Lonicera macranthoides is an important medicinal plant widely used in traditional Chinese medicine. Luteoloside is a critical bioactive compound in L. macranthoides. To date, the molecular mechanisms underlying luteoloside biosynthesis are still largely unknown. In this work, high performance liquid chromatography (HPLC) was employed to determine the luteoloside contents in leaves, stems, and f...

El objetivo del estudio fue evaluar el efecto de la adición ácido ascórbico (AA) al medio vitrificación folículos preantrales (FPs) bovinos previamente enfriados a 4 °C durante o 24 h. Se recolectaron ovarios novillas Nelore los 14 meses edad. En laboratorio se extrajeron fragmentos ovario región cortical y distribuyeron para control fresco (C0h), refrigeración ºC por horas en TCM-199 más HEPES...

The "perturbation" effects (i.e. hyperconjugation, electronegativity, and conjugation) on the structural, electronic, and magnetic properties of three kinds of two-dimensional (2D) X-Cr-X (X = C4H, NC3 and BC3 monolayers) sandwich nanostructures were systematically investigated by means of spin-polarized density functional theory (DFT) computations. Although all these 2D sandwich systems energe...

Cinnamic acid and cinnamate derivatives have gained attention due to their potential protective role against oxidative damage diseases, such as coronary heart disease, stroke and cancers. However, their potential interest for the human health goes far beyond their protective antioxidant behaviour. The present review encompasses the involvement of cinnamate and its derivatives against various ch...

BACKGROUND Zinc layered hydroxide (ZLH) intercalated with cinnamate, an anionic form of cinnamic acid (CA), an efficient UVA and UVB absorber, have been synthesized by direct method using zinc oxide (ZnO) and cinnamic acid as the precursor. RESULTS The resulting obtained intercalation compound, ZCA, showed a basal spacing of 23.9 Å as a result of cinnamate intercalated in a bilayer arrangemen...

Posttranslational modifications can cause profound changes in protein function. Typically, these modifications are reversible, and thus provide a biochemical on-off switch. In contrast, proline residues are the substrates for an irreversible reaction that is the most common posttranslational modification in humans. This reaction, which is catalyzed by prolyl 4-hydroxylase (P4H), yields (2S,4R)-...

4-Coumarate:coenzyme A ligase (4CL) plays a key role in phenylpropanoid metabolism, providing precursors for a large variety of important plant secondary metabolites, such as lignin, flavonoids, and phytoalexins. Although 4CLs have been believed to be specific to plants, a gene encoding a 4CL-like enzyme which shows more than 40% identity in amino acid sequence to plant 4CLs was found in the ge...
