Synthetic insecticides, a traditional tool to avoid the reduction of stored-product due to insects, have emerged a serious of hazards to the environment for years, therefore, botanicals have entered people’s vision. This work aimed to present the essential oil composition of Melaleuca bracteata, and the contact as well as repellent activities against three stored-product insects, i.e. Lasioderma serricorne (Coleoptera: Ptinidae), Tribolium castaneum (Coleoptera: Tenebrionidae), and Sitophilus oryzae (Coleoptera: Curculionidae). For determining the composition, the analysis was performed by GC/FID and GC/MS. Among 11 identified compounds, the principal compounds were methyl eugenol (88.52 %) and methyl cinnamate (7.90 %). The essential oil demonstrated contact toxicity against L. serricorne, T. castaneum, and S. oryzae which LD50 values were 3.2, 22.6, and 20.4 mu g/adult, respectively. Methyl cinnamate was more effective than methyl eugenol. The repellent activity indicated that essential oil and major compositions of M. bracteata were effective against L. serricorne and T. castaneum, but no use for S. oryzae. In the contact assay, L. serricorne showed more sensitivity, however, in repellency assay, T. castaneum was susceptible. We seek to provide a new application of the popular ornamental plant, M. bracteata, and offer an alternative material to botanical insecticides development.

Dan-Huang-Qu-Yu capsule, a Chinese herbal medicine compound preparation, is widely used for chronic pelvic inflammatory disease. In this study, a rapid, selective, and sensitive microwave-assisted extraction ultra-high-performance liquid chromatography-Q Exactive quadrupole-orbitrap high-resolution mass spectrometry method was developed for analyzing its chemical compositions. A total of 85 compounds, including 22 flavonoids, 8 terpenoids, 5 quinones, 5 phthaleolactone, 23 organic acids, and 22 other compounds were identified from Dan-Huang-Qu-Yu capsule. Among them, 35 major compounds were unambiguously detected by comparing them with reference standards and selected as quality control markers, which were simultaneously determined in Dan-Huang-Qu-Yu capsule. The established method was successfully validated and applied for simultaneous determination of 35 bioactive compounds in Dan-Huang-Qu-Yu capsule from ten sample batches. The quantitative data of the analytes were analyzed by principal component analysis for quality assessment of Dan-Huang-Qu-Yu capsule. Six compounds (e. g., astragaloside IV, salvianolic acid B, ellagic acid, chlorogenic acid, N-butylidenephthalide, and luteolin) were screened out and regarded as chemical markers for quality control of Dan-Huang-Qu-Yu capsule. The established method has been proved to be a novel and useful tool for rapid research of Dan-Huang-Qu-Yu capsule. This research will provide reference for the scientific research of traditional Chinese medicines.

Amides are ubiquitous molecules in nature and in synthetic chemistry. Here we report a convenient and efficient method to synthesize N-aryl amides via amidation of esters with nitroarenes. In the presence of manganese metal, this amidation proceeded smoothly without the need for additional catalysts or ligands. Various esters and nitroarenes are suitable substrates to afford a wide range of N-aryl amides, including bio-active molecules and intermediates to drug molecules.

p-Coumaric acid is a known inhibitor of tyrosinase, an enzyme involved in the initial steps of the melanin synthesis in human and other species. However, its low lipophilicity impairs its penetration through skin and efficacy as antimelanogenic agent indeed. Accordingly, this paper reports the assessment of several coumaric acid derivatives as tyrosinase inhibitors and antimelanogenic agents in in vitro, in silico and ex vivo assays. The compounds were designed with modifications in the aromatic and acid moieties of p-coumaric acid, being the coumarate esters the most promising derivatives. The compounds showed higher tyrosinase inhibitory activity (pIC(50), 3.7-4.2) than the parent acid, being compounds 1d, 1e and 1f the most potent inhibitors. Docking analysis showed that these esters are competitive inhibitors per se, and act independently of a redox mechanism as suggested by DPPH assays. Moreover, the esters showed efficacy in reducing the melanin deposition in human skin fragments at 0.1% concentration, especially compound le. In summary, there is an important equilibria between tyrosinase affinity and lipophilicity that must be considered to get effective antimelanogenic agents with adequate permeability in the skin.

