Photochemistry of dihydrobiopterin in aqueous solution

Dihydrobiopterin (H2Bip) and its oxidized analogue, biopterin (Bip), accumulate in the skin of patients suffering from vitiligo, a chronic depigmentation disorder in which the protection against UV radiation fails. The photochemistry of H2Bip was studied in neutral aqueous solutions upon UV-A irradi...
