AB  - The extensive development of radiopharmaceuticals towards early tumour detection and treatment has increased the demand for new ligands with higher tumour selectivity. Research has been done on the potential of the novel O,O-diethylethylenediamine-N,N-di-3-propanoate (L) ligand as a radionuclide vehicle for tumour targeting. Under alkaline conditions, L hydrolyses and produces half ester ligand (L) and diacid ligand (L), with characteristic donor atom array N, N, O. Ligand L was successfully labelled with Tc-99m at pH=9 by coordination with the octahedral fac-[Tc-99m(CO)(3)(H2O)(3)](+) intermediate, forming the main radioproduct fac-[(TcL)-Tc-99m(CO)(3)] (Tc1). The Tc-99m complex showed a low lipophilic character (log P = 0.48) and low binding affinity to human serum albumin (2.51 +/- 0.48%). In vitro stability studies in saline and human plasma, as well as challenge studies with cysteine and histidine, revealed high stability of the complex during 24 h. Biodistribution studies of Tc1 in female C57BL/6 mice bearing B16/F1 melanoma metastases showed significant tumour uptake: 9.81 +/- 1.19% ID g(-1) in the liver, 5.87 +/- 0.54% ID g(-1) in the lungs and 3.17 +/- 0.33% ID g(-1) in the ovary at 30 min post-injection. Favourable physicochemical properties, satisfactory in vitro/in vivo stability and biodistribution profile in the experimental metastatic melanoma model indicate the possible application of the radiolabelled ligand in tumour diagnosis.

AB  - Two different types of magnetic nanoparticles (MNPs) were synthesized in order to compare their efficiency as radioactive vectors, Fe3O4-Naked (80 +/- 5 nm) and polyethylene glycol 600 diacid functionalized Fe3O4 (Fe3O4-PEG600) MNPs (46 +/- 0.6 nm). They were characterized based on the external morphology, size distribution, and colloidal and magnetic properties. The obtained specific power absorption value for Fe3O4-PEG600 MNPs was 200 W/g, indicated their potential in hyperthermia based cancer treatments. The labeling yield, in vitro stability and in vivo biodistribution profile of Y-90-MNPs were compared. Both types of MNPs were Y-90-labeled in reproducible high yield ( GT 97%). The stability of the obtained radioactive nanoparticles was evaluated in saline and human serum media in order to optimize the formulations for in vivo use. The biodistribution in Wistar rats showed different pharmacokinetic behaviors of nanoparticles: a large fraction of both injected MNPs ended in the liver (14.58%ID/g for Y-90-Fe3O4-Naked MNPs and 19.61%ID/g for Y-90-Fe3O4-PEG600 MNPs) whereas minor fractions attained in other organs. The main difference between the two types of MNPs was the higher accumulation of Y-90-Fe3O4-Naked MNPs in the lungs (12.14%ID/g vs. 2.00%ID/g for Y-90-Fe3O4-PEG600 MNPs) due to their in vivo agglomeration. The studied radiolabeled magnetic complexes such as Y-90-Fe3O4-PEG600 MNPs constitute a great promise for multiple diagnostic-therapeutic uses combining, for example, MRI-magnetic hyperthermia and regional radiotherapy.

AB  - The diimine dioxime ligand, 3,3-(1,4-butanediyl-dinitrilo)bis-2-pentanone, 2,2-dioxime (LH2), containing a N-4 donor set was prepared by the Schiff base condensation of 2-hydroxyimino-3-pentanone and 1,4-diaminobutane in two ways: in a protic and in an aprotic solvent. A higher yield of the (LH2) imine was obtained when the synthesis was performed using a protic solvent (C2H5OH) instead of aprotic benzene (78 and 30 %, respectively). The Cu(II) metal complex of diimine dioxime was synthesized in CH3OH from the perchlorate salt of LH2 in a 1:1 mole ratio. The isolated complex was characterized by the elemental analysis, IR spectroscopy and cyclic voltammetry. The structure of [Cu-2(LH)(2)](ClO4)(2) was determined by single-crystal X-ray diffraction analysis. Comparison with structurally related diimine dioxime Cu(II) complexes revealed the influence of a weak Cu center dot center dot center dot O(perchlorate) interaction on the geometry of the metallocycle.

