The fragment of bacterial peptidoglycan muramyl dipeptide (MDP) has long been known for its adjuvant activity, however the underlying mechanism of this action has only recently been elucidated. It is ascribed to its agonist action on the nucleotide-bindin

Highly invasive tumor cells are characterized by a metabolic switch, known as the Warburg effect, from "normal" oxidative phosphorylation to increased glycolysis even under sufficiently oxygenated conditions. This dependence on glycolysis also confers a growth advantage to cells present in hypoxic regions of the tumor. One of the key enzymes involved in glycolysis, the muscle isoform of lactate dehydrogenase (LDH-A), is overexpressed by metastatic cancer cells and is linked to the vitality of tumors in hypoxia. This enzyme may be considered as a potential target for new anticancer agents, since its inhibition cuts cancer energetic and anabolic supply, thus reducing the metastatic and invasive potential of cancer cells. We have discovered new and efficient N-hydroxyindole-based inhibitors of LDH-A, which are isoform-selective (over LDH-B) and competitive with both the substrate (pyruvate) and the cofactor (NADH). The antiproliferative activity of these compounds was confirmed on a series of cancer cell lines, and they proved to be particularly effective under hypoxic conditions. Moreover, NMR experiments showed that these compounds are able to reduce the glucose-to-lactate conversion inside the cell.
