Marine microorganisms produce macrolactins with various biological activities, making them potential compounds for drug development. These macrolactins are biosynthesized via a type I polyketide synthase pathway, offering opportunities for structural diversification.
Marine microorganisms have proven to be a rich source of natural products with unique structures and novel activities, due to their special living conditions. Macrolactins (MLNs), mostly produced by marine-derived microorganisms, are a group of 24-membered lactone natural products, which exhibit potent antibacterial, antifungal, antiviral, anticancer, anti-inflammatory, anti-angiogenic and other activities. Their extensive biological activities make them potential compounds for drug development. MLNs are biosynthesized via a type I polyketide synthase (PKS) pathway with different tailoring steps, such as epoxidation, glycosylation and acylation. These modification steps provide opportunities to diversify their structures by combinatorial biosynthesis strategies. This review mainly focuses on the newly discovered MLNs in the past five years, including their biological activities and relevant biosynthetic studies.
