Thorough lignin characterization is vital to understand the physicochem. properties of lignin and to evaluate lignocellulose biorefinery processes. In this study, an in-depth characterization of lignin oil, obtained from reductive catalytic fractionation (RCF) of pine wood, was performed with quant. GC x GC – FID anal. and qual. GC x GC – MS. By utilizing high-temperature resistant column sets in the GC x GC system and by applying a derivatization step, unambiguous detection of lignin monomers, dimers, and trimers is enabled. In addition to confirm the identity of eleven monomers, corresponding to 34 wt% of the RCF lignin oil, thirty-six dimers (16 wt%) and twenty-one trimers (7 wt%) were comprehensively identified by anal. of their mass spectra and quantified by a FID, encompassing the identity of an addnl. 23 wt% of the RCF lignin oil. The proposed structures reveal the interlinkages present in the dimeric and trimeric oligomers, containing β-5, β-1, β-β, 5-5, and a minor fraction of β-O-4 and 4-O-5 bonds. Furthermore, aliphatic end-units in the dimeric and trimeric mols. were identified, consisting of various substituents at the C4 position, that have been previously observed in the RCF-derived lignin monomers. To reduce complexity for anal., the RCF oil was separated into six fractions, prior to anal. The structural motifs (inter-unit linkages and end-units) that are found in the different fractions vary significantly, such that the lignin fractions extracted in more polar solvents contained higher mol. weight fragments and more hydroxyl containing structural motifs. The identified structures of individual dimer and trimer mols. by GC x GC align well with and further complement the recent findings from ¹H-¹³C HSQC NMR spectroscopy, demonstrating complementarity between both 2D techniques to obtain a holistic view on both the mol. structures and the distribution of bonds and end-units in RCF oil. The combination of these two techniques provides a powerful tool for future RCF and other lignin depolymerization research. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Quality Control of 4-Hydroxy-3-methoxyphenethanol).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. 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. 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.Quality Control of 4-Hydroxy-3-methoxyphenethanol

Lead (Pb) exposure induces physiological alterations in the serotoninergic and vasopressin systems causing anxiogenic-like behavior in Meriones shawi: Assessment of BDMC as a neuroprotective compound for Pb-neurotoxicity and kidney damages was written by Tamegart, Lahcen;Abbaoui, Abdellatif;El khiat, Abdelaati;Bouyatas, Moulay Mustapha;Gamrani, Halima. And the article was included in Journal of Trace Elements in Medicine and Biology in 2021.HPLC of Formula: 33171-05-0 The following contents are mentioned in the article:

Studies have shown that lead (Pb) is one of hazardous heavy metals with various adverse effects on human health including mental health; Pb can induce psychiatric disorders like anxiety. In the present work, we examined the potential of bisdemethoxycurcumin (BDMC) as a neuroprotective agent against lead induced anxiety in Meriones shawi (M. shawi). We asses, the potential of three consecutive day exposure to Pb (25 mg/kg body weight) in inducing anxiogenic effect, serotoninergic and vasopressinergic disruptions in M. shawi. This was done using neurobehavioral tests (open field, elevated plus maze), immunohistochemestry by anti-serotonin (5-HT), and anti-vasopressin (AVP) antibodies. We also measured the possible restorative potential of BDMC (30 mg/kg body weight), delivered by oral gavage. After that, a biochem. and histopathol. studies were done. Our results showed that lead exposure for three consecutive days increases significantly the 5-HT-immunoreactivity in dorsal raphe nucleus (DRN) accompanied with a significant enhancement of AVP-immunoreactivity in the cell bodies and fibers in the supraoptic (SON) and paraventricular (PVN) nuclei of the hypothalamus. In the collecting tube, AVP binds to the V2 receptor of the epithelial cells and increases the water permeability. Our results showed clearly the epithelial cells degeneration after lead exposure, then we suggest that the increased AVP could be a response to the hydric balance disrupted after degenerative effect of lead exposure on epithelial cells. BDMC produced an anxiolytic effect in meriones. Moreover, it restored 5-HT and AVP immunoreactivity within studying nuclei. The biochem. and histopathol. studies showed that Pb induced renal damages. In addition, BDMC restored the renal alterations. According to the obtained results, we suggest new pharmacol. effects of BDMC; while it has an anxiolytic effect against Pb-induced anxiety by working on serotoninergic and vasopressinergic systems with an obvious restoration of the renal injuries induced by lead exposure. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0HPLC of Formula: 33171-05-0).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. 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.HPLC of Formula: 33171-05-0

