C23H20FNO5
Molecular Weight 409.41 CAS No. 1078166-57-0
Solubility (25°C)* In vitro DMSO 82 mg/mL (200.28 mM)
Ethanol 3 mg/mL (7.32 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5% DMSO 95% Corn oil
0.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 10 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
4.1mg/ml Taking the 1 mL working solution as an example, add 50 μL of 82 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description PF-04418948 is a potent and selective prostaglandin EP₂ receptor antagonist with IC50 of 16 nM. Phase 1.
Targets
EP₂ receptor [1]
16 nM
In vitro

PF-04418948 antagonizes the effects of butaprost and PGE2 on an EFS-induced contraction of the human myometrium, and antagonizes PGE2-induced relaxation of carbachol pre-contracted rings of mouse trachea. [1]

PF-04418948 competitively inhibits relaxations of murine and guinea pig trachea induced by ONO-AE1-259 and PGE2 respectively. [2]

PF-04418948 restores neutrophil extracellular traps (NETs) formation in neutrophils isolated from BMT mice or HSCT patients. [3]
In vivo

In Rats, PF-04418948 (10 mg/kg, p.o.) reduces the mean cutaneous blood flow peak response and AUC0–60 by 41% and 61%, respectively. [1]
