Intracellular Trapping of the Selective Phosphoglycerate Dehydrogenase (PHGDH) Inhibitor BI-4924 Disrupts Serine Biosynthesis
摘要:
Phosphoglycerate dehydrogenase (PHGDH) is known to be the rate-limiting enzyme in the serine synthesis pathway in humans. It converts glycolysis-derived 3-phosphoglycerate to 3-phosphopyruvate in a co-factor-dependent oxidation reaction. Herein, we report the discovery of BI-4916, a prodrug of the co-factor nicotinamide adenine dinucleotide (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, a subsequent hit optimization using structure-based drug design was conducted to deliver a single-digit nanomolar lead series and to improve potency by 6 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(+).

The invention relates to the use, as active principle, in a physiologically acceptable medium, in a composition, of an effective amount of at least one compound of the indolecarboxylic family, this compound or these compositions being intended to treat disorders associated with overactivity of 5&agr;-reductase. These compounds or the compositions containing them are more particularly intended to treat androgen-dependent disorders such as seborrhoea and/or acne and/or hirsutism and/or androgenic alopecia. The invention also relates to novel compounds of the indolecarboxylic family and to compositions containing them.
