In vitro screening of the effect of hydrazine derivatives on hepatic aryl hydrocarbon hydroxylase activity.
1. The effect of hydrazine derivatives on the in vitro hepatic microsomal aryl hydrocarbon hydroxylase activity was examined using Sprague-Dawley male rats. 2. All hydrazine derivatives examined have some degree of inhibition on hepatic aryl hydrocarbon hydroxylase activity. 3. The inhibitory effect is concentration dependent and is also dependent on the structural substitution of the hydrazines. The more lipophilic the derivative, the more potent the inhibition of aryl hydrocarbon hydroxylase activity.
