Abstract
Besides the well-known functions performed by vitamin B12 (CblCN) in biochemical processes of the human body, an increasing interest has been raised by the possibility of its use as a transmembrane drug carrier, capable, among others, of enhancing the accumulation of inorganic cytostatics in cancer cells. The present study was aimed at determining the possibility of the formation of CblCN conjugates with Pd(II) complexes. A key aspect was their stability, which we attempted to tune by appropriate choice of ligands. Syntheses, spectroscopic analysis of postreaction systems and kinetic investigations of conjugate formation reactions, have been complemented by DFT modelling. The obtained results showed that ligand charge, geometry and electron affinity may have a significant impact on carrier binding and release leading to the activation of the Pd(II) complex. This provides a rationale to expect that with appropriate composition of the coordination sphere, it will be possible to extend the spectrum of less toxic inorganic chemotherapeutics.

Abstract
Nutrient demand is a fundamental characteristic of rapidly proliferating cells. Vitamin B12 is vital for cell proliferation; thus neoplastic cells have an increased demand for this essential nutrient. In this study we exploited the vitamin B12 uptake pathway to probe the nutritional demand of proliferating cells with a radiolabeled B12 derivative in various preclinical tumor models. We describe the synthesis and biological evaluations of copper-64-labeled B12 -ethylenediamine-benzyl-1,4,7-triazacyclononane-N,N',N''-triacetic acid (B12 -en-Bn-NOTA-(64) Cu), the first example of a B12 derivative for positron emission tomography (PET) imaging. Small-animal imaging and pharmacological evaluation show high tumor uptake ranging from 2.20 to 4.84% ID g(-1) at 6 h post-administration. Competition studies with excess native B12 resulted in a 95% decrease in tumor accumulation, indicating the specificity of this radiopharmaceutical for B12 endocytotic transport proteins. These results show that a vitamin B12 PET radiopharmaceutical has potential utility for non-invasive imaging of enhanced nutrient demand in proliferating cells.

Abstract
Three non-native derivatives of vitamin B12 with imidazole, ethylenediamine, and pyrazine as cobalt(III) β-ligands were characterized by applying the BP/def2-TZVP density functional method. The binding of all three ligands is thermodynamically favorable. It is proposed that their synthesis might be possible from aquacobalamin as a starting form of vitamin B12, as has been done in the case of an imidazole derivative of B12 (Hannibal et al. Inorg. Chem. 2007, 46, 3613-3618). Furthermore, the possibility of the formation of their conjugates with cisplatin is investigated. The proposed β-ligands may serve as bridging ligands, binding to the platin ion as N-donors. In parallel, the calculations are done for the previously synthetized B12-cisplatin adduct with CN(-) as a bridging ligand and are compared with available experimental data, allowing assessment of the applied computational protocol. A good agreement between the computed and experimental structural parameters is obtained. In each of the studied structures, the Co-β-ligand bond is weaker than the Pt-β-ligand bond.

Abstract
A side-by-side comparison of the synthesis, radiolabeling, and in vitro and in vivo characterization of two new and isostructural (99m)Tc-tricarbonyl folic acid radiotracers comprising either a N(tau)-functionalized histidine (His) chelator or a 1,4-bifunctionalized 1,2,3-triazole His analogue is described. The 1,2,3-triazole-containing folic acid derivative was synthesized in approximately 80% yield by a short reaction sequence including application of click chemistry (the Cu(I)-catalyzed cycloaddition of azides and terminal alkynes). The synthesis of the ligand system and the functionalization of the folic acid derivative were accomplished simultaneously, which prompted us to call this approach "click-to-chelate". In comparison, the reported regioselective synthesis of the N(tau)-His compound provided the final product in only very low yields (<1%). While the efficiency of the syntheses differs considerably, the two isostructural folate derivatives exhibit virtually identical properties with respect to Tc-99m radiolabeling and in vitro and in vivo characteristics as shown by experiments performed with FR-positive KB cells and xenografted mice bearing folate receptor overexpressing tumors. We have demonstrated herein for the first time that a ligand system known to be an excellent chelator for the stable complexation of the organometallic core [M(CO)3] (+) (M = Tc-99m, Re) can be replaced by an isostructural 1,2,3-triazole analogue without influencing the characteristics of the radiometal conjugate. The "click-to-chelate" strategy provides a highly efficient and convenient entry to metal conjugates suitable for diagnostic and potentially therapeutic applications. The described procedures should be readily applicable to any azide-functionalized (bio)molecule and, thus, are likely to represent the method of choice for the future development of radiopharmaceuticals radiolabeled with the organometallic precursors [M(CO)3(H2O)3] (+) (M = (99m)Tc, (188)Re).

Abstract
Abstract
Rapidly growing cells show an increased demand for nutrients and vitamins. The objective of our work is to exploit the supply route of vitamin B12 to deliver new derivatives of this vital vitamin to hyperproliferative cells. To date, radiolabeled (57Co and 111In) vitamin B12 derivatives showed labeling of tumor tissue but also undesired high accumulation of radioactivity in normal tissue. By abolishing the interaction of a tailored vitamin B12 derivative to its transport protein transcobalamin II and therefore interrupting transcobalamin II receptor and megalin mediated uptake in normal tissue, preferential accumulation of a radiolabeled vitamin in cancer tissue could be accomplished. We identified transcobalamin I on tumors as a possible new receptor for this preferential accumulation of vitamin-mediated targeting. The low systemic distribution of radioactivity and the high tumor to blood ratio opens the possibility of a more successful clinical application of vitamin B12 for imaging or therapy.
