PF-06869206 是口服有效的磷酸钠协同转运蛋白NaPi2a(SLC34A1) 选择性抑制剂，IC50为 380 nM。

PF-06869206 is an oral selective inhibitor of the sodium-phosphate cotransporter NaPi2a (SLC34A1, IC50: 380 nM).

PF-06869206 (380 nM) shows NaPi2a inhibition potency. PF-06869206 is profiled for potency in the rodent NaPi2a and NaPi2c cell lines. PF-06869206 shows comparable submicromolar activity for the human, rat, and mouse NaPi2a isoforms (IC50s: 0.4 μM/0.54 μM for rat/mouse NaPi2a).

In rodent PK, PF-06869206 show moderate clearance in both rat and mouse. Oral bioavailability at 5 mg/kg is good in rat and moderate in mouse. At higher oral doses of 50 mg/kg, supraproportional increases in exposure are observed in both species, suggestive of saturation of clearance. PF-06869206 has moderate terminal elimination half-life (t1/2=1.35 h, and 0.75 h for Wistar-Han rats (10 mg/kg, iv), and C57BL6 mice (1 mg/kg, iv)).

Male Wistar-Han rats are treated with PF-06869206 (1 mg/kg, 5 mg/kg, and 50 mg/kg; 2 mL/kg for iv or 10 mL/kg for po) . C57BL6 mice are treated with PF-06869206 (1 mg/kg, 5 mg/kg, and 50 mg/kg; 2 mL/kg for iv or 10 mL/kg for po).
