Ternatin is a cyclic heptapeptide first isolated from the mushroom C. versicolor that has been shown to have cytotoxic and anti-adipogenic effects in vitro. It inhibits adipogenesis with an IC50 value of 27 nM and becomes cytotoxic to 3T3-L1 mouse adipocytes at 10-fold higher concentrations. Ternatin is reported to inhibit HCT116 cell proliferation with an IC50 value of 71 nM. Note that this metabolite should not be confused with the plant flavonoid of the same name.
