Problem:The antidepressant drug fluoxetine (FLU) is considered in the group of selective serotonine re-uptake inhibitors. Its distribution in brain and binding to human brain glutathione S-transferase- (GST-) have been shown. FLU can cross blood brain barrier and placenta, accumulate in fetus and may cause congenital malformations.', 'To elucidate the interaction of placental GST- with FLU.', 'First, concentration-dependent inhibition of human placental GST- was evaluated by using different FLU concentrations and then 0.3125, 0.625, 1.25, 2.5 and 5mM FLU concentrations were chosen and tested while keeping GSH concentration constant and 1-chloro-2,4-dinitrobenzene (CDNB) concentration varied and vice versa. The data were evaluated with different kinetic models and Statistica 9.00 for Windows.', 'The Vm, at variable [CDNB] (14216U/mg protein) was 3 times higher than the Vm obtained at variable [GSH] (494U/mg protein). On the other hand, the Km for CDNB was 10 times higher than the Km for GSH (1.990.36mM versus 0.210.06mM). The IC50 value for FLU was 8.6mM. Both at constant [CDNB] and variable [GSH] and at constant [GSH] and variable [CDNB] the inhibition types were competitive with the Ki values of 5.624.37 and 8.091.27mM, respectively.
Solution:
Does fluoxetine-induced toxicity result in human placental glutathione S-transferase- ( GST- ) dysfunction?
