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.

Catalytic ring‐opening of bio‐sourced non‐strained lactones with aromatic amines can offer a straightforward, 100 % atom‐economical, and sustainable pathway towards relevant N‐aryl amide scaffolds. Herein, the first general, metal‐free, and highly efficient N‐aryl amide formation is reported from poorly reactive aromatic amines and non‐strained lactones under mild operating conditions using an organic
