Imada, Motosuke published the artcileCopolymers incorporated with β-substituted acrylate synthesized by organo-catalyzed group-transfer polymerization, Application of Methyl 3-phenyl-2-propenoate, the publication is Polymer Journal (Tokyo, Japan) (2021), 53(9), 989-999, database is CAplus.

Various copolymers incorporated with β-substituted acrylates, such as alkyl crotonates (e.g., Me crotonate (MC), Et crotonate (EC), iso-Pr crotonate (iPC), and Bu crotonate (nBC)) and Me cinnamate (MCin), were synthesized by group-transfer polymerization (GTP) using a silicon-based Lewis acid catalyst. In addition to β-substituted acrylates, α-substituted acrylates (e.g., Me methacrylate (MMA) and Bu methacrylate (nBMA)) were examined as comonomers. Proton NMR (¹H NMR) spectroscopy and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) characterizations of the obtained copolymers revealed that each monomer component was incorporated sufficiently. The thermal stabilities of the resulting copolymers were investigated by dynamic mech. anal. (DMA), indicating that the glass-transition temperature (T_g) of the copolymers can be widely varied over a relatively high-temperature range by selecting the optimal comonomer. More specifically, the T_g values of poly(MC-random-EC) (MC/EC molar ratio = 50/50), poly(MC-random-nBC) (MC/nBC molar ratio = 50/50), poly(MC-random-MCin) (MC/MCin molar ratio = 54/46), and poly(nBC-random-MCin) (nBC/MCin molar ratio = 56/44) were 173, 130, 216, and 167°C, resp.

Wang, Jing published the artcileCharacterization of the Volatile Compounds in Camellia oleifera Seed Oil from Different Geographic Origins, SDS of cas: 103-26-4, the publication is Molecules (2022), 27(1), 308, database is CAplus and MEDLINE.

Volatile flavor of edible oils is an important quality index and factor affecting consumer choice. The purpose of this investigation was to characterize virgin Camellia oleifera seed oil (VCO) samples from different locations in southern China in terms of their volatile compounds to show the classification of VCO with respect to geog. Different samples from 20 producing VCO regions were collected in 2020 growing season, at almost the same maturity stage, and processed under the same conditions. Headspace solid-phase microextraction (HS-SPME) with a gas chromatog.-mass spectrometer system (GC-MS) was used to analyze volatile compounds A total of 348 volatiles were characterized, including aldehydes, ketones, alcs., acids, esters, alkenes, alkanes, furans, phenols, and benzene; the relative contents ranged from 7.80-58.68%, 1.73-12.52%, 2.91-37.07%, 2.73-46.50%, 0.99-12.01%, 0.40-14.95%, 0.00-27.23%, 0.00-3.75%, 0.00-7.34%, and 0.00-1.55%, resp. The VCO geog. origins with the largest number of volatile compounds was Xixiangtang of Guangxi (L17), and the least was Beireng of Hainan (L19). A total of 23 common and 98 unique volatile compounds were detected that reflected the basic and characteristic flavor of VCO, resp. After PCA, heatmap and PLS-DA anal., Longchuan of Guangdong (L8), Qingshanhu of Jiangxi (L16), and Panlong of Yunnan (L20) were in one group where the annual average temperatures are relatively low, where annual rainfalls are also low. Guangning of Guangdong (L6), Yunan of Guangdong (L7), Xingning of Guangdong (L9), Tianhe of Guangdong (L10), Xuwen of Guangdong (L11), and Xiuying of Hainan (L18) were in another group where the annual average temperatures are relatively high, and the altitudes are low. Hence, volatile compound distributions confirmed the differences among the VCO samples from these geog. areas, and the provenance difference evaluation can be carried out by flavor.

Mahmoud, Engy published the artcileDetermination of volatiles, antioxidant activity, and polyphenol content in the postharvest waste of Ocimum basilicum L, SDS of cas: 103-26-4, the publication is Food Chemistry (2022), 131692, database is CAplus and MEDLINE.

