The HDAC inhibitor 4-tert-butyl-N-(4-(hydroxycarbamoyl)phenyl)benzamide (AES-350, 51) was identified as a promising preclinical candidate for the treatment of acute myeloid leukemia (AML), an aggressive malignancy with a meagre 24% 5-year survival rate. Through screening of low-molecular-weight analogues derived from the previously discovered novel HDAC inhibitor, AES-135, compound 51 demonstrated greater HDAC isoform selectivity, higher cytotoxicity in MV4-11 cells, an improved therapeutic window, and more efficient absorption through cellular and lipid membranes. Compound 51 also demonstrated improved oral bioavailability compared to SAHA in mouse models. A broad spectrum of experiments, including FACS, ELISA, and Western blotting, were performed to support our hypothesis that 51 dose-dependently triggers apoptosis in AML cells through HDAC inhibition.

Histone deacetylases (HDACs) regulate many important physiological processes and the discovery of small molecules that modulate HDAC activity has both academic and clinical relevance. HDAC inhibitors, most notably SAHA, have been pursued as cancer chemotherapeutics but may be useful in treating psychiatric disorders, malaria, and other diseases. Herein, we describe an inexpensive and robust assay, based on fluorescence polarization, for HDAC ligand discovery. The assay is well suited for high-throughput screening and enzyme kinetic studies.
