Phenolic Profile and Bioactive Prospects of Wild Annona Species From Angola

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
ABSTRACT Annona species (Annonaceae family) are valued for their nutritional and medicinal importance, especially in traditional medicine. This study investigated the phenolic profiles of the Angolan Annona muricata, Annona squamosa, and Annona senegalensis leaves, stem barks, and seeds hydroethanolic, infusion, and decoction extracts, also evaluating ...

Characterising the Effect of Cultivar and Roasting Temperature on FT‐NIR Spectral Data of Wheat Using ASCA

Journal of Chemometrics, Volume 40, Issue 2, February 2026.
ABSTRACT The physicochemical and functional properties of wheat can be modified by exposing the whole grains to thermal pretreatment. Conventional analytical methods used to investigate such modifications are expensive, labour‐intensive and may be inaccurate due to interfering compounds.

Technologies and Strategies for Metabolic and Molecular Imaging With Hyperpolarized MRI

Journal of Magnetic Resonance Imaging, Volume 63, Issue 2, Page 310-327, February 2026.
ABSTRACT Conventional Magnetic Resonance Imaging (MRI) offers limited sensitivity for direct metabolic and molecular imaging using non‐proton nuclei due to low thermal nuclear spin polarization. Hyperpolarization (HP) technologies increase nuclear spin polarization by several orders of magnitude, overcoming this limitation to enable in vivo studies of ...

The Crystal Structure of Human Transport and Golgi Organization 2 Homolog (TANGO2) Protein Reveals an αββα‐Fold Arrangement

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 2, Page 515-528, February 2026.
ABSTRACT Transport and Golgi Organization 2 Homolog (TANGO2) protein deficiency disorder (TDD) is a rare autosomal recessive disorder characterized by multi‐systemic abnormalities and significant phenotypic variability including neurodevelopmental delay, seizures, intermittent ataxia, hypothyroidism, rhabdomyolysis, life‐threatening metabolic ...

On‐Resin Pictet–Spengler Cyclization for 1,2,3,4‐Tetrahydro‐β‐carboline‐3‐carboxylate (Tcc) Peptide Synthesis With Acid‐Labile Functional Tolerance

Journal of Peptide Science, Volume 32, Issue 2, February 2026.
The constrained tryptophan (Trp) analog 1,2,3,4‐tetrahydro‐β‐carboline‐3‐carboxylic acid (Tcc) is used to restrict peptide conformation in structure–activity relationship studies. Although Pictet–Spengler cyclization of Trp and aldehydes with mineral acid gives Tcc analogs, such harsh conditions do not tolerate acid‐labile functionality.

From Plastic Waste to Pharmaceutical Precursors: PET Upcycling Through Ruthenium Catalyzed Semi‐Hydrogenation

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
We present a new catalytic process that converts real‐life PET waste into ethyl 4‐hydroxymethylbenzoate (EHMB), which serves as a valuable intermediate for the synthesis of pharmaceuticals, an insecticide, and a novel polyester. Abstract We report here the upcycling of PET (polyethylene terephthalate) waste via semihydrogenation to make ethyl 4 ...

Carboxydotrophic Acetogenesis in Alkaline Conditions Results in Transient Formate Production by the Halo‐Alkaliphilic Acetogen Haloacetibacter carboxydivorans Gen. Nov. sp. Nov

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This work presents the physiological exploration of the halo‐alkaliphilic, carboxydotrophic acetogen bacterium MD4. In contrast to well‐characterised neutrophilic and slightly acidophilic acetogenic carboxydotrophs, this work shows an important role for formate production, instead of ethanol, as a redox exhaust mechanism in alkaline conditions ...
