PF-02413873 (PF-2413873) is a potent selective, fully competitive and orally active nonsteroidal progesterone receptor (PR) antagonist, with a Ki of 2.6 nM. PF-02413873 can block progesterone binding and PR nuclear translocation, and inhibit endometrial growth in vivo[1][2].
PF-02413873 shows potent PR antagonist activity with a derived Ki of 9.7 nM in the T47D native functional assay[1].PF-02413873 (1 nM-10 μM) induces nuclear translocation only at high concentrations (>3 μM)[1].
PF-02413873 (2.5 and 10 mg/kg; p.o. twice daily for 10 days) induces a statistically significant reduction in endometrial thickness in cynomolgus macaques[1].PF-02413873 (3 mg/kg; a single p.o.) exhibits t1/2 (4.2 h), Cmax (162 ng/mL) and CL/F (41 mL/min/kg)[1].
