Three new 10-membered macrolides, saccharothriolides A-C (1-3), were discovered from a rare actinomycete Saccharothrix sp. A1506. All of the sp(3) carbons in the 10-membered ring had chirality, which was determined by extensive spectroscopic analysis and TDDFT-calculation of ECD spectra. Saccharothriolide B (2) exhibited cytotoxicity against human tumor cell lines HeLa and HT1080.
从一种罕见的放线菌糖丝菌属菌株A1506中发现了三种新的10元大环内酯类化合物，即糖硫内酯A-C（1-3）。10元环中的所有sp(3)碳都具有手性，这是通过广泛的光谱分析和ECD光谱的TDDFT计算确定的。糖硫内酯B（2）对人肿瘤细胞系HeLa和HT1080表现出细胞毒性。
