GW-627368X — Datasheet

Biological Activity

GW627368(GW627368X) is a novel, potent and selective competitive antagonist of prostanoid EP4 receptor(Ki= 100 nM) with additional human TP receptor affinity(Ki= 150 nM).IC50 value: Target: EP4 antagonistin vitro: At recombinant human prostanoid EP4 receptors expressed in HEK293 cells, GW627368X produced parallel rightward shifts of PGE2 concentration-effect (E/[A]) curves resulting in an affinity (pKb) estimate of 7.9 +/- 0.4. GW627368X appears to bind to human prostanoid TP receptors but not the TP receptors of other species. In human washed platelets, GW627368X (10 microM) produced 100% inhibition of U-46619 (EC100)-induced aggregation (approximate pA2 approximately 7.0) [1]. in vivo: 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 [2].
