Resminostat, also known as RAS2410, is a potent inhibitor of histone deacetylase (HDAC) classes I and II (including HDAC1, HDAC3 and HDAC6) with 50% inhibition concentration IC50 values ranging from 43 to 72 nmol/L. Resminostate has the potential to be used for the treatment of multiple myeloma (MM) due to its ability to induce histone H4 hyperacetylation, and apoptosis (IC50 ranging from 2.5 to 3 μmol/L) in MM cells. Recent study results have shown that, in MM cell lines, resminostat abrogates cell growth, suppresses proliferation and induce G0/G1 cell cycle arrest as well as interfering with Akt signaling pathway by decreasing phosphorylation of 4E-BP1 and p70S6k.
