  • Bicyclomycin
    Bicyclomycin (Bicozamycin) is a broad spectrum antibiotic active against Gram-negative bacteria and the Gram-positive bacterium, Micrococcus luteusn that was isolated from Streptomyces sapporonesis and Streptomyces aizumenses in 1972.
  • Brevianamide F
    Brevianamide F , also known as cyclo-(L-Trp-L-Pro), belongs to a class of naturally occurring 2,5-diketopiperazines.
  • Retosiban
    Retosiban (GSK-221,149-A) is an oral drug which acts as a selective, sub-nanomolar (Ki = 0.65 nM) oxytocin receptor antagonist with >1400-fold selectivity over the related vasopressin receptors and is being developed by GlaxoSmithKline for the treatment of preterm labour.
  • Rhodotorulic acid
    Rhodotorulic acid is the smallest of the 2,5-diketopiperazine family of hydroxamate siderophores which are high-affinity chelating agents for ferric iron, produced by bacterial and fungal phytopathogens for scavenging iron from the environment.
  • Brevianamide
    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.
  • Epelsiban
    Epelsiban (INN, USAN, code name GSK-557,296-B) is an orally bioavailable drug which acts as a selective, sub-nanomolar (Ki = 0.13 nM) oxytocin receptor antagonist with >31,000-fold selectivity over the related vasopressin receptors and is being developed by GlaxoSmithKline for the treatment of premature ejaculation in men and as an agent to enhance embryo or blastocyst implantation in women undergoing embryo or blastocyst transfer associated with in vitro fertilization (IVF).
  • Gliotoxin
    Gliotoxin is a sulfur-containing mycotoxin that belongs to a class of naturally occurring 2,5-diketopiperazines produced by several species of fungi, especially those of marine origin.
  • 2,5-Diketopiperazine
    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.
  • Verruculogen
    Verruculogen is a mycotoxin produced by certain strains of aspergillus that belongs to a class of naturally occurring 2,5-diketopiperazines.

    (−)-Aurantiamine is a blue fluorescence metabolite produced by the fungus Penicillium aurantiogriseum, the most common fungi found in cereals.
  • Phenylahistin
    Phenylahistin is a metabolite produced by the fungus Aspergillus ustus that 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.
