P388 murine leukemias in vivo. In these systems, the inhibitory activity of the 7-substituted analogs was comparable to actinomycin D. In two bacterial systems ( (L. casei and L. arabinosus) in vitro, on the other hand, these compounds showed inhibitory profiles which are distinctly different from actinomycin D. These studies demonstrate that substitution at the 7 position, which does not interfere with
报道了三种7-取代的放线菌素D衍生物的合成和生物学活性。通过新方法合成了三种这样的衍生物7-硝基-,7-氨基-和7-羟基放线菌素D,该方法首先在发色团模型系统中成功进行了测试。其中7-硝基和7-氨基放线菌素D在体外和体内对Ridgway成骨肉瘤以及L1210,P1534和P388鼠白血病对哺乳动物细胞(CCRF-CEM人淋巴细胞白血病)的生长抑制活性进行了测定。在这些系统中,7-取代类似物的抑制活性可与放线菌素D相媲美。另一方面,在体外的两个细菌系统(干酪乳杆菌和阿拉伯乳杆菌)中,这些化合物显示出明显不同的抑制谱来自放线菌素D。
