Target
NF-κ B
in vitro studies
(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. (R)-(-)-Ibuprofen (1 μM) significantly reduces NF-κ B activation and completely prevents NF-κ B induction at 10 μM. (R)-(-)-Ibuprofen inhibits NF-κ B luciferase activity with an IC 50 of 121.8 μM, weaker than that of S( )-ibuprofen (IC 50 , 61.7 μM). Furthermore, (R)-(-)-Ibuprofen (10 mM) has no effect on HSF.