The treatment of postharvest wastes is an integral part of the food value chain. Therefore, Ocimum basilicum L. residues were dried in an oven and a microwave. Volatiles were extracted using hydrodistillation, headspace solid-phase microextraction (HS-SPME) and then analyzed by Gas Chromatog.-Mass Spectrometry (GC-MS). Thirty volatiles were identified in raw material, with β-linalool, methyleugenol, methylcinnamate, and estragole predominating. Meanwhile, 24 and 18 volatiles were detected in the oven- and microwave-dried samples, with a significant decrease of methyleugenol content. The highest radical scavenging ability and total phenolic content were achieved for microwaved wastes using photochemiluminescence, DPPH, and Folin-Ciocalteu test. Moreover, 8 phenolic acids and 9 flavonoids were identified in the LC-MS/MS anal., with significant contents of rosmarinic acid and luteolin (1042.45 and 11.68μg/g of dry matter, resp.) in the microwaved basil. This experiment pointed out that microwaved basil wastes could be re-used in the food, pharmacy and/or cosmetic industries.

Schlumpberger, Philipp published the artcileDevelopment and evaluation of an automated solvent-assisted flavor evaporation (aSAFE), Recommanded Product: Methyl 3-phenyl-2-propenoate, the publication is European Food Research and Technology, database is CAplus.

Artifact-avoiding isolation of the volatiles from foods is a crucial step before anal. of odor-active compounds by gas chromatog. (GC). In the past 20 years, solvent extraction followed by solvent-assisted flavor evaporation (SAFE) has become the standard approach, particularly prior to GC-olfactometry. The manual valve of the SAFE equipment, however, leads to suboptimal yields and the risk of a contamination of the volatile isolate with non-volatiles. We thus developed an automated SAFE (aSAFE) approach by replacing the manual valve with an electronically controlled pneumatic valve. The aSAFE provides clearly higher yields than the manual SAFE (mSAFE), notably from extracts high in lipids and for odorants with comparably high b.ps. Addnl., aSAFE substantially reduces the risk of non-volatiles being transferred to the volatile isolate. Full automatisation is possible by combining the aSAFE approach with an automated liquid nitrogen refill system as well as an endpoint recognition and shut-off system.

Xu, Jin-Di published the artcileMild Copper-Catalyzed Addition of Arylboronic Esters to Di- tert -butyl Dicarbonate: An Easy Access to Methyl Arylcarboxylates, Synthetic Route of 103-26-4, the publication is Synlett (2021), 32(8), 833-837, database is CAplus.

An efficient copper-catalyzed addition of arylboronic esters to (Boc)₂O was developed. The reaction can be conducted under exceedingly mild conditions and was compatible with a variety of synthetically relevant functional groups. It therefore represents a useful alternative route for the synthesis of Me arylcarboxylates. A preliminary mechanistic study indicated the involvement of an addition-elimination mechanism.

Aungtikun, Jirapon published the artcileImproved adulticidal activity against Aedes aegypti (L.) and Aedes albopictus (Skuse) from synergy between Cinnamomum spp. essential oils, Application In Synthesis of 103-26-4, the publication is Scientific Reports (2021), 11(1), 4685, database is CAplus and MEDLINE.

Improved natural adulticidal agents against mosquito vectors are in urgent need, and essential oils from Cinnamomum plants can assume this role quite readily. Cinnamomum verum, C. cassia, and C. loureiroi essential oils (EOs) were extracted from the barks and evaluated for their chem. composition by GC-MS. The major constituent of the three EOs was cinnamaldehyde. WHO susceptibility tests on individual and combined EOs as well as cinnamaldehyde were conducted against female adults of Aedes aegypti and Aedes albopictus. All EO combinations exhibited a synergistic effect, manifesting a higher toxicity, with a synergistic value ranging from 2.9 to 6.7. Their increasing mortality value was improved between 16.0 to 41.7%. The highest synergistic effect was achieved by an EO combination of 0.5% C. cassia + 0.5% C. loureiroi, while the highest insecticidal activity was achieved by 2.5% C. verum + 2.5% C. cassia and 1% cinnamaldehyde, with a knockdown and mortality rate of 100% and a KT50 between 0.7 and 2.1 min. This combination was more toxic to both mosquito species than 1% w/v cypermethrin. These findings demonstrate that cinnamaldehyde and synergistic combinations of C. verum + C. cassia EOs and C. cassia + C. loureiroi EOs have a high insecticidal efficacy against Aedes populations.

