Bayer 39007 (o-Isopropoxyphenyl N-methylcarbamate) 
Incubation of Bayer 39007 with rat liver microsomes gave rise to about 
seven metabolites. Of these, one was identified as o-isopropoxyphenyl N- 
hydroxymethylcarbamate; another may be the p-hydroxyl analog of Bayer 39007; 
and the others remain unidentified. Similar results were obtained by exposing 
this compound to roaches and houseflies. When fed to humans, Bayer 39007 
was recovered from urine almost quantitatively as o-isopropoxyphenol, 
probably excreted as the glucuronide (Dawson et al., 1964). 
Plants apparently converted Bayer 39007 into a water-soluble fraction 
which has not been identified (Dorough and Casida, 1964).
