(−)-Aurantiamine is a blue fluorescence metabolite produced by the fungus Penicillium aurantiogriseum , the most common fungi found in cereals. [1] (−)-Aurantiamine belongs to a class of naturally occurring 2,5-diketopiperazines featuring a dehydrohistidine residue that exhibit important biological activities, such as anti-cancer or neurotoxic effects. [2] It is the isopropyl analog of the microtubule binding agent (−)-phenylahistin but is 40 times less active than the latter on P388 cell proliferation. [3] The total asymmetric synthesis of (−)-aurantiamine has been described. [4]

The Trichocomaceae are a family of fungi in the order Eurotiales. Taxa are saprobes with aggressive colonization strategies, adaptable to extreme environmental conditions. Family members are cosmopolitan in distribution, ubiquitous in soil, and common associates of decaying plant and food material. The family contains some of the most familiar fungi, such as Penicillium and Aspergillus. It has been proposed that the family should be split into the three families Aspergillaceae, Thermoascaceae and Trichocomaceae.
Penicillium roqueforti is a common saprotrophic fungus in the genus Penicillium. Widespread in nature, it can be isolated from soil, decaying organic matter, and plants.
Spirotryprostatin B is an indolic alkaloid found in the Aspergillus fumigatus fungus that belongs to a class of naturally occurring 2,5-diketopiperazines. Spirotryprostatin B and several other indolic alkaloids have been found to have anti-mitotic properties, and as such they have become of great interest as anti-cancer drugs. Because of this, the total syntheses of these compounds is a major pursuit of organic chemists, and a number of different syntheses have been published in the chemical literature.
Spirotryprostatin A is an indolic alkaloid from the 2,5-Diketopiperazine class of natural products found in the Aspergillus fumigatus fungus. Spirotryprostatin A and several other indolic alkaloids have been found to have anti-mitotic properties, and as such they have become of great interest as anti-cancer drugs. Because of this, the total syntheses of these compounds is a major pursuit of organic chemists, and a number of different syntheses have been published in the chemical literature.
Roquefortine C is a mycotoxin that belongs to a class of naturally occurring 2,5-diketopiperazines produced by various fungi, particularly species from the genus Penicillium. It was first isolated from a strain of Penicillium roqueforti, a species commercially used as a source of proteolytic and lipolytic enzymes during maturation of the blue-veined cheeses, Roquefort, Danish Blue, Stilton and Gorgonzola.
Brevianamides are indole alkaloids that belong to a class of naturally occurring 2,5-diketopiperazines produced as secondary metabolites of fungi in the genus Penicillium and Aspergillus. Structurally similar to paraherquamides, they are a small class compounds that contain a bicyclo[2.2.2]diazoctane ring system. One of the major secondary metabolites in Penicillium spores, they are responsible for inflammatory response in lung cells.
Penicillium chrysogenum is a species of fungus in the genus Penicillium. It is common in temperate and subtropical regions and can be found on salted food products, but it is mostly found in indoor environments, especially in damp or water-damaged buildings. It has been recognised as a species complex that includes P. notatum, P. meleagrinum, and P. cyaneofulvum, but molecular phylogeny established that it is a distinct species and that P. notatum is P. rubens. It has rarely been reported as a cause of human disease. It is the source of several β-lactam antibiotics, most significantly penicillin. Other secondary metabolites of P. chrysogenum include roquefortine C, meleagrin, chrysogine, 6-MSA YWA1/melanin, andrastatin A, fungisporin, secalonic acids, sorbicillin, and PR-toxin.
2,5-Diketopiperazine, also known as piperazine-2,5-dione and as the cyclodipeptide cyclo(Gly-Gly), is an organic compound and the smallest cyclic dipeptide that consists of a six-membered ring containing two amide linkages where the two nitrogen atoms and the two carbonyls are at opposite positions in the ring. It was first synthesized by Curtius and Gloebel in 1888 and was the first compound containing a peptide bond to be studied by X-ray crystallography in 1938. It occurs in cocoa and bread and has a metallic and bitter taste.
A diketopiperazine (DKP), also known as a dioxopiperazine or piperazinedione, is a class of organic compounds related to piperazine but with two amide linkages. Three regioisomers are possible, differing in the locations of the carbonyl groups.
Fumitremorgins are tremorogenic metabolites of Aspergillus and Penicillium, that belong to a class of naturally occurring 2,5-diketopiperazines.
Fellutanine A, B, C and D are bio-active diketopiperazine alkaloids isolated from the cultures of Penicillium fellutanum, that belongs to a class of naturally occurring 2,5-diketopiperazines. Originally they were thought to be based on the "trans" cyclic dipetide cyclo(L-Trp-D-Trp) but were later shown to be based on the "cis" cyclic dipetide cyclo(L-Trp-L-Trp). This was also confirmed when fellutanine A, B and C were isolated from Penicillium simplicissimum. The fellutanines A−C, are non-annulated analogues of cyclo(L-Trp-L-Trp), but unlike their diannulated analogue fellutanine D are not cytotoxic.
Verruculogen is a mycotoxin produced by certain strains of aspergillus that belongs to a class of naturally occurring 2,5-diketopiperazines. It is an annulated analogue of cyclo(L-Trp-L-Pro) which belongs to the most abundant and structurally diverse class of tryptophan-proline 2,5-diketopiperazine natural products. It produces tremors in mice due to its neurotoxic properties. It also tested positive in a Salmonella/mammalian microsome assay and was shown to be genotoxic. It is a potent blocker of calcium-activated potassium channels.
Piscarinines are bioactive alkaloid isolates of Penicillium piscarium NKM F-961 and Penicillium piscarium Westling that belong to a class of naturally occurring 2,5-diketopiperazines. The cytotoxic dehydroproline tryptophan derivatives piscarinines A and B were shown to be active against the prostate cancer cell line LNCAP.

