Glucosylquestiomycin, a Novel Antibiotic from Microbispora sp. TP-A0184: Fermentation, Isolation, Structure Determination,Synthesis and Biological Activities.
摘要:
从小孢子菌 TP-A0184 的培养液中分离出了喹霉素 A 的新型 N-吡喃葡萄糖苷。通过化学合成确定了糖的绝对构型为 D-构型。这种新抗生素对革兰氏阳性和阴性细菌及酵母菌具有抗菌活性,对 U937 细胞具有细胞毒性。

Glucosylquestiomycin, a novel N-glucopyranoside of questiomycin A, was isolated from the culture broth of Microbispora sp. TP-A0184. The absolute configuration of the sugar was determined as D-configuration by chemical synthesis. The new antibiotic showed antibacterial activity against Gram-positive and -negative bacteria and yeasts and cytotoxic activity against U937 cells.
