Chaetomin (CAT: I014001) is an epidithiodioxopiperazine metabolite initially discovered as an antibiotic. It was first isolated from Chaetomium cichlids and had a unique structure composed of a non-symmetric bis-epidithiodioxopiperazine with both hemispheres containing a core N,N’-dimethyldiketopiperazine linked by a disulfide bridge. Chaetomin has been widely used as a chemotaxonomic marker for identifying the genus Chaetomium. In addition to its antibiotic properties, chaetomin has demonstrated potent antitumor activity by inhibiting hypoxia-inducible transcription. It shows potential as an anticancer agent, particularly in targeting hypoxic tumor microenvironments.
