Chronic phenobarbitone administration inhibits the apo-(tryptophan pyrrolase) activity in homogenates of rat liver and subsequent withdrawal enhances the enzyme activity by 2.5-fold. Similar effects have been previously produced by chronic ethanol administration and withdrawal, but, whereas NADH may cause the ethanol inhibition, that by phenobarbitone may be mediated by NADPH.
长期给予苯巴比妥会抑制大鼠肝脏匀浆中脱辅基(色氨酸吡咯酶)的活性,随后停药会使该酶活性增强2.5倍。慢性给予乙醇并随后停药此前也产生过类似效果,但是,虽然还原型辅酶Ⅰ(NADH)可能导致乙醇抑制作用,但苯巴比妥的抑制作用可能由还原型辅酶Ⅱ(NADPH)介导。
