Background Numerous knockout mouse studies have revealed that P-glycoprotein (P-gp) significantly limits drug distribution across the mouse blood-brain barrier (BBB). To determine the importance of P-gp at the human BBB, we developed a state-of-the-a

Oxidations of a trigonal-bipyramidal, high-spin Ni(II) dithiolate complex of a pentadentate, N3S2-donor ligand, N1,N9-bis(imino-2-mercaptopropane)-1,5,9-triazanonane) nickel(II), and the structurally analogous Zn(II) complex, lead to oxidations of th

To examine how small structural changes influence the reactivity and magnetic properties of biologically relevant metal complexes, the reactivity and magnetic properties of two structurally related five-coordinate Fe(III) thiolate compounds are compa

Analysis of the iron K-edge X-ray absorption spectrum (XAS) of the “dark”, inactive form of nitrile hydratase (NHdk) from Rhodococcus sp. R312 confirms a 1:1 stoichiometry of nitric oxide bound to low-spin iron(III). We also report XAS analyses o

To examine inhibitor binding to an iron site resembling that of the metalloenzyme nitrile hydratase (NHase), a coordinatively unsaturated, five-coordinate FeIII thiolate complex was synthesized, and its reactivity examined. Ferricinium hexafluorophos

Fluorine-18 is used for many PET radiopharmaceuticals. Theoretically 18F should be carrier free and a good candidate for nanochemistry. However, 18F has 10 to 1000 times more stable fluorine atoms than radioactive atoms. In order to understand the so

Sulfur-ligated Ni complexes are of interest as active-site models of the Ni-containing enzymes hydrogenase (H[sub 2]-ase), methyl coenzyme M reductase (Me-CoM reductase), and Co-dehydrogenase (CODH). Me-CoM reductase catalyzes the last step in the re
