Rhemium-186-1-hydroxyethylidene-1,1-diphosphonate ((186)Re-HEDP) has been used for the palliation of metastatic bone pain. However, delayed blood clearance and high gastric uptake of radioactivity have been observed upon injection, due to the instability of (186)Re-HEDP. We designed, synthesized and evaluated a stable (186)Re-mercaptoacetylglycylglycylglycine (MAG3) complex-conjugated bisphosph...
We have evaluated the potential of 188Re-labeled monoclonal antibodies (MAbs) modified with 2-iminothiolane (2IT) for targeting small-cell lung cancer (SCLC). Radiolabeled MAbs NK1NBL1 and C218 recognizing neural cell adhesion molecule were injected i.v. into athymic mice inoculated with human SCLC tumors, and the biodistribution was examined. NK1NBL1 localized in the tumors better than C218. 1...
Rhenium-188, obtained from an alumina-based tungsten-188/rhenium-188 generator, is actually considered a useful candidate for labeling biomolecules such as antibodies, antibody fragments, peptides, and DNAs for radiotherapy. There is a widespread interest in the availability of labeling procedures that allow obtaining 188Re-labeled radiopharmaceuticals for various therapeutic applications, in p...
Nanoliposomes are useful carriers in drug delivery. Radiolabeled nanoliposomes have potential applications in radiotherapy and diagnostic imaging. In this study, the biodistribution and pharmacokinetics of 188Re-BMEDA-labelled pegylated liposomes (RBLPL) and unencapsulated 188Re-BMEDA administered by the i.v. route in murine C26-colon tumour-bearing mice were investigated. MicroSPECT/CT images ...
OBJECTIVE Metastasis of the osseous tissue is one of the frequent and severe aggravations as a result of several neoplastic conditions, such as metabolic disorders, infections, and cancer. The objective of this study was to evaluate the pertinence of [68Ga]-trans-1,2-cyclohexyldinitrilo tetramethylene phosphonic acid (CDTMP) as a potential bone imaging agent for positron emission tomography (PE...
UNLABELLED This retrospective study compared the effects of single and multiple administrations of (186)Re-hydroxyethylidenediphosphonate ((186)Re-HEDP) on palliation and survival of prostate cancer patients presenting with more than 5 skeletal metastases. METHODS A total of 60 patients were divided into 3 groups. Group A (n = 19) consisted of patients who had received a single injection; gro...
Thirty patients had bone scintigraphy with both Tc-99m pyrophosphate (Tc-PPi) and Tc-99m diphosphonate (Tc-HEDP). The images were given a composite rating for quality and the basis of three sets of criteria, and were also compared for the number of lesions detected by each agent. The two agents provided no difference in scan quality. Nevertheless, in ten of the 30 patients, at least two of the ...
رادیوداروهای تشخیصی 99mTc-MDP و 99mTc-HEDP بیش از سه دهه است که برای سنتیگرافی استخوان بکار میروند. هدف از اجرای این کار پژوهشی سنتز بیفسفونات HEDP در بخش تهیه و تولید رادیوایزوتوپ است که بعنوان ماده اولیه برای تولید کیت لیوفیلیزه HEDP بصورت استریل و بدون مواد تبزا میباشد. نتایج حاصل نشان میدهند که ماده سنتز شده HEDP بیش از 95 درصد قابلیت نشاندارشدن با رادیوداروی پرتک...
UNLABELLED Twenty-eight patients (12 men with prostate cancer, 16 women with breast cancer) were included in a phase II trial to evaluate the efficacy of 186Re-hydroxyethylidene diphosphonate (HEDP) on pain from bone metastasis and the toxicity of this agent. METHODS After intravenous administration of 1295 MBq 186Re-HEDP, the efficacy was evaluated by means of a daily log. RESULTS We obser...
In this work, a bio-based flame retardant (Cy-HEDP) was synthesized from cytosine and HEDP through facile salt-forming reaction embedded into epoxy matrix to improve the retardancy smoke suppression performance. The product Cy-HEDP well characterized by FTIR, 1 H 31P NMR SEM tests. On basis of results, adding 15 wt% Cy-HEDP, EP15 can pass UL-94 V-0 rating, total production (TSP) as heat release...
