PF-04475270
PF-04475270 is a prodrug of CP-734432 (HY-119236), as well as an agonist of the EP4 prostaglandin receptor, with IC50 values of 2 nM and 8 nM against human and canine sources, respectively. PF-04475270 is rapidly hydrolyzed into its active metabolite CP-734432 by ocular esterases or corneal homogenate, stimulates cAMP production, and activates cAMP response element-mediated β-lactamase activity in cells expressing EP4. PF-04475270 can be used in research related to glaucoma.

Animal Model:
-
Dosage:0.1 μg; 0.25 μg; 2.5 μg; 5 μg (single dose); 0.5 μg; 1.25 μg (once daily for 4 days)
-
Administration:topical; single instillation (for 0.1 μg, 0.25 μg, 2.5 μg, 5 μg); once daily; 4 days (for 0.5 μg, 1.25 μg)
-
Result:Achieved mean IOP of 73% of baseline at 24 hours post-first dose, 67% of baseline at 48 hours, 65% of baseline at 72 hours, and 65% of baseline at 96 hours for the 0.5 μg multiple-dose group.
Achieved mean IOP of 81% of baseline at 24 hours post-first dose, 64% of baseline at 48 hours, 61% of baseline at 72 hours, and 58% of baseline at 96 hours for the 1.25 μg multiple-dose group.
Demonstrated progressively greater IOP reduction with repeated daily dosing despite no accumulation of the active metabolite CP-734432 in ocular tissues.
Showed a population-based pharmacokinetic-pharmacodynamic model (model II) with a positive feedback loop captured time-dependent IOP lowering, with key parameters including a SC50 of 0.674 ng/g, a Sₘₐₓ of 0.287, and a kₘₒd of 0.029 h-1.
