Carbamazepine is an anticonvulsant associated with a high risk for severe cutaneous reactions. Upon metabolism by cytochrome P450, carbamazepine may produce reactive metabolites. We evaluated in vitro the covalent binding of carbamazepine reactive metabolites on human P450s and then the presence of these P450s in human epidermis. Carbamazepine reactive(More)
Transcription by RNA polymerase I (pol I) regulates the rate of ribosome biogenesis and the biosynthetic potential of the cell; therefore, it plays an important role in the control of cell growth. Differentiation of the human promyelocytic leukemic cell line U937 is accompanied by drastic decreases in pol I transcriptional activity. We have used cell-free(More)
Flavonoids are secondary metabolites that are present at high levels in the Polugonum minus. In recent years, flavonoids have attracted the interest of researchers because of their antioxidant properties .Flavonoids are synthesised via the condensation of 4 coumaryl-CoA and 3 malonyl-CoA by the action of Chalcone synthase. A cDNA encoding a chalcone(More)
