| Description: | The potency of inhibition of compound I and compound II on prostaglandin F2α receptor was assessed by analyzing the affinity of these compounds for recombinant FP receptor expressed in HEK293-EBNA cells. The results show high binding affinity of compound I and compound II to the human receptor. Selectivity of compound II was tested against all eight prostaglandin receptor subtypes. Selectivity was approximately 10-fold versus prostaglandin E receptor 2 (EP2) and higher than 100-fold against other receptors. Testing the effect of 1 μM compound II against a panel of 50 receptors, channels and enzymes binding sites showed high selectivity for FP. The functional characterization of compound II on human FP was performed in transfected HEK293-EBNA cells. |
