Effect of S-diclofenac, a novel hydrogen sulfide releasing derivative, on carrageenan-induced hindpaw oedema formation in the rat. European journal of pharmacology, 2007, Aug-13, Volume: 569, Issue:1-2 S-diclofenac (2-[(2,6-dichlorophenyl)amino]benzeneacetic acid 4-(3H-1,2-dithiole-3-thione-5-yl)-phenyl ester) is a novel derivative of diclofenac which, in vivo, undergoes enzymatic cleavage of its ester linkage to release hydrogen sulfide (H(2)S) along with the parent moiety, diclofenac. In this study the anti-inflammatory activity of S-diclofenac and diclofenac was studied in a carrageenan-evoked hindpaw oedema model in the rat. Drugs or vehicle were administered 3 h before carrageenan. Both drugs produced a dose-dependent anti-inflammatory effect in this model. However, S-diclofenac (ED(30), 14.2+/-0.6 micromol/kg) was more potent (P<0.05) than diclofenac (ED(30), 39.3+/-1.4 micromol/kg) as an inhibitor both of hindpaw swelling and in reducing the carrageenan-evoked rise in hindpaw myeloperoxidase activity reflecting tissue neutrophil infiltration (ED(50)s of 12.0+/-2.1 micromol/kg and 21.9+/-2.0 micromol/kg). Intraplantar carrageenan injection also significantly (P<0.05) increased hindpaw concentrations of prostaglandin E(2) (PGE(2)), nitrite/nitrate and H(2)S synthesizing activity measured at 6 h. Both S-diclofenac and diclofenac pretreatment reduced the carrageenan-induced rise in hindpaw PGE(2), nitrite/nitrate and H(2)S synthesizing activity. Whilst treatment with either drug produced similar inhibition of hindpaw PGE(2) and H(2)S synthesizing activity--S-diclofenac more effectively reduced hindpaw nitrite/nitrate concentration than did diclofenac. It is proposed that the enhanced anti-inflammatory effect of S-diclofenac relates to its ability to release H(2)S at the inflamed site.
