초록

A genomic and spectroscopic signature-based search revealed a cycloaromatized enediyne, jejucarboside A (1), from a marine actinomycete strain. The structure of 1 was determined as a new cyclopenta[a]indene glycoside bearing carbonate functionality by nuclear magnetic resonance, high-resolution mass spectrometry (MS), MS/MS, infrared spectroscopy, and a modified Mosher's method. An iterative enediyne synthase pathway has been proposed for the putative biosynthesis of 1 by genomic analysis. Jejucarboside A exhibited cytotoxicity against the HCT116 colon carcinoma cells.
