| Bioactivity | l-Naproxen ((R)-Naproxen) is an enantiomer of (S)-Naproxen. l-Naproxen can inhibit Cdc42 and Rac1 (EC50=96 μM and 212 μM, respectively), and show anti-tumor activity. l-Naproxen is a nonsteroidal antiinflammatory drug (NSAID)[1][2][3]. | ||||||||||||
| Invitro | l-Naproxen (30-1000 μM; 2 h) inhibits Rac1 and Cdc42 activity selectively in HeLa cells[3].l-Naproxen (0-300 μM; 48 h) inhibits migration of immortalized human ovarian cancer cells[3].l-Naproxen (300 μM; 48 h) shows activity via a COX-independent mechanism[3].
