The antitumor antibiotic ‘rubiflavin’ was investivated. It was shown to be a mixture of several compounds, nine of which - after isolation by HPLC - could be identified by 1H-NMR spectroscopy. The rubiflavins A (4), B (5), C-1(6), C-2(7), D(8), and E(9) are pluramycin antibiotics differing only in their side chains at C(2). Rubiflavin B(5) was found to be identical with kidamycin, rubiflavin F(10)
研究了抗肿瘤抗生素“ rubiflavin”。它显示为几种化合物的混合物,其中9种-通过HPLC分离后-可以通过1 H-NMR光谱鉴定。茜草素A(4),B(5),C-1(6),C-2(7),D(8)和E(9)是普乐霉素抗生素,仅在C(2)的侧链不同。 。发现茜草素B(5)与Kidamycin相同,茜草素F(10)与异黄霉素相同。分离出的两种非极性化合物缺少普鲁霉素抗生素通常具有的两个糖环,分别称为茜草素C-1(2)和C-2(3); 它们是相应的茜草素的“糖苷配基”。
