To be able to evaluate new radiopharmaceuticals and optimize diagnostic and therapeutic procedures, relevant animal models are required. The aim of this study was to evaluate the medullary thyroid carcinoma GOT2 animal model by analyzing the biodistribution of 177Lu-octreotate and 111In-minigastrin (MG0). BALB/c nude mice, subcutaneously transplan...
در بخش اول پروژه تعدادی از داروها با- پلی (استایرن – مالئیک انیدرید) (psma) پیوند داده شد. گرافت دارو به psma با ترکیب گروه های انیدریدی موجود در psma با داروهای دارای گروه های عاملیsh ،oh ،nh و nh2با تشکیل تیامید استر یا آمید انجام می گیرد. پیوند کووالانسی داروها با psma با طیف بینی ir و uv-visشناسایی گردیده است. بررسی محلول هیدرولیز با طیف بینی uv نشان می دهد که آزادسازی دارو بوسیله هیدرولیز ...
Introduction: Somatostatin receptors expressed on a wide range of human tumors, are potential targets for the peptide receptor radionuclide therapy (PRRT). In this study, 177Lu-[DOTA-DPhe1, Tyr3]octreotide (177Lu-DOTATOC) as an agent for PRRT was prepared and its biodistribution was studied in rats. Methods: The best condition for the preparation of the 177Lu-DOTATOC radiolabeled complex was de...
BACKGROUND We herein report a comparison of the radiolabels 177Lu and 125I bound to the monoclonal antibody HH1 that targets the CD37 antigen expressed on non-Hodgkin B-cell lymphomas. MATERIALS AND METHODS Mixtures of 177Lu and 125I-labeled HH1 antibody were co-injected into nude mice carrying Ramos xenografts and the biodistribution using the paired label format allowing tracer comparisons ...
Prostate-specific membrane antigen (PSMA), a type II transmembrane glycoprotein, is overexpressed in prostate cancer. PSMA is a unique cell surface marker, negatively regulated by androgen and extensively used for imaging of hormone refractory carcinomas and metastatic foci. PSMA is a carboxypeptidase with two important enzymatic functions, namely, folate hydrolase and NAALADase. PSMA also exhi...
Background: Owing to its favourable decay characteristics 177Lu [T1/2= 6.71 d, Eβ(max)= 497 keV] is an attractive radionuclide for various therapeutic applications. Ethylene diamine tatramethylene phosphonate (EDTMP) is one of the most widely used ligands which form stable complexes with various radionuclides and all the complexes. Materials and Methods: Enriched 176Lu2O3 was dissolve...
Purpose: Based on the clinical relevance of the chemokine receptor 4 (CXCR4) as a molecular target in cancer and on the success of [68Ga]pentixafor as an imaging probe for high-contrast visualization of CXCR4-expression, the spectrum of clinical CXCR4-targeting was expanded towards peptide receptor radionuclide therapy (PRRT) by the development of [177Lu]pentixather. Experimental design: CXCR4 ...
