3、1 的作弱，IC50 值 100 M；Nimesulide 具有抗炎、痛、解熱的作。IC50 & Target COX-20.07-70 M (IC50)體外研究 Nimesulide is a selective COX-2 inhibitor, with IC50s of 70 nM-70 M in a time-dependent manner, but itshows weak effect on COX-1 (IC50 100 M) 1. Nimesulide (10 M) effectively decreases VEGF inendometrium cancer cells,

4、and shows no effect on that in normal cells. Nimesulide (10 and 50 M)dramatically decreases MCP-1 levels in normal cell, and such an effect is also observed with 10 M in cancercells. In addition, Nimesulide (50 M) potently affects IL-8 level in normal cells, but causes no changes incancer cells 3.體內(nèi)

5、研究 Nimesulide (3 and 10 mg/kg, i.p.) effectively blocks fever induced by i.p. injection of LPS in rats. Nimesulide(3 mg/kg, i.p.) potently reduces fever response induced by IL-1, IL-6 or TNF-, but does not prevent theinitial rise in the febrile response induced by arachidonic acid. Nimesulide also s

6、ignificantly reduces PGE2levels and PGF2 levels in the cerebrospinal fluid of the LPS-stimulated animals, and inhibits the increase inplasma TNF- by 97% 2.PROTOCOLCell Assay 3 5105 viable cells are carefully dislodged with sterile Pasteur pipettes, transferred into new flasks andincubated with two d

7、ifferent doses of Nimesulide (10 and 50 M) for another 24 h. Incubations for differentdoses of Nimesulide are repeated three times. The culture supernatant is then collected and stored in smallaliquots at -70C until studied. VEGF, MCP-1 and IL-8 concentrations are determined by sandwichquantitative

Control animals receivethe appropriate vehicle plus saline (1 mL/200 g, i.p.). The dose of 3 mg/kg of Nimesulide is chosen for

10、 theremaining experiments. In another set of experiments, rats are pretreated with an i.p. injection of Nimesulide(3 mg/kg) or indomethacin (2 mg/kg), diluted in the appropriate vehicles, 30 min prior to an i.c.v. injection (2 L over 1 min) of IL-1 (3.12 ng), IL-6 (300 ng), TNF- (250 ng), arachidoni
