Target	NF-κB
In Vitro	(R)-(-)-Ibuprofen is the R enantiomer of Ibuprofen, with no inhibitory effect on COX, but is involved in pathways of lipid metabolism and is incorporated into triglycerides along with endogenous fatty acids[1]. (R)-(-)-Ibuprofen (1 μM) significantly reduces NF-κB activation and completely prevents NF-κB induction at 10 μM. (R)-(-)-Ibuprofen inhibits NF-κB luciferase activity with an IC50 of 121.8 μM, weaker than that of S(+)-ibuprofen (IC50, 61.7 μM). Furthermore, (R)-(-)-Ibuprofen (10 mM) has no effect on HSF[2].
