A C‐Nucleoside Analogue of Cordycepin With High Metabolic Stability and Potent Anti‐Psoriatic Activity via Microneedle Delivery

Advanced Science, EarlyView.
This work identified CPD3a as a potent, stable C‐nucleoside cordycepin derivative. When formulated into microneedle array for topical treatment, it ameliorated psoriasis by rebalancing immunity and enhancing antioxidant defenses. ABSTRACT Psoriasis is a chronic inflammatory disorder characterized by immune dysregulation and epidermal hyperplasia ...

Rational Molecular Design to Improve Digital Polymer Readout in Aerolysin‐Based Nanopore Sequencing

Angewandte Chemie, EarlyView.
Nanopore sensing holds significant yet underexplored potential for decoding synthetic digital polymers. In this study, we synthesized an extensive library of sequence‐defined poly(phosphodiester)s and evaluated their performance in aerolysin‐based sequencing. By systematically optimizing molecular parameters, we identified an ideal combination of coded

Chemical Bond‐Orchestrated Energy Depletion to Augment Lung Cancer Chemo‐Immunotherapy

Advanced Science, EarlyView.
This study grafted dichloroacetic acid (DCA) into perylenediimide (PDI) skeleton via ionic or covalent bond to create novel metabolic agent PDIC‐AC and PDIC‐NAC, explicitly elaborated the underlying energy metabolism and therapeutic mechanism, and developed a promising strategy for energy metabolism‐targeting chemo‐immunotherapy by chemical bond ...

Generation of the Camptothecin Scaffold by a Flavin‐Catalyzed Photooxidative Skeletal Reorganization

Angewandte Chemie, EarlyView.
The biosynthetic pathway of the anticancer drug precursor camptothecin involves an enigmatic skeletal reorganization from a 6/5/6 tetrahydro‐β‐carboline to a 6/6/5 pyrroloquinoline ring system. Here, we show that this transformation can be achieved by photooxidation with flavin cofactors, such as flavin mononucleotide (FMN) as catalysts.

LNP‐mediated in vivo base editing corrects Agxt to cure primary hyperoxaluria type 1

Clinical and Translational Medicine
Objective Primary hyperoxaluria type 1 (PH1) is a rare autosomal recessive disorder caused by AGXT mutations, leading to hepatic oxalate overproduction, nephrolithiasis, and progressive renal failure. This study aims to evaluate the therapeutic potential

Nucleoside‐Modified mRNA Encoding Alpha‐Galactosidase A Ameliorates Fabry Disease Phenotypes in Human IPSC‐Derived Cardiomyocytes

Advanced Science, EarlyView.
Human iPSC‐derived Fabry cardiomyocytes exhibited broad transcriptional dysregulation, apoptosis, mitochondrial dysfunction, impaired reactive oxygen species handling, altered contractility, and abnormal calcium transient decay, potentially mediated by phospholamban hyperphosphorylation.

Flavin Catalysts in Organic Synthesis

Angewandte Chemie, EarlyView.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

EBV‐Driven ODC1 Upregulation Enhances Polyamine Anabolism to Promote Viral Replication and Cisplatin Resistance in Nasopharyngeal Carcinoma

Advanced Science, EarlyView.
EBV‑BZLF1 initiates ODC1‑driven polyamine anabolism that correlates with poor clinical prognosis in nasopharyngeal carcinoma. The ODC1–spermidine axis promotes viral replication, cell proliferation and innate immune evasion. Pharmacological inhibition of ODC1 rescues cisplatin sensitivity, establishing ODC1 as a viable therapeutic target for EBV ...

Nitro Reduction‐Based RNA Control and Ultrafast Release

Angewandte Chemie, EarlyView.
A chemical RNA caging–uncaging strategy based on nitro reduction is described. Nitroaryl groups introduced via acylation temporarily block the functions of diverse RNAs in vitro and in living cells. Treatment with a diboronic acid–bipyridine mixture rapidly reduces the nitro groups, releasing RNAs and restoring their activity.