AB  - Two novel diamine dioxime ligands, 4,7-diaza-3,8-diethyldecane-2,9-dione bis oxime (3) and 4,9-diaza-3,10-diethyldodecane-2,11-dione bis oxime (5), were synthesized in order to develop new brain perfusion imaging agents, based on 99mTc(V)-complexes. The synthesis involved condensation of 2-hydroxyimino-3-pentanone with appropriate diamine in protic solvent which afforded the bis imine adducts. Subsequent reduction of imine functional groups yielded a diastereoisomeric mixture of 3 and 5. UVvisible, IR, 1H NMR, 13C NMR and elemental analysis were used to characterize the structures of the synthesized compounds. 99mTc-complexes of both diamine dioximes were prepared and radiolabeling conditions optimized to give the maximum yield. Physicochemical parameters of the labeled complexes as well as and their biodistribution in rats were investigated. Both compounds (3 and 5) formed 99mTc-complexes with a net charge of zero, determined by electrophoresis. The resultant lipophilic 99mTc-complexes of 3 and 5 were readily formed at pH similar to 9.0 within 10?min at room temperature with yields of 90% and 95%, respectively. The 99mTc-3 complex was found to be stable within 1 similar to h, while 99mTc-5 was stable for a few hours. A significant brain uptake of 99mTc-3 (2.1% injected dose) and 99mTc-5 (1.8% injected dose) complexes, 2?min after injection, is in accordance with their lipophilicity. The present study suggests that both ligands are promising candidates as new 99mTc-based brain-imaging agents. Copyright (c) 2012 John Wiley and Sons, Ltd.

99mTc(V) complexes. The 99mTc(V)-d,l-HMPAO complex is well-known
radiopharmaceutical for brain imaging. The structures of the synthesized
compound were characterized by UV-Vis, IR, 1
H NMR and 13C NMR. The
procedure for radiolabeling of diamine-dioxime with 99mTc was developed and
radiolabeling yield of the 99mTc-complex was followed by paper and thin-layer
chromatography. The maximum radiolabeling yield was obtained when the
reactions were carried out at pH~9 within 10 min at room temperature (RT).
Biodistribution studies on rats has shown significant uptake of 99mTc-complex
(2.1% ID), 2 min after injection.

AB  - In this study, tin fluoride colloid (SnF-c) was prepared, labeled with yttrium-90 (90Y), and characterized with respect to its physicochemical properties and biological behavior in an animal model. Particle size of SnF-c, at constant concentration of SnF2, was dependent on pH, concentration of sodium fluoride (NaF), temperature, and time. The particle size of SnF-c decreased with an increase in NaF concentration and a decrease in reaction mixture pH. Radiolabeling yield of 90YSnF-c at higher temperature increased and it was greater than 98% for the preparation at 95 degrees C. The 90YSnF-c demonstrated high in vitro stability both in human serum and human synovial fluid at 37 degrees C up to 7 days. In vivo distribution studies in healthy male Wistar rats of 90YSnF-c (particles LT 1 mu m), following intravenous administration, revealed that the localization takes place preferably in the liver. The 90YSnF-c (particles GT 1 mu m) was well retained in the synovial space for 96 h after intra-articular injection, whereas leakage of 90Y from the joint was 1.96% over this period. Because of high labeling yield and stability, 90YSnF-c might be a promising agent for radiosynovectomy or therapy of liver malignancies.

