Abstract
Thelepamide (1) was characterized during a program to study cytotoxic substances from an unusual source, the tidal zone-derived annelid Thelephus crispus. Its structure contains a tetraketide and a tripeptide subunit and possesses striking atom diversity, consisting of 17 carbons and 8 heteroatoms. The relative configurations at four chiral sites were elucidated via ROESY, J-based configurational analysis, and DFT calculations. It was modestly active ...
