Biomimetic Nanofiber Scaffold Coated With Acellular Matrices for Uterine Myometrial Tissue Engineering

open access: yesAdvanced NanoBiomed Research, EarlyView.
Schematic representation of acellular matrix generation from human uterine fibroblast cells, coating on polycaprolactone electrospun nanofibers, and subsequent in vitro and in vivo characterization. A tissue‐engineered scaffold tailored for uterine myometrium‐specific regeneration is designed. The electrospinning technique was used to fabricate aligned

A DNA G‐Quadruplex‐Targeting Ligand Suppresses c‐MYC Expression: Implications for Gemcitabine‑Resistant Pancreatic Cancer

open access: yesAngewandte Chemie, EarlyView.
PQB‐4, a fluorescent small‐molecule ligand that targets c‐MYC DNA G‐quadruplexes (G4s), showed marked synergy with gemcitabine in resistant PANC‐1 cells (CI = 0.027). In vivo, the ligand reduced tumor weight by 44% in a PANC‐1 xenograft model. These results highlight the therapeutic potential of c‐MYC DNA G4‐targeting ligands for treating gemcitabine ...

Rational Design of a Synthetic Galliphore for the Diagnostic Nuclear Imaging and Treatment of Bacterial Infections

open access: yesAngewandte Chemie, EarlyView.
KO‐NH2 is a synthetic metallophore that preferentially binds Ga3+ over Fe3+ and is recognized by bacterial transporters. Photocrosslinking identifies CirA and Fiu as key uptake proteins in E. coli. KO‐NH2 enables targeted imaging and treatment of E. coli soft tissue infections.

Synthese und aktivitätsbasierte Proteinprofilierung identifizieren die Aldo‐Keto‐Reduktase 1C3 als Zielprotein der Myxoglucamide

open access: yesAngewandte Chemie, EarlyView.
Myxoglucamid A – ein neuartiges, aus Myxobakterien isoliertes Glykolipopeptid – wurde erstmals totalsynthetisch hergestellt. Mittels aktivitätsbasierter Proteinprofilierung (ABPP) wurde die Aldo‐Keto‐Reduktase 1C3 (AKR1C3) als primäres Zielprotein in menschlichen Zellen identifiziert.

Created Ex Nihilo: A Near‐Infrared Afterglow Luminescent Framework of Imidazole Derivatives for Bioimaging

open access: yesAngewandte Chemie, EarlyView.
A series of Ir(III) complexes (Ir‐1‐Ir‐4) based on imidazole derivatives provide a new afterglow luminescence mechanism. The work expands the range of afterglow luminescence frameworks to overcome: (i) a lack of new afterglow scaffolds; (ii) the dependence on initial external light activation; and (iii) aggregation‐caused quenching.

Photoinduzierte Freisetzung maskierter Iridium(III)‐Komplexe für die kombinierte photodynamische und photoaktivierte Chemotherapie

open access: yesAngewandte Chemie, EarlyView.
Lichtaktivierbare Iridium(III)‐Prodrugs zeigen, wie die Koordination von Chalkogenen die photoinduzierte therapeutische Aktivität steuert. Bei Bestrahlung mit sichtbarem Licht laufen an den schwefel‐ bzw. selenhaltigen Liganden unterschiedliche, sauerstoffabhängige Photoreaktionen ab.

Synthesis and Activity‐Based Protein Profiling Identifies Aldo‐Keto Reductase 1C3 as Target Protein of Myxoglucamides

open access: yesAngewandte Chemie International Edition, EarlyView.
Myxoglucamide A—a novel glycolipopeptide isolated from myxobacteria—was synthesized, and activity‐based protein profiling identified aldo‐keto reductase 1C3 (AKR1C3) as its main target in human cells. Structure‐activity relationship studies, together with biophysical characterization and X‐ray crystallography, elucidated the structural basis of AKR1C3 ...

Uncaging Iridium(III) Complexes for Combined Photodynamic and Photoactivated Chemotherapy

open access: yesAngewandte Chemie International Edition, EarlyView.
Light‐activatable iridium(III) anticancer prodrugs demonstrate how chalcogen coordination controls photoinduced therapeutic activity. Upon visible‐light irradiation, sulfur‐ and selenium‐based caging ligands undergo distinct oxygen‐dependent photoreactions that trigger ligand release and singlet oxygen generation, enabling combined photoactivated ...
