1. The metabolism of 1-ethylphenoxathiin-10,10-dioxide (BW1370U87), an
experimental compound designed as an inhibitor of monoamine oxidase-A
for use as a possible anti-depression agent, has been studied in a hu
man liver microsome preparation. 2. The identities of the metabolites
have been determined using directly coupled hplc-H-1 nmr at 600 MHz in
the stop-flow mode in this first study of in vitro xenobiotic metabol
ism using hplc-nmr. 3. The xenobiotic substances that were identified
comprised the parent compound BW1370U87 (with -CH2CH3 at C1) together
with sidechain-oxidized metabolites with C1 substituents of -CHOH.CH3,
-CH2.CH2OH, -CHOH.CH2OH and -CH2.COOH, plus the unsubstituted phenoxa
thiin-10,10-dioxide.
