Abstract
Phytochemical study of Calea prunifolia HBK identified two compounds derived from p-hydroxyacetophenone, the 1-(2-hydroxy-5-(1-methoxyethyl)phenyl)-3-methylbut-2 -en-1-one showed a satisfactory anti-inflammatory activity (58.33%), when considering that this is a natural product. Although the two derived compounds are structurally similar, the anti-inflammatory activity of 1-(2-hydroxy-5-methoxyphenyl)-3-methylbut-2-en-1-one was not significant (2.08%). The test was conducted in a model of inflammation induced by topical application of 12-O-tetradecanoylphorbol-13-acetate (TPA) in the ear of mice. The positive control was tested with indomethacin and the negative control was done only with vehicle. These results allow the identification of a pharmacophore group that through molecular modeling studies and organic synthesis can result in compounds with improved anti-inflammatory activity.
