DNS-pE
DNS-pE is a 3-phosphoglycerate dehydrogenase (PHGDH) inhibitor with a Ki of 7.4 μM. DNS-pE selectively and irreversibly covalently modifies endogenous PHGDH in live mammalian cells, its vinyl sulfone moiety acts as a fluorescence quencher that becomes highly fluorescent upon covalent modification of PHGDH. DNS-pE can be used as a fluorescent dye for live-cell imaging.

Biological Activity
DNS-pE (10 μM; 1 h) shows robust fluorescence Turn-ON activity with cysteine, achieving a 21-fold increase in fluorescence after 1 h of incubation at room temperature[1].
DNS-pE (1-50 μM; 3 h) concentration-dependently compets with a clickable IA probe for binding to endogenous PHGDH in live MCF-7 cells[1].
