Cyclo(L-Phe-L-Phe) is a diketopiperazine metabolite first reported by Birkinshaw and Mohammed in 1962 as a metabolite of Penicillium nigricans. Cyclo(L-Phe-L-Phe) was subsequently reported as a metabolite in other fungi and actinomycetes and is a useful standard for chemical and bioassay dereplication. Like other diketopiperazines cyclo(L-Phe-L-Phe) appears in several recent patents covering a diverse range of diketopiperazines with broad therapeutic claims.
