Bifluranol, a novel fluorinated bibenzyl anti-androgen, its chemistry and disposition in different animal species.
The synthesis of bifluranol, a new fluorinated bibenzyl anti-androgen, and of 3H-labelled bifluranol is described. The absorption, distribution and excretion of bifluranol has been studied in mouse, rat, ferret and dog; it is readily absorbed following oral administration, but blood concentrations of the drug are low due to hepatic uptake and biliary excretion. Enterohepatic re-circulation occurs, but the drug is excreted primarily in the faeces and only small amounts appear in urine. This pattern of disposition and excretion is similar to that reported elsewhere for the bibenzyl, hexoestrol, and for the stilbene, diethylstilboestrol.
