(6R)-5,6,7,8-Tetrahydrobiopterin dihydrochloride,

Application

(6R)-BH₄ has been used as a buffer component for assaying tyrosine hydroxylase enzyme activity in mouse brain tissues. (6R)-BH₄ has also been identified as an activator compound from a LOPAC library screen using a fluorogenic α-glucosidase assay.

Biochem/physiol Actions

Lack of tetrahydrobiopterin may cause hyperphenylalaninemia. Diseases like, Parkinson′s, autism, depression and Alzheimer′s shows low concentration of tetrahydrobiopterin in the cerebrospinal fluid. This coenzyme participates in dopamine (DA) synthesis.
