TG4-155 is a potent, brain-permeant and selective EP2 receptor antagonist with a Ki of 9.9 nM[1][2]. TG4-155 shows low nanomolar antagonist activity against only EP2 and DP1[1]. TG4-155 has an EP2 Schild KB of 2.4 nM and displays 550-4750-fold selectivity for EP2 over EP1, EP3, EP4 and IP, but only 14-fold selectivity against the DP1 receptor[2].
