A new mutagen, 2-amino-1, 7, 9-trimethylimidazo[4, 5-g]quinoxaline (1), isolated from beef extract, was synthesized from 3-fluoro-2-methylaniline via an intermediate, 2, 8-dimethyl-7-methylaminoquinoxaline (7a). Its 2-methylanalog (2) was also synthesized from the same intermediate. The synthetic 1 showed the same mutagenic activity as the isolated mutagen. However, 2 was non-mutagenic.
从牛肉提取物中分离出一种新的诱变剂--2-氨基-1,7,9-三甲基咪唑并[4,5-g]喹喔啉(1),由 3-氟-2-甲基苯胺通过中间体 2,8-二甲基-7-甲基氨基喹喔啉(7a)合成。它的 2-甲基类似物(2)也是由同一中间体合成的。合成的 1 具有与分离出的诱变剂相同的诱变活性。然而,2 并不诱变。
