AH 6809 is an antagonist of prostaglandin receptor EP1, EP2 and D2 .
In COS-7 cells transfected with human EP2 receptor, AH 6809 treatment selectively inhibited the cAMP production increased by PGE2 but not forskolin. In the non-small cell lung cancer NCI-H1299 cell line, AH 6809 inhibited the binding of 3H-PGE2 to the cell membrane with IC50 value of 5 μM. The compound also inhibited the increase in cAMP level caused by PGE2 in NCI-H1299 cells. Moreover, AH 6809 significantly suppressed the cell proliferation and colony formation at low micromolar concentration. Besides that, AH 6809 exerted to be a specific DP-receptor blocking drug. It inhibited the anti-aggregation activity of PGD2 in whole blood [1, 2 and 3].
