Amidepsine D is a fungal depside structurally related to DGAT-inhibiting amidepsines and studied as a lipid biosynthesis scaffold.
Details
Amidepsine D is a fungal secondary metabolite isolated from the DGAT inhibitor-producing strain Humicola sp. FO-2942. Structural analysis identified amidepsine D as 2,4-di-O-methylgryphoric acid, a depside-type aromatic compound. Unlike amidepsines A-C, which possess N-alanine or N-valine amide moieties and exhibit DGAT inhibitory activity, amidepsine D corresponds to a methylated gryphoric acid derivative and represents a structurally related metabolite from the same biosynthetic context.
