General description

Phenylarsine oxide (PhAsO4) is a bifunctional SH group chemical. It is hydrophobic in nature.

Application

Phenylarsine oxide has been used to infuse animals with a nigrostriatal transection, to determine whether peroxovanadium (pVa) would synergize with brain-derived neurotrophic factor (BDNF).

Biochem/physiol Actions

Phenylarsine oxide (PAO) can reduce the motility and sustainability of Setaria cervi. It has the ability to stimulate cyclosporin A-sensitive transition in the presence of EGTA (ethylene glycol-bis(β-aminoethyl ether)-N,N,N′,N′-tetraacetic acid). It acts as a stimulator of mitochondrial ion fluxes.
Phenylarsine oxide inhibits internalization of cell surface receptors; inhibits tyrosine phosphatases, with no effect on tyrosine kinase. Metabolic poison.
