Synthesis, radiolabeling and in vitro evaluation of azathioprine loaded magnetic solid lipid nanoparticles
In this study, it is aimed to design a smart drug delivery system for the diagnosis and treatment of cancer cells. Magnetic-solid lipid nanoparticles were synthesized as a drug delivery system and azathioprine (AZA) was loaded into this system. This newly created system was radiolabeled using technetium-99 m with a radiolabeling yield of 90.3%. Drug loading into the SLMNP was found as 86%. The biological behavior of Tc-99m and radiolabeled magnetic solid lipid nanoparticles loaded with azathioprine (Tc-99m-AZA-SLMNP) was investigated in vitro and in vivo.Ege University (Izmir-Turkey) [22153]; Ege University (Izmir-Turkey) [22153]This study was financialy supported by Ege University Scientific Research Project numbered 22153 (Izmir-Turkey)
Radiosynthesis and biodistribution of 99mTc-Sulfamethoxazole: a novel molecule for in-vivo infection imaging
The aim of this study was to prepare 99mTc-Sulfamethoxazole complex and evaluate its efficiency as an infection imaging agent. The Sulfamethoxazole was labeled with 99mTc and its biological efficacy as a potential radio tracer for Staphylococcus aureus infection was investigated in bacterially infected Albino Wistar rats. The radiolabeling yield was found to be 95 ± 3.07% and remained constant at more than 93 ± 0.1% even in serum for 240 min after radiolabeling. 99mTc-Sulfamethoxazole prepared with high yield localized well in the bacterially infected muscle of the rats. 99mTc-Sulfamethoxazole may be developed as a radiopharmaceutical agent to distinguish infection from inflammation by nuclear imaging. © 2017, Springer Science+Business Media, LLC
