The molecule is a homodetic cyclic peptide that consists of L-valine and L-threonine as the amino acid residues. It is isolated from Lissoclinum bistratum and exhibits antitumour activity against the human colon tumour cell line. It has a role as a metabolite and an antineoplastic agent. It is a homodetic cyclic peptide, a macrocycle, a member of 1,3-thiazoles, an organic heterotricyclic compound, a member of 1,3-oxazoles and a secondary carboxamide.
