The oxidative half-reaction of phenol hydroxylase has been studied by stopped-flow spectrophotometry. Three flavin-oxygen intermediates can be detected when the substrate is thiophenol, or m-NH2, m-OH, m-CH3, m-Cl, or p-OH phenol. Intermediate I, the flavin C(4a)-hydroperoxide, has an absorbance maximum

Technetium-99m labeling of antibodies has been suboptimal because of low affinity adventitious binding, nonspecific labeling, and loss of immunoreactivity. The diamide dithiolate ligand system (N2S2) forms highly stable, well-defined tetradentate complexes with Tc(V). Antibodies and their fragments have been labeled

Folate receptors (FR) are frequently overexpressed in a wide variety of human cancers. The aim of this study was to develop a trivalent 99mTc(CO)3-labeled folate radiotracer containing isonitrile (CN-R) as the coordinating ligand for FR target imaging. [99mTc]Tc-10 was HPLC

An investigation to prepare a phenylalanine derivative which could be radioiodinated and used directly in peptide synthesis was conducted. N-Boc-p-(tri-n-butylstannyl)-L-phenylalanine tetrafluorophenyl ester was targeted and synthesized from N-Boc-p-iodo-L-phenylalanine. The requisite aryl stannylation reaction was found to be best conducted using

In the present study the oxidative dehalogenation of a para-halogenated phenol was studied using pentafluorophenol and its non-para-halogenated analogue 2,3,5,6-tetrafluorophenol as model compounds. 19F NMR was used to characterize the metabolite patterns. In order to study the primary oxidation products
