Two new 24-membered macrolides, SPA-6952A and B, were isolated from the fermentation broth of Streptomyces sp. SPA-6952. The structures of the new macrolides were determined by spectral analyses, including 2D NMR techniques. These compounds exhibited cytotoxic activity against human promyelocytic leukemia HL-60 cells.
从链霉菌属菌株SPA-6952的发酵液中分离出两种新的24元大环内酯类化合物,SPA-6952A和B。通过光谱分析,包括二维核磁共振技术确定了这些新大环内酯类化合物的结构。这些化合物对人早幼粒细胞白血病HL-60细胞表现出细胞毒性活性。
