Biochem/physiol Actions

NCT-503 is an inhibitor of phosphoglycerate dehydrogenase (PHGDH), which catalyzes the first, rate-limiting step of glucose-derived serine synthesis. NCT-503 reduced glucose-derived serine production and suppressed the growth of both PHGDH-dependent cancer cells in culture and in xenograft tumors, and caused G1/S cell cycle arrest in MDA-MB-468 cells. NCT-503 reduced the incorporation of one-carbon units from glucose-derived and exogenous serine into nucleotides, which may contribute to its anticancer activity. NCT-503 had an IC50 value of 2.5 μM for PHGDH and was inactive against a panel of other dehydrogenases and minimal cross-reactivity in a panel of 168 G-protein-coupled receptors (GPCRs). NCT-503 was found to be noncompetitive with respect to both 3-PG and NAD+, and exhibit good stability (>98% after 48 hrs in assay buffer) and aqueous solubility.

The small-molecule inhibitor of phosphoglycerate dehydrogenase, NCT-503, reduces incorporation of glucose-derived carbons into serine in vitro. Here we describe an off-target effect of NCT-503 in neuroblastoma cell lines expressing divergent phosphoglycerate dehydrogenase (PHGDH) levels and single-cell clones with CRISPR-Cas9-directed PHGDH

Metabolic rewiring is a hallmark of cancer that supports tumor growth, survival, and chemotherapy resistance. Although normal cells often rely on extracellular serine and glycine supply, a significant subset of cancers becomes addicted to intracellular serine/glycine synthesis, offering an attractive
