Fluorescein-Tagged 1Methyl-o-carborane A Promising Agent for Boron Neutron Capture Therapy

Introduction

Boron Neutron Capture Therapy (BNCT) has gained significant attention as a targeted cancer treatment strategy due to its ability to selectively destroy tumor cells while sparing healthy tissues. A recent study explored the synthesis and biological evaluation of a fluorescein-tagged 1-methyl-o-carborane bioconjugate, aiming to enhance delivery and monitoring in BNCT. The compound demonstrated higher boron content and moderate cytotoxicity compared to traditional boron delivery agents like sodium borocaptate (BSH) and boronophenylalanine (BPA).

Key Findings from the Study

• Novel Synthesis Approach: Researchers conjugated fluorescein with 1-methyl-o-carborane through a Williamson ether synthesis reaction.
• Improved Boron Delivery: The new conjugate offers higher boron content compared to existing clinical agents BSH and BPA.
• Biological Evaluation:
  • In squamous cell carcinoma (SCC-VII), the conjugate showed moderate cytotoxicity (IC50 ≈ 1 mM), making it less toxic than traditional agents.
  • In pancreatic cancer cells (MIA PaCa-2), flow cytometry and fluorescent imaging confirmed efficient uptake and uniform intracellular distribution.
• Potential Theranostic Use: Fluorescein labeling enabled real-time tracking under fluorescence microscopy, highlighting diagnostic and therapeutic potential.
