Abstract
Two novel angucyclinone-type antibiotics, simocyclinones D4 and D8, were detected in the mycelium extract of Streptomyces antibioticus Tü 6040 by HPLC-diode-array and HPLC-electrospray-mass-spectrometry screening. The compounds show antibiotic activities against Gram-positive bacteria and cytostatic effects on various tumor cell lines.
摘要
通过高效液相色谱-二极管阵列检测法和高效液相色谱-电喷雾质谱筛查法，在抗生链霉菌Tü 6040的菌丝体提取物中检测到两种新型安古洛环酮类抗生素，即西莫环素D4和D8。这些化合物对革兰氏阳性菌具有抗菌活性，并对多种肿瘤细胞系具有细胞抑制作用。
