This study first evaluated the stimulatory effect of S. platensis biomass on the growth of L. acidophilus and the metabolic activity during fermentation (37 °C, 72 h) in a culture medium. The results demonstrated a higher impact of S. platensis biomass than fructooligosaccharide (FOS), an established prebiotic. Higher L. acidophilus proliferation rates and metabolic activity were observed (lower pH values and higher concentrations of acetic, lactic, and propionic acids) in the presence of S. platensis. Then, we evaluated the effects of the S. platensis biomass (1.5 g, twice a day, 5 days) in association with L. acidophilus (10⁶ CFU/g) on the gut microbiota composition of medium-age healthy individuals through the Simulator of Human Intestinal Microbial Ecosystem (SHIME) and measurement of metabolites. L. acidophilus (La5) and L. acidophilus + S. platensis (Spi-La5) could pos. modulate the intestinal microbiota. The administration of La5 resulted in increases in Bacteroides, Megasphaera, Lactobacillus, and Parabacteroides genus abundance, with a consequent decrease in ammonium ions. The administration of Spi-La5 increased the abundance of the genus Erysipelatoclostridium, Roseburia, Enterococcus, Bifidobacterium, Coriobacteriaceae UCG-003, Enterobacter, and Paraclostridium. The results demonstrate that the intestinal microbiota was differently modified by administrating La5 and Spi-La5 and indicate the latter as an alternative for microbiota pos. modulation in healthy individuals. This study involved multiple reactions and reactants, such as (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8COA of Formula: C30H26O12).

Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.COA of Formula: C30H26O12

Inhibition of Three Diabetes-Related Enzymes by Procyanidins from Lotus (Nelumbo nucifera Gaertn.) Seedpods was written by Xiang, Jie;Raka, Rifat Nowshin;Zhang, Luocheng;Xiao, Junsong;Wu, Hua;Ding, Zhiqian. And the article was included in Plant Foods for Human Nutrition in 2022.Computed Properties of C30H26O12 The following contents are mentioned in the article:

The inhibitory effects of procyanidins from lotus (Nelumbo nucifera Gaertn.) seedpods on the activities of α-amylase, α-glucosidase and protein tyrosine phosphatase 1B (PTP1B), were studied and compared with those of (+)-catechin, (-)-epicatechin, epigallocatechin gallate (EGCG), procyanidin dimer B2 and trimer C1. The results showed that Lotus procyanidin extract (LPE) significantly inhibited α-amylase, α-glucosidase and PTP1B with IC50 values of 5.5, 1.0, and 0.33μg/mL, resp. The inhibition increased with the d.p. and the existence of galloyl or gallocatechin units. Kinetic anal. showed that LPE inhibited α-glucosidase activity in a mixed competitive and noncompetitive mode. Fluorescence quenching revealed that α-glucosidase interacted with LPE or EGCG in an apparent static mode, or the model of “sphere of action”. The apparent static (K) and bimol. (kq) constants were 4375 M-1 and 4.375 x 1011 M-1 s-1, resp., for LPE and 1195 M-1 and 1.195 x 1011 M-1 s-1, resp., for EGCG. Mol. docking anal. provided further information on the interactions of (+)-catechin, (-)-epicatechin, EGCG, B2 and C1 with α-glucosidase. It is hypothesized that LPE may bind to multiple sites of the enzyme through hydrogen bonding and hydrophobic interactions, leading to conformational changes in the enzyme and thus inhibiting its activity. These findings first elucidate the inhibitory effect of LPE on diabetes-related enzymes and highlight the usefulness of LPE as a dietary supplement for the prophylaxis of diabetes. This study involved multiple reactions and reactants, such as (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8Computed Properties of C30H26O12).

Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Computed Properties of C30H26O12

Mechanistic insight into the one step green synthesis of hybrid rGO/Fe NPs was written by Wu, J.;Wu, P.;Weng, X.;Lin, J.;Owens, G.;Chen, Z.. And the article was included in Materials Today Nano in 2022.Electric Literature of C30H26O12 The following contents are mentioned in the article:

