Granulation tissue formation during skin wound healing requires the migration and proliferation of dermal libroblasts in the wound site, where a subsequent remodeling of extracellotar matrixes (ECM) occurs. An abnormality of ECM remodeling wilhin the healing wound leads to fibrosis and a contracted scar. To evaluate whether acteoside, a phenylethanoid glycoside isolated from the leaves of Rehmannia glutinosa LIBOSCH., exhibits wound-healing actions, we examined the effect of aeteoside on the expression of matrix metalloproteinases (MMPs) in normal human dermal fibroblasts (NHDF). Aeteoside dose- anti time-dependently augmented the activation of the precursor of MMP-2 (proMMP-2/progelatinase A) in untreated- and interleukin-1-treated NHDF, while the alteration of the MMP-2 gene expression was negligible. ′[he acteoside-induced proMMP-2 activation was associated with the augmented membrane-type I MMP (MT1-NIMP) expression in the NHDF. However, there was no change in the proMMP-2 activation in olher catechol derivatives: homovanillyl alc.- and homovanillie acid-treated NHDF, indicating that catechols in acteoside were requisite for the regulation of the IMP aclivalion and expression in NHDF. These results provide novel evidence that acteoside augments proMMP-2 activation along with an increase in MT1-MMP expression through a PI3K signal pathway in NHDF. Thus, acteoside is likely to be an attractive candidate that facilitates ECM remodeling in the skin wound repair process.

Olive Oil Phenols Prevent Mercury-Induced Phosphatidylserine Exposure and Morphological Changes in Human Erythrocytes Regardless of Their Different Scavenging Activity was written by Notariale, Rosaria;Perrone, Pasquale;Mele, Luigi;Lettieri, Gennaro;Piscopo, Marina;Manna, Caterina. And the article was included in International Journal of Molecular Sciences in 2022.Safety of 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

Phosphatidylserine (PS) translocation to the external membrane leaflet represents a key mechanism in the pathophysiol. of human erythrocytes (RBC) acting as an”eat me” signal for the removal of aged/stressed cells. Loss of physiol. membrane asymmetry, however, can lead to adverse effects on the cardiovascular system, activating a prothrombotic activity. The data presented indicate that structurally related olive oil phenols prevent cell alterations induced in intact human RBC exposed to HgCl₂ (5-40μM) or Ca²+ ionophore (5μM), as measured by hallmarks including PS exposure, reactive oxygen species generation, glutathione depletion and microvesicles formation. The protective effect is observed in a concentration range of 1-30μM, hydroxytyrosol being the most effective; its in vivo metabolite homovanillic alc. still retains the biol. activity of its dietary precursor. Significant protection is also exerted by tyrosol, in spite of its weak scavenging activity, indicating that addnl. mechanisms are involved in the protective effect. When RBC alterations are mediated by an increase in intracellular calcium, the protective effect is observed at higher concentrations, indicating that the selected phenols mainly act on Ca²+-independent mechanisms, identified as protection of glutathione depletion. Our findings strengthen the nutritional relevance of olive oil bioactive compounds in the claimed health-promoting effects of the Mediterranean Diet.

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. Polyesters are important plastics, with monomers linked by ester moieties. 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.

Compositional differences and similarities between typical chinese baijiu and western liquor as revealed by mass spectrometry-based metabolomics was written by Fang, Cheng;Du, Hai;Jia, Wei;Xu, Yan. And the article was included in Metabolites in 2019.Application In Synthesis of 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

Distilled liquors are important products, both culturally and economically. Chem., as a complex mixture, distilled liquor comprises various chem. compounds in addition to ethanol. However, the chem. components of distilled liquors are still insufficiently understood and compositional differences and similarities of distilled liquors from different cultures have never been compared. For the first time, both volatile organic compounds (VOCs) and non-VOCs in distilled liquors were profiled using mass spectrometry-based metabolomic approaches. A total of 879 VOCs and 268 non-VOCs were detected in 24 distilled liquors including six typical Chinese baijiu and 18 typical Western liquors. Principal component anal. and a correlation network revealed important insights into the compositional differences and similarities of the distilled liquors that were assessed. Et esters, a few benzene derivatives, and alcs. were shared by most distilled liquors assessed, suggesting their important contribution to the common flavor and mouthfeel of distilled liquors. Sugars and esters formed by fatty alc. differ significantly between the assessed Chinese baijiu and Western liquors, and are potential marker compounds that could be used for their discrimination. Factors contributing to the differences in chem. composition are proposed. Our results improve our understanding of the chem. components of distilled liquors, which may contribute to more rigorous quality control of alc. beverages.

