Identification and Profiling of Metabolites of [14C]PF-02341066 in Plasma
Identification was done by Radio-High Performance liquid chromatography (HPLC) chromatogram. Relative abundance (profiling) of metabolites in chromatogram were determined by dividing sum of radioactive content of fractions contributing to particular peak by sum of radioactive content of all fractions constructing the radio chromatogram. Metabolites accounting for an average of greater than or equal to (\>=) 10% of total recoverable radioactivity in plasma were summarized. Radioactivity corresponds to 100 μCi \[14C\] PF-02341066.

Identification and Profiling of Metabolites of [14C]PF-02341066 in Feces
In feces, metabolite abundance (profiling) was calculated by multiplying the fractional contribution of radioactive response for the peak in the Radio-HPLC chromatogram to the total radioactivity detected by the percent of administered dose recovered in the matrix. Only those metabolites that were a component of a chromatographic peak that accounted for an average of \>=1% of the administered dose, were summarized. Radioactivity corresponds to 100 μCi \[14C\] PF-02341066.