Recently, the green synthesis of iron nanoparticles and associated hybrids using plant extracts has attracted much attention due to its low cost, simplicity and environmental friendliness. However, the exact formation mechanism is still unclear. In this study, the one step green synthesis of hybrid rGO/Fe NPs by a tea extract was examined using a response surface methodol. (RSM) to obtain a high activity of rGO/Fe NPs. The results showed that the best conditions for synthesis were an extract concentration = 35 g/L, pH = 7, and temperature = 30°C. The optimized hybrid produced could remove 99.9% of mitoxantrone (MTX) compared to only 78.9% when unoptimized. To better understand the formation process, characterizations by SEM, TEM, AFM, FTIR, XRD, Raman, and XPS were performed. Theses characterizations showed that the Fe NPs produced had a particle size of 25 nm which were deposited randomly across the rGO nanosheet with a thickness of approx. 1.5 nm, indicating that stable hybrid rGO/Fe NPs were successfully synthesized, where the green tea extract exhibited both reducing and capping/stabilizing behavior. Furthermore, the specific biomols. in the green tea extract responsible for bio-reduction and stabilization were identified by GC-MS and LC-MS, which showed that catechins were the main reducing agents, while alkaloids, amino acids and phenolic acids were the main capping/stabilizing agents. Finally, a mechanism for synthesizing rGO/Fe NPs was proposed, where the polyphenols successfully reduced GO and complexed with iron ions to form amorphous ferric (and ferrous) polyphenol complex nanoparticles. This study involved multiple reactions and reactants, such as (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8Electric Literature of C30H26O12).

Molecular investigation of proanthocyanidin from Alpinia zerumbet against the influenza A virus was written by Morimoto, Hayato;Hatanaka, Tadashi;Narusaka, Mari;Narusaka, Yoshihiro. And the article was included in Fitoterapia in 2022.Category: alcohols-buliding-blocks The following contents are mentioned in the article:

Proanthocyanidins (PACs) have various bioactivities, such as being anti-bacterial, anti-cancer, and anti-oxidant. Consequently, they have been vigorously studied for the development of new natural bioactive compounds Recently, PAC was isolated from leaves and pseudostems of the medicinal plant Alpinia zerumbet (Pers.) B. L. Burtt and R. M. Smith, and it had shown in vitro antiviral activity against influenza A H1N1 viruses (IAVs). The 50% endpoint dilution method indicated that 0.1 mg/mL A. zerumbet-derived PAC (AzPAC) reduced the titer of IAVs by >3 logs. The antiviral activity of AzPAC means that it can interact directly with viral particles since the antiviral activity test was done by coincubation of PAC with and IAVs before viral infection. However, few studies have investigated the preventive mechanism utilized by AzPAC on influenza virus replication. In this study, the composition of AzPAC and the affinity between AzPAC and IAVs was investigated in detail. We found that AzPAC was composed of an epicatechin, which was linked by inter-flavan bonds between the C4 and C8 positions (B2-type) and the C4 and C6 positions (B5-type) in the terminal units. A quenching assay indicated that AzPAC interacted with IAV membrane proteins, hemagglutinin and neuraminidase. Addnl., CD anal. indicated that AzPAC affected the change in the secondary structure rate of the viral membrane proteins. AzPAC was able to impair the infective process of IAVs via direct interaction with their viral membrane proteins. These results indicate that A. zerumbet is a bioresource for the development of preventive drugs against IAV infection. This study involved multiple reactions and reactants, such as (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8Category: alcohols-buliding-blocks).

Ultrasonic-assisted extraction of polyphenolic compounds from Paederia scandens (Lour.) Merr. Using deep eutectic solvent: optimization, identification, and comparison with traditional methods was written by Liu, Yuxin;Zhe, Wang;Zhang, Ruifen;Peng, Ziting;Wang, Yuxi;Gao, Heqi;Guo, Zhiqiang;Xiao, Juan. And the article was included in Ultrasonics Sonochemistry in 2022.Application In Synthesis of (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol The following contents are mentioned in the article:

Ultrasonic-assisted extraction (UAE) coupled with deep eutectic solvent (DES) is a novel, efficient and green extraction method for phytochems. In this study, the effects of 16 DESs coupled with UAE on the extraction rate of polyphenols from Paederia scandens (Lour.) Merr. (P. scandens), an edible and medicinal herb, were investigated. DES synthesized with choline chloride and ethylene glycol at a 1:2 M ratio resulted in the highest extractability. Moreover, the effects of extraction parameters were investigated by using a two-level factorial experiment followed by response surface methodol. The optimal parameters (water content in DES of 49.2%, the actual ultrasonic power of 72.4 W, and ultrasonic time of 9.7 min) resulted in the optimal total flavonoid content (TFC) (27.04 mg CE/g DW), ferric-reducing antioxidant power (FRAP) value (373.27μmol Fe(II)E/g DW) and 2,2′-azino-bis(3-ethylbenzthiazoline)-6-sulfonic acid radical (ABTS+) value (48.64μmol TE/g DW), closely matching the exptl. results. Furthermore, a comparison study demonstrated that DES-UAE afforded the higher TFC and FRAP value than traditional extraction methods. 36 individual polyphenolic compounds were identified and quantified by ultra-high-performance liquid chromatog.-mass spectrometry (UHPLC-MS) in P. scandens extracts, and of which 30 were found in the extracts obtained by DES-UAE. Addnl., DES-UAE afforded the highest sum of individual polyphenolic compound content. These results revealed that DES-UAE enhanced the extraction efficiency for polyphenols and provided a scientific basis for further processing and utilization of P. scandens. This study involved multiple reactions and reactants, such as (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8Application In Synthesis of (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol).

