Regioselective reactions of 3,4-pyridynes enabled by the aryne distortion model. [PDF]

open access: yes, 2013
The pyridine heterocycle continues to play a vital role in the development of human medicines. More than 100 currently marketed drugs contain this privileged unit, which remains highly sought after synthetically. We report an efficient means to access di-

Monodentate Phosphine Modulation in Cyclometallated Platinum(II) Complexes for Antileishmanial, Antiviral, and Antitumor Applications

open access: yesChemMedChem, Volume 21, Issue 4, 25 February 2026.
Schematic representation depicting the influence of phosphine ligand identity on the biological and physicochemical characteristics of Pt(II) complexes: PTA promotes antileishmanial activity, PPh2(Php–COOH) strengthens antiviral activity, and TCEP enhances fluorescence.

Ir(III) Complexes Convert Cold to Hot Tumors via Ferroptosis/Necroptosis‐Driven Immunogenic Cell Death and Photosensitized CD47 Downregulation

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
Red‐light‐activated Ir1 overcomes hypoxia tolerance and adapts to the immunosuppressive tumor microenvironment, converting immunologically cold tumors into inflamed hot microenvironments. This conversion is driven by synergistic induction of immunogenic cell death through coordinated ferroptosis‐necroptosis pathways and spatiotemporally controlled ...

A Hypoxia‐Responsive Near‐Infrared Phosphorescence Nanoprobe for High‐Sensitive Detection of Tumor Cells and Imaging of Colorectal Cancer In Situ

open access: yesAggregate, Volume 7, Issue 1, January 2026.
We have successfully developed a hypoxia‐responsive near‐infrared phosphorescent probe, Ir‐PEG. This nanoprobe demonstrates high sensitivity, water solubility, and deep‐tissue penetration. It remains specifically activatable even in the hypoxic intestinal environment, facilitating high‐contrast imaging of orthotopic colon cancer.

Photo‐Autocatalysis: Insights From Light‐Driven Self‐Catalyzed Organic Transformations

open access: yesChemistry – An Asian Journal, Volume 21, Issue 2, 28 January 2026.
This perspective highlights recent advancements in photo‐autocatalytic reactions—light‐driven processes characterized by self‐accelerating kinetics. We explore the underlying mechanisms, demonstrating how photo‐autocatalysis can be realized either through a single photo‐autocatalyst or through a combination of a photocatalyst and an autocatalyst, and ...

Substitution Kinetics, DNA/BSA Interactions, Cytotoxicity Evaluation and Computational Analysis of [bis‐(azaaryl)amine)Pt(II)/Pd(II)Cl] Complexes, Azaaryl = Quinoline or Phenanthridine

open access: yesBioinorganic Chemistry and Applications, Volume 2026, Issue 1, 2026.
The search for metal‐based anticancer agents with improved efficacy and reduced side effects is ongoing. The activities of these anticancer drugs depend on their aqueous stability, substitutional reactivity at target sites (cytotoxicity) and nontarget sites (toxicity), as well as their transportation and cell bioavailability.

Chinese Herbal Medicines for Diabetic Cardio‐Cerebrovascular Diseases: Key Bioactive Metabolites and Action Mechanisms

open access: yesJournal of Nutrition and Metabolism, Volume 2026, Issue 1, 2026.
Currently, the global incidence of diabetes is increasing, particularly in populous developing regions. In China, over 290 million people are affected by diabetic cardio‐cerebrovascular diseases. These diseases account for more than 40% of deaths and impose a significant economic burden on both society and families.
