Phosphorus-Based SAHA Analogues as Histone Deacetylase Inhibitors
摘要:
graphicThree analogues of suberoyl anilide hydroxamic acid (SAHA) with phosphorus metal-chelating functionalities were synthesized as inhibitors of histone deacetylases (HDACs). The compounds showed weak activity for HeLa nuclear extracts (IC50 = 0.57-6.1 mM), HDAC8 (IC50 = 0.28-0.41 mM), and histone-deacetylase-like protein (HDLP, IC50 = 0.33-1.9 mM), suggesting that the transition state of HDAC is not analogous to zinc proteases. Anti proliferative activity against A2780 cancer cells (IC50 = 0.11-0.12 mM), comparable to SAHA (0.15 mM), was observed.
