Harnessing the Biological Responses Induced by Nanomaterials for Enhanced Cancer Therapy

Aggregate, EarlyView.
Nanomaterial (NM)‐induced toxicity can be strategically repurposed for cancer therapy. This review summarizes the mechanism by which NMs selectively activate specific cellular processes to regulate cell fate independently. We also discussed how NMs‐induced biological responses can be leveraged as therapeutic strategies for cancer treatment.

Zwitterionic Heavier Pnictinidenes in Redox Catalysis

Angewandte Chemie, EarlyView.
Zwitterionic pnictinidenes: A new class of zwitterionic heavier pnictogen species stabilized by bis(N‐heterocyclic carbene)borate ligands is reported, enabling the isolation of Sb and Bi in multiple oxidation states. These thoroughly characterized systems exhibit cationic character and engage in redox catalysis, facilitating catalytic ...

Elucidating the Fe(III) Directed 15‐Step Domino Inter‐ and Intramolecular Progressive Coordinative Oligomerization of a Heterocycle Aggregate

Aggregate, EarlyView.
A domino reaction leading to the novel heterocyclic aggregate 2,9‐dihydrobenzo[b]cyclopenta[e][1,4]thiazine has been developed, with its mechanism elucidated by crystallography and ESI‐MS to reveal a 15‐step reaction sequence (the longest reported to date) involving intermolecular C‐C coupling and intramolecular expansion.

Redox‐ and NIR‐Active Iron(III) Triradicals as Catalysts for Radical Polymerization of Acrylamides and Methacrylates

Angewandte Chemie, EarlyView.
A redox‐active low‐spin Fe(III)‐triradical complex was isolated in good yield and utilized as a catalyst for radical polymerization of acrylamides and methacrylates at ambient conditions. Abstract Two unprecedented redox‐active, low‐spin Fe(III)‐triradical complexes, [Fe(III)(SS‐NHC═S•−)3]·NHC═S (1·NHC═S; E═S) and [Fe(III)(SS‐NHC═Se•−)3] (2; E═Se) have

Supramolecular Probe for Monitoring Lysosomal Ferritinophagy to Facilitate the Early Diagnosis of Parkinson's Disease

Aggregate, EarlyView.
A supramolecular fluorescent probe, TPE‐4B/4Q[7], was designed to target lysosomes. The restriction of intramolecular rotation effect mediated by Q[7] enhances the fluorescence of TPE‐4B/4Q[7], enabling selective detection of Fe3+ with a detection limit of 1.23 × 10⁻⁶ M.

Light‐Driven Ratchet Mechanism Accelerates Regioselective Metal‐Cation Exchange in a Heterobimetallic Helicate

Angewandte Chemie, EarlyView.
Photoswitchable homo‐ and heterobimetallic helicates form with high diastereo‐ and regioselectivity via single‐step self‐assembly or self‐sorting. White‐light exposure autonomously operates one helicate as a molecular ratchet, promoting the selective formation of an out‐of‐equilibrium structure.

Hydrophobically modified Cu2O nanocube for selective CO2 electroreduction to C2+ products

AIChE Journal, EarlyView.
Abstract The electrochemical conversion of CO2 into carbonaceous fuels and chemicals emerges as a promising sustainable strategy toward energy‐rich chemical feedstocks. However, CO2 reduction reaction (CO2RR) in aqueous environments is highly intricate, as protons may be directly reduced to H2.

The Iron–Sulfur Cluster of Bacterioferritin‐Associated Ferredoxin (Bfd): a “Biological Fuse” that Prevents Oxidative Damage to Cells?

Angewandte Chemie, EarlyView.
When cellular iron is low, bacterioferritin (Bfr) releases its stored iron through a reductive process dependent on the [2Fe–2S] ferredoxin Bfd. Why accessing stored iron should depend on an iron‐requiring protein when iron is scarce is unclear. Here, we show that the Bfd [2Fe–2S] cluster is sensitive to oxidative stress, suggesting that it may act as ...
