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 ...

Theranostic π Electron‐Stabilized Polymeric Micelles for PET Imaging‐Guided Drug Delivery to Tumors

Small, Volume 22, Issue 49, 1 September 2026.
Cancer nanomedicine efficacy is limited by heterogeneous nanoparticle accumulation in tumors. Nuclear imaging offers non‐invasive, patient‐ and lesion‐specific visualization and quantification of nanoparticle uptake. We present a positron emission tomography (PET)‐imageable micelle platform for direct quantification of nanoparticle accumulation and ...

Radiosynthesis and Biological Evaluation of [18F]R91150, a Selective 5-HT2A Receptor Antagonist for PET-Imaging

, 2021
Serotonergic 5-HT2A receptors in cortical and forebrain regions are an important substrate for the neuromodulatory actions of serotonin in the brain. They have been implicated in the etiology of many neuropsychiatric disorders and serve as a target for ...

Increased Binding of [18F]Nifene, a PET Imaging Probe for α4β2* Nicotinic Acetylcholinergic Receptors in Hippocampus–Subiculum of Postmortem Human Parkinson's Disease Brain

Synapse, Volume 80, Issue 5, September 2026.
[18F]Nifene, a PET imaging probe for α4β2* nicotinic acetylcholine receptors, was used to discretely measure changes in hippocampus (HP) and subiculum (SUB) of postmortem Parkinson's disease (PD) cases compared to cognitively normal (CN) cases. Significant increased [18F]nifene binding in PD was observed.
