Sensing and Imaging Agents for Cyclooxygenase Enzyme

Area of Science:

• Biomedical Engineering
• Molecular Imaging
• Cancer Diagnostics

Background:

• Accurate targeting of cancer cells and intracellular activities is vital for early cancer diagnosis and treatment research.
• Cyclooxygenase-2 (COX-2) is a significant biomarker in cancer, particularly for identifying cancer stem cells and inflamed tissues.

Purpose of the Study:

• To develop and evaluate COX-2-specific fluorescent probes for enhanced cancer imaging and diagnosis.
• To investigate the potential of these probes for visualizing tumor and inflamed tissues with high selectivity.

Main Methods:

• Design and synthesis of fluorescent probes based on indomethacin (IMC), celecoxib, rofecoxib, and CoxFluor derivatives.
• In vitro and in vivo experiments utilizing mouse models and human tissue samples to assess probe performance.
• Evaluation of probe selectivity and fluorescence enhancement upon binding to COX-2 enzymes.

Main Results:

• Probes demonstrated high selectivity and specific fluorescence enhancement upon binding to COX-2.
• Successful visualization of tumor and inflamed tissues in both in vitro and in vivo models.
• Efficacy confirmed for detailed imaging in clinical and research applications.

Conclusions:

• COX-2-specific fluorescent probes represent a significant advancement in non-invasive cancer imaging and diagnosis.
• These probes facilitate precise visualization and monitoring of cancer-related activities.
• The developed probes hold great potential for improving early cancer detection and therapeutic strategies.
