Enzymatic hydrolysis of corn stover lignin by laccase, lignin peroxidase, and manganese peroxidase was written by Zhang, Sitong;Dong, Zijian;Shi, Jia;Yang, Chengrui;Fang, Yi;Chen, Guang;Chen, Huan;Tian, Chunjie. And the article was included in Bioresource Technology in 2022.Formula: C9H12O3 The following contents are mentioned in the article:

Lignin of high purity and structural integrity was isolated from the enzymic residue of corn stover. Degradation of the lignin by laccase, lignin peroxidase, and manganese peroxidase was investigated. Structural changes in the lignin after degradation were characterized by SEM, nitrogen adsorption and Fourier transform IR spectroscopy, and the enzymic products were systematically analyzed by gas chromatog. mass spectrometry. The highest percentage of lignin degradation was obtained with a mixture of three enzymes (25.79%): laccase (Lac), the starting enzyme of the mixed enzyme reaction, worked with lignin peroxidase (LiP), and manganese peroxidase (MnP) to further degrade lignin. This degradation destroyed the macromol. structure of lignin, broke its key chem. bonds, and opened benzene rings, thus producing more acidic compounds This study elucidated the concept of degrading lignin from corn stover using the Lac, LiP and MnP enzymes synergistically, thus providing a theor. basis for the biodegradation of lignin. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Formula: C9H12O3).

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. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Formula: C9H12O3

Ethanol/1,4-dioxane/formic acid as synergistic solvents for the conversion of lignin into high-value added phenolic monomers was written by Wu, Zhen;Zhao, Xinxu;Zhang, Jun;Li, Xun;Zhang, Yu;Wang, Fei. And the article was included in Bioresource Technology in 2019.Recommanded Product: 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

In this study, a mixture solvent of ethanol/1,4-dioxane/formic acid (FA) is firstly reported to efficaciously depolymerize industrial lignin to produce high-value added phenolic monomers, in which 1,4-dioxane acts as lignin solvent, ethanol acts as solvent, reactant and in situ hydrogen donor, and FA acts as acid catalyst and in situ hydrogen donor. The effects of solvent composition and reaction conditions on the lignin conversion and product yields were explored, resulting in a low residue yield of 6.57% and a high phenolic monomers yield of 22.4% at 300 °C for 2 h when Kraft lignin was depolymerized in the mixture solvent of ethanol/1,4-dioxane/FA (10:10:2, volume/volume). Moreover, possible reaction mechanism on lignin depolymerization in the mixture solvent was illustrated, suggesting a favorable synergistic effect among the three components of the mixture solvent. In addition, the satisfactory applicability of the mixture solvent was approved through the feedstock adaptability and recyclability experiments This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Recommanded Product: 4-Hydroxy-3-methoxyphenethanol).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) 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 contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

A New Family of Renewable Thermosets: Kraft Lignin Poly-adipates was written by Di Francesco, Davide;Rigo, Davide;Reddy Baddigam, Kiran;Mathew, Aji P.;Hedin, Niklas;Selva, Maurizio;Samec, Joseph S. M.. And the article was included in ChemSusChem in 2022.Application In Synthesis of 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

Thermosetting polymeric materials have advantageous properties and are therefore used in numerous applications. In this study, it was hypothesized and ultimately shown that thermosets could be derived from comparably sustainable sub-components. A two-step procedure to produce a thermoset comprising of Kraft lignin (KL) and the cross-linker adipic acid (AdA) was developed. The crosslinking was activated by means of an acetylating agent comprising isopropenyl acetate (IPA) to form a crosslinking mixture (CLM). The crosslinking was confirmed by FTIR and solid-state NMR spectroscopy, and the esterification reactions were further studied using model compounds When the KL lignin was mixed with the CLM, partial esterification occurred to yield a homogeneous viscous liquid that could easily be poured into a mold, as the first step in the procedure. Without any additions, the mold was heated and the material transformed into a thermoset by reaction of the two carboxylic acid-derivatives of AdA and KL in the second step. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Application In Synthesis of 4-Hydroxy-3-methoxyphenethanol).

One-pot bio-derived ionic liquid conversion followed by hydrogenolysis reaction for biomass valorization: A promising approach affecting the morphology and quality of lignin of switchgrass and poplar was written by Carrozza, Chiara Francesca;Papa, Gabriella;Citterio, Attilio;Sebastiano, Roberto;Simmons, Blake A.;Singh, Seema. And the article was included in Bioresource Technology in 2019.Application In Synthesis of 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

The use of bio-derived ionic liquids (e.g., cholinium lysinate) in a one-pot process was evaluated on overall sugar and lignin yields as a function of two model woody and herbaceous feedstocks, switchgrass and poplar, with emphasis on the study of phys. and chem. alterations in lignin structure, by performing a detailed mass balance anal. and chem. characterization. Multiple chromatog. and spectroscopic anal. techniques were applied tracking lignin reactivity and partitioning during the ionic liquid one-pot conversion. Depolymerization efficiency of the lignin-rich residue derived from the whole process was investigated as a function of different temperatures and pressures during catalytic hydrogenolysis by Ni(SO)₄. This study validates the potential of ionic liquid one pot process as an integrated approach for full exploitation of lignocellulosic feedstocks. The insights gained will contribute to the design of future conversion routes for efficient biomass deconstruction and lignin valorization.

