DT-9081
DT-9081 is an orally active and selective EP4 receptor antagonist, IC50 = 2.49 nM. DT-9081 blocks PGE2/EP4R-mediated cAMP signaling, counteracts EP4R-driven immunosuppression, and restores antitumor immunity. DT-9081 combined with anti-PD-1 antibody significantly improves tumor growth inhibition and animal survival in mouse tumor models. DT-9081 can be used in cancer-related research.

In Vitro
DT-9081 (compound 10m) is a potent antagonist of human EP4R in the human HEK-293 EPAC BRET cAMP assay, with an IC50 of 2.49 nM, and maintains nanomolar potency against mouse, rat, and dog EP4R; it blocks EP4R/cAMP signaling in human IL-2-activated T cells, with an IC50 of 65 nM[1].
DT-9081 binds EP4R with an inhibition rate of 100.1% and is highly selective for other prostanoid receptors[1].
DT-9081 (10 μM) shows no significant off-target activity in the Safety Screen 87 panel, except for 62% binding inhibition of 5-HT2B, and has no functional 5-HT2B activity[1].
DT-9081 exhibits acceptable cross-species in vitro stability, a high plasma protein binding rate, and inhibits CYP2C8/2C19 and OATP1B1/1B3/BCRP[1].
DT-9081 (30 μM) weakly inhibits hERG in stably transfected CHO cells, with an inhibition rate of 16.7%[1].

In Vivo
DT-9081 (30 mg/kg; p.o.; twice daily; day 8 to day 28) shows low single-agent activity in the 4T1 triple-negative breast cancer model, but when combined with anti-PD-1 and Cisplatin (HY-17394), it increases the response rate[1].
