A single‐molecule prodrug synergistically suppresses MYC‐amplified osteosarcoma through sequential nitric oxide release and photodynamic therapy

open access: yesSmart Molecules, EarlyView.
A cascade‐responsive small‐molecule prodrug (DHU‐NO3) sequentially releases methylene blue (triggered by reactive oxygen species) and nitric oxide (controlled by 405 nm light), enabling precise spatiotemporal coordination of photodynamic therapy and NO gas therapy to effectively inhibit MYC‐amplified osteosarcoma growth.

Modular Synthesis of α‐Quaternary Pyrrolines by Pyridoxal‐Catalyzed Sequential Reactions With Precise Chirality Relay

open access: yesTransformative Chemistry, EarlyView.
Direct asymmetric α‐C conjugate addition of aminoacetonitrile enabled by carbonyl/iminium double activation, together with subsequent electrophilic functionalization, offers a one‐pot, two‐step modular strategy for synthesizing chiral α‐quaternary pyrrolines with precise chirality relay and high structural diversity.

Electrochemical Reductive β‐Arylation and Alkenylation of α‐Branched Acroleins by Primary Amine/Nickel Dual Catalysis

open access: yesTransformative Chemistry, EarlyView.
A synergistic primary amine/nickel catalysis under electrochemical conditions was developed for cathodic β‐arylation and alkenylation of α‐branched acroleins. The reaction proceeds through β‐enaminyl radicals generated by cathodic reduction of an iminium ion allowing smooth coupling with aryl‐ or alkenyl‐Ni(II) species.

Sulfur‐ and Selenium‐Decorated Coumarins: Synthetic Strategies Involving Cyclization and Late‐Stage Functionalization

open access: yesThe Chemical Record, EarlyView.
Two decades of synthetic strategies for sulfur‐, selenium‐decorated coumarins are critically surveyed through 44 literature reports, with particular emphasis on derivatives functionalized at the C‐3 and C‐4 positions. This review reports the direct construction of the coumarin framework through cyclization processes and late‐stage functionalization of ...

Investigation of the Protective Effect of Morin on Oxidative Stress and Apoptosis in Malathion‐Induced Hepatotoxicity in Rats

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Malathion (MAL) is a widely used organophosphate pesticide associated with hepatotoxicity through oxidative stress and apoptosis. Morin, a naturally occurring flavonoid, exhibits potent antioxidant and anti‐inflammatory properties. This study investigated oxidative stress, inflammatory, and apoptotic alterations induced by acute and subacute ...
