In 2004, MCP1001 (1) was isolated from a fungal strain
Cladorrhinum sp. KY4922 in Indonesia and has subsequently shown
antiproliferative activity against a human prostate cancer cell line
(DU145).1 The structure was determined by numerous NMR experiments as
well as FAB-MS analysis.2 The characterization revealed a
fifteen-membered macrocycle containing a unique diketopiperazine with a
disulfide bridge fused to a seven-membered oxepin moiety. These unique
structural features belong to a class of compounds known as
epipolythiodioxopiperazines (ETP).
