Abstrakt: 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.
