Analysis of the peroxidase-catalysed oxidation of hydroxamic acids
… and computational modelling of the binding of hydroxamic acids to the active site of a model peroxidase (horseradish, LPO; myeloperoxidase, MPO) was used to provide insight into structure-function relationships of peroxidases. Hydroxamic acids acted as inhibitors of the native state (E), by …

DEVELOPMENT OF SYNTHETIC METHODOLOGIES TOWARDS CYCLIC HYDROXAMIC ACID-BASED NATURAL PRODUCTS
Hydroxamic acids are an important class of bioactive compounds with wide uses as anti-bacterial, or anti-inflammatory agents and a key component of many natural products, mainly siderophores (low-molecular-weight iron sequestering agents) in lower organisms. Hydroxamic acid based analogs may find …

Maize β-glucosidase substrate specificity and natural substrates
… hydrophobic aglycones. One major substrate, the hydroxamic acid 2,4-dihydroxy-7- methoxy-1, 4-benzoxazin-3-one-8-D-glucopyranoside (DIMBOA-glc), was found in methanolic maize extracts. Increasing DIMBOA levels are associated with increasing resistance to several pests. The highest levels of …

Studies on the stereo- and regiochemistry of [4+2] cycloaddition of nitroso compounds to chiral halobenzenediols. Total synthesis of lycoricidine
… derived in situ from the oxidation of hydroxamic acids, to protected halocyclohexadienediols provided chiral bicyclic oxazines of type 9, as single isomers. These compounds were converted by reductive cleavage to 1,4-hydroxy amides. The anti-addition to the acetonide and the …

Cyclic nitrones: oxidation studies and the synthesis of a heterocyclic nitrone
… by ferric chloride. This cyclic hydroxamic acid underwent further oxidation at a slower rate, ultimately yielding diglycollic acid and nitrous oxide. 1,3-Cycloaddition products were formed when the heterocyclic nitrone was heated together with cyclohexene, with phenylisocyanate …

Zum Komplexbildungsverhalten ausgewählter Actiniden (U, Np, Cm) mit mikrobiellen Bioliganden
Die Endlagerung von radioaktivem Abfall ist eine der vordringlichsten Aufgaben auf dem Gebiet der Kerntechnik. Als Teil der Sicherheitsanforderungen steht dabei der Schutz von Mensch und Umwelt vor den Gefahren der radioaktiven Stoffe selbst im Falle einer Freisetzung dieser Stoffe aus dem Endlager …

SIDEROPHORE DESFERRIOXAMINE B PROMOTED DISSOLUTION AND ADSORPTION PROPERTIES OF TITANIUM DIOXIDE BEARING MINERALS
… matrix environment by introducing small organic acids such as oxalate, citrate, humic acid, and ascorbate. They exhibited mostly synergistic effects and increased the amount of dissolved Ti except for humic acid. Understanding the dissolution of TiO2 in different environmental conditions is …
