Fumagillin is a complex biomolecule and used as an antimicrobial agent. It was isolated in 1949 from the microbial organism Aspergillus fumigatus. Fumagillin has been used in the treatment of microsporidiosis. It is also an amebicide. Fumagillin can block blood vessel formation by binding to an enzyme methionine aminopeptidase and for this reason, the compound, together with semisynthetic derivatives, are investigated as an angiogenesis inhibitor in the treatment of cancer.
