It is characterized by congenital microcephaly, psychomotor retardation, and seizures. Function SERA_HUMAN Publication Abstract from PubMed Phosphoglycerate dehydrogenase (PHGDH) is known to be the rate limiting enzyme in the serine synthesis pathway (SSP) in humans. It converts glycolysis derived 3-phosphoglycerate to 3-phosphopyruvate in a NADH/NAD(+)-dependent oxidation reaction. Herein we report the discovery of BI-4916, a prodrug of the NADH/NAD(+)-competitive PHGDH inhibitor BI-4924 which has shown high selectivity against the majority of other dehydrogenase targets. Starting with a fragment-based screening (FBS) a subsequent hit optimization using structure based drug design (SBDD) was conducted to deliver a single digit nanomolar lead series and to improve potency by six orders of magnitude. To this end, an intracellular ester cleavage mechanism of the ester prodrug was utilized to achieve intracellular enrichment of the actual carboxylic acid based drug and thus overcome high cytosolic levels of the competitive cofactors NADH/NAD(+).