AB  - Radiopharmaceuticals based on Y-90 are widely used in the treatment of malignant deseases. In order to meet the requirements for their future application, a Sr-90/Y-90 generator was developed and 90Y eluted from this locally produced generator was used for the radiolabelling of the DOTA-conjugated somatostatin analog [DOTA(0),Tyr(3)] octreotate and the preparation of [Y-90-DOTA(0),Tyr(3)] octreotate (Y-90-DOTATATE) for peptide receptore radionuclide therapy. Sr-90/Y-90 generator was based on the electrochemical separation of Y-90 from Sr-90 in a two-cycle electrolysis procedure. Three electrode cells were used to perform both electrolyses. In both cycles, working electrodes were kept on constant potential. The pH of the solution was adjusted to 2.7 of the value before the electrolyses. The radionucliclic purity of the Y-90 solution was analysed by ITLC and extraction paper chromatography. The labelling of peptide (100 mu g DOTATATE) with (YCl3)-Y-90 was performed at 95 degrees C for 30 minutes. Radiochemical purity was determined by HPLC and chromatographic separation, using a solid SepPak C-18 column. Results obtained confirmed the efficiency of our electrochemical separation technique and quality control methods for Y-90. The achieved efficiency of the Sr-90/Y-90 generator above 96% of the theoretical value represents a good basis for the further development of this generator. The labelling of the DOTATATE with Y-90 exhibited a high efficiency, too: there was less than 1% of Y-90(3+) in the Y-90-DOTATATE.

AB  - The 99mTc-labeling of baclofen (Bac), a muscle relaxant, as well as
physicochemical properties of the labeled compounds are investigated. Two
different approaches for the labeling with 99mTc have been studied: direct reduction
with tin(II)chloride and the 'organometallic approach' using [99mTc(CO)3(H2O)3]
+
precursor. The direct labeling approach was not successful and the yield was poor.
The use of [99mTc(CO)3(H2O)3]+ precursor pointed at the formation of 99mTc(I)
coordinated complexes with high yield. In this approach, pH didn’t influence the
yields. Promising results of in vitro experiments suggest that 99mTc(I)-baclofen may
be of potential use for diagnosis of some central nervous system disorders.

AB  - Radio labeled albumin microspheres with encapsulated citric acid-coated magnetite nanoparticles were developed as a targeting approach to localize both radioactivity and magnetic energy at the tumor site. We present in vitro and in vivo studies of yttrium-90 (Y-90)-labeled human scrum albumin magnetic microspheres (HSAMMS) as a multifunctional agent for possible applications in a bimodal radionuclide-hyperthermia cancer therapy. The HSAMMS were produced using a modified emulsification-heat stabilization technique and contained 11 nm magnetite nanoparticles coated with citric acid, distributed as inhomogeneous clusters within the albumin microspheres. The size, size distribution and the morphology of magnetite nanoparticles and HSAMMS were determined by FESEM, HRTEM and SEM/FIB dual beam. The average particle size of the complete HSAMMS was 20 mu m, and they exhibited superparamagnetic behavior at room temperature. The in vitro experiments (in saline and human serum) revealed the high stability of the labeled HSAMMS in saline and human serum after 72 h. Following the intravenous administration of the Y-90-HSAMMS in rats, 88.81% of the activity localizes in the lungs after 1 h, with 82.67% remaining after 72 h. These data on Y-90-HSAMMS provide good evidence for their potential use in bimodal radionuclide-hyperthermia cancer therapy.

AB  - Two rhenium(I) tricarbonyl complexes with the tridentate monoanionic NSO ligands, 4-(benzimidazol-2-yl)-3-thiabutanoic acid (complex 3) and [1-(11-carboxyundecanyl)-4-(benzimidazol-2-yl)]-3-thiabutanoic acid (complex 4) were synthesized and characterized by spectroscopic methods and elemental analysis. X-ray crystallographic analysis of complex 3 revealed a distorted octahedral geometry around rhenium defined by the three facially bound CO groups and the NSO donor atom set of the tridentate ligand. The analogous technetium-99m complexes (complexes 5 and 6) were also prepared quantitatively by reaction of the NSO ligands with the fac-[Tc-99m(H2O)(3)(CO)(3)](+) synthon and their identity was established by chromatographic comparison to their rhenium congeners. Biodistribution in mice of complex 6 bearing the fatty acid chain showed significant heart uptake (6.26 +/- 0.79% ID/g p.i.) at 1 min accompanied, however, with a heart: blood ratio below 1.

