| Hazard Information | Back Directory | [Description]
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).1 L-Biopterin is rarely found under physiological conditions except in the epidermis of patients with the depigmentation disorder Vitiligo.2 | [Chemical Properties]
Crystalline Solid | [Uses]
6-Biopterin is an oxidation product from the melanogenesis regulating cofactor (6R)5,6,7,8 tetrahydrobiopterin (6-BH4). In vitro, 6-Biopterin is cytotoxic to melanocytes. However, in vivo, 6-Biopterin is rapidly and sequentially reduced back to 6-GH4 via q-BH2. Recent studies suggest that 6-Biopterin among other pteridines may be a useful non-invasive biomarker for cancer. | [Uses]

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. | [Application]

Recent studies suggest that 6-Biopterin among other pteridines may be a useful non-invasive biomarker for cancer. | [Preparation]
Biopterin is synthesized by reacting 2,4,5-triamino-6-hydroxypyrimidine with 5-deoxy-L-arabinosone in aqueous solution at pH of about 7.5 to 10, acidifying and then recrystallizing by dissolving in basic solution and precipitating with acid. 5-deoxy-L-arabinosone is prepared by oxidizing S-deoxy-L-arabinose, which is prepared from L-rhamnose, using cupric acetate.
Process for the synthesis of biopterin | [Safety Profile]
Moderately toxic by ingestion andintraperitoneal routes. Mutation data reported. Whenheated to decomposition it emits toxic vapors of NOx. |
