Complexion of Boric Acid with 2-Deoxy-D-glucose (DG) as a novel boron carrier for BNCT

Abstract

Objective: Boron neutron capture therapy (BNCT) is an intensive research area for cancer researchers. Especially the side effects and inabilities of conventional therapies in some cases, directs researchers to find out a new cancer therapy methods such as BNCT. One of three important problem of BNCT is targeting of boron to tumor tissue. Borono Phenyl Alanine (BPA) and Borono Sodium Borocaptate (BSH) are already using in clinical studies as boron carriers. New boron carriers are searching for high yield boron accumulation in the tumor tissue. Methods: In this study, a novel 10B carrier was synthesized, ((2R)-4,5,6-trihydroxy-2-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)boronic acid ( 10B-DG), for BNCT studies. 10Boric Acid and 2-Deoxy-d-Glucose was complexed ( 10B-DG) through a low-high pH reaction and yield of complexion was tested with FTIR ATR and Liquid Chromatography Mass Spectrometry (LC/MS). Results: Confirmation studies have been carried out by HPLC and chromatograms have confirmed that Borono-2-Deoxy-d-Glucose synthesized with % 80 yield. Conclusions: This compound appears to be an alternative boron carrier for BNCT applications
