黄素腺嘌呤二核苷酸(英语:FAD),又称活性型维生素B2、核黄素-5'-腺苷二磷酸,是一种参与了重要的代谢反应的氧化还原辅酶。FAD是一种比NAD和NADP更强的氧化剂,能被1个电子或2个电子途径还原。其可用于标记黄嘌呤腺嘌呤氧化酶,核黄素激酶肿瘤坏死因子受体1 NADPH氧化酶。
Human Endogenous Metabolite
Poly(Flavin adenine dinucleotide, FAD) characterized by an additional polymer-type redox reaction is a highly effective electrocatalyst for NADH oxidation: operating at the lowest potentials reported for NADH transducers (0.00 V, pH 7.4), poly(FAD) is characterized by the electrochemical rate constant of 1.8 ± 0.6×10 -3 cm/s, which is at the level of the NADH mass-transfer constant. Poly(FAD)-modified electrodes are characterized by the dramatically improved stability and, is the most advantageous NADH transducers for analytical chemistry.
Flavin adenine dinucleotide (2 mg/kg, i.v.) significantly cancels chlorpromazine (CPZ)-induced decrease in ventricular fibrillation threshold (VFT). Flavin adenine dinucleotide cancels the effect of CPZ on canine heart mitochondria. After injection of Flavin adenine dinucleotide, the dogs show a transient hypotension within 10 min, then their blood pressures recover to the initial level. Flavin adenine dinucleotide also prevents mitochondrial dysfunction induced by chlorpromazine.