AB  - This paper reports synthesis of a new diaminodioxime ligand, derivative of
hexamethylpropyleneamine oxime (HM-PAO). The 99mTc(V)-d,l-HM-PAO
complex is well-known radiopharmaceutical for regional blood flow imaging. The
structure of the new ligand was investigated by elemental analysis, IR, 1H and 13C
NMR. Complexation studies with 99mTc were carried out using stannous chloride as
the reducing agent. The complex was characterized by paper chromatography and
thin-layer chromatography. It was obtained in high yield when the reactions were
carried out at pH=9. Also, it was found that the complex was stable up to 4 h.

AB  - In this paper the results of a stability of [131I]mIBG, stored under various
conditions, are presented. The stability was followed during 14 days. The most
important radiochemical impurity in [131I]mIBG is free [131I]iodide, formed by
radiolysis. The results indicate that the rate of radiolytic decomposition of
[131I]mIBG is much slower at higher concentration of ascorbic acid (20 mg/mCi)
and at lower storage temperature (40C).

AB  - Introduction: The aim of this study was to find out if Y-90 could form a stabile complex with meso-2,3-dimercaptosuccinic acid (DMSA) and if Y-90-DMSA may have potential for tumor therapy in the palliative treatment of bone metastases. Methods: The preparing of Y-90-DMSA was carried out by varying experimental parameters, such as ligand concentration, pH, time, and temperature of the reaction, in order to maximize the labeling yield. Analysis of the complexes enclosed the radiochemical quality control (instant thin-layer chromatography, paper chromatography, and high-performance liquid chromatography), determination of pharmacokinetical parameters as well as biodistrbution study in health male Wistar rats. In vitro stability of the complexes was tested too. Results: Y-90-DMSA could be prepared in high yields ( GT 95%) under optimized conditions of reaction. Stability studies in saline and human serum in vitro showed no significant release of activity from the ligand over 24 hours and 10 days, respectively. The preliminary biodistribution results in rat at 2 hours indicated that Y-90-DMSA, at both pH levels, was significantly retained into bone. The uptake in the kidneys was lower for Y-90-DMSA at pH 8.0 then at pH 3.0. The retention in other organs was negligible. Conclusions: Y-90 complexes could be made with ease with DMSA. Y-90-DMSA was obtained in good yield and was found to be very stable. A promising biodistribution result of this complex pointed at potential in the palliative treatment of bone metastases.

AB  - The present study describes for the first time a procedure for the radiolabeling of fullerene (C-60) nanocrystals (nanoC(60)) with Na I-125, as well as the biodistribution of radiolabeled nanoC(60) (I-125-nanoC(60)). The solvent exchange method with tetrahydrofuran was used to make colloidal water suspensions of radiolabeled nanoC(60) particles. The radiolabeling procedure with the addition of Na I-125 to tetrahydrofuran during dissolution of C-60 gave a higher radiochemical yield of radiolabeled nanoC(60) particles in comparison to the second option, in which Na I-125 was added after C-60 was dissolved. Using photon correlation spectroscopy and transmission electron microscopy, I-125-nanoC(60) particles were found to have a crystalline structure and a mean diameter of 200-250 nm. The I-125-nanoC(60) had a particularly high affinity for human serum albumin, displaying 95% binding efficiency after 1 h. Biodistribution studies of I-125-nanoC(60) in rats indicated significant differences in tissue accumulation of I-125-nanoC(60) and the radioactive tracer Na I-125. The higher accumulation of radiolabeled nanoC(60) was observed in liver and spleen, while accumulation in thyroid, stomach, lungs and intestines was significantly lower in comparison to Na I-125. In addition to being useful for testing the biological distribution of nanoC(60), the described radiolabeling procedure might have possible applications in cancer radiotherapy.

