Resveratrol(trans-Resveratrol) is a phenolic phytoalexin found in grape skin and other plants; trans-Resveratrol is also a selective inhibitor of cyclooxygenase-1 (COX-1).
IC50 value:
Target: COX-1
Resveratrol produced neurotrophic effects on cultured DA neurons. Resveratrol could attenuate oxidant-induced mitochondrial damage in embryonic rat cardiomyocytes by inactivating GSK-3β via cGMP/PKG signaling pathway independent of NO-related mechanism. Because Resveratrol has anti-inflammatory, anti-oxidant, and hypotriglyceridemic effects, its supplementation may beneficially affect the increased cardiovascular risk of healthy smokers. Resveratrol merits investigation as a potential cancer chemopreventive agent in humans. trans-Resveratrol is a potent phenolic antioxidant found in grapes and red wine that also has antiproliferative and anti-inflammatory activity. trans-Resveratrol is also a selective inhibitor of cyclooxygenase-1 (COX-1). It inhibits COX and peroxidase activities of COX-1 with ED50 values of 15 and 3.7 uM, respectively; with essentially no inhibition of the COX activity of COX-2.

(R)-(-)-Ibuprofen  (R)-Ibuprofen, a nonsteroidal anti-inflammatory, is the less active enantiomer of ibuprofen, an inhibitor of Cox-1 and Cox-2.

IC50 Value: 121.8uM (inhibited the activation of NF-kB in response to T-cell stimulation) [2].
Target: COX1; COX2
S form ofibuprofen or S(+)-ibuprofen (SIB) is the biologically active isomer and is primarily responsible for the antiinflammatory activity.
in vitro: Cosolvents exponentially increased the solubility of both SIB and racIB, especially in the presence of PG and PEG 300. Glycerol was not very effective in increasing the aqueous solubilities of both compounds, whereas sorbitol solution had a minimal effect on their solubility. PG and PEG 300 increased the solubility of SIB by 400-fold and 1500-fold, respectively, whereas the rise in solubility for racIB was 193-fold and 700-fold, respectively, at 25 degrees C for the highest concentration of the cosolvents used (80% v/v) [1]. When (S)-(+)-IBU and (R)-(-)-IBU (1 microM) were incubated with a panel of recombinant human P450s, only CYP2C9 formed appreciable amounts of the hydroxy metabolites. At a higher IBU enantiomer concentration (500 microM), additional P450s catalyzed 2-hydroxylation (CYP3A4, CYP2C8, CYP2C19, CYP2D6, CYP2E1, and CYP2B6) and 3-hydroxylation (CYP2C19) [3].
in vivo: The presence of the CYP2C8*3 allele was found to influence the pharmacokinetics of (R)-ibuprofen in a gene-dose effect manner. Thus, after administration of 400 mg (R)-ibuprofen, the plasma half-life (95% confidence intervals) for individuals with genotypes CYP2C8*1/*1, CYP2C8*1/*3 and CYP2C8*3/*3, was 2.0 h (1.8-2.2), 4.2 h (1.9-6.5; P < 0.05) and 9.0 h (7.8-10.2; P < 0.002), respectively [2].
