2,2’-dipyridylamine (DPA) is hereby firstly reported as a novel and efficient tridentate ligand for promoting copper(I)-catalyzed C-O/S coupling reactions of abundant aryl bromines with related phenols or thiophenols. The key to this very discovery is the identification of an N-donor tripod ligand (DPA), and such a reaction allows the conversion of simple starting materials to complex diaryl ethers or diaryl thioethers, which are important synthetic intermediates in the preparation of bioactive molecules.

Gustatory systems in phytophagous insects are used to perceive feeding stimulants and deterrents, and are involved in insect decisions to feed on particular plants. During the process, gustatory receptors (Grs) can recognize diverse phytochemicals and provide a molecular basis for taste perception. The silkworm, as a representative Lepidoptera species, has developed a strong feeding preference for mulberry leaves. The mulberry-derived flavonoid glycoside, isoquercetin, is required to induce feeding behaviours. However, the corresponding Grs for isoquercetin...

Patients with chronic obstructive pulmonary disease (COPD) suffer from persistent cough and breathlessness, which can be ameliorated by the Chinese herbal medicine glycyrrhiza. Furthermore, the SRC/MAPK pathway is activated in the process of oxidative stress and inflammation, which afflict COPD progression. Thus, this research aimed at dissecting the mechanism of compound glycyrrhiza oral solution (CGOS) relieving oxidative stress and inflammation in COPD via the SRC/MAPK pathway. After a COPD rat model was established using lipopolysaccharide...

The nutritional values of the protein are related to its amino acid content, and its physicochemical properties. We aimed to determine the relationship between the variation of protein digestibility or the releasing coefficient of amino acids with the physicochemical properties of different feedstuffs. We analysed the secondary protein structure and solubility of 10 protein-rich feed ingredients, including soybean, soybean meal, dehulled soybean meal, fermented soybean meal, distiller’s dried grains with solubles (DDGS), feather meal, fish...

Cervical cancer (CC) is one of the most prevalent malignancies among females. Cytoprotective autophagy could confer cancer cell tolerance to hypoxic stress, promoting cell survival and adaptation. Aspartyl-tRNA synthetase 1 antisense 1 (DARS-AS1) is an oncogenic long non-coding RNA (lncRNA) in various cancers, but how DARS-AS1 regulates cytoprotective autophagy in hypoxic environment in CC remains unclear. Chromatin immunoprecipitation (ChIP) and luciferase reporter assays were conducted to explore the interaction between hypoxia-inducible factor 1 subunit alpha...

A stereo interplanting system with foxtail millet beneath chestnut trees is an effective planting method to raise the utilization of land in chestnut orchards, increase yields and improve quality of chestnut nuts. Consequently, exploration of genes involved in shade tolerance response in foxtail millet and breeding shade-tolerant varieties have become urgent issues. In this study, RNA-seq of leaf samples from two shade-tolerant varieties and three shade-intolerant varieties of foxtail millet at the booting stage was...
