GW-627368X is a novel, potent and selective competitive antagonist of prostanoid EP4 receptors with additional human TP receptor affinity. Oral administration of GW627368X showed significant tumor regression characterized by tumor reduction and induction of apoptosis. Reduction in prostaglandin E2 synthesis also led to reduced level of VEGF in plasma. GW627368X will be a valuable tool to explore the role of the prostanoid EP4 receptor in many physiological and pathological settings.

How to use

In Vitro:

GW627368 (GW627368X) appears to bind to human prostanoid TP receptors but not the TP receptors of other species. GW627368 (GW627368X) (10 μM) produces 100% inhibition of U-46619 (EC100)-induced aggregation (approximate pA2 approximately 7.0) in human washed platelets. GW627368 (GW627368X) is devoid of agonist activity and actually produced a significant and concentration-related reduction in basal cAMP levels with pIC50 value of 6.3. GW627368 (GW627368X) induces inhibition of proliferation and invasion of human SUM149 IBC tumor cells beginning at 0.1 μM, with inhibition of proliferation and invasion of MDA-MB-231 non-IBC cells at higher concentrations.

In Vivo:

GW627368 (GW627368X) (0-15 mg/kg; p.o.; every alternate day for 28 days) shows significant tumor regression characterized by tumor reduction and induction of apoptosis.
