Dichloroacetophenone is a pyruvate dehydrogenase kinase 1 (PDK1) inhibitor with suboptimal kinase selectivity. Herein, we report the synthesis and biological evaluation of a series of novel dichloroacetophenones. Structure-activity relationship analyses (SARs) enabled us to identify three potent compounds, namely 54, 55, and 64, which inhibited PDK1 function, activated pyruvate dehydrogenase complex, and reduced the proliferation of NCI-H1975 cells. Mitochondrial bioenergetics assay suggested that 54, 55, and 64 enhanced the oxidative phosphorylation in cancer cells, which might contribute to the observed anti-proliferation effects. Collectively, these results suggested that 54, 55, and 64 could be promising compounds for the development of potent PDK1 inhibitors.

An approach to the dichlorinative deamidation of primary β-ketoamides through ketonic cleavage is described, and a series of α,α-dichloroketones were furnished mostly in the presence of TEMPO. Based on control experiments, a mechanism involving tandem dichlorination and deamidation is proposed to interpret the observed reactivity.
