One‐Step Access to Ultra‐Bright Macrocyclic Oligo‐BODIPYs Featuring Long‐Lived Cyclic Excitons

Angewandte Chemie, EarlyView.
Strong Fluorescence Meets Long Lifetimes: A template‐free, one‐step synthesis affords a series of methylene‐bridged macrocyclic oligo‐BODIPYs combining strong fluorescence with exceptionally long fluorescence lifetimes. Steady‐state and time‐resolved optical spectroscopy reveal unique excitonic coupling conditions and unusual size‐dependent ...

To Greater Twist: A Kinetically Biased π‐Radical Cascade

Angewandte Chemie, EarlyView.
π‐Radical cascades enable step‐economic construction of complex polycyclic aromatic frameworks. In this work, we show that a multifurcating pathway can be kinetically steered toward a single, more distorted product. This counterintuitive “falling‐upward” outcome arises from an intrinsic mechanistic bias, revealing a broader dimension of control in π ...

A DNA G‐Quadruplex‐Targeting Ligand Suppresses c‐MYC Expression: Implications for Gemcitabine‑Resistant Pancreatic Cancer

Angewandte Chemie, EarlyView.
PQB‐4, a fluorescent small‐molecule ligand that targets c‐MYC DNA G‐quadruplexes (G4s), showed marked synergy with gemcitabine in resistant PANC‐1 cells (CI = 0.027). In vivo, the ligand reduced tumor weight by 44% in a PANC‐1 xenograft model. These results highlight the therapeutic potential of c‐MYC DNA G4‐targeting ligands for treating gemcitabine ...
