The regioselectivity and stereoselectivity of androgen hydroxylations catalyzed by five isozymes of cytochrome P-450 purified from phenobarbital-induced rat liver were studied in a reconstituted monooxygenase system using testosterone (T) and androst-4-ene-3,17-dione (delta 4-A) as substrates. P-450 PB-3, an isozyme exhibiting low catalytic activity with(More)
7-Diethylamino-4-methylcoumarin (DEMC) is a fluorescent whitening agent (FWAs). There have been some studies on DEMC's protective effects against biological activity but there are few papers about the in vivo toxicity of DEMC. In this study, we used wild-type zebrafish embryos 3 days post fertilization (dpf). Test solutions with DEMC concentrations were(More)
