One fluorescent compound previously named TDP-2 was isolated and purified from a rice culture of Fusarium equiseti (Alaska 2-2). Mass spectral and nuclear magnetic resonance data indicated that it is a C-3'-N-acetyl derivative of fusarochromanone, a newly discovered mycotoxin. Time course studies of synthesis of these two compounds on autoclaved rice and Czapek-Dox medium enriched with soybean peptone indicated that fusarochromanone was converted to TDP-2 in the cultures. A high concentration of peptone in the liquid medium may stimulate both fusarochromanone synthesis and its conversion to TDP-2.
一种先前命名为TDP - 2的荧光化合物是从尖孢镰刀菌(阿拉斯加2 - 2)的水稻培养物中分离并纯化得到的。质谱和核磁共振数据表明它是镰刀菌色原酮的C - 3'-N - 乙酰衍生物,镰刀菌色原酮是一种新发现的霉菌毒素。在高压灭菌的水稻和添加了大豆蛋白胨的察氏培养基上对这两种化合物合成的时间进程研究表明,在培养物中镰刀菌色原酮转化为了TDP - 2。液体培养基中高浓度的蛋白胨可能会刺激镰刀菌色原酮的合成及其向TDP - 2的转化。