The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Application In Synthesis of (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol

The soybean cultivar SCEL-1 shows potent anti-photoaging effects in a UV-induced three-dimensional human skin and hairless mouse model was written by Lee, Jin Woo;Peng, Lei;Jegal, Hyun;Park, No-June;Bong, Sim-Kyu;Lee, Joon Won;Pyo, Jeong Joo;Choi, Yongsoo;Kim, Su-Nam. And the article was included in Applied Biological Chemistry in 2022.Recommanded Product: (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol The following contents are mentioned in the article:

Soybean (Glycine max) is one of the major sources of nutrition and is used as a raw material for food and as a source of feed for livestock. The efficacy of soybeans on skin health includes their ability to reduce wrinkles and pigmentation and increase skin elasticity and moisture content. Black soybean has been consumed worldwide for a long time, especially in Korea, and is used as a medicinal food against several disorders related to the skin. To evaluate whether its effect on the skin is different based on the cultivar of soybeans, three black soybean cultivars collected in Korea, Soybean Core collection Elite Line-1 (SCEL-1), Chung Ja-3 (CJ-3) and Won Heuk (WH), were selected to compare their effect on improving photoaging induced by UV rays (UVs). We found that SCEL-1 exhibited the best efficacy among the three cultivars tested, and treatment with this soybean extract significantly reduced the expression of matrix metalloproteinase-1 (MMP-1), preventing the degradation of collagen in a 3D human skin model. In addition, SCEL-1 application improved wrinkle- and photoaging-related symptoms, such as epidermal thickening, collagen deficiency and immune cell infiltration, in an animal model established by UV irradiation Procyanidin B2 and epicatechin isolated from the SCEL-1 cultivar inhibited MMP-1 biosynthesis in UVB-irradiated human dermal fibroblasts, and these two major components are likely related to more significantly attenuated skin photoaging. Therefore, our results indicated that SCEL-1 exhibits good anti-wrinkle effects compared to the other two black soybean cultivars, suggesting that it represents an excellent agent for anti-photoaging. This study involved multiple reactions and reactants, such as (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8Recommanded Product: (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol).

A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Recommanded Product: (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol

The Ministry of AYUSH recommended the use of a decoction of the mixture of Ocimum tenuiflorum, Cinnamomum verum, Piper nigrum, Zingiber officinale, and Vitis vinifera as a preventive measure by boosting the immunity against the severity of infection caused by a novel coronavirus (COVID-19). The present study aimed to identify the probable modulated pathways by the combined action of AYUSH recommended herbal tea and golden milk formulation as an immune booster against COVID-19. Reported phytoconstituents of all the medicinal plants were retrieved from the ChEBI database, and their targets were predicted using DIGEP-Pred. STRING database and Cytoscape were used to predict the protein-protein interaction and construct the network, resp. Likewise, MolSoft and admet SAR2.0 were used to predict the druglikeness score and ADMET profile of phytoconstituents. The study identified the modulation of HIF-1, p53, PI3K-Akt, MAPK, cAMP, Ras, Wnt, NF-kappa B, IL-17, TNF, and cGMP-PKG signaling pathways to boost the immune system. Further, multiple pathways were also identified which are involved in the regulation of pathogenesis of the multiple infections and non-infectious diseases due to the lower immune system. Results indicated that the recommended herbal formulation not only modulated the pathways involved in boosting the immunity but also modulated the multiple pathways that are contributing to the progression of multiple disease pathogenesis which would add the beneficial effect in the co-morbid patients of hypertension and diabetes. The study provides the scientific documentation of the role of the Ayurvedic formulation to combat COVID-19.

Newly generated and increased bound phenolic in lychee pulp during heat-pump drying detected by UPLC – ESI-triple-TOF-MS / MS was written by Shu, Bin;Wang, Junmin;Wu, Guangxu;Cao, Xuejiao;Huang, Fei;Dong, Lihong;Zhang, Ruifen;Liu, Hesheng;Su, Dongxiao. And the article was included in Journal of the Science of Food and Agriculture in 2022.Product Details of 29106-49-8 The following contents are mentioned in the article:

