Catechol Containing Polyelectrolyte Complex Nanoparticles as Local Drug Delivery System for Bortezomib at Bone Substitute Materials

Pharmaceutics, 2020
The proteasome inhibitor bortezomib (BZM) is one of the most potent anti-cancer drugs in the therapy of multiple myeloma. In this study, an adhesive drug delivery system (DDS) for BZM was developed.

Radiation‐Triggered Chemokine‐Secreting Probiotics for Boron Neutron Capture Therapy Based Radioimmunotherapy

Advanced Science, EarlyView.
Engineered Escherichia coli Nissle 1917 with a tannic acid‐mediated BPA coating enables tumor‐targeted boron delivery for BNCT. The low‐level incidental radiation generated during BNCT activate a RecA‐driven circuit to induce CXCL10, while radiation‐enhanced bacterial colonization triggers in situ vaccination and systemic antitumor immunity.

Hierarchical Flux‐Protection Engineering Stabilizes Oxidation‐Prone Metabolic Nodes for High‐Level Curcumin Biosynthesis

Advanced Science, EarlyView.
Flux‐protection engineering stabilizes an oxidation‐prone L‐DOPA node in engineered E. coli by combining acid‐adapted chassis evolution, respiratory‐chain modulation, enzyme‐level flux matching, and pH–DO control. Carbon is redirected from oxidative browning to productive biosynthesis, enabling 1075.2 mg/L curcumin and demonstrating transferability to ...

Meirols A–C: Bioactive Catecholic Compounds from the Marine-Derived Fungus Meira sp. 1210CH-42

Marine Drugs
Three new catecholic compounds, named meirols A–C (2–4), and one known analog, argovin (1), were isolated from the marine-derived fungus Meira sp. 1210CH-42. Their structures were determined by extensive analysis of 1D, 2D NMR, and HR-ESIMS spectroscopic

Supramolecular Zinc–Polyphenol Coordination Assemblies Mitigate Colonic Inflammation by Regulating Mucosal Barrier and Microbiome

Advanced Science, EarlyView.
A carrier‐free zinc‐coordinated polyphenol nanoplatform (ZnCA NPs) is designed as an “all‐in‐one” therapeutic strategy for intestinal inflammation. The ZnCA NPs exhibit enhanced colonic accumulation and broad‐spectrum reactive oxygen and nitrogen species scavenging.

Sequential Regulation of Neurovascular Bone Regeneration in Large Bone Defects Using Black Phosphorus‐Europium Nanosheet Integrated TPMS Biomimetic Scaffold with Photo‐Controlled Ion Release

Advanced Science, EarlyView.
TPBE scaffolds, in conjunction with mild photothermal effects, effectively activate the PI3K/Akt signaling cascade, thereby promoting early neuronal differentiation and neurite growth. Short‐term (12 W) in vivo implantation studies revealed no significant pathological damage to major organs, providing preliminary evidence of the material's excellent ...
