生物活性

CJ-42794 is a selective prostaglandin E receptor subtype 4 (EP4) antagonist, inhibits [3H]-PGE2 binding to the human EP4 receptor with a mean pKi of 8.5, a binding affinity that was at least 200-fold more selective for the human EP4 receptor than other human EP receptor subtypes (EP1, EP2, and EP3). IC50 value: 8.5 (pKi ) [1] Target: EP4 in vitro: CJ-042794 competitively inhibits PGE2-evoked elevations of intracellular cAMP levels in HEK293 cells overexpressing human EP4receptor with a mean pA2 value of 8.6. PGE2 inhibits the lipopolysaccharide (LPS)-induced production of tumor necrosis factor α (TNFα) in human whole blood (HWB); CJ-042794 reverses the inhibitory effects of PGE2 on LPS-induced TNFα production in a concentration-dependent manner. [1] in vivo: CJ-42794 significantly delays the ulcer healing in rats and mice. The expression of VEGF in primary rat gastric fibroblasts was increased by PGE2 or AE1-329 (EP4 agonist), and these responses were both attenuated by coadministration of CJ-42794.[2]
