Synthesis and Modeling of New Benzofuranone Histone Deacetylase Inhibitors that Stimulate Tumor Suppressor Gene Expression

摘要

New benzofuranones were synthesized and evaluated toward NCI-H661 non-small cell lung cancer cells. Benzamide derivatives possessed micromolar anti proliferative and histone deacetylase inhibitory activities and modulate histone H4 acetylation. Hydroxamic acids were found to be potent nanomolar anti proliferative agents and HDAC inhibitors. Computational analysis presented a rationale for the activities of the hydroxamate derivatives. Impact of the HDAC inhibition on the expression of E-cadherin and the SEMA3F tumor suppressor genes revealed new promising compounds for lung cancer treatments.
