Chaetoglobosin A
Chaetoglobosin A, the active principle within the extract of Penicillium aquamarinium, is a member of the cytochalasan family. Chaetoglobosin A preferentially induces apoptosis. Chaetoglobosin A targets filamentous actin in CLL cells and thereby induces cell-cycle arrest and inhibits membrane ruffling and cell migration[1].
