A potent mutagen was isolated from a pyrolysate of L-ornithine. The mutagenic activity of this compound on Salmonella typhimurium TA 98 was 28400 revertants/0.5 μg. This compound was deduced to be 4-amino-6-methyl-1H-2, 5, 10, 10b-tetraazafluoranthene by X-ray crystallographic analysis.
从 L-鸟氨酸的热解产物中分离出一种有效的诱变剂。该化合物对鼠伤寒沙门氏菌 TA 98 的诱变活性为 28400 个回复突变体/0.5 μg。通过X射线晶体分析,该化合物推断为4-氨基-6-甲基-1H-2,5,10,10b-四氮杂荧蒽。
