Queuine (dihydrochloride)

Queuine dihydrochloride is a selective substrate for tRNA guanine transglycosylase (TGT) and can be incorporated into eukaryotic tRNA. Queuine dihydrochloride promotes tRNA modification, affecting mitochondrial function and Warburg metabolic phenotype. If Queuine dihydrochloride is deficient, aerobic glycolysis can be enhanced, oxidative phosphorylation can be inhibited, and Warburg metabolism can be promoted, accompanied by increased ammonia and lactate production and increased lactate dehydrogenase activity. Queuine dihydrochloride can be used for autoimmune diseases (such as experimental models of multiple sclerosis) and cancer metabolic regulation, and its deficiency is associated with low tRNA modification in tumor cells[1][2][3].
