Three new cyclic lipopeptides, olenamidonins A-C (-), in addition to two previously reported metabolites ( and ), were accumulated in the Δ deletion mutant of deepsea-derived SCSIO 1071. The structures of these cyclic lipopeptides were determined by a combination of spectroscopic methods and circular dichroism (CD) measurement. The antibacterial assay results showed that compounds displayed different degrees of growth inhibition against multidrug-resistant (MDR) bacterial strains CCARM 5172 and CCARM 5203 with minimum inhibitory concentrations (MICs) of 1.56-6.25 μg/mL.
