从都托霉素(1)生产者链霉素的培养液中分离出一种神经保护化合物(2)。RAP 78.通过高分辨快原子轰击质谱(FAB-MS)确定化合物2的分子式为C44 H55 NO16,通过核磁共振波谱分析确定其结构为一种新的具有乙酰亚氨基取代乙酰基的度托霉素衍生物。13-脱氧-13-亚氨基度托霉素(2)而非度托霉素(1)可保护C6大鼠胶质瘤细胞和N18-RE-105大鼠原代视网膜-小鼠神经母细胞瘤杂交细胞免受谷氨酸诱导的毒性,EC 50分别为0.12 µM和0.72 µM。
A neuroprotective compound (2) was isolated from the culture broth of the dutomycin (1) producerStreptomycessp. RAP78. The molecular formula of2was established as C44H55NO16by high-resolution FAB-MS. The structure was determined to be a new dutomycin derivative possessing an acetimidoyl group in place of an acetyl group by NMR spectroscopic analysis. 13-Deoxo-13-iminodutomycin (2) but not dutomycin (1) protected C6 rat glioma cells and N18-RE-105 rat primary retina-mouse neuroblastoma hybrid cells from glutamate-induced toxicity with EC50s of 0.12 µM and 0.72 µM, respectively.
