Ketoprofen

Ketoprofen is a non-selective NSAID with IC50 of 0.5 μM and 2.33 μM for human recombinant COX-1 and COX-2, respectively.(In Vitro):Ketoprofen inhibits COX in LPS-stimulated monocytes isolated from human blood, with IC50 values of 2 nM (COX-1) and 26 nM (COX-2).Ketoprofen (2.5 mg /mL, 3-24h) decreases the mRNA level of immune factors (TNFα, IL-8, SAA and COX-2) and PTGES in LPS-stimulated bovine mammary epithelial cells.\n(In Vivo):Ketoprofen (Oral administration, 10 mg/kg, three times a week for 10 weeks, HFD-induced obese C57BL/6 mice) decreases in relative body weight (15.41%), the iWAT mass (approximately 41%), and leptin (58.68%) and resistin (12.88%).Ketoprofen (50 mg/kg, LPS-treated dairy cows) lowers the increase of somatic cell count (SCC), serum albumin (SA), IgG and lactate dehydrogenase (LDH) activity in milk induced by LPS.