Some constituents of the Mediterranean diet, such as extra-virgin olive oil (EVOO) contain substances such as hydroxytyrosol (HT) and its metabolite homovanillic alc. (HA). HT has aroused much interest due to its antioxidant activity as a radical scavenger, whereas only a few studies have been made on the HA mol. Both chem. synthesis and extraction techniques have been developed to obtain these mols., with each method having its advantages and drawbacks. In this study, we report the use of tyrosol from olive mill wastewaters as a starting mol. to synthesize HT and HA, using a sustainable procedure characterized by high efficiency and low cost. The effects of HT and HA were evaluated on two cell lines, THP-1 human leukemic monocytes and L-6 myoblasts from rat skeletal muscle, after treating the cells with a radical generator. Both HT and HA efficiently inhibited ROS production In particular, HT inhibited the proliferation of the THP-1 leukemic monocytes, while HA protected L-6 myoblasts from cytotoxicity.

Metal-Organic Framework-Mediated Synthesis of One-Dimensional Nitrogen-Doped Molybdenum Carbide for the Cleavage of Lignin and Dimeric Lignin Model Compounds was written by Wang, Qiuyue;Su, Tianmei;Wang, Yu;Chen, Yufang;Lu, Xinqing;Ma, Rui;Fu, Yanghe;Zhu, Weidong. And the article was included in ACS Sustainable Chemistry & Engineering in 2020.Synthetic Route of C9H12O3 The following contents are mentioned in the article:

Molybdenum carbide (Mo₂C) has emerged as a remarkable catalyst for the cleavage of the aromatic carbon-oxygen (C_aryl-O) and alkyl carbon-oxygen (C_alkyl-O) in lignin and lignin model compounds However, the selectivity for the target product, that is phenol, is unsatisfactory due to the secondary alkylation reactions of the primarily produced phenol with the organic solvent used. Here, we report that a one-dimensional nitrogen-doped Mo₂C catalyst (N-Mo₂C@C) mediated from Mo-MOF via a “pyrolysis-carbothermal reduction” process shows a remarkably high selectivity toward phenol and monophenols in the valorization of aryl ethers and lignin because of its controllable phase composition and suitable valence state. The current study provides a method to develop efficient catalysts for lignin conversion into valuable chems. Selective cleavage of the aromatic carbon-oxygen bonds in lignin and lignin dimers can be achieved over a MOF-derived one-dimensional nitrogen-doped molybdenum carbide.

And the article was included in Food Chemistry in 2022.Computed Properties of C9H12O3 The following contents are mentioned in the article:

The European Food Safety Authority highlights the beneficial effects of olive oil phenols, mainly, secoiridoids. Nevertheless, the metabolism of secoiridoids in humans has not been fully elucidated. This research evaluated the metabolism of secoiridoids in humans after intake of olive oils with diverse phenolic profiles. For this purpose, three extra virgin olive oils (EVOOs) were ingested by six volunteers at scheduled meals, and urine samples were collected the following morning for subsequent LC-MS/MS anal. Using untargeted anal., urinary metabolites revealed representative patterns associated with the various olive oil phenolic contents in absolute and relative terms. We were able to identify metabolites obtained through phase I, phase II, and microbial metabolism with discrimination between tyrosol and hydroxytyrosol derivatives Metabolism of phenols is differentially activated as a function of the olive oil secoiridoids content, and this proof-of-concept study shows how urinary metabolites represent olive oil phenolic content.

A nanoemulsion loaded with memantine for intranasal delivery to bypass the blood-brain barrier for the treatment of Alzheimer disease. The nanoemulsion was prepared using homogenisation and ultrasonication methods. The developed nanoemulsion was characterised, in vitro release and antioxidant potential was analyzed. The in vivo studies were carried out by radiolabelling the memantine with technetium pertechnetate. The finalised NE showed particle-size of ~11 nm and percentage transmittance of ~99%. The in vitro release studies showed 80% drug release in simulated nasal fluid. The nanoemulsion showed 98% cell viability and antioxidative assays confirmed that the encapsulation of memantine in a nanoemulsion sustained its antioxidative potential. Gamma images and biodistribution results also confirmed higher uptake of formulation with %radioactivity of 3.6 ± 0.18%/g at 1.5 h in brains of rats administered intranasally. The developed nanoemulsion could be used as a potential carrier of memantine for a direct nose to brain delivery.

Synthesis of sulfated oligosaccharide glycosides having high anti-HIV activity and the relationship between activity and chemical structure was written by Katsuraya, Kaname;Nakashima, Hideki;Yamamoto, Naoki;Uryu, Toshiyuki. And the article was included in Carbohydrate Research in 1999.SDS of cas: 112-59-4 The following contents are mentioned in the article:

Sulfated laminara-oligosaccharide glycosides having high anti-human immunodeficiency virus (HIV) activities were synthesized from laminara-tetraose, -pentaose and -hexaose. The oligosaccharide glycosides were synthesized by treating peracetylated β-oligosaccharides with various alcs. and Lewis acid catalysts. The effects of the number of glucose residues and the alkyl chain-length on anti-HIV activity were examined The anti-HIV activity of sulfated dodecyl laminara-pentaosides and -hexaosides increased with increasing degree of sulfation (DS) and the pentaoside having an almost fully-sulfated saccharide portion had the highest activity, whereas for the hexaoside a somewhat lower DS manifested the highest activity. Sulfated laminara-oligosaccharide glycosides having fluoroalkyl-containing aglycons of high hydrophobicity showed potent inhibitory effects against HIV infection. In contrast, hydrophilic substituents containing oligo(ethyleneoxy) groups as aglycons in the sulfated oligosaccharides did not show high anti-HIV activity. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4SDS of cas: 112-59-4).

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.SDS of cas: 112-59-4
