Synthesis and Biological Evaluation of Novel Cationic Rhenium and Technetium-99m Complexes Bearing Quinazoline Derivative for Epidermal Growth Factor Receptor Targeting.

Epidermal growth factor receptor (EGFR) plays a vital role in cell proliferation and survival, with its overexpression linked to various malignancies, including non-small cell lung cancer (NSCLC). Although EGFR tyrosine kinase inhibitors (TKIs) are a key therapeutic strategy, acquired resistance and relapse remain challenges. This study aimed to synthesize and evaluate novel rhenium-based complexes incorporating EGFR TKIs to enhance anticancer efficacy, particularly in radiosensitization.

Synthesis and Evaluation of Tc(CO) Complexes with Ciprofloxacin Dithiocarbamate for Infection Imaging.

The accurate diagnosis of bacterial infections remains a critical challenge in clinical practice. Traditional imaging modalities like computed tomography (CT) and magnetic resonance imaging (MRI) often fail to distinguish bacterial infections from sterile inflammation. Nuclear medicine, such as technetium-99m (Tc) radiopharmaceuticals, offers a promising alternative due to its ideal characteristics.
