Mikroskaliges Tätowieren von Hydrogelen und Zellen: benzoxaborolbasierter Mikrokontaktdruck (µCP) auf glykolisierte Oberflächen

open access: yesAngewandte Chemie, Volume 137, Issue 35, August 25, 2025.
Wir zeigen ein polymergestütztes Mikrokontaktdruckverfahren (µCP) zur Strukturierung glykosylierter Oberflächen. Als Tinte für die Oberflächenstrukturierung verwendeten wir ein Benzoboraxol‐Derivat. Mit dieser neuartigen Methode konnten wir Waferoberflächen mit Glykopolymerfilmen, oberflächen‐glykosylierten Polymermikropartikel sowie zelluläre ...

Update: Enzymatische Synthese für industrielle Anwendungen

open access: yesAngewandte Chemie, Volume 137, Issue 27, July 1, 2025.
Die Biokatalyse hat sich zu einer nachhaltigen und wettbewerbsfähigen Alternative zur herkömmlichen chemischen Synthese entwickelt und ermöglicht die enzymbasierte Herstellung nicht nur von chemischen Grundstoffen, sondern auch von (nicht natürlichen) Aminosäuren, (seltenen) Zuckern und synthetischen Nukleotiden.

An Update: Enzymatic Synthesis for Industrial Applications

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 27, July 1, 2025.
Biocatalysis has become a sustainable and cost‐competitive alternative to established chemical synthesis, enabling the enzyme‐based production of not only commodity chemicals but (non‐natural) amino acids, (rare) sugars, as well as synthetic nucleotides.

Optimization of inulin extraction from Inula helenium L. using response surface methodology followed by its MALDI-TOF and TLC-FLD based characterization

open access: yesJournal of Medicinal Plants, 2022
Background: Inulin, a prebiotic, is a mixture of linear chains β-2,1 fructans with a degree of polymerization (DP) of 2 to 60. Different DPs have various applications in the cosmetics, pharmaceutical, and food industries.

Overexpression of Transketolase Relieves xylA Repression and Enhances Xylose Utilization in Saccharomyces cerevisiae During Mixed Sugar Fermentation

open access: yesGCB Bioenergy, Volume 17, Issue 7, July 2025.
To overcome the bottleneck of inefficient xylose utilization in lignocellulosic bioethanol production, we constructed a recombinant Saccharomyces cerevisiae strain (INVSc‐xylA‐Xltr1p‐TKL1) by overexpressing the transketolase gene TKL1. This engineering strategy significantly enhanced xylose consumption by 33%, upregulated xylose isomerase (xylA ...

A Biocatalytic Cascade for the Valorization of Sugars

open access: yesChemCatChem, Volume 17, Issue 12, June 23, 2025.
We report a one‐pot, three‐step biocatalytic cascade to synthesize trihydroxy‐piperidine and ‐azepane iminosugars directly from monosaccharides, employing transaminase (ATA) and galactose oxidase (GOase) enzymes. Abstract Biocatalytic cascades offer products of multistep synthesis without the use of protecting groups or isolation of intermediates. This

The Novel Dual GIP and GLP‐1 Receptor Agonist Tirzepatide Attenuates Colon Cancer Development by Regulating Glucose Metabolism

open access: yesAdvanced Science, Volume 12, Issue 19, May 22, 2025.
Tirzepatide, a dual GIP/GLP‐1 receptor agonist for diabetes, suppresses colorectal cancer growth by targeting glucose metabolism. It inhibits cancer cell proliferation, promotes apoptosis, and induces tumor regression. It reduces glucose uptake and destabilizes HIF‐1α for degradation to downregulate PFKFB3/PFK‐1 enzymes, thus contributing to the ...

Characteristic metabolite profile of 10 colorectal cancer-related bacteria

open access: yesFrontiers in Oncology
BackgroundTumor metabolomics of colorectal cancer (CRC) is significantly different from normal tissues, due to nutrient deprivation, metabolite accumulation, acidity and hypoxia. Besides, gut microbiota has been confirmed to affect the progression of CRC.
