Biological Activity
| Targets | Poly(flavin adenine dinucleotide, FAD) features an additional polymer-type redox reaction and is a highly efficient electrocatalyst for NADH oxidation: at the lowest potential reported for a NADH sensor (0.00 V, pH 7.4) Working, the characteristics of poly(FAD) are: the electrochemical rate constant is 1.8±0.6×10-3 cm/s, which is at the level of NADH mass transfer constant. Poly(FAD) modified electrodes are characterized by greatly enhanced stability and are the most advantageous NADH sensors in analytical chemistry [2]. |

| ln Vivo |
Intravenous flavin adenine dinucleotide (2 mg/kg) dramatically reverses the ventricular fibrillation threshold (VFT) reduction caused by chlorpromazine (CPZ). Canine heart mitochondria are not affected by CPZ when flavin adenine dinucleotide is added. Dogs receiving a flavin adenine dinucleotide injection within 10 minutes of the administration exhibited a brief hypotension before their blood pressure returned to normal. Moreover, flavin adenine dinucleotide can stop mitochondrial dysfunction brought on by chlorpromazine [1]. In anesthetized adult mongrel dogs, prior intravenous administration of FAD (2 mg/Kg) significantly protected against chlorpromazine (CPZ, 1 mg/Kg i.v.)-induced decrease in ventricular fibrillation threshold (VFT). The VFT decreased to 56.6±5.4% of the initial level after CPZ alone, but only to 92.2±4.2% when FAD was administered before CPZ.[1] Prior administration of FAD (2 mg/Kg i.v.) also attenuated the hypotensive effect of CPZ. The drop in systolic and diastolic blood pressure 40 minutes after CPZ was significantly less severe in the FAD-pretreated group compared to the group receiving CPZ alone.[1] Heart mitochondria isolated from dogs treated with CPZ alone showed significantly decreased respiratory control index (RCI) and ADP/O. Prior administration of FAD (2 mg/Kg i.v.) partially prevented this CPZ-induced mitochondrial dysfunction, resulting in significantly higher RCI and ADP/O values compared to the CPZ-only group.[1] |
| Enzyme Assay |
Mitochondrial function assays were performed to assess the effects of FAD and CPZ. Mitochondria were isolated from the hearts of intact dogs. The respiratory control index (RCI) and ADP/O were determined using a closed assay system containing a mannitol reaction mixture, mitochondrial sample, potassium succinate, and ADP as substrates. Oxygen consumption was monitored with an oxygen electrode.[1] To assess direct in vitro effects, RCI and ADP/O were measured under three conditions using mitochondria from untreated dogs: (1) control (no drug), (2) with addition of CPZ (50 μg), and (3) with addition of FAD (100 μg) followed by CPZ (50 μg) to the reaction mixture. CPZ alone significantly decreased both RCI and ADP/O. When FAD was added before CPZ, the decreases in RCI and ADP/O were significantly attenuated, demonstrating a protective effect of FAD against CPZ-induced mitochondrial dysfunction in vitro.[1] |
| Animal Protocol |
Adult mongrel dogs (8-12 Kg) were anesthetized with intraperitoneal pentobarbital sodium (50 mg/Kg) and placed under artificial respiration. A thoracotomy was performed to expose the heart. A stimulating electrode was attached to the left ventricular apex for VFT measurement. Blood pressure was monitored via a carotid artery catheter. Femoral vein catheters were inserted for drug administration and blood sampling.[1] Dogs were divided into three groups (n=6 each). Group I (Control): received intravenous saline (2 ml/Kg), followed 10 minutes later by another saline injection (1 ml/Kg). Group II (CPZ): received intravenous saline (2 ml/Kg), followed 10 minutes later by intravenous CPZ (1 mg/Kg). Group III (FAD+CPZ): received intravenous FAD (2 mg/Kg), followed 10 minutes later by intravenous CPZ (1 mg/Kg). All solutions were administered over 1-2 minutes.[1] VFT, heart rate, and blood pressure were recorded at intervals. Blood samples were taken for serum K+ and pH measurement. Forty minutes after the first injection, the heart was isolated, and myocardial mitochondria were prepared for functional assays.[1] |
| Toxicity/Toxicokinetics |
The study reports that dogs showed a transient hypotension within 10 minutes after the intravenous injection of FAD (2 mg/Kg), after which blood pressure recovered to the initial level. No other adverse effects or toxicities of FAD were described.[1] |

| Additional Infomation |
FAD is a flavin adenine dinucleotide in which the substituent at position 10 of the flavin nucleus is a 5'-adenosyldiphosphoribityl group. It has a role as a human metabolite, an Escherichia coli metabolite, a mouse metabolite, a prosthetic group and a cofactor. It is a vitamin B2 and a flavin adenine dinucleotide. It is a conjugate acid of a FAD(3-). 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. Flavin adenine dinucleotide has been reported in Eremothecium ashbyi, Drosophila melanogaster, and other organisms with data available. FAD is a metabolite found in or produced by Saccharomyces cerevisiae. 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) See also: ... View More ... Drug Indication Used to treat eye diseases caused by vitamin B2 deficiency, such as keratitis and blepharitis. Flavin Adenine Dinucleotide (FAD) was investigated based on prior in vitro findings that it specifically combines with chlorpromazine (CPZ).[1] The study suggests that the arrhythmogenic and hypotensive actions of CPZ might be associated, at least in part, with impaired mitochondrial function. FAD is proposed to protect against these effects by competitively binding with CPZ, given the structural similarity between the two molecules, thereby preventing CPZ from inhibiting mitochondrial flavin-containing enzymes and other components.[1] The authors propose that FAD might be useful in the treatment of cardiac disturbances associated with overdosage of CPZ.[1] |
