And the article was included in Journal of Photochemistry and Photobiology, A: Chemistry in 2011.Quality Control of 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

In an effort to develop water-soluble singlet-oxygen (¹O₂) photosensitizer, we synthesized a series of phosphorus porphyrin complexes (1, (RO)₂P(tpp)⁺Cl^–, tpp = tetraphenylporphyrinato ligand, R = -(CH₂CH₂O)_m-(CH₂)_n-H, m = 0-3, n = 1, 2, 4, 6) and evaluated their performance characteristics. Water-solubilities of 1 (m = 1, 2 and n = 1, 2, 4, 6) were determined to be >1.0 mM, which was higher than the parent (HO)₂P(tpp)⁺Cl^–. The quantum yields for the generation of ¹O₂ in water based on the amount of ¹ 1* were determined to be 0.73, 0.69, and 0.62 for 1d (m = 2, n = 4), 1e (m = 2, n = 2), and 1f (m = 2, n = 1), resp. Photo-inactivation by 1 was performed with yeast (Saccharomyces cerevisiae), and was evaluated using a inactivation factor A _F = ([1]_M × T _1/2)^-1, where [1]_M is the min. effective concentration of 1 and T _1/2 is a half-life of the yeast initially used. In the case of 1b (m = 1, n = 6) and 1c (m = 2, n = 6), [1]_M was determined to be 5 nM in the photo-sterilization. Bio-affinity was evaluated by the adsorbed concentration of 1 ([P]_ad) into the yeast, which was measured by absorption spectrophotometry using a confocal laser-scanning microscope. These findings revealed that a large amount of 1 was adsorbed into the yeast. The estimated amount of 1b obtained from 10 μM aqueous solution came to 171 mM (17,100 fold) in terms of concentration As an increase in carbon number (n) of the alkyl group on axial ligands, A _F and [P]_ad increased. It is strongly suggested that the photo-inactivation took place with the assistance of the attack of ¹O₂ inside the cells. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Quality Control of 2-(2-(Hexyloxy)ethoxy)ethanol).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics.

Osteoinductive activity of bisdemethoxycurcumin and its synergistic protective effect with human amniotic mesenchymal stem cells against ovariectomy-induced osteoporosis mouse model was written by Wei, Jin-Xing;Luo, Yi;Xu, Yan;Xiao, Jian-Hui. And the article was included in Biomedicine & Pharmacotherapy in 2022.Related Products of 33171-05-0 The following contents are mentioned in the article:

Osteoporosis is a common disease characterized by skeletal fragility and microarchitectural deterioration. However, existing conventional drugs exhibit limited efficacy and can elicit severe adverse effects; moreover, and novel stem cell-based therapies have not exhibited sufficient therapeutic efficacy. Our hypothesis is that an appropriate osteogenic inducer may improve their therapeutic efficacy. In this study, we found that bisdemethoxycurcumin (BDMC) stimulates the differentiation of human amniotic mesenchymal stem cells (hAMSCs) into osteoblasts without inducing cytotoxicity. Here BDMC enhances calcium deposition in hAMSCs, while promoting the expression of early and late markers of osteoblast differentiation, including ALP, runt-related transcription factor 2, osterix, COL1-α1, osteocalcin, and osteopontin at the transcriptional and translational levels. Mechanistically, BDMC was found to activate the JAK2/STAT3 pathway; whereas AG490 (JAK2/STAT3 pathway inhibitor) inhibited BDMC functioning. Subsequently, we found that the combinatorial therapy of BDMC and hAMSC had a pos. synergistic effect on osteoporotic mouse model induced by bilateral ovariectomy, including inhibiting bone loss and bone resorption and improving bone micro-architecture. Moreover, BDMC inhibited production of the bone resorption markers C-terminal telopeptide of type I collagen, and tartrate resistant acid phosphatase, while promoting serum levels of bone formation markers OCN, and procollagen I N-terminal propeptide. BDMC also improved liver and kidney function in osteoporotic mouse model. Collectively, BDMC improved osteoporosis by enhancing hAMSC osteogenesis and exhibited a protective effect on liver and kidney function in an osteoporotic mouse model. Hence, BDMC may serve as an effective adjuvant, and combined therapy with hAMSCs is a promising new approach toward osteoporosis treatment. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Related Products of 33171-05-0).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. 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.Related Products of 33171-05-0

Antimicrobial Properties of Corn Stover Lignin Fractions Derived from Catalytic Transfer Hydrogenolysis in Supercritical Ethanol with a Ru/C Catalyst was written by Kalinoski, Ryan M.;Li, Wenqi;Mobley, Justin K.;Asare, Shardrack O.;Dorrani, Masoumeh;Lynn, Bert C.;Chen, Xiaowen;Shi, Jian. And the article was included in ACS Sustainable Chemistry & Engineering in 2020.Application In Synthesis of 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

