| Abstract: | The metabolism of 2-bromoethylaminonaphthoquinone in hepatocytes isolated from rats was studied. This compound was chemically inert in the reaction system used. However, in buffer solution containing isolated hepatocytes, it was gradually converted into aziridinylnaphthoquinone. Under the same reaction conditions, 4-chlorobutylaminonaphthoquinone also gave the cyclization products, pyrrolidinylnaphthoquinone. Cellular GSH decreased in both reactions. |
