  Quinazolin-4-one Derivatives as Selective Histone Deacetylase-6 Inhibitors for the Treatment of Alzheimer’s Disease

  摘要：

  Novel quinazolin-4-one derivatives containing a hydroxamic acid moiety were designed and synthesized. All compounds were subjected to histone deacetylase (HDAC) enzymatic assays to identify selective HDAC6 inhibitors with nanomolar IC50 values. (E)-3-(2-Ethyl-7-fluoro-4-oxo-3-phenethyl-3,4-dihydroquinazolin-6-yl)-N-hydroxyacrylamide, 4h, NHis the most potent HDAC6 inhibitor (IC50, 8 nM). In vitro, these compounds induced neurite outgrowth accompanied by growth-associated protein 43 expression, and they enhanced the synaptic activities of PC12 and SH-SY5Y neuronal cells without producing toxic or mitogenic effects. Several of the compounds dramatically increased nonhistone protein acetylation, specifically of g-tubulin. Some of the more potent HDAC6 inhibitors decreased zinc-mediated beta-amyloid aggregation in vitro. N-Hydroxy-3-(2-methyl-4-oxo-3-phenethyl-3,4-dihydroquinazolin-7-yl)-acrylarnide, 3f, the most promising drug candidate, selectively inhibits HDAC6 (IC50,29 nM), practically does not affect human ether-a-go-go-related membrane channel activity (IC50 >10 mu M) or cytochrome P450 activity (IC50 >63 mu M) in vitro, and significantly improves learning-based performances of mice with beta-amyloid-induced hippocampal lesions.