Converting lignin to value added products at high yields provides an avenue for making ethanol biorefineries more profitable while reducing the carbon footprint of products generally derived from petroleum. In this study, corn stover lignin was depolymerized by catalytic transfer hydrogenolysis (CTH) in supercritical ethanol with a Ru/C catalyst. The lignin derived bio-oil was then sequentially extracted utilizing hexane, petroleum ether, chloroform and Et acetate as solvents in order of less polar to polar and the subsequent bio-oils were characterized using GPC, GC/MS and HSQC NMR. Results show lignin derived compounds were sequentially extracted into groups depending on the solvent polarity. Antimicrobial properties of the bio-oils were screened against Gram-pos. (Bacillus subtilis, Lactobacillus amylovorus, and Staphylococcus epidermidis), Gram-neg. (Escherichia coli) bacteria and yeast (Saccharomyces cerevisiae) by examining microbial growth inhibition. Results show that CTH derived bio-oils inhibited all tested organisms at concentrations less than 3 mg/mL. Total monomer concentration and the presence of specific monomers (i.e., syringyl propane) showed correlations to antimicrobial activity, likely due to cell death or membrane damage. This study provides insights into using sequential extraction to fractionate lignin-derived compounds and correlations between the properties of the extracted compounds and their antimicrobial activity. A lignin-based bio-oil was prepared from catalytic transfer hydrogenolysis of purified corn stover lignin with ethanol and a ruthenium on carbon catalyst. Polar and nonpolar solvents were used to sequentially extract different compounds The raw bio-oil and sequential extraction fractions exhibited antimicrobial properties against Gram-pos./neg. bacteria and yeast, with activity related to total monomer content and specific monomers.

Metabolomics reveals diet-derived plant polyphenols accumulate in physiological bone was written by Alldritt, Isabelle;Whitham-Agut, Beatrice;Sipin, Miguel;Studholme, Jacob;Trentacoste, Angela;Tripp, Jennifer A.;Cappai, Maria Grazia;Ditchfield, Peter;Deviese, Thibaut;Hedges, Robert E. M.;McCullagh, James S. O.. And the article was included in Scientific Reports in 2019.SDS of cas: 2380-78-1 The following contents are mentioned in the article:

Plant-derived secondary metabolites consumed in the diet, especially polyphenolic compounds, are known to have a range of pos. health effects. They are present in circulation after ingestion and absorption and can be sequestered into cells within particular organs, but have rarely been investigated systematically in osteol. tissues. However, a small number of polyphenols and similar mols. are known to bind to bone. For example alizarin, a plant derived anthraquinone and tetracycline (a naturally occurring antibiotic), are both absorbed into bone from circulation during bone formation and are used to monitor mineralization in osteol. studies. Both mols. have also been identified serendipitously in archaeol. human bones derived from natural sources in the diet. Whether an analogus mechanism of sequestration extends to addnl. diet-derived plant-polyphenols has not previously been systematically studied. We investigated whether a range of diet-derived polyphenol-like compounds bind to bone using untargeted metabolomics applied to the anal. of bone extracts from pigs fed an acorn-based diet. We analyzed the diet which was rich in ellagitannins, extracts from the pig bones and surrounding tissue, post-mortem. We found direct evidence of multiple polyphenolic compounds in these extracts and matched them to the diet. We also showed that these compounds were present in the bone but not surrounding tissues. We also provide data showing that a range of polyphenolic compounds bind to hydroxyapatite in vitro. The evidence for polyphenol sequestration into physiol. bone, and the range and specificity of polyphenols in human and animal diets, raises intriguing questions about potential effects on bone formation and bone health. Further studies are needed to determine the stability of the sequestered mols. post-mortem but there is also potential for (palaeo)dietary reconstruction and forensic applications. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1SDS of cas: 2380-78-1).

