  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).
