A series of sixteen ring-substituted N-arylcinnamanilides, previously described as highly antimicrobially effective against a wide spectrum of bacteria and fungi, together with two new derivatives from this group were prepared and characterized. Moreover, the molecular structure of (2E)-N-(2-bromo-5-fluorophenyl)-3-phenylprop-2-enamide as a model compound was determined using single-crystal X-ray analysis. All the compounds were tested for their anti-inflammatory potential, and most tested compounds significantly attenuated the lipopolysaccharide-induced NF-κB activation and were more potent than the parental cinnamic acid. (2E)-N-[2-Chloro-5-(trifluoromethyl)phenyl]-3-phenylprop-2-enamide, (2E)-N-(2,6-dibromophenyl)-3-phenylprop-2-enamide, and (2E)-N-(2,5-dichlorophenyl)-3-phenylprop-2-enamide demonstrated the highest inhibition effect on transcription factor NF-κB at the concentration of 2 μM and showed a similar effectiveness as the reference drug prednisone. Several compounds also decreased the level of TNF-α. Nevertheless, subsequent tests showed that the investigated compounds affect neither IκBα level nor MAPKs activity, which suggests that the N-arylcinnamanilides may have a different mode of action to prednisone. The modification of the C(2,5)0 or C(2,6)0 positions of the anilide core by rather lipophilic and bulky moieties seems to be preferable for the anti-inflammatory potential of these compounds.

Four series of acid amides were synthesized, and through measurement using a fluorogenic substrate assay with human recombinant MMP-1, MMP-2 and MMP-9, compound 3f showed considerable inhibitory activities against MMP-2, MMP-9 and the best selectivity over MMP-1. Preliminary structure-activity relationship analysis indicated that caffeic acid amides with electron-donating groups at para-position of amino phenyl group showed better inhibitory activities and selectivity than those with electron-withdrawing groups, and the presence of adjacent dihydroxy in the caffeoyl group was very important for the MMP-2 and MMP-9 inhibitory activities.
