Piscarinines are bioactive alkaloid isolates of Penicillium piscarium NKM F-961 [1] and Penicillium piscarium Westling [2] that belong to a class of naturally occurring 2,5-diketopiperazines.[3] The cytotoxic dehydroproline tryptophan derivatives piscarinines A and B were shown to be active against the prostate cancer cell line LNCAP [2] (IC50 values were 2.2 and 1.9 μg/mL for piscarinine A and B, respectively).
