Abstract

Abstract In our study, three series of hydroxamate, 2-aminobenzamide, and trifluoromethyl ketone analogues have been designed and synthesized. The synthesized compounds were investigated for their in vitro antiproliferative activities using the MTT-based assay against three human cancer cell lines including A549, NCI-H661, and U937. Most analogues exhibited higher antiproliferative activities against human acute myeloid leukemia cell U937 than the other two human lung cancer cell lines. Furthermore, the compounds were examined against HDAC1, 2, and 8 isoforms. Docking study of compounds 6h, 9b, and 10a suggested that they might bind tightly to the binding pocket of HDAC2 and/or HDAC8. The results suggest that these compounds might have potential as lead compounds for the development of anti-tumor drugs with HDACs inhibitory activities.
