Notes: Hypoxanthine-d4 is intended for use as an internal standard for the quantification of hypoxanthine (Item No. 22254) by GC- or LC-MS. Hypoxanthine is an endogenous purine derivative and the major purine involved in the purine salvage pathway in the brain.{39146} Intrastriatal administration of hypoxanthine (10 µM) increases mitochondrial complex II, also known as succinate dehydrogenase, activity and decreases cytochrome c oxidase activity, resulting in neuroenergetic impairment, ATP depletion, and cellular apoptosis in rats. Hypoxanthine also induces hyperuricemia in mice.{39147} Spinal fluid levels of hypoxanthine are increased in patients with Lesh-Nyhan syndrome, an inborn error of metabolism characterized by cognitive deficits, motor dysunction, self-mutilation, and hyperuricemia.