Aquino, Fernanda Lima Torres de published the artciletrans-Cinnamic acid, but not p-coumaric acid or methyl cinnamate, induces fibroblast migration through PKA- and p38-MAPK signalling pathways., COA of Formula: C10H10O2, the publication is Journal of tissue viability (2021), 30(3), 363-371, database is MEDLINE.

AIM: Hydroxycinnamic acids their derivatives have various pharmacological properties. The hydroxycinnamic acid derivatives, methyl cinnamate, trans-cinnamic, and p-coumaric acids have been the object of study in the treatment of skin wounds. However, it is unclear whether these derivatives exert a direct beneficial effect on fibroblast function. In this study, we evaluated the effects of methyl cinnamate, trans-cinnamic, and p-coumaric acids on fibroblast migration in vitro. MATERIALS AND METHODS: NIH 3T3 and L929 fibroblast cell lines were exposed to each drug at several concentrations and the effect on cell viability, cell cycle, and extracellular matrix production were assessed by MTT assay, flow cytometry, and immunofluorescence staining, respectively. The effect on cell migration was examined using scratch assay. RESULTS: The results showed that hydroxycinnamic acid derivatives not affect cell viability, but increase fibroblast migration in the in vitro scratch-wound healing assay. They also induced an increase in S and G2/M phases accompanied by a decrease in the G0/G1 phase of the cell cycle. The cell proliferation inhibitor mitomycin C abolished the effect induced by p-coumaric acid and methyl cinnamate, indicating that only the trans-cinnamic acid stimulated migration. A transwell migration assay confirmed that trans-cinnamic acid-treated fibroblasts exhibited increased migration compared with untreated cells. trans-Cinnamic acid-induced fibroblast migration was decreased by PKA inhibitor and p38-MAPK inhibitor but not by JNK inhibitor. Additionally, trans-cinnamic acid-treated fibroblasts showed an increase in the production of laminin and collagen type I. CONCLUSION: Our study showed that trans-cinnamic acid improves fibroblast migration and modulates extracellular matrix synthesis, indicating its potential for accelerating the healing process.

Aminkhani, Ali published the artcileChemical Constituent, Antimicrobial Activity, and Synergistic Effect of the Stem, Leaf, and Flower Essential Oil of the Artemisia fragrans Willd. from Khoy, Quality Control of 103-26-4, the publication is Chemistry & Biodiversity (2021), 18(8), e2100241, database is CAplus and MEDLINE.

Artemisia fragrans is commonly used as a folk medicine as antispasmodic, anti-pyretic, anti-inflammatory, and abortifacient agents. The villagers use its pungent odor to repel rodents, mites, and pests, as well as its essential oil and smoke after burning to treat lung infections after uprooting the plant. Herein, we extracted the essential oils (EOs) of different parts of the plant and analyzed their chem. compositions and antibacterial activities. The chem. anal. led to the identification of 73, 59, and 57 compounds in the EOs of the stem, leaf, and flower, resp. All of the EOs exhibited antibacterial activities against both G+ and G- bacteria. The EOs of the leaf and flower were more effective against tested bacteria, except B. anthracis and P. aeruginosa, compared to that of the stem. The binary combination of the EOs (stem and flower) or (stem and leaf) showed a synergistic effect. Statistical anal. indicated EOs of leaf and flower are more potent than that of the stem. These findings suggest the application of leaf and flower of the plant, which not only can prevent its uprooting but also ensure better therapeutic function.
