Application

NCT-503 Inactive Control has been used as a small molecule inhibitor of phosphoglycerate dehydrogenase in neuroblastoma cells.

Biochem/physiol Actions

NCT-503 Inactive Control is the inactive control probe for NCT-503, which is an inhibitor of phosphoglycerate dehydrogenase (PHGDH), the enzyme that catalyzes the first, rate-limiting step of glucose-derived serine synthesis. NCT-503 Inactive Control has an IC50 value >57 μM for PHGDH. NCT-503 has an IC50 value of 2.5 μM for PHGDH. NCT-503 Inactive Control is water soluble and has good stability, similar to NCT-503.

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

MYCN amplification drives the development of neuronal cancers in children and adults. Given the challenge in therapeutically targeting MYCN directly, we searched for MYCN-activated metabolic pathways as potential drug targets. Here we report that neuroblastoma cells with MYCN amplification show
