N-[(5-Bromo-2-methoxyphenyl)sulfonyl]-3-[2-(2-naphthalenylmethyl)phenyl]-2-propenamide

L-798106 is a potent and selective prostanoid receptor EP3-selective antagonists. L-798106 has been used in multiple studies to tease out EP3 agonist activity, both in vitro and in vivo. L-798106 successfully blocks the actions of sulprostone, an EP3-selective agonist. L-798106 was useful in showing that the vascular contraction effect of PGE2 is due to its prostanoid EP3 agonist activity.

L-798106, a selective prostanoid receptor EP3 antagonist, is used in prostanoid receptor signaling studies that regulate COX-2 levels and the central excitatory effects of PGE(2) on PVN neurons.

ChEBI: L-798106 is an N-sulfonylcarboxamide resulting from the formal condensation of the carboxy group of o-naphthalen-2-ylcinnamic acid with the sulfonamide group of 5-bromo-2-methoxybenzenesulfonamide. It is a selective antagonist for the prostanoid receptor EP3, a prostaglandin receptor for prostaglandin E2 (PGE2). It has a role as a prostaglandin receptor antagonist. It is a N-sulfonylcarboxamide, a member of bromobenzenes and an aromatic ether.

L-798106 was among the first prostanoid receptor EP3-selective antagonists. It has been used in multiple studies to tease out EP3 agonist activity, both in vitro and in vivo. It successfully blocks the actions of sulprostone, an EP3-selective agonist, and it helped show that the vascular contraction effect of PGE2 is due to its prostanoid EP3 agonist activity.