Insights into the electrochemical degradation of phenolic lignin model compounds in a protic ionic liquid-water system was written by Liu, Guangyong;Wang, Qian;Yan, Dongxia;Zhang, Yaqin;Wang, Chenlu;Liang, Shijing;Jiang, Lilong;He, Hongyan. And the article was included in Green Chemistry in 2021.Recommanded Product: 4-Benzyloxyphenol The following contents are mentioned in the article:

Cleavage of aryl ether (Caryl-O) bonds is crucial for the conversion and value-added utilization of lignin and its derivatives, but remains extremely challenging under mild conditions due to strong Caryl-O linkages. In this study, the Caryl-O bond breaking is achieved through electrocatalytic oxidation of four phenolic lignin model compounds with typical Caryl-O bonds, i.e., 4-ethoxyphenol (EP), 4-phenoxyphenol (PP), p-benzyloxyphenol (PBP), and 2-(2-phenylethoxy)phenol (2-PEP), in a protic ionic liquid [BSO₃Hmim][OTf]-H₂O electrolyte, and the electrocatalytic oxidation mechanism is also fully explored. The effects of H₂O on the viscosity and conductivity of the [BSO₃Hmim][OTf] ionic liquid system, as well as the solubility and diffusion coefficients of O₂ and the four lignin substrates, are investigated to optimize the optimal ratio of the electrolyte system composed of [BSO₃Hmim][OTf] and H₂O. Electrochem. oxidation-reduction behaviors of the four lignin substrates in the [BSO₃Hmim][OTf]-H₂O system and the effect of O₂ and N₂ atmospheres on degradation are studied in detail by using cyclic voltammetry (CV) curves. Finally, by combining the anal. of degradation products with isotope labeling experiments, the C-O bond cleavage mechanism is obtained, which mainly involves direct and indirect oxidation Specifically, under a N₂ atmosphere, the substrates are oxidized directly on the RuO₂-IrO₂/Ti mesh electrode through Caryl-O bond splitting to form quinone and carbonium ions, while under an O₂ atmosphere, apart from the direct oxidation on the electrode, indirect oxidation of the lignin substrates also occurs through in situ generated H₂O₂. This study may provide some insight into developing effective strategies for efficient utilization of lignin under mild conditions. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Recommanded Product: 4-Benzyloxyphenol).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are also usually derived from carboxylic acids. 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. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: 4-Benzyloxyphenol

Curcumin (CM), demethoxycurcumin (DMC), and bisdemethoxycurcumin (BDMC) are major curcumin derivatives found in the rhizome of turmeric (Curcuma longa L.), and have yielded impressive properties to halt various diseases. In the present study, we carried out a method validation for curcumin derivatives and analyzed the contents simultaneously using HPLC with UV detection. For validation, HPLC was used to estimate linearity, range, specificity, accuracy, precision, limit of detection (LOD), and limit of quantification (LOQ). The results showed a high linearity of the calibration curve, with a coefficient of correlation (R2) for CM, DMC, and BDMC of 0.9999, 0.9999, and 0.9997, resp. The LOD values for CM, DMC, and BDMC were 1.16, 1.03, and 2.53 ng/μL and LOQ values were 3.50, 3.11, and 7.67 ng/μL, resp. Moreover, to evaluate the ability of curcumin derivatives to reduce liver lipogenesis and compare curcumin derivatives′ therapeutic effects, a HepG2 cell model was established to analyze their hepatoprotective properties. Regarding the in vivo study, we investigated the effect of DMC, CM, and BDMC on nonalcoholic fatty liver disease (NAFLD) caused by a methionine choline deficient (MCD)-diet in the C57BL/6J mice model. From the in vitro and in vivo results, curcumin derivatives alleviated MCD-diet-induced lipid accumulation as well as high triglyceride (TG) and total cholesterol (TC) levels, and the protein and gene expression of the transcription factors related to liver adipogenesis were suppressed. Furthermore, in MCD-diet mice, curcumin derivatives suppressed the upregulation of toll-like receptors (TLRs) and the production of pro-inflammatory cytokines. In conclusion, our findings indicated that all of the three curcuminoids exerted a hepatoprotective effect in the HepG2 cell model and the MCD-diet-induced NAFLD model, suggesting a potential for curcuminoids derived from turmeric as novel therapeutic agents for NAFLD. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Application of 33171-05-0).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water.

