New Tripeptide Derivatives Asterripeptides A–C from Vietnamese Mangrove-Derived Fungus Aspergillus terreus LM.5.2

Three new tripeptide derivatives asterripeptides A–C (1–3) were isolated from Vietnamese mangrove-derived fungus Aspergillus terreus LM.5.2. Structures of isolated compounds were determined by a combination of NMR and ESIMS techniques. The absolute configurations of all stereocenters were determined using the Murfey’s method. The isolated compounds 1–3 contain a rare fungi cinnamic acid residue. The cytotoxicity of isolated compounds against several cancer cell lines and inhibition ability of sortase A from Staphylococcus aureus of asterripeptides A–C were investigated.
