bacterial luminescence inhibition test with marine luminescent bacteria Photobacterium leiognathi Sh1. The relationship of the structures of the isatin N-substituent and the 5-indolyl substituent and the glycoside capacity to suppress bacterial luminescence was analyzed.
在固体碳酸钾 - 乙腈相转移系统中,通过 α-D-氨基葡萄糖过乙酸酯以高产率糖基化了易去质子化的靛蓝 3-肟羟基。发现催化量的 15-crown-5 支持该过程的两倍加速。得到的β-D-氨基葡萄糖通过1H NMR光谱鉴定。合成化合物的 NMR 谱的具体特征与 N-乙酰葡糖胺的其他 10-衍生物的特征进行了比较。采用海洋发光细菌Photobacterium leiognathi Sh1进行细菌发光抑制试验,研究了靛红残基中不同取代基肟的生物活性。
