The potential as a cancer therapeutic target of the recently reported hotspot binding region close to Lys508 of the β-catenin armadillo repeat domain was not exhaustively explored. In order to get more insight, we synthesized novel -(heterocyclylphenyl)benzenesulfonamides -. The new compounds significantly inhibited Wnt-dependent transcription as well as SW480 and HCT116 cancer cell proliferation.

Despite intensive efforts, no inhibitors of the Wnt/β-catenin signaling pathway have been approved so far for the clinical treatment of cancer. We synthesized novel -(heterocyclylphenyl)benzenesulfonamides as β-catenin inhibitors. Compounds - showed strong inhibition of the luciferase activity.

Most cancer cells switch their metabolism from mitochondrial oxidative phosphorylation to aerobic glycolysis to generate ATP and precursors for the biosynthesis of key macromolecules. The aerobic conversion of pyruvate to lactate, coupled to oxidation of the nicotinamide cofactor, is a primary hallmark of cancer and is catalyzed by lactate dehydrogenase (LDH), a central effector of this pathological reprogrammed metabolism. Hence, inhibition of LDH is a potential new promising therapeutic approach for cancer.
