title: [In vitro metabolism of 4-benzylisoquinolines, analogs of papaverine].
abstract: A comparative study was made on sliced Rat liver of the in vitro disappearance of papaverine, PV 2 6,7-dimethoxy-4-(parachlorobenzyl)isoquinoline and its mono and di isopropoxy derivatives. Data show that papaverine and PV 2 are equally sensitive to oxygenases, although 7 mono and 6,7 di-isopropoxy derivatives are much less so, being more bulky and undergo in enzymic O-dealkylation less easily. The data also show that PV 2 and 6-isopropoxy desmethoxy PV 2 disappear at the same rate, more readily than the 7 isopropoxy isomer. This confirms the in vivo results previously reported. The antispasmodic in vitro activity of these compounds is reported.
