Abstract: Epigenetic modulators Histone deacetylases (HDACs) and Lysine demethylase (LSD1) are validated targets for anticancer therapy. Both HDAC1/2 and LSD1 are found in association with the repressor protein CoREST in a transcriptional co-repressor complex, which is responsible for gene silencing. Combined modulation of both targets results in a synergistic antiproliferative activity. In the present investigation, we report about the design and synthesis of a series of polyamine-based HDACs-LSD1 dual binding inhibitors obtained by coupling Vorinostat and Tranylcypromine. Compound 4 emerged as the most promising of the synthesized series, showing good inhibitory activity towards HDAC1 and LSD1 either in vitro and in cell-based assay (Ki = 42.52 ± 8.94 nM and IC50 = 3.85 μM, respectively). Furthermore, at 70.0 µM compound 4 induced a more pronounced cytotoxic effect than Vorinostat (68.6% vs 56.6% of dead cells) in MCF7 cancer cell line.
