipid nanoparticles (RAL-SLNs) decorated gel in order to address the above-mentioned problems. RAL-SLNs were prepared by high pressure homogenization and evaluated in terms of their size distribution, morphol., zeta potential and drug entrapment using DLS anal., TEM and HPLC. Prior to this, screening of the lipid and surfactant was done based on drug solubility ratio. The optimized SLNs were further incorporated in chitosan gel to develop RAL-SLNs decorated gel (RAL-SLNsG) and were characterized in terms of their rheol. properties, pH and spreadability. In vitro drug release, kinetics of drug release and permeation analyses of the RAL-SLNsG were performed and compared with drug suspension and RAL gel (conventional gel) to check the release and permeation ability of the incorporated dug. Moreover, pharmacokinetics study of the test formulations was performed to check the bioavailability. Addnl., biochem. estimation was done after inducing osteoporosis in rats and their treatment with RAL-SLNsG and RAL gel after transdermal administration and were compared with pos. and neg. control groups. RAL-SLNs were found to have rounded shaped size distribution of 170 nm with -24.5 mV zeta potential and 95% drug entrapment. The RAL-SLNsG has excellent spreadability, optimum and non-Newtonian flow behavior. In vitro release and ex vivo permeation showed 7-fold and 11-fold enhanced properties, as compared to RAL suspension, resp. Bioavailability study revealed 3-fold and 6-fold enhanced bioavailability of the drug when incorporated in SLNs decorated gel as compared to the conventional gel and drug suspension. Finally, the serum level of alk. phosphatase and calcium were found to be significantly reduced in osteoporosis induced rats after treatment with RAL-SLNsG decorated gel as compared to RAL gel. These finding revealed that nanogel has the potential to enhance the permeation and bioavailability of incorporated drug with enhanced anti-osteoporotic effect. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Formula: C21H44O5).

Multiple sclerosis (MS), a multifactorial autoimmune disease of the central nervous system (CNS), is characterized by demyelination and chronic inflammation, as well as axonal and neuronal loss. There is no cure for MS, and despite a significant improvement in the therapeutic management of patients during the last 20 years, some symptoms are still resistant to treatment, and the evolution of the disease to progressive form seems still ineluctable. The etiol. of MS is complex and still not fully understood. However, inflammation is a major driver of physiopathol. and oxidative stress contributes to CNS lesions and promotes existing inflammatory response. Plant polyphenols are endowed with many therapeutic benefits through alleviating oxidative stress and inflammation, thus providing neuroprotection in MS. We presently evaluated the curative effect of grape seed extract (GSE) in an exptl. autoimmune encephalomyelitis (EAE) mouse model of MS. Exptl. approach: Six-week-old C57Bl/6J females were subjected to the EAE paradigm (using myelin oligodendrocyte glycoprotein peptide fragment (35-55), complete Freund鈥瞫 adjuvant, and pertussis toxin) and then chronically treated with GSE from day 10 to day 30 post-induction. Clin. score and body weight were monitored daily, while evaluation of sensitive, motor, cognitive, and anxiety-related behaviors was performed weekly. Then, the GSE effect was evaluated on whole brain and spinal cord samples through the evaluation of oxidative stress damage, antioxidant capacities, myelin alteration, astroglial and microglial proliferation, and sirtuin expression. Grape seed extract curative chronic treatment corrected the clin. course of EAE, as well as the mech. hypersensitivity, and avoided the development of EAE mouse thermal cold allodynia. The neuropathol. evaluation showed that GSE reduced oxidative stress in the brain and spinal cord by decreasing the lipid and protein oxidation through correction of the three main antioxidant enzyme activities, namely, superoxide dismutase, catalase, and glutathione peroxidase, as well as restoring normal myelin protein expression and correcting microglial and astroglial protein overexpression and sirtuin downregulation. These data strongly support GSE as an effective therapeutic approach in MS treatment.
