A study of relationships between the structure of flavones, flavanones, and chalcones and their capacity to induce increased 3,4-benzpyrene (BP) hydroxylase activity in the liver and lung of the rat has been carried out. Appropriate halogenation in creases inducing activity. In the compounds studied, hydroxylation reduces inducing capacity, but the corresponding methoxy compounds are active. Tw...
Myeloperoxidase, eosinophil peroxidase and lactoperoxidase are heme-containing oxidoreductases, which undergo a series of redox reactions. Though sharing functional and structural homology, reflecting their phylogenetic origin, differences are observed regarding their spectral features, substrate specificities, redox properties and kinetics of interconversion of the relevant redox intermediates...
The synthesis of halogenated compounds in biological systems is well established, yet the mechanisms by which these compounds are formed are poorly understood. Many commercially important compounds, such as pharmaceuticals and agrochemicals, contain halogens; indeed some halogenated natural products, such as the antibiotic vancomycin, are themselves valuable. Furthermore, several environmentall...
