De novo formation of an aggregation pheromone precursor by an isoprenyl diphosphate synthase-related terpene synthase in the harlequin bug. [PDF]

, 2018
Insects use a diverse array of specialized terpene metabolites as pheromones in intraspecific interactions. In contrast to plants and microbes, which employ enzymes called terpene synthases (TPSs) to synthesize terpene metabolites, limited information ...

S100A14 in Tumor‐Derived EVs Targets PIAS3 to Reprogram Astrocytes and Induce Immunosuppressive Microenvironment Promoting Brain Metastasis and Germacrone Reversal Effect

Advanced Science, EarlyView.
This study identifies S100A14 in tumor‐derived exosomes as a key driver of brain metastasis. S100A14 targets PIAS3 in astrocytes, activating STAT3 signaling and promoting immunosuppressive MDSCs recruitment via chemokine secretion. Germacrone, a natural compound, binds S100A14 to disrupt this axis, effectively inhibiting brain metastasis with low ...

Reactivity of (3-Methylpentadienyl)iron(1+) Cation: Late-stage Introduction of a (3-Methyl-2Z,4-pentadien-1-yl) Side Chain [PDF]

, 2016
The 3-methyl-2Z,4-pentadien-1-yl sidechain is found in various sesquiterpenes and diterpenes. A route for the late stage introduction of this functionality was developed which relies on nucleophilic attack on the (3-methylpentadienyl)iron(1+) cation ...

Purification, Fluorescent Labeling, and Detyrosination of Mammalian Cell Tubulin for Biochemical Assays

Cytoskeleton, EarlyView.
ABSTRACT Microtubules play essential roles in numerous cellular processes. All microtubules are built from the protein tubulin, yet individual microtubules can differ spatially and temporally due to their tubulin isotype composition and post‐translational modifications (PTMs).

Effect of Fruit Maturation Stage on the Chemical Composition and Antioxidant and Cytotoxic Activities of Piper nigrum Essential Oil

Flavour and Fragrance Journal, EarlyView.
The essential oils of Piper nigrum show marked chemical and biological variation across fruit maturation stages. Ripe fruits yield oils with the strongest antioxidant and cytotoxic activities, demonstrating that maturation directly modulates volatile composition and enhances the bioactive potential of this aromatic species.
