Aspochracin is an insecticidal non-proteogenic cyclic tripeptide first isolated from Aspergillus ochraceus by Myokei and co-workers at University of Tokyo in 1969. The same authors elucidated its structure which comprises N-methylalanine, N-methylvaline and an ornithine cyclised through the delta rather than the alpha-amino group. The alpha-amino moiety is acylated with an octa-2,4,6-trienoic acid. Aspochracin is known to be non-toxic to mammalian cell lines and its biological activity and pharmacology are largely unexplored.
