Descrição geral

SAICAR is an intermediate in purine metabolism. SAICAR is converted from 5-amino-1-(5-phospho-D-ribosyl) imidazole-4-carboxylate (CAIR, Carboxy-AIR, carboxyaminoimidazole ribotide; CAS 6001-14-5) by phosphoribosylaminoimidazole-succinocarboxamide synthase (SAICAR synthase). SAICAR (a ribotide) can lose its phosphate group leading to the appearance of a riboside known as succinylaminoimidazolecarboxamide riboside (SAICAriboside or SAICAr) in cerebrospinal fluid, in urine, and, to a lesser extent, in plasma. When present in sufficiently high levels, SAICAR can act as an oncometabolite, where it promotes tumour growth & survival under glucose-limited conditions by stimulating pyruvate kinase isoform M2 (PKM2) and promoting aerobic glycolysis.

Human pyruvate kinase isoform M2 (PKM2) is a glycolytic enzyme isoform implicated in cancer. Malignant cancer cells have higher levels of dimeric PKM2, which is regarded as an inactive form of tetrameric pyruvate kinase. This perceived inactivity has fueled controversy

Purine homeostasis is ensured through a metabolic network widely conserved from prokaryotes to humans. Purines can either be synthesized de novo, reused, or produced by interconversion of extant metabolites using the so-called recycling pathway. Although thoroughly characterized in microorganisms, such

Pyruvate kinase isoform M2 (PKM2) plays an important role in the growth and metabolic reprogramming of cancer cells in stress conditions. Here, we report that SAICAR (succinylaminoimidazolecarboxamide ribose-5'-phosphate, an intermediate of the de novo purine nucleotide synthesis pathway) specifically stimulates
