PF-04971729, a potent and selective inhibitor of the sodium-dependent glucose cotransporter 2, is currently in phase 2 trials for the treatment of diabetes mellitus. Inhibitory effects against the organic cation transporter 2-mediated uptake of [14C]metformin by PF-04971729 also were very weak (IC50 900μM).The disposition of PF-04971729, an orally active selective inhibitor of the sodium-dependent glucose cotransporter 2, was studied after a single 25-mg oral dose of [14C]-PF-04971729 to healthy human subjects. The absorption of PF-04971729 in humans was rapid with a Tmax at ~ 1.0 h. Of the total radioactivity excreted in feces and urine, unchanged PF-04971729 collectively accounted for ~ 35.3% of the dose, suggestive of moderate metabolic elimination in humans.
