Description and Uses
6-Biopterin (L-Biopterin) is the oxidized form of tetrahydro-L-biopterin (BH4), a nitric oxide synthase (NOS) cofactor. L-Biopterin can be reduced to BH4 via thioredoxin reductase followed by dihydropteridine reductase or reduced glutathione. It is extremely toxic to human melanocytes in culture (IC50 = 0.2 μM after 48 hrs). L-Biopterin is rarely found under physiological conditions except in the epidermis of patients with the depigmentation disorder Vitiligo.
L-Biopterin is a pteridine widely distributed in nature; naturally occurring as the L-erythro-form. Considered as a growth factor for some insects. Fluoresces with a blue color in alkaline solution.
