“Effective treatment of obesity could find more reduce the burden of diseases primarily driven by excess body weight (e.g., Type 2 diabetes). At present, effective nonsurgical weight management tools are scarce. This paper reviews the investigational combination of phentermine, a weight-loss drug available for over half a century, and topiramate, an antiepileptic drug with known weight-loss effects, as a proposed anti-obesity intervention. The combination therapy achieves weight loss of a magnitude that meets the expectations of the US FDA along with improvement of some obesity-related risks. The safety profile is consistent with known adverse
effects of individual constituents; cognitive and psychiatric adverse events were dose dependent. Other safety concerns include a small increase in heart rate and potential teratogenicity associated with topiramate.”
“Plant genomes contain a vast number of oxygenase genes, but only very few have been functionally characterized. To devise an alternative method BMS-345541 order for the detection of novel oxygenase-catalysed reactions the effects of the cytochrome P450 oxygenase inhibitors 1-aminobenzotriazole (ABT) and tetcyclacis (TET) have been examined by metabolite profiling analysis in tomato fruit (Solanum lycopersicum). Treatment with TET resulted in significant increases in the levels of certain flavonoids, whereas ABT strongly inhibited their formation during fruit ripening. Injections of buffered solutions of ABT into
tomato fruits led rather selleck compound to an accumulation of 9,12,13-trihydroxy-10(E)-octadecenoic acid probably due to retarded metabolism of the hydroxylated acid, while TET completely repressed its formation. Peroxygenase, a hydroperoxide-dependent hydroxylase involved in the formation of the trihydroxy fatty acid, is strongly inhibited by TET (IC(50) 2.6 mu M) as was demonstrated by studies with the recombinant tomato enzyme expressed in yeast. The data show that ABT and TET affect oxygenases differently in tomato fruit and reveal that these enzymes catalyse distinct reactions in different metabolic pathways, among which C(18)-trihydroxy fatty acid and flavonoid metabolism involve novel oxygenase-catalysed reactions. The method is suitable to identify potential substrates and products of ripening-related, putative oxygenases and can support functional analyses of recombinant enzymes.
