2-(2-Methylphenoxy)-2H,4H-1,3,2lambda~5~-benzodioxaphosphinin-2-one

VerwendenPlasma carboxylic-ester hydrolase (EC3.1.1.1) is a very important detoxification route for the toxic stereoisomers of soman. Detoxification is meant in the sense that if soman was bound to carbox-ylic-ester hydrolase, it was not free to inhibit acetylcholinesterase. CBDP (2-(2-Methylphenoxy)-4H-1,3,2-benzodioxaphosphorin 2-oxide) pretreatment, which inhibited irreversibly carboxylic-ester hydrolase activity without inhibiting phosphoryl phosphatase activity, potentiated the toxicity of soman in mice. In toxicity experiments, CBDP (0.5 mg/kg; iv 1 hr prior to soman) pretreatment potentiated the toxicity of C(±)P(±)-, C(+)P()-, and C()P()-soman to a similar degree[1].
