Metabolic Engineering Optimizes Bioorthogonal Glycan Labeling in Living Cells [PDF]

, 2021
Metabolic oligosaccharide engineering (MOE) has fundamentally contributed to our understanding of protein glycosylation. Efficient MOE reagents are activated into nucleotide-sugars by cellular biosynthetic machineries, introduced into glycoproteins and ...

Mesenchymal Stromal Cell‐Based Cell–Drug Conjugates for the Treatment of Acute Liver Failure

Advanced Science, EarlyView.
Mesenchymal stromal cell (MSC)‐based cell‐drug conjugates are constructed by anchoring rosiglitazone‐loaded nanoparticles onto the MSC surface. Sustained rosiglitazone release enhances MSC proliferation and paracrine activity while promoting anti‐inflammatory macrophage polarization.

Evaluation of Pyrones in Bioorthogonal Reactions: Correlation between Structure, Reactivity, and Bioorthogonality

The Journal of Organic Chemistry
Alpha-pyrones have been used for applications ranging from total synthesis to antibiotics. However, their application as dienes in bioorthogonal reactions has not been extensively explored. In previous work, we demonstrated the promising application of ester-functionalized pyrones in bioorthogonal protein labeling.

Photoactivated Platinum Complexes: Targeting Membrane Proteins and Organelles for Precision Cancer Therapy

Angewandte Chemie, EarlyView.
This review highlights an emerging anticancer approach integrating platinum agents into photodynamic therapy (PDT) and photoactivated chemotherapy (PACT) systems, further augmented by cancer cell membrane‐ and organelle‐targeting. By directing photoactivated platinum complexes from nontargeted distribution to cancer cells or defined subcellular sites ...

Structure and Biosynthesis of Mangotoxin Produced by the Plant Pathogen Pseudomonas syringae

Angewandte Chemie, EarlyView.
The structure of mangotoxin remained elusive for over two decades. Here, mangotoxin was isolated from the native producer, Pseudomonas syringae pv. syringae, and was determined to be an alkyne‐containing dipeptide. Mangotoxin inhibited the growth of multidrug‐resistant human pathogen Klebsiella pneumoniae.

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

Advanced 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 ...
