Abstract
Allylisopropylacetamide caused a decrease in the level of chick embryo liver cytochrome P-450 1 h after administration, followed by an elevation above control levels at a later time period. Propylisopropylacetamide on the other hand did not produce an early decrease in cytochrome P-450 but produced an elevation of cytochrome P-450 at a later time period. Since propylisopropylacetamide is an inducer of δ-aminolevulinic acid synthetase activity and porphyrin accumulation in chick embryo liver, it was concluded that a loss of cytochrome P-450 is not a prerequisite for ALA-synthetase induction as is thought to be the case in rats.
