892549-43-8 MF63 is a potent, selective, and orally active mPGES-1 inhibitor with IC50 of 1.3 nM for human mPGES-1 enzyme, >1000-fold selectivity over other prostanoid synthases; strongly inhibits guinea pig mPGES-1 (IC50= 0.9 nM) but not the mouse or rat enzyme; selectively suppresses the synthesis of PGE(2), but not other prostaglandins inhibitable by NSAIDs, yet retains NSAID-like efficacy at inhibiting LPS-induced pyresis, hyperalgesia, and iodoacetate-induced osteoarthritic pain, relieves pyresis and pain in preclinical models of inflammation.


1234708-04-3 hPGDS-IN-1 is a potent, selective hPGDS inhibitor with IC50 of 12 nM in FP or EIA assays.


1915003-93-8 mPGES1-IN-16 is a potent and selective mPGES-1 inhibitor with IC50 of 1 nM; displays no activity against a panel of 35 receptors, ion channels, and hERG; shows IC50/IC80 of 6 nM/24 nM for inhibition of PGE2 formation in vitro in LPS-stimulated human whole blood (HWB); orally bioavailable in vivo.


1469976-70-2 mPGES1-IN-17d is a potent, selective mPGES-1 inhibitor with enzyme IC50 of 8 nM, A549 cell IC50 of 16.24 nM, human whole blood IC50 of 249.9 nM; displays excellent in vitro selectivity over mPGES-2, cPGES, COX1/2, other prostanoid synthases, favorable hERG and CEREP panel profile; shows good efficacy in LPS-induced thermal hyperalgesia pain model; demonstrates good oral pharmacokinetic profiles and good CNS B/P ratio in rat and guinea pig.


1221971-47-6 PF-9184 is a potent, selective mPGES-1 (microsomal prostaglandin E synthase-1) inhibitor with IC50 of 16.5 nM; shows no effect against COX-1 and COX-2 (>6,500-fold selectivity); inhibits PGE2 synthesis in serum-free cell and human whole blood cultures with IC50 of 0.5-5 uM, while sparing the synthesis of PGF(1alpha)) and PGF(2alpha).


1381846-21-4 A novel potent (IC50=910 ng/mL), highly selective microsomal prostaglandin E synthase 1 inhibitor (mPGES-1) for treatment of undisclosed indications.

HPGDS inhibitor 1

1033836-12-2 A potent, selective, oral hematopoietic prostaglandin D synthase (HPGDS) inhibitor with enzyme IC50 of 0.6 nM; does not inhibit human L-PGDS, mPGES, COX-1, COX-2, or 5 LOX (IC50>10 uM); reduces the antigen-induced response in vivo.
