The sodium/iodide symporter (NIS) is primarily responsible for iodide accumulation in the thyroid gland for the synthesis of thyroid hormones; however, it can also transport other lyotropic anions in the thyroid gland and nonthyroid tissues. Some NIS substrates have important

A library of RGD tripeptide analogs cyclized through oxorhenium coordination by an NS2/S chelation motif was synthesized. Screening towards integrins αVβ3, αIIbβ3 and αVβ5 led to the identification of 6 oxorhenium complexes that bind to integrin αVβ3 in the submicromolar

Radiolabeled biomolecules are routinely used for clinical diagnostics. (99m)Tc is the most commonly used radioactive tracer in radiopharmaceuticals. (188)Re and (186)Re are also commonly used as radioactive tracers in medicine. However, currently available methods for radiolabeling are lengthy and involve
