Feprazone is a non-steroidal, anti-inflammatory compound. Feprazone is noted to be structurally similar to phenylbutazone (sc-204843; deuterium-labelled sc-219696) and has been utilized in research studies analyzing the induction of P-450 where Feprazon was reported to induce the P450 II B family of cytochromes. Metabolization of Feprazone by CYP2B is reported to occur at two positons on the side chains of the compound through a molecular modeling of the interaction of the Feprazon and mammalian CYP2B.
