Design, synthesis and anticancer activity of novel valproic acid conjugates with improved histone deacetylase (HDAC) inhibitory activity
Twenty-five valproic acid conjugates have been designed and synthesized. All target compounds were explored for their in vitro anti-proliferative activities using the MTT-based assay against four human cancer cell lines includingliver (HePG2), colon (HCT116), breast (MCF7) and cervical (HeLa) carcinoma cell lines. Out of six valproic acid-amino acid conjugates 2a-f. Only cysteine containing conjugate 2f showed the significant activity (IC50 ... Read more