Effect of Pyrolysis Temperature on the Characteristics of Wood Vinegar Derived from Chinese Fir Waste: A Comprehensive Study on Its Growth Regulation Performance and Mechanism was written by Lu, Xincheng;Jiang, Jianchun;He, Jing;Sun, Kang;Sun, Yunjuan. And the article was included in ACS Omega in 2019.Related Products of 2380-78-1 The following contents are mentioned in the article:

As a high value-added product from biomass pyrolysis, wood vinegar (WV) has been used as a growth regulator for many plant species in agriculture based on the diverse active chem. compounds present. To reveal the relationship between chem. constituents and regulation performance, four kinds of WVs were prepared by slow pyrolysis from Chinese fir waste at different temperature ranges. The chem. constituents of WVs were analyzed by gas chromatog.-mass spectrometry, and the regulation performance of WVs was investigated from the aspects of seed germination and root growth of wheat. The results indicated that the chem. constituents of WVs were affected obviously by pyrolysis temperature and the major components were acids and phenols. All types of WVs showed regulation performance but with different effects and levels. The WV collected from 20 to 150°C exhibited a promoting effect and other three WVs exhibited inhibiting effects. It was considered that the regulation performance of WV was relevant to acids and phenols through a synergy mechanism. Acids caused intercellular acidification and increased root activity, which promoted the seed germination and root growth, while phenols increased the content of malonaldehyde, indicating that phenols caused the oxidative stress to damage cell structure and inhibit growth. All these results could be a reference for further utilization of WVs as a sustainable alternative to chems. for plant growth regulation in agriculture.

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. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters.

Abstract: Purpose: Several studies have demonstrated the properties of hydroxytyrosol, a phenolic compound present in olive oils and olives with a well-characterized impact on human health. Nevertheless, some knowledge gaps remain on its bioavailability and metabolism; overall concerning to the real rate per cent of absorption and biovailability of dietary hydroxytyrosol and the influence of the dietary food-containing hydroxytyrosol on it. Methods: A double-blind study was performed including 20 volunteers who ingested 5 mg of hydroxytyrosol through diverse food matrixes, to discover the influence on pharmacokinetics and bioavailability of HT metabolites (hydroxytyrosol acetate, 3,4-dihydroxyphenylacetic acid (DOPAC), tyrosol, and homovanillic alc.) of the distinct matrixes by UHPLC-ESI-QqQ-MS/MS. Results: The HT pharmacokinetics after consumption of different food matrixes was strongly dependent on the food matrix. In this aspect, the intake of extra virgin olive exhibited significantly higher plasma concentrations after 30 min of oral intake (3.79 ng/mL) relative to the control. Regarding the hydroxytyrosol bioavailability, the intake of extra virgin olive oil, as well as fortified refined olive, flax, and grapeseed oils provided significantly higher urinary contents (0.86, 0.63, 0.55, and 0.33μg/mg creatinine, resp.) compared with basal urine, whereas hydroxytyrosol metabolites showed no significant changes. No differences were found between men and women. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Reference of 2380-78-1).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) 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, including apples, durians, pears, bananas, pineapples, and strawberries. 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.Reference of 2380-78-1

Comprehensive characterization of hydrothermal liquefaction products obtained from woody biomass under various alkali catalyst concentrations was written by Hwang, Hyewon;Lee, Jae Hoon;Choi, In-Gyu;Choi, Joon Weon. And the article was included in Environmental Technology in 2019.COA of Formula: C9H12O3 The following contents are mentioned in the article:

