Uses
Darbufelone is a dual inhibitor of cellular PGF2α and LTB4 production. Darbufelone potently inhibits PGHS-2 (IC50= 0.19 μM) but is much less potent with PGHS-1 (IC50=20 μM).
Biological Activity
Darbufelone is a dual inhibitor of cellular PGF2α and LTB4 production. It potently inhibits PGHS-2 (IC50=0.19 μM), but is much less potent against PGHS-1 (IC50=20 μM).
in vivo
Darbufelone is a dual inhibitor of cellular PGF2R and LTB4 production. Darbufelone is orally active and nonulcerogenic in animal models of inflammation and arthritis.
target
IC50: 0.19 μM (PGHS-2), 20 μM (PGHS-1)
