S. Gupta et al., CHARACTERIZATION OF A PHYTOTOXIC CYCLOTETRAPEPTIDE, A NOVEL CHLAMYDOCIN ANALOG, FROM VERTICILLIUM-COCCOSPORUM, Tetrahedron letters, 35(33), 1994, pp. 6009-6012
A phytotoxic cyclotetrapeptide containing an unusual amino acid, 2-ami
no-8-oxo-9-hydroxydecanoic acid, was isolated from the fungus Verticil
lium coccosporum. Structurally, the peptide is closely related to the
known peptide chlamydocin.
