Development and Biological Evaluation of the First Highly Potent and Specific Benzamide-Based Radiotracer [¹⁸F]BA3 for Imaging of Histone Deacetylases 1 and 2 in Brain

Pharmaceuticals, 2022
The degree of acetylation of lysine residues on histones influences the accessibility of DNA and, furthermore, the gene expression. Histone deacetylases (HDACs) are overexpressed in various tumour diseases, resulting in the interest in HDAC inhibitors ...

GMP‐compliant production, validation and dosimetry of clinical grade [18F]3‐(3‐fluoropropyl)‐2‐phenyl‐2,3‐dihydrobenzo[d]thiazole ([18F]FPBT) for oxidative stress PET imaging

British Journal of Pharmacology, EarlyView.
Background and Purpose Oxidative stress plays a critical role in the pathophysiology of various diseases, yet current methods for its non‐invasive detection remain limited. This study aimed to systematically validate a superoxide‐selective PET tracer, [18F]FPBT, for the early diagnosis and therapeutic monitoring of oxidative stress‐related conditions ...

Recent Developments in Carbon-11 Chemistry and Applications for First-In-Human PET Studies

Molecules, 2023
Positron emission tomography (PET) is a molecular imaging technique that makes use of radiolabelled molecules for in vivo evaluation. Carbon-11 is a frequently used radionuclide for the labelling of small molecule PET tracers and can be incorporated into

Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

Medicinal Research Reviews, Volume 46, Issue 5, Page 1362-1389, September 2026.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...

Sugar Amino Acid Linkers for the Design of [18F]SiFA‐PSMA Radioligands

ChemMedChem, Volume 21, Issue 15, 14 August 2026.
Sugar amino acid (SAA) linkers were incorporated into silicon‐fluoride‐acceptor (SiFA)‐prostate‐specific membrane antigen (PSMA) radioligands to modulate pharmacokinetic properties while preserving efficient 18F isotopic exchange radiolabeling. Furanose‐based SAAs outperformed pyranose analogues, enabling specific tumor visualization by PET despite ...

Affinity‐Tuned Albumin Hitchhiking Extends the Bioorthogonal Capture Window in Pretargeting Radiotheranostics

Advanced Healthcare Materials, Volume 15, Issue 29, 7 August 2026.
Pharmacokinetic engineering of clickable radioligands was achieved via albumin hitchhiking approach within a pretargeted radiotheranostics delivery platform. This approach reduced rapid renal elimination, expanded bioorthogonal capture window, boosted tumor uptake by ∼3.5‐fold, and improved the tumor‐to‐liver ratio by ∼6‐fold.

Myocardial Lipid Metabolism Imbalance: The Pathological Core and Novel Diagnostic‐Therapeutic Directions of Cardiovascular Diseases

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
In cardiac cells, Plin5/AMPK regulate lipid homeostasis; excess CD36‐mediated uptake drives lipotoxicity, mitochondrial dysfunction, and CVDs (e.g., heart failure). Biomarkers (ApoB/ApoA‐1) and therapies (SGLT2 inhibitors) target this cascade. ABSTRACT Cardiac lipid metabolism is fundamental to myocardial energy homeostasis, with fatty acid oxidation ...

Lymphatic Drainage of Cerebrospinal Fluid Using Lymph Node Seeker 64Cu‐Labeled Gram‐Negative Bacterial Extracellular Vesicles With Positron Emission Tomography (PET)

Journal of Extracellular Vesicles, Volume 15, Issue 8, August 2026.
ABSTRACT Cerebrospinal fluid (CSF) is drained into the systemic lymphatics via paravertebral lymph nodes. Superficial and deep cervical lymph nodes collect CSF in mice, but the exact and quantified routes are unknown. Recently, we simultaneously visualized cervical, sacral and iliac lymph nodes via serial imaging on the intrathecal [64Cu]Cu‐albumin ...

Quantitative Imaging of Pyruvate Metabolism in a Patient With Anaplastic Thyroid Cancer

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 826-838, August 2026.
ABSTRACT Purpose Magnetic resonance imaging using hyperpolarized (HP) [1‐13C]‐pyruvate enables assessment of pyruvate metabolism in vivo and offers new insight into metabolic changes in response to cancer therapy. Widely used semi‐quantitative metrics of pyruvate metabolism can be affected by physiological factors that are extrinsic to intracellular ...
