Abstract
Abstract
Irbesartan was labeled using 125I or 131I with N-bromosuccinimide (NBS) as an oxidizing agent. A lot of operators such as, quantity of substrate, the quantity of oxidizing agent, reaction temperature, reaction time, and pH of reaction medium were studied to optimize high radiochemical yield of [125I]IodoIrbesartan ([125I]Irb.). The preclinical evaluation of IodoIrbesartan in experimental mice indicated high accumulation in target organ of heart with a high heart/blood ratio of 12.85 at 30 min post-injection. This study indicates the suitability of [125I]IodoIrbesartan ([125I]Irb.) for cardiac imaging.

Abstract
The purpose of this study was to determine the optimum conditions for labeling genistein compounds with technetium-99m (99mTc) radionuclides and the percentage of purity obtained in accordance with the requirements of the United State Pharmacopeia. The method used is optimization of several parameters including pH, SnCl2.2H2O as reducing agents, genistein concentration, and incubation time. The results showed that the optimum conditions for labeling 99mTc-Genistein were obtained under conditions of pH 8, the amount of SnCl2.2H2O reducing agents was 30 μg, 0.5 mg genistein, and in 10 min. The optimization of this condition resulted in radiochemical purity in the labeling of 99mTc-Genistein compounds at 95.43% ± 0.85%. The radiochemical purity of the labeling of 99mTc-Genistein compounds has met the requirements of the United State Pharmacopeia as a compound marked for diagnosis of more than 90%.

Abstract
Abstract
The present work has assessed the ability and competency of radioiodinated landiolol that is considered a potential cardio selective imaging agent. Landiolol was radiosynthesized with [131I] using chloramine-T (Ch-T) as an oxidizing agent. To give high radiochemical yield of the [131I]landiolol reaching values of 98% with high stability up to 48 h. The labeled compound was separated and purified using thin layer chromatography (TLC), paper electrophoresis and high performance liquid chromatography (HPLC). Biodistribution studies indicated that [131I]landiolol gave high heart uptake ratio of [45.0±0.19% ID/g at 2 min post injection (p.i.)]. Therefore, [131I]landiolol could be considered as a novel tracer to image heart with high heart/blood ratio within 60 min.

Abstract
PURPOSE Therapeutic agents used in chemotherapy have low specificity leading to undesired severe side effects. Hence, the development of drug delivery systems that improve drug specificity, such as liposome moieties, is an alternative to overcome chemotherapy limitations and increase antitumor efficacy. In this study, the biodistribution profile evaluation of pH-sensitive long-circulating liposomes (SpHL) containing [99mTc]DOX in 4T1 tumor-bearing BALB/c mice is described. PROCEDURES [99mTc]DOX was radiolabeled by direct method. Liposomes were prepared and characterized. [99mTc]DOX was encapsulated into liposomes by freezing and thawing. Circulation time for SpHL-[99mTc]DOX was determined by measuring the blood activity from healthy animals. Biodistribution studies were carried out in tumor-bearing mice at 1, 4, and 24 h after injection. RESULTS Blood levels of the SpHL-[99mTc]DOX declined in a biphasic manner, with an α half-life of 14.1 min and β half-life of 129.0 min. High uptake was achieved in the liver and spleen, due to the macrophages captured. Moreover, tumor uptake was higher than control tissue, resulting in high tumor-to-muscle ratios, indicating higher specificity for the tumor area. CONCLUSION [99mTc]DOX was successfully encapsulated in liposomes. Biodistribution indicated high tumor-to-muscle ratios in breast tumor-bearing BALB/c mice. In summary, these results showed the higher accumulation of SpHL-[99mTc]DOX in the tumor area, suggesting selective delivery of doxorubicin into tumor.

Abstract
We present the combination of the clinically well-proven chemotherapeutic agent, Doxorubicin, and (99m)Tc, an Auger and internal conversion electron emitter, into a dual-action agent for therapy. Chemical conjugation of Doxorubicin to (99m)Tc afforded a construct which autonomously ferries a radioactive payload into the cell nucleus. At this site, damage is exerted by dose deposition from Auger radiation. The (99m)Tc-conjugate exhibited a dose-dependent inhibition of survival in a selected panel of cancer cells and an in vivo study in healthy mice evidenced a biodistribution which is comparable to that of the parent drug. The homologous Rhenium conjugate was found to effectively bind to DNA, inhibited human Topoisomerase II, and exhibited cytotoxicity in vitro. The collective in vitro and in vivo data demonstrate that the presented metallo-conjugates closely mimic native Doxorubicin.
