FR901533 (1, also known as WS79089B), WS79089A (2), and WS79089C (3) are polycyclic aromatic natural products with promising inhibitory activity to endothelin-converting enzymes. In this work, we isolated five tridecaketide products from Streptosporangium roseum No. 79089, including 1-3, benaphthamycin (4) and a novel FR901533 analogue (5). The structure of 5 was characterized based on spectroscopic data. Compared to the major product 2, the new compound 5 has an additional hydroxyl group at C-12 and an extra methyl group at the 13-OH. The configuration of C-19 of these compounds …
