Inhibition of historic deacetylases (HDACs) leads to growth arrest, differentiation, or apoptosis or tumor cell lines, Suggesting HDACs as promising targets for cancer therapy. At present, only one HDAC inhibitor (HDACi) is used in therapy: suberoylanilide hydroxamic acid (SAHA). Here, we describe the synthesis and biological evaluation of a new series of compounds derived from SAHA by Substituting Short alkyl chains at various positions of the phenyl ring. Such modifications induced variable effects ranging from partial loss of activity to increased potency. Through molecular modeling, we describe a possible interaction between HDAC7 proline 809, a residue that is strictly conserved within class 2 enzymes only, and the amide group of HDACi, while nuclear magnetic resonance experiments indicated that dimethyl m-substitution may stabilize the inhibitor in the active site. Our data provide novel information on the structure-activity relationship of HDACi and suggest new ways for developing second generation SAHA-like molecules.
