Aspochracin is a cyclic tripeptide originally isolated from the pathogenic fungus A. ochraceus, which infects insects. Aspochracin is toxic to fall webworms (LD50 = 100 µg/g) and to silkworms. Unlike other aspochracin-type cyclic tripeptides, it has no antifungal activity against C. albicans and does not have antimicrobial activity up to a concentration of 0.1 mg/ml.

JBIR-15, a new Aspochracin derivative, isolated from a sponge-derived fungus, Aspergillus sclerotiorum Huber Sp080903f04
Biosci Biotechnol Biochem 2009 Aug;73(8):1898-900.PMID:19661713DOI:10.1271/bbb.90228.
In the course of our chemical screening program for novel metabolites by LC-MS monitoring, we isolated a new Aspochracin derivative, JBIR-15 (1), together with Aspochracin, from the culture broth of a sponge-derived fungus, Aspergillus sclerotiorum Huber Sp080903f04. The structure of 1 was determined to be N-demethyl Aspochracin at the alanyl residue on the basis of extensive NMR and MS analyses.
Cyclic tripeptides from the halotolerant fungus Aspergillus sclerotiorum PT06-1
J Nat Prod 2010 Jun 25;73(6):1133-7.PMID:20503985DOI:10.1021/np100198h.
Eleven new aspochracin-type cyclic tripeptides, sclerotiotides A-K (1-11), together with three known compounds, JBIR-15 (12), Aspochracin (13), and penicillic acid, were isolated from the ethyl acetate extract of the fermentation broth of the halotolerant Aspergillus sclerotiorum PT06-1 in a hypersaline nutrient-rich medium. Their structures were elucidated by spectroscopic analysis and chemical methods. Chemical transformations of 12 and 13 proved that sclerotiotides D-K (4-11) were artifacts probably formed during the fermentation or subsequent isolation steps. All 13 cyclic tripeptides have been evaluated for their antimicrobial and cytotoxic effects. Only sclerotiotides A (1), B (2), F (6), and I (9) and JBIR-15 (12) showed selective antifungal activity against Candida albicans with MIC values of 7.5, 3.8, 30, 6.7, and 30 microM, respectively.
