In Vitro | In vitro activity: Ketoprofen combined with UVB irradiation induces the cytotoxicity and suppresses DNA synthesis in HaCaT cells in a concentration-dependent manner. Ketoprofen combined with UVB irradiation inhibits the cell growth and induces G2/M cell cycle arrest by modulating the levels of cdc2, cyclin B1, Chk1, Tyr15-phosphorylated cdc2 and p21. Ketoprofen combined with UVB irradiation also provokes a striking accumulation of cyclin B1-cdc2-p21 complexes, concomitantly with an increase in the levels of Tyr15-phosphorylated cdc2 and p21 protein. Ketoprofen combined with UVB irradiation accentuates the apoptotic response to UVB radiation in HaCaT cells as evidenced by DAPI staining.
Kinase Assay: Ketoprofen (RP-19583) is a non-steroidal antiinflammatory agent, acting as a potent inhibitor of COX, with IC50s of 2 nM and 26 nM for COX-1 and COX-2 in human blood monocytes, respectively. |

Formulation & Dosage | Ketoprofen (RP-19583) (0.1-1.0 mg/kg) and morphine (0.1-1.0 mg/kg) are evaluated for their effectiveness to block U69,593-induced depression of nesting. For these studies, Ketoprofen (RP-19583) or morphine is administered 30 min before nesting, 1.0 mg/kg U69,593 is administered 15 min before nesting, and each set of conditions is tested in a group of six mice. |
