Two new indole alkaloids, metagenetriindole A (1) and metagenebiindole A (2), were identified from deep-sea sediment metagenomic clone derived Escherichia coli fermentation broth. The structures of new compounds were elucidated by spectroscopic methods. The two new indole alkaloids demonstrated moderately cytotoxic activity against CNE2, Bel7402 and HT1080 cancer cell lines in vitro.
