title: Anticancer activity and quantitative-structure activity relationship (QSAR) studies of a series of antioxidant/anti-inflammatory aryl-acetic and hydroxamic acids.
abstract: A series of aryl-acetic acids and hydroxamic acids possessing antioxidant/anti-inflammatory activities were tested for anticancer activity using different cancer cell lines. The compounds have low antitumor activity considering the 1/IC(50) values attained for the cell lines. Compound 5iv presents the best anticancer activity. Moreover, they depict the same activity pattern, suggesting similar mechanisms of action correlated to their antioxidant activities. The obtained results subjected in a QSAR analysis. It seems reasonable to conclude that the same molecular structural features are responsible for the compounds biological activity, these being the electron accepting/donating ability and the molar volume. For all cellular lines (HT-29, A-549 and OAW-42) log 1/IC(50) exhibits a reasonable correlation with a two parameters relationship in which the Esp-min and D term are present. Apart from Esp-min the other descriptor found important for anticancer activity is the molar volume (MgVol). The QSAR analyses did not indicate any role for lipophilicity Electrostatic potential, dipole moment and the bulk, primarily affect the biological response.
