Reactions between iron porphyrins and tetrahydropterins

Autor: Daniel Mansuy, Pierrette Battioni, Jean-Luc Boucher, Delphine Mathieu

Publikováno v: Journal of Porphyrins and Phthalocyanines. :265-278

Data from the last few years have revealed a novel biological role of the tetrahydrobiopterin ( H4B ) cofactor, in one-electron transfers to the heme of the active site of NO-synthases (NOSs) with intermediate formation of a H4B -derived radical. The

Publikováno v: Comptes Rendus Chimie. 5:263-266

The non-heme iron complex, Fe(TPAA = tris-〚N-(2-pyridylmethyl)-2-aminoethyl〛amine)(ClO4)2, is a bad catalyst for the epoxidation of alkenes such as cyclooctene, cyclohexene and cis-stilbene and for the hydroxylation of alkanes such as adamantane

Publikováno v: Comptes Rendus de l'Académie des Sciences - Series IIC - Chemistry. 3:751-755

Preparative hydroxylation of aromatic compounds such as drugs remain a difficult challenge. Here we show that the two main human metabolites of the anti-inflammatory drug diclofenac, 5-hydroxy- and 4′-hydroxy-diclofenac, can be prepared from diclof

Publikováno v: Journal of Molecular Catalysis A: Chemical. 158:521-531

Surface derivatization of titanium dioxide nanoparticles with a Fe(III)–porphyrin has been carried out following a new procedure whereby the complex, rather than the surface, contains the aminopropylsilane functional group. This avoids the problems

A comparison of the oxidations of diclofenac with microsomes of yeasts expressing various human liver cytochromes P450 showed that P450 2C9 regioselectively led to 4'-hydroxy diclofenac (4'-OHD) whereas P450 3A4 only led to 5-hydroxy diclofenac (5-OH

Autor: Daniel Mansuy, Jean-Luc Boucher, Pierrette Battioni, Jason Hart-Davis

Publikováno v: Journal of the American Chemical Society. 120:12524-12530

Various iron porphyrin systems were found to catalyze the dehydration of aldoximes, such as heptanaldoxime or phenylacetaldoxime, into the corresponding nitriles under mild conditions (t = 20 °C, neutral or slightly acidic pH). In all these systems,