During the thermal processing of fruit, it has been observed for phenolic compounds to either degrade, polymerize, or transfer into macromols. In this study, the bound and free phenolic compound composition, content, and phenolic-related enzyme activity of lychee pulp were investigated to determine whether the free phenolic had converted to bound phenolic during heat-pump drying (HPD). It was found that after HPD, when compared with the fresh lychee pulp (control), the content of bound phenolics of dried lychee pulp had increased by 62.69%, whereas the content of free phenolics of dried lychee pulp decreased by 22.26%. It was also found that the antioxidant activity of bound phenolics had also increased after drying. With the use of high-performance liquid chromatog.-tandem mass spectrometry, it was identified that (+)-gallocatechin, protocatechuic aldehyde, isorhamnetin-3-O-rutoside, 3,4-dihydroxybenzeneacetic acid, and 4-hydroxybenzoic acid were newly generated during HPD, when compared with the control sample. After drying, the contents of gallic acid, catechin, 4-hydroxybenzoic acid, vanillin, syringic acid, and quercetin in bound phenolics had also increased, and polyphenol oxidase and peroxidase still showed enzyme activity, which could be related to the conversion of free phenolics to bound phenolics. Overall, during the thermal processing of lychee pulp, the free phenolics weres found to be converted into bound phenolics, new substances were generated, and antioxidant activity was increased. Hence, it was concluded that HPD improved the bound phenolics content of lychee pulp, thus providing theor. support for the lychee processing industry. 2021 Society of Chem. Industry.

Antioxidant and apoptotic activity of cocoa bean husk extract on prostate cancer cells was written by Choi, Jinhee;Yang, Changwon;Lim, Whasun;Song, Gwonhwa;Choi, Haeyeon. And the article was included in Molecular & Cellular Toxicology in 2022.Safety of (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol The following contents are mentioned in the article:

Although prostate cancer is the most commonly diagnosed cancer in men, its incidence among Asians, who consume foods rich in phenols, is relatively low compared with that in other populations. Cocoa bean husk (CBH) is an important byproduct of the cocoa industry; its polyphenol content (catechin, epicatechin, and procyanidin B) is as high as that of cocoa beans. However, there are no studies on the anticancer effect of CBH. Herein, we assessed the antioxidant and anticancer effects of CBH on prostate cancer cells. We fractionated CBH ethanol crude extract and compared the total polyphenol content, total flavonoid content, and DPPH and ABTS+ radical scavenging activities of the fractions. Catechin, epicatechin, and procyanidin B were analyzed by HPLC in the Et acetate (EAF) and butanol (BF) fractions, which had the highest physiol. content and antioxidant activity. PC3 and DU145 cells were treated with the two fractions, and annexin V/propidium iodide, and TUNEL assays were performed to assess apoptosis and DNA fragmentation, resp. The highest phytochem. content and antioxidant activity were observed in EAF, followed by those in BF. HPLC anal. revealed high content of phenolic compounds in both these fractions. Notably, catechin (5.64 mg/g), epicatechin (20.47 mg/g), and procyanidin B (20.29 mg/g) were abundant in EAF. Both fractions induced apoptosis in a concentration-dependent manner in PC3 and DU145 cells, and DNA fragmentation at a concentration of 200 μg/mL. CBH, a byproduct of cocoa processing, contains large amounts of phenolic compounds and exhibits high antioxidant activity and anticancer effects on prostate cancer cells. CBH has potential applications as a functional food material.

Vaccinium vitis-idaea L. (lingonberry) leaves and fruits have traditionally been used in Asian and European countries as a natural solution for urinary tract infections, gastrointestinal distress, neurodegenerative diseases, and related inflammatory disorders, which are overall associated with free radical damage and presence of triggering pathogenic strains in the human body. Considering growing attention to natural products, there are not enough scientific data to confirm predominant specialized metabolites, responsible for the traditional therapeutic use of lingonberries. The present study aimed at an in-depth study of specialized metabolite profiling and biol. activity evaluation of lingonberry crude extracts and isolated fractions. Crude dry extracts and fractions from lingonberry leaves and fruits were analyzed by the UPLC-MS method. Potential inhibiting properties against different bacterial strains and hyaluronidase, ability to scavenge hydrogen peroxide, and effect on its production in a macrophage culture J774 were examined Findings suggested the tentative presence of 59 compounds, mainly phenolics, displayed higher bioactivities of particular fractions than that of crude extracts and elucidated particular compounds as candidates in pharmaceuticals. Trimeric and dimeric proanthocyanidins from lingonberry leaves and fruits were shown to have the strongest antimicrobial, antioxidant, and anti-inflammatory potential. This study revealed specialized metabolites responsible for the traditional medicinal properties of lingonberries and pointed out demand for further purification and new research directions of proanthocyanidins in the frame of their multipharmacol. perspectives. This study involved multiple reactions and reactants, such as (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8Formula: C30H26O12).

(2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Formula: C30H26O12
