Prostaglandin E2 evokes distinct responses through four different 'E prostanoid' (EP) receptors. EP2 is a G protein-coupled receptor that has diverse roles, including those in cancer, inflammation, and neuroprotection. TG6-129 is an antagonist of the EP2 receptor, suppressing PGE2-induced elevation of cAMP in cells expressing EP2 with an IC50 value of 1.6 µM. It is without effect on EP4, DP1, IP, and β2-adrenergic receptors. TG6-129 reduces the expression of COX-2, IL-1β, IL-12, IL-23, IL-6, and TNF-α induced by the EP2-selective agonist butaprost in P388D1 macrophages. It has low cell cytotoxicity (CC50 = 326 µM), prolonged plasma half-life, and does not cross the blood-brain barrier.

Targeting EP2 receptor with multifaceted mechanisms for high-risk neuroblastoma
Cell Rep 2022 Jun 21;39(12):111000.PMID:35732130DOI:10.1016/j.celrep.2022.111000.
Prostaglandin E2 (PGE2) promotes tumor cell proliferation, migration, and invasion, fostering an inflammation-enriched microenvironment that facilitates angiogenesis and immune evasion. However, the PGE2 receptor subtype (EP1-EP4) involved in neuroblastoma (NB) growth remains elusive. Herein, we show that the EP2 receptor highly correlates with NB aggressiveness and acts as a predominant Gαs-coupled receptor mediating PGE2-initiated cyclic AMP (cAMP) signaling in NB cells with high-risk factors, including 11q deletion and MYCN amplification. Knockout of EP2 in NB cells blocks the development of xenografts, and its conditional knockdown prevents established tumors from progressing. Pharmacological inhibition of EP2 by our recently developed antagonist TG6-129 suppresses the growth of NB xenografts in nude mice and syngeneic allografts in immunocompetent hosts, accompanied by anti-inflammatory, antiangiogenic, and apoptotic effects. This proof-of-concept study suggests that the PGE2/EP2 signaling pathway contributes to NB malignancy and that EP2 inhibition by our drug-like compounds provides a promising strategy to treat this deadly pediatric cancer.
Discovery and characterization of carbamothioylacrylamides as EP2 selective antagonists
ACS Med Chem Lett 2013 Jul 11;4(7):616-621.PMID:23914286DOI:10.1021/ml400112h.
Prostanoid receptor EP2 is emerging as a novel target for development of anti-inflammatory drugs for the treatment of chronic neurodegenerative and peripheral diseases; however, the availability of EP2 antagonist probes for exploration of peripheral disease models is very limited. We now report identification and characterization of a novel chemical class of compounds that show nanomolar potency and competitive antagonism of the EP2 receptor. A compound in this class, TG6-129, showed prolonged plasma half-life and did not cross the blood brain barrier. This compound also suppressed the induction of inflammatory mRNA markers in a macrophage cell line upon activation of EP2. Thus, this compound could be useful as a probe for a variety of peripheral chronic inflammatory diseases such as rheumatoid arthritis and chronic obstructive pulmonary disease, in which EP2 appears to play a pathogenic role.