AB  - Several types of generators have been developed for the production of (99m)Tc. Due to its excelent performances, the chromatographic type, based on the fission-produced (99)Mo sorbed in alumina, is predominant. Technetium-99m is obtained in the form of sodium pertechnetate-(99m)Tc. However, due to the known disadvantages of the production of (n, f)(99)Mo, attempts are made to avoid uranium fission. The technologies based on (n, gamma)(99)Mo (sublimation, extraction, gel) are, with the exception of the gel generator, of limited importance. Certain nuclear reactions in cyclotrons can produce (99)Mo (or directly (99m)Tc) but the obtained results are still not satisfying. Technetium-99m is used in the form of radiopharmaceuticals which are prepared by addition of (99m)Tc-eluate to the inactive components comprised in the cold kits. The chromatographic (n, f)(99)Mo/(99m)Tc generator and several (99m)Tc-radiopharmaceuticals have been developed and are regularly produced in the Vinca Institute of Nuclear Sciences (Laboratory for Radioisotopes).

AB  - In the present study, we compared the effects of nanocrystalline fullerene suspension (nanoC(60)) on tumour cell growth in vitro and in vivo. NanoC(60) suspension was prepared by solvent exchange using tetrahydrofuran to dissolve C-60. In vitro, nanoC(60) caused oxidative stress, mitochondrial depolarization and caspase activation, leading to apoptotic and necrotic death in mouse B16 melanoma cells. Bio-distribution studies demonstrated that intraperitoneally injected radiolabeled (I-125) nanoC(60) readily accumulated in the tumour tissue of mice subcutaneously inoculated with B16 cells. However, intraperitoneal administration of nanoC(60) over the course of two weeks starting from melanoma cell implantation not only failed to reduce, but significantly augmented turnout growth. The tumour-promoting effect of nanoC(60) was accompanied by a significant increase in splenocyte production of the immunoregulatory free radical nitric oxide (NO), as well as by a reduction in splenocyte proliferative responses to T- and B-cell mitogens ConcanavalinA and bacterial lipopolysaccharide, respectively. A negative correlation between NO production and splenocyte proliferation indicated a possible role of NO in reducing the proliferation of splenocytes from nanoC(60)-injected mice. These data demonstrate that nanoC(60), in contrast to its potent anticancer activity in vitro, can potentiate tumour growth in vivo, possibly by causing NO-dependent suppression of anticancer immune response.

AB  - The goal of this investigation was to examine the possibilities for yttrium-90-labeling of the 2,3-dicarboxypropane-1,1-diphosphonic acid (DPD), which is currently labeled with technetium-99m and as a Tc-99m-DPD clinically used as bone imaging agent. Analysis of the complex enclosed the radiochemical quality control methods, biodistribution studies, as well as the determination of pharmacokinetic parameters. The biological behavior of complexes Y-90-DPD, Tc-99m-DPD and Y-90-labeled DPD-kit formulation [Y-90-(Sn)-DPD] in animal model was compared. The labeling conditions were standardized to give the maximum yield, which ranged between 93% and 98%. The examined Y-90 complex could be easily prepared, with an outstanding yield and was also found to be very stable for at least 10 h after Y-90-labeling. Protein binding value was 4.6 +/- 0.7% for Y-90-DPD complex and the complex possess a hydrophilic character. The satisfactory results of Y-90- DPD biodistribution in healthy test animals were obtained; the uptake in the bone was 11-13% ID/g after 24 h depending on the pH value during the preparation. With high skeletal uptake, a minimum uptake in soft tissues and rapid blood clearance the Y-90-DPD complex proved to be an excellent candidate for targeting tumor therapy. (C) 2008 Elsevier Ltd.

