Fellutanine

Fellutanine A,[1] B,[1] C and D are bio-active diketopiperazine alkaloids isolated from the cultures of Penicillium fellutanum,[2] that belongs to a class of naturally occurring 2,5-diketopiperazines.[3] Originally they were thought to be based on the "trans" cyclic dipetide cyclo(L-Trp-D-Trp) [2] but were later shown to be based on the "cis" cyclic dipetide cyclo(L-Trp-L-Trp).[4] This was also confirmed when fellutanine A, B and C were isolated from Penicillium simplicissimum.[5] The fellutanines A−C, are non-annulated analogues of cyclo(L-Trp-L-Trp), but unlike their diannulated analogue fellutanine D are not cytotoxic.
