Dimethoxy- and trimethoxychalcone derivatives, with various patterns of fluorination, were synthesized and evaluated for their influence on nitric oxide production. Some of them, chalcones 1, 5, 7, 10, 11 and 17, inhibited NO production with an IC50 in the submicromolar range; 17 is especially noteworthy because of its potency (IC50 30 nM). These effects were not the consequence of a direct inhibitory action on enzyme activity but the inhibition of enzyme expression. (C) 2002 Elsevier Science Ltd. All rights reserved.

A new series of 1-(4-aminosulfonylphenyl)-3,5-diaryl pyrazolines (5) was synthesized by the reaction of appropriate chalcones 3 with 4-hydrazinobenzenesulfonamide hydrochloride (4) in ethanol in the presence of catalytic amount of acetic acid. All newly synthesized compounds were in vivo evaluated for their antiinflammatory activity using carrageenan-induced rat paw edema assay. Five of the newly synthesized
