Plants and seeds are the main dietary sources of zinc, iron, manganese, copper, but also entry point for toxic elements such as cadmium into food chain. We report here that an Arabidopsis oligopeptide transporter mutant, opt3-2, over-accumulates (Cd) in roots but, unexpectedly, under-accumulates Cd leaves. The distribution opt3-2 differs from suggesting a metal-specific mechanism metal partitioning within plant. mutant constitutively up-regulates Fe/Zn/Cd IRT1 FRO2 roots, indicative...
The BB2 receptor subtype, of the bombesin family receptors, has been shown to be highly overexpressed in a variety human tumors, including prostate cancer. Bombesin (BBN), 14-amino acid peptide, target with high affinity. 64Cu (half-life = 12.7 h, beta+: 18%, E(beta+ max) 653 keV; beta-: 37%, E(beta- 578 keV) is radioisotope that clinical potential for application both diagnostic imaging and radionuclide therapy.

Background: As part of our continuing quest to enhance the efficacy bioactive phytochemicals in cancer therapy, we report an innovative green nanotechnology approach toward use resveratrol for production biocompatible resveratrol-conjugated gold nanoparticles (Res-AuNPs). Our overarching aim is exploit inherent pro-apoptotic properties (AuNPs) through synergistic anti-tumor characteristics resveratrol, with developing a new class nanotechnology-based phytochemical-embedded AuNPs applications...
Extraction of trace pertechnetate (99mTcO4–) from aqueous media using hydrophobic deep eutectic solvents (DESs) is reported for the first time. The DESs studied comprise a 1:2 molar ratio tetraalkylammonium or tetraalkylphosphonium halide mixed with monocarboxylic acid (i.e., saturated fatty acid). Quantitative (>99%) removal tracer levels 99mTcO4– an phase in presence large excess competing anions (e.g., Cl–, NO3–, HCO3–, H2PO4–, SO42–) within 5–60 min at 25 °C without aid formal extracting...
Abstract The OLIGOPEPTIDE TRANSPORTER 3 (OPT3) has recently been identified as a component of the systemic network mediating iron (Fe) deficiency responses in Arabidopsis. Reduced expression OPT3 induces an over accumulation Fe roots and leaves, due part by elevated IRON‐REGULATED 1. Here we show however, that opt3 leaves display transcriptional program consistent with overload, suggesting excess is properly sensed OPT3‐mediated shoot‐to‐root signaling critical to prevent overload. We also...
α-Melanocyte stimulating hormone (α-MSH) analogs, cyclized through site-specific rhenium (Re) and technetium (Tc) metal coordination, were structurally characterized analyzed for their abilities to bind α-MSH receptors present on melanoma cells in tumor-bearing mice. Results from receptor-binding assays conducted with B16 F1 murine indicated that affinity was reduced approximately 1% of its original levels after Re incorporation into the cyclic Cys 4,10 , d -Phe 7 –α-MSH 4-13 analog....

Nanocompatible chemistry which utilizes a novel nontoxic phosphino amino acid as reducing agent has resulted in the development of therapeutically useful gold nanoparticles under biologically benign media. Stabilization by edible gum arabic matrix provided an effective pathway toward vivo stable target-specific nanoparticles.
Radiometals play an important role in diagnostic and therapeutic radiopharmaceuticals. This field of radiochemistry is multidisciplinary, involving radiometal production, separation the from its target, chelate design for complexing a biologically stable environment, specific targeting to vivo site, nuclear imaging and/or radiotherapy applications resultant radiopharmaceutical. The critical importance inorganic chemistry application radiometal-containing therapy agents described historical...
Abstract Diagnostic and therapeutic nuclear medicine relies heavily on radiometal nuclides. The most widely used well-known radionuclide is technetium-99m ( 99m Tc), which has dominated diagnostic since the advent of 99 Mo/ Tc generator in 1960s. Since that time, many more radiometals have been developed incorporated into potential radiopharmaceuticals. One critical aspect radiometal-containing radiopharmaceuticals their stability under vivo conditions. chelator coordinated to a key factor...