AB  - Colloidal particle size is an important characteristic to consider when choosing a radiopharmaceutical for diagnosis and therapeutic purposes in nuclear medicine. Photon correlation spectroscopy (PCS) and transmission electron microscopy (TEM) were used to determine the particle-size distribution of (90)Y- and (99m)Tc-labelled antimony trisulfide (Sb(2)S(3)) and tin colloids (Sn-colloid). (90)Y-Sb(2)S(3) and (99m)Tc-Sb(2)S(3) were found to have a diameter of 28.92 +/- 0.14 and 35.61 +/- 0.11 nm, respectively, by PCS. By TEM, (90)Y-Sb(2)S(3) particles were measured to be 14.33 +/- 0.09 nm. (90)Y-labelled Sn colloid were found to exist with a d(v(max1)) of 805 nm and a d(v(max2)) of 2590 nm, by PCS, whereas (99m)Tc-Sn colloid was shown to have more than 80% of radioactive particles of approximately 910 nm by PCS. For (90)Y-labelled Sb(2)S(3) and Sn colloid, a comparison of TEM and PCS indicates that these techniques found significantly different mean diameters. TEM has an excellent resolution necessary for radiocolloid particle-sizing analysis, and it is a desirable size-measuring technique because it is more reliable than PCS.

abstract = "Colloidal particle size is an important characteristic to consider when choosing a radiopharmaceutical for diagnosis and therapeutic purposes in nuclear medicine. Photon correlation spectroscopy (PCS) and transmission electron microscopy (TEM) were used to determine the particle-size distribution of (90)Y- and (99m)Tc-labelled antimony trisulfide (Sb(2)S(3)) and tin colloids (Sn-colloid). (90)Y-Sb(2)S(3) and (99m)Tc-Sb(2)S(3) were found to have a diameter of 28.92 +/- 0.14 and 35.61 +/- 0.11 nm, respectively, by PCS. By TEM, (90)Y-Sb(2)S(3) particles were measured to be 14.33 +/- 0.09 nm. (90)Y-labelled Sn colloid were found to exist with a d(v(max1)) of 805 nm and a d(v(max2)) of 2590 nm, by PCS, whereas (99m)Tc-Sn colloid was shown to have more than 80% of radioactive particles of approximately 910 nm by PCS. For (90)Y-labelled Sb(2)S(3) and Sn colloid, a comparison of TEM and PCS indicates that these techniques found significantly different mean diameters. TEM has an excellent resolution necessary for radiocolloid particle-sizing analysis, and it is a desirable size-measuring technique because it is more reliable than PCS.",

AB  - Purpose. The fullerene (C-60/C-70 mixture-C-60/70) nanocrystalline suspension prepared by solvent exchange method using tetrahydrofyran (THF/nC(60/70)) and polyhydroxylated C-60/70 [C-60/70(OH)(n)] were compared for their ability to modulate cytotoxicity of the proinflammatory cytokine tumor necrosis factor (TNT). Materials and Methods. TNF-induced cytotoxicity was assessed in L929 fibrosarcoma cells by crystal violet assay. The type of cell death (apoptosis/necrosis), production of reactive oxygen species, mitochondrial depolarization and caspase activation were determined by flow cytometry using the appropriate reporter dyes. Results. THF/nC(60/70) augmented, while C-60/70(OH)(n) reduced the cytotoxicity of TNF. The numbers of cells undergoing apoptosis/necrosis, as well as of those displaying the activation of apoptosis-inducing enzymes of caspase family, were respectively increased or reduced by THF/nC(60/70) or C-60/70(OH)(n). The antioxidant N-acetylcysteine and mitochondrial permeability transition inhibitor cyclosporin A each partly blocked the cytotoxic action of TNF, indicating the involvement of oxidative stress and mitochondrial dysfunction in the TNF cytotoxicity. Accordingly, THF/nC(60/70) or C-60/70(OH)(n) potentiated or suppressed, respectively, TNF-triggered oxidative stress and mitochondrial depolarization. Conclusion. The ability of different fullerene preparations to modulate TNF-induced oxidative stress and subsequent cell death suggests their potential value in the TNF-based cancer therapy or prevention of TNF-dependent tissue damage.
