| Bioactivity | (S)-(+)-Ibuprofen ((S)-Ibuprofen), a S(+)-enantiomer of Ibuprofen, is a potent COX-1 and COX-2 inhibitor with IC50s of 2.1 μM and 1.6 μM, respectively. (S)-(+)-Ibuprofen has analgesic, anti-inflammatory, anticancer and antipyretic effects[1][2]. | ||||||||||||
| Invitro | (S)-(+)-Ibuprofen (HCT-15 and HCA-7 cells; 0-1000 µM; 8 days) treatment reduces concentration dependently cell survival in both cell lines to a similar extent[2]. (S)-(+)-Ibuprofen (HCT-15 and HCA-7 cells; 0-1000 µM; 20-72 hours) treatment causes a G0/G1 phase block as well as apoptosis[2].(S)-(+)-Ibuprofen (HCT-15 and HCA-7 cells; 900 µM; 4-72 hours) treatment shows a down regulation of cyclin A and B and an increase of the cell cycle inhibitory protein p27Kip-1[2]. (S)-(+)-Ibuprofen inhibits COX activity, thromboxane formation, and platelet aggregation[1].(S)-(+)-Ibuprofen inhibits the activation of NF-κB in response to T-cell stimulation with an IC50 of 61.7 μM[3].
