The LPS antagonist polymixin B; the nonselective COX inhibitor indomethacin; the selective COX-1 and COX-2 inhibitors 5-(4-chlorophenyl)-1-(4-methoxyphenyl)-3-(trifluoromethyl)-1H-pyrazole (SC560) and 4-[5-(4-chlorophenyl)-1-(trifluoromethyl)-1H-pyrazol-1-yl]-benzenesulfonam ide (SC236), respectively; the transcription inhibitor actinomycin D; the translation inhibitor cycloheximide; the p38 mitogen-activated protein kinase (p38 MAPK) inhibitor 4-(4-fluorophenyl)-2-(4-methylsulfinylphenyl)-5-(4-pyridyl)-1H-imadazole (SB203580); and a combination of the mixed DP/EP1/EP2 receptor antagonist 6-isopropoxy-9-xanthone-2-carboxylic acid (AH6809) and the EP4 receptor antagonist 4'-[3-butyl-5-oxo-1-(2-trifluoromethyl-phenyl)-1-5-dihydro-[1,2,4] triazol- 4-ylmethyl]-biphenyl-2-sulfonic acid (3-methyl-thiophene-2-carbonyl)-amide (L-161982) all abolished relaxation to LPS, giving instead slowly developing, small contractions over 60 min.

Experiments with agonists and antagonists of the PGE2 receptor subtypes EP1-EP4 indicate that PGE2 activates Stat3 mainly through the EP4 receptor.
Nuclear Stat3 phosphorylation induced by PGE2 is also suppressed by the translation and transcription inhibitors, cycloheximide and actinomycin D, respectively.