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

Effect of Molecular Structure on Wetting Behavior at the Air-Liquid Interface of Water + Alcohol Mixtures was written by Yeh, Ming-Chih;Lin, Ping-Chang;Chen, Li-Jen. And the article was included in Journal of Physical Chemistry B in 2004.Synthetic Route of C10H22O3 The following contents are mentioned in the article:

In this study, the wetting behavior of binary water + alc. mixtures was carefully investigated by using eight different short-chain alcs. These binary mixtures exhibit liquid-liquid equilibrium over the exptl. temperature range 10∼40 °C. The wetting behavior of the upper liquid (alc.-rich) phase at the surface of the lower liquid (aqueous) phase can be determined according to the wetting coefficient resulting from the interfacial tension measurements. Mol. structure of alcs. plays an essential role in the wetting behavior. The purpose of this study is threefold. (1) The effect of the hydrocarbon chain length of alcs. was examined by employing water + 1-butanol (C₄E₀), water + 1-pentanol (C₅E₀), and water + 1-hexanol (C₆E₀) three systems, where C_iE_j is the abbreviation of a nonionic polyoxyethylene alc. C_iH_2i+1(OCH₂CH₂)_jOH. The shorter chain alc. has a stronger tendency to wet the surface of the aqueous phase. (2) The effect of number of oxyethylene groups of alcs. was investigated by using three mixtures, water + C₆E₀, water + C₆E₁, and water + C₆E₂. An interfacial phase transition from partial wetting to nonwetting was observed for water + C₆E_j mixtures as the number of oxyethylene groups j increases from 1 to 2. (3) The effect of isomeric structures of alcs. on wetting behavior was investigated by studying three mixtures, water + 1-pentanol, water + 2-pentanol (2-C₅E₀), and water + tert-pentanol (t-C₅E₀). An interfacial phase transition from partial wetting to complete wetting occurs while the mol. structure of alcs. evolves from linear (C₅E₀) to near spherical (t-C₅E₀) shape. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Synthetic Route of C10H22O3).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. 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.Synthetic Route of C10H22O3

Black pepper prevents anemia of inflammation by inhibiting hepcidin over-expression through BMP6-SMAD1/ IL6-STAT3 signaling pathway was written by Banerjee, Somesh;Katiyar, Parul;Kumar, Lokesh;Kumar, Vijay;Saini, Shashank Sagar;Krishnan, Vengadesan;Sircar, Debabrata;Roy, Partha. And the article was included in Free Radical Biology & Medicine in 2021.Electric Literature of C9H12O3 The following contents are mentioned in the article:

Hepcidin, a circulatory hepatic peptide hormone, is associated with systemic iron homeostasis. Inflammation leads to an increase in hepcidin expression, which dysregulates body iron level. The related disorder, anemia of inflammation, is the second most prevalent anemia-related disorder worldwide. In the present study, we conducted in vitro and in vivo studies to evaluate the effect of black pepper (BP) and its major bioactive alkaloid, piperine, on anemia of inflammation. The initial in vitro study using human hepatocyte cell line, HepG2, confirmed that among different black pepper extracts: methanol (BPME), ethanol (BPEE) and aqueous (BPAE), BPME to be most effective in downregulating transcription of hepcidin gene. Further, BPME and piperine significantly downregulated hepcidin protein expression at 200μg/mL and 100μM concentrations, resp. In the next phase, BPME and piperine were found to significantly attenuate BMP-6 and IL-6 induced hepcidin overexpression by downregulating the increased level of pSMAD1 and pSTAT3 proteins, resp. For in vivo study, we first s.c. injected male BALB/c mice with oil of turpentine, thrice within a period of two weeks, in order to enhance the expression of hepcidin. After that, the i.p. administration of BPME and piperine at 70 and 25 mg/kg body weight, resp., on alternate days for a period of another two weeks resulted in downregulation of hepcidin overexpression in diseased mice, as confirmed by RT-PCR and immunoblot anal. The histopathol. of liver tissue confirmed increased iron bioavailability in BPME and piperine treated animals. The mol. docking-based interaction studies demonstrated the binding potential of piperine with SMAD1 and STAT3 proteins. The binding patterns supported the proposed inhibition of hepcidin activating proteins. All together, these findings suggest black pepper as a therapeutic candidate for the treatment of anemia of inflammation. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Electric Literature of C9H12O3).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. 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. 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.Electric Literature of C9H12O3

Repigmentation by combined narrow-band ultraviolet B/adipose-derived stem cell transplantation in the mouse model: role of Nrf2/HO-1-mediated Ca²⁺ homeostasis was written by Bian, Yuanyuan;Yu, Hao;Jin, Mingzhu;Gao, Xinghua. And the article was included in Molecular Medicine Reports in 2022.Reference of 103-16-2 The following contents are mentioned in the article:

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.

Identification of phenolic compounds in Australian grown dragon fruits by LC-ESI-QTOF-MS/MS and determination of their antioxidant potential was written by Chen, Zhicong;Zhong, Biming;Barrow, Colin J.;Dunshea, Frank R.;Suleria, Hafiz A. R.. And the article was included in Arabian Journal of Chemistry in 2021.Recommanded Product: 33171-05-0 The following contents are mentioned in the article:

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.
