Implication of cysteine residues in the selection of oxorhenium inhibitors of cyclophilin hCyp18.

Metallomics 4(2) , 179-87, (2012)

The dynamic combinatorial assembly of libraries of modular cyclophilin hCyp18 oxorhenium inhibitors of general formula [A˙ReO˙B] was accelerated by addition of increasing concentrations of hCyp18 ('Cyclophilin Enhancing Effect', CEE). This result suggested th...

Immobilization, trapping, and anion exchange of perrhenate ion using copper-based tripodal complexes.

Inorg. Chem. 50(19) , 9499-507, (2011)

We describe a multidentate tripodal ligand in which three pendant arms carrying di(2-picolyl)amine units are linked to the ortho positions of a tris(o-xylyl) scaffold, providing N(CH(2)-o-C(6)H(4)CH(2)N(CH(2)py)(2))(3) (L). Reaction of L with CuCl(2) in the p...

Synthesis of oxorhenium(V) complexes with diamido amine ancillary ligands and their role in oxygen atom transfer catalysis.

Inorg. Chem. 48(23) , 11058-66, (2009)

The detailed syntheses of complexes of the form [Re(O)(X)(RNCH(2)CH(2))(2)N(Me)] (X = Me, Cl, I, R = mesityl, C(6)F(5)), 1-3, incorporating diamidoamine ancillary ligands are described. X-ray crystal structures for the complexes [Re(O)(Me)((C(6)F(5))NCH(2)CH(...

An easily accessible Re-based catalyst for the selective conversion of methanol: evidence for an unprecedented active site structure through combined operando techniques.

Chem. Commun. (Camb.) 47(14) , 4285-7, (2011)

Heterogeneous Re/SiO(2) catalysts prepared using a one pot sol-gel synthesis were found to display high activity in the direct, selective methanol conversion to methylal, which is correlated to an unprecedented rhenium oxide structure.

Heterometallic cerium(IV) perrhenate, permanganate, and molybdate complexes supported by the imidodiphosphinate ligand [N(i-Pr2PO)2]-.

Inorg. Chem. 52(5) , 2556-63, (2013)

Heterometallic cerium(IV) perrhenate, permanganate, and molybdate complexes containing the imidodiphosphinate ligand [N(i-Pr2PO)2](-) have been synthesized, and their reactivity was investigated. Treatment of Ce[N(i-Pr2PO)2]3Cl (1) with AgMO4 (M = Re, Mn) aff...

Synthesis, in vitro screening and in vivo evaluation of cyclic RGD analogs cyclized through oxorhenium and oxotechnetium coordination.

Eur. J. Med. Chem. 46(5) , 1779-88, (2011)

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 s...

Rh2O3 versus IrO2: relativistic effects and the stability of Ir4+.

J. Phys. Condens. Matter 24(21) , 215503, (2012)

Despite the wide-ranging applications of binary Rh and Ir oxides, their stability and trends in Rh and Ir oxidation states are not fully understood. Using first-principles electronic structure calculations, we demonstrate that the origin of the categorical st...

Stealth rare earth oxide nanodiscs for magnetic resonance imaging.

Adv. Healthc. Mater. 1(4) , 437-42, (2012)

Configuring RE(2) O(3) nanocrystals with pseudo-2D morphologies confers substantive gains in relaxivities over equivalent spherical counterparts. The most promising arises from Gd(2) O(3) whose ionic transverse and longitudinal relaxivities were as high as r(...

Intracellular anion fluorescence assay for sodium/iodide symporter substrates

Anal. Biochem. 415(1) , 32-8, (2011)

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 substrat...

Evaluation of [18F]-tetrafluoroborate as a potential PET imaging agent for the human sodium/iodide symporter in a new colon carcinoma cell line, HCT116, expressing hNIS.

Nucl. Med. Commun. 32(2) , 98-105, (2011)

Accumulation of iodide and other substrates via the human sodium/iodide symporter (hNIS) is fundamental to imaging and therapy of thyroid disease, hNIS reporter gene imaging and hNIS-mediated gene therapy. There is no readily available positron emission tomog...