Rugulosuvines are bio-active alkaloids made by Penicillium, that belongs to a class of naturally occurring 2,5-diketopiperazines.

Yaequinolone J1 is an antibiotic made by Penicillium.
Auranthine is an antimicrobial chemical compound isolated from a nephrotoxic strain of Penicillium fungus, Penicillium aurantiogriseum.
(-)-Versicolamide B and (+)-Versicolamide B are spiroindole alkaloids isolated from the fungus Aspergillus that belong to a class of naturally occurring 2,5-diketopiperazines. The versicolamides are structurally complex spiro-cyclized versions of prenylated cyclo(L-Trp-L-Pro) derivatives which possess a unique spiro-fusion to a pyrrolidine at the 3-position of the oxindole core together with the bicyclo[2.2.2]diazaoctane ring system. While (-)-versicolamide B was isolated from the marine fungus Aspergillus sp. the enantiomer (+)-versicolamide B was isolated from the terrestrial fungi Aspergillus versicolor NRRL. The total asymmetric syntheses of both enantiomers have been achieved and the implications of their biosynthesis have been investigated.
Dideoxyverticillin A, also known as (+)-11,11’-dideoxyverticillin A, is a complex epipolythiodioxopiperazine initially isolated from the marine fungus Penicillium sp. in 1999. It has also been found in the marine fungus Bionectriaceae, and belongs to a class of naturally occurring 2,5-diketopiperazines.
Penicillium dipodomyis is a species of the genus of Penicillium which occurs in kangaroo rats and produces penicillin and the diketopiperazine dipodazine.
Penicillium spinulosum is a non-branched, fast-growing fungus with a swelling at the terminal of the stipe (vesiculate) in the genus Penicillium. P. spinulosum is able to grow and reproduce in environment with low temperature and low water availability, and is known to be acidotolerant. P. spinulosum is ubiquitously distributed, and can often be isolated from soil. Each individual strain of P. spinulosum differs from others in their colony morphology, including colony texture, amount of sporulation and roughness of conidia and conidiophores.
