Structure‐Based Design, Synthesis, and Evaluation of Novel Ponatinib Derivatives With a Significantly Altered Selectivity Profile

ChemMedChem, Volume 21, Issue 11, 15 June 2026.
We developed new derivatives of the cancer drug ponatinib, significantly reducing and altering its spectrum of target kinases. Compound 5 retained the efficacy in inhibiting the colony formation of MDA‐MB‐231 cells and acted primarily on B‐Raf and Flt‐1 as its main targets in a kinase panel.

Revisiting Hydrazine Moiety as a Scaffold for the Synthesis of Potential Antiviral Pyrazole Ribonucleoside Analogues

ChemMedChem, Volume 21, Issue 11, 15 June 2026.
Three series of pyrazole ribonucleoside analogues were designed and synthesized. They were evaluated, along with some of their pronucleotides, for their antiviral activity against RNA viruses. Pyrazole ribonucleoside analogues were prepared via a linear approach starting with the reaction of D‐ribosylhydrazine with 1,3‐dicarbonyl or acrylonitrile ...

Probing 3‐Amino‐2H‐Azaindazoles as Allosteric Inhibitors of the Protein Tyrosine Phosphatase SHP2

ChemMedChem, Volume 21, Issue 11, 15 June 2026.
A palladium‐catalyzed domino reaction facilitated the discovery and rapid synthesis of selective, potent 3‐amino‐2H‐azaindazole derivatives serving as allosteric inhibitors of SHP2. Structural analysis via co‐crystallography confirmed binding at the allosteric site, thereby stabilizing the autoinhibited SHP2 conformation, qualifying this scaffold as a ...

Synthesis and Evaluation of Novel Cinnamic Acid Hybrids With Antiacetylcholinesterase, Antioxidant, and Anti‐Inflammatory Properties

ChemMedChem, Volume 21, Issue 11, 15 June 2026.
In this work, we identified two novel pleiotropic sinapic acid derivatives with excellent anti‐acetylcholinesterase, antioxidant, and anti‐inflammatory properties. Alzheimer's disease, one of the most widespread neurodegenerative disorders, is known for its multifactorial nature that makes it challenging to treat.

Photocatalytic Vanadium‐Mediated Amination of Benzene With Hydroxylamine

Chemistry – A European Journal, Volume 32, Issue 22, 9 June 2026.
Photochemical activation of N‐phenylphenothiazine (PPT) enables a selective direct benzene amination with hydroxylamine in the presence of various vanadium catalysts under mild reaction conditions. Spectroscopic and kinetic analyses identify a key vanadium(IV)‐hydroxylamine intermediate, elucidate the crucial roles of the acidic medium, the ...

N‐Amidinyl‐Benzodiazaborines as Novel Boron‐Based Scaffolds: Synthesis and Application in Retromer Stabilization

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
In this work, we successfully synthesized a library of novel N‐amidinyl‐benzodiazaborines, showing how these heteroaryl guanyl hydrazones are able to stabilize the retromer, a protein complex involved in the disposal of misfolded and aggregated proteins, whose malfunction is observed in multiple neurodegenerative diseases.

Enhanced Li‐Ion Battery Performance with Hybrid MXene/GnR Electrodes: Heterojunctions and Engineered Architectures Supported by DFT Mechanistic Studies for Improved Rate Performance, Stability & Capacity

Advanced Functional Materials, Volume 36, Issue 46, 8 June 2026.
Lithium‐ion batteries (LIBs) remain central to energy storage but suffer from slow ion transport and degradation. Here, we present a binder‐free Ti3C2Tx MXene/GnR hybrid electrode with a porous 3D architecture formed via freeze casting. The structure enhances conductivity, ion transport, and stability, delivering 401 mAh/g, ∼97% efficiency, and 92 ...
