Boron Drug Delivery via Encapsulated Magnetic Nanocomposites : A New Approach for BNCT in Cancer Treatment

Abstract EN

Ortho-carborane cages have been successfully attached to modified magnetic nanoparticles via catalytic azide-alkyne cycloadditions between 1-R-2-butyl-Ortho-C2B10H10(R=Me,3;Ph,4) and propargyl group-enriched magnetic nanoparticles.

A loading amount of 9.83 mmol boron atom/g starch-matrixed magnetic nanoparticles has been reached.

The resulting nanocomposites have been found to be highly tumor-targeted vehicles under the influence of an external magnetic field (1.14T), yielding a high boron concentration of 51.4 μg/g tumor and ratios of around 10 : 1 tumor to normal tissues.
