Functional imaging of gene expression in vivo with short-lived positron emitter (18)F remains an unrealized goal, in part because the long reaction times and challenging protocols typically required to label nucleic acid-based molecular probes with this radionuclide (t(1/2) = 109.8 minutes). To this end, we synthesized prosthetic group(More)
Novel bis[4-hydroxy-3-methoxyphenyl]-1,6-heptadiene-3,5-dione (curcumin) complexes with the formula, ML(3), where M is Ga(III) or In(III), or of the formula, ML(2) where M is [VO](2+), have been synthesized and characterized by mass spectrometry, infrared and absorption spectroscopies, and elemental analysis. A new ligand,(More)
A series of vanadium compounds, chelated by ligands containing a thiazolidinedione moiety as an additional insulin-enhancing component, were produced in this study to create potentially synergistic compounds. A set of four bifunctional ligand precursors were synthesized: (+/-)-5-[4-[(5-hydroxy-4-oxo-4H-pyran-2-ylmethyl)amino]benzyl]thiazolidine-2,4-dione(More)
The tetrahydrosalens N,N'-bis(2-hydroxybenzyl)-ethane-1,2-diamine ((2)(1)), N,N'-bis(2-hydroxybenzyl)-(-)-1,2-cyclohexane-(1R,2R)-diamine ((2)(2)), N,N'-bis(2-hydroxybenzyl)-N,N'-dimethyl-ethane-1,2-diamine ((2)(3)), N,N'-bis(2-hydroxybenzyl)-N,N'-dibenzyl-ethane-1,2-diamine ((2)(4)), and N,N'-bis(2-(4-tert-butyl)hydroxybenzyl)-ethane-1,2-diamine ((2)(5)),(More)
This tutorial review will highlight recent advances in medicinal inorganic chemistry pertaining to the use of multifunctional ligands for enhanced effect. Ligands that adequately bind metal ions and also include specific targeting features are gaining in popularity due to their ability to enhance the efficacy of less complicated metal-based agents.

The synthesis and metal complexation of a glucosamine-appended 2,2'-dipicolylamine ligand to the tricarbonyls of 99mTc and 186Re is described; the ligand was found to bind in a tridentate fashion with the glucosamine function remaining pendant, and the 99mTc complex was found to exhibit exceptional stability towards in vitro ligand exchange experiments.
One of the hallmarks of Alzheimer's disease (AD) in the brain are amyloid-β (Aβ) plaques, and metal ions such as copper(II) and zinc(II) have been shown to play a role in the aggregation and toxicity of the Aβ peptide, the major constituent of these extracellular aggregates. Metal binding agents can promote the disaggregation of Aβ plaques, and have shown(More)
Three carbohydrate conjugated dipicolylamine chelators, 2-bis(2-pyridinylmethyl)amino)ethyl 1-deoxy-1-thio-beta-D-glucopyranoside (L(1)), 2-bis(2-pyridinylmethyl)amino)ethyl-beta-D-glucopyranoside (L(2)), and 2-bis(2-pyridinylmethyl)amino)carboxamide-N-(2-amino-2-deoxy-D-glucopyranose) (L(3)) were complexed to the [M(CO)(3)](+) core (M=Tc, Re) and the(More)