In the present study, the effect of enzyme pretreatment on essential oil recoveries from sweet basil (Ocimum basilicum L.) leaves was evaluated. Moreover, the consideration on the use of hydrodistilled residue by-products as a source of bioactive phytochemicals with antioxidant, antimicrobial, and repellent effects against the stored-grain pest Tribolium castaneum was examined. Results showed that the enzymatic pretreatment increased the extraction yield of essential oil by 400, 417, and 478% in hemicellulase-, cellulase-, and viscozyme-treated samples, respectively. Phenylpropanoids including methyl cinnamate, methyl eugenol, eugenol and estragol were found as the main components, and were particularly abundant in cellulase-treated samples. From the hydrodistilled residue of enzyme-treated samples, better recoveries of total phenols (TPC) (258.3-470.9 mg GAE/g extract) and flavonoids (TFC) (59.4-94.3 mg QE/g extract) were observed. Using the DPPH, ABTS, and FRAP assays, a strong antioxidant activity of the rosmarinic-rich extract was observed. Such an activity which was mediated through electron transfer mechanism was highly correlated with the TPC, TFC and rosmarinic acid content. The in vitro bioassay showed that methanol extract (6.29 and 12.58 mu L/cm(2)) had repellent activity against the stored-grain pest Tribolium castaneum. These results suggest the potential of enzyme pretreatment to promote the use of hydrodistilled residue by-products as a valuable source of natural antioxidants and repellents ingredients.

There is a lot of interest in the development of new, safer and more sustainable polar aprotic solvents due to their importance in industrial applications and significant safety issues with the most commonly used examples. One such area of application is in pharmaceutically relevant C-C coupling reactions, where polar aprotic solvents are commonly used for solubility and to stabilise reaction intermediates. Although there are now a number of excellent alternatives in the literature, to date they have not been compared in a single study. This study demonstrates the effectiveness of the green solventsN-butylpyrrolidinone (NBP), gamma-valerolactone (GVL), propylene carbonate (PC) and dihydrolevoglucosenone (Cyrene) in Heck and Baylis-Hillman reactions. Good conversions and initial rates were observed in GVL and NBP in Heck reactions. Cyrene exhibited high initial rates of reaction and high yields in the Baylis-Hillman reaction. This demonstrates Cyrene to be a promising alternative polar aprotic solvent for this reaction.

Many classical and emerging methodologies in organic chemistry rely on carbon dioxide (CO2) extrusion to generate reactive intermediates for bond-forming events. Synthetic reactions that involve the microscopic reverse-the carboxylation of reactive intermediates-have conventionally been undertaken using very different conditions. We report that chemically stable C(sp(3)) carboxylates, such as arylacetic acids and malonate half-esters, undergo uncatalyzed reversible decarboxylation in dimethylformamide solution. Decarboxylation-carboxylation occurs with substrates resistant to protodecarboxylation by Bronsted acids under otherwise identical conditions. Isotopically labeled carboxylic acids can be prepared in high chemical and isotopic yield by simply supplying an atmosphere of (CO2)-C-13 to carboxylate salts in polar aprotic solvents. An understanding of carboxylate reactivity in solution enables conditions for the trapping of aldehydes, ketones, and alpha,beta-unsaturated esters.

Methyl cinnamate (M-1) and maleic anhydride (M-2), which are both non-homopolymerizable 1,2-disubtituted vinyl monomers, were radically copolymerized in toluene to result in 1:1 alternating copolymers. The 1:1 alternating sequence was confirmed by not only the monomer reactivity ratios obtained by using the terminal model fitted by the Kelen-Tiidos method (r(1) = 0.0035, r(2) = 0.069) but also MALDI-TOF-MS analysis of the copolymers with controlled molecular weights and relatively narrow molecular weight distributions (M-w/M-n = 1.20), which were prepared by RAFT copolymerization using 2-cyano-2-propyl ethyl trithiocarbonate (CPETC) as the RAFT agent. The maleic anhydride unit was transformed into two methyl ester groups by hydrolysis followed by methylation. Since the propagation of methyl cinnamate occurred regioselectively via a styrenic radical, the methyl esterified copolymers possessed ABAA sequence-controlled substituted polymethylene structures (A: methyl ester, B: phenyl). The sequence-controlled substituted polymethylene showed good thermal properties (T-d5 = 323 degrees C, T-g >= 192 degrees C) due to the rigid main-chain structures, which possessed a phenyl group on every fourth main-chain carbon in the repeating units in addition to three methyl ester groups on the other main-chain carbons. Block copolymers consisting of the rigid substituted polymethylene and soft poly(methyl acrylate) were also synthesized by RAFT polymerization.