Hydrothermal liquefaction (HTL) of lignocellulosic biomass has been widely investigated for the production of renewable and alternative bio-crude oil. In this study, catalytic hydrothermal processing of two biomasses (larch and Mongolian oak) was performed using different K₂CO₃ concentrations (0, 0.1, 0.5, 1.0 wt% of solvent) to improve fuel yield and properties. HTL oil, hydrochar, water-soluble fraction (WSF) and gas were characterized, and carbon balance was investigated. As a result, the maximum yield of HTL oil, 27.7 wt% (Mongolian oak) and 25.7 wt% (larch), and the highest carbon conversion ratio was obtained with 0.5 wt% of catalyst. The high catalyst concentration also resulted in an increase in higher heating values up to 31.9 MJ/kg. In addition, the amount of organic compounds in HTL oil also increased, specifically for lignin-derived compounds including catechol and hydroquinone which can be derived from secondary hydrolysis of lignin. On the other hand, formation of hydrochar was suppressed with the addition of alkali catalyst and the yield dramatically decreased from 30.7-40.8 weight% to 20.0-21.8 weight%. Furthermore, it was revealed that WSF had low organic carbon content less than 3.4% and high potassium content mostly derived from alkali catalyst, indicating that it may be reusable with simple purification This work suggests that the addition of the proper amount of alkali catalyst can improve the production efficiency and quality of bio-crude oil, and another potential of WSF to be recyclable in further work.

Focus on Olea europaea L. pruning by-products: extraction techniques, biological activity, and phytochemical profile was written by Faraone, Immacolata;Russo, Daniela;Bruno, Maria Roberta;Todaro, Luigi;D′Auria, Maurizio;Milella, Luigi. And the article was included in Biofuels, Bioproducts & Biorefining in 2021.COA of Formula: C9H12O3 The following contents are mentioned in the article:

The Olea europaea L. tree has played a central role in Mediterranean culture since ancient times. Several studies have highlighted the health-promoting properties both of its primary products (olives) and its byproducts (leaves, pomace, husk, stone, mill wastes, and wood). In this study, pruning residues from 25-yr-old olive trees located in a Mediterranean region (Basilicata, Italy) were analyzed. The antioxidant activity of hydro-alc. extracts from wood samples were analyzed through three complementary in vitro assays. The mol. composition of the extracts was thoroughly evaluated using a gas chromatog. apparatus coupled with a mass spectrometer (GC-MS). Our study demonstrated that all but three extracts had remarkable antioxidant activity, which was likely due to the meaningful presence of phenolic compounds, mostly derived from lignin. Moreover, the results showed that bark extracts obtained with ultrasound-assisted extraction (UAE) had the highest antioxidant activity. In this extract, several known compounds with demonstrated antioxidant activity were found, including hexylresorcinol, 1-methyl-N-vanillyl-2-phenethamine, and allopurinol. This research suggests that woody olive byproducts are a potential natural resource of antioxidants. These compounds could be useful for functional foods and in industry, and could help to solve the problem of pruning residues, increasing their potential economic value. 2021 The Authors.

Improved hydrodeoxygenation of lignin-derived oxygenates and biomass pyrolysis oil into hydrocarbon fuels using titania-supported nickel phosphide catalysts was written by Insyani, Rizki;Choi, Jae-Wook;Yoo, Chun-Jae;Suh, Dong Jin;Lee, Hyunjoo;Kim, Kyeongsu;Kim, Chang Soo;Kim, Kwang Ho;Ha, Jeong-Myeong. And the article was included in Energy Conversion and Management in 2022.Synthetic Route of C9H12O3 The following contents are mentioned in the article:

Biomass pyrolysis oil is a potentially essential renewable energy source that can serve as an alternative to petroleum-based fuels and chems. In this study, biomass pyrolysis oil was converted into petroleum-like deoxygenated hydrocarbons via catalytic hydrodeoxygenation using a titania-supported nickel phosphide catalyst. The phosphor precursor was added to several transition metals, including nickel, cobalt, copper, and iron, supported on titania. The formation of isolated nickel phosphide particles, which were active for complete hydrodeoxygenation, was confirmed by the characterization of prepared catalysts. As a model reactant of biomass pyrolysis oil, a mixture of alkyl-methoxyphenol compounds was hydrodeoxygenated to produce completely deoxygenated compounds, generating an 87% yield of cycloalkanes at 300 °C and 4 MPa H2 for a reaction time of 2 h. The hydrodeoxygenation of biomass pyrolysis oil also generated a 37.4% yield of hydrocarbon fuels. The high hydrodeoxygenation activity can be attributed to the synergy between the hydrogenating metals and the acid sites, which can be improved by electron transfer from a slightly cationic nickel to a slightly anionic phosphor. Furthermore, the addition of phosphor improved the formation of highly dispersed nickel particles, increasing the quantity of hydrogen-adsorbing surface metals. The observations in this study indicate that the efficient conversion of lignocellulose-derivatives into chems. and fuels can be achieved using modified non-precious transition metal catalysts.

