Cyclochlorotine[1] (CC), also known as islanditoxin[2] is a mycotoxin produced by the fungus Penicillium islandicum[3] that causes liver damage and has carcinogenic properties.[4] Japanese researchers confirmed that it was one of three strains of Penicillin fungi responsible for yellowed rice.[2] It is listed as an IARC Group 3 carcinogen.

Chemically, it is a dichlorinated cyclic peptide.[5] Structurally, the only thing that differentiates cyclochlorotine from the plant-derived astins of Aster tataricus, is replacement of a serine with a second 2-aminobutyrate.[6]
