MF-766

Biological Activity

MF-766 (MF766) is a highly potent and selective EP(4) antagonist with binding Ki of 0.23 nM, displays no significant affinity (>7000-fold selectivity) against other PG receptors (IC50>1500 nM); behaved as a full antagonist with an IC50 of 1.4 nM (shifted to 1.8 nM in the presence of 10% HS) in the functional assay; exhibits blockade of inhibition of TNFa-induced IP10 release by the specific EP4 agonist L-000902688 (IC50=9.5 nM); demonstrates potency and efficacy of in the rat AIA model measuring inhibition of paw swelling.

Published experimental findings depend on the model and assay conditions. They do not guarantee equivalent performance in every application. For laboratory research use only.
