Two lipohexapeptides, mariannamides C (1) and D (2), were isolated from Mariannaea elegans NBRC102301, a filamentous fungus isolated from a decayed Pinus densiflora needle. The stereochemistries of 1 and 2 were fully elucidated based on Marfey’s method and modified phenylglycine methyl ester method. Mariannamides C (1) and D (2) significantly and selectively promoted the defatty-acylase activity of sirtuin 3.
