Systematic Review Maps Biogenesis, Diversity, and Bioactivities of 19 Classes of Cyanobacteria-Derived Linear Peptides
Background
Cyanobacteria, ancient photosynthetic Gram-negative prokaryotes, are prolific producers of diverse secondary metabolites, including a wide array of peptides. The vastness of marine environments, covering over 70% of Earth's surface, represents an underexplored source of unique bioactive compounds. While numerous studies have investigated individual cyanobacteria-derived linear peptides, a systematic and comprehensive overview summarizing their diverse research progress has been lacking. This gap hinders a holistic understanding of their therapeutic potential and structural characteristics.
Study Design
This article provides a systematic overview of research progress on 19 classes of well-studied cyanobacteria-derived linear peptides. The review focuses on their biogenesis, structural diversity, biosynthesis, and bioactivities. It categorizes these peptides into short-chain linear peptides, fatty acid modified linear peptides, linear peptides containing specialized cyclic moieties, and long-chain linear peptides, synthesizing existing knowledge across these distinct structural groups.
Results
The review highlights the remarkable structural diversity and versatile bioactivities of linear peptides from cyanobacteria. These compounds have emerged as promising candidates for drug development due to their inherent structural modifiability and broad pharmacological effects. Integrated chemical and biosynthetic strategies are presented as novel approaches to enhance production efficiency and optimize pharmacological properties. The review identifies 19 distinct classes of linear peptides, underscoring their varied structures. These peptides exhibit significant potential as therapeutic agents, demonstrating efficacy across multiple domains.
They are identified as promising candidates for developing anticancer, anticoagulant, anti-inflammatory, and antiparasitic agents.
