Hemoglobin's α‐Helix‐to‐β‐Sheet Transition Enables Targeted mRNA Delivery to the Lung

Advanced Science, EarlyView.
Acidic heating converts hemoglobin into β‐sheet‐rich fibrils with positively charged surfaces. These hemoglobin fibrils electrostatically complex IL‐11 scFv mRNA, selectively bind circulating platelets, and hitchhike to the lung, where they are enriched in fibroblasts.

Preparation, Component Identification, and Antioxidant Activity of Anthocyanins From Punica granatum “Tunisia”

AgriFood: Journal of Agricultural Products for Food, EarlyView.
The preparation for Tunisian pomegranate anthocyanin extract. The molecular mechanisms underlying the antioxidant effects of these compounds were investigated using network pharmacology and molecular docking. Antioxidant activity was evaluated through DPPH, ABTS, and FRAP assays, whereas the effects on oxidative stress and inflammation were examined in

Redirecting a Native Ene‐Reductase Toward Desaturation With Reverse Enantioselectivity

Angewandte Chemie, EarlyView.
A native ene‐reductase, XenA, was repurposed to catalyze the reverse‐enantioselective desaturation of cyclohexanones. The final variant was obtained through extensive protein engineering, combining PROSS‐guided computational design with mutagenesis and screening.

Citrus aurantium honey‐mediated gut homeostasis and anti‐inflammation via Thorl/Nprl2‐TORC1 signaling: Network pharmacology and Drosophila validation

Animal Models and Experimental Medicine, EarlyView.
The study employed a four‐tiered strategy: (1) UHPLC‐FTMS profiling of Citrus aurantium honey to characterize its chemical composition; (2) network pharmacology analysis integrating target prediction, protein–protein interaction networks, and KEGG pathway enrichment to identify the Thor1/Nprl2‐TORC1 axis as a key mechanistic pathway; (3) in vitro ...

Perilipin‐2‐Anchored Lipid Droplet‐Targeting Phototheranostics

Angewandte Chemie, EarlyView.
This study reports two NIR theranostic dyes, C‐BDP‐OH and C‐BDP‐OMe. C‐BDP‐OMe targets lipid droplets via a dual‐anchoring mechanism with PLIN2, enabling wash‐free tumor imaging. With 62.6% photothermal conversion efficiency, it achieves tumor ablation by downregulating PLIN2, disrupting LD‐mitochondria crosstalk, and triggering apoptosis and ...

Chrysin alleviates pressure overload–induced myocardial remodeling through regulating the PI3K/AKT/NRF2 pathway–mediated oxidative stress response

Animal Models and Experimental Medicine, EarlyView.
In this study, we primarily simulated pathological myocardial remodeling induced by transverse aortic constriction surgery and found significant cardiac hypertrophy and fibrosis, characterized by deteriorated cardiac function. Oxidative stress response is considered as a pivotal pathological process, which contributes to inflammation and apoptosis of ...

Unlocking a Nitrosuccinate Lyase for Decarboxylative Enzymatic Hydronitration

Angewandte Chemie, EarlyView.
The nitrosuccinate lyase CreD catalyzes C–NO2 bond formation using nitrite in water and shows synthetic practicality with high turnover numbers up to 102,000. A combination of protein engineering and computational methods helped to reveal the mechanistic principles that underpin this unique enzymatic activity.
