Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

Chelation‐Assisted Metal‐Catalyzed Ligation and Cleavage Reactions for Chemical Biology

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Chelation‐assisted transition metal catalysis has emerged as a promising complement to bioorthogonal click chemistry for studying biological processes. By pre‐organizing catalytic metal centers, designed coordinating substrates enhance reactivity and biocompatibility, enabling site‐selective ligation and decaging reactions in complex biological media ...

Selective N‐Functionalization of Pyrazoles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

Click Bioconjugation of Aza‐BODIPY Fluorophores to LfcinB Peptides for Improved Biocompatibility

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Click bioconjugation attaches NIR aza‐BODIPY fluorophores to LfcinB‐derived anticancer peptides via CuAAC and thiol‐maleimide chemistry. Conjugates exhibit improved predicted solubility while retaining strong NIR absorption (703–730 nm). Peptide‐aza‐BODIPY conjugates induce apoptotic morphology in HeLa cancer cells.

Recent advances and prospects for high‐efficiency blue hot exciton organic light‐emitting diodes

open access: yesFlexMat, EarlyView.
Blue organic light‐emitting diodes (OLEDs) face great challenges in achieving the balance between color purity, device efficiency, and stability. Hot exciton materials offer a solution by rapidly converting non‐emissive triplet excitons into singlet ones through a high‐lying reverse intersystem crossing process.

Cysteine Peptidases in Antitumor Immunity: Unraveling Antigen‐Presenting Cell Regulation and Therapeutic Potential

open access: yesiMetaMed, EarlyView.
This review systematically summarizes the central role of cysteine peptidases in modulating antigen‐presenting cell (APC) function and antitumor immune responses, highlighting their critical significance in overcoming tumor immune evasion. Current research has established that cysteine peptidase subtypes, including cathepsins B, S, L, and X, exert ...
