Degrading GPX4 via Biomimetic Nanoparticle‐Mediated In Situ Synthesis of Deep‐Learning‐Designed Binder‐Degron Chimeras for Prostate Cancer Therapy

open access: yesAdvanced Science, EarlyView.
A deep‐learning‐designed binder is fused to a combinatorial degron to create a binder‐degron chimera (bdC) that recruits the CUL2‐RING ubiquitin ligase complex. Encapsulation in a prostate‐cancer‐targeted, CD47‐camouflaged nanocarrier enables tumor‐specific in situ bdC expression, triggering GPX4 degradation and ferroptosis, thereby establishing a ...

Recoding the Genetic Code with Selenocysteine [PDF]

open access: yesAngewandte Chemie International Edition, 2013
AbstractSelenocysteine (Sec) is naturally incorporated into proteins by recoding the stop codon UGA. Sec is not hardwired to UGA, as the Sec insertion machinery was found to be able to site‐specifically incorporate Sec directed by 58 of the 64 codons.

Mechanisms Affecting the Biosynthesis and Incorporation Rate of Selenocysteine

open access: yesMolecules, 2021
Selenocysteine (Sec) is the 21st non-standard proteinogenic amino acid. Due to the particularity of the codon encoding Sec, the selenoprotein synthesis needs to be completed by unique mechanisms in specific biological systems.

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.

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 ...

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

open access: yesBMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Harnessing the Reactivity of Sulfinate Salts With Cystine: An Umpolung Approach to Residue‐Specific Peptide Modification

open access: yesAngewandte Chemie, Volume 138, Issue 37, 7 September 2026.
While cysteine is widely employed as a nucleophilic handle for peptide modification, the electrophilicity of the oxidized form, cystine, is rarely exploited. This study describes a mild, photochemical coupling of sulfinate salts with peptide disulfides.

Role of selenium in the pathophysiology of cardiorenal anaemia syndrome

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 770-780, April 2025.
Abstract Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)].
