Two new cyclic octapeptides, mariannamides A (1) and B (2), have been isolated from Mariannaea elegans NBRC102301, a Pinus densiflora-derived filamentous fungus. Their structures were elucidated to be cyclo-(L-Leu1-L-Pro1-L-Pro2-L-Leu2-L-Ile1-L-Pro3-L-Val1-L-Ile2) and cyclo-(L-Leu1-L-Pro1-L-Pro2-L-Leu2-L-Ile1-L-Pro3-L-Val1-L-Val2) based on spectroscopic data and Marfey's method. Mariannamide A (1) promoted mRNA expression of sirtuin 1 (SIRT1) in C2C12 cells, a mouse skeletal muscle myoblast cell line, and showed the antimicrobial activity against Escherichia coli and Cryptococcus neoformans.