Spice-rich recipes are referred to as “functional foods” because they include a variety of bioactive chems. that have health-promoting properties, in addition to their nutritional value. Using pharmacoinformatics-based anal., we explored the relevance of bioactive chems. found in Rasam (a South Indian cuisine) against oxidative stress-induced human malignancies. The Rasam is composed of twelve main ingredients, each of which contains a variety of bioactive chems. Sixty-six bioactive compounds were found from these ingredients, and their structures were downloaded from Pubchem. To find the right target via graph theor. anal. (mitogen-activated protein kinase 6 (MAPK6)) and decipher their signaling route, a network was built. Sixty-six bioactive compounds were used for in silico mol. docking study against MAPK6 and compared with known MAPK6 inhibitor drug (PD-173955). The top four compounds were chosen for further study based on their docking scores and binding energies. In silico anal. predicted ADMET and physicochem. properties of the selected compounds and were used to assess their drug-likeness. Mol. dynamics (MD) simulation modeling methodol. was also used to analyze the effectiveness and safety profile of selected bioactive chems. based on the docking score, as well as to assess the stability of the MAPK6-ligand complex. Surprisingly, the discovered docking scores against MAPK6 revealed that the selected bioactive chems. exhibit varying binding ability ranges between – 3.5 and – 10.6 kcal mol-1. MD simulation validated the stability of four chems. at the MAPK6 binding pockets, including Assafoetidinol A (ASA), Naringin (NAR), Rutin (RUT), and Tomatine (TOM). According to the results obtained, fifty of the sixty-six compounds showed higher binding energy (- 6.1 to – 10.6 kcal mol-1), and four of these compounds may be used as lead compounds to protect cells against oxidative stress-induced human malignancies.

Dragon fruit is a popular tropical fruit that has a high phenolic content which are the main contributors to the antioxidant potential and health benefits of dragon fruit pulp and peel waste. Although some phenolic compounds in dragon fruit have previously been reported, a comprehensive anal. of complete phenolic profile of the Australian varieties has not been conducted. Thus, the aim of this study was to extract, identify and quantify phenolics from dragon fruits grown in Australia. Phenolic compounds were extracted from the peels and pulps of white and red dragon fruit. Phenolic content was determined by total phenolic content (TPC), total flavonoid content (TFC) and total tannin content (TTC), while antioxidant activities were measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), 2,2′-Azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and total antioxidant capacity (TAC). The results showed that dragon fruit pulp had a higher total phenolic content and stronger antioxidant capacity than peel, while the peel had a higher content of flavonoids and tannins than the pulp. Liquid chromatog. electrospray ionization quadrupole time-of-flight mass spectrometry (LC-ESI-QTOF-MS/MS) was used for the characterization of phenolic compounds, a total of 80 phenolics including phenolic acids (25), flavonoids (38), lignans (6), stilbene (3) and other polyphenols (8) were characterized in all dragon fruits. High performance liquid chromatog. equipped with photodiode array detector (HPLC-PDA) quantified the phenolic compounds in different portion of dragon fruit and showed that dragon peel had higher concentrations of phenolics than pulp. The results highlighted that both dragon fruit peel and pulp are potential sources of phenolic compounds, with peel in particular being a source of antioxidant phenolics with potential as ingredients for the food and pharmaceutical industries.

Vitiligo is a depigmentation disease commonly seen in clin. practice, mainly involving loss of functional epidermal pigment cells and hair follicle melanocytes. Narrow-band UV B (NB-UVB) has emerged as the first choice of treatment for vitiligo, but long-term exposure may have serious consequences. Recently, it was reported that adipose-derived stem cells (ADSCs) improve melanocyte growth and the efficacy of melanocyte transplantation. The present study aimed to examine the efficacy of NB-UVB/ADSC-transplantation combined therapy on a mouse vitiligo model and explore the underlying mechanisms by focusing on endoplasmic reticulum stress and cellular calcium (Ca²⁺) homeostasis. Vitiligo mice models were established by applying 40% monobenzone (MBZ) cream twice daily and treated with NB-UVB/ADSC combination therapy. Some treated mice were also given ML385, a nuclear factor erythroid 2 like 2 (Nr2) inhibitor. Histopathol. changes were evaluated using a depigmentation evaluation score and observed with hematoxylin and eosin staining on skin tissues. ELISA was used to measure diagnostic markers in plasma. Flow cytometric assay was performed to quantify CD3⁺, CD4⁺ and CD8⁺ levels. Expression levels of associated proteins were detected with western blot and immunofluorescence. Treatment of mice with MBZ-induced depigmentation patches on the skin was accompanied with loss of redox balance and disruption of cellular Ca²⁺ homeostasis. Oxidative stress and Ca²⁺ unbalancing were improved after the mice were treated by NB-UVB/ADSCs transplantation combination therapy. ML385, strongly negated the protective effect of NB-UVB/ADSC transplantation combination therapy, indicating the critical role of Nr2 signaling. The findings improved the understanding of the pathogenesis of vitiligo and will guide future development of therapeutic strategies against it.