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.Synthetic Route of C9H12O3

Evaluation of a quasi-dimeric eugenol derivative as repellent against the stored grain insect pest Sitophilus oryzae ( Coleoptera Curculionidae ) was written by Abenaim, Linda;Mandoli, Alessandro;Venturi, Francesca;Bedini, Stefano;Conti, Barbara. And the article was included in Pest Management Science in 2022.Quality Control of 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

Essential oils (EOs) and their chem. components are often proposed as an alternative to synthetic pesticides for pest control of foodstuff insect pests. However, their low persistence and strong, spicy odor, make them poorly suitable for use to protect food. Modification of the EOs components mols. increases their mol. weight and reduce their volatility. However, the effectiveness of such modified mols. has, so far, not been tested against stored food insect pests. In this study, the intensity and the duration of the repellence against the insect pest Sitophilus oryzae of a recently synthesized quasi-dimeric eugenol derivative (ED) (C18H20O4) were compared to those of eugenol and three eugenol related compounds The hypothesis tested was that by its higher mol. weight and two functional groups the ED would overcome the low persistence and strong and spicy odor drawback of eugenol without compromising the repellence against insects. The insect behavioral tests showed a greater repellence and persistence of ED than eugenol and the three eugenol related compounds against S. oryzae. The sensory anal. of ED by panel test indicated that ED is significantly less odorous than eugenol without any spicy nor balsamic nuances in its smell profile. Because of its high repellence against insects and its low smell intensity for humans, ED could represent a valid repellent for the control of foodstuffs insect pests. 2022 The Authors.

Comparison of chemical composition of lipophilic extracts from Acacia mearnsii De Wild. wood of different ages was written by Oliveira, Gliciane Ramos Azevedo;Grasel, Fabio dos Santos;Paulino de Pinho, Gevany;Silverio, Flaviano Oliveira. And the article was included in Industrial Crops and Products in 2020.Synthetic Route of C9H12O3 The following contents are mentioned in the article:

Acacia mearnsii De Wild. has been cultivated in Brazil mainly for the extraction of tannins from bark, but its wood has been used to complement the demand for hardwood in the pulp and paper industries. However, few studies have been carried out aiming to characterize the chem. composition of the wood lipophilic extracts from this species. Some compounds of these extract may generate sticky deposits in machinery in the paper and pulp mills, known as pitch. In general, woods with a higher content of lipophilic extracts generate more problems and damage caused by pitch deposits. So, this paper details the chem. composition of the lipophilic extracts of A. mearnsii woods of four ages (4, 7, 10 and 13-yr-old) cultivated in Brazil. The wood from 7, 10 and 13-years-old trees showed similar amounts of lipophilic extracts ranging from 0.23 to 0.28%. However, the 4-yr-old wood presented more than twice that value i.e. 0.60%. These lipophilic extracts were analyzed by GC-MS before and after alk. hydrolysis, followed by derivatization. The main chem. classes found were fatty acids (27.1-95.0 mg kg-1), sterols (20.5-55.7 mg kg-1) and aromatic compounds (0.750-13.2 mg kg-1), followed by smaller amounts of long chain aliphatic alc. (0.00-3.46 mg kg-1) and hydrocarbons (0.00-2.62 mg kg-1), before and after hydrolysis. The results showed that the wood extracts from 7, 10 and 13-yr-old trees were similar from the quant. and qual. points of view, indicating that harvests over 7 years of age offer less propensity for pitch problems.

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) 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 C9H12O3
