Monoamine Oxidase
MAO
Monoamine oxidases (MAO) are a family of enzymes that catalyze the oxidation of monoamines. They are found bound to the outer membrane of mitochondria in most cell types in the body. They belong to the protein family of flavin-containing amine oxidoreductases. Monoamine oxidases catalyze the oxidative deamination of monoamines. Oxygen is used to remove an amine group from a molecule, resulting in the corresponding aldehyde and ammonia. Monoamine oxidases contain the covalently bound cofactor FAD and are, thus, classified as flavoproteins. Because of the vital role that MAOs play in the inactivation of neurotransmitters, MAO dysfunction is thought to be responsible for a number of psychiatric and neurological disorders. MAO-A inhibitors act as antidepressant and antianxiety agents, whereas MAO-B inhibitors are used alone or in combination to treat Alzheimer’sand Parkinson’s diseases.

Triphenyl phosphate-d15
0 ImagesSynonyms: Celluflex TPP-d15; DHPF 005-d15; Disflamol TP-d15; Disflamoll TP-d15; NSC 57868-d15; Phenyl phosphate ((PhO)3PO)-d15; Phoscon FR 903N-d15Triphenyl phosphate-d15 is the deuterium labeled Triphenyl phosphate. Triphenyl phosphate is an orally active, blood-brain barrier-permeable aryl organophosphate flame retardant and endocrine disruptor. Triphenyl phosphate disrupts mitochondrial dynamic balance through oxidative stress, induces excessive mitophagy and apoptosis, and ultimately leads to myocardial fibrosis. In the brain, Triphenyl phosphate activates the NF-κB inflammatory pathway by disrupting the gut microbiota, alters tryptophan metabolism and elevates neurotoxins, thereby inducing anxiety- and depression-like behaviors. In the skeletal and reproductive systems, Triphenyl phosphate inhibits osteoblast differentiation and induces germ cell apoptosis by suppressing the MAPK/ERK pathway and activating the JNK signal, respectively. In adipose and placental tissues, Triphenyl phosphate promotes lipid accumulation by activating the PI3K/AKT-PPARγ axis, and disrupts placental metabolism via the MAOA/ROS/NF-κB cascade, impairing neurodevelopment of offspring.
