τBu₂SiF-Derivatized D₂-Receptor Ligands: The First SiFA-Containing Small Molecule Radiotracers for Target-Specific PET-Imaging [PDF]

open access: yes, 2011
The synthesis, radiolabeling and in vitro evaluation of new silicon-fluoride acceptor (SiFA) derivatized D-2-receptor ligands is reported. The SiFA-technology simplifies the introduction of fluorine-18 into target specific biomolecules for Positron ...

A minimal physiologically‐based pharmacokinetic modeling platform to predict intratumor exposure and receptor occupancy of an anti‐LAG‐3 monoclonal antibody

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 460-473, March 2025.
Abstract In oncology drug development, measuring drug concentrations at the tumor site and at the targeted receptor remains an ongoing challenge. Positron emission tomography (PET)‐imaging is a promising noninvasive method to quantify intratumor exposure of a radiolabeled drug (biodistribution data) and target saturation by treatment doses in vivo ...

2D van der Waals System Integrated with Targeting Radio‐Diagnostic and Imaging Functions

open access: yesSmall, EarlyView.
Layered double hydroxide (LDH) nanoplates were engineered for tumor‐targeted imaging and therapy. By exploiting folate receptor (FR) expression levels, the system achieves selective tumor accumulation and high‐resolution dual PET/fluorescence (PET/FL) imaging.

A new method for radiolabeling of human immunoglobulin-G and its biological evaluation

open access: yesJournal of Pharmacy and Bioallied Sciences, 2012
Background: Radiolabeled human Immunoglobulin-G (hIgG) has demonstrated its utility in inflammation and infection imaging. However, the present method of radiolabeling hIgG is time-consuming and complex.

Competitive SELEX Strategy for High‐Affinity Aptamer Isolation and Enhanced Biosensing

open access: yesSmall, EarlyView.
A novel competitive SELEX strategy was developed to isolate high‐affinity aptamers by using a lower‐affinity competitor during the selection process. This approach enabled the identification of an aptamer with exceptional binding affinity, significantly improving target detection sensitivity.

X-ray Structures of Succinimidyl Halobenzoates

open access: yesCrystals, 2017
The crystal and molecular structures of five succinimidyl halobenzoates are reported. Corresponding derivatives with the respective halo-radionuclide (18F, 76Br, 123I/124I/125I/131I) were prepared and used for the radiolabeling of biologically active ...

Rational design of a lipophilic β‐galactosidase‐responsive near‐infrared probe for in vivo imaging of cellular senescence

open access: yesSmart Molecules, EarlyView.
We developed a lipophilic near‑infrared probe (DCIP‑AcGal) that is specifically activated by senescence‑associated β‑galactosidase. After intravenous injection, it lights up therapy‑induced tumor senescence in living mice. Its optimized lipophilicity also enables blood‑brain barrier crossing to detect natural brain senescence ex vivo. This probe offers

Nanobodies as next‐generation targeting platforms: From discovery technologies to translational biomedicine

open access: yesVIEW, EarlyView.
Nanobodies, derived from the variable domains of camelid heavy‐chain‐only antibodies, have emerged as transformative biomedical tools due to their nanoscale size, exceptional stability, and unique capacity to recognize cryptic epitopes. This review provides a comprehensive overview of the field, outlining the structural and biochemical features of ...

Nanomedicine applications in lymphoma: Advancing precision diagnostics, targeted therapeutics, and prospective developments

open access: yesVIEW, EarlyView.
Lymphoma is a group of blood cancers that can appear in lymph nodes, blood, bone marrow, spleen, liver, or the central nervous system, which makes drug delivery and disease monitoring difficult. This review summarizes how nanomedicine technologies may improve targeted treatment and imaging, while carefully separating approved or guideline‐supported ...

Evidence That the Protein Phosphatase Activity of PTEN Contributes to Embryonic Development and Tumor Suppression

open access: yesCancer Science, EarlyView.
Mice expressing only mutant PTEN Y138L, a protein which shows normal suppression of cellular AKT yet lacks protein phosphatase activity, die in utero, and heterozygous mice display a range of tumors. This indicates both the lipid and protein phosphatase activities of PTEN work together for normal tumor suppression and embryonic development.
