Flavin adenine dinucleotide Structural

What is Flavin adenine dinucleotide?

Toxicity

Oral mouse LD50 > 7000 mg/kg. Intravenous mouse LD50 589 mg/kg.

Description

Flavin adenine dinucleotide (FAD) is a cofactor for cytochrome-b5 reductase, the enzyme that maintains hemoglobin in its functional reduced state, and for glutathione reductase. This enzyme also protects erythrocytes from oxidative damage. FAD is a redox cofactor of several essential reactions in metabolism. This cofactor exists in two redox states, with FAD and FADH2 being the oxidized and reduced forms, respectively. FAD is formed of a riboflavin moiety (vitamin B2) coupled to a phosphate group of an ADP molecule. The reaction starts with the conversion of riboflavin into flavin mononucleotide catalyzed by riboflavin kinase. Flavin mononucleotide is subsequently transformed into FAD by adding an AMP moiety from ATP catalyzed by FAD-synthase. Therefore, FAD availability is tightly dependent on vitamin B2 and energy metabolism[1].

Background

A condensation product of riboflavin and adenosine diphosphate. The coenzyme of various aerobic dehydrogenases, e.g., D-amino acid oxidase and L-amino acid oxidase. (Lehninger, Principles of Biochemistry, 1982, p972) Flavin adenine dinucleotide is approved for use in Japan under the trade name Adeflavin as an ophthalmic treatment for vitamin B2 deficiency.

Indications

Used to treat eye diseases caused by vitamin B2 deficiency, such as keratitis and blepharitis.

Definition

An adenine nucleotide containing two phosphate groups esterified to the sugar moiety at the 5′-position.

Metabolism

Not Available

Purification Methods

Small quantities of FAD are purified by paper chromatography using tert-butyl alcohol/water, cutting out the main spot and eluting with water. Larger amounts can be precipitated from water as the uranyl complex by adding a slight excess of uranyl acetate to a solution at pH 6.0, dropwise and with gentle stirring. The solution is set aside overnight in the cold, and the precipitate is centrifuged off, washed with small portions of cold EtOH, then with cold peroxide-free diethyl ether. It is dried in the dark under vacuum over P2O5 at 50-60o. The uranyl complex is suspended in water, and, after adding sufficient 0.01M NaOH to adjust the pH to 7, the precipitate of uranyl hydroxide is removed by centrifugation [Huennekens & Felton Methods Enzymol 3 954 1957]. It can also be crystallised from water. It should be kept in the dark. More recently it was purified by elution from a DEAE-cellulose (Whatman DE 23) column with 0.1M phosphate buffer pH 7, and the purity was checked by TLC.
