ABSTRACT

N-(2-Hydroxybenzyl)-2-amino-2-deoxy-D-glucose (NHADG) was synthesized by conjugation of salicylaldehyde to glucosamine. The obtained compound was well characterized via different analytical techniques. Labeling of the synthesized compound with technetium-99m ((99m)Tc) in pertechnetate form ((99m)Tc O4-) was carried out via chelation reaction in the presence of stannous chloride dihydrate. Maximum radiochemical yield of (99m)Tc-NHADG complex (99%) was obtained by using 1 mg NHADG, 200 μg SnCl2.2H2O, at pH 9.5 and reaction time of 15 min. The radiochemical purity of the (99m)Tc-NHADG complex was measured by instant thin layer chromatography (ITLC) and paper chromatography (PC), without any notable decomposition at room temperature over a period of 4h. The biological evaluation results show that the (99m)Tc labeled NHADG conjugate is able to specifically target mammary carcinoma in mice models, thus highlighting its potential as an effective (99m)Tc labeled glucose-derived agent for tumor imaging.
