Definition

ChEBI: An arsine oxide derived from phenylarsine.

General Description

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

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.

Safety Profile

Poison by intravenous and intraperitoneal routes. When heated to decomposition it emits toxic fumes of As. See also ARSENIC COMPOUNDS
